RESUMEN

BACKGROUND: The i-gel™ (i-gel) and Laryngeal Mask Airway Supreme™ (LMA Supreme) have been safely used in children. We compared the airway performance of the i-gel and LMA Supreme in infants undergoing general anesthesia. METHODS: Sixty infants with American Society of Anesthesiologists physical status I or II were randomly assigned to place either the i-gel or the LMA Supreme. The size 1 or 1.5 of each airway was selected by the weight of infants. The primary outcome variable was oropharyngeal leak pressure (OLP). We also assessed insertion success rate, insertion time, fiberoptic view of the larynx, airway quality, airway manipulations, and perioperative complications. RESULTS: Demographic data did not differ between the two groups. Insertion success rate was similar in both groups. OLP for the i-gel (26.0 ± 3.8 cmH2O) was higher than for the LMA Supreme (23.7 ± 3.2 cmH2O) (P = 0.016). Insertion time for the i-gel (16.4 ± 2.8 s) was shorter than for the LMA Supreme (18.5 ± 2.7 s) (P = 0.002). There were no differences in fiberoptic view of the larynx, airway quality, airway manipulations, and complications between the two groups. CONCLUSIONS: This study demonstrated that the i-gel and LMA Supreme provided a similar performance of airway in infants. Compared with the LMA Supreme, the i-gel provided shorter insertion time and higher OLP in infants.

RESUMEN

BACKGROUND: Malpositioning of the endotracheal tube within airway after intubation may results in serious complications, such as accidental extubation and inadvertent endobronchial intubation. Therefore, early detection of malposioning of the endotracheal tube is very impotant for deciding patient's prognosis. METHODS: We assessed the distance from the tip of the endotracheal tube to the carina according to the patient's age, sex, and the time, the location, and the route of intubation. The chest x-ray was taken for 333 patients (men, 226: women, 107) who were admitted to the intensive care unit of Wonju Christian Hospital from march 1, 1995 to February 28, 1996. Chest x-ray was obtained after intubation to verify endotracheal tube position. Appropriate endotracheal tube position on chest x-ray was defined as between 2 and 6 cm above the carina. RESULTS: Of the 333 intubations, 106 (31.8%) endotracheal tubes were inappropriately placed according to the chest x-ray. The percentage of malpositioned endotracheal tubes (<2 cm) was higher in women than in men (11.2% vs. 5.3%, p<0.05), with higher in night (7 PM to 7 AM) than in day (7 AM to 7 PM) (42% vs. 24%, p<0.05). Distance from the carina to the tip of endotracheal tube is 4.34 +/- 1.77cm in women and 5.23 +/- 1.64cm in men. Thus, position of the endotracheal tube in women is deeper than men (p<0.001). CONCLUSIONS: We conclude that the chest x-ray for confirmation of endotracheal tube position after endotracheal intubation may remain the standard of practice. And endotracheal tube position should be carefully assessed immediately after tracheal intubation, particularly in women and at night.
