As a result buy discount elimite 30gm line, lung scans are not used extensively to diagnose inhalation injury. TREATMENT Treatment of inhalation injury is largely supportive in nature. There are few specific treatments available, with the exception of identified systemic toxins such as CO or CN. Initially an advanced trauma life support (ATLS) survey and an airway, breathing, circulation (ABC) approach to resuscitation are indicated. Inhalation injury is usually encountered in combination with cutaneous burns. Inhalation injury increases the risk of acute respiratory distress syndrome (ARDS) and other pulmonary complications with severe cutaneous burns. Presence of inhalation injury also increases the volume of fluid required for resuscitation of the cutaneous burns. It is important to keep this in mind because underresuscitation will exacer- bate the effects of inhalation injury. All patients at risk for significant smoke exposure should have their carbo- xyhemoglobin level measured by co-oximetry. Standard therapy for CO toxicity has been 100% oxygen provided by tight-fitting mask or endotracheal tube. The half-life of carboxyhemoglobin is approximately 320 min for a person breathing room air and approximately 80 min when breathing 100% oxygen. Hyperbaric oxygen therapy further reduces the half-life and increases oxygen delivery by dissolved oxygen, but the relative risk–benefit relationships for this intervention are still controversial. When CN toxicity is suspected treatment is begun empirically based on a clinical diagnosis. Treatment includes administration of sodium thiosulfate (150 mg/kg over 15min) to convert cyanide to thiocyanate. In severe cases sodium nitrate (5mg/kg slowly intravenously) can be given to convert hemoglobin to methemoglobin, which will convert cyanide to cyanmethemoglobin [3a].
