Summary

In our study, it was aimed to show the contribution of intraoperative intravenous magnesium sulfate administration to peroperative opioid consumption and postoperative analgesia.

Conditions

  • Laparoscopic Hysterectomy
  • Magnesium Sulfate
  • General Anesthesia

Interventions

DRUG

magnesium sulfate group

Anesthesia induction was provided with propofol (2mg/kg), fentanyl (2mcg/kg). Intubation was performed after administration of 0.6 mg/kg rocuronium with an appropriate endotracheal tube. Anesthesia was maintained using AIR/O2 (50%/50%), 1 minimum alveolar concentration (MAC) sevoflurane, 0.1-0.25 mcg/kg/min remifentanil infusion. The target BIS value was kept between 40 and 50. Systolic blood pressure (SBP) \<90mmHg or \<20% of baseline was considered hypotension; remifentanil infusion was reduced. If no response was obtained, 5-10 mg of IV ephedrine was administered. HR \< 45 beats/min was evaluated as bradycardia; IV atropine 0.5 mg was planned The magnesium group received a bolus of 20 mg/kg of magnesium sulfate in 100 mL of saline for 15 minutes prior to induction, followed by a continuous infusion of 20 mg/kg/hr until skin closure.
