Comparison of Monotherapy Versus Combination of Intravenous Ibuprofen and Propacetamol (Acetaminophen) for Reduction of Postoperative Opioid Administration in Children Undergoing Laparoscopic Hernia Repair
AUTHORS: Lee, Hye-Mi MD et al Anesthesia & Analgesia: November 2020 BACKGROUND: Extensive efforts have been made toward reducing postoperative opioid use in children. In this study, we assessed whether propacetamol, or a nonsteroidal anti-inflammatory drug (NSAID), or their combination could effectively reduce opioid use in children after laparoscopic inguinal hernia repair. METHODS: This randomized, […]
“Silent” Presentation of Hypoxemia and Cardiorespiratory Compensation in COVID-19
Authors: Philip E. Bickler, M.D., Ph.D.et al Anesthesiology February 2021, Vol. 134, 262–269. The Coronavirus infection disease 2019 (COVID-19) pandemic is bringing unprecedented numbers of patients with significant hypoxemia to medical care. It is critical that clinicians caring for hypoxemic patients recognize two facts: (1) it is common for hypoxemia to exist without dyspnea (“silent hypoxia”); […]
Clinical Effectiveness of Liposomal Bupivacaine Administered by Infiltration or Peripheral Nerve Block to Treat Postoperative Pain
Authors: Brian M. Ilfeld, M.D., M.S. et al Anesthesiology February 2021, Vol. 134, 283–344. The authors provide a comprehensive summary of all randomized, controlled trials (n = 76) involving the clinical administration of liposomal bupivacaine (Exparel; Pacira Pharmaceuticals, USA) to control postoperative pain that are currently published. When infiltrated surgically and compared with unencapsulated bupivacaine or […]
Application of a High-Flow Nasal Cannula for Prevention of Postextubation Atelectasis in Children Undergoing Surgery
AUTHORS: Lee, Ji-Hyun MD, PhD et al Anesthesia & Analgesia: November 2020 BACKGROUND: General anesthesia-induced atelectasis is common, and persistent postoperative atelectasis is associated with pulmonary complications. We aimed to evaluate the preventive effects of a high-flow nasal cannula (HFNC) on postoperative atelectasis and respiratory complications in infants and small children. METHODS: In this prospective […]

METHODS: Participants in this longitudinal analysis were children ages 2–12 undergoing tonsillectomy with or without adenoidectomy and their parents. Parents […]
Rifampin Reduces the Plasma Concentrations of Oral and Intravenous Hydromorphone in Healthy Volunteers
AUTHORS: Lohela, Terhi J. MD, PhD et al Anesthesia & Analgesia: November 2020 BACKGROUND: Several opioids are metabolized by the inducible cytochrome P450 (CYP) 3A isozymes. Coadministration with strong inducers of drug metabolism, such as rifampin, can dramatically reduce systemic exposure to these opioids. As the CYP metabolism of hydromorphone is of minor importance, we […]
Intraoperative Hypotension Is Associated With Adverse Clinical Outcomes After Noncardiac Surgery
AUTHORS: Gregory, Anne MD, MSc, FRCPC et al Anesthesia & Analgesia: November 2020 BACKGROUND: Intraoperative hypotension (IOH) occurs frequently during surgery and may be associated with organ ischemia; however, few multicenter studies report data regarding its associations with adverse postoperative outcomes across varying hemodynamic thresholds. Additionally, no study has evaluated the association between IOH exposure […]
