INTRODUCTION: For any surgery in the upper extremity that does not involve the shoulder, a supraclavicular block is preferred, as it is a safe procedure associated with rapid onset and reliable anaesthesia. Although ropivacaine has been extensively studied for epidural anaesthesia, very few reports exist on its use in supraclavicular brachial plexus block. AIM: This study was conducted to investigate and compare the effectiveness of supraclavicular brachial plexus anaesthesia with two different concentrations of ropivacaine (0...

This study evaluated the incidence of nerve puncture and intraneural injection based on the needle approach to the nerve (direct vs. tangential). Two expert operators in regional anaesthesia performed in-plane ultrasound-guided nerve blocks (n = 158) at different levels of the brachial plexus in cadavers, aiming either directly for the nerve (n = 77) or tangentially inferior to the nerve (n = 81). After reaching the outer limit of the nerve, the needle was intentionally advanced approximately 1 mm in both approaches, and 0...

Midbrain dopaminergic neurons are implicated in the control of motor functions and reward-driven behaviours. The function of this neuronal population is strongly connected with distinct patterns of firing - irregular or bursting, which either maintains basal levels of dopamine or leads to phasic release, respectively. Heterogeneity of dopaminergic neurons, observed on both structural and functional levels, is also reflected in different responses of DA neurons to changes in global brain states. Preparation of urethane anaesthetised animal is a broadly used model to study brain state dependent activity of neurons...

OBJECTIVES: Transversus abdominis plane block is a regional anaesthesia technique that has proven to be effective for postoperative pain reduction in different abdominal surgical procedures. This study evaluated its efficacy on post laparoscopic hysterectomy pain intensity and analgesic consumption. MATERIALS AND METHODS: Randomized controlled trial which included 40 patients scheduled for laparoscopic hysterectomy, enrolled in 2 groups: transversus abdominis plane block+systemic analgesia (Group 1; n=20), versus systemic analgesia (Group 2; n=20)...

Studies in mice using resting-state functional magnetic resonance imaging (rs-fMRI) have provided opportunities to investigate the effects of pharmacological manipulations on brain function and map the phenotypes of mouse models of human brain disorders. Mouse rs-fMRI is typically performed under anaesthesia, which induces both regional suppression of brain activity and disruption of large-scale neural networks. Previous comparative studies using rodents investigating various drug effects on long-distance functional connectivity (FC) have reported agent-specific FC patterns, however, effects of regional suppression are sparsely explored...

Pregnancies complicated by congenital or acquired heart diseases are at high risk of maternal, obstetrical and neonatal poor outcomes. During the period 2000-2014, 197 pregnancies occurring in 147 women with heart disease were managed in our institution. A maternal cardiac event complicated 13 pregnancies. Obstetrical and neonatal complications occurred respectively in 35.0 % (95 % CI [28.3 - 41.7]) and 37.0 % (95 % CI [30.3 - 43.7]) of pregnancies. All complications were more frequent amongst cardiomyopathies or obstructive and conotruncal lesions, whereas left-to-right shunts were less prone to present with complications...

Post-spinal hypotension remains a common and clinically-important problem during caesarean section, and accurate pre-operative prediction of this complication might enhance clinical management. We conducted a prospective, single-centre, observational study of heart rate variability in 102 patients undergoing elective caesarean section in a South African regional hospital. We performed Holter recording for ≥ 5 min in the hour preceding spinal anaesthesia. The low-frequency/high-frequency ratio component of heart rate variability was compared, using a logistic regression model, with baseline heart rate and body mass index (BMI) as a predictor of hypotension (defined as systolic arterial pressure < 90 mmHg) occurring from the time of spinal insertion until 15 min after delivery of the baby...

BACKGROUND: Takotsubo syndrome (TS) is an acute cardiac condition with a substantial mortality for which no specific treatment is available. We have previously shown that isoflurane attenuates the development of left ventricular (LV) dysfunction in an experimental TS-model. We compared the effects of equi-anaesthetic doses of isoflurane, propofol and ketamine+midazolam on haemodynamics, global and regional LV systolic function and the activation of intracellular metabolic pathways in experimental TS...

