Complications of Umbilical Vein Catheterization: Neonatal Total Parenteral Nutrition Ascites After Surgical Repair of Congenital Diaphragmatic Hernia By Britt Nakstad, Pål Aksel Naess, Charlotte de Lange, and Ole Schistad Oslo, Norway

A 2-day-old girl was admitted to surgery for repair of a left-sided diaphragmatic hernia (CDH). Preoperatively, an umbilical vein catheter (UVC) was inserted with the tip in the left hypochondrium. The UVC tip position was unchanged radiographically peroperatively. At the fifth postopertive day abdominal distension and signs of gastric outlet obstruction appeared. Explorative laparotomy found

NSERTION OF UMBILICAL vein catheters (UVCs) is a commonly used procedure for intravenous access in neonatal intensive care units (NICUs). The UVC facilitates the administration of parenteral nutrition and intraveneous medication and blood sampling. The use of UVC, however, may cause complications such as infection,1 thrombus formation,1,2 and catheter tip migration.3,4 We report a case of total parenteral nutrition (TPN) ascites 5 days after surgical closure of a left-sided congenital diaphragmatic hernia (CDH). CASE REPORT

In a newborn girl, born at the 36th gestational week, birth weight 2,300 grams, a left-sided CDH had been diagnosed prenatally by ultrasound scan. Postpartum chest x-ray showed the stomach and intestine in the left hemithorax and a mediastinal shift to the right indicating a left diaphragmatic hernia. She was given surfactant and was ventilated by high-frequency oscillation for 2 days until pulmonary vascular resistance was normalized. A UVC was placed below the diaphragm at the level of the 11th thoracic vertebra (T11) with the tip in the left hypochondrium (Fig 1A). On the second postnatal day the girl was admitted for surgical repair of the CDH. Parts of the left hepatic lobe, the stomach, small and large intestine, and the spleen were found herniated into the left hemithorax. All organs were returned into the abdominal cavity before the diaphragmatic defect was closed. The UVC location was unchanged (Fig 1b). Postoperatively, the patient needed ventilatory support. TPN was given through the UVC from the second postoperative day. Hyperglycemia developed, and she was given insulin repeatedly. Feeding through a nasogastric tube was unsuccessful because of increasing aspirate volumes. Abdominal distension and radiologic signs of gastric outlet obstruction (Fig 2) led to relaparotomy. The peritoneal cavity was filled with TPN ascites, and a focal necrosis on the lower surface of the left liver lobe was found. Bolus infusion of saline through the UVC immediately leaked out from this necrotic area. Postoperatively, intestinal obstruction developed, and a third laparatomy was performed in the third postoperative week for release of intestinal adhesions. Eight days after the last operation, all nutrients were given orally, and the further course was uneventful. She was Journal of Pediatric Surgery, Vol 37, No 8 (August), 2002: E21

DISCUSSION

In the current case, abdominal distension and signs of gastric outlet obstruction occurred shortly after surgical repair of CDH. Surprisingly, explorative laparotomy showed massive TPN ascites. Leakage from the tip of an UVC through a focal necrosis in the left liver lobe had led to the extravasation of TPN fluid. To our knowledge, this is the first report of TPN ascites in a neonate occurring shortly after major abdominal surgery. Before repair of the diaphragmatic defect, herniated abdominal organs, including part of the left liver lobe, were returned to the abdominal cavity. The tip of the UVC, tightly secured at skin level, might have perforated the liver parenchyma during this procedure. Alternatively, hypertonic solutions, like TPN, may produce focal hepatic damage.5-7 TPN ascites as a complication of UVC is rare with only 10 patients reported.5,8,9 In contrast to the current case, the majority of those babies were preterm with birth weight less than 1,500 g, and none had a history of previous surgery. The preferred position of the UVC tip is at or above the diaphragm in the inferior vena cava, which may be difficult to obtain, especially in CDH patients because of liver displacement. A subdiaphragmatic UVC can be accepted. In the current case, the UVC tip was at the From the Departments of Pediatrics, Pediatric Surgery, and Pediatric Radiology, Ullevaal University Hospital, Oslo, Norway.

level of T11 (Fig 1A and B), indicating intrahepatic location. Seguin et al10 reported a 92% initial success rate for UVC placement, but only two thirds were reported to be above the diaphragm. Greenberg et al11 showed that two thirds of UVC tips located at T10 were found to be within the liver, whereas all tips located from T7 to T9 radiographically were positioned within the right atrium or inferior vena cava. Our case, after abdominal surgery and TPN therapy, illustrates that the use of of an subdiaphragmatically located UVC is associated with the risk of vascular perforation. Signs of abdominal distension in newborns receiving hyperosmolar fluid therapy through an UVC may be associated with liver necrosis and subdiaphragmatic vein perforation ultimately leading to TPN ascites.
