Comparison of segmental thoracic spinal anaesthesia and general anaesthesia in umbilical and supraumbilical hernia surgeries

Patients will be divided into 2 groups, Group S receiving Segmental Thoracic Spinal Anaesthesia and Group G receiving General Anaesthesia.

In Group S, the patients posted for elective umbilical and supraumbilical hernia surgeries, STSA will be given by a 25G Quincke’s Needle at T10 level with Injection 0.5% Isobaric Levobupicavaine 6.25 mg (1.25ml) with Injection Fentanyl 25 mcg administered at a speed of 0.2 ml/second. Sensory effect will be measured by pin prick method.

In Group G, the patients posted for both elective umbilical and supraumbilical hernia surgeries, after pre oxygenation with 100% oxygen for 3 minutes, injection Glycopyrrolate 2-4 mcg/kg, Injection Ondansetron 0.2 mg/kg, Injection Midazolam 0.1-0.2 mg/kg, Injection Fentanyl 1-2 mcg/kg, patients will be induced with Injection Propofol 2 mg/kg and Injection Atracurium 0.5-0.6 mg/kg. Anaesthesia will be maintained with Oxygen, Nitrous Oxide, Isoflurane and injection Atracurium 0.1mg/kg and Paracetamol 1 gm intravenously as required. After the completion of the said surgery, patients will be reversed with Injection Glycopyrrolate 0.01 mg/kg and Injection Neostigmine 0.05 mg/kg and extubated.

The hemodynamic parameters will be noted down at the time of injection (0 minutes), at 2 minutes, at 5 minutes, 10 minutes, 15 minutes, 30 minutes and 1 hour, 2 hour, 4 hour, 6 hour. VAS Scoring will be done postoperatively at 1 hour, 2 hour,4 hours, and 6 hours respectively. Time required opr rescue analgesia will be noted in both the groups. Perioperative complication will be noted and managed if any.
