A Novel Single-puncture Triple Nerve Block; Sciatic, Obturator, Femoral Technique (SOFT), as a Sole Anesthesia for Knee Surgeries

2016-11-02 07:53:22 | BioPortfolio


This study aims to describe and to evaluate the effectiveness (success rate) of a supine ultrasound (US) guided single-puncture sciatic, obturator and femoral neve block technique (SOFT block) in knee surgery.


Under aseptic technique, all the patients will receive US-guided femoral, obturator and sciatic nerve blocks using a single puncture point. All blocks will be performed by an expert anesthetist. The femoral nerve will be blocked lateral to the femoral artery. The obturator nerve will be blocked after it exits the obturator canal (deep to pectineus muscle). While the sciatic nerve will be blocked deep (posterior) to the inferior border of quadratus femoris muscle. The motor block of the femoral, obturator and sciatic nerves and sensory block of the lateral femoral cutaneous nerve (LFCN) will be assessed before shifting the patient to the operating room.

The performance time, patient discomfort, technique success rate, the associated successful LFCN block and any complication will be recorded by the assistant. All patients were assessed neurologically before discharge and during the physiotherapy visits for 3 weak after surgery.

Medical and Biotech [MESH] Definitions

Interruption of sympathetic pathways, by local injection of an anesthetic agent, at any of four levels: peripheral nerve block, sympathetic ganglion block, extradural block, and subarachnoid block.

Noninflammatory degenerative disease of the knee joint consisting of three large categories: conditions that block normal synchronous movement, conditions that produce abnormal pathways of motion, and conditions that cause stress concentration resulting in changes to articular cartilage. (Crenshaw, Campbell's Operative Orthopaedics, 8th ed, p2019)

Mechanical compression of nerves or nerve roots from internal or external causes. These may result in a conduction block to nerve impulses (due to MYELIN SHEATH dysfunction) or axonal loss. The nerve and nerve sheath injuries may be caused by ISCHEMIA; INFLAMMATION; or a direct mechanical effect.

An instrument used to assess the results of rehabilitation from knee injuries, especially those requiring ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION. It measures recovery of knee joint function based on ACTIVITIES OF DAILY LIVING.

A local anesthetic of the ester type that has a slow onset and a short duration of action. It is mainly used for infiltration anesthesia, peripheral nerve block, and spinal block. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1016).