BACKGROUND: Perioperative respiratory adverse events (PRAE) are the most common critical incidents in paediatric anaesthesia and occur more often in infants. Use of laryngeal mask airways (LMAs) is associated with reduced PRAE compared with endotracheal tubes in older children (>1 year). We aimed to evaluate the effect of these devices on the incidence of PRAE in infants. METHODS: We did a randomised controlled trial at the Princess Margaret Hospital for Children in Perth (WA, Australia) by recruiting infants (aged 0-12 months) undergoing general (with or without regional or local) anaesthesia with anticipated fentanyl dose 1 μg/kg or lower for minor elective surgery...

BACKGROUND: The continuous monitoring of vital parameters and subsequent therapy belong to the core duties of anaesthetists during acute trauma resuscitation in the trauma room. Important procedures may include placement of arterial lines and central venous catheters (CVCs). Knowledge of indication, performance and localization of invasive catheterisation of trauma care in Germany is scarce. METHODS: After approval of the German Society of Anaesthesiology and Intensive Care Medicine we conducted an online survey about arterial and central venous catheterisation of severely injured patients with consideration of common practice used by anaesthetists in German trauma rooms...

BACKGROUND: Neurosurgical operations in the dorsal cranium often require the patient to be positioned in a sitting position. This can be associated with decreased cardiac output and cerebral hypoperfusion, and possibly, inadequate cerebral oxygenation. In the present study, cerebral oxygen saturation was measured during neurosurgery in the sitting position and correlated with cardiac output. METHODS: Perioperative cerebral oxygen saturation was measured continuously with two different monitors, INVOS(®) and FORE-SIGHT(®)...

Neuraxial anaesthesia is widely used in obstetrics and neurological complications are rare. However, when they occur, subsequent investigation and management are time-critical and correlate with the extent of neurological recovery. The Third National Audit Project recommended the implementation of guidelines in obstetric epidural management, including advice on monitoring for early signs of problems and acting upon concerns. However, no national guideline exists for postoperative management in the obstetric population...

REVIEW
K Ode, S Selvaraj, A F Smith
This review attempts to draw on the published literature to address three practical clinical questions. First, what means of testing the degree of regional blockade pre-operatively are available, and can eventual success or failure be determined soon after injection? Second, is it possible to predict if a block inserted after the induction of general anaesthesia will be effective when the patient wakes? Third, what features, and what duration, should cause concern when a block does not resolve as expected after surgery? Although the relevant literature is limited, we recommend testing of multiple sensory modalities before surgery commences; temperature and thermographic changes may offer additional early warning of success or failure...

BACKGROUND: The anaesthetic technique may influence clinical outcomes, but inherent confounding and small effect sizes makes this challenging to study. We hypothesized that regional anaesthesia (RA) is associated with higher survival and fewer postoperative organ dysfunctions when compared with general anaesthesia (GA). METHODS: We matched surgical procedures and type of anaesthesia using the US National Surgical Quality Improvement database, in which 264,421 received GA and 64,119 received RA...

INTRODUCTION: Regional anaesthesia is commonly preferred for arteriovenous fistula (AVF) creation. Previous studies suggest a shorter block duration in patients with chronic renal failure, maybe because of the changes in regional blood flow. The aim of our study was to evaluate the duration of the axillary block with 1.5% mepivacaine in patients with chronic renal failure scheduled for AVF compared with healthy controls. METHODS: Patients scheduled for AVF creation for the first time (GIRC) were included...

BACKGROUND: In recent years, the incidence of urinary stone disease reportedly has been increasing. The use of shockwave lithotripsy has seen low success rates, the inefficacy of a single session, and the need for general anaesthesia in children; additionally, children are exposed to radiation. These suboptimal treatment conditions have all led to ureteroscopy (URS) becoming the treatment method of choice for paediatric ureter stones. The aim of this study is to examine the effectiveness of 4...

BACKGROUND: Ultrasound-guided nerve blocks have become the standard when performing regional nerve blocks in anaesthesia. Infiniti Plus (CIVCO Medical Solutions, Kalona, Iowa, USA) is a needle guide that has been recently developed to help clinicians in performing ultrasound-guided nerve blocks. OBJECTIVES: We tested the hypothesis that femoral nerve catheter placement carried out with the Infiniti Plus needle guide will be quicker to perform than without the Infiniti Plus...
