Ultrasound-guided Ganglion Impar Block during the COVID-19 Pandemic: Two Case Reports

Abstract

Blocks of the ganglion impar are used to treat both malignant and benign causes of visceral and sympathetic pelvic and perineal pain. While conventionally done under fluoroscopic guidance, significant improvements in transducer technology in the past decade have piqued the interest and enthusiasm of interventional pain specialists toward ultrasound-guided performance. In the setting of a pandemic, it is important to ensure the efficacy of treatment as well as the safety of both patients and health care workers. This paper presents two patients who underwent two approaches of ultrasound-guided ganglion impar blocks in a tertiary government hospital in the Philippines during the COVID-19 pandemic.
