Abstract
Background:
Peripheral nerve blocks are commonly used as sole anesthetic for surgical
procedure However, insufficient nerve block is an important factor for decreased
patient satisfaction
Therefore, early detection of block failure would allow application of rescue
techniques in the proper time which improve patient satisfaction and save time in
the operating theater
Methods : A prospective observational study was conducted in Cairo University
Hospital, We included consecutive adult (18-65 years) patients, scheduled for
elective upper limb procedure under ultrasound-guided supraclavicular blockelective upper limb procedure under ultrasound-guided supraclavicular block.
Result : We evaluated the ability the thermal imaging to detect the success of SCB
at different nerve segments and found that it can accurately detect patients with
successful block. Our results showed excellent negative predictive value for
thermal imaging at 10 min in block failure (98-100%) while its positive predictive
value was low.
