Comparative Study Clinical TrialEndoscopic control of upper gastrointestinal hemorrhage with a bipolar coagulation device.
It has been difficult to determine the real efficacy of endoscopic treatment for upper gastrointestinal tract bleeding sites for several reasons. First, since 80 per cent of an unselected group are expected to stop bleeding spontaneously, it is important to focus upon those individuals who continue to bleed instead of a group in whom bleeding would have stopped spontaneously in the majority. Second, it is difficult, if not impossible, to have comparable groups of patients with similar lesions and similar rates of bleeding who can be randomized into different treatment groups. ⋯ This modality is relatively cheap compared with other devices, is theoretically less complicated and has minimal risk to the individual patient. Because of these considerations, it is a technique which deserves wider application and may become the endoscopic treatment of choice for control of upper gastrointestinal tract hemorrhage. Patients with endoscopic control of upper gastrointestinal tract bleeding avoid perioperative morbidity, have a lower transfusion requirement and may have a shorter hospital stay than comparable individuals who require operative control of bleeding sites.

The use of a Tiemann curved tip urethral catheter for repeated nasotracheal suction in 120 instances of postoperative pulmonary complications was proved to be more efficient than the use of a regular suction catheter. The curved tip is better adapted to the anatomy of the nasotracheobronchial tract and allows easy selective catheterization of the trachea and major bronchi.
