目的:探讨持续口腔内低负压吸引在冠状动脉搭桥术后机械通气时的应用价值。方法:对2016年1月至2016年4月260例非体外循环下冠状动脉搭桥手术患者,术后返回监护室后,常规给予持续口腔内低负压吸引,与2015年同期162例非体外循环下冠状动脉搭桥术后的患者作回顾性分析比较。结果:治疗组术后肺部并发症较去年同期明显减少。同时护理工作量明显少于对照组,差异具有统计学意义(P<0.05)。结论:对行冠状动脉搭桥术经口气管插管机械通气的患者,术后给予持续口腔内低负压吸引,可以降低隐性误吸的发生率,降低吸入性肺炎的发生率及死亡率,降低住院花费,同时减少护理工作量。 Objective: To investigate the value of continuous low oral suction in mechanical ventilation after coronary artery bypass graft surgery. Methods: From January 2016 to April 2016, 260 patients undergoing coronary artery bypass graft without cardiopulmonary bypass were returned to the intensive care unit after operation and were routinely given low intraoral vacuum suction. Compared with 162 non-cardiopulmonary bypass Patients undergoing coronary artery bypass grafting were retrospectively analyzed and compared. Results: The postoperative pulmonary complications in the treatment group decreased significantly compared with the same period of last year. At the same time, the nursing workload was significantly less than that of the control group, the difference was statistically significant (P <0.05). CONCLUSIONS: Patients undergoing mechanical ventilation through the tracheal intubation undergoing coronary artery bypass grafting under continuous low intraoral vacuum suction can reduce the incidence of asymptomatic aspiration and reduce the incidence and mortality of aspiration pneumonia, Reduce hospital costs, while reducing the workload of nursing.
