Insights
Clonidine effectively prevents postoperative agitation in children after sevoflurane anesthesia. This study found significantly less agitation in children receiving clonidine compared to placebo.
Area of Science:
- Anesthesiology
- Pediatric Surgery
Background:
- Postoperative agitation is a common complication in pediatric patients recovering from sevoflurane anesthesia.
- Effective management strategies are needed to improve patient recovery and reduce distress.
Purpose of the Study:
- To evaluate the efficacy of clonidine in preventing postoperative agitation in male children undergoing circumcision.
- To assess the impact of clonidine on agitation incidence and severity following sevoflurane anesthesia.
Main Methods:
- A double-blinded, randomized trial involving 40 male children aged 2-7 years undergoing circumcision.
- Patients received either intravenous clonidine (2 microg/kg) or placebo after anesthetic induction with sevoflurane.
- Agitation was assessed for 2 hours post-surgery, with severe agitation treated by midazolam.
Main Results:
- Significantly lower incidence of agitation was observed in the clonidine group (2 patients) compared to the placebo group (16 patients) (P < 0.001).
- No patients in the clonidine group experienced severe agitation, versus 6 in the placebo group (P = 0.02).
- Clonidine-treated patients showed significantly decreased heart rate and blood pressure postoperatively (P < 0.05).
Conclusions:
- Clonidine at 2 microg/kg IV effectively reduces the incidence and severity of agitation after sevoflurane anesthesia in pediatric patients.
- The benefits of clonidine in preventing agitation were observed without clinically significant bradycardia or hypotension.
Unlabelled:
In a double-blinded trial, 40 male children (age 2-7 yr) undergoing circumcision were randomly assigned to receive clonidine 2 microg/kg IV or placebo after anesthetic induction. For induction and maintenance of anesthesia, we used sevoflurane as the sole anesthetic. For pain treatment, a penile block was performed before surgery. After surgery the incidence and severity of agitation was measured during an observation period of 2 h. Severe agitation was treated with midazolam. In 16 placebo and 2 clonidine-treated patients agitation was observed (P < 0.001). In 6 patients of the Placebo group, agitation was graded as severe, whereas none of the patients in the Clonidine group developed severe agitation (P = 0.02). During the postoperative period heart rate and blood pressure were significantly decreased in clonidine treated patients (P < 0.05). We conclude that clonidine effectively prevents agitation after sevoflurane anesthesia.
Implications:
The recovery from sevoflurane anesthesia may be complicated by the presence of agitation in pediatric patients. Clonidine 2 microg/kg IV after anesthetic induction effectively reduces the incidence of agitation without resulting in clinically relevant bradycardia and hypotension.

Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...
