Non-invasivebloodpressureandheartrate(HR)wereobservedat baseline and at 2 minute intervals following spinal injection for the first15minutesandat5minuteintervalsthroughouttherestofsurgery. Baseline, highest and lowest values of systolic blood stress (SBP)andHRwerenoted.Hypotensionwasdefinedasadecrease ofSBP30 ofbaselineor90mmHgafterspinalinjection.Hypotensive episodes have been treated with an improved rate of crystalloid infusion. If D3 Receptor drug hypotension persisted within the second consecutive measurement, a bolus of ephedrine five mg was administered. Bradycardia was definedasaheartrate(HR)oflessthan60beatsperminute(bpm) and was planned to be treated having a 0.5 mg atropine bolus. The numberofhypotensiveepisodes,totalamountoffluidsadministered,median ephedrine consumption and quantity of individuals requiring ephedrine inside the operating space till the finish of surgery have been recorded. The incidence of side effects such as shivering, nausea, vomiting and pruritus throughout the study period have been noted. There is absolutely no comparable study in the literature to supply a reference for sample size calculation. We assumed that a minimum difference that will be clinically important will be 60 min amongst the groups.StudiesontheeffectofIVorneuraxiallyappliedmagnesium onspinalanaesthesiareportedawiderangeofvariancefortimetofirst analgesicrequest(Apanetal.(3),Unlugencetal.(15),Yousefetal.
