简要总结
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.
详细描述
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.

结局指标
主要结局
change in numerical pain scale
时间窗: 24 hours after placement of sciatic catheter
Numerical Pain Scale (END) self-assessed by the patient before and after 24 hours of continuous analgesic block of the sciatic nerve, with infusion of levobupivacaine 0,125% or ropivacaine 0,2%. The scale score is 0-10 (0= no pain; 10 = pain as bad as can be)
次要结局
- change in numerical pain scale(72 hours after placement of sciatic catheter)
- classification of technique difficulties(72 hours after placement of sciatic catheter)
- classifications of possible complications(72 hours after placement of sciatic catheter)
