Comparative Study
The use of analgesics and sedatives in critically ill patients: physicians' orders versus medications administered.
To examine the difference between the prescribed and actually administered dose of analgesic and sedative drugs in critically ill patients. ⋯ Physicians tended to write fairly nonspecific orders that were used by the nursing staff as very broad guidelines. A need exists to educate physicians as to what patients actually receive for sedation and analgesia and at the same time improve the dialogue between nurses and physicians as to what patients actually require.

Multicenter Study
Risk factors for gastrointestinal bleeding in critically ill patients. Canadian Critical Care Trials Group.
The efficacy of prophylaxis against stress ulcers in preventing gastrointestinal bleeding in critically ill patients has led to its widespread use. The side effects and cost of prophylaxis, however, necessitate targeting preventive therapy to those patients most likely to benefit. ⋯ Few critically ill patients have clinically important gastrointestinal bleeding, and therefore prophylaxis against stress ulcers can be safely withheld from critically ill patients unless they have coagulopathy or require mechanical ventilation.

Review
Persistent paralysis in critically ill patients after the use of neuromuscular blocking agents.
Neuromuscular blocking agents (NMBAs), an important part of the pharmacologic armamentarium of the intensivist, have a long and admirable history of safety when used in the operating room for periods of time (almost always < 12 hrs). Since 1985, dozens of medical journals have reported a multitude of studies on persistent paralysis when these same agents are exported from the operating room to the ICU. Most of these reports are case presentations of patients who failed to move for days to weeks after discontinuation of NMBAs. ⋯ This article sorts through the issues surrounding persistent paralysis, and defines it as a short-term and a long-term problem. The short-term problem seems to have a pharmacologic explanation that is not difficult to correct. The long-term problem is much more complex and may have a toxic explanation that may also be more difficult to manage.

To describe the typical ranges for central venous oxygen saturation and PO2 in a group of critically ill neonates and the relationship of these measurements to measurements of arterial oxygenation and indicators of oxygen supply and demand. ⋯ We conclude that measurement of central venous oxygenation in ill neonates may reflect more accurately the oxygen supply and demand status of the neonate than measurement of arterial oxygenation alone.
