Alcohol withdrawal syndrome (AWS) is a complex neurologic disorder that develops after an acute reduction in or cessation of chronic alcohol consumption that alters neurotransmitter conduction. The incidence of AWS in the intensive care unit varies, but has been associated with poor outcomes. This is primarily driven by downregulation of gamma-aminobutyric acid (GABA) leading to autonomic excitability and psychomotor agitation. No clinical assessment tools have been validated to assess for AWS in the intensive care unit, particularly for patients requiring mechanical ventilation...

Few studies evaluate anesthesia in black-tailed prairie dogs (Cynomys ludovicianus). Isoflurane inhalant anesthesia is usedin this species most commonly, but injectable protocols are poorly described. Here we compared the physiologic effects, including anesthetic depth, vital signs, and hematologic changes, of anesthetic protocols using isoflurane or a combination ofdexmedetomidine, ketamine, and midazolam in black-tailed prairie dogs. In a randomized, complete crossover study design, intact male black-tailed prairie dogs (n = 9; age, 6 mo) were anesthetized by using a combination of dexmedetomidine (0...

Background and Aims: Shivering after spinal anesthesia is a common complication and can occur in as many as 40%-70% of patients after regional anesthesia. This shivering, apart from its physiological and hemodynamic effects, has been described as even worse than surgical pain. The aim of the study was to evaluate and compare the effectiveness of prophylactic use of intravenous (IV) ketamine, dexmedetomidine, and tramadol for prevention of shivering after spinal anesthesia. Material and Methods: Two hundred American Society of Anesthesiologists physical status I and II patients subjected to spinal anesthesia were included in the study...

This study provides a review of the contemporary literature for the effects of most commonly used anesthetic drugs for sedation and anesthesia during adult electrophysiologic (EP) studies where supraventricular tachycardias (SVT) need to be induced for diagnostic purposes and/or catheter ablation. Some medications may affect cardiac electrophysiology and conduction, altering the ability to induce the arrhythmia, and may have negative impact on mapping and ablation treatment. The objective of the study is to determine the best sedative choice during SVT ablations...

Preemptive analgesia is an intervention provided before initiating painful stimuli that may reduce or prevent subsequent pain. This systematic review examines the evidence supporting the practice of preemptive analgesia in minimally invasive gynecologic surgery (MIGS). We searched PubMed, Cochrane Register for Controlled Trials, and Embase from inception through February 26, 2018. The search was limited to human and English language studies. A total of 324 studies were identified. The abstracts were screened for relevance for minimally invasive gynecologic surgery (MIGS) and preemptive analgesia...

Background: A malfunction or impairment of swallow function can potentiate aspiration events and interfere with both quality of life and survival. Establishing an animal model for swallow research would provide a better understanding of its pathophysiology and would also allow for the development and validation of physiologically based clinical interventions to improve swallow function. Two requirements define the ideal model for longitudinal exploration: 1) identification of species similar to human in form and function; and 2) provision for reliable and reproducible evoked swallow under general anesthesia and one that would also support a longitudinal study design...

PURPOSE OF REVIEW: Electroconvulsive therapy (ECT) is a well established and effective therapy in treatment-resistant depression. It is performed under general anesthesia, but no consensus exists regarding the optimal anesthetic drugs. A growing interest in optimizing adjunctive medication regimes in ECT anesthesia has emerged in recent years. Moreover different methods of seizure induction have been evaluated. RECENT FINDINGS: Pretreatment with dexmedetomidine eased the propofol injection pain and reduced the hyperdynamic response to ECT, but prolonged recovery...

Jie Liu, Yong Wang, Wuhua Ma
INTRODUCTION: Perioperative shivering during cesarean sections (CSs) under neuraxial anesthesia (NA) is clinically common but often under-treated. It may prominently increase oxygen consumption, which can be catastrophic for parturients with ischemic cardiovascular disease. Thus, the prevention and treatment of shivering may be of great significance in parturients. The purpose of this systematic review was to investigate the effectiveness of several drugs on shivering prevention and treatment during CSs under NA...
