Prospective Comparison of Continuous Femoral Nerve Block with Nonstimulating Catheter Placement Versus Stimulating Catheter-Guided Perineural Placement in Volunteers

Schmerztherapie mit Stimulationskathetern bei Kniegelenkersatz

“…Neue technische Entwicklungen wie ultraschallgezielte Katheterplatzierungen und Stimulationskatheter haben die Präzision dieser Techniken sehr verbessert und liefern auch die Mög-lichkeit der Kontrolle und Dokumentation der korrekten Katheterlage [8, 22,24]. Bei Stimulationskathetern wird zunächst eine Hohlnadel mit elektrisch leitender Spitze und isoliertem Schaft in üblicher Technik nervennah platziert.…”

Minimal threshold for stimulating catheters

“…The surgery was uneventful. In the recovery room approximately three hours later and after the spinal block had worn off (as evidenced by the regression of both sensory and motor block), a continuous femoral nerve catheter was inserted into the patient according to previously described landmarks [4]. Using a Pajunk Stimulong Plus stimulating catheter kit (Pajunk GmbH, Geisingen, Germany) and a B Braun Stimuplex HNS-11 neurostimulator (B Braun, Melsungen, Germany) set at a pulse width of 0.1 ms and a frequency of 2 Hz, quadriceps twitches were elicited at a minimal threshold of 0.5 mA with the needle; the catheter was then threaded 5 cm while maintaining the same motor response at the same minimal threshold.…”

Continuous peripheral nerve blocks: state of the art

“…This procedure may improve the success rate of proper catheter positioning, when a stimulating catheter is used. A prospective study [7 ] analyzed if catheter placement with the help of a stimulating catheter [8] may increase the success rate and quality of continuous femoral nerve blockade. The authors showed that stimulating catheter placement increased significantly the percentage of block success (100% versus 85% in a control group) and that the patients' tolerance to electrical stimulation and depth of motor block was significantly higher with these catheters, resulting in improved placement closer to the nerve.…”
