BACKGROUND: Intra-abdominal hypertension jeopardizes abdominal organ perfusion and venous return. Contemporary recognition of elevated intra-abdominal pressure (IAP) plays a crucial role in reducing mortality and morbidity. We evaluated ultrasound guided tonometry in this context hypothesizing that the vertical chamber diameter of this device inversely correlates with intra-abdominal pressure. METHODS: IAP was increased in six 5 mmHg steps to 40 mmHg by instillation of normal saline into the peritoneal cavity of eight anesthetized pigs...

An 11-year-old male child with fractures in both bones in his left forearm presented for open reduction and internal fixation. The pre-anesthetic check-up and investigations did not reveal any pre-existing underlying cardio-respiratory disease. The patient had an uneventful peri-operative period during the operation and was comfortable without any anxiety or restlessness. After an uneventful induction and intubation as per routine protocol, the patient received 600 mg of amoxicillin+clavunate intravenously as an antibiotic...

OBJECTIVES: Lumbar punctures (LPs) are commonly performed in febrile infants to evaluate for meningitis, and local anesthesia increases the likelihood of LP success. Traditional methods of local anesthesia require injection which may be painful or topical application which is not effective immediately. Recent advances in needle-free jet injection may offer a rapid alternative to these modalities. We compared a needle-free jet-injection system (J-Tip(™) ) with 1% buffered lidocaine to topical anesthetic (TA) cream for local anesthesia in infant LPs...

BACKGROUND: Lumbar radicular pain often results from lumbar disc herniation, spinal stenosis, or degenerative spondylolisthesis. Minimally invasive disc decompression procedures, such as nucleo-annuloplasty or epiduroscopic neural decompression by laser, have been devised to treat such pain. OBJECTIVE: The short-term outcomes of disc decompression by endoscopic epidural laser decompression (EELD) or transforaminal epiduroscopic laser annuloplasty (TELA) were compared in patients with lumbar radicular pain due to disc herniation...

The aim of this review is to analyze what's new on anesthetic prospective to perioperative management for thyroid surgery. For recent decades intraoperative neuromonitoring (IONM) during thyroid and parathyroid surgery has obtained more and more popularity. New modality of anesthetic technique was also developed to incorporate into surgical teamwork. For example, the precise position of EMG tube and optimal use of neuromuscular blocking agents (NMBAs) play key roles in successful IONM system. Special focus is paid to following issues: (I) preoperative airway evaluation and pre-op preparation; (II) anesthetic managements including advanced intubation tools, NMBAs and sugammadex; and (III) post-op adverse events such as pain and postoperative nausea vomiting...

To investigate the effects of a xylazine infusion during isoflurane anesthesia on global perfusion parameters and gastrointestinal oxygenation and microperfusion, 8 adult warmblood horses were sedated with xylazine and anesthesia induced with midazolam and ketamine. Horses were mechanically ventilated during anesthesia. After 3 h of stable isoflurane anesthesia (FEIso 1.3 Vol %), a xylazine infusion with 1 mg/kg body weight (BW) per hour was started for 1 h and then stopped. Before, during, and after xylazine infusion, heart rate (HR), arterial blood pressure (MAP), cardiac output (CO), central venous pressure (CVP), and pulmonary artery pressure (PAP) were measured and systemic vascular resistance (SVR) was calculated...

INTRODUCTION: Optimal teaching and assessment methods and models for emergency airway, breathing, and hemorrhage interventions are not currently known. The University of Minnesota Combat Casualty Training consortium (UMN CCTC) was formed to explore the strengths and weaknesses of synthetic training models (STMs) versus live tissue (LT) models. In this study, we compare the effectiveness of best in class STMs versus an anesthetized caprine (goat) model for training and assessing seven procedures: junctional hemorrhage control, tourniquet (TQ) placement, chest seal, needle thoracostomy (NCD), nasopharyngeal airway (NPA), tube thoracostomy, and cricothyrotomy (Cric)...

OBJECTIVE: The effect of remifentanil on stress response to surgery is unclear. However, there are not clinical studies investigating the relationship between blood remifentanil concentrations and stress hormones. Therefore, the aim of the present study was to assess the association between blood remifentanil concentrations measured after pneumoperitoneum and cortisol (CORT) or prolactin (PRL) ratio (intraoperative/preoperative value), in patients undergoing laparoscopic cholecystectomy...

