Chronic pelvic pain is a disabling condition that affects a large number of men and women. It may occur after a known inciting event, or it could be idiopathic. A common cause of pelvic pain syndrome is neuropathy of the pelvic nerves, including the femoral and genitofemoral nerves, ilioinguinal and iliohypogastric nerves, pudendal nerve, obturator nerve, lateral and posterior femoral cutaneous nerves, inferior cluneal nerves, inferior rectal nerve, sciatic nerve, superior gluteal nerve, and the spinal nerve roots...

INTRODUCTION: Atherosclerosis has a complex etiology that leads to arterial obstruction and often results in inadequate perfusion of the distal limbs. Patients with atherosclerosis can have severe complications of this condition, with widespread systemic manifestations, and the operations undertaken are often challenging for anesthesiologists. CASE REPORT: A 79-year-old woman with chronic heart failure and respiratory dysfunction presented with bilateral gangrene of the distal lower extremities with obstruction of the left common iliac artery due to atherosclerosis...

UNLABELLED: Research suggests that the addition of dexmedetomidine to local anesthetics can prolong peripheral nerve blocks; however, it is not known whether dexmedetomidine can reduce the quantity of local anesthetic needed. We hypothesized that adding dexmedetomidine as an adjuvant to an obturator nerve block could reduce the median effective concentration of lidocaine. In this double-blinded randomized trial, 60 patients scheduled for elective transurethral resection of bladder tumors on the lateral wall were randomly divided into two groups: the control group (C group, n = 30) and the dexmedetomidine group (D group, n = 30)...

OBJECTIVES: Obturator nerve block is recommended to prevent obturator nerve reflex during transurethral resection. However, alternate techniques have been developed. The aim of the present study was to examine outcomes of interadductor approach. METHODS: After obtaining approval from the ethics committee, files of patients who underwent transurethral resection surgery between October 2013 and October 2014 were reviewed. RESULTS: A total of 137 transurethral resection patients were identified, in 69 (2 women, 67 men) of whom a combination of spinal anesthesia and obturator nerve block was used...

BACKGROUND AND OBJECTIVES: Total knee arthroplasty (TKA) is associated with severe pain, and effective analgesia is essential for the quality of postoperative care and ambulation. The analgesic effects of adding an obturator nerve block (ONB) to a femoral triangle block (FTB) after TKA have not been tested previously. We hypothesized that combined ONB and FTB will reduce opioid consumption and pain compared with those of a single FTB or local infiltration analgesia (LIA). METHODS: Seventy-eight patients were randomized to combined ONB and FTB, single FTB, or LIA after primary unilateral TKA...

BACKGROUND AND OBJECTIVES: Adductor canal block contributes to analgesia after total knee arthroplasty. However, controversy exists regarding the target nerves and the ideal site of local anesthetic administration. The aim of this cadaveric study was to identify the trajectory of all nerves that course in the adductor canal from their origin to their termination and describe their relative contributions to the innervation of the knee joint. METHODS: After research ethics board approval, 20 cadaveric lower limbs were examined using standard dissection technique...

AIM: The purpose of this study was to report our experience with peripheral nerve blockade in pediatric and young adult patients with skeletal dysplasia undergoing knee arthroscopy. BACKGROUND: The incidence of skeletal dysplasia is 1:4000 live births. These patients have biomechanical predispositions to knee joint degeneration, which is often palliated by arthroscopic surgery. Regional anesthesia has been proven to improve the cost and quality of care in adults undergoing arthroscopic knee surgery...

We evaluated an alternative technique for ultrasound-guided proximal level obturator nerve block that might facilitate needle visualisation using in-plane ultrasound guidance. Twenty patients undergoing transurethral bladder tumour resection requiring an obturator nerve block were enrolled into a prospective observational study. With the patient in the lithotomy position, the transducer was placed on the medial thigh along the extended line of the inguinal crease, and aimed cephalad to view a thick fascia between the pectineus and obturator externus muscles that contains the obturator nerve...

INTRODUCTION: In this prospective randomized controlled study, we investigated the efficacy of obturator nerve block (ONB) on adductor muscle spasm and related short-term outcomes and complications in patients who underwent transurethral resection of lateral wall-located bladder tumours (TURBT). METHODS: Between July 2014 and February 2015, 70 patients scheduled to undergo TUR of lateral bladder wall tumours were enrolled in the study. All patients were preoperatively evaluated by cystoscopy and imaging tools and selected according to localized tumours on the lateral bladder wall...

The ACUSON Freestyle, the world's first wireless ultrasound system, was released in April 2014. We assessed its usefulness, using it for central venous cannulation, spinal anesthesia, brachial plexus or obturator nerve block, and for the surgery of metastatic liver cancer as well as the spine. Generally, we could use it smoothly in all situations. Comparing with the conventional ultrasound system, the machine is big, heavy, with many buttons to operate. The main problem with the conventional ultrasound system is the wire connecting probe and the main system, which can interfere with procedures...

STUDY OBJECTIVE: The femoral, lateral femoral cutaneous, and obturator nerves (ONs) can reportedly be blocked using a single-injection deep to the fascia iliaca (FI) at the level of the inguinal ligament. Two commonly used methods (the FI compartment and 3-in-1 blocks) have produced inconsistent results with respect to local anesthetic distribution and effect on the ON. To date, no study of either method has been performed using advanced imaging techniques to document both needle placement and local anesthetic distribution...

The knowledge of variant anatomy of medial compartment of thigh is extremely important in surgical procedures requiring obturator nerve block. The nerve block is also recommended for providing additional analgesia following major knee surgeries and for relieving painful adductor muscle spasm. The interfascial injection technique is commonly followed in ultrasound guided obturator nerve block. For this procedure it is imperative to identify the adductor muscles on sonography to inject the anesthetic solution in the intermuscular fascial planes...

Patients frequently suffer from lumbosacral plexus disorder. When conducting a neurological examination, it is essential to assess the extent of muscle paresis, sensory disorder distribution, pain occurrence, and blocked spine. An electromyography (EMG) can confirm axonal lesions and their severity and extent, root affliction (including dorsal branches), and disorders of motor and sensory fiber conduction. Imaging examination, particularly gadolinium magnetic resonance imaging (MRI) examination, ensues. Cerebrospinal fluid examination is of diagnostic importance with radiculopathy, neuroinfections, and for evidence of immunoglobulin synthesis...

The purpose of this study was to investigate the effects of blockade of the saphenous nerve and the posterior branch of the obturator nerve in addition to a standard analgesic regimen for patients discharged the same day after knee arthroscopy. The primary outcome was knee pain on flexion during the first 24 postoperative hours, calculated as area under the curve. We allocated 60 patients to ultrasound-guided nerve blocks with either ropivacaine or saline, 30 to each. The median (IQR [range]) pain score on knee flexion in the ropivacaine group 2...
