Open Reduction Internal Fixation (ORIF) – Finger

Anesthesia Implications

Position: Supine, arms at side on armboards, Bed turned 30 degrees
Time: 30-60 min (short)
Blood Loss: Very Low (5-10 ml)
Post-op Pain: Minimal (1-3)
Maintenance Paralytic: No
Lead: Yes
Tourniquet Use: Yes

Preference is to intubate to allow administration of paralytic. Hands are some of the first to move when the patient gets light, so paralytic is handy to ensure the patient remains motionless.

Fluoroscopy / Xray (general considerations): Have lead aprons and thyroid shields available. Alternatively, distancing yourself 3 to 6 feet will reduce scatter radiation to 0.1% to 0.025% respectively. Occupational maximum exposure to radiation should be limited to a maximum average of 20 Sv (joules per kilogram – otherwise known as the Sievert/Sv) per year over a 5 year period. Limits should never exceed 50 Sv in a single year.

Tourniquet (general considerations): Antibiotics should be administered prior to tourniquet inflation. Tourniquet pain usually begins 45-60 minutes after inflation and is unresponsive to regional anesthesia and analgesics. Upper extremity pressure should be set to approximately 70-90 mmHg above systolic blood pressure (SBP). Lower extremity tourniquet pressure should be set to approximately 2 times SBP. Upon tourniquet release, there will be increases in End-tidal CO2 and metabolic acidosis, while decreases will be seen in core body temperature, blood pressure, and mixed venous oxygen saturation (SvO2)
