采用联合同步间歇指令通气（ＳＩＭＶ）和压力支持通气（ＰＳＶ）方式抢救１１例格林－巴利综合征（ＧＢＳ）呼吸衰竭患者。通气前：ｐＨ为７．２２±０．０８，ＰａＣＯ＿２为８．０２±０．５２ｋＰａ（６０．３０±３．９１ｍｍＨｇ），ＰａＯ＿２为６．０６±０．２５ｋＰａ（４５．５６±１．８８ｍｍＨｇ）；联合通气后：ｐＨ为７．３９±０．０４（Ｐ＜０．０５），ＰａＣＯ＿２为５．５４±０．３１ｋＰａ（Ｐ＜０．０１），ＰａＯ＿２为９４０±０．２６ｋＰａ，（Ｐ＜０．０１）。心电图Ｓ－Ｔ段及Ｔ波异常明显好转。治愈９例，好转２例。结果表明：ＳＩＭＶ和ＰＳＶ联合运用能改善患者有效通气而不增加呼吸功，减少因机械通气而发生的氧中毒和呼吸性碱中毒，对循环系统无损害作用。
Eleven patients with GBS respiratory failure were treated with systolic synchronized intermittent inspiratory ventilation (SIMV) and pressure support ventilation (PSV). Before ventilation, pH was 7.22 ± 0.08, PaCO_2 was 8.02 ± 0.52kPa (60.30 ± 3.91mmHg), PaO_2 was 6.06 ± 0.25kPa (45.56 ± 1.88mmHg) (P <0.05); PaCO_2 was 5.54 ± 0.31 kPa (P <0.01); PaO 2 was 940 ± 0.26 kPa (P < 0.01). Electrocardiogram S-T segment and T wave abnormalities significantly improved. 9 cases were cured, improved in 2 cases. The results showed that the combination of SIMV and PSV can improve the effective ventilation of patients without increasing the work of breathing, reduce the oxygen poisoning and respiratory alkalosis caused by mechanical ventilation, and have no damage to circulatory system.
