研究概览
简要总结
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.
详细描述
Patients undergoing spine surgery will be randomized to receive (or not) the bupivacaine digital block on the finger attached to the new limited release version of the hemoglobin sensor, RevG. The SpHb reading will be compared to a blood hemoglobin level analyzed in the UCSF Clinical Laboratories.

结局指标
主要结局
SpHb (continuous hemoglobin monitor reading) minus tHb (clinical laboratory determined hemoglobin value).
时间窗: 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.
