Experimental: bupivacaine digital nerve block
Patients undergoing spine surgery will have a 50/50 chance of being randomized to receive a bupivacaine 0.25% (2 milliliters total) intermediate-acting digital nerve block.
Other: intermediate-acting digital nerve block
non-therapeutic Bupivacaine digital nerve block to assess effect on accuracy of diagnostic readings
No Intervention: No bupivacaine digital nerve block
Patients undergoing spine surgery will have a 50/50 chance of being randomized to not receive a bupivacaine 0.25% (2 milliliters total) intermediate-acting digital nerve block.
- SpHb (continuous hemoglobin monitor reading) minus tHb (clinical laboratory determined hemoglobin value). [ Time Frame: Intermittent (about hourly) hemoglobin checks throughout the surgery. ]
Use of a longer acting local anesthetic (bupivacaine) for the digital nerve block will result in SpHb (the non-invasive hemoglobin device) being sufficiently accurate for blood transfusion decisions(≤ 1.0 g/dL difference)
To assess if using an intermediate-acting digital nerve block will improve the accuracy of the SpHb readings when compared to a blood hemoglobin level analyzed in the UCSF Clinical Laboratories intermittently during the patient's surgery.
