The pediatric surgery nurse’s communication challenge in the perioperative unit
Pediatric surgical nursing demands a kind of explanatory precision that few other specialties require. In the emergency department, the nurse explains what is happening to a body under acute threat. On the post-operative floor, the nurse must explain what a body needs to do — and not do — to heal correctly. The instructions are not intuitive. They contradict the family’s instincts. And they are non-negotiable: a family that does not understand the instruction will not follow it.
Three communication failures recur with particular frequency in pediatric perioperative care with Spanish-speaking families.
The first is the pre-operative fast. A parent brings a child in for an elective procedure only to find that the child is not allowed to drink water — not juice, not formula, not even water — for hours before the operation. The child is thirsty and upset. The restriction seems arbitrary and needlessly cruel. The parent cannot understand what water has to do with surgery. The nurse must explain that the danger is not in the water itself but in what general anesthesia does to the airway: it abolishes the reflexes that prevent liquid from entering the lungs, so an empty stomach becomes the only barrier between gastric contents and the alveolar epithelium.
The second is early post-operative ambulation. A family watches a child wince in pain at every position change and cannot understand why the nurse is asking the child to stand up and walk to the hallway hours after the procedure. The instruction seems to contradict what recovery should look like. The nurse must explain that immobility after surgery generates three specific, preventable complications — atelectasis, deep vein thrombosis, and post-operative ileus — and that walking is the intervention that prevents all three through distinct physiological mechanisms that pharmacology cannot fully replicate.
The third is total parenteral nutrition during bowel rest. A family is told that the child cannot eat or drink anything because the bowel needs to rest after intestinal surgery — and then watches a bag labeled “nutrition” flow through an intravenous line. The contradiction seems nonsensical. The nurse must explain that parenteral nutrition bypasses the intestinal lumen entirely, delivering all nutritional components directly to the bloodstream through the central venous catheter, so the body receives complete nutrition while the anastomosis remains undisturbed.
Three conversations from pediatric surgical nursing:
Scenario 1: Camila Torres-Ríos — 4 years old, Houston, Texas
Camila Torres-Ríos had been scheduled for an elective laparoscopic repair of a right indirect inguinal hernia for six weeks. The surgery had been postponed twice — once when Camila developed a respiratory infection the week before the original date, once when the surgical suite overbooked. The third date had finally held, and Rosa Torres had arranged everything: a neighbor to watch her two older children, a day off from her housekeeping job at the hotel downtown, a babysitter for the afternoon pickup. She had followed the pre-operative instructions carefully. She thought.
At 6:30 AM on the morning of the surgery, Rosa was sitting in the pre-operative holding area with Camila on her lap when the nurse came in to review the pre-operative checklist. Camila was dressed in a small surgical gown and was clutching a stuffed rabbit she had brought from home. She had not eaten since the previous evening. Rosa had been meticulous about the solid food restriction — she understood that part. But at 5 AM, when Camila woke up crying and asking for water, Rosa had given her a small amount — “maybe a few sips, not much, just to calm her down” — about ninety minutes before they left the house.
Pre-operative nurse Alejandra Fuentes-Morales asked the question in the same order she always did, making her way through the checklist: last solid food, last formula, last breast milk, last clear liquids.
“Agua,” Rosa said. “Como a las cinco de la mañana. Solo un poquito. Porque estaba llorando.” (Water. Around five in the morning. Just a little. Because she was crying.)
Alejandra marked the time. It was 6:38 AM now. One hour and thirty-eight minutes since Camila’s last clear liquid. The guidelines required two hours minimum. They were under the threshold.
She looked at Rosa, who had already seen the shift in her expression and understood that something was wrong.
“¿Hay un problema?” (Is there a problem?)
“Voy a explicarle la situación,” Alejandra said. “Y quiero explicarle bien, porque necesito que entienda por qué este tiempo importa — no como una regla burocrática, sino porque hay algo concreto que estamos tratando de evitar.” (I am going to explain the situation. And I want to explain it well, because I need you to understand why this time matters — not as a bureaucratic rule, but because there is something specific we are trying to prevent.)
Rosa shifted Camila on her lap. Camila was watching the nurse with the steady, evaluative gaze of a four-year-old who has learned to read adult faces. “Adelante,” Rosa said. (Go ahead.)
