unusual cause of post-operative orbital edema in a child after general anesthesia

We present an unusual ocular complication during the perioperative period, bilateral orbital edema in an otherwise healthy child after an outpatient surgical procedure. Ocular complications under general anesthesia remain a rare event. When periorbital edema is present, the appropriate work-up includes ruling out the potential for an allergic event by reviewing the medications administered and serum tryptase testing. Ophthalmology consultation should be considered to exclude pathology native to the eye itself. An allergist may assist in confirming a diagnosis and for allergic testing, if indicated. In our patient, the eventual diagnosis of exclusion was that of a localized reaction to the cellophane-based eye tape

Postoperative hypoxemia due to fat embolism

Although the reported incidence of fat embolism syndrome [FES] is low [approximately 1%], it is likely that microscopic fat emboli are showered during manipulation of long bone fractures. Even though there continues to be debate regarding the etiology and proposed mechanism responsible for FES, significant systemic manifestations may occur. Treatment is generally symptomatic based on the clinical presentations. We report a 10-year-old girl who developed hypoxemia following treatment of a displaced Salter-Harris type II fracture of the distal tibia. The subsequent evaluation and hospital course pointed to fat embolism as the most likely etiology for the hypoxemia. We discuss the etiology for FES, review the proposed pathophysiological mechanisms responsible for its clinical manifestations, present currently accepted diagnostic criteria, and discuss its treatment
