Prediction of blood pressure change during surgical incision under opioid analgesia using sympathetic response evoking threshold
Abstract Opioid inhibition of nociceptive stimuli varies in individuals and is difficult to titrate. We have reported the vascular stiffness value (K) as a standard monitor to quantify sympathetic response with high accuracy. On the contrary, among individuals, a considerable variation in the rate o...
