title: Evidence for early nasogastric tube removal after infrarenal aortic surgery: a randomized trial.
abstract: OBJECTIVE
  Nasogastric tube (NGT) decompression after abdominal surgery is still largely used to prevent nausea and vomiting. However, indications are based more on practice than on studies. Moreover, prolonged NGT decompression can lead to complications. In this prospective and randomized study, we evaluated the effects of early withdrawal of NGTs in patients undergoing surgery of the infrarenal aorta.
  
  
  METHODS
  Between October 2001 and May 2002, consecutive patients underwent scheduled infrarenal aortic operations. Patients were prospectively randomised into two groups: group 1, NGT maintenance until the passage of flatus; and group 2, NGT removal at the time of tracheal extubation. Preoperative and perioperative data were collected. The main end point was the occurrence of nausea and vomiting. Secondary end points were tolerance of NGT withdrawal and postoperative complications. Criteria were compared between groups by using Mann-Whitney or Fisher exact tests.
  
  
  RESULTS
  Forty-six patients underwent aortic operations. Six patients were subsequently excluded from the study. Of the 40 randomized subjects, 20 patients were included in each group. Preoperative and intraoperative data were similar in both groups. There was no statistical difference between groups regarding nausea and vomiting. In group 1, the occurrence of respiratory complications was more frequent compared with group 2 (5 vs 0 complications; P = .023). There was no significant difference in intensive care unit stay, but the hospital stay was shorter in group 2 (mean, 9 +/- 3 days vs 15 +/- 9 days; P = .016). There were no differences in other adverse events.
  
  
  CONCLUSIONS
  This study does not support a significant effect of early removal of NGTs on nausea and vomiting in patients undergoing open repair of the infrarenal aorta. However, these findings suggest that NGT maintenance increases the risk of respiratory complications and the length of hospital stay.
