全身麻醉誘導(dǎo)期呼氣末正壓通氣對子宮肌瘤患者腹腔鏡術(shù)后呼吸功能的影響
[Abstract]:Objective to investigate the effect of positive end-expiratory pressure on respiratory function in patients with hysteromyoma during induction of general anesthesia (general anesthesia). Methods from January 2011 to January 2014, 200 patients with hysteromyoma underwent laparoscopic hysterectomy were selected and divided into control group and observation group. The patients in the control group were treated with positive end-expiratory pressure ventilation (PEEP),) during operation, and the patients in the observation group received positive end-expiratory pressure ventilation (PEEP).) at the beginning of anesthesia induction period during operation. The hemodynamic parameters, respiratory parameters, arterial blood gas changes and respiratory compliance were observed and recorded in the two groups during perioperative period. Results the difference of arterial and end-expiratory carbon dioxide pressure (Pa-ETCO_2) during pneumoperitoneum 30 minutes, pneumoperitoneum 60 minutes, pneumoperitoneum 90 min and exhalation was significantly lower in the observation group than at the time of pneumoperitoneum, and the levels were compared with those in the control group. The dynamic compliance of pneumoperitoneum, pneumoperitoneum and pneumoperitoneum in the observation group was significantly higher than that in the control group at 30 minutes, 60 minutes and 90 min, respectively, and the dynamic compliance of alveoli in the observation group was significantly higher than that in the control group (P 0.05). The difference between the two groups was statistically significant (P 0.05). Conclusion positive end-expiratory pressure ventilation during induction of general anesthesia has a good preventive effect on hypoxemia and hypercapnia in patients with uterine leiomyoma after general anesthesia, and can reduce the incidence of atelectasis. It is worth popularizing in clinic.
