七氟醚诱导下斑马导丝管芯胃管置入的观察

Observation of gastric intubation with zebra- guidewire under the induction of anesthesia with sevoflurane

目的探讨七氟醚麻醉诱导下胃管置入以及将斑马导丝作为胃管管芯的可行性（斑马导丝选用泌尿外科经皮肾镜手术后废弃的导丝）。方法将需要留置胃管的40例患者随机分成实验组和对照组各20例，实验组在七氟醚吸入全麻下斑马导丝引导下胃管置入；对照组按常规置入胃管。比较2组置管过程中生理指标的变化情况、不良反应的发生率及一次置管成功率和人均置管时间。结果实验组置管前和置管时的血压、心率等生理指标比较无显著波动，而对照组血压和心率波动明显。置管时的不良反应发生率、一次置管成功率、平均置管时间实验组均显著优于对照组，差异有统计学意义。结论七氟醚麻醉诱导下置胃管是一种理想的无痛苦置胃管操作方法。斑马导丝管芯胃管在麻醉状态下置入简单、快捷。

Objective To investigate the practicability of gastric intubation with zebra-guidewire under the induction of anesthesia with sevoflurane （zebra-guidewire was the obsolete guide wire in percutaneous nephrolithotomy in urology surgery）. Methods The patients who needed gastric intubation were randomized into the experimental group and the control group with 20 patients in each group, the experi- mental group received gastric intubation with zebra- guidewire under the induction of anesthesia with sevoflurane. In the control group, the gastric tubes were catheterized with routine method. The physiological indices changes, incidence rate of adverse reaction and success rate of one-time catheterization and average time of catheterization per patient were compared between the two groups. Results In patients of the ex- perimental group, the blood pressure, heart rate before and during the intubation did not fluctuate evidently, but in the control group the results were the opposite. In the experimental group the incidence rate of ad- verse reaction, success rate of one-time catheterization and average time of catheterization per patient were superior to the control group. Conclusions Gastric intubation under the induction of anesthesia with sevoflurane was a painless way of gastric intubation. Gastric intubation with zebra-guidewire under anesthe- sia state was simple and fast.
