Abstract Objective To analyze whether there is more bleeding in patients undergoing total knee arthroplasty (TKA) without using a tourniquet. The secondary objectives were to analyze the operative time, the length of hospital stay, the need for transfusion, and the complication rate. Methods The present is a retrospective study through the analysis of medical records.
The patients were divided into two groups:
TKA with and without the use of a tourniquet. Reductions in the levels of hemoglobin and packed cell volume 24 h and 48 h after surgery, the operative time, the length of hospital stay, the need for transfusion, and the rate of complications up to 6 months postoperatively were compared between the groups. Results During the period analyzed, 104 patients underwent TKA, and 94 were included in the study. There were no differences between the groups regarding the mean values of hemoglobin and packed cell volume before surgery (p = 0.675 and p = 0.265), 24 h (p = 0.099 and p = 0.563), and 48 h (p = 0.569 and p = 0.810) after the procedure. Neither were there differences between the groups in terms of the operative time and the length of hospital stay (p = 0.484 and p > 0.05). Moreover, there were no differences regarding the need for transfusion and the complication rate. Conclusion It is possible to forgo the use a tourniquet in TKA without a significant change in hemoglobin and packed cell volume levels 24 h and 48 h after surgery when compared with the group using a tourniquet. There were no significant differences in the total operative time, length of stay, need for transfusion, and complication rate.
Resumo Objetivo Analisar se há mais sangramento em pacientes submetidos a artroplastia total do joelho (ATJ) sem a utilização do torniquete. Os objetivos secundários foram analisar os tempos cirúrgico e de internação, a necessidade de transfusão e a taxa de complicações. Métodos Estudo retrospectivo por meio da análise de prontuários.
