Review[Perioperative analgesia with continuous peripheral nerve blocks in children].
Recently, regional anaesthesia in children has generated increasing interest. But single injection techniques have a limited duration of postoperative analgesia. Then, continuous peripheral nerve blocks have taken an important position in the anaesthetic arsenal, allowing an effective, safe and prolonged postoperative pain management. ⋯ Finally, ropivacaine appears to be the most appropriate drug for continuous peripheral nerve blocks in children, requiring low flow rates and concentrations of local anaesthetic. These techniques may facilitate early ambulation by an improved pain management or even postoperative analgesia at home with disposable pumps. One might infer from the current review that excellent pain relief coupled with a reduction of side effects would contribute to improve the quality of life and to decrease the frequency of disabling behavioural modifications in children, sometimes psychologically injured by hospital stay and postoperative pain.

Comparative Study[Reliability and survival of arterial catheters: optimal dynamic response].
Blood pressure is one of the most critical haemodynamic parameter in the intensive care unit (ICU). The measurement relies mainly on invasive methods (arterial lines) but also on noninvasive methods (Oscillometric and Manual). It is crucial to be instantaneous and accurate to adapt any decision making plan. The aim of this study is to evaluate the reliability of this measure given by an arterial catheter over time. This can determine the maintenance of catheter patency before clinical total occlusion. ⋯ The measure of the arterial blood pressure invasively can still be reliable for a long period of time (10 days), as long as the catheter is inserted, especially when the mean arterial pressure is considered. Each time the distance of the catheter insertion site moves away 1 cm from the radiocarpal joint or the groin, the risk of troubleshooting is doubled; on each blood sample from the catheter, this risk is reduced by 20%.

Controlled Clinical Trial[Evaluation of postoperative analgesia with continuous iliofascial nerve sheath block after total hip arthroplasty replacement: a pilot study].
To assess the analgesic efficiency of a continuous iliofascial nerve sheath block after total hip arthroplasty replacement (RPTH). ⋯ After RPTH surgery, continuous iliofascial block reduces morphine consumption; provide a better pain relief at rest and on movement than IV multimodal analgesia alone.
