目的为减少经皮冠状动脉成形术(PCI)术后拔管出现的迷走反射。方法将88例行PCI术的冠心病患者随机分为间断拔管组及常规拔管组,其中间断拔管组46例,均采用每次拔出2～3 cm,暂停30～60 s。观察术后迷走反射发生情况。结果间断拔管组无一例出现迷走反射,而常规拔管组有3例发生,占7.14%,两者差异有统计学意义(P<0.01)。结论间断拔管法可显著减少PCI术后拔管出现的迷走反射。
The purpose is to reduce vagal reflexes occurring after extubation of percutaneous transluminal coronary angioplasty (PCI). Methods Eighty-eight patients with coronary artery disease undergoing PCI were randomly divided into intermittent extubation group and conventional extubation group, of which 46 cases were interrupted extubation group, each of which was withdrawn 2 ~ 3 cm and suspended for 30-60 s. Observe the occurrence of postoperative vagal reflex. Results There was no vagal reflex in the intermittent extubation group, while there were 3 cases in the conventional extubation group (7.14%), the difference was statistically significant (P <0.01). Conclusion Intermittent extubation can significantly reduce the vagal reflex after extubation of PCI.
