Fire in the operating room is a rare but potentially devastating event. In this case report, we describe 2 separate fires of a Westmed heated humidification circuit. We conducted a detailed analysis of potential causes of the fires, including a simulation and series of experiments. Our conclusions were (1) a combination of factors led to the fires; and (2) substantial changes in the design could decrease, but may not completely eliminate, the risk of operating room fire.

Background: Double outlet right ventricle (DORV) is a challenging congenital cardiac lesion to surgically master. We utilize computed tomography-guided-three-dimensional (3D) modeling/printing and novel in-house software to delineate anatomical relationships providing operative insight into the surgical approach. Our intent is to highlight this and showcase our technology.

Objective: Intracerebral hemorrhage (ICH) is a common cerebrovascular disease characterized by high mortality and disability rates. Neuritin, significantly expressed in injured brain tissues, is implicated in the molecular mechanisms underlying acute brain injury. We aimed to explore the prognostic and predictive value of serum neuritin in ICH.

Background: Breast reconstruction with the deep inferior epigastric perforator (DIEP) free flap has become the gold standard for autologous breast reconstruction. Flap take-back to the operating room (OR) is an uncommon but difficult situation, requiring prompt and accessible resources. We conducted a literature review and independent expert review to inform evidence-based perioperative algorithms in the event of DIEP flap compromise.
