Here's an explanation of gastroschisis: 1. Definition of gastroschisis Gastroschisis is a birth defect where the intestines and sometimes other abdominal organs protrude through a hole in the abdominal wall, usually to the right of the umbilical cord. The exposed organs are not covered by a protective sac. 2. Predisposing factors Predisposing factors include young maternal age (especially under 20), maternal smoking, maternal recreational drug use (e.g., cocaine), and possibly certain maternal infections or medication use during early pregnancy. 3. Causes The exact cause of gastroschisis is largely unknown (idiopathic). It is thought to result from a disruption in the blood supply to the developing abdominal wall during early fetal development, leading to a failure of the abdominal wall to close completely. It is generally not genetic. 4. Pathophysiology During embryonic development, the abdominal wall fails to fuse, creating a defect, typically to the right of the umbilicus. This allows the intestines and sometimes other organs to herniate outside the abdominal cavity. Unlike omphalocele, there is no protective sac, so the exposed organs are directly bathed in amniotic fluid. This exposure can cause inflammation, thickening, and damage to the bowel, leading to issues like malabsorption and dysmotility after birth. 5. Diagnosis Prenatal diagnosis: Most cases are detected during routine ultrasound scans in the second trimester, showing bowel loops floating freely in the amniotic fluid outside the fetal abdomen. Elevated maternal serum alpha-fetoprotein (MSAFP)* levels can also be an indicator. Postnatal diagnosis*: The condition is immediately visible at birth, with the intestines protruding from the abdominal wall. 6. Management Prenatal: Regular ultrasound monitoring* is crucial. Delivery is typically planned at a specialized center, often at term (37-39 weeks). Postnatal (Surgical): Immediately after birth, the exposed bowel is protected with a sterile, moist dressing and plastic wrap. Surgical repair is the definitive treatment. This may involve primary closure (returning the bowel and closing the abdominal wall in one surgery) or staged closure using a silo (a prosthetic sac) to gradually reduce the bowel into the abdomen before final closure. Intravenous fluids and antibiotics are administered, along with Total Parenteral Nutrition (TPN)*. 7. Nursing management Pre-operative*: Protect the exposed bowel with sterile, warm, saline-soaked gauze and plastic wrap. Maintain the infant's body temperature, administer IV fluids, insert an orogastric (OG) tube for decompression, and administer antibiotics. Provide emotional support to parents. Post-operative*: Manage pain, monitor for respiratory distress, maintain fluid and electrolyte balance, continue TPN until enteral feeds can be gradually introduced, prevent infection, and monitor bowel function and the surgical wound. 8. Complications Potential complications include bowel damage/dysfunction (leading to malabsorption, ileus, or short bowel syndrome), infection (sepsis), necrotizing enterocolitis (NEC), intestinal atresia or stenosis, feeding difficulties, respiratory compromise after closure, and long-term issues like adhesions or bowel obstruction. 9. Prevention Gastroschisis is largely not preventable as its exact cause is unknown. However, avoiding known risk factors such as maternal smoking and recreational drug use during pregnancy can help reduce the likelihood. Early and regular prenatal care is also important for monitoring. That's 2 down. 3 left today — send the next one.
