Ultrasound-guided Retroclavicular Approach Versus Costoclavicular Approach of Infraclavicular Brachial Plexus Block for Upper Limb Surgeries.

BACKGROUND: Regional anesthesia for an upper limb provides many advantages over general anesthesia, especially in orthopedic surgery. OBJECTIVES: This trial aimed to compare a retroclavicular approach to the infraclavicular brachial plexus with a costoclavicular approach in term of needle time, image time, and procedure time, and comparing both with the classic technique for upper limb surgeries guided by ultrasound. STUDY DESIGN: Prospective, randomized, single-blinded controlled trial. SETTING: Minia University, Faculty of Medicine, Anesthesia and Intensive Care Department. METHODS: Sixty patients of both sees with an American Society of Anesthesiologists  Classification of I and II, a BMI (kg/m2) of 20-35, aged from 18-60 years who were scheduled for a forearm or hand surgery under infraclavicular brachial plexus block were divided into 3 parallel equal groups. Group I (RC) received a retroclavicular approach.  Group II (CC)received a costoclavicular approach.  Group III (CT) received the classic technique. Procedure time, the sum of the imaging and needling times, was our primary outcome. Secondary outcomes were the motor and sensory block success rate 30 minutes postinjection of local anesthesia, duration of motor and sensory block, Visual Analog Score, first analgesic need, total analgesia requirements during the first postoperative 24 hours, and any complications. RESULTS: The procedure and needle times were significantly decreased in the retroclavicular group due to better needle visibility. There was no significant difference regarding sensory and motor block data. The VAS score in the first postoperative 24 hours showed no statistical significance. Regarding analgesic data and patient satisfaction, there was no statistical significance among the 3 studied groups. There were no complications in any of the used approaches. LIMITATION: Our trial did not include patients with a BMI > 35. CONCLUSIONS: The retroclavicular approach is superior because of its decreased procedure time and needle time than both the costoclavicular approach and classic approach.

Ultrasound-guided Erector Spinae Muscle Block Versus Ultrasound-guided Caudal Block in Pediatric Patients Undergoing Lower Abdominal Surgeries.

BACKGROUND: The erector spinae plane block is a new regional anesthetic technique that is gaining popularity in pediatric medicine. OBJECTIVES: This study aimed to evaluate the safety and efficacy of ultrasound-guided erector spinae block and compare its analgesic effect with that of the ultrasound-guided caudal block in pediatric patients. STUDY DESIGN: Prospective, randomized, double-blind, controlled study. SETTING: Department of Anesthesia and Intensive Care, faculty of medicine, Minia University, Egypt. METHODS: Sixty-three children scheduled for unilateral lower abdominal surgeries, under general anesthesia were randomly allocated into 3 parallel equal groups: Group I (erector spinae block [ESB] group) received ultrasound-guided an erector spinae muscle block in a dose of 0.4 mg/kg of 0.25% bupivacaine between the 10th transverse process and the erector spinae muscles. Group II (caudal block [CB] group) received an ultrasound-guided caudal block in a dose of 2.5 mg/kg of 0.25% bupivacaine. The last group, Group III (control [C] group), did not receive any regional block. Our primary outcome was to evaluate the quality of postoperative analgesia using the Face, Legs, Activity, Cry, Consolability (FLACC) Pain Scale; secondary outcomes were to assess the time to first analgesic request, total analgesic requests during the first 24 hours, and the occurrence of any side effects. RESULTS: The early postoperative FLACC score was less in the ESB group than the CB group; both were lower than the control group. The erector spinae block had a longer duration of analgesia than the caudal block as the median (interquartile range [IQR]) ``of the duration of analgesia in the ESB group was 8 (8-12) hours while it was 6 (6-8) hours in group the CB group; both groups had a longer duration of analgesia compared to the C group 0.25 (0.17-4) hours. The total amount of analgesia was less in the ESB group than the CB group. The number of patients who needed rescue intravenous fentanyl analgesia was 14 patients in the C group while no patient needed intravenous fentanyl in the ESB and CB groups. LIMITATIONS: Sensory evaluation of the patients was not done since the 2 blocks were done under general anesthesia but did not affect the outcome. CONCLUSIONS: Ultrasound-guided erector spinae block was safe and effective in pediatric patients undergoing unilateral lower abdominal surgery as it provided a longer duration of analgesia and less analgesic requirement than caudal block and fewer side effects.
