Peripheral Nerve Block

Arrow® StimuCath® Stimulating cPNB Catheter

The Arrow StimuCath continuous peripheral nerve block catheter allows clinicians to objectively confirm accurate catheter tip placement through nerve stimulation, which can help improve secondary block success. The wire-reinforced catheter body and unique coil tip are visible under ultrasound, providing additional feedback on the catheter location to the clinician. Stimulating catheters have been shown to improve clinical outcomes;1 significantly decrease pain scores;2,3,4 and reduce rescue medication consumption,3,5,6 compared to non-stimulating catheters. The StimuCath continuous peripheral nerve block catheter has been clinically proven to be safe and effective for post-operative pain management.1,2,7,8,9

Peripheral Nerve Block Catheter Selection: Common Challenges & Solutions

Morin, et al recently published a semiquantitative systemic review of 11 studies comparing stimulating versus nonstimulating catheter techiques. In all nine of the trials that measured analagesic rescue treatment, the absolute reduction in rescue anesthetic was between 8% and 56% (8%, 15%, 19%, 28%, 32%, 33%, 38%, 49%, and 56%). The authors concluded that "Published reports of randomized controlled trials provide evidence for a better analgesic effect from stimulating catheters."5

A recent trial by Mariano, et al compared patients' pain scores after 24 hours for patients who received continuous peripheral nerve blocks using a nonstimulating catheter placed under ultrasound guidance and StimuCath placed using nerve stimulation. The study found that the average NRS patient pain scores on post operative day one were lower in the stimulating catheter group than the pain scores in the nonstimulating catheter, ultrasound only group (3.0 vs. 5.0; P=0.032)2.

StimuCath Detail of Wire

Arrow StimuCath in Blue Phantom ultrasound model using SonoSite® S-Nerve.

StimuCath's wire-reinforce catheter body and unique stainless steel coil tip are visible under ultrasound. The ability to visualize the catheter under ultrasound and confirm accurate catheter tip placement with nerve stimulation may help improve secondary block success.

StimuCath's wire-reinforced, flexible polyurethane catheter body is designed to minimize kinking, resulting in consistent delivery of anesthetic to the targeted nerve(s). The unique coil tip of the StimuCath catheter is designed to allow for an even distribution of anesthetic. If you need to change the position of the catheter during advancement, what is your current course of action? The specially designed StimuCath Tuohy needle allows for pull back and redirection of the catheter without withdrawing the needle and catheter and re-sticking the patient. This can save procedural time and reduce patient discomfort. (See IFU for complete instructions, including proper retraction techniques).

The proprietary StimuCath SnapLock catheter/syringe allows clinicians to perform a Raj test, confirming accurate catheter tip location after the needle and catheter stylet have been removed. The SnapLock adapter is attached to the proximal end of the StimuCath catheter and the SnapLock adapter is connected to the nerve stimulator. The nerve stimulator is turned up slowly until appropriate muscle contractions are elicited. Local anesthetic or normal saline is injected and the motor reaction immediately stops. This constitutes a positive Raj test, as further indication that the secondary block will be likely be successful.10

The StimuCath StatLock® catheter securement device was custom designed to securely hold the StimuCath catheter and SnapLock catheter/syringe connector to the patient. Additionally, the StimuCath Tuohy needle features a metal stylet to aid in subcutaneous tunneling of the catheter away from the catheter insertion site.
