ABSTRACT
Objective To evaluate the effects of negative pressure suction liquid collector in patients undergoing percutaneous endoscopic interlaminar discectomy.Methods Fifty patients undergoing percutaneous endoscopic interlaminar discectomy from October 2015 to August 2016 were chosen as the control group,while 50 patients receiving the same surgery from September 2016 to February 2017 were chosen as the experimental group.The experimental group was treated with negative pressure suction liquid collector,and the control group was treated with conventional drainage procedure.Water pollution of surgical drape,operator gown and operating room floor,and workload of operating room personnel were evaluated,and rate of intraoperative hypothermia was compared between two groups.Results There were only 3 cases of operator's splashed sleeves in the experimental group,and the water pollution rate of surgical drape,operator gown and operating room floor in the control group was 100％,and the difference was statistically significant (P＜0.01).The workload of circulating nurses for cleaning wet floor and operation assistants for sucking liquid in the experimental group was reduced by 100％ compared to the control group (P＜0.01).The rate of intraoperative hypothermia was 4％ in the experimental group and 22％ in the control group,and the difference was statistically significant (P＜0.05).Conclusion Application of negative pressure suction liquid collector for percutaneous endoscopic interlaminar discectomy can significantly reduce the workload of operating room personnel and pollution of operating room,and the rate of intraoperative hypothermia.