“La anestesia general — los medicamentos que hacen que Camila esté completamente dormida durante la operación — no solo duermen el cerebro. Apagan los reflejos del tronco cerebral que protegen la garganta cuando estamos despiertos. En este momento, si a Camila le entra cualquier cosa por la garganta equivocada, su cuerpo lo detecta de inmediato. Sus cuerdas vocales se cierran. La epíglotis — la lengeta que tapa el camino de los pulmones cuando tragamos — se baja. Y si algo llega a la tráquea de todos modos, tose. Esos tres reflejos funcionan solos, sin que ella tenga que pensar, cuando está despierta. Bajo la anestesia, los tres reflejos se apagan.” (General anesthesia — the medications that make Camila completely asleep during the operation — does not only put the brain to sleep. It shuts down the brainstem reflexes that protect the throat when we are awake. Right now, if anything goes down Camila’s throat the wrong way, her body detects it immediately. Her vocal cords close. The epiglottis — the flap that covers the airway when we swallow — goes down. And if anything reaches the trachea anyway, she coughs. Those three reflexes work on their own, without her having to think, when she is awake. Under anesthesia, all three reflexes are switched off.)
Rosa was very still, listening. Camila had put her chin on Rosa’s shoulder and was looking at the monitor across the room.
“Además, la anestesia relaja el esfínter que hay entre el estómago y el esófago — la válvula que mantiene el contenido del estómago adentro. Cuando esa válvula se relaja y el estómago tiene líquido, el líquido puede subir solo por el esófago. En condiciones normales, los reflejos de la garganta lo bloquearían. Bajo la anestesia, no hay nada que lo bloquee. El líquido puede entrar a la tráquea, bajar a los pulmones, y el cuerpo no lo detecta ni lo expulsa porque los reflejos están apagados.” (In addition, anesthesia relaxes the sphincter between the stomach and the esophagus — the valve that keeps stomach contents inside. When that valve relaxes and the stomach has liquid, the liquid can rise on its own up the esophagus. Under normal conditions, the throat reflexes would block it. Under anesthesia, there is nothing to block it. The liquid can enter the trachea, go down into the lungs, and the body does not detect it or expel it because the reflexes are switched off.)
“¿Y si entra a los pulmones?” (And if it enters the lungs?)
“El ácido del estómago es muy fuerte — mucho más ácido que el vinagre. Cuando ese ácido llega a los pulmones, quema el tejido de los alvéolos — las pequeñas bolsitas donde el oxígeno pasa a la sangre. Esa quemadura causa una inflamación grave que puede causar insuficiencia respiratoria. Es una complicación muy seria. Y es completamente prevenible si el estómago está vacío cuando empieza la anestesia.” (The acid in the stomach is very strong — much more acidic than vinegar. When that acid reaches the lungs, it burns the tissue of the alveoli — the small sacs where oxygen passes into the blood. That burn causes severe inflammation that can cause respiratory failure. It is a very serious complication. And it is completely preventable if the stomach is empty when anesthesia begins.)
Rosa looked at Camila. Camila had begun to pick at a loose thread on her rabbit’s ear, absorbed.
“¿Entonces el agua que le di a las cinco…?” Rosa’s voice was careful. (So the water I gave her at five…?)
“El estómago de Camila va a tardar entre una y dos horas en vaciar líquidos claros como el agua. Para las siete de la mañana, el estómago probablemente esté vacío. Las guías de seguridad requieren mínimo dos horas de ayuno para líquidos claros desde el último sorbo — para tener ese margen de seguridad. Ahora mismo llevamos una hora cuarenta desde que la tomó. Necesitamos esperar veinte minutos más para que el equipo de anestesia pueda evaluar si procede. Yo los voy a conectar con el anestesiólogo para que tome esa decisión.” (Camila’s stomach will take one to two hours to empty clear liquids like water. By seven in the morning, the stomach will probably be empty. The safety guidelines require a minimum of two hours of fasting for clear liquids from the last sip — to have that safety margin. Right now we are at one hour and forty minutes since she drank it. We need to wait twenty more minutes so the anesthesia team can evaluate whether to proceed. I am going to connect you with the anesthesiologist so they can make that decision.)
Rosa exhaled. “No sabía que el agua contaba. Yo pensé que era solo la comida.” (I did not know that water counted. I thought it was only food.)
