Single Crystal Based Ultrasound Actuated Needle For Regional Anaesthesia and Biopsy
Ultrasound guidance of needle-based regional anaesthesia and tissue biopsy is widely used in clinical practice. Ultrasound imaging has improved the efficacy and reduced some side effects during regional nerve block. However, the presentation and interpretation of real-time ultrasound guided needle …

Enhanced biopsy and regional anaesthesia through ultrasound actuation of a standard needle
… needle-based interventional procedures including regional anaesthesia and cancer biopsy. In ultrasound guided percutaneous needle procedures, there is a universal problem of imaging the needle, particularly the tip, especially in dense tissues and steep insertion angles. Poor visualization of the …

Study of damage to peripheral nerves caused by anaesthetic needles during regional anaesthesia
… is strongly recommended for the safe conduct of regional anaesthesia procedures. It is safe, now has adequate spatial resolution and provides real time visualization of local anaesthetic spread. However, the risk of nerve trauma still remains. A recent meta-analysis of randomized controlled …

Informed consent for peripheral nerve blocks at a tertiary level hospital in South Africa: a quality improvement project
… whether or not to consent to the treatment. Regional anaesthesia, including peripheral nerve blocks (PNBs), provides a plethora of benefits to patients undergoing surgery but, due to potential risks involved, also requires informed consent. Studies have shown that South African anaesthetists …

Long term potential of a saturated sodium chloride solution for the anatomical preservation of human cadavers
… as a training model for ultrasound-guided regional anaesthesia (USGRA). The saturated NaCl solution method conferred long-lasting preservation of structures with retention of tissue colour and pliability; however, the rapid onset of deterioration occurred when gross dissection began. The …

Anxiety and it's management during awake procedures in operating theatres. A survey and randomised controlled trial.
… these specialities are performed under local or regional anaesthesia. The study consists of two distinct stages. The first stage was a postal survey of patients (n=213) who had undergone awake plastic, renal access or carotid surgery up to two weeks previously, in order to determine …

Models for Testing Contemporary Ultrasound Systems
… two specific case studies on ultrasound guided regional anaesthesia.<br/>Another aspect considered in this work is the suitability of Thiel-embalmed human breast tissues for testing therapeutic ultrasound systems. The results indicate that these models are unsuitable for therapeutic ultrasound …

Coagulation in the HIV-positive pregnant patient: A thromboelastographic study
… and HIV receiving anti-retroviral medication. Regional anaesthesia is the technique of choice for caesarean section, and is contraindicated in a hypo-coagulable state. We therefore investigated the coagulation status of term pregnant women with HIV, presenting for elective caesarean …

Prehospital pain management in mass casualty scenarios: a scoping review
… cases receiving pain medication. Ketamine and regional anaesthesia emerged as viable options, particularly in resource-limited settings, while novel delivery systems like autoinjectors showed promise. Major barriers included resource shortages, provider training gaps, and limited integration of …

The Mechanism of Action of Lidocaine and Levobupivacaine on Human Cardiac Voltage-gated Na<sup>+ </sup>Channels Na<sub>V</sub>1.5
… may contribute to a direct mechanism by which regional anaesthesia during tumour resection reduces subsequent cancer recurrence. Metastatic colon cancer cells express adult and neonatal NaV1.5 splice variants. Lidocaine and levobupivacaine are amide local anaesthetics that are widely used in …

Perioperative ultrasound among South African anaesthetists: a survey of current practice and availability
… an online REDCap survey. All doctors practising anaesthesia in South Africa were eligible. Recruitment was done via an email link that was sent to South African Society of Anaesthesiologists (SASA) members. Non-SASA members were recruited via departmental mailing lists or social media. Results: …

Paediatric regional anaesthetic procedures: clinical anatomy competence, pitfalls and complications
… various specialities, including the practice of regional anaesthetic procedures on paediatric patients. The competency that a doctor displays in clinical procedures is an important aspect of their overall clinical competence and the successful performance of regional blocks demands a working and …

Training in and assessment of the procedural skills required to perform peripheral nerve blockade
… on novices of varied years of experience in anaesthesia (i.e. the present training programmes / courses of an intense training day for one or more procedures). There was a marked attrition of skill at 24 hours with a significant correlation with increasing years of experience; there also …
