Editorial Commentary: Pain After Hip Arthroscopy-Are We Truly Addressing the Problem?

Pain after hip arthroscopy is a significant and challenging issue as is evidenced by the number of publications on this subject. Various analgesic strategies to circumvent this issue have been tried, with variable results. The central problem is that pain experienced by patients after hip arthroscopy is multifactorial in origin. Regarding local injection, an anatomic approach to the nerve supply to the hip with an effective pain relief strategy should take this into consideration and focus on using drugs with a low risk of complications and infiltration techniques that do not cause an unnecessary delay in rehabilitation and discharge of the patient. Furthermore, addressing traction time, surgical technique, and fluid extravasation and applying an individualized approach, keeping the patient's personality and profile in mind, will ensure adequate analgesia after arthroscopic intervention.

Spatial mapping of the brachial plexus using three-dimensional ultrasound.

Imaging of the brachial plexus with MRI and standard two-dimensional (2D) ultrasound has been reported, and 2D ultrasound-guided regional anaesthetic block is an established technique. The aim of this study was to map the orientation of the brachial plexus in relation to the first rib, carotid and subclavian arteries, using three-dimensional (3D) ultrasound. A free-hand optically tracked 3D ultrasound system was used with a 12 MHz transducer. 10 healthy volunteers underwent 3D ultrasound of the neck. From the 3D ultrasound data sets, the outlines of the brachial plexus, subclavian artery and first rib were manually segmented. A surface was interpolated from the series of outlines to produce a spatially orientated 3D reconstruction of the brachial plexus. The brachial plexus could be mapped in all volunteers, although a variation in image resolution between individuals existed. Anatomical variations were demonstrated between the 10 volunteers; the most notable and clinically relevant was the alignment of the plexus divisions. 3D reconstructions illustrated the plexus, changing its orientation from a vertical alignment in the interscalene region to a more horizontal alignment in the supraclavicular fossa. Spatial mapping of the brachial plexus is possible with 3D ultrasound using the subclavian artery and first rib as landmarks. There is a deviation from the conventionally described anatomy and this may have implications for the administration of regional anaesthesia.

Postoperative shoulder surgery initiative (POSSI): an interim report of major shoulder surgery as a day case procedure.

BACKGROUND: There are logistical and financial advantages to undertaking shoulder surgery in a day case setting. However, this approach is limited by postoperative pain being inadequately controlled by oral medication alone. We describe a pilot study investigating the feasibility and acceptance of community based continuous interscalene brachial plexus blockade (CIBPB) to provide effective analgesia for day case shoulder surgery. METHODS: Phase 1 consisted of five patients who received CIBPB for shoulder surgery. Following an overnight hospital stay they were assessed for discharge home with the interscalene catheter in situ. Once the safety and feasibility of the approach was documented, five more patients were recruited to Phase 2. These patients had the adequacy of analgesia assessed in the postoperative period and were discharged home on the same day as surgery. A district nurse visited twice daily and removed the catheter on the third day. Patient satisfaction was assessed using a discovery interview. RESULTS: Nine of the 10 patients experienced good analgesia. One patient was re-admitted because the catheter fell out. No patient experienced complications and the discovery interviews showed that the patients were satisfied with their management and pleased to be treated as a day case. CONCLUSIONS: POSSI proved that it was feasible to manage these patients in the community with support and training of the district nurses. Although extra community nursing hours are required, this technique has the potential for significant cost benefits with at least three bed days saved per patient.

Deliberate release of biological agents.

Deliberate release of biological agents is a growing threat, but clinical recognition of the resulting diseases is hampered by their rarity and similar presentation to more common illnesses. Despite substantial publicity, access to information may be difficult. Further, the available data are fragmented and not always relevant to critical care settings. We describe the clinical presentations of some important infections, highlighting the features that are relevant to critically ill patients. We provide an integrated set of guidelines for diagnosis, patient care and infection control and have attempted to list important print- and web-based resources for further information.
