Summary
The decision to transfuse or not to transfuse blood products is one of the main issues in
patients undergoing surgery.
The standard laboratory method of hemoglobin assessment is time-consuming, gives intermittent
data, and requires venipuncture which is invasive and painful. In the past decade, the use of
non-invasive and faster methods, which allow physicians to measure hemoglobin levels at the
patient's bedside, have become widespread. One of the tools that make this possible is
Spectrophotometric Hemoglobin.
However, one of the main concerns regarding this method is its accuracy. Since the accuracy
of this assessment depends on the extent of perfusion of the organ on which the probe is
placed, use of digital nerve blocks proposed to increase its accuracy.
This study aims to evaluate the effects of digital nerve block (with bupivacaine) on the
accuracy of non-invasive hemoglobin monitoring by spectrophotometry in patients undergoing
spinal surgery.
