Insights
Low-dose esketamine significantly reduced emergency agitation in children after tonsillectomy. This intervention did not prolong extubation or increase side effects, offering a safe option for pediatric anesthesia.
Area of Science:
- Anesthesiology
- Pediatric Surgery
- Pharmacology
Background:
- Emergency agitation is a frequent postoperative complication in children undergoing general anesthesia.
- Tonsillectomy is a common pediatric surgical procedure where this complication is observed.
Purpose of the Study:
- To investigate the efficacy of a low dose of esketamine in mitigating emergency agitation in pediatric patients post-tonsillectomy.
- To evaluate the safety profile of low-dose esketamine in this patient population.
Main Methods:
- A prospective study involving 80 children undergoing tonsillectomy, randomized into esketamine and control groups.
- Standardized anesthesia protocols were used; the esketamine group received 0.25 μg/kg esketamine post-surgery.
- Key metrics included extubation time, eye-opening time, Ramsay sedation scale, PACU discharge time, and postoperative complications.
Main Results:
- The incidence of emergency agitation was significantly lower in the esketamine group (5%) compared to the control group (27.5%).
- Eye-opening time was slightly prolonged in the esketamine group (17.2 min vs. 15.5 min).
- Extubation time and PACU discharge time remained comparable between groups, with no increase in other adverse events.
Conclusions:
- Low-dose esketamine effectively reduces emergency agitation in children after tonsillectomy.
- This intervention is safe and does not negatively impact recovery times or increase other postoperative complications.
Abstract:
Background: Emergency agitation is a common postoperative complication in pediatric patients after general anesthesia. The aim of this study was to explore the effects of a low dose of esketamine on emergency agitation in children following tonsillectomy. Materials and Methods: Eighty children were recruited prospectively to this study and divided into the esketamine group and the control group (40 cases in each group). The induction and maintenance of anesthesia were the same in both groups. At the end of surgery, the esketamine group received 0.25 μg/kg esketamine, while the control group received the same volume of normal saline. The extubation time, time to eye opening, Ramsay sedation scale and time to discharge from the post-anesthesia care unit (PACU) were recorded during post-anesthesia care unit. Postoperative complications, such as emergency agitation, respiratory depression, hypertension, tachycardia, nightmares, nausea, and vomiting, were also recorded. Results: The incidence of emergency agitation was lower in the esketamine group compared with that in the control group (5% vs. 27.5%, p = 0.006). The time to eye opening was longer in the esketamine group than in the control group (17.2 ± 2.7 vs. 15.5 ± 2.3 min, p = 0.005). However, the extubation time and time to discharge from PACU were similar between the two groups. Conclusion: Low-dose of esketamine decreases the incidence of emergency agitation in children after tonsillectomy without delaying extubation time and increasing the postoperative side effects.
