Abstract

Inguinal hernia repair (IHR) is a common surgical procedure which can be performed under general, regional, or peripheral nerve block anesthesia. Subarachnoid block is the most commonly used modality for IHR. Even with experience, unilateral paravertebral block (PVB) as a primary anaesthetic modality is under-utilized. As a result, this study was conducted to compare the safety and effectiveness of PVB with subarachnoid block (SAB) for inguinal hernia repair surgeries. Methods: The study comprised patients ranging from 18 to 65 years of age. They were randomly assigned to groups P and S of 30 participants each. A two-segment paravertebral block was given at T10 and L1 in Group P and patients in Group S were given spinal anaesthesia. Results: The onset of sensory blockade, time taken for first rescue analgesia, time for ambulation and hemodynamic responses showed a statistically significant difference between the two groups (p 0.001). In group S, urinary catheterization was more frequent (p 0.05), whereas no patients in group P required catheterization. Conclusion: Paravertebral block performs better than spinal anaesthesia for unilateral inguinal hernia repair in terms of prolonged analgesia, early ambulation, and a decrease in spinal anaesthesia-related complications.
