    AimSome truncal blocks could provide adequate surgical anesthesia and postoperative analgesia in cardiac implantable electronic devices (CIED) insertion. The aim of this study was to evaluate the feasibility of the pectoral nerves (PECS) II block for CIED insertion.MethodsPECS II blocks were performed on the left side using the ultrasound-guided single injection technique in all patients. The primary outcome for feasibility was the percentage of the cases completed without intraoperative additional local anesthesia. Secondary outcomes were the amount of intraoperative additional local anesthetic, intraoperative opioid requirement, postoperative pain scores, first requirement for postoperative analgesia, postoperative analgesic consumption, patient satisfaction, and block-related complications.ResultsOf the total 30 patients, 19 (63.3%) required intraoperative additional local anesthetic. The median (IQR [range]) volume of the additional local anesthetic used was 7 (4-10 [2.5-12]) mL. Two patients needed additional IV analgesics in the first 24 h postoperatively. No statistically significant differences were determined between the patients requiring and not requiring intraoperative additional local anesthetic in respect of age, gender, duration of surgery, block performance time, and hospital stay. A total of 26 (86.6%) patients reported a high level of satisfaction with the procedure.ConclusionsPECS II block for cardiac electronic implantable device insertion provides effective postoperative analgesia for at least 24 h. Although PECS II block alone could not provide complete surgical anesthesia in the majority of the patients, when combined with supplementary local anesthetic, contributes to a smooth intraoperative course for patients.

    Ultrasound-Guided External Oblique Intercostal Plane Block for Postoperative Analgesia in Laparoscopic Sleeve Gastrectomy: A Prospective, Randomized, Controlled, Patient and Observer-Blinded Study
    (Springer, 2024) Kavakli, Ali Sait; Sahin, Taylan; Koc, Umit; Karaveli, Arzu
    PurposeThe external oblique intercostal plane (EOI) block is a novel block technique for anterolateral upper abdominal wall analgesia. The superficial nature of the external oblique intercostal plane allows it to be easily identified even in patients with obesity. The aim of this study was to test the hypothesis that EOI block would reduce IV morphine consumption within 24 h after laparoscopic sleeve gastrectomy.Materials and MethodsPatients were randomly assigned to one of two groups: EOI block group and control group. The patients in the EOI block group received ultrasound-guided bilateral EOI block with a total of 40 ml 0.25% bupivacaine after anesthesia induction. The patients in the control group received no intervention. Postoperatively, all the patients were connected to an intravenous patient controlled analgesia (PCA) device containing morphine. The primary outcome of the study was IV morphine consumption in the first postoperative 24 h.ResultsThe median [interquartile range] morphine consumption at 24 h postoperatively was significantly lower in the EOI block group than in the control group (7.5 [3.5 to 8.5] mg vs 14 [12 to 20] mg, p = 0.0001, respectively). Numerical rating scale (NRS) scores at rest and during movement were lower in the EOI block group than in the control group at 2, 6, and 12 h but were similar at 24 h. No block-related complications were observed in any patients.ConclusionThe results of the current study demonstrated that bilateral EOI block reduced postoperative opioid consumption and postoperative pain in patients with obesity undergoing laparoscopic sleeve gastrectomy.Trial RegistrationClinicaltrials.gov identifier: NCT05663658.