“Es la parte que la mayoría de las familias no sabe. No está en el resumen de una página, o si está no queda claro. La explicación que le acabo de dar — sobre los reflejos y el ácido del estómago — es la razón por la que el agua también cuenta. Con esa razón entendida, tiene sentido. Sin ella, parece innecesariamente estricto.” (It is the part most families do not know. It is not in the one-page summary, or if it is there it is not clear. The explanation I just gave you — about the reflexes and the stomach acid — is the reason why water also counts. With that reason understood, it makes sense. Without it, it seems unnecessarily strict.)
Camila had shifted around on Rosa’s lap to look at the nurse with her rabbit held in both arms. “Mamá, ¿cuándo me operan?” (Mama, when do they operate on me?)
“Pronto, mi amor,” Rosa said. “Esperamos un ratito más.” (Soon, my love. We wait a little more.)
She looked at the nurse. “Entonces no es una regla arbitraria,” Rosa said. “Es que bajo la anestesia, el cuerpo de Camila no puede proteger sus pulmones solo. El estómago vacío es la única protección que funciona cuando los reflejos están dormidos.” (So it is not an arbitrary rule. It is that under anesthesia, Camila’s body cannot protect its own lungs. An empty stomach is the only protection that works when the reflexes are asleep.)
“Exactamente eso,” Alejandra said. “En veinte minutos hablamos con el anestesiólogo y procedemos.” (Exactly that. In twenty minutes we speak with the anesthesiologist and proceed.)
Scenario 2: Sebastián Morales-Espinoza — 9 years old, San Antonio, Texas
Sebastián Morales-Espinoza had been brought to the pediatric emergency department at 11:30 PM on a Tuesday with a two-day history of periumbilical pain that had migrated to the right lower quadrant. His temperature was 38.7°C. A CT scan of the abdomen confirmed perforated appendicitis with a small periappendiceal abscess and no free perforation. The pediatric surgical team took him to the operating room at 2:15 AM for a laparoscopic appendectomy — three small incisions, including one at the umbilicus, one in the right lower quadrant, and one in the suprapubic region. The procedure lasted 58 minutes. Sebastián was moved to the post-operative floor at 5:30 AM.
His father Ernesto Morales arrived at the hospital at 8 AM, having learned about the emergency when he came home from his overnight construction shift to find a note from his wife saying that she and Sebastián were at the hospital. Ernesto was a site foreman on a commercial construction project and was the kind of person who organized complexity for a living. He had sat with Sebastián through the morning, watching the drip of the IV, monitoring the numbers on the monitor, and asking careful questions of anyone who came into the room.
At 10 AM, post-operative nurse Valeria Ramírez-Castillo came into the room and checked Sebastián’s assessment: vital signs stable, pain 5/10 at rest, 7/10 with movement, bowel sounds absent in all four quadrants, three incision sites clean and dry, no fever since 9 AM. She gave Sebastián oral acetaminophen and ketorolac as ordered — the post-operative analgesic protocol for this surgeon specifically avoided opioids in the first 24 hours for laparoscopic appendectomy to preserve bowel function.
She waited twenty minutes for the medications to take effect, then returned.
“Sebastián, necesito que nos levantemos a dar unos pasos al pasillo. No mucho — hasta la puerta y de vuelta, o hasta donde podamos llegar cómodamente.” (Sebastián, I need us to get up and take a few steps to the hallway. Not much — to the door and back, or as far as we can reach comfortably.)
Sebastián looked at the nurse, then at his father. “Me duele,” he said. (It hurts.)
“Lo sé. El dolor es real,” Valeria said. “Y le acabamos de dar los medicamentos para el dolor exactamente por eso. Pero necesito explicarle a su papá por qué esto es tan importante, porque sé que parece que no tiene sentido.” (I know. The pain is real. And we just gave him the pain medications exactly for that. But I need to explain to your father why this is so important, because I know it seems like it does not make sense.)
Ernesto had straightened in his chair. He was a man who preferred to understand why before he agreed to anything. “Adelante,” he said. (Go ahead.)
