ObjectiveTo explore the effect of timely adjustment of carbon dioxide(CO₂) pneumoperitoneum pressure on the comfortableness and surgical effect of patients in total laparoscopic hysterectomy.

MethodsA total of 60 patients with total laparoscopic hysterectomy were selected as the research objects.All patients were randomly divided into experimental group and control group according to the random number table method, with 30 cases in each group.In the experimental group, the pneumoperitoneum pressure was set at 14 mmHg from the beginning of operation to before the hysterectomy, then the pressure was reduced to 10 mmHg after hysterectomy, and maintained this pressure until the end of the operation.In the control group, the pneumoperitoneum pressure was set to 14 mmHg after the establishment of pneumoperitoneum, and the pressure remained unchanged during the operation until the end of the operation.The time of suture of vaginal stump and peritoneal suture, the score of shoulder pain by visual simulation within 24 h after surgery, the length of hospital stay and the score of intraoperative visual field exposure were compared and analyzed.

ResultsThe time of suture of vaginal stump and peritoneum, shoulder pain score within 24 hours and hospital stay in the observation group were significantly lower than those in the control group(P < 0.01).There was no significant difference in the intraoperative visual operative field exposure score between the two groups(P>0.05).

ConclusionsIn total laparoscopic hysterectomy, the pneumoperitoneum pressure should be adjusted first to 14 mmHg to remove the affected uterus, and then the pneumoperitoneum pressure should be lowered to 10 mmHg, which can shorten the suture time and improve patient comfort, shorten hospital stay and promote patient recovery.
