ABSTRACT
BACKGROUND:
Variability in pain sensitivity is a well known phenomenon. The variability also extends to experimental stimuli and postoperative opioid requirement. But the report of the relationship between pain threshold and postoperative opioid requirement is very rare.METHODS:
We investigated prospectively the association between pressure pain threshold and postoperative morphine requirement. We estimated pressure pain threshold by using pressure algometer and adopted PCA to treat postoperative pain.RESULTS:
In this study the relationship between pain threshold and postoperative opioid requirement was significant. But the correlation was weak negative (Pearson r = -0.273, P < 0.05).CONCLUSIONS:
Considering other associated factors which affect postoperative pain, although correlation between pain threshold and postoperative opioid requirement was significant but we concluded that clinical relevance of pain threshold is uncertain.
