应用同步间歇指令通气和呼吸末正压通气抢救危重哮喘

MECHARICAL VENTILATION PATTERN APPLIED IN MANAGEMENT OF PATIENTS WITH SEVERE ASTHMATIC ATTACK

目的 探讨应用同步间歇指令通气和呼吸末正压通气 (SIMV +PEEP)模式救治危重哮喘。方法 将 2 3例危重哮喘患者分为两组。治疗组 12例 ,通气模式SIMV +PEEP。对照组 11例 ,通气模式为SIMV ,同时监测两组上机前与上机后 2h、12h、2 4h动脉血气、气道峰值压 (PIP)、内源性呼吸末正压 (PEEPi)。结果 应用SIMV +PEEP比SIMV通气模式的患者酸中毒、缺氧、二氧化碳潴留明显改善 (P <0 .0 1) ,PIP和PEEPi明显降低 (P <0 .0 1)。结论 对危重哮喘患者早期使用SIMV +PEEP通气模式是安全、有效的 。

Objective\ To investigate the pattern of mechanical ventilation in the treatmen t of severe asthmatic attack.Methods 23 patients with severe asthmatic attack w ere given SIMV+PEEP and SIMV groups, two groups an tested by blood gas analyses, airway peak pressure,PEEPi in monitor pre-treatment and post-treatment 2 h,12 h,24 h.Results\ SIMV+PEEP groups were obviously alleviated in 24 h,acid intoxic tion,lack of oxygen,carbon dioxide retention,airway peak pressure and PEEPi t han SIMV groups. Conclusion\ The pattern of SIMV+PEEP mechanical ventilation is a safety effective method to treat primeval severe asthmatic attack.
