DISEASES, INTRAOPERATIVE BLEEDING
Among the 80 patients initially included in the study, seven patients (three in the TN group and four in the TMH group) had unexpected surgical difficulties and were converted to open surgery, and one patient in the TN group with sustained hypotension and intraoperative bleeding of > 1500 mL was excluded. Therefore, a total of 72 patients (90%) completed the study. The CONSORT flow diagram is shown in Fig.
