Background: Perioperative respiratory adverse events remain a major cause of postoperative morbidity and mortality during pediatric anesthesia. This multicenter study was designed to evaluate the incidence of perioperative respiratory adverse events during elective pediatric surgery and to identify the risk factors for these events. Methods: Pediatric patients undergoing elective surgery under general anesthesia in 11 hospitals were randomly selected for this prospective, multicenter study. Preanesthetic assessments, anesthetic and surgical conditions were recorded by anesthesiologists in charge. Adverse respiratory events were registered. Results: Eight hundred and twenty-three patients were included. The overall incidence of any perioperative respiratory adverse respiratory event was 15.1%. The incidences of perioperative bronchospasm, laryngospasm, coughing, desaturatioin (oxygen saturation <95%), and airway obstruction were 0.1, 0.5, 10.2, 4.1,and 1.6% respectively. According to the multivariate analysis, five risk factors were identified: multiple attempts for airway device insertion, odds ratio (OR) 2.88; recent URI (≤2 weeks), OR 1.96;induction with intravenous anesthetics, OR 1.95; airway related surgery, OR 1.88; ASA class ≥2, OR 1.62. Conclusions: Multiple attempts for airway device insertion, recent URI, induction with intravenous anesthetics, airway related surgery and ASA class ≥2 were associated with increased risk for perioperative respiratory adverse events.

Pulmonary alveolar proteinosis (PAP) is characterized by the progressive accumulation of phospholipids and proteins within the alveolar sacs without producing an inflammatory response. Whole-lung lavage (WLL) is performed as the standard therapy for this disease because it serves to wash out the proteinaceous material from the alveoli. In this case, we performed sequential WLL using propofol-remifentanil, which is not related to hypoxic pulmonary vasoconstriction during one-lung ventilation. The patient's symptoms and radiologic findings showed improvement without the occurrence of any specific complications. Therefore, we report a case of anesthetic management of WLL performed repeatedly for a patient with recurrent PAP.

Bioaerosols are airborne particles of biological origins including viruses, bacteria, fungi, and all varieties of living materials. In suitable hosts, bioaerosols are capable of causing acute or chornic diseases that may be infectious, allergenic, or toxigenic. Bioaerosols from outdoor air accumulate on filters of heating, ventilating and air conditioning (HVAC) system in large quantities and are able to multiply there under certain conditions. In this study, silver was coated on activated carbon fiber (ACF) filters by an electroless plating method, and their efficacy for bioaerosols removal was tested. Physical filtration and biological antimicrobial test were performed. SEM and XRD analyses were used to characterize the morphology and components of ACF filters. Electroless silver-plated ACF filters showed antimicrobial efficiency, whereas pure ACF filters did not. It was found that electroless silver plating did not influence the physical filtration efficiency of ACF filters.
