1/49. Symptomatic tracheal stenosis in burns.tracheal stenosis in burns is rare and usually results from prolonged intubation or tracheostomy. Inhalation injury itself has the potential risk of tracheal stenosis. We reviewed the records of 1878 burn patients during 1987 to 1995 and found seven with tracheal stenosis (0.37%) after an average of 4.4 years follow up. There were 4 males and 3 females with an average age of 27.3 years. The tracheal stenosis developed 1-22 months after burn (average 7 months). Five patients had their inhalation injury confirmed by bronchoscopic examination. The incidence of tracheal stenosis among inhalation injury patients was 5.49% (5/92). Six patients needed intubation in the initial stage either for respiratory distress or prophylaxis, with an average duration of 195.2 h. In addition to prolonged intubation, the presence of inhalation injury, repeated intubations and severe neck scar contractures are also contributors to tracheal stenosis in burns. We favor T-tube insertion as the first treatment choice; permanent tracheostomy was unsatisfactory in our study.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
2/49. Complete fusion of the vocal cords; an unusual case.A case is presented of a woman who sustained a 35% body surface area mixed depth cutaneous burn, together with a significant inhalational injury. The patient required emergency resuscitation with endotracheal intubation and subsequently tracheostomy. This resulted in an unfortunate complication of a total adhesion between the vocal cords which extended into the subglottic area, causing complete occlusion of the airway.- - - - - - - - - - ranking = 0.25keywords = injury (Clic here for more details about this article) |
3/49. Anhydrous ammonia burns case report and review of the literature.Chemical burns are associated with significant morbidity, especially anhydrous ammonia burns. Anhydrous ammonia is a colorless, pungent gas that is stored and transported under pressure in liquid form. A 28 year-old patient suffered 45% total body surface area of second and third degree burns as well as inhalational injury from an anhydrous ammonia explosion. Along with fluid resuscitation, the patient's body was scrubbed every 6 h with sterile water for the first 48 h to decrease the skin pH from 10 to 6-8. He subsequently underwent a total of seven wound debridements; initially with allograft and then autograft. On post burn day 45, he was discharged. The injuries associated with anhydrous ammonia burns are specific to the effects of ammonium hydroxide. Severity of symptoms and tissue damage produced is directly related to the concentration of hydroxyl ions. Liquefactive necrosis results in superficial to full-thickness tissue loss. The affinity of anhydrous ammonia and its byproducts for mucous membranes can result in hemoptysis, pharyngitis, pulmonary edema, and bronchiectasis. Ocular sequelae include iritis, glaucoma, cataracts, and retinal atrophy. The desirability of treating anhydrous ammonia burns immediately cannot be overemphasized. clothing must be removed quickly, and irrigation with water initiated at the scene and continued for the first 24 h. Resuscitative measures should be started as well as early debridement of nonviable skin. patients with significant facial or pharyngeal burns should be intubated, and the eyes irrigated until a conjunctivae sac pH below 8.5 is achieved. Although health care professionals need to be prepared to treat chemical burns, educating the public, especially those workers in the agricultural and industrial setting, should be the first line of prevention.- - - - - - - - - - ranking = 0.25keywords = injury (Clic here for more details about this article) |
4/49. hydrogen sulfide inhalation injury.hydrogen sulfide is a colorless, noxious gas with the distinctive smell of rotten eggs. This compound is a powerful reducing agent that is encountered in a number of industrial processes. When hydrogen sulfide is present, it exposes workers to the potentially lethal effects of the rapid hypoxemia that results from exposure to this agent. The "warning sign" is the characteristic smell of rotten eggs; this smell should alert anyone in the area that a potentially serious risk exists. The immediate removal of the victim and administration of high-flow oxygen is essential. Neurologic sequelae may require anticonvulsants and care must be exercised to observe for cardiac, hepatic, and renal insufficiency. Depending on the concentration, hydrogen sulfide can rapidly overcome a potential victim.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
5/49. Acute management of exposure to liquid ammonia.ammonia injury is an uncommon injury, but it is associated with high morbidity and mortality. This case report demonstrates the pathophysiology and treatment of both cutaneous burn wounds and inhalation injury caused by ammonia. Frequent bronchoscopy was used to attempt to avoid intubation and its associated morbidity. The patient remained extubated, but later he required skin grafts to close his wounds after healing of his pulmonary injury. A review of the management of inhalation injury is also discussed. ammonia injury can cause a severe inhalation injury. bronchoscopy can be a useful tool to avoid intubation.- - - - - - - - - - ranking = 1.75keywords = injury (Clic here for more details about this article) |
