Clavipectoral fascial plane block for implantable cardioverter defibrillator implantation

PECS II block for cardiac implantable electronic device insertion: A pilot study

AIM

Some 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.

METHODS

PECS 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.

RESULTS

Of 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.

CONCLUSIONS

PECS 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.

Awake Single-Stage Bilateral Clavicle Surgeries Under Bilateral Clavipectoral Fascial Plane Blocks: A Case Report and Review of Literature

The clavicle is a frequently fractured bone with an infrequent bilateral occurrence. Regional anesthesia (RA) for clavicle surgeries is always challenging due to its complex innervation arising from the two plexuses (cervical and brachial). Various RA techniques described for clavicle surgeries include plexus blocks, fascial plane blocks, and truncal blocks. Plexus blocks are associated with undesirable effects, such as phrenic nerve blockade and paralysis of the entire upper limb, limiting their application for bilateral regional clavicle surgeries. The clavipectoral fascial plane block (CPB) is a novel, procedure-specific, phrenic-sparing, and motor-sparing RA technique that can provide anesthesia or analgesia for clavicle surgeries. The decision to use the CPB and/or other RA techniques may depend on the site of clavicle injury or variations in clavicular innervation. We report a case of single-stage bilateral clavicle surgery successfully managed with a bilateral CPB alone using ultrasound guidance and landmark guidance separately. The patient was kept awake and comfortable throughout the surgery. In conclusion, CPB can be an effective alternate RA technique in avoiding undesired side effects of more proximal techniques such as phrenic nerve involvement and motor blockade of upper limbs. Landmark-guided CPB can be an alternative with equianalgesic efficacy as of ultrasound-guided CPB in resource-poor or emergency settings.
