Continuous Femoral Block With Levobupivacaine 0.125% or Ropivacaine 0.2% in Elderly Patients With Femoral Fractures

Pain is associated with neurohormonal stress, myocardial ischemia and delayed mobilization, thus being able to increase the hospitalization time and associated with increased postoperative mortality. Regional anesthesia through simple or continuous femoral nerve block are options for analgesia in patients with femoral fracture, as well as analgesia by venous opioids. A potential benefit of regional anesthesia is precisely to avoid the use of opioids and other general anesthetics, which in turn are also closely related to postoperative delirium. Continuous femoral block, since the preoperative period, is associated with the reduction of acute pain and opioid consumption, in patients with femoral neck fractures. There are few studies available in the literature comparing analgesic equipotency between levobupivacaine and ropivacaine in peripheral nerve blocks. In none of them, the peripheral analgesia in the femoral nerve, for proximal femoral fracture was compared.
