Abstract:

Objective

To investigate the efficacy and safety of hemostatic powder used in total knee arthroplasty (TKA).

Methods

A prospective randomized cohort study was used in this study.A total of 213 patients (213 knees) with knee osteoarthritis who underwent TKA for the first time in the joint surgery Department of Xuzhou Renci Hospital from January 2023 to November 2023 were included. Patients with coagulation dysfunction and anemia [hemoglobin(Hb)<90 g/L]were excluded. The enrolled patients were randomly divided into two groups by envelope method: the experimental group (98 patients received hemostatic powder) and the control group (115 patients did not receive hemostatic powder). Hb was detected before surgery,one day and three days after surgery, and the total blood loss, intraoperative blood loss and hidden blood loss were compared between the two groups. Blood transfusion rate, incidence of DVT, occurrence of superficial skin infection, and gender were compared by chi square test. T test was used to compare operative time,intraoperative blood loss, occult blood loss, total blood loss, Hb, age, and body mass index (BMI).

Results

The Gross and Nadler equations were used to calculate blood loss in both groups. The total blood loss of the experimental group was (627.0±92.9) ml, which was less than (815.5±142.4) ml of the control group (t=11.224,P<0.001). The hidden blood loss of the experimental group was (530.5±78.6) ml, which was less than (693.4±120.8)ml of the control group (t=11.450, P<0.001). The hemoglobin in the experimental group was higher than that in the control group at one day and three days after operation (t=4.771,7.070, both P<0.05).There was no statistically significant difference in intraoperative blood loss, operation time, blood transfusion rate, postoperative LHS,superficial skin infection rate or incidence of DVT between the two groups (all P>0.05).

Conclusion

Hemostatic powder can reduce perioperative blood loss without increasing complications during total knee arthroplasty.
