About

A prospective cohort study comparing PENG block versus iliac fascia block with the aim of evaluating its effectiveness in the peri-surgical analgesia of intracapsular femoral fracture.

Full description

Hip fractures are a very common clinical situation in elderly patients and are associated with significant morbidity and mortality. In addition, they have a great social and economic impact that in most cases requires definitive surgical treatment.

Although it is a very common procedure, in proximal femur surgery there is great variability with respect to anesthetic procedures and their subsequent management. Subarachnoid anesthesia is the most commonly used for this type of surgery. During the last few years, different locoregional techniques have been described with the aim of improving perioperative analgesia in these patients. Some examples are the iliac fascia block, the 3-in-1 block or the femoral nerve block, which allow a lower consumption of opioids and reduce some adverse effects such as postoperative delirium.

The PENG (Pericapsular Nerve Group) block is a block recently described for pain management in proximal femoral surgery. It is a pure sensory block that was initially described as an analgesic technique for the treatment of acute pain after femoral fracture but has expanded its uses. Its target corresponds precisely to the described innervation of the anterior femoral capsule.

Regarding the other locoregional techniques mentioned above, these consist of non-selective blocks of the femoral, lateral femoral cutaneous and obturator nerves. Therefore, although the iliac fascia block is accepted for analgesic control of hip fracture, the PENG block is likely to be more effective because of its high selectivity.

For this reason, the investigators have decided to conduct a prospective cohort study comparing PENG block versus iliac fascia block with the aim of evaluating its effectiveness in the peri-surgical analgesia of intracapsular femoral fracture.

Trial design

88 participants in 2 patient groups

PENG block

Description:

To perform the PENG block, the patient will be placed in the supine position and with the convex transducer in a transverse plane over the anteroinferior iliac spine, the probe will be aligned with the iliopectineal eminence of the pubic ramus rotating about 45º medially.

Treatment:

Procedure: Surgical treatment of femur fracture

Fascia iliaca compartment block

Description:

To perform the iliac fascia block, the patient is placed in the supine position and with the linear transducer placed at the junction of the middle third with the lateral third of the inguinal ligament, the needle is inserted through the fascia lata and the iliac fascia.

Treatment:

Procedure: Surgical treatment of femur fracture
