Introduction: Peripheral nerve blocks (also known as regional anaesthesia) are currently used by many anaesthesiologists and emergency physicians for perioperative and procedural pain management. Methods: This is a cross sectional descriptive study conducted to evaluate knowledge, attitudes, and current practice towards use of peripheral nerve blocks for lower extremity injuries at Black Lion Hospital, a tertiary trauma centre in Addis Ababa. Results: A standardised survey was conducted with 64 participants working in emergency medicine [30/64 (46.9%)] and orthopaedics [34/64 (53.1%)]. Twenty-three of 64 (35.9%) respondents had received formal training. Knowledge was acquired from didactic/workshop format for 15/23 (65.2%), followed by peer training 6/23 (39.1%). The majority, 62/64 (96.9%), believed that knowledge of general anatomy and nerve blocks are very important. Thirty-one of 64 (48%) of the respondents did not routinely perform peripheral nerve blocks. A majority, 27/31 (87.1%) stated they lacked the required skills. Ultrasound guidance of the femoral nerve 16/33 (48.5%) was the most commonly performed peripheral nerve block, followed by ankle block using anatomic landmarks 15/33 (45.5%). Almost all (15/16) ultrasound-guided nerve blocks were done by emergency medicine providers, while all anatomic land mark guided blocks were done by orthopaedic teams. A majority of the respondents (93.8%) (n = 60) were optimistic that their practice on peripheral nerve blocks would increase in future. A highly significant association was found between previous training on peripheral nerve blocks and the number of peripheral nerve blocks performed in a month; p value – 0.006. Discussion: This study indicates peripheral nerve blocks are likely underutilised due to lack of training. There was a positive attitude towards peripheral nerve blocks but gaps on knowledge and practice.
