Adequate pre-operative analgesia for elderly patients with femoral neck fractures is difficult to assess and is often an overseen aspect of their care. We aimed to assess the efficacy of fascia iliaca blocks inserted via plexus blockade catheters in the pre-operative period. Our simple technique allowed the block to be administered safely without the need for a nerve stimulator. ⋯ Visual analogue scores also score improved significantly from 7.2 to 4.6 (S. D. 2.4) in the 18 patients without cognitive impairment. We conclude that fascia iliaca blocks can provide significant benefit in the pre-operative period and allow patients to sit up more comfortably while they await surgery.

High resolution ultrasound is a new method for detecting anatomical structures in the axilla. The visualisation of nerves can improve the quality of nerve blocks. The aim of our study was to investigate the feasibility of hand held ultrasound to perform sonographically guided blockades of the axillary plexus. ⋯ Performing axillary nerve blockade using ultrasound guidance provides excellent anaesthesia and fast onset times.

A magnetic resonance imaging analysis of the infraclavicular region: can brachial plexus depth be estimated before needle insertion?
In this study we examined the anatomy of the infraclavicular region to assess the possibility of estimating brachial plexus depth before performing an infraclavicular block, by using readily identifiable landmarks such as the coracoid process (CP) and the clavicle (CL). Four parasagittal planes across the infraclavicular region were analyzed in 21 individual series of magnetic resonance imaging studies. Measurements included distance to the plexus from the skin of the anterior chest wall, position of the plexus relative to the CL, and clavicular width. ⋯ Furthermore, not only is it uncommon to find the lung in this same parasagittal plane, but when it does appear, it is well behind the plexus. Estimating plexus depth, or "depth gauging," in the infraclavicular region is achievable and is a potentially useful strategy. Further study is required to confirm this finding in the clinical environment.

Case Reports[Treating pain related to inoperable pancreatic cancer in tropical areas: the advantage of CT-guided celiac plexus block and splanchnic nerves neurolysis].
Many sub-Saharan African countries have recently acquired computed tomography scanners that make interventional radiology possible, especially for the treatment of cancer pain. We report the case of a patient with severe abdominal pain related to advanced pancreas cancer. After unsuccessful morphine treatment, he underwent CT-guided alcohol injection for neurolysis of the celiac plexus and splanchnic nerves. This report describes the technique and discusses its potential applications in tropical countries.
