Sufentanil in Patients With Lower Extremity Fracture Surgery Myocardial Damage Function Study

This study explored the important role of BMP6/SMAD pathway in myocardial/injury protection by observing the effects of different doses of opioids on myocardial injury indexes hs-cTnI and BMP-6 related indexes in patients undergoing lower extremity fracture surgery, as well as the changes of BMP6 expression in bone marrow tissue of fracture end. The relationship between different doses of opioids and BMP6 and cardiac adverse events provides a theoretical basis for clinical rational drug use.
