About

The investigators will test the effects of dexamethasone versus dexmedetomidine as adjuvant to bupivacaine in IPACK Block and it's direct effect in decreasing pain post operative following Arthroscopic knee surgeries

Full description

A.Preoperative settings: All patients will be assessed preoperatively by careful history taking, full physical examination, and laboratory evaluation. An informed written consent will be taken from every patient just before the surgery. B.Intraoperative and postoperative settings: On arrival to the operating room, baseline parameters such as ECG, mean arterial blood pressure, heart rate, and oxygen saturation will be recorded. Intravenous line will be inserted and IV Ringer's solution will be started, 500ml bolus will be given as a preload over 20 min before performing spinal anaesthesia and maintenance volume of 10ml\kg. For each group, patients will be put in supine position, the procedure will be performed under complete aseptic precautions and All patients will be divided into three groups:(Group 1) for iPACK block with 0.25% bupivacaine only. (Group 2) for iPACK block with 0.25% bupivacaine and dexamthasone and (Group 3) for iPACK block with 0.25% bupivacaine and dexmedetomidine .
