We report the changes observed in a number of pulmonary function tests performed on 36 patients undergoing Caesarean section under spinal anaesthesia. The tests comprised peak expiratory flow, forced expiratory volume in one second, forced vital capacity, forced expiratory volume in one second to forced vital capacity ratio and the maximal mid-expiratory flow. Significant changes occurred that are consistent with a restrictive ventilatory defect. These changes persisted for four hours after the induction of spinal anaesthesia. Administration of 35% oxygen by facemask failed to change significantly fetal umbilical vein pH or partial pressure of oxygen.
我们报告了对36例在脊髓麻醉下接受剖宫产手术的患者进行的多项肺功能测试中观察到的变化。这些测试包括呼气峰值流速、一秒用力呼气量、用力肺活量、一秒用力呼气量与用力肺活量之比以及最大呼气中期流速。出现了与限制性通气缺陷一致的显著变化。这些变化在脊髓麻醉诱导后持续了四个小时。通过面罩给予35%的氧气未能显著改变胎儿脐静脉的pH值或氧分压。
