Randomized Controlled Trial Clinical Trial
Alkalinisation of lignocaine to reduce the pain of digital nerve blockade.
To see if the alkalinisation of lignocaine caused a reduction in the pain of injection for digital nerve blockade. ⋯ Alkalinisation of lignocaine reduces the pain of injection for digital nerve blockade.

Randomized Controlled Trial Clinical Trial
Dorsal penile nerve block in children undergoing circumcision in a day-care surgery.
Circumcision is performed under general anaesthesia (GA) with dorsal penile nerve block (DPNB) as an analgesic technique for postoperative pain. The purpose of this study was to compare DPNB as the sole anaesthetic procedure vs GA and DPNB for circumcision in children as an outpatient procedure. ⋯ These data confirm that DPNB has advantages over GA + DPNB for paediatric circumcision in day-care surgery.

There is a clinical requirement for longer-acting local anesthetics, particularly for the management of post-operative and chronic pain. In this regard, liposomes have been suggested to represent a potentially useful vehicle for sustained drug release after local administration. In the current study, the authors used a transmembrane pH gradient to efficiently encapsulate bupivacaine within large unilamellar vesicles. They report on the kinetics of drug uptake and release and the duration of nerve blockade. ⋯ Large unilamellar vesicles that exhibit a pH gradient can efficiently encapsulate bupivacaine and subsequently provide a sustained-release system that greatly increases the duration of neural blockade.

Sciatic nerve block in the popliteal fossa (popliteal nerve block, PNB) is an anaesthetic technique well-suited for operations below the knee. However, difficulty with positioning the patient in the prone position often precludes the classical, posterior approach to the block. In this report, an alternative approach to PNB that can easily be performed with a patient in the supine position is described. ⋯ The supine approach to PNB allows the use of the block in patients that cannot be positioned in the prone position. Flexion of the leg at the knee greatly facilitates identification of the anatomical landmarks. When combined with a block of the femoral or saphenous nerve, this technique provides excellent anaesthesia for patients undergoing foot and ankle surgery.

Regional nerve blocks are a valuable skill for general practitioners and surgeons who perform surgical procedures under local anaesthetic. Once mastered, these injections provide rapid anaesthesia with minimal pain, little distortion of the tissues and improved aesthetic results. This paper describes techniques applicable to lesions of the face, upper and lower limbs, and to achieve anaesthesia after a fractured rib.
