Comparing Magnet and Magill forceps in success of nasal intubation of children

Abstract

The purpose of this study was to compare nasal intubation using Magnet at tip of the guide and external Magnet for directing the guide without Magill forceps with nasal intubation using Magill forceps. Methods and Materials: The present study was a randomized clinical trial of 3 - 10 year old children with ASA I, II adenotonsilectomy candidate in Tabriz Children Hospital. Patients were randomly divided into two groups, both groups were similarly anesthetized and then placed in both endotracheal tubes in the nasopharynx. After laryngoscopy, in the first group, a magill forceps was used to guide the endotracheal tube and in the second group, a magnet was used to guide the endotracheal tube. Intubation time, the number of attempts and vital signs before induction, after induction and after intubation was measured and recorded in a questionnaire. Results: 83 patients were studied. Magill forceps was used in 42 cases and Magnet in 41 cases. Patients were generally 7.44 (± 2.14) years old. The mean weight was 25.38 (± 8.3). 51 patients (61.4%) were male and 32 patients (38.6%) were female. Two groups were not significantly different in age (p = 0.446), sex (p = 0.323) and weight (p = 0.098), endotracheal tube size (p= 1.000) and the vital signs before and after surgery. Intubation time was significantly shorter in Magent group than Magill group (P = 0.003). However, the frequency of attempts for successful intubation was once in most cases in both groups (95.2% in the Magill group and 92.7% in the Magnet group) and there was no significant difference between the two groups (P = 0.979).
