Comparative Analysis of Three Locoregional Anesthesia Methods in Breast Tumour Pathology Surgery

"Interfascial blocks emerged as locoregional techniques that incorporate ultrasonography to visualise the anatomy while administrating the drug, reducing the rate of complications. There are multiple locoregional interfascial techniques continue to be implemented; in 2011 Blanco described Pectoral Nerve Block (PECS block); in 2012, Serratus-Intercostal Fascial Plane Block (SIFP) was described, and in 2016, Forero described the Erector Spinae Plane Block (ESP).~Drug: 30 cc 0.25% bupivacaine. Nerves blocked by SIFP block: lateral and anterior cutaneous branches of the 2nd-6th Intercostal Nerves.~Devices: S-Nerve® ultrasound was used in all three techniques; linear 6 to 13 Megahertz and convex 2 to 5 Megahertz transducers and 22G (Gauge) x 50 mm needles."
