Etude clinique de la crème anesthésique EMLA en anesthésie locorégionale pédiatrique

Abstract

The advantage of EMLA cream for regional blocks (spinal or caudal blocks) was assessed in 46 children. The study included three groups : group 1, with 1 to 6 month-old children (n = 11) ; group 2, with children aged between 6 months and 5 years (n = 21), scheduled for emergency surgery and with full stomach ; group 3, with 5 to 10 year-old children (n = 14), who were to have a regional block as an alternative to general anaesthesia. The cream was applied as a thick layer on the area of skin to be anaesthetised and covered by a closed adhesive dressing, approximately 2.2 h before performing the regional block. A dose of 1 to 2 g was used in children of more than 1 year, and 0.5 to 1 g for those of less than 1 year. All the blocks were carried out by the same anaesthetist. The technique was considered as being little (45/46) or not constraining (1/46). Patient cooperation in carrying out the regional block was judged to be good or very good in 34/46 children. Additional sedation was required in 7 children of groups 2 and 3. The block was as easy to carry out as usual in 37/46 children. In all threen groups, most children complained of little or no pain. Local adverse effects occurred in 19/46 patients, consisting of erythema (14), skin paleness (4), or both (1). The investigator qualified the use of EMLA cream as satisfactory or very satisfactory in 36/46. It is concluded that EMLA cream provides convenient analgesia for regional blocks in toddlers and children.
