PURPOSE: This case report outlines the utility and challenges of remote continuous postoperative electrocardiography ECG) monitoring, which is routed through a secure smartphone to provide real-time detection and management of myocardial ischemia. CLINICAL FEATURES: A 42-yr-old male with previous myocardial infarction and angioplasty underwent a radical prostatectomy. At three hours and 45 min postoperatively, remote real-time ECG monitoring was initiated upon the patient's arrival on a regular surgical ward...

PURPOSE: Nasotracheal intubation is a widely performed technique to facilitate anesthesia induction during oral, dental, and maxillofacial surgeries. The technique poses several risks not encountered with oropharyngeal intubation, most commonly epistaxis due to nasal mucosal abrasion. The purpose of this study was to test whether the use of the Parker Flex-Tip™ (PFT) nasal endotracheal tube (ETT) with a posterior facing bevel reduces epistaxis when compared with the standard nasal RAE ETT with a leftward facing bevel...

PURPOSE: Epidural anesthesia and analgesia has a reported failure rate ranging from 13% to 32%. We describe a technique using colour Doppler and M-mode ultrasonography to determine the position of the epidural catheter after placement in adults. METHODS: This retrospective review included 37 adult patients who received postoperative epidural analgesia and underwent technically difficult epidural catheter placement. The demographic characteristics, type of surgery, use of ultrasonography, method of insertion, intervertebral level, and success of epidural localization using colour Doppler were noted for each patient...

PURPOSE: To determine if a non-exercise algorithm-derived assessment of cardiorespiratory fitness (CRFA) accurately predicted estimated values obtained using a six-minute walk test (CRF6MWD) and the Duke Activity Status Index (CRFDASI). METHODS: Following research ethics board approval, an observational cohort study was conducted in selected, consenting patients undergoing elective surgery. Participants completed questionnaires assessing their self-reported exercise capacity...

PURPOSE: Malignant hyperthermia susceptibility (MHS) is a disorder of the regulation of calcium in skeletal muscle. Muscular individuals have been shown to have a 13.6-fold increased risk of death during malignant hyperthermia (MH) episodes and are more likely to experience a recurrence after initial treatment. Twenty-five percent of severe MH episodes have occurred in elite athletes. This study investigated the association between MHS and muscular body build. METHODS: Data were obtained from existing reports in the North American Malignant Hyperthermia Registry, including the Report of Muscle Biopsy and Contracture Testing (caffeine-halothane contracture test [CHCT]) as well as Adverse Metabolic or Muscular Reaction to Anesthesia (AMRA) reports...

PURPOSE: This article describes the functioning of the international drug control system, its integration into national legislation and policy, and the collective impact on access to medicines. SOURCE: We conducted a review of the three international drug control conventions, peer-reviewed articles, and grey literature known to the authors that describes national and international drug control systems and their impact on access to controlled medicines. This review was supplemented with literature derived from a structured search of MEDLINE(®) for articles relating to medical uses of ketamine in low- and middle-income countries conducted to strengthen an advocacy campaign...

David T Wong, Amanda J Yee, Siaw May Leong, Frances Chung
PURPOSE: During the process of tracheal intubation, patients are apneic or hypoventilating and are at risk of becoming hypoxemic. This risk is especially high in patients with acute or chronic respiratory failure and accompanying compromised respiratory reserve. To address this concern, apneic oxygenation can be administered during tracheal intubation to aid in maintaining arterial oxygen saturation. The objective of this narrative review is to examine the utilization of apneic oxygenation within the operating room, intensive care unit (ICU), emergency department, and pre-hospital settings and to determine its efficacy compared with controls...

BACKGROUND: Although intravenous dexamethasone prolongs the analgesic duration of interscalene brachial plexus block, it is uncertain whether this effect can be observed using lower doses of dexamethasone. This study evaluated the impact of intravenous dexamethasone (4 mg and 10 mg) on the analgesic duration of single-shot interscalene block after arthroscopic shoulder surgery. We hypothesized that both doses would prolong the analgesic duration compared with placebo. METHODS: This was a prospective double-blind randomized placebo-controlled study in patients undergoing elective arthroscopic shoulder surgery under regional anesthesia with a single-shot interscalene block (0...

PURPOSE: To present a case of mycobacterium infection transmitted through a heater-cooler unit during cardiac bypass surgery. CLINICAL FEATURES: A 63-yr-old woman with a past medical history of aortic coarctation repair in 1963 and a mechanical aortic valve replacement in 2010 was prescribed antibiotics and steroids at an outpatient care facility in September 2015 for symptoms of an upper respiratory tract infection. Four months later, she developed malaise and intermittent fever with anemia and acute kidney dysfunction...

BACKGROUND: The primary aim of this study was to evaluate the effect of acute administration of L-carnitine 100 mg·kg(-1) iv on susceptibility to bupivacaine-induced cardiotoxicity in rats. METHODS: In the first of two experiments, L-carnitine 100 mg·kg(-1) iv (n = 10) or saline iv (n = 10) was administered to anesthetized and mechanically ventilated Sprague-Dawley rats following which an infusion of bupivacaine 2.0 mg·kg(-1)·min(-1) iv was given until asystole occurred...

PURPOSE: Skill acquisition in direct laryngoscopy (DL) and tracheal intubation is complex. This pilot study aims to assess feasibility and determine sample size for a subsequent trial comparing DL instruction using a Macintosh-style video laryngoscope (MacVL), with and without video recordings, with conventional DL instruction. METHODS: Medical students with no prior laryngoscopy experience were recruited during their two-week anesthesia rotation. During the first (TRAINING) week, students were randomized into three groups: Control (Macintosh direct laryngoscope), VL-1 (MacVL with real-time feedback), and VL-2 (MacVL with real-time feedback plus video recordings of laryngoscopies)...

PURPOSE: Very elderly (over 80 yr of age) critically ill patients admitted to medical-surgical intensive care units (ICUs) have a high incidence of mortality, prolonged hospital length of stay, and dependent living conditions should they survive. The primary purpose of this study is to describe the outcomes and differences in outcomes between very elderly medical patients and their surgical counterparts admitted to Canadian ICUs, thereby informing decision-making for clinicians and substitute decision-makers...

PURPOSE: Deep brain stimulation (DBS) can be an effective treatment option for patients with essential tremor and Parkinson's disease. This review provides an overview on the functioning of neurostimulators and recent advances in this technology and presents an updated guide on the anesthetic management of patients with an implanted neurostimulator undergoing surgery or medical intervention. SOURCE: A search was conducted on MEDLINE®, EMBASE™, and Cochrane Database of Systematic Reviews databases to identify studies published in English from 1974 to December 2015...
