Comparative Study Between Levobupivacaine and Ropivacaine in the Hip Fractures of the Elderly

Randomized and Controlled Phase IV Clinical Trial on the Analgesic Effectiveness of the Combined Blockade in the Hip Fractures of the Elderly: Comparative Study Between Levobupivacaine and Ropivacaine

Prospective, low-level, non-commercial intervention, comparative clinical trial (phase IV) of balanced, randomized groups, to compare the analgesic efficacy of the local anesthetics Ropivacaine and Levobupivacaine in peripheral nerve block in hip fracture surgery in the elderly .

There are several studies that try to identify the ideal anesthetic for the management and control of pain in hip fracture surgery in the elderly. The optimum would be to use an anesthetic with the lowest possible latency, since this will favor the start of surgery. And, at the same time, with a more lasting analgesia with the least motor impairment. Therefore, it is essential to collect data on efficacy (effective block that allows us to mobilize the patient), latency, and analgesic scales appropriate to the cognitive state of the study sample.

Inclusion Criteria:

• The patient will have to voluntarily sign and understand the informed consent that will be provided in writing.
• Patients over 65 years of age, with a hip fracture, who are going to be operated on at the Salamanca University Assistance Complex (CAUSA).

Exclusion Criteria:

• Rejection of the technique.
• Allergy to any of the drugs.
• Coagulation disorders.
• Local infections instead of puncture.
• Vascular prostheses at the femoral level.
