Objective: To investigate the neck features for laryngeal mask airway (LMA) size selection. Methods: This cross-sectional study was conducted on 160 patients referred for elective surgeries to Feiz Hospital affiliated with Isfahan University of Medical Sciences, Isfahan, Iran (April 2016 to September 2018). Patients underwent ventilation using LMA whose size was determined through a weighted-based approach. All of the patients’ neck characteristics including circumference, thyromental distance, and opening mouth were measured. Ventilation factors were recorded including numbers of attempts for successful LMA insertion, quality of ventilation, and sealing. Results: Neck circumference and thyromental distance were significantly different with the size of LMA (p 0.05 for all comparisons). However, the thyromental distance was significantly different with the quality ventilation status (p <0.0001). The total assessment of insertion attempts, ventilation efficacy and sealing was significantly different with the neck circumference (p <0.001), but thyromental distance did not show a significant difference (p>0.05). Conclusion: Findings demonstrated that neck circumference might be considered as an appropriate indicator for the selection of LMA size but neither the thyromental distance nor mouth opening. Further studies with a larger sample size are strongly recommended.

Objectives: To compare the results of early versus late tracheostomy in trauma patients admitted to intensive care unit (ICU).Methods: This was case control study being performed at a major trauma centre in Shiraz, Iran including 120 trauma patients admitted to ICU during a 2-year period and underwent tracheostomy during their ICU stay. The patients were categorized into two groups of the early tracheostomy who underwent tracheostomy within the first 7 days of initiation of mechanical ventilation (n=60), and the late tracheostomy group, in which tracheostomy was performed after 7 days (n=60). The duration of mechanical ventilation, ICU stay and hospital stay as well as mortality rates in ICU and hospital were recorded and compared between two study groups.Results: The baseline characteristics such as age (p=0.325), sex (p=0.071), Glasgow coma scale (GCS) (p=0.431) and the mechanism of injury (p=0.822) were comparable between two study groups. Early tracheostomy was associated with a significantly shorter duration of mechanical ventilation (p=0.008) and shorter ICU stay (p=0.003). Hospital stay (p=0.165), ICU mortality (p=0.243), and hospital mortality (p=0.311) were not different between the two study groups.Conclusion: Early tracheostomy is associated with reduced ICU stay and shorter duration of mechanical ventilation. Adopting a standardized strategy may improve resource utilization.
