Comparison of Paravertebral Block with Spinal Anaesthesia in Unilateral Inguinal Hernia Repair

Aims Comparison paravertebral block with subarachanoid block in unilateral inguinal hernia repair. Objective Evaluation of efficacy of spinal anaesthesia & Paravertebral block in unilateral inguinal hernia repair with respect to postoperative analgesia, ambulation, perioperative and postoperative complication. Method Sixty (ASA) I-II patients between 18-60 years with unilateral inguinal hernia were enrolled for study, and statistical analyses was done. Patients were randomly divided into two groups, with 30 patients in each Group S, spinal anaesthesia and Group P, paravertebral block. Standard monitoring was done, and mean arterial pressure and heart rate were recorded during the procedure. Demographic variables, surgical data, patient satisfaction, the onset time to reach T10 dermatome to reach peak sensory level, & modified Bromage 3 motor block recorded. Postoperative nausea, vomiting and pain at postoperative hours 0-24 with visual analog scale measured. Results Compared to pre- anaesthesia measurements, decrease in HR and MAP during 10th-90th minute was significant in Group S In Group P, sensory block duration time was higher, whereas motor block was higher in Group S. In Group P there was a need to supplement Inj. Propofol, due to partial or inadequate block. Bromage scores were significantly different between the groups. Time required and drug volume to achieve block was higher in Group P Conclusion Subarachnoid block is better than Paravertebral block for unilateral inguinal hernia surgery in terms of time required for performing the procedure, efficacy, patient comfort & surgeons satisfaction.
