Key components of a community response to out-of-hospital cardiac arrest.

Nat Rev Cardiol 2019 Mar 11. Epub 2019 Mar 11.

Department of Anesthesiology and Critical Care Medicine, The Children's Hospital of Philadelphia, University of Pennsylvania Perelman School of Medicine, Philadelphia, PA, USA.

Out-of-hospital cardiac arrest (OHCA) remains a leading cause of death worldwide, with substantial geographical, ethnic and socioeconomic disparities in outcome. Successful resuscitation efforts depend on the 'chain of survival', which includes immediate recognition of cardiac arrest and activation of the emergency response system, early bystander cardiopulmonary resuscitation (CPR) with an emphasis on chest compressions, rapid defibrillation, basic and advanced emergency medical services and integrated post-cardiac arrest care. Well-orchestrated telecommunicator CPR programmes can improve rates of bystander CPR - a critical link in the chain of survival. Read More

Validation of APLS, Argall and Luscombe Formulae for Estimating Weight among Indian Children.

Indian J Pediatr 2019 Mar 7. Epub 2019 Mar 7.

Division of Community Studies, ICMR-National Institute of Nutrition, Hyderabad, India.

Weight estimation in pediatric emergencies is often required for calculation of drug dosages, fluid therapy and defibrillation. The 'gold standard' of actually weighing the patient is not practically possible in emergency conditions. The aim of this study is to validate common age-based formulae (APLS, Luscombe and Argall's) and their accuracy in estimating weight of under 5-y-old Indian children by secondary data analysis from a cross-sectional study conducted by the National Nutrition Monitoring Bureau (NNMB), National Institute of Nutrition, Hyderabad, in 10 states of India in 2011-12 among under five-year-old children.

Simultaneous leadless pacemaker and subcutaneous implantable cardioverter-defibrillator implantation-When vascular options have run out.

J Arrhythm 2019 Feb 20;35(1):136-138. Epub 2018 Nov 20.

National Heart Centre Singapore Singapore.

An end-stage renal failure patient who was planned for a left brachioaxillary arteriovenous graft required an implantable cardioverter-defibrillator for secondary prevention of ventricular tachycardia and a pacemaker for complete heart block but was found to have a right subclavian venous occlusion. Due to the lack of vascular access, we performed a successful subcutaneous implantable cardioverter-defibrillator (S-ICD) and leadless pacemaker implantation. There was no interaction between the devices at the time of implantation, during defibrillation testing and following an appropriate defibrillation therapy. Read More

Leakage current from transvenous and subcutaneous implantable cardioverter defibrillators (ICDs): A risk to the rescuer?

Resuscitation 2019 Feb 19;137:148-153. Epub 2019 Feb 19.

NIHR Respiratory BRU, University Hospital Southampton, Southampton SO16 6YD, UK. Electronic address:

Background Implantable cardioverter-defibrillators (ICDs) are a well-established therapy for patients at risk of life-threatening ventricular arrhythmias. With rising implant rates, the risk of a rescuer performing chest compressions during discharge is increasing, leading to concerns over rescuer safety from the resultant leakage current. More recently, subcutaneous ICDs (S-ICD) have been developed, which utilise a higher energy and more superficial electrodes compared with transvenous ICDs (T-ICD), raising safety concerns further.

Survival to hospital discharge with biphasic fixed 360 joules versus 200 escalating to 360 joules defibrillation strategies in out-of-hospital cardiac arrest of presumed cardiac etiology.

Resuscitation 2019 Mar 29;136:112-118. Epub 2019 Jan 29.

Norwegian National Advisory Unit on Prehospital Emergency Medicine, Oslo University Hospital, Oslo, Norway. Electronic address:

Introduction: Guidelines recommend constant or escalating energy levels for shocks after the initial defibrillation attempt. Studies comparing survival to hospital discharge with escalating vs fixed high energy level shocks are lacking. We compared survival to hospital discharge for 200 J escalating to 360 J vs fixed 360 J in patients with initial ventricular fibrillation/pulseless ventricular tachycardia in a post-hoc analysis of the Circulation Improving Resuscitation Care trial database.

Kinetic changes in cellulose properties during defibrillation into microfibrillated cellulose and cellulose nanofibrils by ultra-refining.

Int J Biol Macromol 2019 Apr 29;127:637-648. Epub 2019 Jan 29.

Biocatalysis and Bioproducts Laboratory, Department of Biotechnology - Lorena School of Engineering, University of São Paulo, Lorena, SP 12602-810, Brazil. Electronic address:

Defibrillation of cellulose fibers can lead to the isolation of microfibrillated cellulose (MFC) or cellulose nanofibrils (CNF) with intrinsic properties suitable for various applications. However, to what extent these properties are preserved, enhanced, gained or lowered during defibrillation and how they are related remains unclear. In this study, a kinetic study of the ultra-refining of bleached eucalyptus Kraft pulp (BEKP) in a disc ultra-refiner was performed and characterized in terms of physical-structural, morphological and thermal properties and their interactions and compromises.

Coronary artery spasm induced by carotid sinus stimulation during arthroscopic shoulder surgery: A case report.

Medicine (Baltimore) 2019 Feb;98(5):e14352

Department of Anesthesiology and Pain Medicine, Soonchunhyang University, Seoul Hospital, Seoul, Republic of Korea.

Rationale: Variant angina is characterized by coronary artery spasm irrespective of the presence of fixed stenotic coronary lesions. Perioperative coronary artery spasm may be induced by the supersensitivity of vascular smooth muscle cells caused by various stimuli, including stimulation of the parasympathetic nervous system.

Patient Concerns: A 57-year-old male patient was undergoing arthroscopic rotator cuff repair under combined interscalene brachial plexus block and general anesthesia in the lateral decubitus position. Read More

Amiodarone-induced life-threatening torsade de pointes in an end-stage lung cancer patient receiving gefitinib.

Oxf Med Case Reports 2019 Jan 24;2019(1):omy122. Epub 2019 Jan 24.

Department of Cardiovascular Medicine, First Hospital of Xi'an Jiaotong University, 277 Yanta West Road, Xi'an, China.

The risk factors of acquired long QT syndrome (aLQTS) are sometimes overlooked in clinics. Drugs, hypokalemia, age and female sex are well-known risk factors of QT prolongation-dependent torsade de pointes (TdP), which explains the high incidence of sudden cardiac death in LQT patients. Here, we report a case of an elderly female patient with lung cancer who was in poor condition, for whom amiodarone was mistakenly prescribed to rectify premature ventricular contractions. Read More
