Background. Skiing is a high-risk winter sport, and the rate of injury fatality is the highest compared to other winter sports. During skiing rescue, the harsh natural environments will increase the difficulty of artificial airway establishment. There has been no research focusing on the establishment of the artificial airway during skiing rescue site. This study aims to simulate the real-world scenario, calculating and comparing the operation time of different artificial airways on the cold slope, and to explore the optimal method of establishing artificial airway on the cold slope, sharing our experience, technical notes, and pitfalls we encountered, hoping to help establish a standard operating procedure in advanced airway management on the ski slope. Methods. The simulated human was placed on the cold slope with the head under the feet. Artificial airway was established by the same anesthesiologist using endotracheal intubation (endotracheal intubation group), LMA Supreme laryngeal mask (LMA group), and I-gel laryngeal mask (I-gel group). Each method was repeated 5 times, and the operation time and whether it was successful by one attempt were recorded and compared between groups. Results. Three groups of artificial airway were successful by one attempt.. The bite block dropped and drifted away for one time in the endotracheal intubation group. Operation time is 209.2 ± 32.7 seconds in the endotracheal intubation group, 72.2 ± 3.1 seconds in the LMA group, and 52.6 ± 4.2 seconds in the I-gel group. ANOVA showed that there was a significant difference in the operation time among the three groups ( p < 0.001 ). Tukey’s post hoc test showed that there were statistically significant differences between the endotracheal intubation group and the other two groups in operation time, p < 0.001 , while there was no significant difference between the LMA group and I-gel group ( p = 0.275 ). Conclusion. The artificial airway can be completed by endotracheal intubation and LMA and I-gel laryngeal mask insertion on the cold slope. Artificial airway with the I-gel laryngeal mask takes the shortest time in this study. Extra caution should be paid to slippery and drifting.

Induction Of Anaesthesia

Inhalation induction with sevoflurane was compared with propofol or sevoflurane/propofol in 60 unpremedicated adults. Target concentrations for the three groups (with 60% nitrous oxide) were 3% end-tidal sevoflurane, 12 mg/l propofol and 1.5% sevoflurane/6 mg/l propofol respectively, prior to insertion of a laryngeal mask airway (LMA) at 10 minutes. Induction of anaesthesia was satisfactory in each group, but movement response to LMA insertion was observed in 20 patients (least in the sevoflurane group). Cardiovascular responses were similar except for a lower heart rate in the sevoflurane group. EEG bispectral index suggested a greater depth of anaesthesia in the inhalation induction group. A bispectral index of 60 separated patients responding to LMA insertion from nonresponders (P=0.006), and had a sensitivity of 68% and specificity 70%. Movement response was not predicted by cardiovascular changes.

Laryngeal Mask Insertion

The incidence of bacteraemia following insertion of the laryngeal mask airway (LMA) was investigated in one hundred fit patients. Four cultures were positive: three represented contamination with skin flora; the other was a microaerophilic streptococcus grown from an anaerobic culture bottle. Although this organism can be pathogenic, it may also represent contamination. Our findings suggest that significant bacteraemia on insertion of the LMA is uncommon and is probably no more than with oral intubation. Antibiotic prophylaxis is of doubtful benefit in these circumstances.

Objective To collect computed tomography data of the laryngeal anatomy of Chinese men and to determine the feasibility of using the size 4 Ambu AuraOnce laryngeal mask (Ambu A/S, Copenhagen, Denmark) in Chinese men weighing >70 kg. Methods This prospective study involved men who underwent surgery from May 2018 to January 2019 at Jinshan Hospital. Pharyngeal and laryngeal parameters were measured by computed tomography. The laryngeal mask insertion success rate, requirement for tracheal tube insertion, laryngeal mask insertion time, fiberoptic bronchoscopy grading, air leakage pressure, and pharyngeal complications were analyzed. Results In a comparison of the size 4 and 5 Ambu AuraOnce devices, the first insertion success rate was 100% and 87% and the three-times insertion success rate was 100% and 93%, respectively, with no significant differences. However, the insertion time was significantly different at 19.6 ± 5.9 versus 31.1 ± 11.2 s, respectively, and the proportions of fiberoptic grading levels were also significantly different. There were no significant differences in the air leakage pressure or pharyngeal complications. Conclusion The size 4 Ambu AuraOnce is more adequate than the size 5 for Chinese men weighing >70 kg, with a shorter insertion time and higher fiberoptic bronchoscopic grading.
