Ultrasound‐guided combined pectoral nerve block and axillary venipuncture for the implantation of cardiac implantable electronic devices

Efficacy and safety of supraclavicular and pectoralis nerve blocks as primary peri-procedural analgesia for cardiac electronic device implantation: A pilot study

BACKGROUND

Cardiac implantable electronic devices (CIEDs) are routinely implanted using intravenous drugs for sedation. However, some patients are poor candidates for intravenous sedation.

OBJECTIVE

We present a case series demonstrating the safety and efficacy of a novel, ultrasound-guided nerve block technique that allows for pre-pectoral CIED implantation. The targets are the supraclavicular nerve (SCN) and pectoral nerve (PECS1).

METHODS

We enrolled 20 patients who were planned for new CIED implantation. Following US-localization of the SCN and PECS1, local anesthetic (LA) was instilled at least 30-60 min pre-procedure. Successful nerve block was determined if < 5 mL of intraprocedural LA was used, along with lack of sensation with skin and deep tissue pinprick. Optional sedation was offered to patients' pre-procedure if discomfort was reported.

RESULTS

Seventeen patients (85%) had a successful periprocedural nerve block, with only three patients exceeding 5 mL of LA. SCN and PECS1 success occurred in 19 (95%) and 18 (90%) patients, respectively. The overall success of nerve block by fulfilling all the criteria was demonstrated in 17 out of 20 patients (85%). Patients who reported no pain (VAS score = 0) were distributed as follows: 13 patients (65%) in the immediate post-procedure interval, 18 patients (90%) at the 1 h post-implant interval, and 14 patients (70%) at the 24 h post- implant interval. The median cumulative VAS score was 0 (IQR = 0 - 1). There were no reported significant adverse effects.

CONCLUSION

SCN and PECS1 nerve blocks are safe and effective for patients undergoing CIED implantation to minimize or eliminate the use of intravenous sedation.

Ultrasound utilization for implantation of cardiac implantable electronic devices

Ultrasound (US) guidance for implantation of cardiac implantable electronic devices (CIED) is currently not routine practice. This article sought to review published data on the use of ultrasound in each of the major surgical steps involved in implantation of CIEDs, including achieving anesthesia, obtaining venous access and implantation of leads. A literature review was performed, revealing a total of 20 peer-reviewed studies that assessed US guidance for CIED implantation; 3 of these were randomized trials while the remainder were mostly feasibility studies. The available data suggest that ultrasound can be useful in guiding implantation of CIEDs, with a trend towards less complication rates; however, more high-quality studies that compare US guidance to traditional techniques in CIED implantation are required.

Chest Wall and Abdominal Blocks for Thoracic and Abdominal Surgeries: A Review

PURPOSE OF REVIEW

The purpose of this review is to provide an up-to-date description and overview of the rapidly growing literature pertaining to techniques and clinical applications of chest wall and abdominal fascial plane blocks in managing perioperative pain.

RECENT FINDINGS

Clinical evidence suggests that regional anesthesia blocks, including fascial plane blocks, such as pectoralis, serratus, erector spinae, transversus abdominis, and quadratus lumborum blocks, are effective in providing analgesia for various surgical procedures and have more desirable side effect profile when compared to traditional neuraxial techniques. They offer advantages such as reduced opioid consumption, improved pain control, and decreased opioid-related side effects. Further research is needed to establish optimal techniques and indications for these blocks. Presently, they are a vital instrument in a gamut of multimodal analgesia options, especially when there are contraindications to neuraxial or para-neuraxial procedures. Ultimately, clinical judgment and provider skill set determine which blocks-alone or in combination-should be offered to any patient.

Ultrasound-guided access to the axillary vein for implantation of cardiac implantable electronic devices: A systematic review and meta-analysis

The aims of our systematic review were to quantify the expected rate of procedural success, early and late complications during CIED implantation using US-guided puncture of the axillary vein and to perform a meta-analysis of those studies that compared the US technique (intervention) versus conventional techniques (control) in terms of complication rates. MEDLINE, ISI Web of Science, and EMBASE were searched for eligible studies. Pooled Odds Ratio (OR) and Pooled Mean Difference (PMD) for each predictor were calculated. The quality of evidence (QOE) was evaluated according to the GRADE guidelines. Thirteen studies were included a total of 2073 patients. The overall success of US-guided venipuncture for CIED implantation was 96.8%. As regards early complications, pneumothorax occurred in 0.19%, arterial puncture in 0.63%, and severe hematoma/bleeding requiring intervention in 1.1%. No cases of hemothorax, brachial plexus, or phrenic nerve injury were reported. As regards late complications, the incidence of pocket infection, venous thromboembolism, and leads dislodgement was respectively 0.4%, 0.8%, and 1.2%. In the meta-analysis (five studies), the intervention group (US-guided venipuncture) had a trend versus a lower likelihood of having a pneumothorax (0.19% vs 0.75%, p = 0.21), pocket hematoma (0.8% vs 1.7%, p = 0.32), infection (0.28% vs 1.05%, p = 0.29) than the control group, but this did not reach statistical significance. The overall QOE was low or very low. In conclusions we found that the US-guided axillary venipuncture for CIEDs implantation was associated with a low incidence of early and late complications and a steep learning curve.

A Novel Nerve Block Technique for a Patient Undergoing Cardiac Device Implantation

A woman with type 1 myotonic dystrophy received an implantable cardioverter-defibrillator using a novel combination of ultrasound-guided supraclavicular nerve and pectoral nerve blocks. The entire procedure was completed without any procedural sedation or local anesthetic, and the patient did not experience any pain during or after the procedure. (Level of Difficulty: Advanced.).

EHRA expert consensus statement and practical guide on optimal implantation technique for conventional pacemakers and implantable cardioverter-defibrillators: endorsed by the Heart Rhythm Society (HRS), the Asia Pacific Heart Rhythm Society (APHRS), and the Latin-American Heart Rhythm Society (LAHRS)

With the global increase in device implantations, there is a growing need to train physicians to implant pacemakers and implantable cardioverter-defibrillators. Although there are international recommendations for device indications and programming, there is no consensus to date regarding implantation technique. This document is founded on a systematic literature search and review, and on consensus from an international task force. It aims to fill the gap by setting standards for device implantation.

Ultrasound guided percutaneous cephalic venipuncture for implantation of cardiac implantable electronic devices

BACKGROUND

Preoperative ultrasound (US) for cephalic cut-down is related to shorter procedure time and higher success rate. This study aimed to assess efficiency of US-guided percutaneous cephalic vein (CV) puncture for placement of cardiac implantable electronic devices (CIEDs).

METHODS

Patients undergoing a procedure including both US-guided pectoral nerve block (PECS) and percutaneous CV puncture were retrospectively investigated. Patient medical history and demographic data was collected. Clinical features of the procedures and intra- and post-operative complications occurring were collected from patient records. Clinical data included target vessel features, and the time taken for the following: CV puncture; CV and PECS puncture; total procedure.

RESULTS

In total 34 patients had CV puncture with US-guided PECS block was attempted in all patients and the procedure was successful in 27 of 34 (79.4%) patients. The total number of CV puncture attempts was 62 for 34 leads (mean attempts per lead = 1.82). The mean ± standard deviation time for CV puncture was 137.5 ± 27.4 s. There were no venous access-related complications.

CONCLUSION

US-guided CV puncture appears feasible and safe with an acceptable success rate. In case of failure of the US-guided axillary or subclavian vein approach, it may be preferred as an alternative to the cephalic cut-down procedure, where the success rate is relatively lower and the risk of bleeding is higher.
