Official Title: Effects of Intravenous Ephedrine in Preventing Intraoperative Hypothermia in Patients Undergoing Spinal Anesthesia for Arthroscopic Knee Surgery

Brief Summary: A prospective double-blinded randomized controlled study to determine efficacy of ephedrine in preserving core temperature in patients under neuraxial spinal anesthesia for knee arthroscopic surgery.

Detailed Summary: To determine the effect of ephedrine on preserving core temperature (tympanic) when given at finishing of local anesthetic administration for spinal neuraxial anesthesia comparing to normal saline (120 minutes period)
Sponsor: Ramathibodi Hospital

Current Primary Outcome: Tympanic temperature [ Time Frame: 120 minutes ]

Pre-operative, before and after performing spinal anesthesia, every 10 minutes after performing spinal anesthesia in 120 minutes duration


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Blood pressure [ Time Frame: 120 minutes ]
    Pre-operative, before and after performing spinal anesthesia, every 10 minutes after performing spinal anesthesia in 120 minutes duration
  • Shivering [ Time Frame: 120 minutes ]
    After performing spinal anesthesia in 120 minutes duration


Original Secondary Outcome: Same as current
