The value of nasogastric tube decompression after elective abdominal operations was assessed in a randomised trial in which 97 patients were and 100 were not allocated postoperative nasogastric decompression. Only two patients in the latter group subsequently required decompression. There was no statistically significant difference in the incidence of mortality, complications (including vomiting) or time to return of intestinal motility between the two groups. There was a significantly higher incidence of sore throat (P less than 0.0001) and nausea (P less than 0.05) in patients who received nasogastric decompression. A postal questionnaire to 259 UK general surgeons (96% replied) revealed that postoperative nasogastric decompression was usually used by 92% of surgeons after a Polya gastrectomy, 72% after a small bowel anastomosis, 49% after a large bowel anastomosis and 20% after cholecystectomy. We conclude that such a routine is not justified and should be reserved for those patients developing specific complications.
在一项随机试验中，对择期腹部手术后鼻胃管减压的价值进行了评估。该试验中，97例患者被分配接受术后鼻胃管减压，100例患者未接受。后一组中只有两名患者随后需要减压。两组在死亡率、并发症（包括呕吐）发生率或肠道蠕动恢复时间方面无统计学显著差异。接受鼻胃管减压的患者中，喉咙痛发生率显著更高（P<0.0001），恶心发生率也显著更高（P<0.05）。向259名英国普通外科医生发放的一份邮政调查问卷（96%回复）显示，92%的外科医生在Polya胃切除术后通常使用术后鼻胃管减压，小肠吻合术后为72%，大肠吻合术后为49%，胆囊切除术后为20%。我们得出结论，这种常规做法不合理，应仅用于出现特定并发症的患者。
