    Efficacy of ultrasound-guided bilateral erector spinae plane block in pediatric laparoscopic cholecystectomy: Case series
    (2019) Karaca, Omer; Pinar, Huseyin Ulas; 0000-0003-0473-6763; 31741347; Q-2420-2015
    Postoperative opioid administration can cause various side effects, such as drowsiness, respiratory distress, postoperative nausea, and vomiting. The use of non-opioid medications as part of a multimodal analgesia method has been increasingly suggested in the management of acute postsurgical pain. Erector spinae plane block (ESPB), which is a regional anesthesia technique, blocks both visceral and somatic nerve fibers.Though it is infrequently used in young patients, presently described is a series of cases in which ESPB was successfully used in the performance of pediatric laparoscopic cholecystectomy. Ultrasound-guided bilateral ESPB was performed on 4 patients who underwent a laparoscopic cholecystectomy. An injection of 0.25% bupivacaine was administered into the interfascial area on each side in the pre-incisional period after the anesthesia induction (total anesthetic: 2.5 mg/kg). Postoperative pain control was planned at 10 mg/kg intravenous paracetamol every 8 hours. Numeric rating scale pain scores were less than 3 points in the post-anesthetic care unit, and at 1, 2, 4, 8, 12, and 24 hours. No rescue analgesic (1 mg/kg tramadol) was needed. None of the typical complications, such as drowsiness or nausea, were observed and no block-related complications were recorded. Bilateral ESPB that is a part of multimodal analgesia regimen can provide effective analgesia for pediatric laparoscopic cholecystectomy patients in the first 24 hours postoperatively.

    Ultrasound-Guided versus Conventional Caudal Block in Children: A Prospective Randomized Study
    (2019) Karaca, Omer; Pinar, Huseyin Ulas; Gokmen, Zeynel; Dogan, Rafi; 0000-0003-0473-6763; 0000-0003-1933-2075; 30602192; Q-2420-2015; AAU-6923-2020
    Background Injection to the accurate area without any complications is the main factor for the efficiencies of caudal block. The aim of this study was to compare success and the complications of conventional and ultrasound method for caudal block in children. Materials and Methods Two-hundred sixty-six American Society of Anesthesiologists (ASA) category 1 children aged between 6 months and 6 years undergoing hypospadias, circumcision, or both surgeries were randomly allocated two groups (Group C or Group H, n =133). About 0.25% bupivacaine with 1/200000 adrenaline (total volume: 0.5 mL/kg) was injected after the needle was inserted into the sacral canal in Group C, or right after the needle pierced the sacrococcygeal ligament under longitudinal ultrasound view in Group H. Success rate of block, block performing time, number of needle puncture, success at first puncture, complication rate, age and weight of the patients encountering these complications were recorded. Results The success rate of block was similar between two groups (94.7% in Group C vs 96.2% in Group U, p >0.05). Success at first puncture was higher in Group U than in Group C (90.2 vs 66.2%, respectively; p <0.001). Number of needle puncture, blood aspiration, subcutaneous bulging, and bone contact was higher in Group C but none in Group U ( p <0.001) and these complications were occurred in children weighing<16kg and less younger than 6 years old. Conclusion We observed that the complications were not encountered, number of needle puncture was lesser, and the success rate of first puncture was higher under ultrasound with longitudinal view.
