Ultrasound Guided Combined Peripheral Nerve Blocks in a High-Risk Patient: A Case Report

Abstract

The use of ultrasound in peripheral nerve blocks has become increasingly more frequent. Lower–extremity surgeries are mainly performed under general or central neuraxial anesthesia, ultrasound-guided combined peripheral nerve block (PNB) can be a good alternative anesthetic technique, especially for high-risk patients who require continuous anticoagulation treatment and present with poor cardiovascular conditions.
