Abstract:
OBJECTIVE: To identify the factors to transurethral resection of prostate (TURP) perioperative hypotension. METHODS: The study group included 130 patients undergoing TURP. The control group included 50 patients who had suprapubic prostatectomy. Absorption of irrigation fluid was measured by determining the serum gentamycin level. Blood loss of PURP patients was calculated as the product of the irrigation fluid volume and hemoglobin concentration (determined with a photometer) divided by the preopreative blood hemoglobin concentration. Body temperature was recorded using a rectal probe. Serum electrolytes were determined pre-and postop. RESULTS: The blood loss in study group (380.2+/-98.3)ml was significantly less than in the control group (460.1+/-52.5)ml, P<0.05. However, the incidence of hypotension was significantly higher than the control group 28%, 8%), P<0.01. Factors associated with TURP hypotension included volume of irrigation fluid absorption, blood loss, reduction in core temperature, decrease of serum sodium, operating time, prostate weight and volume and history of cardiovascular disease. After Logistic regression analysis, the most significant factors were excessive absorption of irrigation fluid and rapid central cooling. CONCLUSION: In our study TURP hypotension most closely correlated with volume of irrigation fluid absorbed and reduction in core temperature.
