The American Society of Anesthesiologists (ASA) Closed Claims database was started in 1985 to study anaesthesia injuries to improve patient safety, now containing 8954 claims with 5230 claims since 1990. Over the decades, claims for surgical anaesthesia decreased, while claims for acute and chronic pain management increased. In the 2000s, chronic pain management involved 18%, acute pain managem...

BACKGROUND Traumatic injury of the femur resulting in femoral fracture may result in significant postoperative pain. As with other causes of acute pain, regional anesthesia may offer a benefit over conventional therapy with intravenous opioids. This study prospectively assesses the effects of femoral nerve blockade with a lateral femoral cutaneous nerve block (FN-LFCN) on intraoperative anesthe...

aim and background:   intravenous regional anesthesia is easy to administer, reliable, and costeffective methods and materials:   in a randomized, double blinded, clinical trial thirty patients of 18 to 60 findings:   sensory block onset time, motor block onset time, tourniquet pain and analgesic conclusions:   addition of nitroglycerine to lidocaine to intravenous regional anesthesia can

objectives to compare an out-of-plane interscalene catheter technique to the in-plane technique in a randomized clinical trial. patients and methods eighty-four patients undergoing open shoulder surgery were randomized to either the in-plane or out-of-plane ultrasound-guided continuous interscalene technique. the primary outcome was vas pain rating at 24 hours. secondary outcomes included pain ...

Asthma is a variable disease with changes in symptoms and airway function over many time scales. Airway resistance (Raw) is variable and thought to reflect changes in airway smooth muscle activity, but just how variation throughout the airway tree and the influence of gas distribution abnormalities affect Raw is unclear. We used a multibranch airway lung model to evaluate variation in airway di...

BACKGROUND AND AIMS Ultrasonography has emerged as a novel, portable, non-invasive tool encouraging airway assessment and procedural interventions. This study assesses the feasibility of ultrasound for block of internal branch of superior laryngeal nerve (ibSLN) block during upper airway anaesthesia to aid awake fibre-optic intubation. METHODS Forty American Society of Anesthesiologists' phys...
