Effectiveness Of Epinephrine With Intrathecal Lidocaine For Spinal Anesthesia On Onset Time Of Sensory Block And Total Analgesia Consumption At Alert Referral Hospital Addis Abeba Ethiopia2019.

Introduction: Spinal anesthesia is one of the most popular and widely used anestheticrnprocedures. Different techniques used widely to fasten the onset and to prolong the duration andrnincrease the quality of analgesia of Neuraxial block. Currently epinephrine appears promising inrninfluencing onset and duration of local anesthesia.rnof 0.2mg of Epinephrine to 5% Lidocaine is effective both to shorten onset of the block andrnprolong duration of analgesia with additional incentives of decrease total analgesia consumption.rnObjective: to assess Effectiveness of epinephrine with intrathecal Lidocaine for spinalrnanesthesia on onset time of sensory block and total analgesia consumption at ALERT referralrnhospitalrnMethodology: a hospital based cohort study was conducted at ALERT hospital from October 14Novembrrnrn15, 2019 on 44 ASA class I and II patients whose age above 18 undergoing electivernlower abdominal surgery by using systematic random sampling method. Onset of the block,rnduration of analgesia, analgesia requestand total analgesia consumption were assessed.rnDistribution of numerical data analyzed using Shapiro Wilk test then after Mann Whitney U testrnwere used to compare asymmetric data. Independent t-test was used to compare mean values ofrnsymmetric data. Categorical variable between two groups were analyzed using Chi Square. prnvalue of
