Randomized Controlled TrialThe effect of head position on glottic visualization with video laryngoscope and intubation success in obese patients who are not expected to have a difficult airway: a prospective randomized clinical study.
Intubation is required to maintain anesthesia in patients who are planned to undergo surgery under general anesthesia. One of the most important steps for successful intubation is to position head and neck appropriately. Sniffing position, head extension position, and neutral head position are the most known and used head and neck positions. ⋯ IDS score was found to be statistically significantly higher in the neutral head position compared to the other positions (p < 0.001, p < 0.001, respectively). In addition, the IDS score was statistically significantly higher in head extension position than in sniffing position (p = 0.016). This study is a randomized controlled trial of 150 patients investigating the impact of head position on glottic visualization and intubation success in obese patients when using Macintosh-like VL. The results show that sniffing position may be favored.

Randomized Controlled Trial
Point-of-care ultrasonography-assisted nasogastric tube placement in the emergency department: a randomized controlled trial.
The complications of a blind procedure for gastric tube placement are well documented. POCUS has been widely used to confirm the position of blindly inserted gastric tubes, and it does not prevent complications caused by the blind method. We performed a randomized controlled trial to compare gastric tube insertion with real-time oesophagus visualization using POCUS to the standard technique. ⋯ POCUS enables real-time insertion of a gastric tube with high sensitivity, in a short time with high first-attempt success rate and limited passage-related complications. POCUS should be utilized for NGT insertion whenever expertise is available on the bedside.

Obesity, defined by the World Health Organization as body mass index (BMI) ≥ 30.0 kg/m2, is associated with adverse outcomes and challenges during surgery. Difficulties during endotracheal intubation, occur in 3-8% of procedures and are among the principal causes of anesthetic-related morbidity and mortality. Endotracheal intubation can be challenging in obese patients due to an array of anatomic and physiologic factors. Double lumen tubes (DLTs), the most commonly used airway technique to facilitate anatomic isolation of the lungs for one lung ventilation. However, DLTs can be difficult to properly position and are also more likely to cause airway injuries and bleeding when compared to conventional single lumen tubes. We investigated the association between BMI and difficult tracheal DLT intubation. ⋯ Difficult intubations with DLT remain common, but BMI is a weak predictor thereof. For example, an increase in BMI from 20 to 40 kg/m2 corresponds to an increase in average absolute risk for difficult intubation from 16 to 19%, which probably is not clinically meaningful.

Across multiple disciplines undertaking airway management globally, preventable episodes of unrecognised oesophageal intubation result in profound hypoxaemia, brain injury and death. These events occur in the hands of both inexperienced and experienced practitioners. Current evidence shows that unrecognised oesophageal intubation occurs sufficiently frequently to be a major concern and to merit a co-ordinated approach to address it. ⋯ The tube should be removed if timely restoration of sustained exhaled carbon dioxide cannot be achieved. In addition to technical interventions, strategies are required to address cognitive biases and the deterioration of individual and team performance in stressful situations, to which all practitioners are vulnerable. These guidelines provide recommendations for preventing unrecognised oesophageal intubation that are relevant to all airway practitioners independent of geography, clinical location, discipline or patient type.
