Comparison of airway assessment tests for prediction of difficult intubation in obese patients: importance of thyromental height and upper lip bite test.
Prediction of difficult intubation (DI) has remained challenging for anesthesiologists and validity of airway assessment tests has not been fully investigated. This study aims to compare predictive values of these tests for prediction of DI in obese patients. ⋯ TMH and ULBT had the highest sensitivity for prediction of DI in obese patients in this study and it is recommended to be considered as part of airway assessment in this patient population.

Randomized Controlled Trial
Clinical evaluation of the use of laryngeal tube verses laryngeal mask airway for out-of-hospital cardiac arrest by paramedics in Singapore.
It remains unclear which advanced airway device has better placement success and fewer adverse events in out-of-hospital cardiac arrests (OHCAs). This study aimed to evaluate the efficacy of the VBM laryngeal tube (LT) against the laryngeal mask airway (LMA) in OHCAs managed by emergency ambulances in Singapore. ⋯ LT was associated with poorer placement success and higher complication rates than LMA. The likelihood of prehospital ROSC was similar between the two groups. Familiarity bias and a low compliance rate to LT were the main limitations of this study.

Different introducers are available to assist with tracheal intubation. Subtle differences in the design of introducers can have a marked effect on safety and performance. The Difficult Airway Society's Airway Device Evaluation Project Team proposal states that devices should only be purchased for which there is at least a case-control study on patients assessing airway devices. ⋯ Median time to successful placement in the trachea varied from 9 s (Frova) to 22 s (Armstrong) (p = 0.037). We found that the Armstrong and P3 devices were not as acceptable as other introducers and, without significant improvements to their design and characteristics, the use of these devices in studies on patients is questionable. The study protocol is suitable for differentiating between different introducers and could be used as a basis for assessing other types of devices.

General anaesthesia is associated with higher maternal morbidity and mortality when compared with regional anaesthesia, related mainly to failure of intubation, hypoxia and aspiration. The aim of this retrospective review was to define the incidence of failed and difficult intubation in parturients undergoing general anaesthesia for Caesarean delivery at a high-volume obstetric hospital in Singapore. ⋯ The local incidence of difficult obstetric intubation was one in 20. No failure of intubation was observed.

Endotracheal intubation is a lifesaving procedure frequently performed in emergency departments. It is associated with some potential risks. Rapid and reliable confirmation of endotracheal tube placement during intubation is critical. Nurses play an important role in the care of patients in various settings. Ultrasound can be performed and interpreted not only by physicians but also by nurses. The aim of this study was to evaluate how well nurses without previous ultrasound experience can determine both esophageal and tracheal localization of endotracheal tubes in cadavers after a short ultrasound training. ⋯ The results support that ultrasound can be performed by nurses for the confirmation for esophageal and tracheal intubations quickly and accurately.
