Spine Surgery
Conditions
Brief summary
Anesthesia for neurosurgery requires balancing deep and effective anesthesia as well as postoperative analgesia versus the risks of delayed recovery and postoperative respiratory depression. This randomized placebo-controlled, double-blind study was designed to evaluate the effect of magnesium sulfate on the total anesthetic and analgesic consumption using the clinical parameters in addition to the effect on IONM reading.
Detailed description
Objectives: 1. Decrease anesthetic consumption 2. Decrease use of muscle relaxants 3. Decrease analgesic consumption 4. Excellent recovery Patients & Methods: * 2 groups (total 50) Randomized Controlled Double Blind (RCDB) Study * Propofol + remifentanil + saline (Control = C group) * Propofol + remifentanil + Mgso4 (Magnesium = M group) * Adult Spine decompression and fixation After getting the Institutional Review Board (IRB) approval, This randomized controlled double blind study includes 2 groups of patients (each group 25) will be enrolled in the study. All patients undergo spine decompression and fixation surgery Induction: All patients in the study will receive iv fentanyl 2 mic/kg + propofol 2mg/kg and endotracheal intubation will be facilitated with rocuronium 0.60 mg/ kg. Then anesthesia will be maintained using total intravenous anesthesia with propofol (6-9 mg/kg/hr) + remifentanil (0.03-0.05 mic / kg/ min) Group 1 (C group) : Receive 10 mg/kg /hr 0.9% Normal Saline Group 2 (M group) : Receive 10 mg/kg/hr Magnesium Sulfate Monitoring: 1. IONM 2. train-of-four (TOF) 3. bispectral index (BIS) Measurements: 1. IO Anesthetic Consumption 2. IO Hemodynamics 3. somatosensory evoked potential (SSEP), motor evoked potential (MEP), TOF, BIS Readings 4. PO visual analogue scale (VAS) (24hours) 5. PO Morphine Consumption (24hours)
