In this report, we describe the case of a premature infant (36 weeks' postgestational age) who underwent left inguinal hernia repair under general anesthesia without the use of any airway device. Anesthesia was induced and maintained with sevoflurane in oxygen and nitrous oxide. An ultrasound-guided transversus abdominis plane block was performed that provided effective analgesia, obviating the need for opioids in the intraoperative period. The infant's hemodynamics remained stable throughout the surgery. This report also briefly explains the advantages of using a transversus abdominis plane block, compared with neuraxial blockade, for hernia repair surgery...

Congenital heart defects are associated with various physiological disturbances. They pose anesthetic challenges for both cardiac and noncardiac surgeries. Atrioventricular septal defects are due to a developmental failure in the separation of atria and the ventricles into separate chambers and failure in the separation of mitral and tricuspid valves. We present a case of a child (1½ years), weighing 10 kg, diagnosed as congenital hydrocephalus who was planned for ventriculoperitoneal shunt. Child was having an oxygen saturation of 76% on room air...

OBJECTIVE: Our asphyxia cardiac arrest (ACA) rat model is well established. The original model was designed in the 1990(th) using halothane and nitrous oxide for pre-insult anesthesia. Because of its hepato-toxicity and its potential to induce severe liver failures, halothane is no longer used in clinical anesthesia for several years. In order to minimize the health risk for our laboratory staff as well as to keep the experimental settings of our model on a clinically oriented basis we decided to replace halothane by sevoflurane...

PURPOSE: Methotrexate administration is associated with frequent adverse neurological events during treatment for childhood acute lymphoblastic leukemia. Here, we present evidence to support the role of common drug interactions and low vitamin B12 levels in potentiating methotrexate neurotoxicity. METHODS: We review the published evidence and highlight key potential drug interactions as well as present clinical evidence of severe methotrexate neurotoxicity in conjunction with nitrous oxide anesthesia and measurements of vitamin B12 levels among pediatric leukemia patients during therapy...

Although several adjuncts to the general anesthetic propofol have been proposed, there is insufficient research identifying the ideal agent, and in what dosage, to combine with propofol in dental outpatient anesthesia. Here we examined the combination of remifentanil or nitrous oxide and propofol in patients with severe dental avoidance undergoing dental treatment in the outpatient setting. Eighty patients were randomized to 4 groups and administered propofol/saline solution (PS; n = 20), propofol/remifentanil 0...

BACKGROUND: Neurodevelopmental disorders are increasing in prevalence worldwide. Previous work suggests that exposure to the environmental air pollutant and greenhouse gas - nitrous oxide (N2O) - may be an etiological factor in neurodevelopmental disorders through the targeting of several neural correlates. METHODOLOGY: While a number of recent systematic reviews have addressed the role of general anesthesia in the surgical setting and neurodevelopmental outcomes, a narrative mini-review was conducted to first define and characterize the relevant variables (i...

Scavenging systems and administrative and work practice controls for minimizing occupational exposure to waste anesthetic gases have been recommended for many years. Anesthetic gases and vapors that are released or leak out during medical procedures are considered waste anesthetic gases. To better understand the extent recommended practices are used, the NIOSH Health and Safety Practices Survey of Healthcare Workers was conducted in 2011 among members of professional practice organizations representing anesthesia care providers including physician anesthesiologists, nurse anesthetists, and anesthesiologist assistants...

REVIEW
Christakis Constantinides, Kathy Murphy
To-this-date, the exact molecular, cellular, and integrative physiological mechanisms of anesthesia remain largely unknown. Published evidence indicates that anesthetic effects are multifocal and occur in a time-dependent and coordinated manner, mediated via central, local, and peripheral pathways. Their effects can be modulated by a range of variables, and their elicited end-effect on the integrative physiological response is highly variable. This review summarizes the major cellular and molecular sites of anesthetic action with a focus on the paradigm of isoflurane (ISO) - the most commonly used anesthetic nowadays - and its use in prolonged in vivo rodent studies using imaging modalities, such as magnetic resonance imaging (MRI)...

