Role of Pericapsular Nerve Block Using Dexmedetomidine and Bupivacaine in Improving the Outcome of Patients Undergoing Hip Surgery Under Spinal Anesthesia

The PENG block will be performed using a mixture of 0.25% bupivacaine (1.25 to 2.5 mg/kg.) combined with dexmedetomidine at a dose of 1.25 mcg/kg

a typical dose of 0.5% hyperbaric bupivacaine ranges from 0.1 to 0.15 mg/kg (2 to 3 mL), depending on the patient's height and clinical condition. Lower doses are used for shorter or elderly patients, while taller patients may require higher doses
