Adductor Canal BlockNCT05587166
Ultrasound-Guided Oblique Short-Axis Adductor Canal Block.
A study testing ultrasound guided adductor canal block in people with Adductor Canal Block, run by Cairo University.
Trial summary
The ideal pain management for knee surgery should provide excellent analgesia while minimizing opioid consumption and allowing early mobilization and rehabilitation. The use of the continuous technique in ACB allows the delivery of a larger quantity of local anaesthetic into the adductor canal than in the single-shot… Read more about this study

About this study
Official title: Ultrasound-Guided Oblique Short-Axis Adductor Canal Block: Can the Oblique Approach Facilitate Perineural Catheter Insertion: A Randomized Controlled Trial
The ideal pain management for knee surgery should provide excellent analgesia while minimizing opioid consumption and allowing early mobilization and rehabilitation.
The use of the continuous technique in ACB allows the delivery of a larger quantity of local anaesthetic into the adductor canal than in the single-shot technique.

The usual approach for ultrasound-guided ACB catheter insertion is through short-axis in-plane approach in which the ultrasound transducer is applied horizontally over the femoral artery and saphenous nerve. In this approach, the catheter is inserted through a 90-degree angulation with the nerve which might make the catheter insertion difficult.
In the new oblique position, the catheter will be inserted in a less than 90-degree angulation. This study speculates that decreasing the angle of catheter insertion will make catheter insertion easier and faster.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The ideal pain management for knee surgery should provide excellent analgesia while minimizing opioid consumption and allowing early mobilization and rehabilitation.
The use of the continuous technique in ACB allows the delivery of a larger quantity of local anaesthetic into the adductor canal than in the single-shot technique.
The usual approach for ultrasound-guided ACB catheter insertion is through short-axis in-plane approach in which the ultrasound transducer is applied horizontally over the femoral artery and saphenous nerve. In this approach, the catheter is inserted through a 90-degree angulation with the nerve which might make the catheter insertion difficult.
In the new oblique position, the catheter will be inserted in a less than 90-degree angulation. This study speculates that decreasing the angle of catheter insertion will make catheter insertion easier and faster.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