Concerns regarding reliability and safety, as well as uncertainties about what constitutes adequate performance evaluation, have impeded the clinical translation of PCLC devices. We describe an attempt to address these challenges through design, implementation, and evaluation of a PCLC device for delivering medically-induced coma, with the intention to eventually conduct a clinical trial. This device works by automatically adjusting the infusion rate of propofol - a general anesthetic - in response to an electroencephalogram (EEG) pattern called burst suppression...

The use of pain control for disbudding and dehorning is important from both an animal and industry perspective. Best practices include the use of local anesthetic, commonly given as a cornual nerve block (CNB), and a nonsteroidal anti-inflammatory drug. The proportion is decreasing, but many dairy producers do not use local anesthesia, perhaps in part due to lack of knowledge of the CNB technique. Although this skill is typically learned in person from a veterinarian, alternative methods may be useful. The objective of this trial was to determine if there were differences in the efficacy of online training (n = 23), hands-on training (n = 20), and a combined approach (n = 23) for teaching producers to successfully administer a CNB and disbud a calf...

BACKGROUND: Idiopathic adhesive capsulitis is a condition of uncertain etiology characterized by pain and decreased shoulder range of motion (ROM) that occurs without a known intrinsic disorder. Many treatments have been advocated, yet the best option remains unclear. The purpose of this study was to determine if arthrographic injection of the shoulder joint with steroid and local anesthetic results in decreased pain and increased shoulder function in a cohort of patients with idiopathic adhesive capsulitis...

BACKGROUND: One of the main challenges in anesthesiology is difficult intubation. There are many anatomical parameters for evaluating the feasibility of tracheal intubation; one that can reliably predict a difficult intubation is the Cormack-Lehane classification obtained during direct laryngoscopy. This is an invasive procedure that cannot be performed in an awake patient or for pre-anesthetic airway assessments in patients with no prior history of tracheal intubation. Recently, ultrasound has been successfully used for several airway-related applications...

Anesthesia simulations have been used in pre-clinical medical training for decades to help learners gain confidence and expertise in an operating room environment without danger to a live patient. The authors describe a veterinary anesthesia simulation environment (VASE) with anesthesia scenarios developed to provide a re-creation of a veterinarian's task environment while performing anesthesia. The VASE uses advanced computer technology with simulator inputs provided from standard monitoring equipment in common use during veterinary anesthesia and a commercial canine training mannequin that allows intubation, ventilation, and venous access...

A 47-year-old woman was referred for surgical treatment of osteomyelitis of the mandible. She had already undergone three previous surgeries. Pre-anesthetic airway evaluation predicted a difficult airway, due to the thin, retro-positioned mandible, tongue, and atrophic changes in the lips and soft tissue. We inserted packing gauzes in the buccal mucosa for easier mask fitting and ventilation. During direct laryngoscopic intubation with a nasotracheal tube (NTT), fracture of a thin mandible can easily occur...

Purpose  Currently no guidelines exist for the timing of the injection of anesthetics in surgeries performed under general anesthesia to minimize postoperative pain. To better understand the role of timing of the injection of local anesthesia in hand surgery performed under general anesthesia, we evaluated the effect of pre- versus postincisional local analgesic injection on immediate postoperative pain experience. We hypothesize that the preincisional (preemptive) injection will result in decreased immediate postoperative pain experience and analgesic use when compared with postincisional injection...

AIM OF THE STUDY: As most cardiopulmonary resuscitation (CPR) efforts last longer than 15min, the aim of this study was to compare brain blood flow between the Head Up (HUP) and supine (SUP) body positions during a prolonged CPR effort of 15min, using active compression-decompression (ACD) CPR and impedance threshold device (ITD) in a swine model of cardiac arrest. METHODS: Ventricular fibrillation (VF) was induced in anesthetized pigs. After 8min of untreated VF followed by 2min of ACD-CPR+ITD in the SUP position, pigs were randomized to 18min of continuous ACD-CPR+ITD in either a 30° HUP or SUP position...

OBJECTIVE: Propofol is a new anesthetic agent in clinical practice, but randomized double-blinded prospective studies on its role in pediatric anesthesia remain limited. We aimed to compare the preventive effects of pre-injected lidocaine or ketamine and its pre-mixture on the anesthesia-induced injection pain of propofol using a randomized double-blinded prospective method, and to compare the outcomes with those of medium-/long-chain propofol (M/LCT). METHODS: A total of 360 pediatric patients (aged 5-12 years old) who received elective surgery were randomly divided into six groups (n= 60) as follows...
