In this article the author intends to make a review of the most important indications and aims of mechanical ventilation, and the repercussion of artificial ventilation over the different systems of the body. The main kinds of ventilators used for the management of the critically ill patient, connected to a ventilator are reviewed.
Timely initiation of enteral feeding requires efficient placement of nasoenteric feeding tubes. It is generally agreed that postpyloric placement of feeding tubes reduces the risk of regurgitation and aspiration of feeding formulas. The authors describe a simple, economic method of achieving postpyloric placement of feeding tubes in most patients.
Nonoperative replacement of lost or occluded jejunal feeding catheters proved successful in 8 of 11 patients. This technique is recommended as a nonoperative means of replacing a needle catheter jejunostomy when it is accidentally lost or becomes occluded. Adherence to sterile technique and gentle advancement of the guide wire to avoid injury to the bowel are important. Since the technique depends on an established tract between the skin and the bowel, catheter replacement should not be attempted when the feeding catheter is lost or becomes occluded in the immediate postoperative period. In addition, confirmation of catheter patency and intraluminal position with sterile water-soluble contrast medium is critical to the safe use of this technique.

Upper gastrointestinal bleeding from isolated duodenal varices is a rare occurrence. We report the case of a patient with idiopathic duodenal varices in whom the diagnosis was established preoperatively by endoscopy. The patient did not have esophageal varices or portal hypertension, and he was treated by exicising the varix with a full thickness of duodenal wall. Bleeding has not recurred. Duodenal varices as well as duodenal ulcer and gastritis must be considered in evaluating a patient with cirrhosis and upper gastrointestinal bleeding.
