A COMPARATIVE STUDY OF MEDIAN AND PARAMEDIAN TECHNIQUES TO IDENTIFY THE LOWER THORACIC EPIDURAL SPACE AND CATHETER INSERTION FOR UPPER ABDOMINAL SURGERIES
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2017, Vol 6, Issue 95
Abstract
BACKGROUND Epidural is a central neuraxial blockade with various applications. The epidural space was first described by Corning in 1901. And Fidel Pages first used epidural analgesia in humans in 1921. Fidel Pages described the interspinous approach to the epidural space and reported satisfactory anaesthesia for abdominal procedures. Improvements in equipment, drugs and technique have made it a popular and versatile anaesthetic technique, with applications in Surgery, Obstetrics and Pain relief. Both single injection and catheter techniques can be used. Its versatility means it can be used as an anaesthetic, an adjuvant to general anaesthesia and for postoperative analgesia in procedures involving the lower limbs, perineum, pelvis, abdomen and thorax. This study compares the median and paramedian epidural techniques to identify the lower thoracic epidural space and catheter insertion for upper abdominal surgeries. METHODS AND MATERIALS This is a comparative, randomised, double-blinded prospective study comparing median and paramedian approaches to identify the lower thoracic epidural space and catheter insertion for upper abdominal surgeries in two groups of patients comprising of fifty patients each. The observations were analysed using Epi info software and ANOVA measure for students’ test and Chi-square test to compare the data between the two groups. RESULTS This study shows paramedian approach of identification lower thoracic epidural space has less number of attempts, less incidence of dural tap, easy insertion of catheter, less incidence of pain, less time taken to identify the epidural space and less resistance to catheter insertion than the median approach. CONCLUSION The location of epidural space in patients posted for upper abdominal surgeries was found to be easier and has lesser complication by paramedian approach when compared to median epidural approach.