“Cuando Sebastián quedó en cama después de la cirugía esta madrugada, el cuerpo empezó a correr tres riesgos que son complicaciones conocidas de cualquier cirugía abdominal en un paciente que no se mueve. Los tres son prevenibles. Y caminar — no trotar, no nada brusco, caminar — es lo que los previene. Quiero explicarle los tres, porque cuando entienda los tres, la caminata tiene sentido.” (When Sebastián was left in bed after the surgery early this morning, the body began running three risks that are known complications of any abdominal surgery in a patient who does not move. All three are preventable. And walking — not jogging, not anything jarring, walking — is what prevents them. I want to explain the three, because when you understand the three, the walk makes sense.)
Ernesto nodded.
“El primero son los pulmones. Cuando una persona está tumbada — especialmente después de una anestesia general que redujo la fuerza del movimiento normal de los pulmones — las partes más bajas de los pulmones, las que están más cerca de la camilla, se comprimen por el peso de los órganos abdominales que se desplazan hacia arriba. Esas zonas reciben menos aire con cada respiración. Los alvéolos — las pequeñas bolsitas donde el oxígeno pasa a la sangre — se colapsan. Cuando se colapsan, las secreciones se acumulan ahí. Si esas secreciones se infectan, es pulmonía. Caminar requiere que Sebastián respire más profundo que tumbado. El diafragma se mueve con más fuerza. Los alvéolos colapsados se abren de nuevo. El riesgo de pulmonía baja.” (The first is the lungs. When a person is lying down — especially after a general anesthetic that reduced the force of normal lung movement — the lowest parts of the lungs, the ones closest to the stretcher, are compressed by the weight of the abdominal organs shifting upward. Those areas receive less air with each breath. The alveoli — the small sacs where oxygen passes into the blood — collapse. When they collapse, secretions pool there. If those secretions get infected, it is pneumonia. Walking requires Sebastián to breathe more deeply than when lying down. The diaphragm moves with more force. The collapsed alveoli open again. The pneumonia risk decreases.)
Ernesto was leaning forward slightly, elbows on knees, listening. On the bed, Sebastián had gone still — he was listening too.
“El segundo son las venas de las piernas. La cirugía pone el cuerpo en un estado donde la sangre coagula más fácilmente — es una respuesta normal al daño del tejido. Y cuando alguien no camina, la sangre se mueve muy lentamente por las venas profundas de las piernas — porque sin los músculos de la pantorrilla contraypendose con cada paso, no hay nada que la empuje hacia arriba contra la gravedad. Si la sangre se estánca en esas venas, puede formarse un coágulo. Si ese coágulo llega al pulmón — que se llama un émbolo pulmonar — es una emergencia grave. El acto de caminar activa los músculos de la pantorrilla. Cada vez que Sebastián dá un paso, esos músculos se contraen y empujan la sangre hacia el corazón. Ese movimiento es la protección.” (The second is the veins in the legs. Surgery puts the body in a state where blood clots more easily — a normal response to tissue damage. And when someone does not walk, blood moves very slowly through the deep veins of the legs — because without the calf muscles contracting with each step, there is nothing to push it upward against gravity. If blood stagnates in those veins, a clot can form. If that clot reaches the lung — which is called a pulmonary embolism — it is a serious emergency. The act of walking activates the calf muscles. Every time Sebastián takes a step, those muscles contract and push blood toward the heart. That movement is the protection.)
“¿Y el tercero?” Ernesto asked. (And the third?)
“El intestino. La anestesia suprime el sistema nervioso del intestino — el intestino tiene sus propios nervios que coordinan el movimiento que mueve los alimentos a través de él. La anestesia los duerme. Los calmantes basados en morfina — que tratamos de evitar exactamente por esto — también frenan el intestino. Y la manipulación quirúrgica, aunque mínima en una laparoscopia, también reduce temporalmente el movimiento intestinal. Cuando el intestino está frenado, el gas y los líquidos se acumulan, Sebastián no puede expulsar gas ni ir al baño, el abdomen se distiende, y la recuperación se prolonga. Caminar — estar en posición vertical — activa el reflejo gastroсólico: el intestino grueso responde a la postura erguida y al movimiento del cuerpo activando sus propias contracciones. El tiempo hasta la primera expulsión de gas, hasta el primer movimiento intestinal, y hasta que Sebastián pueda comer de nuevo — todo eso se reduce si camina hoy en vez de mañana.” (The bowel. Anesthesia suppresses the nervous system of the bowel — the bowel has its own nerves that coordinate the movement that moves food through it. Anesthesia puts them to sleep. Morphine-based pain relievers — which we try to avoid precisely for this reason — also slow the bowel. And surgical manipulation, even if minimal in a laparoscopy, also temporarily reduces bowel movement. When the bowel is slowed, gas and liquid accumulate, Sebastián cannot pass gas or have a bowel movement, the abdomen distends, and recovery is prolonged. Walking — being in an upright position — activates the gastrocolic reflex: the large intestine responds to upright posture and body movement by activating its own contractions. The time to the first passage of gas, to the first bowel movement, and to when Sebastián can eat again — all of that is reduced if he walks today instead of tomorrow.)
