Objective:To observe the effect of laryngeal mask general anesthesia with autonomous breathing on the rehabilitation of patients undergoing removal of thoracic internal fixation device. Methods: The patients who underwent thoracic internal fixation under endotracheal intubation combined with general anesthesia in Maoming people's Hospital from January 2019 to January 2020 were selected as the control group(43 cases), and the patients who retained spontaneous breathing laryngeal mask general anesthesia in our hospital from January 2020 to January 2021 were selected as the experimental group(43 cases), Including open reduction and internal fixation of rib and sternal fractures and minimally invasive correction of funnel chest and chicken chest. The differences of general operation, postoperative recovery and inflammatory indexes between the two groups were compared. Results: There was no difference in anesthesia preparation time and operation time between the two groups. The lowest intraoperative blood oxygen saturation(SpO2) level in the experimental group was slightly better than that in the control group, but the difference was not statistically significant; The postoperative recovery time and postoperative hospital stay in the experimental group were shorter than those in the control group. The score of visual analogue scale(VAS) of pain 24 hours after operation was lower than that in the control group, the difference was statistically significant(P<0.05); The postoperative leukocyte count, C-reactive protein, procalcitonin and interleukin-6 water were significantly lower than those in the control group(P<0.001); Postoperative blood glucose and tumor necrosis factor- α The level was lower than that in the control group(P<0.001); The incidence of restlessness, urinary retention, respiratory secretion and throat pain were lower than those in the control group(Fisher* <0.001).Conclusion: The application effect of thoracic internal fixation device removal under general anesthesia with autonomous breathing laryngeal mask is good, which can inhibit postoperative inflammatory reaction, reduce postoperative complication rate and promote rehabilitation process. It has clinical application value. |
