Abstract: Free air or gas in mediastinum is defined as pneumomediastinum. This is a rare condition which orginates from over distention of alveolus and alveolar rupture by barotrauma. A 6-year-old boy was admitted to our department with sudden onset, swelling of neck and face that developed during drinking water from tap by using his mouth. Physical examination revealed the presence of subcutaneous emphysema over the two side of the face that extended toward the neck bilaterally. The chest X-ray and CT of the thorax, when performed, revealed the diagnosis of pneumomediastinum and extrathoracic subcutaneous emphysema. Interestingly neither trachea-bronchial nor esophageal pathology was found by emergent rigid bronchoscopy and endoscopy for etiology of pneumomediastinum. Antibiotic treatment and oxygen therapy were given to the patient with chest pain and dyspnea. During the following days, the patient’s condition improved notably, with almost total resolution of the cervical emphysema and pneumomediastinum confirmed by daily chest X-ray and control thorax CT. He was discharged home after 6 days. The emphysema gradually resolved. Pneumomediastinum caused by barotrauma is a rare condition and only conservative treatment is required when the other causes are ruled out.

Abstract: barogenic rupture of the stomach is a rare complication following cardiopulmonary resuscitation, administration of nasal oxygen by catheter and diving accidents. we report a case of gastric barotrauma following oroesophageal intubation. in most cases, the tears occur along the lesser curvature, what have been already attributed to laplace's formula and, more recently, to morphological features of the stomach.

Revista Cubana de Medicina Militar , 2003,
Abstract: Se presenta el caso de un buzo que realizó una inmersión a 25 m de profundidad y al llegar a la superficie se le instaló un cuadro de cefalea occipital intensa con mareos y náuseas. Posteriormente presentó toma de la conciencia y focalización neurológica. En radiografía antero-posterior y lateral, tomografía computadorizada de cráneo, se observó un gran neumoencéfalo en hemisferio izquierdo y en osteoma en el seno frontal izquierdo. Se realizó una craneotomía frontotemporal izquierda con evacuación del neumoencéfalo. Posteriormente se observó mejoría neurológica y 48 h más tarde fallece por una infección respiratoria. El osteoma erosionó la pared posterior del seno frontal y subdural, lo que permitió la acumulación de aire subdural y no su salida por un mecanismo de válvula dural. The case of a diver that submerged at a depth of 25 meters and on arriving to the surface had occipital intense headache with dizziness and nausea was reported. Later, he presented taking of conciousness and neurological focalization. In antero-posterior and lateral radiographies and computerized tomography of the cranium it was observed a large pneumocephalus in the left hemisphere and an osteoma in the left frontal sinus. Left frontotemporal craniotomy with evacuation of the pneumocephalus was performed. Neurological improvement was observed and 48 hours later he died due to a respiratory infection. The osteoma eroded the posterior wall of the frontal and subdural sinus, which allowed the accumulation of subdural air and prevented its extraction by a mechanism of dural valve.

Abstract: ST-segment elevation, observed in the critically ill patients, almost always raises the suspicion of ischemic heart disease. However, nonischemic myocardial and non-myocardial problems in these patients may also lead to ST-segment elevation. Pneumothorax and pneumopericardium have been rarely reported as a cause of transient ST-segment elevation. The authors report the case of a patient admitted to the emergency care unit because of a respiratory failure requiring mechanical ventilatory support. As the patient showed signs of clinical deterioration, a pneumothorax was clinically diagnosed. Chest radiography after thorax drainage also disclosed a pneumopericardium. The 12-lead electrocardiogram recorded before the thoracic drainage revealed an ST-segment elevation, which normalized after the surgical procedure. Ischemic myocardial biomarkers were negative. The authors call attention to the right-sided pneumothorax associated with pneumopericardium as an unusual cause of ST-segment elevation.

Abstract: background and objectives: nowadays, severe anesthetic complications caused by the improper use of mechanical ventilators are rare. however, technical details even in recent models can be a trap for the anesthesiologist and threaten patient safety. the objective of this report was to demonstrate the importance of a careful analysis of the device to be used, as well as to detect and treat intraoperative tension pneumothorax. case report: a 16-year old female patient, physical status asa i, underwent corneal conjunctival covering under general anesthesia. anesthesia was maintained with isoflurane and controlled mechanical ventilation. no abnormalities were observed during anesthesia. at the final phase of the surgery, after mobilizing the anesthesia device to start the awakening process, the patient developed hypoxia, hypertension and ventilatory difficulties. after removal of the sterile drapes from the surgical field, subcutaneous emphysema was evident in the face, neck and upper limb. the tracheal cannula, which contained blood, was changed. a chest x-ray confirmed the diagnosis of pneumothorax that was immediately drained. inspection of the equipment revealed the presence of a kink in the tubing connecting the inferior portion of the canister to the equipment itself caused by mobilization of the articulated arm, blocking the normal flow of gases and leading to pulmonary barotrauma. conclusions: the development of tension pneumothorax during general anesthesia with positive pressure ventilation should always be considered. several factors can contribute to the development of this condition, which should be considered when they are present during surgeries. the anesthesia equipment should be examined carefully to detect potential causes of anesthetic complications.

Pakistan Journal of Biological Sciences , 2009,
Abstract: We present a rare case of facial paralysis that was unusual not only in its causation but also in its rapidity of onset and recovery. We describe a rare case history of this accruing in 35 years old women traveling at the high altitude mountain road referred to ENT clinic with sudden symptoms of middle ear effusion and facial nerve paralysis. Patient had undergone medical systemic steroid treatment and after 3-4 weeks she had a good recovery of facial palsy with a minimum remnant of sensory neural hearing loss. Facial nerve paralysis resulting from a barotrauma of the middle ear is suggested. The correct diagnosis of this condition is important and unnecessary treatment should be avoided.

Abstract: O barotrauma da orelha média ou barotite média (BM) é definido, segundo Armstrong & Hein, como uma inflama o traumática aguda ou cr nica causada por altera es da press o atmosférica. OBJETIVO: O objetivo deste estudo é analisar os aspectos clínicos relacionados ao barotrauma da orelha média em tripulantes da avia o civil. DESENHO DO ESTUDO: Clínico retrospectivo. MATERIAL E MéTODO: Foram avaliados 17 casos de BM no período de dezembro de 2002 a setembro de 2003, entre tripulantes atendidos no ambulatório de ORL do servi o médico da Funda o Ruben Berta/RJ (FRB/RJ). Em revis o dos prontuários foram colhidos e analisados dados relacionados ao sexo, idade, quadro clínico, evolu o e tratamento. RESULTADOS: No total dos casos, 11 eram homens e 6 mulheres; idade média de 37,3 anos. Todos apresentaram otalgia durante a descida do avi o. Catorze pacientes (82,4%) apresentavam queixa de plenitude aural. Zumbidos ocorreram em 2 pacientes. No momento do v o, onze pacientes (64,7%) apresentavam quadro sugestivo de infec o de vias aéreas superiores associada. O barotrauma foi de grau 1 de Teed em 17,6% dos casos, grau 2 em 58,8% dos casos e 23,6% grau 3. Nenhum paciente apresentou BM grau 4. O tratamento foi conservador em todos os casos, sendo preferida à utiliza o de antibióticos, corticosteróides e descongestionantes, por via oral. CONCLUS O: A BM é uma doen a peculiar à medicina aeroespacial e a otorrinolaringologia. A compreens o da fisiopatologia e mecanismos de preven o do barotrauma da orelha média é fundamental para manejo adequado destes pacientes.
