BACKGROUNDHypertensive patients develop wide swings in blood pressure intraoperatively, especially after spinal anaesthesia. Long term antihypertensive agents can modify this effect by controlling blood pressure. This study was undertaken to evaluate the haemodynamic effect in hypertensive patients on regular treatment with calcium channel blockers and beta-blockers who are undergoing elective surgery under spinal anaesthesia and compared with normotensives.

ABSTRACT:Immune thrombocytopenia (ITP) in adults is a chronic disease resulting from increased platelet destruction and impaired platelet production. In patients with low platelet count perioperative bleeding is a major risk factor thus posing important surgical and anesthetic challenge.
