Interventional pulmonology is a growing subspecialty of pulmonary medicine with flexible and rigid bronchoscopies increasingly used by interventional pulmonologists for advanced diagnostic and therapeutic purposes. This review discusses different technical aspects of anesthesia for interventional pulmonary procedures with an emphasis placed on pharmacologic combinations, airway management, ventilation techniques, and common complications. ⋯ It is fundamental for the anesthesia provider to be updated on interventional pulmonology procedures in this rapidly growing area of medicine.

Comparative Study Observational Study
The effects of systemic oxygenation on cerebral oxygen saturation and its relationship to mixed venous oxygen saturation: A prospective observational study comparison of the INVOS and ForeSight Elite cerebral oximeters.
The present study aimed to test the hypothesis that cerebral oxygen saturation (ScO2) measurements with the INVOS-5100-C and the ForeSight-Elite cerebral oximeters vary in their correlation with mixed venous oxygen saturation (SvO2) upon changes in systemic oxygenation in extubated cardiac surgical patients. Additionally, we aimed to elucidate whether the ScO2 measurements of both devices can be used interchangeably to detect reduced SvO2. ⋯ These findings suggest that the cerebral oximeters tested react differently to variations in systemic oxygenation and in their relationship with SvO2 and thus give different information on cardiopulmonary function. These findings raise doubt about whether these devices should be used interchangeably.

The influence of obesity on anesthetic risk remains controversial, and obesity has only recently been specifically identified as a criterion by which a patient can be given a higher American Society of Anesthesiologists-physical status (ASA-PS) score. Nevertheless, we hypothesized that clinicians had assigned obese patients a greater ASA-PS score before obesity became an "official" criterion in 2015. ⋯ These findings suggest a consistent and temporally stable practice of up-coding obese patients despite this lack of explicit guidance. The ASA House of Delegates' recent decision to specifically mention obesity reinforces long-existing practices regarding ASA-PS coding and will likely not degrade the validity of data sets collected before the change.
