Despite widespread use of ultrasound imaging to guide needle placement, the incidence of transient and permanent nerve damage as a complication of regional anaesthesia has not changed over the last decade. In view of the controversy surrounding intraneural injection there is a need to understand the structural changes caused by subepineural and subperineural needle penetration. Clinical ultrasound machines do not provide adequate anatomical resolution, and anaesthetists have difficulty judging the precise location of the needle tip relative to the epineurium...

BACKGROUND: Carotid endarterectomy carries a significant risk of intraoperative brain ischaemia. Various methods for intraoperative cerebral function monitoring can be utilized, but the assessment of the patient's consciousness remains the easiest and most available method, requiring that the patient remain awake and under local/regional anaesthesia. The aim of this study was to compare infiltration anaesthesia with an ultrasound-guided superficial/combined cervical plexus block for patient safety and comfort...

Regional anaesthesia provides effective anaesthesia and analgesia in the perioperative setting. Central neuraxial blocks-that is, spinal and epidural blocks-are well established as an alternative or adjunct to general anaesthesia. Peripheral blocks may be used as part of multimodal anaesthesia/analgesia in perioperative practice, reducing the need for opioid analgesics and enhancing early recovery. Furthermore, regional anaesthesia has increased in popularity and may be done with improved ease and safety with the introduction of ultrasound-guided techniques...

The practice of regional anaesthesia is rapidly changing with the introduction of ultrasound into the working domain of the anaesthesiologist. New techniques are being pioneered. Among the recent techniques, notable are the truncal blocks, for example, the transversus abdominis plane block, rectus sheath block, hernia block and quadratus lumborum block in the abdomen and the pectoral nerves (Pecs) block 1 and 2, serratus anterior plane block and intercostal nerve block. This narrative review covers the brief anatomical discourse along with technical description of the ultrasound-guided truncal blocks...

PURPOSE: Systematic transrectal ultrasound biopsies have been the first-line biopsy strategy in men with suspected prostate cancer for over 30 years. Transperineal biopsy is an alternative approach but has been predominately reserved as a repeat biopsy strategy and not widely used as a first-line approach. This study evaluates the diagnostic and clinical outcomes of transperineal sector biopsy (TPSB) as a first-line biopsy strategy in the diagnosis and management of prostate cancer. MATERIALS AND METHODS: A multi-institutional review of 402 consecutive patients who underwent primary transperineal sector biopsy...

BACKGROUND: Regional anaesthesia comprising axillary block of the brachial plexus is a common anaesthetic technique for distal upper limb surgery. This is an update of a review first published in 2006 and previously updated in 2011 and 2013. OBJECTIVES: To compare the relative effects (benefits and harms) of three injection techniques (single, double and multiple) of axillary block of the brachial plexus for distal upper extremity surgery. We considered these effects primarily in terms of anaesthetic effectiveness; the complication rate (neurological and vascular); and pain and discomfort caused by performance of the block...

Thoracic paravertebral blocks (TPVBs) have an extensive evidence base as part of a multimodal analgesic strategy for thoracic and breast surgery and have gained popularity with the advent of ultrasound guidance. However, this role is poorly defined in the context of abdominal surgery. We performed a systematic review of randomized controlled trials, to clarify the impact of TPVB on perioperative analgesic outcomes in adult abdominal surgery. We identified 20 published trials involving a total of 1044 patients that met inclusion criteria; however there was significant heterogeneity in terms of type of surgery, TPVB technique, comparator groups and study quality...

It has been suggested for many years that regional anaesthesia is advantageous in high-risk patients, either as the sole anaesthetic or in combination with general anaesthesia. Regional techniques are safe and even more so when guided by ultrasound. In the high-risk patient population, ultrasound-guided regional anaesthesia (UGRA) can help decrease risk of perioperative morbidity and improve short-term as well as long-term outcomes, particularly in the orthopaedic, vascular, oncologic and chronic pain patient populations...

BACKGROUND: The knowledge on the type and influence of visuospatial ability on sonography performance relevant for ultrasound-guided regional anaesthesia remains incomplete. The aim of this study was to determine whether four different factors of visuospatial ability are important in determining proficiency and procedure time of novices performing brachial plexus sonography. These factors were spatial visualisation, flexibility of closure, spatial relations and speed of closure. METHODS: Thirty-three ultrasound novices were recruited in this prospective, observational trial...

Neurilemmomas-or schwannomas-are rare soft tissue tumours involving peripheral nerve sheaths, usually found in the head and neck regions. They can infrequently originate within the tissues of the abdominal wall. Here, we present a case of symptomatic schwannoma of the abdominal wall in a 62-year-old woman referred for abdominal pain in the right iliac fossa. On physical examination, a 5-7-cm oval-shaped area of consolidation with regular borders and elastic consistence was palpable. Ultrasound examination of the abdomen revealed a hypoechogenic mass measuring 80-33-42 mm; subsequently, a CT scan confirmed the presence of a well-circumscribed mass, with small calcifications inside...

We report on a 21-year-old pregnant Greenlandic Inuit woman, who presented at a small local hospital in Northern Greenland. The patient suffered from lower abdominal pain, irregular bleeding and vomiting. urine-human chorionic gonadotropin (U-hCG) was positive. Ultrasonography showed the typical 'snow-storm' images of a mole pregnancy. Owing to the fact that local physicians were able to perform an ultrasound, proper diagnosis could be established, and the patient was transferred to the regional hospital, located nearly 1200 km away...

The Direct Observation of Procedural Skills (DOPS) form is used as a workplace-based assessment tool in the current Australian and New Zealand College of Anaesthetists curriculum. The objective of this study was to evaluate the reliability of DOPS when used to score trainees performing ultrasound-guided regional anaesthesia. Reliability of an assessment tool is defined as the reproducibility of scores given by different assessors viewing the same trainee. Forty-nine anaesthetists were recruited to score two scripted videos of trainees performing a popliteal sciatic nerve block and an axillary brachial plexus block...
