Spinal Versus Local Anesthesia for Hernia Repair

Overview

patients underwent inguinal hernia repair; Group A patients received Subarachnoid anesthesia; Group B Patients underwent surgery with local anesthesia (Mepivacaine 2%) performed by the surgeon; Pain assessment was performed using a 0-10 Numerical Rating Scale (NRS). Intraoperative pain was assessed every 10 minutes,

All patients underwent inguinal hernia repair with the Trabucco's technique (15), performed by the same surgical team. Every patient was adequately informed of the procedural sequence of anesthesia and surgery and signed informed consent before being enrolled in the study. For both groups, patients received mild sedation with Midazolam 0.03 mg/kg i.v.; Paracetamol 1 gr and Ketorolac 30 mg i.v. were given before surgery as multimodal pre-emptive analgesia. Group A Subarachnoid anesthesia was performed with a 27G Whitacre needle at L2-L3 interspace, with patients on the lateral decubitus corresponding to the side of surgery. The introducer was inserted in the middle point of the space between two spinous processes, with a slightly cranial direction. The spinal needle was passed through the introducer and advanced till the subarachnoid space was reached, as confirmed by cerebrospinal fluid outflow. Subsequently, 60 mg of Prilocaine 2% were administered in the subarachnoid space, with a low-flow injection technique and the needle bevel turned laterally towards the sloping surgical side. Lateral decubitus was maintained for at least 10 minutes (16). At 15 minutes from spinal anesthesia execution, and before surgery started, sensory and motor block were assessed by ice-test and numerical 0-3 Bromage Scale, respectively. Group B Patients underwent surgery with local anesthesia (Mepivacaine 2%) performed by the surgeon before skin incision. Further infiltrations of local anesthetic were ensured in case of pain during the surgery, for a maximum of 400 mg of mepivacaine. In case of uncontrolled pain, fentanyl 50 mcg i.v. was given for a maximum of two intraoperative administrations. If pain persisted, a deep sedation was performed with propofol continuous i.v. infusion. Pain assessment was performed using a 0-10 Numerical Rating Scale (NRS). Intraoperative pain was assessed every 10 minutes,
