Intubation with channeled versus non-channeled video laryngoscopes in simulated difficult airway by junior doctors in an out-of-hospital setting: A crossover manikin study.

Failure to secure the airway is an important cause of morbidity and mortality during resuscitations. We compared the rate of successful intubation of the King Vision™ aBlade™ channeled and non-channeled video laryngoscopes, and McGRATH™ MAC video laryngoscope when used by junior doctors to intubate a simulated difficult airway in an out-of-hospital setting. 105 junior doctors were recruited in a crossover study to perform tracheal intubation with the three video laryngoscopes on a simulated difficult airway using the SimMan® 3G manikin. Primary outcome was the rate of successful intubations. Secondary outcomes were time-to-visualization, time-to-intubation and ease of use. Rates of successful intubations were higher for King Vision channeled and McGrath compared to the King Vision non-channeled (85.7% and 82.9% respectively versus 24.8%; p<0.001). Amongst the participants who had successful intubations, King Vision channeled and McGrath had shorter mean time-to-intubation compared to the King Vision non-channeled (41.3±20.3s and 38.5±18.7s respectively versus 53.8±23.8s, p<0.004;). There was no significant difference in the rate of successful intubation and mean time-to-intubation between King Vision channeled and McGrath. The King Vision channeled and McGrath video laryngoscopes demonstrated superior intubation success rates compared to King Vision non-channeled laryngoscope when used by junior doctors for intubating simulated difficult airway in an out-of-hospital setting. We postulated that the presence of a guidance channel in the King Vision channeled laryngoscope and the familiarity of the blade curvature and handling of the McGrath could have accounted for their improved intubation success rates.

Humanitarian Assistance and Disaster Relief mission by a tripartite medical team led by the Singapore Armed Forces after the 2015 Nepal earthquake.

INTRODUCTION: This study aimed to report the injury or disease patterns, challenges, key observations, and recommendations by the Singapore Armed Forces (SAF) team that embarked on an Humanitarian Assistance and Disaster Relief (HADR) mission in the aftermath of the April 2015 Nepal earthquake. METHODS: The SAF medical team that provided HADR assistance to Nepal consisted of personnel from the SAF, Singapore¢s Ministry of Health and the Royal Brunei Armed Forces. Upon arrival in Kathmandu, Nepal, the SAF medical team was assigned to the Gokarna district by the local health authorities. In addition to providing primary healthcare, the medical facility was equipped to perform resuscitation and minor procedures. We also assembled mobile medical teams (MMTs) that travelled to various remote areas of the country to deliver medical aid. RESULTS: A total of 3,014 patients were managed by the SAF medical team. Of these patients, 1,286 (42.7%) were men. 574 (19.0%) patients sustained earthquake-related injuries or illnesses, while 2,440 (81.0%) sustained non-earthquake-related injuries or illnesses. The team treated a total of 447 (77.9%) adults and 127 (22.1%) paediatric patients with earthquake-related injuries or illnesses. A significant number of patients developed exacerbations of underlying medical conditions. 2,161 (71.7%) patients were treated in our main facility in Gokarna, while 853 patients (28.3%) were treated by our MMTs. CONCLUSION: The ability to transport healthcare personnel and essential medical equipment within a short time allowed the SAF medical team to provide crucial medical care in the aftermath of the 2015 Nepal earthquake.
