Fused real-time ultrasound and magnetic resonance imaging (MRI) may be used to improve the accuracy of advanced image guided procedures. However, its use in regional anesthesia is practically nonexistent. In this randomized controlled crossover trial, we aim to explore effectiveness, procedure-related outcomes, injectate spread analyzed by MRI, and safety of ultrasound/MRI fusion versus ultraso...

Femur fractures typically affect elderly patients with multiple co-morbidities. Pain control can be difficult, requiring intensive nursing and physician care as elderly patients may manifest cardiovascular and respiratory complications from opiate administration. Ultrasound (US)-guided three-in-one (3-in-1) femoral nerve block (FNB) is an option for pain management in patients with femur fractu...

Case A well nourished 43-year-old female presented with intestinal obstruction and a tender irreducible left femoral hernia. A viable loop of ileum was released from the hernia via a low inguinal approach and the small bowel proximal and distal were carefully examined. The femoral hernia was repaired and the patient made a slow but steady recovery, being discharged on the sixth postoperative da...

Objective: We previously found that intravenous succinylcholine, a depolarizing neuromuscular nicotinic receptors blocker, prevents bladder contractions induced by new neuronal pathways established by nerve transfer in decentralized dogs. We studied the detrusor pressure response in vivo and contractile response of bladder smooth muscle strips in vitro from sham, decentralized and reinnervated ...

Chronic groin pain in athletes is often difficult to diagnose and treat. There are many anatomic structures in the inguinal and groin region that have the potential to cause pain. We report 32 cases of a previously undescribed condition in athletes of "obturator neuropathy," a fascial entrapment of the obturator nerve where it enters the thigh. This condition represents a type of groin pain in ...

INTRODUCTION Pelvic Schwannoma is an extremely rare event. Laparoscopic approach for radical resection on pelvic region already has been described in the literature. However, with better image quality provided by optic in the laparoscopy we can assure an improvement in this kind of approach for tumor resection. OBJECTIVE Our goal is to describe and evaluate the results of one laparoscopic res...

Background and Aims: This double blind prospective randomized clinical trial evaluated the efficacy and safety of continuous ultrasound-guided lumbar plexus block compared to continuous ultrasound-guided femoral nerve block, in the intra-operative and postoperative periods after total knee replacement. Methods: Forty ASA I-III patients were randomized to receive: continuous femoral block (n= 20...
