Abstract:
Objective To investigate effects of three types of mechanical ventilation on oxygenation status in laparoscopic gastric banding for the treatment of morbid obesity.Methods Twenty-four morbidly obese patients scheduled for laparoscopic gastric banding were divided into three groups.The Group A was given a tidal volume of 12 ml/kg and a respiratory rate of 10 times/min,the Group B,a tidal volume of 20 ml/kg and a respiratory rate of 10 times/min,and the Group C,a tidal volume of 12 ml/kg and a respiratory rate of 20 times/min,respectively.The measurement of arterial blood for pH value,PO2,PCO2,Plat Pressure,Peak Pressure,and AaDO2 was conducted before(T1) and after pneumoperitoneum(T2). Results After pneumoperitoneum,the Group B had significantly higher Plat Pressure(33.2?1.8 cm H2O) and Peak Pressure(36.3?1.6 cm H2O) than the Group A(Plat Pressure: 29.5?3.9 cm H2O,q=3.053,P