Ernesto sat back. He looked at Sebastián. Sebastián was watching his father’s face, waiting.
“¿Y el dolor?” Ernesto asked. “Si duele, ¿no empeora algo?” (And the pain? If it hurts, doesn’t it worsen something?)
“El dolor al moverse viene de las incisiones y de la inflamación alrededor de donde estuvo el apéndice. Ese dolor es real y lo manejamos — le acabamos de dar acetaminofén y ketorolaco, que son antiinflamatorios que alivian el dolor sin frenar el intestino como la morfina. El dolor al caminar no hace daño a las incisiones — las incisiones están cerradas y no se van a abrir por caminar. Lo que caminar hace es mover los músculos de la pared abdominal, y eso duele porque los músculos están sensibles. Es real. Pero el daño que evitamos al caminar — la pulmonía, el coágulo, el intestino parado — es mayor que el dolor de la caminata. Por eso lo hacemos.” (The pain from moving comes from the incisions and from the inflammation around where the appendix was. That pain is real and we manage it — we just gave him acetaminophen and ketorolac, which are anti-inflammatories that relieve pain without slowing the bowel like morphine. The pain of walking does not harm the incisions — the incisions are closed and will not open from walking. What walking does is move the muscles of the abdominal wall, and that hurts because the muscles are sensitive. It is real. But the damage we prevent by walking — pneumonia, a clot, a stopped bowel — is greater than the pain of the walk. That is why we do it.)
Ernesto stood up. He was a tall man, and he moved to stand beside Sebastián’s bed. “Sebastián,” he said. “Escuchaste al enfermero. Los tres.” (Sebastián. You heard the nurse. All three.)
Sebastián winced but pushed himself up on his elbows. “¿Me ayudas, papá?” (Will you help me, dad?)
“Siempre.” Ernesto put out a hand and helped his son sit upright at the edge of the bed. (Always.)
Valeria watched as Sebastián’s feet touched the floor. He breathed carefully, adjusting. Then he straightened and took a step. The IV pole moved with him. Ernesto walked on one side, the nurse on the other. They reached the hallway threshold before Sebastián stopped, breathing evenly, and said he wanted to turn back.
“Perfecto,” Valeria said. “Esto es exactamente lo que necesitábamos. Lo haremos de nuevo en dos horas.” (Perfect. This is exactly what we needed. We will do it again in two hours.)
Scenario 3: Valentina Cruz-Mendoza — 6 years old, Dallas, Texas
Valentina Cruz-Mendoza had arrived at the pediatric emergency department by ambulance on a Thursday morning at 8:15 AM with sudden-onset diffuse abdominal pain, bilious vomiting, and an abdomen that was rigid on palpation. She had been entirely well the previous evening. She was six years old, previously healthy, and had no surgical history. An urgent abdominal X-ray showed a paucity of distal bowel gas and a “double-bubble” sign in the mid-abdomen. A CT angiogram of the abdomen confirmed midgut volvulus from intestinal malrotation: the entire small bowel had rotated 360 degrees around the superior mesenteric artery axis, compromising the blood supply to the small intestine. The pediatric surgery team took Valentina to the operating room emergently within 34 minutes of the CT result.
Intraoperatively: midgut volvulus reduced by counter-clockwise rotation (Ladd procedure); approximately 35 centimeters of small bowel from the distal jejunum that showed no return of viability after 20 minutes of warm saline compresses was resected; primary anastomosis performed with 4-0 PDS suture; Ladd’s bands divided; appendix removed. Estimated blood loss 80 mL. The remaining small bowel — the majority of it, all of the ileum, and the jejunum proximal to the resection — demonstrated brisk return of viability with pink tissue and visible peristalsis after reduction of the volvulus. The anastomosis was under mild tension. The surgeon noted in the operative report: “bowel rest recommended for minimum 5 days; total parenteral nutrition to be initiated post-operatively via surgically placed central venous line.”
