About

This study evaluates the pain score numerical rating, after sciatic analgesic continuous block, in patients with ischemic pain before surgery of limb revascularization. All patients received those blocks to control ischemic severe pain.

Full description

Peripheral Obstructive Arterial Disease (PAD) is a disease with a prevalence of 10 to 25% in the population over 55 years, increasing with age, and may have disabling pain as a symptom, and sometimes the surgical approach is required. In the context of public hospital in Rio de Janeiro, where patients need to wait for surgery, the Anesthesiology and Acute Pain service routinely has sciatic nerve analgesic block in the popliteal region as a preoperative procedure.

The primary objective of the present study is to describe a series of cases where the technique was applied in order to relieve the pain of these patients, following the Pain Score Numerical rating as a reference. Secondary objectives will be to describe difficulties associated with the technique and possible associated adverse factors.

Enrollment: 15 patients
