Introduction:Now a day's most of the urological operations including transurethral resection of prostate (TURP) are performed under sub-arachnoid block (SAB). SAB is gaining increase popularity and replacing general anaesthesia gradually. Advantages are virtual avoidance of risks of general anaesthesia, for example, gastric aspiration and difficult tracheal intubation and also TURP syndrome can not be diagnosed early, whereas SAB is very useful to diagnose early and potentially prevent the above mentioned problems. However, hypotension after SAB results from functional sympathetic devervation, not only of the arterial and arteriolar

All patients admitted to the Intensive Care Unit of BSMMU between January 2006 and December 2006 on whom data had been entered into the study. A total of 473 admissions with complete records were available. Hospital mortality was 60.6%. Nonsurvivors were older than survivors and had longer ICU stays. Patients admitted from wards had a higher mortality than patients from the operating room/ recovery or the emergency department. Thirty-four percent of patients were in the ICU for >2 days, and they accounted for nearly 81% of bed occupancy. Early identification of patients at risk, both before admission and after discharge from the ICU, may allow treatment to decrease mortality. Research and resources may be best directed at patients who die, despite a relatively low predicted mortality. Many patients die after discharge from ICU and this mortality may be decreased by minimizing inappropriate early discharge to the ward, by the provision of high dependency and step-down units, and by continuing advice and follow-up by the ICU team after the patient has been discharged.

Introduction:Anaesthesia may influence intraoperative bleeding in several ways both physiologically and pharmacologically. Elective hypotension is used to reduce operative blood loss especially in those operations like spine surgery 1 , middle ear surgery, cerebro-vascular surgery where even a small quantity of blood can obscure the operative field and make difficulties for the surgeon for a good proper surgery and prolong duration of operation 1 . Laryngoscopic stimulation of oropharyngeal structure may be an important factor in the haemodynamic stress response associated with tracheal intubation. 2 Original ArticleUse of labetalol and glyceryl trinitrate for induced hypotension in spine surgery-A comparative study
