Postmortem concentrations of ropivacaine, bupivacaine, and lidocaine in femoral venous blood after hip fracture surgery.

ABSTRACT: Pain relief in hip fracture patients may be sought by injecting local anesthetic such as ropivacaine, bupivacaine, and lidocaine to the femoral area. As femoral veins are a routine sampling site for postmortem blood, this short report aimed to describe the levels of local anesthetics in ipsilateral (i.e., side of surgery) and contralateral (i.e., opposite side) femoral blood in ten medico-legal autopsy cases that had undergone a hip fracture surgery within 7 days before death. Postmortem blood samples were systematically collected from the ipsilateral and contralateral femoral veins, and toxicological analysis was performed in an accredited laboratory. The sample comprised six female and four male decedents who died at the age of 71-96 years. Median postoperative survival was 0 days and me
