Comparison Of Clinical Effects Of Early Drainage Tube Clamping After Total Hip Arthroplasty

Objective: To explore an effective drainage method that can reduce blood loss after total hip arthroplasty(THA)without affecting hip joint function recovery.Methods:120 patients with aseptic necrosis of the femoral head who underwent unilateral total hip arthroplasty for the first time in the Department of Joint Surgery,the First Affiliated Hospital of Anhui Medical University from October 2017 to October2019 were randomly divided into 4 groups,each group of 30 Example: Experimental group: The incision drainage tube was clamped immediately after operation for 2 hours(group A),4 hours(group B),and 6 hours(group C),and then opened for negative pressure drainage.The control group(group D)continued negative pressure drainage.The nodes and total incision drainage volume,hemoglobin(Hb)and hematocrit(Hct)at the first and third days after operation were recorded and collected in the four groups at different time points.Total blood loss during the operation,blood loss during the operation,dominant blood loss after the operation,hidden blood loss,the rate of allogeneic blood transfusion in each group,the number of dressing changes,the VAS score on the 1st,3rd,and 5th days after the operation,and the difference after the operation The Harris score of time and various postoperative complications and other clinical data were analyzed and compared using statistical methods.Results : Experimental group [Group A(clamping 2h),Group B(clamping 4h),Group C(clamping 6h)] Incision drainage in the first 8 hours after surgery,Total drainage in24 hours after surgery,Day 1 and Compared with the control group(group D),Hb andHct at 3 days,the degree of hemoglobin decrease at 24 hours after operation,the total blood loss during the perioperative period,the postoperative apparent blood loss,and the postoperative allogeneic blood transfusion rate were significantly different.There were no significant differences in the incision drainage volume,intraoperative blood loss,and hidden blood loss among the other four groups(P> 0.05).The VAS score control group on the first and third postoperative days was higher than the experimental group,the difference was statistically significant(P <0.05);the VAS score control group and the experimental group on the fifth postoperative day were not significantly different(P> 0.05).There was no significant difference in Harris scores between the four groups at different time points after surgery,and there was no statistical significance(P> 0.05).Postoperative complications: infection,deep vein thrombosis,poor incision healing,etc.There was no significant difference between the control group and the experimental group(P> 0.05),and for subcutaneous ecchymosis,the experimental group [group A(clamping 2h),B Group(clamping 4h),group C(clamping 6h)] were 2 cases,0 cases and 4 cases,respectively,the control group(group D)2 cases,there was no significant difference between the experimental group and the control group(P> 0.05).).Conclusion: Short clamping of drainage tube early after total hip arthroplasty can effectively reduce dominant blood loss after THA,relieve the early postoperative pain,and does not affect the rapid recovery of hip joint function.Immediate postoperative clamping for 4 h was better than 2h and 6h.
