We report the results of a study of the effects of spinal and epidural anaesthesia for Caesarean section on commonly used indicators of a patient's ability to cough effectively. Both spinal and epidural anaesthesia, after the achievement of a block adequate for surgery, were associated with statistically significant decreases (p less than 0.05) in all the respiratory variables recorded: forced vital capacity, forced expiratory volume in one second, peak expiratory flow rate and maximum expiratory pressure. We conclude that although the observed changes are unlikely to impair the normal patient's ability to cough effectively in these circumstances, there may be clinically significant impairment in the presence of an inadvertently high block or in a patient with pre-existing pulmonary disease.
我们报告了一项关于剖宫产脊髓麻醉和硬膜外麻醉对患者有效咳嗽常用指标影响的研究结果。在达到足以进行手术的阻滞水平后，脊髓麻醉和硬膜外麻醉均与所有记录的呼吸变量出现具有统计学意义的下降（p小于0.05）相关：用力肺活量、一秒用力呼气量、呼气峰值流速和最大呼气压力。我们得出结论，虽然在这些情况下观察到的变化不太可能损害正常患者有效咳嗽的能力，但在无意中出现高平面阻滞或存在既往肺部疾病的患者中，可能会出现具有临床意义的损害。
