Background and Aims: Thoracotomy incision following patent ductus arteriosus (PDA) ligation surgery is often associated with severe post-operative pain that has deleterious effects on respiratory function. We aimed to assess pain relief with thoracic paravertebral block using either bupivacaine or ropivacaine in these surgeries. Methods: One hundred paediatric patients of age group between 2 and 10 years undergoing PDA ligation surgery were randomised either to bupivacaine or ropivacaine group in this prospective double-blinded study. After induction of general anaesthesia, the ultrasound-guided paravertebral block was carried out using 0.25% bupivacaine 0.4 ml/kg in Group B patients and 0.2% ropivacaine 0.4 ml/kg in Group R patients. Monitoring included minimum mandatory monitoring with pulse rate, pulseoximetry (SpO 2 ), electrocardiogram, blood pressure, temperature during surgery and also in Intensive Care Unit (ICU). Additionally, modified objective pain score (MOPS) was used in ICU for assessment of pain for 12 h after surgery. Incidence of complications was noted. Results: Mean values of MOPSs were comparable in both the groups. The time to rescue analgesic was 8 to 10 h in over 80% of patients in both the groups. More patients had hypotension and bradycardia in bupivacaine group compared to ropivacaine group. Conclusion: Paravertebral injection of 0.4 ml/kg of either 0.2% ropivacaine or 0.25% bupivacaine provided equipotent analgesia, but ropivacaine had a better side effect profile. Ultrasound-guided paravertebral block is a safe and effective mode of analgesia in paediatric patients undergoing thoracotomy.
