Observational Study
Monitoring Transcutaneously Measured Partial Pressure of CO2 During Intubation in Critically Ill Subjects.
The risk for severe hypoxemia during endotracheal intubation is a major concern in the ICU, but little attention has been paid to CO2 variability. The objective of this study was to assess transcutaneously measured partial pressure of CO2 ([Formula: see text]) throughout intubation in subjects in the ICU who received standard oxygen therapy, high-flow nasal cannula oxygen therapy, or noninvasive ventilation for preoxygenation. We hypothesized that the 3 methods differ in terms of ventilation and CO2 removal. ⋯ [Formula: see text] variability during intubation is significant and differs with the method of preoxygenation. A decrease in [Formula: see text] after the beginning of mechanical ventilation was associated with postintubation hypotension. (ClinicalTrials.gov registration NCT0388430.).

In children who have craniofacial asymmetry secondary to neurofibromatosis type 1, the securing of the airway can be challenging. These patients have varying degrees of head and neck tumors that complicate endotracheal intubation. Anesthesiologists have many techniques and devices that assist us in securing adult airways and these devices are available in pediatric sizes which can also be used to safely secure the smaller airways. ⋯ This is a case report of improvement of intubating conditions using both devices concurrently.

Patient barrier acceptance during airway management among anesthesiologists: a simulation pilot study.
Protection of healthcare providers (HCP) has been a serious challenge in the management of patients during the coronavirus 2019 (COVID-19) pandemic. Additional physical barriers have been created to enhance personal protective equipment (PPE). In this study, user acceptability of two novel barriers was evaluated and the performance of airway management using PPE alone versus PPE plus the additional barrier were compared. ⋯ Overall, the IC and AB were comparable, and there was no negative impact on performance under testing conditions. Our study suggests the positive acceptance of additional patient protection barriers by anesthesia providers during airway management.

During induction of general anaesthesia a 'cannot intubate, cannot oxygenate' (CICO) situation can arise, leading to severe hypoxaemia. Evidence is scarce to guide ventilation strategies for small-bore emergency front of neck airways that ensure effective oxygenation without risking lung damage and cardiovascular depression. ⋯ Dynamic hyperinflation can be demonstrated for a wide range of front of neck airway cannulae when the upper airway is obstructed. When using small-bore cannulae in a CICO situation, ventilation strategies should be chosen that prevent gas trapping to prevent severe adverse events including cardio-circulatory depression.
