一、材料和方法 4例患者均为老年男性,年龄60～68岁,病程10～30余年,有程度不等的心肺功能不全。本次因严重并发症(气胸、上腹部手术)诱发喘息加重,经综合治疗效果不佳,致呼衰急剧恶化,严重发绀,昏迷,抽搐,心律失常,呼吸不规则,呼吸暂停1例达12′,另1例呼吸心跳骤停,血压下降濒临死亡,行紧急抢救。经气管插管/切开清除分泌物后以103型麻醉机进行人工呼吸。再接KR_(?)型高频喷射呼吸(HFJV)机,驱动压0.8～1kg/cm~2,呼吸比1:2频率60次/分,于30′,60′时分别测血气,1～2小时后改间歇正压通气(1PPV),频率12～30次/分,其余参数不变,用后120′作血气分析,进行调整。
First, the material and methods 4 patients were elderly men, aged 60 to 68 years, duration of 10 to 30 years, ranging from varying degrees of cardiopulmonary dysfunction. The severe complication (pneumothorax, abdominal surgery) induced wheezing increased, the comprehensive treatment of poor results in a sharp deterioration of respiratory failure, severe cyanosis, coma, convulsions, arrhythmia, irregular breathing, apnea up to 12 cases Another case of respiratory arrest, blood pressure dying, emergency rescue. Tracheal intubation / incision to remove secretions after artificial anesthesia machine type 103 artificial respiration. (HFJV) machine, the driving pressure was 0.8 ~ 1kg / cm ~ 2, the respiratory rate was 1: 2, the frequency was 60 times / min, blood gas was measured at 30 ’and 60’ 2 hours later, intermittent positive pressure ventilation (1PPV), the frequency of 12 to 30 beats / min, the remaining parameters unchanged, with 120 after blood gas analysis, to be adjusted.
