Abstract
BACKGROUND AND OBJECTIVES: Endotracheal intubation is the most important and crucial step during administration of general anesthesia. It is more so in pediatric patients with associated deformities of cleft lip, palate, and alveolus. Propofol, an intravenous (i.v.) induction agent, has profound depressant effect on airway reflexes with a quick and smoother induction. Similarly, sevoflurane, an inhalational agent, has relatively pleasant smell, low airway irritability, and more cardiostable properties. Hence, we sought to compare effectiveness of propofol with sevoflurane in achieving good intubation conditions without the use of muscle relaxants. MATERIALS AND METHODS: In this prospective randomized study, eighty children belonging to American Society of Anesthesiologist physical status Class I and II, aged 1-10 years, scheduled for cleft surgery were included. All participants were premedicated. Patients were allotted to Group A and Group B randomly. Group A received propofol and Group B received sevoflurane as induction agents. Tracheal intubation was attempted in all patients at 150 s. Intubation conditions were assessed by using Steyn modification of Helbo-Hansen intubating conditions score. Statistical analysis was done using Student's t-test and Chi-square test with P < 0.05 regarded as significant. RESULTS: Group B patients receiving sevoflurane had significantly more clinically acceptable intubation conditions than patients of Group A receiving i.v. propofol (P = 0.001). CONCLUSION: We conclude that intubation conditions using inhalational 8% sevoflurane are superior to i.v. propofol of 3 mg/kg for tracheal intubation without muscle relaxants in children undergoing cleft surgeries.
