The Parkland Formula is used to determine the volume of fluid required for resuscitation of burn patients . It is 4 mL x body weight in kg x % total body surface area of the burn. Half of this fluid is given within the first 8 hours and then other half over the next 16 hours . Pneumoconiosis is a restrictive lung disease that can be caused by inhalation of dust , often in mines . It presents with bilateral ground glass opacities on Chest X-ray. The Median Nerve Compression Test is the most sensitive test for confirming carpal tunnel syndrome . It consists of direct pressure application to the median nerve at the carpal tunnel. Hypotension and hypoxia have both been shown to have a devastating effect on the outcome of patients with traumatic brain injury . That wraps up RoshCast Episode 48!
