Abstract:
Objective To observe oxygenation status when different modes of mechanical ventilation were actualized during laparoscopic operations in obese patients. Methods Sixty obese patients for laparoscopy were divided into three groups with 20 patients in each group, receiving volume controlled ventilation (VCV Group), or pressure controlled ventilation (PCV Group), or pressure controlled ventilation with positive end-expiratory pressure (PCV+PEEP Group). Levels of pH value, PCO_2, PO_2/FiO_2, and Qs/Qt were measured at 30 min after pneumoperitoneum (T1), 60 min after pneumoperitoneum (T2), 30 min after extubation (T3), and 60 min after extubation (T4), respectively. Results The oxygenation index was significantly higher in the PCV+PEEP Group at T1 (429.35?51.88) and T4 (231.87?20.47) than in the VCV Group at T1 (346.15?54.48; q=6.771, P
