Headache may develop in flight passengers without underlying pathology even though this type of headache is not included in "The International Classification of Headache Disorders". We report on a case of headache which had developed during airplane landing. A rapid change in the ambient pressure may give rise to headache.

A self-inflating bag resuscitator is universally used to ventilate patients during cardiopulmonary resuscitation and transfer. This device can be reused after sterilization and reassembly, and the mis-assembly of a resuscitator can possibly happen. We report here on a case of mis-assembly of a resuscitator valve that resulted to barotrauma and instability of a patient.

Malfunction of the unidirectional valve in a breathing circuit system may cause hypercapnia from the rebreathing of expired gas, ventilation failure, and barotrauma. Capnography is a useful method for monitoring the integrity of the unidirectional valve. We experienced two cases of malfunction of a unidirectional valve which caused leakage and reverse flow, diagnosed early as a change of the capnographic waveform. One case was caused by expiratory unidirectional valve breakage. The other was caused by an incorrectly-assembled inspiratory unidirectional valve.

Pulmonary barotrauma during ascent is a common complication in SCUBA diving. One of the most severe forms of pulmonary barotrauma is a cerebral arterial gas embolism(CAGE). It is reported to account for about 30% of diving related deaths. The early recognition of CAGE is very important for the emergency physician because prompt hyperbaric recompression therapy can improve the clinical course. Thus, the emergency physician should know the clinical manifestation of CAGE to apply several treatment modalities early. We report a case of cerebral arterial gas embolism presented with hemiparesis and blurred vision immediately after SCUBA diving at 13 meters.

Colon barotrauma can be mostly caused by elevated intraluminal pressure. Air insufflation during colonoscopy procedure is the most common cause of iatrogenic colon barotrauma. Cat scratch colon can usually be seen in the mild type of colon barotrauma, and colon perforation can be seen in the severe type. We presently report a case of non-iatrogenic colon barotrauma caused by industrial compressed air. Multiple linear mucosal ulcers were noted in the recto-sigmoid colon, but the colon was not perforated. The patient was discharged without any further complications after conservative treatments.

High frequency jet ventilation (HFJV) has advantage for laryngomicrosurgery that the transit of a small airway tube through the surgical field causes much less interference with surgery. We experienced a case of tension pneumothorax during high frequency jet ventilation. The possible cause of barotrauma in this case was obstruction of gas escape. It is recommened that meticulous care is taken to ensure and adequate pathway for expiration when HFJV is used.

An air-compressor system takes atmospheric air, and filters, pressurises and dries it, before delivering it to the pipeline as a medical air. Because the air supplied by the air compressor may be used to wentilate patients or to drive surgical tools, its quality and purity must be carefully controlled. Atmospheric air contains a variable amount of water vapour but always more than is specified for medical air. Water vapour must be removed from medical air since it can damage surgical tools and some ventilators and can condense in low-lying parts of the pipeline system. Reeently we have had experience of pneumothorax by pulmonary barotrauma associated with obstruction of the ventilator exhalational valve. As a result of investigating the possible causes, we concluded the cause as high moisture content in the compressed air due to the malfunctioning air drier and filters. Therefore we submit this case report along with discussion and literature reviews.

Pharyngoesophageal perforation from an exploding bottle is an extremely rare injury. To date, twenty-four cases have been documented in English literature. In this study, we reported two additional cases of pharyngoesophageal perforation by a bottle exploding in the mouth. Explosion of the bottle occurred when the patients removed the cap of a home-made wine bottle with their teeth, which resulted in pharyngoesophageal perforation. The patients were managed by conservative treatment and operative repair, respectively. Both patients had an uneventful recovery. Possible mechanisms and preventive measures are discussed in this study, along with a review of the literature.

The endoscopic retrograde cholangiopancreatography (ERCP) has become a commonly performed endoscopic procedure in biliary pathology. ERCP is a relatively safe procedure. however, there are chance of potentially severe complications; pancreatitis, hemorrhage, infection, and perforation. Duodenal perforation, uncommon but severe complication of ERCP, occurred in less than 1% of most series. According to the related mechanism, anatomical location, and the severity of injury, three to four distinct types of perforations have been described. We experienced the barotrauma associated duodenal perforation during endoscopic hemostasis in patient with EST site bleeding. This duodenal perforation was related with excessive air inflation to maintain the patency of a lumen. Endoscopists performing ERCP should bear in mind that continued air inflation may lead to duodenal perforation.
