Abstract :

Objective: To study efficacy of Thoracic Paraverteal Block (TPVB) with 0.125% Bupivacaine by Catheter Technique for Postoperative Analgesia in Breast Surgery. Methods: This randomized controlled trial was conducted in females admitted in surgery wards for east surgery of any type in the age group of 18–60 years, in tertiary care hospital in Western Maharashtra in India. Period of study was from January 2008 to December 2009. After obtaining informed consent and informing Visual analogue scale (VAS), cases were enrolled in two groups A and B. Sample size was 30 in each group. Group A received Thoracic paraverteal block by catheter technique with 0.125% Bupivacaine 15 ml single infusion and group B received intra muscular Diclofenac Sodium 75 mg single dose towards end of surgery. Results: In group A at the end of 1st hour mean Visual Analogue Scale (VAS) was 0 and in group B it was 0.233 with Standard Deviation (SD) of 0.678 with p value of 0.04 which is statistically significant. At the end of 5th hour mean VAS in group A was0.266 and in group B it was 1.13 with SD of 1.43 and p value of 0.007 which is statistically significant. Conclusions: Thoracic Paraverteal Block (TPVB) with 0.125% Bupivacaine by catheter technique is more efficacious than intramuscular Diclofenac Sodium for postoperative analgesia in east surgery.
