Aims and Objectives: The purpose of the study is to prospectively evaluate. 1.The feasibility and efficacy of bilateral continuous Paravertebral block for off pump coronary artery bypass surgery. 2.Time taken for extubation following cardiac surgery. 3.Hemodynamic parameters. Methodology: This was a prospective randomised study which included 60 patients, 30 each in Group A (PVB) and 30 patients in Group B (control). Group A had catheter inserted on either side of the spine in the paravertebral space at T3- T4 or T4-T5 level and a bolus of 0.25 mlkg[sup -1] Inj Bupivacaine 0.25% was given followed by an infusion of Inj Bupivacaine 0.125% at the rate of 0.15 mlkg[sup -1] hr[sup -1] throughout the surgery and continued postoperatively. In Group B Inj Fentanyl 1|jgkg[sup -1]hr[sup 1] IV infusion was given intraoperatively and Inj Tramadol 1mg/kg TID IV post operatively. Parameters evaluated included hemodynamic parameters, visual analogue scale pain score (pain severity- 0-3=mild, 4-7=moderate, >7=severe) at rest and deep breathing, rescue analgesia at 0 hr, 4 hr, 8 hr, 12hr, 24hr and 36 hr, ICU and hospital stay. Unpaired t-test and chi-square test were used to compare values between 2 groups. Results: The severity of pain in group B was statistically significant at 0 and 8hr at rest and statistically significant at 0, 8, 12 and 24hr with deep breathing as compared with Group A. A less requirement of rescue analgesia was observed in Group A vs Group B (0.27+/- 0.72 vs 2.0+/-0.926). Group A had more stable haemodynamic parameters in post-operative period. Compared with the group B, the length of ICU and hospital stay in group A was numerically lower but not statistically significant (p=0.439 and p=0.560, respectively). Conclusion: Bilateral continuous Paravertebral block is feasible, provides good hemodynamic stability, excellent analgesia and allows early extubation. [ABSTRACT FROM AUTHOR] |
