ABSTRACT
OBJECTIVE:
To observe the preoperative sedation, the status of separation from parents, compliance with the mask, hemodynamic parameters and postoperative agitation of intranasal dexmedetomidine (DEX) premedication on children undergoing dental rehabilitation under general anesthesia.METHODS:
In the study, 60 children of American Society of Anesthesiology classification (ASA I-II), aged 2-9 years, were randomly assigned to one of two equal groups. Thirty minutes before operation, control group received intranasal placebo (0.9% saline) 0.02 mL/kg, and DEX group received intranasal DEX 2 µg/kg. The preoperative sedation score, the status of separation from parents, compliance with the mask and hemodynamic parameters were recorded by an anesthesiologists until anesthesia induction. Recovery conditions, postoperative agitation were also recorded.RESULTS:
There was no significant difference between the two groups in patient characteristics, operation time, extubation time and recovery time. Compared with the children in control group, those in DEX group were significantly more sedated when they were separated from their parents (56.7% vs. 26.7%, P<0.05). Satisfactory compliance with mask application was 40% in control group vs. 73.3% in DEX group (P<0.05). There was no significant difference between the two groups regarding the incidences of postoperative agitation and oxygen saturation (SpO2). Compared with control group, the heart rate (HR) of DEX group was decreased after 20 minutes of drug administration [(97.13±12.93) beats/min vs.(104.53±11.97) beats/min, P<0.05]. The changes of the HR and SpO2 in the two groups were within the normal range. There were no incidences of bradycardia and hypoxemia in either of the groups during study observation.CONCLUSION:
Premedication with intranasal DEX 2 µg/kg for children undergoing dental rehabilitation under general anesthesia produces good preoperative sedation. The levels of sedation, scores of parental separation and compliance with the mask were satisfied. The children have good recovery conditions, and no obvious postoperative agitation and respiratory depression after DEX administration. Intranasal DEX 2 µg/kg is an effective and safe alternative for premedication in children.
