Abstract:
Objective To investigate the effect and safety of topical tranexamic acid (TXA) plus cocktail analgesic for reducing blood loss during total knee arthroplasty (TKA).Methods A prospective case control study was made on 60 patients scheduled to undergo TKA because of knee injuries between August 2015 to June 2016.There were 13 males and 47 females,with the mean age of 65.5 years (range,51-80 years).Traumatic arthritis occurred in 44 patients and degenerative arthritis in 16 patients.The patients were assigned to separate cocktail analgesic group (Group A,n =30) and topical TXA plus cocktail analgesic group(Group B,n =30),according to the random number table.Patients in Group A received multiple-point intra-articular cocktail analgesic injection before implantation of the prosthesis in TKA.While patients in Group B received multiple-point intra-articular TXA plus cocktail analgesic injection before implantation of the prosthesis.Between-group differences were compared with respect to intraoperative blood loss,hemoglobin change (Hb),haematocrit (Hct),postoperative drainage,total blood loss,hidden blood loss,blood transfusion rate,Hospital for Special Surgery (HSS) score,incidence of deep venous thrombosis (DVT) and other complications.Results All patients were followed up for 3 months.Perioperative Hb reduction in Group B was 18.5 (13.0,26.0) g/L,less than 23.0 (21.0,35.5) g/L in Group A (P ＜ 0.05).Hct was reduced by 5.6 (4.1,7.8) ％ in Group B,while 7.2 (6.1,10.7) ％ in Group A (P ＜ 0.05).Postoperative drainage volume,total blood loss and occult blood loss in Group B were 105.0(60.0,223.8) ml,596.0(426.1,795.3) ml,422.3 (228.9,624.0) ml respectively,decreased compared to Group A [162.5 (118.8,245.0) ml,788.3 (583.0,1 082.4) ml,603.2 (435.2,884.7)ml respectively] (P ＜0.05).There were no significant differences in intraoperative blood loss,blood transfusion rate,HSS score and DVT incidence between the two groups (P ＞0.05).Conclusion Topical TXA plus cocktail analgesic can reduce blood loss during perioperative period in TKA,without increasing the risk of DVT.
