摘要
目的 探讨鼻罩通气在上腹部手术后的呼吸支持作用。方法 5 0例择期行上腹部手术病人 ,术前肺功能检查证实存在轻度中度阻塞性呼吸功能障碍 ,术后随机分成两组。 ( 1)对照组 :术后常规鼻导管吸氧 ;( 2 )鼻罩组 :术后即开始以鼻罩行压力支持通气。观察两组病人术后通气功能及血气变化。结果 术后早期给予鼻罩通气 ,病人的氧合优于对照组 ,Pa CO2 低于对照组 ,VC、FEV1 .0 % 及MMF均明显高于对照组。
Objective To evaluate the effect of nasal mask ventilation (NMV) on respiratory function in patients with chronic obstructive pulmonary disease (COPD) following upper abdominal surgery (UAS) Methods Fifty patients undergoing elective UAS,who suffered from COPD preoperatively,were randomized into two groups postoperatively:(1) control group:patients inspired oxygen by nasal tube conventionally and (2) nasal mask group:patients were ventilated by nasal mask in pressure support ventilation (PSV) mode We investigated the effects of NMV on ventilatory function and arterial blood gases of two groups Results NMV resulted in significantly better oxygenation and lower PaCO 2 (P<0 05) VC,FEV 1 0% and MMF reduced less in nasal mask group (P<0 05) Conclusion NMV is beneficial in COPD patients receiving UAS for improving respiratory function in early postoperative period
