Context:The newest variation of the i-gel supraglottic airway is a pediatric version.Aims:This study was designed to investigate the usefulness of the size 2 i-gel compared with the classic laryngeal mask airway (cLMA) of the same size in anesthetized, paralyzed children.Settings and Design:A prospective, randomized, single-blinded study was conducted in tertiary care teaching hospital.Subject and Methods:Sixty ASA grade I–II patients undergoing lower abdominal, inguinal, and orthopedic surgery were included in this prospective study. The patients were randomly assigned to i-gel and cLMA groups (30 patients in each group). Size 2 supraglottic airway was inserted according to the assigned group. We assessed ease of insertion, hemodynamic data, oropharyngeal sealing pressure, and postoperative complications.Statistical Analysis Used:Parametric data were analyzed with the unpaired t-test and non-parametric data were analyzed with the Chi-square test. Unless otherwise stated, data are presented as mean (SD). Significance was taken as P < 0.05.Results:There were no differences in the demographic and hemodynamic data among the two groups. The airway leak pressure of the i-gel group (26.1 ± 2.4 cm H2O) was significantly higher than that of the cLMA group (22.64 ± 2.2 cm H2O). The success rates for first attempt of insertion were similar among the two devices. There were no differences in the incidence of postoperative airway morbidity among the two groups.Conclusions:Hemodynamic parameters, ease of insertion, and postoperative complications were comparable between the i-gel and cLMA groups, but airway sealing pressure was significantly higher in i-gel group.
Background and Aims:The Airtraq™ optical laryngoscope is the only marketed videolaryngoscope for paediatric patients besides the fibre-optic bronchoscope. We hypothesized that intubation would be easier with Airtraq™ compared to Miller blade. Hence, we compared Airtraq™ with the Miller laryngoscope as intubation devices in paediatric patients.Methods:This prospective, randomized study was conducted in a tertiary care teaching hospital. Sixty children belonging to American Society of Anesthesiologists' Grade I–II, aged 2–10 years, posted for routine surgery requiring tracheal intubation were randomly allocated to undergo intubation using a Miller (n = 30) or Airtraq™ (n = 30) laryngoscope. The primary outcome measure was time of intubation. We also measured ease of intubation, number of attempts, percentage of glottic opening score (POGO), haemodynamic changes and airway trauma. Student t test was used to analyse parametric data.Results:Intubation time was comparable between Miller's laryngoscope (15.13 ± 1.33s) compared to Airtraq™ (11.53 ± 0.49 s) (P = 0.29) The number of first and second attempts at intubation were 25 and 5 for the Miller laryngoscope and 29 and 1 for the Airtraq™. Median visual analogue score (VAS) for ease of intubation was 5 in Miller group compared to 3 in Airtraq™ group. The median POGO score was 75 in the Miller group and 100 in the Airtraq™ group (P = 0.01). Haemodynamic changes were maximum and most significant immediately and 1 min after intubation. Airway trauma occurred in three patients (9.09%) in Miller group and one patient (3.33%) in Airtraq™ group.Conclusion:The Airtraq™ reduced the difficulty of tracheal intubation and degree of haemodynamic stimulation compared to the Miller laryngoscope in paediatric patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
