To assess the impact of intraoperative hemodynamics in the development of perioperative myocardial infarction (MI) and myocardial ischemia after noncardiac surgery. ⋯ Low SAS scores (0-4) may be associated with cTn elevation after noncardiac surgery. SAS-based risk stratification may guide perioperative cTn surveillance in lieu of routine postoperative screening.

To determine the effect of body mass index (BMI) on the relationship of the popliteal artery to the sciatic and tibial nerves in the popliteal fossa. ⋯ At 5 cm proximal to the distal femoral condyles, the popliteal artery is a reliable sonographic landmark to locate the tibial nerve due to the close proximity and consistent location of the nerve 1 cm posterolateral to the artery, with only a moderate effect of BMI.

Nasotracheal intubation can be both challenging and traumatic, especially in cases of atypical anatomy. We present a series of 3 such cases in which an endotracheal tube introducer (bougie) was used to facilitate successful, atraumatic, nasotracheal intubation via Seldinger technique. The technique described can guide a nasotracheal tube through narrow nasal passages, small pharyngeal spaces, and past acute laryngeal approach angles, all without transoral manipulation of the tube. The technique is easy to perform, uses a routine skill set, and can be advantageous in numerous clinical scenarios.

Colonoscopy is widely performed for the diagnosis and treatment of various colonic disorders and the screening and surveillance of colorectal neoplasia. According to research evidence, up to one-third of patients had at least 1 minor and transient gastrointestinal symptom after colonoscopy. ⋯ Here, we present the case of a 95-year-old man with chronic obstructive pulmonary disease who developed bilateral tension pneumothorax during therapeutic colonoscopy for sigmoid volvulus. In this case, air trapping resulting from the Valsalva maneuver under inadequate pain control may be the mechanism for fatal tension pneumothorax during colonoscopy.