Valentina was moved to the pediatric intensive care unit post-operatively, then transferred to the surgical floor on post-operative day two, where her clinical status had improved: she was afebrile, hemodynamically stable, NGT output was bilious but decreasing, and the surgical team was cautiously optimistic about the anastomosis. The TPN was running through a right femoral central venous catheter at 62 mL per hour.
Valentina’s grandmother, Lucía Cruz-Mendoza, had driven from Fort Worth when she received the call. Lucía was 68 years old and had worked for 30 years as a cafeteria worker in the Fort Worth Independent School District — she knew food and she knew children, and she had sat beside Valentina’s bed for thirty-eight hours without going home. She was the kind of presence that filled a room with a quiet, fundamental authority.
She was also confused in a way that had been building since she arrived, and on the morning of post-operative day two she asked the nurse directly.
“Me dijeron que no se puede comer ni beber nada porque el intestino necesita descansar,” Lucía said. She gestured at the large bag hanging from the IV pole — a white opaque bag labeled “TOTAL PARENTERAL NUTRITION,” with several smaller bags of additives attached to the tubing. “Y al mismo tiempo, están dando eso. Que dice nutrición. Si el intestino descansa, ¿por qué se está alimentando? No entiendo.” (They told me she cannot eat or drink anything because the bowel needs to rest. And at the same time, they are giving that. Which says nutrition. If the bowel is resting, why is it being fed? I do not understand.)
Post-operative nurse Carolina Espinoza-Villanueva had been waiting for this question. She sat down across from Lucía in the room’s family chair.
“Es exactamente la pregunta correcta, y tiene una respuesta que cambia todo cuando se entiende. Voy a empezar por lo que significa ‘descanso del intestino,’ porque creo que la confusión está ahí.” (That is exactly the right question, and it has an answer that changes everything when you understand it. I am going to start with what ‘bowel rest’ means, because I think the confusion is there.)
Lucía folded her hands in her lap and waited.
“El intestino de Valentina es un tubo largo. Cuando comemos, los alimentos entran por la boca, bajan por el esófago, pasan por el estómago, y después pasan por el interior del tubo del intestino — que se llama la luz del intestino — mientras el intestino digiere y absorbe los nutrientes. El cirujano cortó una parte de ese tubo que no sobrevivió y unió los dos extremos cortados. Esa unión — que se llama anastomosis — está en el interior del tubo del intestino. Está todavía muy nueva. Las células están creciendo para unir los dos bordes.” (Valentina’s bowel is a long tube. When we eat, food enters through the mouth, goes down the esophagus, passes through the stomach, and then passes through the inside of the bowel tube — which is called the bowel lumen — while the bowel digests and absorbs the nutrients. The surgeon cut a part of that tube that did not survive and joined the two cut ends. That union — called an anastomosis — is inside the bowel tube. It is still very new. Cells are growing to join the two edges.)
“El descanso del intestino significa que nada — ni comida, ni agua, ni líquidos, nada — pasa por el interior del tubo en el lugar donde está esa unión. ¿Por qué? Porque si algo pasa por ahí antes de que las células hayan unido los dos bordes, puede pasar una de dos cosas muy malas. La primera: la presión del líquido pasando puede separar los bordes antes de que estén soldados — romper la unión. La segunda: el intestino normalmente tiene miles de millones de bacterias viviendo adentro, en los desechos que viajan por el tubo. Si la unión se rompe, esas bacterias salen del tubo y entran a la cavidad del abdomen — y eso causa una infección grave que se llama peritonitis. Por eso el intestino descansa: para que el tubo no tenga nada pasándole por dentro en ese lugar, y la unión pueda curarse sin presión ni bacterias.” (The bowel rest means nothing — not food, not water, not liquids, nothing — passes through the inside of the tube at the place where that union is. Why? Because if something passes through there before the cells have joined the two edges, one of two very bad things can happen. The first: the pressure of the liquid passing through can separate the edges before they are fused — break the union. The second: the bowel normally has billions of bacteria living inside, in the waste matter that travels through the tube. If the union breaks, those bacteria exit the tube and enter the abdominal cavity — and that causes a serious infection called peritonitis. That is why the bowel rests: so that the tube has nothing passing through it at that point, and the union can heal without pressure or bacteria.)
