This study aims to evaluate the influence of ultrasound-guided erector spinae plane block on postoperative pain and diaphragmatic dysfunction in pediatric patients undergoing thoracoscopic sympathectomy.
Pain may occur after pediatric thoracic surgery in cases such as skin incision creation, rib traction, and drain placement, and in other cases, such as rib nerve injury. Such pain is highly unfavorable to pediatric patients' recovery as it may lead to reduced cough strength for clearing secretions, decreased functional residual capacity, and pulmonary complications such as atelectasis and pneumonia. Erector spinae plane block (ESPB) is a novel trunk block to relieve chronic neuropathic pain. Since then, it has gained prominence as a regional anesthesia technique with the potential to revolutionize postoperative pain management, and it has been effectively administered not only for the management of perioperative pain for a wide variety of surgeries but also for the management of acute post-traumatic pain and chronic pain.

RECRUITINGDegree of pain
Postoperative pain assessment with the numeric rating scale (NRS) score. NRS (0 represents "no pain" while 10 represents "the worst pain imaginable"). NRS will be assessed on arrival at the post-anesthesia care unit (PACU), 1, 2, 4, 8, 12, and 24 h postoperatively.
Time frame: 24 hours postoperatively
Total analgesic consumption
Total analgesic consumption will be recorded.
Time frame: 24 hours postoperatively
Anesthetic consumption: minimum alveolar concentration
Anesthetic consumption: minimum alveolar concentration (MAC) of sevoflurane every 10 min using Anesthetic Consumption = Flow Rate × Concentration of Anesthetic in Vapor.
Time frame: Intraoperatively
Diaphragmatic excursion
Diaphragmatic excursion will be recorded using ultrasound preoperatively and postoperatively.
Time frame: 24 hours postoperatively
Time to the first request for the rescue analgesia
Time to the first request for the rescue analgesia will be recorded from the end of surgery till first dose of meperidine administrated.
Time frame: 24 hours postoperatively
Incidence of complications
Incidence of complications such as local anesthetic systemic toxicity (LAST), bradycardia, hypotension, nausea, vomiting, and respiratory depression will be recorded.
Time frame: 24 hours postoperatively
Recovery profile
Recovery profile will be recorded using Richmond Agitation and Sedation Scale (RASS) was required to be between - 3 and + 4 for a delirium classification (ISMV 4 only; RASS not collected in ISMV 3.
