regional anesthesia for totally awake upper limb surgery in pediatric population

Conditions: Surgery; Anesthesia, Local; Pediatric ALL

Summary: peripheral loco-regional anesthesia (lra) for anesthetic purposes is a technique widely used in adults for upper limb surgery. in pediatrics, lra is not classically considered on its own. it is usually performed for analgesic purposes during sedation or general anesthesia. it is entirely possible to carry out awakened peripheral blocks in communicating children, of school age, thus avoiding the issues of ga in pediatrics, in particular in an emergency context. the use of emla anesthetic skin patches for punctures (perfusion and lra) as well as the viewing of cartoons on touch tablets during treatment can improve the perception of painless care such as lra and treatment. in pediatrics, only ropivacaine at a concentration of 0.2% has marketing authorization in pediatrics in children under 12 for the production of peripheral blocks. on the basis of the experience of the claude galien private hospital in this area, it seems interesting to assess the feasibility of upper limb surgery under anesthetic lra alone with a dose of ropivacaine at the concentration 0.35% in communicating children, of school age.

peripheral loco-regional anesthesia (lra) for anesthetic purposes is a technique widely used in adults for upper limb surgery. it allows peripheral surgeries to be performed without putting the patient to sleep and thus avoiding certain disadvantages of general anesthesia (ga). in pediatrics, lra is not classically considered on its own. it is usually performed for analgesic purposes during sedation or ga. subject to respecting a strict protocol and taking advantage of considerable developments in the field of lra, it is entirely possible to carry out awakened peripheral blocks in communicating children, of school age, thus avoiding the pitfalls of ga in pediatrics, in particular in an emergency context (inhalation on a full stomach, respiratory risk in children with colds, inhalational anesthesia with an anxiety mask, postoperative vomiting nausea, disorientation and delusions upon waking ...) indeed, the exclusive use of ultrasound, the use of adapted needles, the improvement of knowledge in sono-anatomy, the reduction in doses and concentrations of local anesthetics are all developments in the field of lra allowing to improve the conditions of safety, comfort for the patient and success of the technique. beyond technical considerations, there are ways to improve the child's experience with care. the use of emla anesthetic skin patches for punctures (perfusion and alr) as well as the viewing of cartoons on touch tablets during treatment can improve the perception of painless care such as alr and treatment. charge in the operating room. in pediatrics, only ropivacaine at a concentration of 0.2% has marketing authorization in pediatrics in children under 12 for the production of peripheral blocks. higher concentrations of ropivacaine, used in several pediatric studies, have nevertheless shown their good tolerance and their efficacy under reserve not to exceed 3mg / kg and to use concentrations up to 0.5% on the basis of these arguments, and with the experience of the claude galien private hospital in this area, it seems interesting to assess the feasibility of upper limb surgery under anesthetic alr alone with a dose of ropivacaine at the concentration 0.35% in communicating children, of school age.
