The analgesic efficacy and safety of propacetamol (Pro-Dafalgan), an injectable prodrug of acetaminophen, in combination with morphine administered by patient-controlled analgesia (PCA) were studied in 60 patients (56 men, 4 women; age 18-40 years; mean age, 26 years) after knee ligamentoplasty. Using a double-blind, randomized, parallel-group design, the(More)
Anaesthesia is a medical act which eliminates the feeling of pain as well as the motor reactions of a person, before performing a surgical operation. Loco-Regional Anaesthesia (LRA) concerns only a part of the body such as the front arm or leg. This practice is increasingly used today notably because the patient can remain conscious and can recover more(More)
Ultrasound guided regional anesthesia (UGRA) is steadily growing in popularity, owing to advances in ultrasound imaging technology and the advantages that this technique presents for safety and efficiency. The aim of this work is to assist anaesthetists during the UGRA procedure by automatically detecting the nerve blocks in the ultrasound images. The main(More)
BACKGROUND Tibial and common peroneal nerves can be blocked by the posterior approach to the popliteal fossa. Techniques using fixed measured distances between knee skin crease and puncture point have been described. We report on an approach that is based on manual identification of the apex of the popliteal fossa. METHODS Five-hundred patients undergoing(More)
BACKGROUND During interscalene block (ISB) placement, ultrasound guidance (USG) enables the practitioner to measure the spread of local anesthetic around the nerve trunks or roots, and to adjust the needle position in order to optimize diffusion. Moreover, USG helps determine the best injection level, i.e. the point from which diffusion gives the most(More)
Ultrasound in regional anesthesia (RA) has increased in popularity over the last years. The nerve localization presents a key step for RA practice, it is therefore valuable to develop a tool able to facilitate this practice. The nerve detection in the ultrasound images is a challenging task, since the noise and other artifacts corrupt the visual properties(More)
The leading advantage of Ultrasound-Guided Regional Anesthesia (UGRA) is the ability to visualize the anatomical structure of interest. The nerve detection should translate into greater efficacy, by ensuring accurate deposition and spread of local anesthetic around the target nerve. The identification of nerve is among the most difficult tasks that(More)
