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.

Postdural puncture headache (PDPH) is the most common symptom of accidental dural puncture, a frequent complication of intraspinal anesthesia. We developed a postoperative intervention technique to prevent and treat PDPH in accidental dural puncture patients, including epidural pumping of saline. This retrospective study aimed to retrospectively evaluate this new technique for PDPH prevention and treatment. ⋯ Our data indicated that application of 6mL/h saline effectively contributes to PDPH management, and its clinical application should be broadened.

To investigate the effects of dexmedetomidine on oxidative injury caused by ionizing radiation. ⋯ Dexmedetomidine preserves the antioxidant enzyme levels and reduces toxic oxidant metabolites. Therefore, it can provide protection from oxidative injury caused by ionizing radiation.
