Ensuring the efficacy of a nerve block early in the perioperative period is critical, as delayed recognition of block failure may lead to intraoperative pain, the need for additional sedation or general anesthesia, and overall poorer patient outcomes. Conventional methods for assessing block success, such as sensory testing with pinprick or cold stimuli and motor assessment using strength scales, require patient cooperation and often take 15-30 minutes to yield definitive results. These delays are especially limiting in fast-paced surgical environments or when early decisions regarding anesthesia management are necessary.\n\nEmerging non-invasive monitoring technologies offer promising alternatives for the early, objective assessment of block efficacy. Infrared Thermography (IRT) measures skin surface temperature, which increases due to sympathetic nerve blockade-induced vasodilation.",[71,72],"Regional Anaesthsia","Brachial Plexus Blocks",[72,74],"Regional Anaesthesia","NOT_YET_RECRUITING","2025-07-22",{"date":78,"type":79},"2025-07-30","ACTUAL",{"date":81,"type":65},"2025-08-15",{"date":83,"type":65},"2026-09-01",{"name":5,"class":6}]
