Intervention / Treatment |
---|---|
Experimental: Peripheral nerve block
Prospectively evaluate peripheral nerve blocks as a primary anesthetic in the setting of above-the-knee amputations. All enrollees will be administered Intravenous sedatives using propofol or dexmedetomidine and have ultrasound-guided femoral and sciatic nerve blocks placed per current practice at research site. Single-injection obturator nerve blocks and lateral femoral cutaneous nerve blocks will also be performed. |

Intravenous sedation using propofol or dexmedetomidine will be administered.
Other Names:
After administration of intravenous sedation, lateral femoral cutaneous and obturator nerve blocks (in addition to the femoral and sciatic catheters) will be performed under ultrasound guidance.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Chi-squared tests of peripheral nerve block success as a primary anesthetic
Time Frame: Changes from baseline through 30 days post-operative
|
Differences in block success percentages analyzed between study participants.
|
Changes from baseline through 30 days post-operative
|
Analysis of pain scores
Time Frame: Changes from baseline through 48 hours post procedure.
|
Numerical rating scale pain scores (0-10) will be obtained from patients upon arrival and recorded hourly until discharge.
Patients will be called or visited 24-48 hours post procedure to inquire about patient satisfaction.
Differences in study participant pain scores will be examined through t-tests.
P < 0.05 will be considered statistically significant.
