COMPARISON OF PAIN LEVELS AND DURATION OF ANALGESIA USING 0.5% BUPIVACAINE AND 0.5% ROPIVACAINE FOR LOWER ORTHOPAEDIC SURGERIES
Journal Title: Journal of Advanced Medical and Dental Sciences Research - Year 2017, Vol 5, Issue 7
Abstract
Background: Pain is considered fifth vital sign along with pulse , blood pressure, temperature and respiration . Satisfactory pain relief is essential not only to reduce the morbidity and suffering of patient but also to keep morale of patient high throughout operative and post operative period. Epidural anaesthesia is safe and advantageous technique associated with fewer postsurgical recovery complications, shorter hospital stay and consequently decreased health care costs. Furthermore epidural anaesthesia and analgesia have been associated with reduction in the incidence and severity of much perioperative physiological trepidations. The aim of present study is to comparison of pain levels and duration of analgesia using 0.5% bupivacaine and 0.5% ropivacaine for lower orthopaedic surgeries. Materials and methods: Present study was conducted in a prospective randomized manner on ASA Grade I & II patients in the age group of 20-50 years in the Department of Anaesthesiology, Gandhi Medical College and associated Hamidia Hospital ,Bhopal (M.P.) scheduled to undergo elective lower limb orthopaedic surgeries. 50 patients of ASA Grade I & II were included in the study. All patients were shown Visual Analogue Score (VAS) and were appraised about the test pre operatively. Pain was assessed using 10 cm VAS (where 0 represents no pain and 10 being maximum imaginable pain). Under all aseptic precautions, a lumber epidural catheter was placed in L2 -L 3 interspace via Touhey’s needle and syringe with loss of resistence technique. Onset of sensory blockade was noted in all the patients. Determination of onset of sensory block by done by touch and pin prick technique. All the data was recorded in tabulated form and analyzed by SPSS software. Chi square test was used for analysis. P value of greater than 0.05 was considered significant. Results: The age of the patients varied from 20 -50 years in the both age groups .The youngest was 20 years and the eldest was the 50 years. The mean age of the patients in Group I was 35.125 ± 7.4 years and in the Group II was 34.2± 9.0 years. The duration of complete analgesia in Group I was 257 +/-15.5 mins and in Group II it was 289±22.5.There was a significant difference in the duration of complete analgesia between the two groups. . In Group I ,72 %patients described analgesia to be excellent( VAS 0 to 3) while in Group 80 % patients described analgesia to be excellent. Conclusion: The duration of sensory blockade was longer than 0.75% Ropivacaine compared to 0.5% Bupivacaine when given via lumber epidural. This is evidenced by increased duration of complete and effective analgesia in range of 289±22.5 mins and 315±38.5 mins respectively for Ropivacaine 0.75% group
