Benign prostatic hyperplasia is common in elderly males, and this group of patients is commonly associated with different comorbidities especially of the cardiovascular system , this make them at risk of many intraoperative complications. The associated adverse effects arising in both the cardiovascular and nervous systems are known as transurethral resection (TUR) syndrome.Therefore TURP patients need meticulous monitoring of hemodynamics and fluid therapy.~This study is designed to investigate the relevance of the timing of hypertonic saline administration either as a preload or as a coload on hemodynamic parameters in patients undergoing TURP surgeries.~100 ASA physical status I-III male patients scheduled to electively undergo transurethral resection of the prostate under spinal subarachnoid block were included in this study~Preload group (Group P):~50 Patients will receive 4 ml/kg of hypertonic saline (NaCL3%) via G14 cannula over 15-20 min before the induction of spinal anaesthesia.~Co-load group (Group C):~50 Patients will receive 4 ml/kg of hypertonic saline (NaCL3%) via G14 cannula at the maximal possible rate at the time of identification of C.S.F .
