Effects ofpneumoperitoneum on the airway pressure and pulmonary infection of patients with different body mass index in laparoscope / 临床麻醉学杂志

ABSTRACT

Objective To make clear the patients in minimally invasive surgery through explo-ring effects of pneumoperitoneum and pulmonary infection on the airway pressure of patients with dif-ferent body mass index (BMI)under general anesthesia.Methods A total of 849 cases of patients with trachea cannula in pneumoperitoneum surgery inr general anesthesia under different position were studied.To observe the changes of airway pressure and the ratio of pulmonary infection within one week of patients in general anesthesia.Propofol,Remifentanil and Atracrium were used in general an-esthesia.BIS and TOF were used to detect the degree of muscle relaxation.Results The airway pres-sure was increased obviously in patients of Head-down Tilt under same pneumoperitoneum pressure(P30 kg/m2 (P 30 kg/m2 under same pneumoperitoneum pressure.Therefore,shorten the operation time and decreased pneumoperitoneum pressure could be used to prevent pulmonary infection.
