A Randomized Comparison Simulating Face to Face Endotracheal Intubation of Pentax Airway Scope, C-MAC Video Laryngoscope, Glidescope Video Laryngoscope, and Macintosh Laryngoscope.

OBJECTIVES: Early airway management is very important for severely ill patients. This study aimed to investigate the efficacy of face to face intubation in four different types of laryngoscopes (Macintosh laryngoscope, Pentax airway scope (AWS), Glidescope video laryngoscope (GVL), and C-MAC video laryngoscope (C-MAC)). METHOD: Ninety-five nurses and emergency medical technicians were trained to use the AWS, C-MAC, GVL and Macintosh laryngoscope with standard airway trainer manikin and face to face intubation. We compared VCET (vocal cord exposure time), tube pass time, 1st ventilation time, VCET to tube pass time, tube pass time to 1st ventilation time, and POGO (percentage of glottis opening) score. In addition, we compared success rate according to the number of attempts and complications. RESULT: VCET was similar among all laryngoscopes and POGO score was higher in AWS. AWS and Macintosh blade were faster than GVL and C-MAC in total intubation time. Face to face intubation success rate was lower in GVL than other laryngoscopes. CONCLUSION: AWS and Macintosh were favorable laryngoscopes in face to face intubation. GVL had disadvantage performing face to face intubation.

The timing of surgery and mortality in elderly hip fractures: A retrospective, multicenteric cohort study.

BACKGROUND: Early surgery is recommended for elderly hip fracture patients, but some studies show no clear advantage. The benefits of early surgery may differ according to the medical environment in different countries. The purpose of this study was to identify the potential benefits of early surgery in elderly hip fracture patients by evaluating the effect of timing of surgery on mortality. MATERIALS AND METHODS: A retrospective study was conducted at multiple centers on hip fracture patients aged over 65 years. The primary outcome was 1 year mortality and the secondary outcomes were 30-day/6-month mortality and complications during admission. The effect of time to surgery on mortality was analyzed using a Cox proportional-hazards model. RESULTS: Among the 874 patients, 162 (18.5%) received surgery within 3 days and their 1-year mortality rate was 9.9%. However, the 1-year mortality rate for the delayed surgery group was 12.5%. After adjustment for potential confounders, the 1-year mortality rates in patients who received surgery in 3-7 days (Hazard ratio = 1.0; 95% confidence interval [CI]: 0.7-1.6) and over 7 days (hazard ratio = 1.3; 95% CI: 0.9-1.8) were not significantly different. In addition, the time to surgery did not have a significant effect on 30-day mortality, 60-day mortality or complications arising during hospitalization. CONCLUSIONS: The time to surgery did not affect short and long term mortality or the in hospital complication rate in elderly hip fracture patients. We recommend concentrating more on optimizing the condition of patients early with sufficient medical treatment rather than being bound by absolute timing of surgery.

Factors associated with successful second and third intubation attempts in the ED.

PURPOSE: The aim of this study was to identify the factors associated with successful second and third attempts in adults following a failed first intubation attempt in the emergency department (ED). METHODS: This was a retrospective analysis of the data from a multicenter, prospective, observational airway registry in South Korea. We obtained demographic and clinical data of intubated adult patients in 6 academic EDs from January 2007 to December 2010. The primary outcome was successful rescue attempt, which was defined as the successful placement of an endotracheal tube following a failed first intubation attempt. Logistic regression analyses were conducted to develop a multivariate model identifying factors associated with successful second and third attempts. RESULTS: Of 5905 adult patients, 1122 (19.0%) failed a first intubation attempt. The success rates of the second and third attempts were 79.2% and 78.5%, respectively. In the multivariate logistic regression analysis, factors associated with a successful second attempt were emergency physicians, senior physicians, nondifficult airway, and the use of a rapid sequence intubation (RSI) (odds ratio = 2.81 [95% confidence interval, 1.80-4.37], 1.50 [1.10-2.07], 2.15 [1.53-3.01], and 1.53 [1.01-2.33], respectively). Nondifficult airway and the use of RSI were associated with successful third attempts (5.48 [2.69-11.18] and 2.63 [1.08-6.40], respectively). CONCLUSIONS: Nondifficult airway and the use of RSI were associated with successful second and third intubation attempts. The use of RSI, backup by experienced senior physicians, and preparation for management of a difficult airway could be strategies for successful rescue intubation attempts in the ED.

The factors associated with successful paediatric endotracheal intubation on the first attempt in emergency departments: a 13-emergency-department registry study.

BACKGROUND: We investigated which factors are associated with successful paediatric endotracheal intubation (ETI) on the first attempt in emergency department (EDs) from multicentre emergency airway registry data. METHODS: We created a multicentre registry of intubations at 13 EDs and performed surveillance over 5 years. Each intubator filled out a data form after an intubation. We defined "paediatric patients" as patients younger than 10 years of age. We assessed the specialty and level of training of intubator, the method, the equipment, and the associated adverse events. We analysed the intubation success rates on the first attempt (first-pass success, FPS) based on these variables. RESULTS: A total of 430 ETIs were performed on 281 children seen in the ED. The overall FPS rate was 67.6%, but emergency medicine (EM) physicians showed a significantly greater success rate of 74.4%. In the logistic regression analysis, the intubator's specialty was the only independent predictive factor for paediatric FPS. In the subgroup analysis, the EM physicians used the rapid sequence intubation/intubation (RSI) method and Macintosh laryngoscope more frequently than physicians of other specialties. ETI-related adverse events occurred in 21 (7.2%) out of the 281 cases. The most common adverse event in the FPS group was mainstem bronchus intubation, and vomiting was the most common event in the non-FPS group. The incidence of adverse events was lower in the FPS group than in the non-FPS group, but this difference was not statistically significant. CONCLUSIONS: The intubator's specialty was the major factor associated with FPS in emergency department paediatric ETI, The overall ETI FPS rate among paediatric patients was 67.6%, but the EM physicians had a FPS rate of 74.4%. A well structured airway skill training program, and more actively using the RSI method are important and this could explain this differences.
