Abstract

Background and purpose of the study: Tracheal intubation without using muscle relaxants is one of the new techniques of anesthesia. In this study, the quality of tracheal intubation was evaluated in two techniques of anesthesia with propofol / remifentanil and sevoflurane / remifentanil through removing muscle relaxant. Methodology: In this single-blinded randomized clinical trial, 67 healthy children were investigated in two groups of propofol and sevoflurane. In propofol group, Lidocaine1.5 mg / kg, remifentanil 2 µg/kg and propofol 2 mg / kg were administered. In the sevoflurane group, lidocaine and remifentanil with the same dose and sevoflurane 6% were administered. The general quality of tracheal intubation was graded and recorded under the three titles of good, moderate, and poor, according to the criteria of ease of ventilation with mask, mandible mobility, vocal cords status, and the patient's body response during tracheal intubation. Results: General quality of tracheal intubation was good in 90.9% of patients who received propofol and in 94.1% of patients who received sevoflurane. Moreover, no significant difference was found between the two groups (P = 0.62). Conclusion: According to the research results, the combination of sevoflurane and remifentanil may have similar and even better effects than the combination of propofol and remifentanil in tracheal intubation in children undergoing dental work under the general anesthesia without muscle relaxant.
