#1
Johan Bjellvi, Niklas Timby, Roland Flink
Status epilepticus, a condition with prolonged or repeated seizures, is a common neurological emergency with significant morbidity and mortality. This text outlines the treatment and initial work-up for convulsive and non-convulsive status epilepticus in adults and children. The most serious form is convulsive (tonic-clonic) status epilepticus, which requires rapid treatment and work-up. Bensodiazepines are the preferred initial treatment, while antiepileptic drugs and anesthetics are added if seizures continue...

The article is based on the case analysis of a sudden and unexpected intraoperative death of a 51-year-old female patient with hypertrophic cardiomyopathy, who was undergoing a non-cardiac operation in a non-cardiosurgery clinic, from acute precipitation of left ventricular outflow tract obstruction provoked by surgery and anesthesia. It emphasizes the importance of raising non-cardiac anesthesiologists' awareness of the issue and having clear standards of pre-operative evaluation and perioperative management of patients with hypertrophic cardiomyopathy in order to avoid fatal medical errors...

While spinal cord deformation is thought to be a predictor of spinal cord injury severity, few researchers have directly investigated the dynamic cord deformation or distribution of the deformation between white and grey matter of the in vivo spinal cord during impact. This knowledge would help to establish correlations among impact parameters, internal spinal cord deformation, and histological and functional outcomes. Relying on surface deformations alone may not be a sufficient representation of spinal cord deformation...

PURPOSE: Acute hyperglycemia in patients with traumatic brain injury correlates with a poor neurological outcome. We investigated the endothelium function of rat cerebral arterioles during acute hyperglycemia and after reducing the glucose levels using insulin. We also examined whether or not oxidative stress was involved in the cerebral arteriole response to acute hyperglycemia. METHODS: In isoflurane-anesthetized, mechanically ventilated rats, we used closed cranial window preparation to measure the changes in the pial arteriolar diameter following the topical application of acetylcholine (ACh) or adenosine...

BACKGROUND: Eutectic mixtures of lidocaine and prilocaine are used during painful dermatological procedures. Poisoning is rarely reported in adults. MATERIAL AND METHOD: We report three cases of women who experienced lidocaine and prilocaine poisoning after laser-assisted hair removal. Plasma levels of local anesthetics were assayed by a fully validated liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) method. CASE REPORTS: The rules of application of the anesthetic cream were observed apart from the maximum dose and/or maximum surface area...

The pupil undergoes irregular oscillations when exposed to light. These oscillations, known as pupillary unrest in ambient light, originate from oscillatory activity within the Edinger-Westphal nucleus in the midbrain. The midbrain and upper pons also contain nuclei known to be very sensitive to the effects of anesthetics that play a central role in maintaining wakefulness. We hypothesized that anesthetics may display similar effects on wakefulness and pupillary unrest. Repeat measurements of pupillary unrest using infrared pupillometry were performed in 16 patients undergoing general anesthesia and 8 patients undergoing propofol sedation...

BACKGROUND: Melatonin has analgesic, anti-inflammatory, sedative, and anxiolytic properties. However, the relationship between endogenous melatonin levels and postoperative analgesic requirements has not been well elucidated in patients undergoing bariatric surgery. We studied endogenous melatonin levels, cortisol levels, body temperatures, and the relationship between the level of endogenous melatonin and postoperative morphine consumption. METHODS: The trial was conducted among 30 patients who were scheduled for laparoscopic bariatric surgery...

Mazen Asaad, Jin Hyung Lee
Alzheimer's disease is a leading healthcare challenge facing our society today. Functional magnetic resonance imaging (fMRI) of the brain has played an important role in our efforts to understand how Alzheimer's disease alters brain function. Using fMRI in animal models of Alzheimer's disease has the potential to provide us with a more comprehensive understanding of the observations made in human clinical fMRI studies. However, using fMRI in animal models of Alzheimer's disease presents some unique challenges...

PURPOSE: Carpal tunnel release (CTR) is a common surgical procedure, representing a financial burden to the health care system. The purpose of this study was to test whether the choice of CTR technique (open carpal tunnel release [OCTR] vs endoscopic carpal tunnel release [ECTR]), surgical setting (operating room vs procedure room [PR]), and anesthetic type (local, monitored anesthesia care [MAC], Bier block, general) affected costs or payments. METHODS: Consecutive adult patients undergoing isolated unilateral CTR between July 2014, and October 2017, at a single academic medical center were identified...

