Randomized Controlled Trial Multicenter StudyPredictors of Intubation in Patients With Acute Hypoxemic Respiratory Failure Treated With a Noninvasive Oxygenation Strategy.
In patients with acute hypoxemic respiratory failure, noninvasive ventilation and high-flow nasal cannula oxygen are alternative strategies to conventional oxygen therapy. Endotracheal intubation is frequently needed in these patients with a risk of delay, and early predictors of failure may help clinicians to decide early. We aimed to identify factors associated with intubation in patients with acute hypoxemic respiratory failure treated with different noninvasive oxygenation techniques. ⋯ In patients with acute hypoxemic respiratory failure breathing spontaneously, the respiratory rate was a predictor of intubation under standard oxygen, but not under high-flow nasal cannula oxygen or noninvasive ventilation. A PaO2/FIO2 below 200 mm Hg and a high tidal volume greater than 9 mL/kg were the two strong predictors of intubation under noninvasive ventilation.

Multicenter Study
An assessment of ventilation and perfusion markers in out-of-hospital cardiac arrest patients receiving mechanical CPR with endotracheal or supraglottic airways.
Mechanical chest compression (MCPR) devices are considered equivalent to manual compressions in patient outcomes in out-of-hospital cardiac arrest (OHCA). However, recent data suggest possible harm in patients with a supraglottic airway device (SGA) during MCPR. The aim of this study was to evaluate differences in direct and indirect markers of ventilation and perfusion in patients with cardiac arrest receiving MCPR and who had their airway managed with an endotracheal tube (ETT) or SGA. ⋯ In this retrospective study, we found no evidence of differences in markers of ventilation, perfusion or prehospital ROSC and survival in patients with OHCA who had their airway managed with either an ETT or SGA while receiving MCPR.

Obesity is deemed to increase the risk of difficult tracheal intubation. However, there is a dearth of research that examines the relationship of obesity with intubation success and adverse events in the emergency department (ED). We analyzed the data from a prospective, observational, multicenter study-the Japanese Emergency Airway Network (JEAN) 2 study from 2012 through 2016. ⋯ In the multivariable analysis, compared to the lean patients, overweight (adjusted odds ratio [OR], 0.85; 95%CI, 0.74-0.98) and obese (adjusted OR, 0.62; 95%CI, 0.49-0.79) patients had a significantly lower success rate on the first attempt. Additionally, obesity was significantly associated with a higher risk of adverse events (adjusted OR, 1.62; 95%CI, 1.23-2.13). Based on the data from a multicenter prospectively study, obesity was associated with a lower success rate on the first intubation attempt and a higher risk of adverse event in the ED.

Predictive performance of a multivariable difficult intubation model for obese patients.
A predictive model of scores of difficult intubation (DI) may help physicians screen for airway difficulty to reduce morbidity and mortality in obese patients. The present study aimed to set up and evaluate the predictive performance of a newly developed, practical, multivariate DI model for obese patients. ⋯ The predictive performance of the selected model showed limited benefit for preoperative screening to predict DI among obese patients.

Multicenter StudyEstablishing Decision Trees for Predicting Successful Postpyloric Nasoenteric Tube Placement in Critically Ill Patients.
Despite the use of prokinetic agents, the overall success rate for postpyloric placement via a self-propelled spiral nasoenteric tube is quite low. ⋯ Both the CHAID and LR models achieved an acceptable discrimination for predicting successful postpyloric nasoenteric tube placement and were useful for intensivists in the setting of self-propelled spiral nasoenteric tube insertion.
