Abstract:
Objective To evaluate the effect of facemask ventilation with different pressures on perioperative complications in the patients undergoing gynecological laparoscopic surgery. Methods Seven-ty-five American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients of both sexes, aged 18-60 yr, with body mass index of 18-24 kg∕m2 , scheduled for elective gynecological laparoscopic surgery under general anesthesia, were divided into 3 groups ( n=25 each) using a random number table method: 10 cmH2 O group ( group P10) , 15 cmH2 O group ( group P15) and 20 cmH2 O group ( group P20) . The pres-sure for facemask ventilation was 10, 15 and 20 cmH2 O during induction of anesthesia in group P10, group P15 and group P20, respectively. Before facemask ventilation ( T0 ) and at 180 s of facemask ventilation ( T1 ) , longitudinal and anteroposterior diameters of the antral area in the supine position were measured u-sing ultrasonography, the antral cross-sectional area was calculated, and the development of serious flatu-lence was recorded. The development of hypoxemia, tidal volume and end-tidal pressure of carbon dioxide in each group were recorded at T1 . The operation time and occurrence of postoperative flatulence and nausea and vomiting were recorded. Results Compared with group P10, the incidence of serious flatulence and postoperative flatulence and nausea and vomiting was significantly increased, and the incidence of hypox-emia was decreased in group P15 and group P20, and tidal volume was increased at T1 in group P20 ( P<0. 05) . Compared with group P15, the incidence of serious flatulence was significantly increased ( P<0. 05) , and no significant change was found in the incidence of hypoxemia and postoperative flatulence and nausea and vomiting in group P20 ( P>0. 05) . There was no significant difference in the end-tidal pressure of carbon dioxide at T1 or antral cross-sectional area at T0 and T1 among the three groups ( P>0. 05) . Con-clusion Pressure of 10-15 cmH2 O for facemask ventilation is optimal during induction of general anesthe-sia and can ensure adequate oxygen supply and reduce perioperative complications in the patients undergoing gynecological laparoscopic surgery.