Lucía was following, her eyes on the nurse. “¿Y mientras tanto?” (And in the meantime?)
“Las células que están curando esa unión — y todas las demás células del cuerpo de Valentina — necesitan azúcar, proteínas, y grasa para funcionar. Las células no pueden esperar cinco días sin nutrición. Sin nutrición, el cuerpo comienza a degradar los propios músculos y el tejido graso para sacar energía. En un niño que acaba de tener una cirugía de emergencia, eso retarda la curación y aumenta el riesgo de infección. Así que la pregunta es: ¿cómo le damos a Valentina toda la nutrición que sus células necesitan sin poner nada por dentro del tubo del intestino?” (The cells that are healing that union — and all the other cells in Valentina’s body — need sugar, proteins, and fat to function. Cells cannot wait five days without nutrition. Without nutrition, the body begins to break down its own muscles and fat tissue for energy. In a child who has just had emergency surgery, that slows healing and increases the risk of infection. So the question is: how do we give Valentina all the nutrition her cells need without putting anything inside the bowel tube?)
“Por la vena,” Lucía said slowly. She was beginning to see it. (Through the vein.)
“Por la vena. Ese,” Carolina said, gesturing to the white bag on the IV pole, “tiene cuatro cosas. La primera es dextrosa — que es azúcar en una forma que puede ir directamente a la sangre, la energía que las células necesitan para hacer su trabajo. La segunda son aminoácidos — los bloques de construcción de las proteínas. Las células que están curando la unión del intestino necesitan proteínas para construir tejido nuevo. La tercera es emulsión lipídica — grasa en unas partículas tan pequeñas que pueden entrar a la vena, para dar energía adicional y las vitaminas que son solubles en grasa. Y la cuarta son minerales, vitaminas, y oligoelementos — todo lo que el cuerpo necesita en cantidades pequeñas para que los sistemas funcionen bien. Todo eso va directamente a la sangre. De la sangre va a todas las células del cuerpo, incluyendo las células que están curando la anastomosis. Esas células reciben todo lo que necesitan. Y el interior del tubo del intestino — donde está la unión — no recibe nada. No hay presión. No hay bacterias. Descansa.” (Through the vein. That,) — (has four things. The first is dextrose — which is sugar in a form that can go directly to the blood, the energy the cells need to do their work. The second is amino acids — the building blocks of proteins. The cells healing the bowel union need proteins to build new tissue. The third is lipid emulsion — fat in particles so small they can enter the vein, to provide additional energy and the fat-soluble vitamins. And the fourth is minerals, vitamins, and trace elements — everything the body needs in small amounts for systems to work well. All of that goes directly to the blood. From the blood it goes to all the cells in the body, including the cells healing the anastomosis. Those cells receive everything they need. And the inside of the bowel tube — where the union is — receives nothing. No pressure. No bacteria. It rests.)
Lucía was quiet for a moment. She looked at the bag on the IV pole, then at Valentina, who was asleep. Then she looked back at the nurse.
“Entonces la nutrición por la vena no va al intestino,” she said. “Va directo a la sangre, como si fuera lo que el intestino normalmente hace después de digerir la comida. El intestino descansa porque no tiene que tocar nada. Las células de Valentina reciben todo lo que necesitan para curar por afuera.” (So the nutrition through the vein does not go to the bowel. It goes directly to the blood, as if it were what the bowel normally does after digesting food. The bowel rests because it does not have to touch anything. Valentina’s cells receive everything they need to heal from the outside.)
“Exactamente eso,” Carolina said. “Y cuando el ciru jano vea que la unión está lo suficientemente curada — lo vamos a evaluar cada día — vamos a empezar a agregar líquidos claros por la boca, muy poco a poco. La nutrición por la vena va bajando a medida que Valentina tolera más por la boca, hasta que el intestino esté listo para hacer todo el trabajo solo otra vez.” (Exactly that. And when the surgeon sees that the union is healed enough — we will evaluate it every day — we are going to start adding clear liquids through the mouth, very gradually. The IV nutrition decreases as Valentina tolerates more through the mouth, until the bowel is ready to do all the work on its own again.)
Lucía nodded slowly. She reached over and adjusted the blanket across Valentina’s feet. “Gracia,” she said, quietly. “Ahora tiene sentido.” (Thank you. Now it makes sense.)
