Description
Summary:To compare the effects of laparoscopic and open surgical procedures on postoperative strength and respiratory mechanics. Prospective cohort study. Adult university hospital. Fifty-one women aged 21 to 62 years scheduled to undergo elective cholecystectomy or hysterectomy (or related procedures), otherwise in good health. Open or laparoscopic cholecystectomy or hysterectomy (or related procedures). Maximum voluntary handgrip strength (HGS), forced vital (VC), forced expiratory volume in 1 second (FEV1), and maximal inspiratory pressure (MIP) were each measured preoperatively and on the first postoperative morning. A visual analogue pain scale score was evaluated in relation to performance of the postoperative strength and respiratory measurements. VC, FEV1, and MIP, but not HGS, were decreased after surgery. Postoperative VC, FEV1, and MIP were lower after open procedures than after laparoscopic procedures and after cholecystectomy than after hysterectomy (all p < 0.001). Pain scores were lower after laparoscopic than after open procedures (p < 0.005) and could account in part for differences in postoperative respiratory mechanics. Cholecystectomy and hysterectomy do not result in generalized muscle weakness, unlike more major abdominal procedures. Postoperative alterations in respiratory mechanics are related to the site of the surgery, the use of an open versus a laparoscopic approach and postoperative pain.
