Local Anaesthesia Versus Spinal Anaesthesia in Inguinal Hernia SurgeryAn Evidence Based Approach

Abstract

Introduction: This article outlines comparative analytical data obtained by inguinal surgeries performed under local and spinal anaesthesia to develop a precise opinion regarding both techniques. Aim: To formulate an ideal, safe combination of anaesthesia (local versus spinal) for inguinal hernia surgeries in terms of minimizing pain, hospital stay and recovery period. Materials and Methods: This prospective analytical study was conducted on 140 patients of uncomplicated unilateral inguinal hernia which were operated after dividing them in two groups on the basis of type of anaesthesia (Local anaesthesia or Spinal anaesthesia) received. Outcome of study was compiled and statistically analysed for cost benefit, patient satisfaction levels, intra and postoperative complications. Results: The mean age of patients under study was 44.36±23.31 years in group A and 40.44±18.36 years in group B. Difference in the median time taken for surgery in both groups (70.26 vs 72.46 min) was not statistically significant (p-value>0.05). Postoperative complications were comparable in both groups except spinal anaesthesia related complications. Pain relief was better in local anaesthesia group in the initial 24 hours. Median postoperative hospital stay was less (2.36 days versus 3.56 days) in local anaesthesia group. Median time for returning to work in group A was less as compared to group B (8 days vs 11 days). Conclusion: Inguinal hernia repair under local anaesthesia is a reliable, safe and cost effective technique. In India, where patients load out numbers available resources and expertise, use of this technique will increase performance of surgery both in quantity and quality
