Application of target controlled infusion propofol sedation in dental fear children for dental extraction

Objective:To observer the sedative effects in 56 dental fear children who were treated by target controlled infusion propofol for teeth extractions.Methods:Sedation in 56 dental fear children was induced by target controlled infusion of propofol and the predicted drug concentration was 1.5 μg/ml.The HR,SpO2 and scores of sedation were measured and compared before and after TCI sedation.Results:Heart rates of the patients decreased slightly during operation,but there was no significant changes in heat rate and SpO2 before and after TCI sedation.Children were on the middle sedation states.Ramsay sedation score was 5.2±0.8,which was significantly different compared with that before TCI sedation.Conclusion:Target controlled infusion propofol sedation in dental fear children for dental extractions is effective,which has no obvious impact on respiration and circulation system.It is feasible in the management and treatment of dental fear during teeth extraction.
