Total hip arthroplasty (THA) is amenable to a variety of regional anaesthesia (RA) techniques that may improve patient outcome. We sought to answer whether RA decreased mortality, cardiovascular morbidity, deep venous thrombosis (DVT) and pulmonary embolism (PE), blood loss, duration of surgery, pain, opioid-related adverse effects, cognitive defects, and(More)
PURPOSE The purpose of this study is to determine if real time ultrasound guidance improves the success rate of axillary brachial plexus blockade. METHODS Patients undergoing elective hand surgery were randomly assigned to one of three groups. Axillary blocks were performed using three motor response endpoints in the nerve stimulator (NS) Group, real-time(More)
BACKGROUND Current techniques of brachial plexus block are "blind," and nerve localization can be frustrating and time consuming. Previous studies on ultrasound-assisted brachial plexus blocks are mostly performed with scanning probes of 10 MHz or less. The authors tested the usefulness of a state-of-the-art, high-resolution ultrasound probe (up to 12 MHz)(More)
OBJECTIVE Endothelial dysfunction and decreased nitric oxide bioavailability may explain why therapeutic angiogenesis and cell therapy have mostly failed in humans. Building from previous large animal work, the Phase I Endothelial Modulation in Angiogenic Therapy trial tested the hypothesis that L-arginine, a nitric oxide donor, may be safe and effective in(More)
Ultrasound guidance has led a surge of interest in transversus abdominis plane (TAP) block for postoperative analgesia following abdominal surgery. Despite or because of the numerous descriptive applications and techniques that have recently populated the literature, results of comparative studies for TAP block have been inconsistent. This systematic review(More)
STUDY OBJECTIVE To evaluate the validity and reliability of an objective scoring system, the Post-Anesthetic Discharge Scoring System (PADSS), which was compared against existing Clinical Discharge Criteria in the ambulatory surgery unit of our hospital. DESIGN randomized, open study. SETTING Ambulatory surgery unit at a university teaching hospital. (More)
BACKGROUND AND OBJECTIVES Compared with conventional fluoroscopic-guided pudendal nerve block, ultrasonography has potential advantages for visualizing anatomical landmarks such as the internal pudendal artery and nerve, the sacrospinous and sacrotuberous ligaments, and local anesthetic spread. We examined the clinical utility of performing pudendal nerve(More)
BACKGROUND Regional anesthesia (RA) provides excellent anesthesia and analgesia for many surgical procedures. Anesthesiologists and patients must understand the risks in addition to the benefits of RA to make an informed choice of anesthetic technique. Many studies that have investigated neurological complications after RA are dated, and do not reflect the(More)
BACKGROUND AND OBJECTIVES Popliteal sciatic nerve block (SNB) in combination with saphenous nerve block provides anesthesia and analgesia for foot and ankle surgeries. Landmark-based and image-guided techniques, to date, aim at blocking the sciatic nerve proximal to its bifurcation. Sciatic nerve block is usually associated with a long onset time (30-60(More)
BACKGROUND AND OBJECTIVES Patient-controlled analgesia (PCA) offers effective postoperative pain management. However, the evidence of economic benefits associated with its use is lacking. Although suggestive, the potential economic advantages of PCA in saving nursing time and shortening hospital stay need objective documentation. METHODS This study(More)
