Study Summary

The investigators are proposing to continue investigation to improve the accuracy of the SpHb (continuous hemoglobin monitoring device) by administering an intermediate acting digital nerve block in the finger connected to the SpHb, specifically bupivacaine 0.25% in patients undergoing spine surgery. Bupivacaine is FDA approved and in routine use.

Primary Outcome

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.

Interventions

  • OTHER intermediate-acting digital nerve block
