Intraoperative lidocaine infusion has become widely accepted as an adjunct to general anesthesia where its use has been associated with opioid-sparing and enhanced recovery. The aims of this study were to determine whether or not intravenous (IV) lidocaine infusion (a) has an anesthetic sparing effect during major colorectal procedures and (b) if it also affects level of hypnosis as measured by bispectral index (BIS). Twenty-five patients undergoing laparotomy for resection of colorectal tumours were randomized to receive either IV lidocaine (1...

BACKGROUND: Obstructive sleep apnea (OSA) is a prevalent condition that is associated with early postoperative respiratory complications (PRCs). As the majority of patients with OSA are undiagnosed, preoperative screening remains the most efficient method to identify suspected OSA. METHODS: This retrospective study was performed on patients undergoing anesthesia in a single academic medical center. We assigned OSA risk class retrospectively to all patients in the study by using the Perioperative Sleep Apnea Prediction (PSAP) score...

In severe cases of status asthmaticus, when conventional therapies fail, volatile anesthetic agents remain a therapeutic option. When delivered outside of the operating room setting, specialized delivery techniques are needed to ensure the safe and effective use of volatile anesthetic agents. We present a 16-year-old adolescent with status asthmaticus who required the therapeutic administration of the volatile anesthetic agent, sevoflurane, in the pediatric intensive care unit (PICU). Although initially effective in reducing bronchospasm, progressive hypercarbia developed due to defective functioning of the carbon dioxide absorber of the anesthesia machine...

Novel (non-fluoroquinolone) inhibitors of bacterial type II topoisomerases (NBTIs) are an emerging class of antibacterial agents. We report an optimized series of cyclobutylaryl-substituted NBTIs. Compound 14 demonstrated excellent activity both in vitro (S. aureus MIC90=0.125μg/mL) and in vivo (systemic and tissue infections). Enhanced inhibition of Topoisomerase IV correlated with improved activity in S. aureus strains with mutations conferring resistance to NBTIs. Compound 14 also displayed an improved hERG IC50 of 85...

BACKGROUND: Periarticular injections have become a valuable adjunct to multimodal pain control regimens after knee and hip arthroplasties. Injection techniques vary greatly among surgeons with little standardization of practice. METHODS: We performed an extensive literature search to determine where nociceptive pain fibers are located in the hip and the knee and also to explore the pharmacology of periarticular cocktail ingredients. RESULTS: Large concentrations of nociceptors are present throughout the various tissues of the knee joint with elevated concentrations in the infrapatellar fat pad, fibrous capsule, ligament insertions, periosteum, subchondral bone, and lateral retinaculum...

Split-thickness skin grafting (STSG) is the most common reconstructive procedure in managing burn injuries. Harvesting split-thickness skin creates a new partial thickness wound referred to as the donor site. Pain at the donor site is reported to be one of the most distressing symptoms during the early post-operative period. Here, we a) identify strategies for managing donor site pain, b) assess the quality of individual studies and c) formulate evidence-based recommendations based on the amount and consistency of evidence...

The potential for commonly used anesthetics and sedatives to cause neuroapoptosis and other neurodegenerative changes in the developing mammalian brain has become evident in animal studies over the past 15 years. This concern has led to a number of retrospective studies in human infants and young children, and some of these studies observed an association between exposure to general anesthesia as an infant, and later neurobehavioral problems in childhood. This association is particularly evident for prolonged or repeated exposures...

OBJECTIVE: N-butane and n-pentane can both produce general anesthesia. Both compounds potentiate γ-aminobutyric acid type A (GABAA) receptor function, but only butane inhibits N-methyl-d-aspartate (NMDA) receptors. It was hypothesized that butane and pentane would exhibit anesthetic synergy due to their different actions on ligand-gated ion channels. STUDY DESIGN: Prospective experimental study. ANIMALS: A total of four Xenopus laevis frogs and 43 Sprague-Dawley rats...

Malignant hyperthermia (MH) may lead to metabolic crisis of skeletal muscle in susceptible individuals following exposure to triggering agents such as volatile anesthetics or depolarizing muscle relaxants. MH is a rare and a potentially lethal disease, which can lead to cardiac arrest. We report a case of severe MH, in which the rapidly evolving signs of hypermetabolism eventually resulted in cardiac arrest. Despite conventional treatments following cardiopulmonary resuscitation, the patient's vital signs did not improve...

Diabetes mellitus (DM) is characterized by alteration in carbohydrate metabolism, leading to hyperglycemia and increased perioperative morbidity and mortality. It evolves with diverse and progressive physiological changes, and the anesthetic management requires attention regarding this pathology interference in multiple organ systems and their respective complications. Patient's history, physical examination, and complementary exams are important in the preoperative management, particularly glycosylated hemoglobin (HbA1c), which has a strong predictive value for complications associated with diabetes...

Propofol (2,6-diisopropylphenol) is probably the most widely used intravenous anesthetic agent in daily practice. It has been reported to show immunomodulatory activity. However, the effect of propofol on the differention of T cells remains unclear. In this study, we demonstrated for the first time that propofol inhibited both interleukin (IL)-6 plus transforming growth factor-β (TGF-β)-induced Th17 cell differentiation in vitro and in LPS-challenged mice. Propofol also suppressed the IL-6-induced phosphorylation of Janus kinase-2 (JAK2)/signal transducer and activator of transcription (STAT3) pathway, a cytokine-activated essential transcription factor in Th17 cell development, which occurred concomitantly with the enhancement of suppressor of cytokine signaling-3 (SOCS3) expression involved in the downregulation of STAT3 phosphorylation...
