If 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 become treated with a 0.5 mg atropine bolus. The numberofhypotensiveepisodes,totalamountoffluidsadministered,median ephedrine consumption and quantity of sufferers requiring ephedrine within the operating room until the finish of surgery were recorded. The incidence of unwanted side effects which includes shivering, nausea, vomiting and pruritus throughout the study period were noted. There is absolutely no comparable study inside the literature to supply a reference for sample size calculation.
