The patient will undergo conventional general anesthesia with a regimen of intravenous fentanyl 1-2 mcg/kg BW, propofol 2-3 ml/kg BW, and muscle relaxants for intubation, such as atracurium 0.5 mg/kg BW or rocuronium 0.6 mg/kg BB. After that the patient will be intubated

The patient will undergo epidural anesthesia first with an epidural catheter inserted through a Tuohy needle and ensuring that the length of the multihole epidural catheter that enters the epidural space is 5-6 cm. After that, the patient underwent conventional general anesthesia with a regimen of intravenous fentanyl 1-2 mcg/kg BW, propofol 2-3 ml/kg BW, and muscle relaxants for intubation, such as atracurium 0.5 mg/kg BW or rocuronium 0.6 mg/ kg BW. After that the patient will be intubated. The patient will be given local anesthesia Bupivacaine 0.25% in increments to the desired volume according to the desired height of the segmental block. Local anesthetic medication will be given intermittently every 2 hours
