In patients 70 years or older, pulmonary function tests were performed before and after abdominal surgery to correlate the results with the development of postoperative pulmonary complications which developed in 48% of these patients, compared to 15% in the control group. To predict the development ot PPC, preoperative analysis of the flow-volume curve is useful and 4 (V50-V25)/forced vital capacity is a valuable parameter for the analysis of the flow-volume curve. Postoperatively, pulmonary function was reduced and there was a delay in the restoration of pulmonary function in cases with postoperative pulmonary complications. The administration of appropriate analgesics may be useful to improve postoperative ventilatory disturbances.
在70岁及以上的患者中，腹部手术前后均进行了肺功能测试，以将结果与术后肺部并发症的发生情况相关联。这些患者中48%发生了术后肺部并发症，而对照组的这一比例为15%。为预测术后肺部并发症的发生，术前对流量-容积曲线进行分析很有用，4（V50-V25）/用力肺活量是分析流量-容积曲线的一个有价值的参数。术后，肺功能下降，术后发生肺部并发症的患者肺功能恢复延迟。给予适当的镇痛药可能有助于改善术后通气障碍。
