The effect of deep inspiration (DI) on airway responsiveness differs in asthmatic and normal human subjects. The mechanism for the effects of DI on airway responsiveness in vivo has not been identified. To elucidate potential mechanisms, we compared the effects of DI imposed before or during induced bronchoconstriction on the airway response to methacholine(More)
Active, nonanesthetized, tracheotomized rabbits were subjected to continuous positive airway pressure (CPAP) for 4 days to determine the effects of chronic mechanical strain on lung and airway function. Rabbits were maintained for 4 days at a CPAP of 6 cmH(2)O (high CPAP), at a CPAP of 0 cmH(2)O (low CPAP), or without tracheostomy (no CPAP). After treatment(More)
BACKGROUND Bedside ultrasound (BUS) can effectively identify fractures in the emergency department (ED). AIM To assess the diagnostic accuracy of BUS for fractures in pediatric trauma patients. SETTING AND DESIGN Prospective observational study conducted in the ED. MATERIAL AND METHODS Pediatric patients with upper and lower limb injuries requiring(More)
BACKGROUND Patients require procedural sedation and analgesia (PSA) for the treatment of acute traumatic injuries. PSA has complications. Ultrasound (US) guided peripheral nerve block is a safe alternative. AIM Ultrasound guided nerve blocks for management of traumatic limb emergencies in Emergency Department (ED). SETTING AND DESIGN Prospective(More)
Tracheobronchial foreign body aspiration (FBA) is a very common and lethal problem among children. It can easily be diagnosed with a typical history of choking crisis. Clinical examination and radiology play a secondary role in diagnosis. Acute choking episode may lead to death or else to serious sequels such as bronchiectasis, atelectasis, and recurrent(More)
