Treatments
GA induced hypotension in geriatrics
Postinduction hypotension will be defined as either~* A 30% drop in SBP or 20% drop in MAP from baseline, or an absolute SBP of less than 90 mm Hg and MAP of less than 65 mm Hg within three minutes of general anaesthesia induction, every minute until 15 min after endotracheal intubation and before the start of any surgical manipulations.~* Since endotracheal intubation and direct laryngoscopy can generate sympathetic activation, which will change blood pressure, we decided to start haemodynamic monitoring three minutes post endotracheal intubation.~* If the MAP was less than 65 mmHg, a 250 ml crystalloid bolus will be administered and repeated as necessary.~* If hypotension persist after IV fluid bolus, ephedrine will be given by three milligrams.~At the end of surgery.
