Tension pneumothorax as a complication of colonoscopy

The appearance of complications is not frequent following lower gastric endoscopy, and even less so in those which carry the risk of death. Within the low incidence, perforation is the second in frequency of appearance, following hemorrhage. Herein we present the case of a patient who developed acute respiratory failure on developing hypertensive pneumothorax secondary to colon perforation during therapeutic colonoscopy. The mechanism of production, the clinical manifestations and the treatment of this complication are reviewed.

Acute hepatic failure by phenytoin]

Two portable battery powered pulse oximeters were tested on Joint Services expeditions to the Sahara Desert and the Andes mountains. Their ability to measure changes in pulse, oxygen saturation of arterial haemoglobin (SaO2), their durability, ease of use, power systems and ancillary equipment were therefore evaluated in two extreme conditions. Although durable, easy to use and with good monitoring equipment, the batteries failed in extreme cold and the integral printer was too fragile for field use.
