【摘要】 为观察开胸术后应用椎旁胸膜外神经阻滞对呼吸功能的影响。本文选择100例择期开胸患者,随机分为止痛组和对照组,每组各50例。止痛组于术后采用持续椎旁胸膜外神经阻滞。结果:开胸术后,止痛组每分通气量（MV）、血氧饱和度（SpO₂）均明显高于对照组（P<0.01）;呼吸频率（RR）明显较对照组慢（P<0.01）。止痛组无一例肺部并发症,对照组则发生3例肺部并发症,其中1例为呼吸衰竭。结论:椎旁胸膜外神经阻滞能有效地促进开胸术后呼吸功能的恢复,改善术后低氧血症,减少肺部并发症的发生。更多还原

【Abstract】 In order to observe the effect of continuous paravertebral extrapleural nerve block(CPENB) on respiratory function. 100 patients with elective thoracotomy were randomely divided into the analgesia group and the controlled group-group A and group C. Each group consisted of 50 cases. Group A was administrated CPENB on postoperation. The results indicated that the VAS of group A was significantly lower than that of group C(P<0.01). The MV and SpO2 of group A were significantly higher, the RR of it was significantly slower than those of group C after thoracotomy. There was no pulmonary complications in group A, while there were 3 cases in group C. It is concluded that CPENB can effectively promote the recovery of pulmonary function,improve the hypotonic hypoxia and reduce the pulmonary complication.更多还原
