Nerve Block Clinical Trial
Official title:
Erector Spinae Plane Block: Anatomical Landmark Versus Ultra-sounded Guided Technique, a Randomized Controlled Trial
The erector spinae plane (ESP) block is a technique that helps alleviate acute pain. It involves injecting local anesthetic between the erector spinae muscle (ESM) and the vertebra's transverse process (TP). This technique can be guided by ultrasound or anatomical landmarks, and it can be performed while the patient is lying down, sitting or on their side.
Ultrasound guidance has established itself as the norm for regional anesthesia procedures, enabling live visualization of anatomical structures and enhancing the precision and safety of needle insertion. Conversely, the blind technique relies on anatomical landmarks and the ability to palpate to direct needle insertion. Although the blind technique might provide simplicity and efficiency, uncertainties persist concerning its precision and possible associated risks. As the popularity of the ESPB increases, a relevant query emerges: Should it be conducted with ultrasound guidance or through a non-guided technique? This study was designed to validate the efficacy and safety of a landmark-guided ESPB technique compared to an ultrasound-guided ESPB technique for analgesia in breast surgery. The hypothesis was that the ultrasound and anatomical landmark techniques for ESPB would provide equivalent analgesia. The study's primary objective was to compare the success rate of both techniques. The secondary objectives were to compare the dermatomal block spread, analgesic effectiveness, and technique-related complications. ;
