Treatment of bronchial foreign body aspiration with extracorporeal life support in a child: A case report and literature review.

We present a case in which extracorporeal life support treatment of a 6-year-old girl asphyxiated by aspiration of an elliptic plastic ball is described. The attempts for extraction of the foreign body by conventional bronchoscopy under critically ill conditions had failed. Thus, a skin incision was made in the midline, and an emergency open-chest cardiopulmonary […]

Delayed bilateral vocal cord paresis after a continuous interscalene brachial plexus block and endotracheal intubation: A lesson why we should use low concentrated local anesthetics for continuous blocks.

Recurrent laryngeal nerve block is an uncommon complication that can occur after an interscalene brachial plexus block (ISB), which may lead to vocal cord palsy or paresis. However, if the recurrent laryngeal nerve is blocked in patients with a preexisting contralateral vocal cord palsy following neck surgery, this may lead to devastating acute respiratory failure. […]

Propofol vs. Alfentanil for Moderate Procedural Sedation

Authors: Miner JR et al., Am J Emerg Med 2017 Apr 21; Frequency of adverse events was similar, but fewer propofol patients reported pain or memory of the procedure. Alfentanil is an ultrashort-acting opioid that induces analgesia for 7 to 9 minutes. In a single-blind (patient blinded), randomized, controlled trial, investigators at an urban county medical center […]

Incidence of Pulmonary Embolism Diagnosed by Ventilation and Perfusion Scan After Indeterminate CT Pulmonary Angiography

Authors: Curtis BR et al., Emerg Radiol 2017 Apr 12; VQ scan rarely identifies pulmonary embolism after indeterminate computed tomography pulmonary angiography. Investigators studied the incidence of pulmonary embolism (PE) diagnosed by ventilation and perfusion (VQ) scan after suboptimal computed tomography pulmonary angiography (CTPA). They retrospectively analyzed data from one academic institution that used modified prospective investigation of […]

Risks of Cardiovascular Adverse Events and Death in Patients with Previous Stroke Undergoing Emergency Noncardiac, Nonintracranial Surgery: The Importance of Operative Timing

Authors: Mia N. Christiansen, M.D. et al Anesthesiology published on May 18, 2017. Background: The outcomes of emergent noncardiac, nonintracranial surgery in patients with previous stroke remain unknown. Methods: All emergency surgeries performed in Denmark (2005 to 2011) were analyzed according to time elapsed between previous ischemic stroke and surgery. The risks of 30-day mortality and major adverse […]

Intra-Articular Corticosteroids Show No Benefit in Knee Osteoarthritis

Edited by David G. Fairchild, MD, MPH, and Lorenzo Di Francesco, MD, FACP, FHM Intra-articular triamcinolone does not help relieve knee pain in adults with osteoarthritis — and might even lead to harm — according to a placebo-controlled trial in JAMA. Some 140 adults with symptomatic knee osteoarthritis and ultrasound evidence of synovitis were randomized to receive intra-articular […]

Video Laryngoscopes and Best Rescue Strategy for Unexpected Difficult Airways: Do Not Forget a Combined Approach with Flexible Bronchoscopy!

Authors: Filippo Sanfilippo, M.D., Ph.D. et al Anesthesiology 6 2017, Vol.126, 1203 To the Editor: Asai1  describes the issue of the unexpected difficult airways, recommending to avoid repeated attempts and to seek an effective alternative strategy early. Based on the results of Aziz et al.,2  Asai suggests that video laryngoscopy may represent the best rescue alternative and that a […]

An Allometric Model of Remifentanil Pharmacokinetics and Pharmacodynamics

Authors: Douglas J. Eleveld, Ph.D. et al Anesthesiology 6 2017, Vol.126, 1005-1018. Background: Pharmacokinetic and pharmacodynamic models are used to predict and explore drug infusion schemes and their resulting concentration profiles for clinical application. Our aim was to develop a pharmacokinetic-pharmacodynamic model for remifentanil that is accurate in patients with a wide range of age and weight. […]

Remifentanil Dosing at Extremes of Body Weight

Authors: Steven L. Shafer, M.D. et al Anesthesiology 6 2017, Vol.126, 993-994. ANESTHESIOLOGISTS are expected to be equally competent treating a 5-kg child and a 250-kg adult. For infused drugs, such as remifentanil, this means selecting an initial infusion rate appropriate for the patient. A practice we have observed is to set a dose that is […]

Effect of Dexmedetomidine and Propofol on Basal Ganglia Activity in Parkinson Disease: A Controlled Clinical Trial

Authors: Antonio Martinez-Simon, M.D., Ph.D. et al Anesthesiology 6 2017, Vol.126, 1033-1042 Background: Deep brain stimulation electrodes can record oscillatory activity from deep brain structures, known as local field potentials. The authors’ objective was to evaluate and quantify the effects of dexmedetomidine (0.2 μg·kg-1·h-1) on local field potentials in patients with Parkinson disease undergoing deep brain stimulation […]
