Heart rate (HR) and heart rate variability (HRV) in newborns is influenced by genetic determinants, gestational and postnatal age, and other variables. Premature infants have a reduced HRV. In neonatal HRV evaluated by spectral analysis, a dominant activity can be found in low frequency (LF) band (combined parasympathetic and sympathetic component). During the first postnatal days the activity in the high frequency (HF) band (parasympathetic component) rises, together with an increase in LF band and total HRV...

Traumatic injuries to the heart contribute significantly to trauma are associated with high mortality. Cardiac gunshot wounds (GSW) are considered more lethal compared to other injuries and present several unique challenges to the anesthesia management and perioperative care. We are reporting a rare case of a trauma victim who survived a GSW to the heart. We will discuss the perioperative care of penetrating cardiac injuries, the role of the anesthesia team in resuscitation, safe anesthesia induction, cardiopulmonary bypass management, and the essential role of intraoperative transesophageal echocardiogram imaging...

INTRODUCTION: Anesthetists come in contact with more than two-third of hospital patients. Timely referral to anesthetists is vital in perioperative and remote site settings. Delayed referrals, improper referrals, and referrals at inappropriate levels can result in inadequate preparation, perioperative complications, and poor outcome. METHODS: The self administered paper survey to delegates attending anesthesia conferences. Questions were asked on how high-risk, emergency surgical cases remote site and critical care patients were referred to anesthetists and presence of rapid response teams...

Malignant hyperthermia (MH) is a rare but potentially life-threatening disorder encountered during general anesthesia. The use of cardiopulmonary bypass during cardiac surgery can obscure many of the cardinal signs and symptoms of MH. The development of postoperative MH following cardiac surgery is rare, but anesthesiologists and intensivists must maintain a high index of suspicion in order to make a prompt diagnosis. Initiation and tailored maintenance of MH therapy must also consider the complex physiologic changes of patients in the immediate post-cardiac surgery period...

Pediatric cardiac anesthesiology has evolved as a subspecialty of both pediatric and cardiac anesthesiology and is devoted to caring for individuals with congenital heart disease ranging in age from neonates to adults. Training in pediatric cardiac anesthesia is a second-year fellowship with variability in both training duration and content and is not accredited by the Accreditation Council on Graduate Medical Education. Consequently, in this article and based on the Accreditation Council on Graduate Medical Education Milestones Model, an expert panel of the Congenital Cardiac Anesthesia Society, a section of the Society of Pediatric Anesthesiology, defines 18 milestones as competency-based developmental outcomes for training in the pediatric cardiac anesthesia fellowship...

BACKGROUND: In spite of significant improvements in surgical and anesthetic techniques, acute stress response to surgery remains a main cause of mortality and morbidity in coronary artery bypass graft (CABG) surgery patients. Therefore, doing research to find safe and effective modalities with more cardio protective properties seems necessary. OBJECTIVES: In this study, we sought to determine whether intravenous injection of 600 μg Selenium (Se) prior to surgery would limit stress response measured by blood sugar...

BACKGROUND: In patients with ventricular tachycardia/fibrillation (VT/VF) electrical storm (ES) undergoing catheter ablation (CA), hypotension due to refractory VT/VF, use of anesthesia and cardiac stunning due to repeated ICD shocks might precipitate acute hemodynamic decompensation (AHD). OBJECTIVE: We evaluated the outcomes of emergent cardiopulmonary support with extracorporeal membrane oxygenation (ECMO) to rescue AHD in patients undergoing CA of ES. METHODS: Between 2010 and 2016, 21 patients with ES (VT in 11 and PVC-triggered VF in 10) were referred for CA and had periprocedural AHD requiring emergent ECMO support...

INTRODUCTION: We sought to determine whether intrabronchial oxygenation would provide adequate gas exchange during both anesthesia induced apneic and cardiopulmonary arrest and cardiac massage (CPR). METHODS: Ten pigs underwent general anesthesia with mechanical ventilation. Blood gases were measured in each animal at 4 min intervals for up to 28 min. An intrabronchial catheter (4 L/min O2) was inserted through an endotracheal tube after respirator cessation. Group A animals (6) were resuscitated with the catheter but without CPR...

REVIEW
Yalim Dikmen, Aybike Onur
Oxygen is an element, which is used liberally during several medical procedures. The use of oxygen during perioperative care is a controversial issue. Anesthesiologists use oxygen to prevent hypoxemia during surgical procedures, but the effects of its liberal use can be harmful. Another argument for using high oxygen concentrations is to prevent surgical site infections by increasing oxygen levels at the incision site. Although inconclusive, literature concerning the use of high oxygen concentrations during anesthesia show that this approach may cause hemodynamic changes, altered microcirculation and increased oxidative stress...

BACKGROUND: The mechanisms of atrial fibrillation (AF) induced by obstructive sleep apnea (OSA) are not completely understood. This study investigated the roles of the intrinsic and extrinsic cardiac autonomic nervous system in OSA-induced AF and provided noninvasive autonomic nervous modulation for the suppression of OSA-induced AF by using low-level transcutaneous electrical stimulation (LL-TS) of the auricular branch of the vagus nerve at the tragus. METHODS AND RESULTS: Eighteen dogs received tracheostomy under general anesthesia and were randomly divided into 3 groups: the OSA group (OSA was simulated via clamping of the endotracheal tube at end expiration for 1...

INTRODUCTION: Stroke is a devastating complication that is difficult to diagnose in the perioperative setting because of the effects of anesthetic and analgesic agents. Lingering anesthesia effects hinder clinicians in identifying stroke symptoms, frequently resulting in a delay in diagnosis and treatment and in unfavorable outcomes. EVIDENCE ACQUISITION: The authors performed a systematic search in PubMed and the Cochrane Central Register. The search aimed to identify studies published between January 1990 and December 2015 related to the common etiologic factors, incidence, risk factors, risk modifiers, and early management of perioperative stroke...

BACKGROUND: Among patients undergoing non-cardiac surgery, major vascular surgery is associated with a high risk of perioperative myocardial infarction (MI). Currently there are no perioperative MI risk calculators accounting for intraoperative and postoperative risk factors in vascular surgery patients. We aimed to investigate specific risk factors for perioperative MI after major open vascular surgery to determine which patients are at highest risk of MI, and the association of perioperative MI with perioperative transfusion...
