Insights
Clonidine reduced postoperative agitation in children undergoing strabismus surgery, leading to higher parent satisfaction. While patients stayed slightly longer in recovery, the benefits of decreased agitation were notable.
Area of Science:
- Pediatric Anesthesiology
- Pharmacology
- Surgical Recovery
Background:
- Postoperative agitation is a frequent complication in children after anesthesia, particularly with inhalation agents.
- This agitation negatively impacts patient recovery and parental well-being.
- Strabismus surgery in children is a common procedure where this issue arises.
Purpose of the Study:
- To investigate the efficacy of clonidine, an alpha-2 agonist, in reducing postoperative agitation in children.
- To assess the impact of clonidine on parent satisfaction following strabismus surgery.
- To evaluate clonidine's effect on recovery metrics in pediatric patients.
Main Methods:
- A prospective, double-blind, randomized controlled trial involving 50 children undergoing strabismus surgery.
- Children received either clonidine or a placebo prior to surgery.
- Postoperative agitation was assessed using the Pediatric Anesthesia Emergence Delirium and Watcha scales, alongside parent questionnaires.
Main Results:
- Clonidine administration showed a statistically significant improvement in postoperative agitation at 15 minutes and the last recorded score on the Watcha scale (P = .096 and P = .095, respectively).
- The clonidine group experienced a slightly longer, though not statistically significant, stay in the post-anesthesia care unit (54 min vs. 47 min, P = .17).
- Parent satisfaction was higher in the clonidine group (71% "very satisfied") compared to placebo (46%), although this difference did not reach statistical significance (P = .34).
Conclusions:
- Clonidine demonstrates a small but observable reduction in postoperative agitation for children undergoing strabismus surgery.
- While post-anesthesia care unit stay may slightly increase, clonidine is associated with enhanced parental satisfaction.
- The findings suggest clonidine as a potential agent for managing pediatric postoperative agitation and improving the recovery experience.
Purpose:
Postoperative agitation is common in adults and children following the use of several anesthetics, particularly inhalation anesthetics. This behavior has detrimental effects both physically for the patient following the procedure and psychologically for the parent or guardian. The authors propose that clonidine, an alpha-2 agonist, would provide a reduction in children's postoperative agitation and, in turn, improve parent satisfaction in children undergoing strabismus surgery.
Methods:
Fifty children were prospectively randomized to receive either clonidine or placebo in a double-blind fashion prior to surgery. The children were evaluated using preoperative and postoperative parent questionnaires and postoperative behavioral evaluation using standardized scales including the Pediatric Anesthesia Emergence Delirium and Watcha scales.
Results:
Children receiving clonidine immediately after anesthesia induction had statistically significant improvement in postoperative agitation at the 15-minute mark (P = .096) and last score obtained (P = .095) using the Watcha scale. The clonidine group spent an insignificantly longer time in the post-anesthesia care unit (average: 54 minutes) than the placebo group (average 47 minutes) (P = .17). Seventy-one percent of parents reported being "very satisfied" with their child's recovery from anesthesia in the clonidine group compared to 46% in the placebo group, although this was not statistically significant (P = .34).
Conclusions:
Children receiving clonidine prior to undergoing strabismus surgery have a small but noticeable reduction in postoperative agitation, stay slightly longer in the post-anesthesia care unit, and have higher rates of parent satisfaction.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