BACKGROUND: Nonopioid adjuvant medications are increasingly included among perioperative Enhanced Recovery After Surgery protocols. Preoperative pregabalin has been shown to improve postoperative pain and limit reliance on opioid analgesia. Our group investigated the ability of preoperative pregabalin to also prevent postoperative nausea and vomiting (PONV). METHODS: Our group performed a meta-analysis of randomized trials that report outcomes on the effect of preoperative pregabalin on PONV endpoints in patients undergoing general anesthesia...

Adaptations in maternal carbohydrate metabolism are particularly important in pregnancy because glucose is the principal energy substrate used by the fetus. As metabolic homeostasis is intricately linked to the circadian system via the rhythmic expression of clock genes, it is likely that metabolic adaptations during pregnancy also involve shifts in maternal circadian function. We hypothesized that maternal adaptation in pregnancy involves changes in the hepatic expression of clock genes, which drive downstream shifts in circadian expression of glucoregulatory genes...

BACKGROUND: Thyroid-stimulating hormone (TSH)-secreting pituitary adenomas are a rare cause of secondary hyperthyroidism. Anesthetic management of these patients has not been formally described in the literature. MATERIALS AND METHODS: Patients who underwent resection of a TSH-secreting pituitary adenoma during 1987 to 2012 at a single institution were identified. Preoperative thyroid hormone state, anesthetic management, and outcome were recorded. Hemodynamic associations with intraoperative events were compared between those who were hyperthyroid and euthyroid at the time of surgery...

INTRODUCTION: Most children are casual and moderately agreeable in the dental treatment environment, however some of them show practices that upset the professional and make the protected conveyance of worthy treatment extremely troublesome. For such cases dental practitioner utilizes behavior management techniques. At the point when behavioral administration procedures come up short, some type of pharmacologic sedation or anesthesia may be an important and vital option. Dental sedation is a strategy in which the utilization of a medication or drugs produce(s) a condition of depression of the central sensory system empowering treatment to be completed during which verbal contact with the patient is kept up all through the time of sedation...

For patients with HPS who require anesthesia for a procedure, HPV should be maintained to prevent worsening hypoxemia. Here, the case of a 9-yr-old girl who was scheduled for a living donor liver transplantation is presented. The patient suffered from end-stage liver disease with HPS due to biliary atresia, which contributed to the development of a diffuse pulmonary AVF. Consequently, anesthetic management of this patient involved two different types of pulmonary shunt. It is important to maintain HPV, not only to prevent worsening of the hypoxia caused by HPS but also to inhibit an increase in PVR that could cause an increase of shunt flow through the pathological fistula...

OBJECTIVE: It has been demonstrated that anesthetics exposure may lead to neurocognitive impairment in developing brain of animal models. However, for the limitation that the animal models cannot fully mimic the dose and duration in clinical settings especially for dental general anesthesia, the clinical significance of anesthetics exposure on developing central nervous system remains undetermined. Therefore, we conducted the current study in order to observe the fluctuation of intelligence quotient (IQ) after the administration of dental general anesthesia comparing to that before surgery...

BACKGROUND: Recent concerns regarding possible long-term effects of early anesthesia exposure on neurodevelopment in children have provided an impetus to explore alternative anesthetic techniques using potentially neuroprotective agents. Dexmedetomidine has not been implicated in anesthesia-induced neurotoxicity and has been shown to be neuroprotective in preclinical studies. We describe a case series of 50 neonates and infants who received dexmedetomidine sedation with caudal anesthesia instead of general endotracheal anesthesia for inguinal hernia surgery...

BACKGROUND: Early postnatal exposure to general anesthesia (GA) may be detrimental to brain development, resulting in long-term cognitive impairments. Older literature suggests that in utero exposure of rodents to GA causes cognitive impairments in the first-generation as well as in the second-generation offspring never exposed to GA. Thus, the authors hypothesize that transient exposure to GA during critical stages of synaptogenesis causes epigenetic changes in chromatin with deleterious effects on transcription of target genes crucial for proper synapse formation and cognitive development...
