Introduction: Paravertebral block is utilised as anaesthesia for surgical operations such as breast surgery, thoracotomy, inguinal hernia repair, renal surgery mostly in unilateral procedures, as well as in chest trauma (rib fracture) for pain relief.PVB has been demonstrated to be more beneficial than traditional spinal anaesthesia for inguinal hernia repair, in relation to early walking and improved postoperative pain ratings. Materials and Methods:The study was a controlled experiment that used a double-blind, randomised design. After receiving approval from the institutional ethical committee, a total of 60 male patients between the ages of 18 and 65, with ASA physical status 1 and 2, who were scheduled for elective unilateral hernia surgery, were chosen for the study. The patients were informed about the surgery and its potential complications, as well as the use of VAS rating during the preoperative evaluation. Participants were randomised at random to two groups, labelled P and S, using a sealed envelope procedure. They were then given one of two anaesthetic techniques: Paravertebral block (PVB) or Spinal anaesthesia (SA), depending on their group. Two segment block, T10 and L1, was administered as a para vertebral block. Result: The two groups were statistically similar in terms of age, weight, preoperative vital statistics, SBP, DBP, and SPO2. During the operation, the occurrence of low blood pressure and the use of medication to raise blood pressure was more common in group S, with 25 patients (50%), compared to no such occurrences in group P. The total amount of propofol consumed was greater in group P than in group S ( p< 0.001). The VAS score reached its peak at 6 hours for group P (p < 0.001) and at 4 hours for group S (p < 0.001). The significance was observed at both 4 and 6 hours. At 12 and 24 hours, there was no noticeable distinction. The pain reliever Tramadol was administered intravenously in 50mg doses as needed when the pain score on the Visual Analogue Scale (VAS) was greater than 4. Conclusion:Paravertebral block can be utilised as a substitute for spinal anaesthesia in the surgical treatment of unilateral inguinal hernias. The effectiveness of this can be observed in improved management of blood flow, longer-lasting pain relief after surgery, absence of lingering muscle weakness, early ability to walk, and reduced occurrence of urine retention.
