The evaluation of pulmonary function and blood gas analysis in patients submitted to laparoscopic versus open nephrectomy

Background: The aim of this study was to assess the early postoperative pulmonary function and arterial blood gases in patients who have undergone open versus laparoscopic nephrectomy. Materials and Methods: Forty patients were randomly assigned to undergo laparoscopic (LN, n=20) or open nephrectomy (ON, n=20). Pulmonary function tests including forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), forced expiratory volume at 25% (FEF25), forced expiratory volume at 50% (FEF50), forced expiratory volume at 25% to 75% (FEF25–75), forced expiratory volume in 1 second (FIV...
