Insights
Preoperative peritonsillar ketamine injection effectively reduced pain after tonsillectomy in children. This method provided significant postoperative pain relief without increasing complications.
Area of Science:
- Anesthesiology
- Pediatric Surgery
- Pain Management
Background:
- Tonsillectomy is a common procedure with significant postoperative pain.
- Effective pain management is crucial for pediatric patients undergoing tonsillectomy.
- Previous research on ketamine for postoperative analgesia after tonsillectomy yielded mixed results.
Purpose of the Study:
- To evaluate the efficacy of preoperative peritonsillar ketamine injection for postoperative pain relief in children.
- To compare pain scores and complication rates between ketamine and saline groups.
Main Methods:
- A randomized controlled trial (RCT) involving sixty children aged 3-12 years.
- Participants received either 1 mg/kg ketamine or normal saline via peritonsillar injection five minutes before tonsillectomy.
- Pain was assessed using the Oucher Scale and CHEOPS; sedation was evaluated with the Wilson Sedation Scale.
Main Results:
- The ketamine group showed a statistically significant reduction in postoperative pain scores compared to the control group.
- Pain levels were lower in the ketamine group at two hours post-surgery.
- No significant differences were observed in the incidence of nausea and vomiting between the groups.
Conclusions:
- Peritonsillar ketamine injection administered preoperatively effectively reduces pain following tonsillectomy in children.
- This intervention offers a safe method for managing post-tonsillectomy pain without adverse effects.
Introduction:
Tonsillectomy is one of the most common surgical operations and has such complications as pain, hemorrhage and laryngospasm. Pain management is of vital importance in order to reduce the suffering and restlessness in children having undergone tonsillectomy. Different studies differ in their findings as to the use of ketamine for postoperative analgesia. The aim of this study was to investigate the effect of peritonsillar injection of ketamine preoperatively on postoperative pain relief.
Materials And Methods:
This was a randomized controlled trial (RCT) on sixty 3-12-year-old children. Children were randomly assigned to the intervention and control groups. Peritonsillar injection consisted of 1 mg/kg ketamine in the intervention group and of normal saline in the control group. An injection of 1 cc was administered on each side five minutes prior to tonsillectomy. Pain assessment was performed using the self-report Oucher Scale and CHEOPS (Children's Hospital of Eastern Ontario Pain Scale) and sedative state assessment was performed using the Wilson Sedation Scale. Pain, medication and complications were studied for 24 hours. Data analysis was performed using chi-squared test and t-test.
Results:
The ketamine group had a lower pain score compared with the control group (1.40±1.003 compared with 1.53±1.074). The average pain was less in the control group two hours after the surgery. The difference was statistically significant. There was no difference between the two groups in terms of nausea and vomiting incidence.
Conclusion:
The peritonsillar injection of ketamine five minutes prior to the surgery reduces the post-tonsillectomy pain without causing any complications.

Local Anesthetics: Clinical Application as Epidural Anesthesia
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
