Insights
Ketamine effectively reduces the need for postoperative pain medication and provides pain relief when administered before tonsillectomy surgery. This study highlights ketamine
Area of Science:
- Anesthesiology and Pain Management
- Pediatric Surgery
Background:
- Postoperative pain management after tonsillectomy in children is crucial.
- Exploring novel analgesic strategies is essential for improving patient outcomes.
Purpose of the Study:
- To assess the efficacy of ketamine in preventing postoperative pain following tonsillectomy.
- To evaluate the impact of perioperative ketamine administration on analgesic requirements.
Main Methods:
- A randomized, prospective, double-blind study was conducted with 90 pediatric patients (ASA I-II).
- Patients received either pre-incisional intravenous ketamine infusion, intraoperative ketamine, or saline placebo.
- Pain scores and tramadol consumption were recorded post-surgery.
Main Results:
- The group receiving ketamine pre-surgery (pain preventive group) showed significantly lower verbal pain scale scores at 4 and 6 hours postoperatively.
- Total tramadol requirement was substantially reduced in the pain preventive group compared to other groups.
- No significant differences were observed in recovery from anesthesia or discharge parameters among the groups.
Conclusions:
- Perioperative ketamine administration, particularly when given before surgery, effectively reduces postoperative analgesic needs in pediatric tonsillectomy patients.
- Ketamine demonstrates significant analgesic properties in the early postoperative period following tonsillectomy.
- Ketamine is a viable option for managing pain after tonsillectomy/adenotonsillectomy.
Study Objectives:
To evaluate the effectiveness of ketamine in the prevention of postoperative pain after tonsillectomy.
Design:
Randomized, prospective, double-blind study.
Setting:
University hospital.
Patients:
90 ASA physical status I and II patients, aged 5 to 15 years, scheduled for tonsillectomy or adenotonsillectomy.
Interventions:
Patients were divided into three groups. The pain preventive group received intravenous (IV) ketamine 0.5 mg/kg in 2 mL saline before the tonsils were surgically removed, followed by a continuous IV infusion of ketamine at 6 micro/(kg/min). In the ketamine group, 2 mL saline was given before the tonsils were surgically removed; saline infusion (10 mL/h) was continued until bleeding control, and 0.8 mg/kg ketamine was given during bleeding control in 2 mL saline. In the control group, only saline was given.
Measurements And Main Results:
Cardiorespiratory system data, recovery from anesthesia and discharge parameters, tramadol requirement, and complications were recorded. Recovery from anesthesia and discharge parameters were similar among the groups. Total dose of tramadol was lower in the pain preventive group than in the other groups. In the pain preventive group, verbal pain scale scores were lower in the early postoperative period in the fourth and sixth hours (P < 0.05).
Conclusions:
Ketamine decreases postoperative analgesic requirements and has analgesic effects when used before surgery in tonsillectomy/adenotonsillectomy.
