BackgroundThe aim of this study was to evaluate pain and pulmonary function the first two days after abdominal and laparoscopic hysterectomy.MethodsWomen scheduled for abdominal hysterectomy were prospectively randomized to either laparoscopic (n=20) or abdominal (n=20) hysterectomy. Analgesics were self-administered by the patients by means of a programable infusion pump containing morphine. Postoperative pain was evaluated using a visual analog scale. Oxygen saturation was measured with an oxymeter. Pulmonary function was assessed using a peak flow meter measuring peak expiratory flow and a vitalograph measuring forced vital capacity and forced expiratory volume in one second.ResultsPain scores were lower after laparoscopic hysterectomy at the first (p<0.05) and second postoperative day (p<0.01). Lung function was impaired on days 1 and 2 postoperatively, measured as peak expiratory flow, forced vital capacity and forced expiratory volume in one second, in both groups compared to the preoperative values. The patients undergoing laparoscopic hysterectomy had less impairment of lung function measured by peak expiratory flow (p<0.01), forced vital capacity (p<0.05) and forced expiratory volume in one second (p<0.05) the first postoperative day compared to the patients undergoing abdominal hysterectomy. The second postoperative day differences between the groups remained for peak expiratory flow (p<0.05) and forced expiratory volume in one second (p<0.05).ConclusionsLaparoscopic hysterectomy results in less pain and less impairment of respiratory function compared to abdominal hysterectomy.
