Study type | Interventional |
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.

Primary | 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 | |
Primary | 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 | Numeric rating scale for pain assessment | Numeric rating scale score (NRS) is commonly used for measuring pain intensity. It is scored from 0-10; 0 means no pain and 10 is the worst pain imaginable. NRS assessed at the 120 minutes postoperatively | 120 minutes after surgery | |
Secondary | Systolic blood pressure | Measuring systolic blood pressure (mmHg) before surgery and 120 minutes after surgery and comparing values between and within group K and group C | immediately before surgery and 120 minutes after surgery | |
Secondary | diastolic blood pressure | Measuring diastolic blood pressure (mmHg) before surgery and 120 minutes after surgery and comparing values within groups and comparing values between and within group K and group C | immediately before surgery and 120 minutes after surgery | |
Secondary | heart rate | Measuring number of heart beats per minute before surgery and 120 minutes after surgery and comparing values within groups and comparing values between and within group K and group C | immediately before surgery and 120 minutes after surgery | |
Secondary | The Michigan Sedation Score assessment | Comparing depth of sedations of two groups using the University of Michigan Sedation Scale (UMSS). This sedation scale ranges from zero to four with higher numbers indicating deeper sedation. | immediately Before surgery, 60 minutes after surgery and 120 minutes after surgery | |
Secondary | Diplopia | Presence of absence of diplopia reported in clinical records electronic database by nurse or physician within time frame | 120 minutes after surgery | |
Secondary | Headache | Presence of absence of headache reported in clinical records electronic database by nurse or physician within time frame | 120 minutes after surgery | |
Secondary | Psychedelic phenomena | Presence of absence of psychedelic phenomena reported in clinical records electronic database by nurse or physician within time frame | 120 minutes after surgery | |
Secondary | Nausea | Presence of absence of nausea reported in clinical records electronic database by nurse or physician within time frame | 120 minutes after surgery | |
Secondary | Vomiting | Presence of absence of vomiting reported in clinical records electronic database by nurse or physician within time frame | 120 minutes after surgery | |
Secondary | Patient satisfaction | Evaluation of patient satisfaction 120 minutes after surgery. Satisfaction is rated on a scale of 1 to 4 (1 perfect, 2 good, 3 moderate, and 4 bad). | 120 minutes after surgery | |
Secondary | Physician satisfaction | Evaluation of physician satisfaction 120 minutes after surgery. Satisfaction is rated on a scale of 1 to 4 (1 perfect, 2 good, 3 moderate, and 4 bad). | 120 minutes after surgery |
