摘要
目的比较小口径气管导管间歇正压通气 (IPPV)和高频喷射通气 (HFJV)在支撑喉镜术中的通气效果。方法择期支撑喉镜下声带息肉摘除术病人 30例 ,ASAⅠ~Ⅱ级 ,随机分为IPPV组(Ⅰ组 )和HFJV组 (H组 )各 15例 ,两组均插入内径 5 5mm或 6 0mm气管导管 ,分别于麻醉前 ,通气 5、10、15、2 0分钟采集动脉血作血气分析。结果H组术中PaCO2 明显升高 (P <0 0 1)并产生高碳酸血症 ;I组术中PaCO2 无明显变化 (P >0 0 5 ) ,两组术中PaO2 均明显升高 (P <0 0 1)。结论HFJV和IPPV都能满足对机体的供氧 ,但HFJV易导致二氧化碳蓄积 ,IPPV则能保证呼吸 ,安全可靠。
Objective To compare the effects of the intermittent positive pressure ventilation(IPPV) with the high frequency jet ventilation(HFJV) during suspension laryngoscopy.Methods 30 ASA grade Ⅰ~Ⅱ patients with phonatory bands papilla were scheduled for selective suspension laryngoscopy.The patients were randomly divided into two groups:IPPV group(group I, n =15) and HFJV group(group H, n =15).Both groups were inserted I.D.5.5 mm or 6.0 mm tracheal tube.Before anesthesia and 5,10,15 and 20 min after starting ventilation,arterial blood samples were collected respectively for blood gas analysis. Results The PaCO 2 increased significantly( P <0 01)and hypercapnia occurred in group H,the PaCO 2 didn't increase( P >0 05) in group I,the PaO 2 of both groups increased significantly( P <0 01)during the ventilation.Conclusion Both HFJV and IPPV can meet the need of oxygen delivery,but HFJV leads easily to hypercapnia.IPPV was safe and reliable to use in suspension larygoscopy.
