目的：探讨改良气管插管后留置胃管的方法.方法：将296例气管插管后手术患者按手术日期(单、双日)随机分为对照组135例和试验组161例.对照组按传统方法置管，试验组予螺旋型鼻肠营养管引导钢丝引导置管，比较两组一次置管成功率情况、插管时间、术后并发症.结果：两组一次置管成功率、术后并发症发生率及插管时间比较，差异有统计学意义(P<0.01).结论：改良方法置管成功率高，操作方法安全方便、快捷，简便易行、操作时间短、并发症少，更适合气管插管后患者.% Objective :To investigate different methods of insertion of gastric tube after general anesthesia tracheal intubation.Methods :296 tracheal intubation patients were divided into two groups (control group of 135 and test group of 161) by random according to operation date (singular or even numbers). Control group accept troditional insertion of gastric tube while test group accept spiral naso intestinal feeding tube guide wire-guiding insertion of gastric tube. Compare the success tate,the time and postoperative complication of two groups.Results :There was a significant difference between two group (P<0.01), according to the success rate,postoperative complications and intubation time.Conclusion :Compared with the troditional method,improvement method (spiral naso intestinal feeding tube guide wire-guiding) have higher success rate,more safe and more simplicity,and less complication.So improvement method (spiral naso intestinal feeding tube guide wire-guiding) is more fit for patient after general anesthesia tracheal intubation.
