Haematoma block versus sedation for manipulating distal radius fractures in the emergency department
When deciding between a haematoma block and sedation for distal radius manipulation, remember that procedural success rates appear comparable with no strong evidence favoring one over the other regarding major adverse events. If pain control is a primary concern, the literature points toward the haematoma block potentially offering less post-procedure discomfort. However, always weigh this against your ED's resource availability and institutional protocols.
This review compared using a haematoma block versus standard procedural sedation for manipulating distal radius fractures in adults presenting to the ED. The authors synthesized data from seven studies, including four randomized controlled trials, to assess both procedural success and adverse event rates between the two techniques. Overall, the evidence suggests that there is no consistent difference in achieving successful manipulation when comparing a haematoma block to sedation. While one study noted less reported pain following the haematoma block compared to sedation, other analyses did not find a statistically significant difference in overall adverse events between the groups. This suggests both approaches are viable alternatives for fracture reduction.
