Review Case ReportsInterpreting the results of early skin tests after perioperative anaphylaxis requires special attention: a case report and review of literature.
Skin tests are the gold standard for detecting the culprit drug of anaphylaxis, and should ideally be performed after an interval of 4-6 weeks after the reaction to avoid false-negative results. However, when re-operation cannot be delayed and early allergy tests are necessary, special attention is required during subsequent anesthesia, because early skin tests tend to produce false-negative results. This report presents a case of rocuronium-induced anaphylaxis in which early skin tests showed negative results for all the drugs tested. ⋯ In this report, we also discuss interpretation of the results of early skin tests and subsequent selection of drugs for anesthesia. After postponement of surgery due to anaphylaxis, we are often required to perform allergy tests at an early stage if re-operation cannot be delayed. In such cases, skin test results alone should not be used to guide subsequent anesthesia management to avoid recurrent anaphylaxis.

Surgical smoke generated by use of electrosurgical units (ESUs), lasers, and ultrasonic scalpels constitutes a physical, chemical, and biological hazard for anesthesia personnel. Inhalation of particulate matter with inflammatory consequences, pulmonary injury from products of tissue pyrolysis, exposure to mutagens and carcinogens, and the transmission of human papillomavirus (HPV) and possibly other pathogens represent a spectrum of adverse effects associated with the occupational exposure to surgical plume. ⋯ SED use is relatively infrequent in most surgeries, and this condition reflects surgeons' reluctance to employ these devices, likely resulting from lack of education and less than optimal technology. Anesthesia societies and academic centers can serve critical roles in advocating employment of SEDs in much the same way that they have supported perioperative smoking cessation.

ReviewA "crush" course on rhabdomyolysis: risk stratification and clinical management update for the perioperative clinician.
Rhabdomyolysis, the release of myoglobin and other cellular breakdown products from necrotic muscle tissue, is seen in patients with crush injuries, drug overdose, malignant hyperthermia, muscular dystrophy, and with increasing frequency in obese patients undergoing routine procedures. For the perioperative clinician, managing the resultant shock, hyperkalemia, acidosis, and myoglobinuric acute kidney injury can present a significant challenge. Prompt recognition, hydration, and correction of metabolic disturbances may reduce or eliminate the need for long-term renal replacement therapy. This article reviews the pathophysiology and discusses key issues in the perioperative diagnosis, risk stratification, and management of rhabdomyolysis.

ReviewReview 1: Lung transplant-from donor selection to graft preparation.
For various end-stage lung diseases, lung transplantation remains one of the only viable treatment options. While the demand for lung transplantation has steadily risen over the last few decades, the availability of donor grafts is limited, which have resulted in progressively longer waiting lists. ⋯ Due to the donor shortages, there is ongoing discussion about the safe use of 'suboptimal' grafts to expand the donor pool. In this review, we will discuss the considerations around donor selection, donor-recipient matching, graft preparation and graft optimisation.
