The obturator nerve block has been shown to be a useful procedure in many clinical settings. The use of ultrasound has made this technique easier and safer to perform. It is important to know the anatomical landmarks and more espe-cially the expected motor endpoints when using a stimulating needle, so the ultrasound technique, where difficult, can ...

Japanese Clinical Medicine, 2011 Both obturator and sciatic nerve block in combination with femoral nerve block (FNB) have been suggested to be useful in relieving pain after total knee arthroplasty (TKA), compared with FNB alone.

Obturator and genitofemoral nerve blocks
Techniques in Regional Anesthesia and Pain Management, 1999The obturator and genitofemoral nerves supply sensory and motor innervation to the relatively large area of the inguinal region, thigh, hip, and knee joints. These nerves are situate in relatively easily accessible anatomic positions. Their wide innervation and easy accessibility make blocks of obturator and genitofemoral nerves useful in many clinical

Sonographic Imaging of the Obturator Nerve for Regional Block
Regional Anesthesia and Pain Medicine, 2007Today, there is a growing appreciation of the importance of the obturator nerve in clinical anesthesia. The aim of this study is to describe the ultrasound appearance of the obturator nerve for potential utility in guiding these nerve blocks.We scanned left and right inguinal regions of 20 volunteers lateral and distal to the pubic tubercle (PT) and ...

Adding a Selective Obturator Nerve Block to the Parasacral Sciatic Nerve Block: An Evaluation
Anesthesia & Analgesia, 2004Our aim was to objectively evaluate the efficacy of obturator nerve anesthesia after a parasacral block. Patients scheduled for knee surgery had a baseline adductor strength evaluation. After a parasacral block with 30 mL 0.75% ropivacaine, sensory deficit in the sciatic distribution (temperature discrimination) and adductor strength were assessed at 5-

Obturator nerve block is commonly used for transurethral resections of the bladder in order to inhibit reflectory adductor muscle reaction during electrocoagulation and to reduce the risk of bladder wall perforation during transurethral surgery. Furthermore, obturator block is used to complete regional blocks for major knee surgery in addition to ...

During transurethral electroresection in the posterolateral bladder neck, trigone and posterior urethra, unintentional contractions of the thigh-adductor muscles may occur due to irritation of the obturator nerve. The sudden displacement of the bladder wall against the cutting loop may cause a perforation of the bladder.

Ultrasound-Guided Obturator Nerve Block
Regional Anesthesia and Pain Medicine, 2009For knee surgery, obturator nerve block (ONB) has been shown to enhance postoperative analgesia provided by femoral block. Current techniques for obturator block use surface landmarks or ultrasound guidance (USG) with nerve stimulation. This preliminary observational study evaluated the success of an ultrasound-guided ONB without the additional use of ...

An Evaluation of the Cutaneous Distribution After Obturator Nerve Block
Anesthesia & Analgesia, 2002In 1973, Winnie et al. introduced the inguinal paravascular three-in-one block, which allegedly provides anesthesia of three nerves--the femoral, lateral cutaneous femoral, and obturator nerves--with a single injection. This concept was undisputed until the success of the obturator nerve block was reassessed by using evidence of adductor weakness ...

The parasacral sciatic nerve block does not induce anesthesia of the obturator nerve
Journal of Anesthesia, 2012The ability of the parasacral sciatic nerve block (PSNB) to induce anesthesia of the obturator nerve remains controversial. Our objective was to evaluate the anesthesia of the obturator nerve after a PSNB.Forty patients scheduled to undergo knee surgery (anterior cruciate ligament reconstruction) were included in this prospective, randomized ...