6/49. Successful reconstruction of extensive laryngotracheal strictures after inhalation burn injury: report of a case.We report a rare case of long segmental laryngotracheal stenosis following inhalation burn injury. The patient presented 2 months after his injury with progressive stridor and dyspnea necessitating tracheostomy. A computed tomographic scan of the neck revealed stenosis extending from the vocal cords to the top of the sternum. Repair was successfully carried out with multiple surgical procedures employing hinge-flap closure tented with autogenous tissue.- - - - - - - - - - ranking = 1.5keywords = injury (Clic here for more details about this article) |
7/49. Radionuclidic lung-imaging procedures in the assessment of injury due to ammonia inhalation.Clinical, physiologic, and bronchoscopic findings in a young man with acute injury of the respiratory tract due to inhalation of ammonia are described. Six months later, the patient's pulmonary function was reassessed by three radionuclidic lung-imaging procedures, which first revealed the sites and extent of the persisting obstructive disease processes. The diagnostic accuracy of the initial findings with radioactive xenon and aerosol were verified by the results of repeated bronchoscopic examination, bronchographic studies, standard pulmonary function tests, and lung-imaging procedures.- - - - - - - - - - ranking = 1.25keywords = injury (Clic here for more details about this article) |
8/49. survival of severe ARDS with five-organ system failure following burns and inhalation injury in a 15-year-old patient.OBJECTIVE: To show the effectiveness of an integrated therapeutical approach in a severe case of acute respiratory distress syndrome (ARDS) following burns, inhalation injury with therapy-refractory oxygenation under maximized ventilatory settings, and an overall complicated clinical course. PATIENT AND methods: Case report of a patient with severe inhalation injury and burns in an intensive care unit setting, undergoing cardiopulmonary resuscitation (CPR), nitric oxide (NO)-inhalation, surfactant-, kinetic-, and urodilatin-therapy. CASE REPORT: A 15-year-old male presented with deep dermal and full thickness thermal injuries involving 25% of his total body surface area. Shortly after presentation, the patient developed therapy-refractory respiratory failure, cardiac arrest, and subsequently suffered five-organ system failure (lung, heart, gastrointestinal, liver, kidney), in addition to burn injury, and ischemia related cerebral lesions. The patient was successfully treated with cardiac resuscitation, extra corporeal membrane oxygenation (ECMO), NO, kinetic therapy, surfactant, urodilatin, and other standard intensive care regimens. Three months post-trauma the patient was discharged home, nearly fully recovered. CONCLUSIONS: In a patient with severe ARDS, oxygenation failure under maximized ventilatory settings, and subsequent five-organ system failure, an integrated therapeutical approach comprising ECMO, NO, kinetic therapy, surfactant, and urodilatin did cross-bridge respiratory and vital functions, enabling overall survival.- - - - - - - - - - ranking = 1.75keywords = injury (Clic here for more details about this article) |
9/49. Long-term management of extensive tracheal stenosis due to formic acid chemical burn.We report on a 26-year-old woman who during early infancy (6 months) suffered from a chemical burn of the skin and upper airways due to spill of formic acid powder. Twenty years after the initial injury, she presented with dyspnea and stridor due to severe tracheal stenosis. Several interventional bronchoscopic manipulations were initiated: incision of the stenotic lesion with Nd:YAG laser and dilatation with a valvuloplasty balloon which enabled silicone stent placement which was subsequently kept in place for 3 years. Complications during the 4th year after stenting led to the successful replacement of this stent by two autoexpandable metallic stents covering the total length of the trachea from the subglottic area to the carina. In post-burn inhalation injuries, a complex inflammatory process may be active for many years after the initial insult. These injuries respond to prolonged tracheal stenting and a conservative approach is recommended.- - - - - - - - - - ranking = 0.25keywords = injury (Clic here for more details about this article) |
10/49. Case with bromine exposure leading to respiratory insufficiency.A 21-year-old male had a chemical burn on the right forearm when he inadvertently spilled bromine during an experiment. Since he inhaled vaporized bromine and had dyspnea and pharyngalgia, he arrived at our hospital in an ambulance as an emergency patient. On arrival, he kept a clear consciousness with a pulse rate of 98, body temperature of 36.8 degrees C, blood pressure of 132/80 mmHg, respiratory rate of 25, and oxygen saturation of 100%. (10 L/min of oxygen were administered.) He had marked dry coughs. His clothes had a foreign odor with mucosal irritation. Arterial blood gas analysis and blood biochemistry were normal. Based on these findings, he was diagnosed with chemical airway damage and bulbar conjunctiva from the exposure to bromine and a chemical burn on the right forearm. His respiratory condition became worse after admission, resulting in pulmonary edema. He was endotracheally intubated and controlled with an artificial ventilator on Day 3 after his injury. He was continuously treated with steroids and sivelestat sodium hydrate, which gradually improved his respiration. He was released from the artificial ventilator and extubated on Day 7. Although dyspnea associated with body movement and hoarseness persisted after extubation, the symptoms decreased and he was discharged on Day 41. This rare case is worth attention because serious respiratory insufficiency requiring artificial ventilation due to pulmonary edema from bromine exposure has not been reported in japan.- - - - - - - - - - ranking = 0.25keywords = injury (Clic here for more details about this article) |
