【Objective】 To discuss the risk factors for postoperative hemorrhage in acute postoperative hypertensive patients after tumorectomy. 【Methods】 The clinical data of 528 patients receiving tumorectomy

which happened postoperative hypertension were analyzed retrospectively. 【Results】 The incidence of postoperative hemorrhage was 12.1%. The univariate analysis showed that the major prognostic factors for postoperative hemorrhage were sex(P = 0.001)

smoking (P = 0.020)

operative time (P = 0.012)

operative type (P = 0.003)

and diastolic blood pressure level when hypertension was treated (P = 0.005). Multivariant analysis show that only the operative time was identified as the independent risk factor associated with the occurrence of postoperative hemorrhage (P=0.040). 【Conclusions】 The blood pressure level when hypertension was treated may be not related with postoperative hemorrhage

whereas the operative time may be related with postoperative hemorrhage in postoperative hypertensive patients.