INTRO: Venous thromboembolism (VTE) is a rare event in children, but can cause significant morbidity and mortality. The majority of research on pediatric VTE has been in the trauma and critical care populations. The incidence of VTE after surgery in children is not well-established. OBJECTIVE: The objective was to evaluate the incidence of VTE in the 30 days after surgery, as well as associated risk factors. STUDY DESIGN: All cases in the National Surgical Quality Improvement Program Pediatric (NSQIPP) database from 2012 to 2015 were assessed for presence of post-operative VTE...

BACKGROUND AND OBJECTIVES: Quadratus lumborum block was first described in 2007 and currently there are descriptions of its achievement through four different injection points. This blockage provides abdominal wall and visceral analgesia, and one of its mechanisms is the dispersion of the local anesthetic into the paravertebral space. We describe the performance of a continuous quadratus lumborum type II block for postoperative analgesia in a partial nephrectomy. CASE REPORT: A 64-year-old woman, scheduled for partial left laparoscopic nephrectomy...

PURPOSE: Preoperative anxiety in children is associated with postoperative distress in recovery. Both are predictors of long-term maladaptive behavior. Remedies have been suggested to modify individual risk factors, but overall strategy is lacking. DESIGN: An approach to anxiety reduction coordinated throughout the hospital experience has been developed in our day-stay pediatric surgical unit. METHODS: There is a preadmission familiarization visit...

Anesthetic protocols may influence adrenal function. Effective methods for modulating stress are desirable to minimize secondary effects during the perioperative period. The aim of this study was to evaluate the effects of the administration of propofol with dexmedetomidine or ketamine on corticoadrenal function and heart and respiratory rates. A random treatment-order design was used: each rabbit received all treatments, with at least 14 d between experiments. Rabbits were assigned to 3 treatment groups (10 per group): group 1, 1 mL normal saline solution intravenously; group 2, propofol (3 mg/kg IV) and dexmedetomidine (0...

The injectable anesthetic mixture ketamine-xylazine is commonly used for electrophysiologic experiments in laboratory animals, especially rodents. General anesthesia can induce significant changes in systemic physiology, including those that compromise neural function, thus introducing research confounds. The extent of such concerns varies by agent. Here in mice, we compared the effects of ketamine-xylazine and urethane-xylazine anesthesia on systemic physiologic parameters and the vestibular sensory evoked potential (VsEP), a tool used commonly to assess peripheral vestibular function...

INTRODUCTION: Enterohepatic circulation (EHC) of conjugated bile acids is an important physiological process crucial for regulation of intracellular concentrations of bile acids and their function as detergents and signal carriers. Only few bile acid-derived imaging agents have been synthesized and hitherto none have been evaluated for studies of EHC. We hypothesized that N-(4-[18 F]fluorobenzyl)cholylglycine ([18 F]FBCGly), a novel fluorine-18 labeled derivative of endogenous cholylglycine, would be a suitable tracer for PET of the EHC of conjugated bile acids, and we report here a radiosynthesis of [18 F]FBCGly and a proof-of-concept study by PET/MR in rats...

The ventral tegmental area (VTA) is the origin of the mesolimbic dopaminergic system known to play an integral role in mediating reward and development of drug addiction. Although the differences in neuronal plasticity of VTA at various ages remain to be understood, age is known to influence the effects of chronic opioids. In addition, adaptations associated with exposure to opioids within glial populations located in the VTA are poorly understood. The objective of the study was to determine if there are changes in astrocytic immunofluorescent labeling in the VTA following chronic morphine administration in a rat model at different ages: newborn at postnatal day (PD)7 and adult (estimated PD57)...

BACKGROUND: A clear imperative exists to optimize the preoperative pain management of hip fracture patients. Increasingly, fascia iliaca compartment blocks (FICBs) are being effectively utilized as an adjunct to oral analgesia in the emergency department. PURPOSE: We investigated the feasibility, safety, and delivery rate when junior doctors and specialist nurses are trained in FICBs delivery, alongside the introduction of a step-by-step proforma. METHODS: We conducted a retrospective study of hip fractures patients presenting preinterventions (n = 138) between October and December 2014 and postinterventions (n = 246) between April and August 2015...

BACKGROUND: Choosing the most effective type of anesthesia for controlling postoperative pain is paramount for improving patient outcomes and patient satisfaction. Most often, the type of anesthesia selected is dependent on the duration and type of surgical procedure and anesthesiologist/surgeon preference. Using a combination of regional anesthesia techniques, however, remains the cornerstone of multimodal analgesia for postoperative pain management after total knee arthroplasty. PURPOSE: The purpose of this study was to determine what regional anesthesia techniques and/or combinations of regional anesthesia techniques provided the best postoperative pain control in patients who had undergone a total knee arthroplasty...
