Randomized Controlled Trial Clinical Trial
A prospective randomized study of abdominal aortic surgery without postoperative nasogastric decompression.
Nasogastric decompression following abdominal aortic aneurysmectomy or bypass, for 3-4 days, is a routine part of postoperative care in many centers. A prospective randomized study of 80 patients undergoing abdominal aortic surgery was performed in order to determine the necessity of prolonged nasogastric decompression. Patients were divided evenly between removal of the nasogastric tube upon tracheal extubation and retention of the tube until the passage of flatus. ⋯ There were no significant differences in any of the measured variables between the two groups. The length of hospital stay was similar in both groups and three patients in each group required a nasogastric tube or reinsertion of one. In conclusion, the routine postoperative use of nasogastric tubes for abdominal aortic procedures is unnecessary.

Acute renal insufficiency is a common complication after surgery for congenital cardiovascular defects in neonates and is associated with a high incidence of morbidity and mortality. The authors reviewed their experience with continuous venovenous haemofiltration in neonates and infants with acute renal insufficiency resulting from low cardiac output following cardiovascular surgery. Twelve critically ill patients with pharmacologically intractable fluid overload were treated with continuous venovenous haemofiltration over a period of 42 months. ⋯ No complications relating to continuous venovenous haemofiltration were evident during the treatment. The survival rate was 59% (seven of 12). Continuous venovenous haemofiltration is a valid and simple method for controlling fluid overload in neonates and infants with low cardiac output.
