Severe Acute Lung Injury After H2O2 Irrigation of an Aneurysmal Bone Cyst in an 8-Year-Old Girl: A Case Report.
An 8-year-old girl developed severe acute lung injury after irrigation of a pelvic aneurysmal bone cyst with H2O2 and filling with bone cement. Sudden profound oxygen desaturation occurred on the operating table when the patient was turned from the prone to the supine position. ⋯ The patient started to improve after 24 hours and eventually made a full recovery. We hypothesize that the incident was caused by gas embolization and pulmonary endothelial damage by H2O2.

Potential Patent Blue V Overdose in a Patient Undergoing Free-Flap Breast Reconstruction: A Case Report.
The case of a patient who experienced serious adverse effects following a potential overdose of Patent Blue V dye (PVB) is presented here. A 65-year-old woman developed cardiac arrythmias and circulatory instability 35 minutes after receiving 100 mg PVB during breast cancer surgery. ⋯ However, mast-cell tryptase levels were normal and subsequent allergy testing for all potential allergens was negative. This case highlights that life-threatening reactions to perioperative PVB should not always be attributed to anaphylaxis; systemic toxicity could occur with an overdose.

The risk of aerosol transmission has been a key factor for the rapid dissemination of the coronavirus pandemic. Transportation of coronavirus disease 2019 (COVID-19)-infected patients with active air leaks could expose unprotected health care personnel and other patients to aerosolized viral particles. ⋯ It involves placing an Ultipor100 viral filter on the suction port of the drain system as well as sealing off the safety valve. This mechanism allows positive pressure from an air leak to escape while on water seal while trapping viral particles.

There is an increasing impetus to perform primary total hip arthroplasty and total knee arthroplasty on an outpatient basis and in the outpatient setting. However, with recent federal regulatory changes, orthopedic surgeons must now evaluate patients on a case-by-case basis to determine whether an inpatient admission will be medically necessary and appropriate. We thus created our prototype Lower Extremity Inpatient-Outpatient (LET-IN-OUT) total joint replacement tool as a simple, consistent way for other clinicians to identify specific major preoperative patient comorbidities and thus to recommend independently and objectively to the orthopedic surgeon postoperative inpatient or outpatient status for a given patient.

Paragangliomas (PGLs) are rare tumors with an incidence of 0.007% in pregnant women. Patients with PGLs commonly present with hypertension and tachycardia. This case report describes the evaluation and management of a multiparous woman at 32 weeks of gestation with syncope, hypoxia, and tachycardia as unusual presenting symptoms of PGL. Her symptoms were attributable to paradoxical effects of circulating catecholamines on downregulated alpha-adrenergic receptors resulting in decreased systemic vascular resistance.
