Introduction:Erector spinae plane block (ESPB) is a recently described technique (2016); its use as continuous analgesia with an intrafascial catheter in anterior scoliosis surgery for pediatric patients in intensive care unit (ICU) has not been reported in the literature.Objective: To describe the use of an intrafascial catheter in the erector spinae for continuous infusion and patient-controlled analgesia as a postoperative analgesic technique in anterior scoliosis surgery.Clinical Case: 15-year-old patient weighing 34 kg, diagnosed with scoliosis with 110° Cobb angle in the context of neurofibromatosis, subjected to anterior corrective surgery with continuous analgesia and patient-controlled analgesia through an intrafascial catheter in the erector spinae.Conclusions: The use of continuous intrafascial analgesia and patient-controlled analgesia in the erector spinae provided adequate analgesic control in the postoperative period of corrective anterior scoliosis surgery in a pediatric patient in ICU.
