Role Of Pre Emptive Ketamine In Post Operative Pain Control For Patients Undergoing Modified Radical Mastectomy

This study is a prospective observational study to determine the role of pre emptive intravenous ketamine in post operative pain control of patients undergoing modified radical mastectomy.The primary objective of the study is to assess the severity of post operative pain using Visual Analogue Scale score among post modified radical mastectomy patients who received and not received pre emptive ketamine.And the secondary objective of the study is to asses the Interval time for first rescue analgesic,Total number and dose of analgesic injections in first 24 hours,Occurence of adverse effects like hallucination,delirium and visual disturbances within first 24 hours.This study helps in determining the role of intravenous ketamine as pre emptive analgesic and its post operative analgesic sparing effect on patients undergoing modified radical mastectomy.Low dose ketamine (less than 1mg/kg) helps in attaining adequate post operative pain with minimal adverse effects and haemodynamic changes.Adequate post operative analgesia with opioid sparing and minimal adverse effects can help in increasing patient satisfaction.
