Nurses are forced to make decisions about feeding tube position at regular intervals during the delivery of tube feedings; failure to detect an improperly positioned feeding tube can have serious consequences. This study was designed to determine the extent to which specific indicators could singularly and collectively differentiate between gastric and small-bowel placement in patients with nasally or orally inserted small-bore feeding tubes. Indicators were the length of tubing extending from the tube's insertion site as well characteristics of aspirates withdrawn from the feeding tube (volume, appearance, and pH). ⋯ Univariate analysis showed that all four of the variables described above were able to differentiate between gastric and small bowel tube sites. A multivariate, forced entry, logistic regression model was able to correctly classify tube site in 81% of the predictions. A variety of easy-to-use bedside methods can be used with a moderate degree of confidence to distinguish between gastric and small-bowel tube placement during continuous feedings.

Case Reports
Value of triple H therapy in a patient with an ischemic penumbra following subarachnoid hemorrhage: a case study.
We report the case of a 43-year-old patient with delayed ischemic neurological deficit and an ischemic penumbra, reversed with triple H therapy (hypertension, hypervolemia, and hemodilution). The patient presented with subarachnoid hemorrhage caused by an aneurysm of the anterior communicating artery. ⋯ Permanent damage to the area of ischemic brain was prevented by institution of the triple H therapy. He recovered and was discharged with no subsequent neurological deficits.
