Erector Spinae Plane Block for Acute Pain Management in the Emergency Department

Rib fractures are a common cause of respiratory distress in trauma patients as poor pain control and subsequent hypoventilation commonly results in lung tissue collapse (atelectasis). The current mainstay of treatment in rib fractures are oral and intravenous opioids however these are often ineffective and can also precipitate hypoventilation. Recently there has been interest in regional anaesthesia techniques for managing painful conditions of the thorax as a way to avoid pain and opioid related hypoventilation. These techniques include ultrasound guided nerve blocks such as the intercostal, paravertebral and serratus anterior blocks. The use of these techniques is however limited by minimal dermatomal coverage as well as a high incidence of complications The erector spinae plane block is a new, very promising technique which offers a safe means of providing anaesthesia to a large part of the hemithorax with a single injection. The proposed study will seek to establish whether the erector spinae plane block can be successfully used in the emergency department for pain control in patients with acute rib fractures.
