NCT05752110

Brief Summary

When given intravenously in doses below 1.2mg/kg, ketamine has been shown to work as an antidepressant. Ketamine is a common induction drug used during general anesthesia. It is known to reduce postoperative pain in this instance. Limited studies have evaluated the effect of a single subanesthetic dosage of ketamine administered as an adjunct to general anesthesia on acute mood states in patients undergoing minor surgery. The aim of this randomized controlled study was to examine if a single intravenous administration of 0.5 mg/kg ketamine given at the induction of propofol/fentanyl anesthesia has an effect on acute mood states before the discharge of women undergoing fractional curettage.

Outcome Measures

Primary Outcomes (2)

  • Comparing total mood scores of both groups using Profile of Mood States (POMS) Questionnaire.

    The Turkish version of Profile of Mood States (POMS) is an validated instrument that measures mood using a 58-item questionnaire with each item rated using a response scale of five categories ranging from "not at all" to "very strong". Higher score indicates worse mood.As a global measure of affective state, a total mood score (TMS) is calculated by combining the negative mood subscore (NMS) totals (fatigue-inertia, anger-hostility, confusion-bewilderment, depression-dejection, tension-anxiety,) and subtracting the positive mood subscore (PMS) (vigor-activity). The minimum value of TMS is -24, the maximum value is+177.

    Total Mood Score measured 120 minutes after surgery

  • Impact of clinical variables on total mood scores using Profile of Mood States (POMS)

    We perform multiple linear regression analyses to examine the independent predictors of changes in postoperative TMS in the entire study group, patients in group-K and group-C, separately. Postoperative TMS is the dependent variable; menopausal status, parity, educational level, body mass index (BMI) and preoperative TMS are independent variables.

    120 minutes after surgery

Secondary Outcomes (12)

  • Numeric rating scale for pain assessment

    120 minutes after surgery

  • Systolic blood pressure

    immediately before surgery and 120 minutes after surgery

  • diastolic blood pressure

    immediately before surgery and 120 minutes after surgery

  • heart rate

    immediately before surgery and 120 minutes after surgery

  • The Michigan Sedation Score assessment

    immediately Before surgery, 60 minutes after surgery and 120 minutes after surgery

  • +7 more secondary outcomes
