BACKGROUND AND AIM: Recent studies have advised narcotic less anaestheic techniques for breast cancer surgeries due to altered immune system by use of opioids. So we planned this study to compare the efficacy of dexmedtomidine with fentanyl in breast cancer surgery in terms of haemodynamic stability, anaesthetic sparing effects, recovery profile and postoperative analgesia. MATERIAL AND METHODS: In this randomized prospective controlled trial, a total of 60 female patients were randomly assigned into two groups...

BACKGROUND Cardiac arrhythmia is a significant cause of morbidity and mortality. In this study, through examination of the effects on the QTc interval of different doses of hyperbaric bupivacaine, we investigated the relationship with arrhythmia. MATERIAL AND METHODS A total of 60 patients were separated into 2 groups: spinal block was applied with 10 mg bupivacaine to Group S1 and with 15 mg to Group S2. The mean arterial pressure (MAP) and heart rate (HR) values were recorded before the spinal block and at 5 and 30 min after the block and at 60 min postoperatively...

SESSION TITLE: Cardiovascular CasesSESSION TYPE: Case ReportsPRESENTED ON: Saturday, March 22, 2014 at 04:15 PM - 05:15 PMINTRODUCTION: Central venous catheters (CVC) are placed in large caliber veins, and though relatively safe, complications can occur. When chest radiograph cannot verify proper CVC placement, further assessments are mandated. We present a case of questionable placement of a left-sided CVC. CASE PRESENTATION: 59 y/o female was admitted for increasing dyspnea and atrial flutter...

AUTHORS: Douglas B. Craig, W.M. Wahba, Hillary Don CITATION: Can Anaesth Soc J 1971; 18: 92-9. PURPOSE: Surgery and anesthesia expose patients to moderate and sometimes extreme positioning changes that are often unphysiological. The purpose of this article is to highlight and contextualize a seminal study from the Journal archives that explores the effect of several commonly utilized surgical positions (supine, Trendelenburg and lithotomy) and age on basic lung volumes as well as the volume at which small airway closure (AC) (also known as closing volume [CV]) occurs...

PURPOSE: To review the history of the early development of cyclopropane PRINCIPAL FINDINGS: Cyclopropane was initially investigated because it was thought to be the toxic element in ethylene. Instead, it turned out to be an excellent anesthetic with very rapid onset and recovery while maintaining stable hemodynamics. Its use was ultimately limited because it was highly explosive. Development required collaboration among laboratory scientists and clinicians in Toronto, Canada, clinicians in Madison, USA, and industry in both countries...

PURPOSE: In 1978, Drs. R Knill and A. Gelb published the results of a study to measure the effect of subanesthetic levels of halothane on the ability of fit volunteers to respond to sustained hypoxia, and to determine how long potentially hazardous levels of halothane persist after a brief non-complex surgical procedure in healthy patients. The purpose of this commentary is to highlight the historical context of their findings and the impact of their work on our modern day practice of anesthesia...

PURPOSE: This retrospective observational study was performed to determine if the age of transfused units of red blood cells (RBCs) was related to mortality. The study included 31 transfused patients admitted to the intensive care unit during 1992 with severe sepsis (i.e., sepsis associated with organ dysfunction, hypoperfusion, or hypotension). PRINCIPAL FINDINGS: Nineteen of 31 patients (61%) died. On average, non-survivors received older RBC units than survivors...

UNLABELLED: Hypoxic pulmonary vasoconstriction (HPV) is a fundamental physiological process whereby ventilation/perfusion matching is optimized through the constriction of the pulmonary circulation supplying poorly ventilated lung units. In their 1981 paper in the Journal, Noble, Kay, and Fisher used a series of animal experiments to show that alveolar carbon dioxide (CO2) plays a critical role in the regulation of hypoxic pulmonary vasoconstriction. At physiological concentrations, CO2 potentiates the HPV response, and the absence of alveolar CO2 blunts HPV...

UNLABELLED: This study was undertaken to determine the contribution of postoperative pain to the known changes that occur to respiratory function in the postoperative period. The authors studied changes in functional residual capacity (FRC) and vital capacity (VC) either in the postanesthesia care unit or on postoperative day one in eight relatively healthy adult patients having upper abdominal surgery. These values were compared with measurements immediately before surgery. Variables were measured postoperatively during pain and then again after establishment of epidural analgesia...

UNLABELLED: Francis G. Ruston MD CITATION: Ruston FG. Epidural anaesthesia in infants and children. Can Anaesth Soc J 1954: 1: 37-44. PURPOSE: The author describes the use of single-shot epidural anesthesia in a series of 44 infants and children. The patients were anesthetized in hospitals in Hamilton, Ontario from 1949 until the time of publication in 1954. The study aimed to describe the indications and efficacy of this technique as well as any apparent complications...

PURPOSE: Determining epidural catheter placement and accurately depositing corticosteroids at the site of the pathology in adults with chronic back pain can be challenging. Fluoroscopy is considered the standard of care for guiding epidural catheter positioning and subsequent injection in patients receiving epidural corticosteroids, but the technique has some limitations. We hypothesized that electrophysiological stimulation using the Tsui test is feasible for determining the appropriate epidural catheter position in adults with chronic back pain receiving epidural corticosteroids...

INTRODUCTION: Selective Dorsal Rhizotomy (SDR) is the only surgical intervention with class I evidence supporting permanent reduction in spasticity for children with cerebral palsy (Paediatr Anaesth, 12, 2002, 296; Neurosurg Focus, 21, 2006, e2). Postoperatively, adequate analgesia can be difficult to achieve (J Neurosurg, 105, 2006, 8; Childs Nerv Syst, 17, 2001, 556; Pediatr Neurosurg, 43, 2007, 107; Anesth Analg, 79, 1994, 340; Reg Anesth Pain Med, 24, 1999, 438; Pediatr Anesth, 19, 2009, 1213)...

BACKGROUND: Intraoperative arterial hypotension can lead to severe complications in patients undergoing carotid endarterectomy, in particular if cerebral auto-regulation is impaired. Short-acting agents, such as phenylephrine or ephedrine, commonly used to correct intra-operative hypotension, have different hemodynamic effects. Recently, it was reported that, in healthy anesthetized subjects with intact cerebral auto-regulation, frontal lobe cerebral tissue oxygenation declined after phenylephrine bolus administration, while it was preserved after ephedrine use (Br J Anaesth 107:209-217, 2011; Neurocrit Care 12:17-23, 2010)...

Further to the Expression of Concern posted online on March 13th, 2012, it is with considerable regret that the Canadian Journal of Anesthesia hereby retracts the above-cited article by Dr. Yoshitaka Fujii as a result of:(1) overwhelming evidence of fabrication relating to the fact that the distributions of many variables reported by Dr. Fujii in these studies are exceedingly unlikely; and the inability of Dr. Fujii’s institution to attest to the integrity of the study and/or the data conducted under its auspices, as set out in the Joint Editors-in-Chief Request for Determination of April 9, 2012...
