[Short version of recommendations for enhanced recovery program (ERP) for cystectomy: Technical measures]. / Version courte des recommandations de la récupération ameliorée après chirurgie (RAAC) pour la cystectomie : mesures techniques.

INTRODUCTION: The enhanced recovery program (ERP) is a management mode whose objective is to reduce the risk of complications and allow the patient to recover more quickly all its functional capacities and to reintegrate at most quickly and safely in his usual environment. This intentionally synthetic document aims to disseminate in the urological community the main points of the ERP recommendations for cystectomy. This work, coordinated by AFU, involves several other partners. The full document is available on the "Urofrance" website. Another article will follow on organizational measures. METHOD: The development of the recommendations is based on the method "formalized consensus of experts" proposed by the HAS. The report is based on a systematic review of the literature (January 2006-May 2017), two rounds of iterative quotations and a national proofreading. Levels of proof of conclusions and gradation of recommendations are based on the HAS grid. RESULTS: The bibliographic strategy made it possible to retain 298 articles. Only the recommendations that obtained a strong agreement after the two rounds of iterative listing were retained. The recommendations presented here are in chronological form (before, during, after hospitalization). Twenty-six key points on the technical and organizational measures of ERP have been identified. CONCLUSION: The result of the literature review, supplemented by expert opinion, suggests a significant clinical interest in the application and dissemination of ERP for cystectomy, despite the limited data available for this indication.

[Arthroscopic shoulder surgery and ischemic cerebral complications]. / Chirurgie arthroscopique de l'épaule et complications ischémiques cérébrales.

The authors report three cases in which cerebral ischemia occurred during arthroscopic shoulder surgery performed in beach chair position under general anaesthesia and interscalene plexus block. Several similar cases have been published in the literature. This rare but extremely severe complication is related to the decrease in cerebral perfusion pressure (CPP). Monitoring of CPP in the beach chair position using the measurement of arterial pressure and taking into account the hydrostatic gradient is essential. Prevention includes correction of preoperative hypovolaemia, treatment of postural arterial hypotension, adequate installation of the patient's head, aggressive treatment of perioperative arterial hypotension (whatever the cause) and avoidance of deliberate perioperative arterial hypotension. Routine use of non-invasive monitoring of cerebral oxygenation has been advocated to avoid this accident but its usefulness has to be confirmed by clinical studies.

[Ultrasound and regional anaesthesia]. / Echographie et anesthésie locorégionale.

The use of ultrasound is the latest major evolution in regional anaesthesia. Review of available literature shows significant changes in clinical practice. Ultrasound guidance allows the visualization of anatomical variations or unsuspected intraneural injections, reduces the volume of local anaesthetic injections and confirms correct local anaesthetic distribution or catheter placement. No study has found a statistical difference in success rates and safety because all studies were underpowered. However, the ability to visualize an invasive procedure that has been performed blindly in the past is an undeniable progress in terms of safety. The necessity to be familiar with the machine and the learning curve can be repulsive. The aim of this article is to demystify ultrasound guidance by explaining the fundamentals of the clinical use of ultrasound. With the help of different chapters, the authors explain the different adjustments and possible artefacts and give easy solutions for the use of bedside ultrasound. Training is essential and can be performed on manikins or training phantom. For each region the main anatomical landmarks are explained. One must be familiar with several imaging techniques: short axis (transverse) or long axis (longitudinal) nerve imaging, in-plane or out-of-plane imaging and hydrolocalization. Viewing the needle's tip position during its progression remains the main safety endpoint. Therefore, electrical nerve stimulation and ultrasound guidance should be combined, especially for beginners, to confirm proximity to neural structures and to help in case of difficulty. Optimizing safety and clinical results must remain a key priority in regional anaesthesia. Finally, specific regulations concerning the transducers are described. Paediatric specificities are also mentioned.

Sedation with target-controlled propofol infusion during shoulder surgery under interscalene brachial plexus block in the sitting position: report of a series of 140 patients.

BACKGROUND AND OBJECTIVE: The aim of this study was to assess target-controlled propofol infusion as a technique of sedation for shoulder surgery under interscalene brachial plexus block in the sitting position and to evaluate the effect of sedation on hypotensive/bradycardic events during this procedure. METHODS: One hundred and forty patients undergoing elective shoulder surgery in the sitting position under interscalene brachial plexus block (with 30 mL of ropivacaine 0.75%) were prospectively enrolled. All patients were premedicated with hydroxyzine 1 mg kg(-1), none received beta-blockers. No patients were given atropine except for the patients who experienced a vasovagal event either during the block procedure or intravenous catheter placement. The target-controlled propofol infusion was started immediately after positioning the patient on the operating table. The initial target concentration was 1 microg mL(-1). The infusion rate was adjusted every 15 min by increasing or decreasing the target concentration by 0.2 microg mL(-1) steps to maintain the patient rousable to verbal commands (score of 3 on Wilson sedation scale). The following parameters were assessed: minimal, maximal, optimal target concentration, respiratory and haemodynamic parameters, total propofol dose, additional alfentanil needs, occurrence of hypotensive/bradycardic events, complications. Results are mean +/- SD. Statistical analysis used t-test and chi2-tests. RESULTS: The optimal propofol target concentration was 0.8 mug mL(-1). No respiratory complications or conversion to general anaesthesia was reported. Two patients experienced transient and inconsequential intraoperative agitation. The incidence of hypotensive/bradycardic events during the procedure was 5.7% (eight patients). CONCLUSION: Target-controlled propofol infusion (0.8-0.9 microg mL(-1)) following hydroxyzine premedication is a safe and effective technique for sedation when combined with interscalene brachial plexus block during shoulder surgery in the sitting position.
