Seven misconceptions regarding volume therapy strategies—and their correction
| The first 150 words of the full text of this article appear below. |
An appropriate intravascular volume replacement is a fundamental component of managing the critically ill surgical or intensive care unit (ICU) patient because the failure to treat hypovolaemia may progress to organ dysfunction or even death.1 Although the importance of adequate volume replacement is widely accepted, there are still no unique accepted recommendations. Aside from different crystalloid solutions, the natural colloid human albumin (HA) and different non-protein (synthetic) colloids have been promoted to treat volume deficits. Over the recent years, some misconceptions or myths of volume replacement concepts have been established that need to be reconsidered and to be corrected when necessary.
First misconception: saline is a physiological solution
Saline solution is an isotonic crystalloid that is still the dominating crystalloid worldwide. It has been termed physiological or normal saline, but when it is compared with the composition of plasma, one must wonder why it has ever been termed as physiological. With its high sodium (154 mmol litre–1
Second misconception: albumin is superior to other plasma substitutes
Third misconception: all colloids are the same
Fourth misconception: crystalloids are as effective as colloids
Fifth misconception: use of pressure-related monitoring variables to guide volume therapy
Sixth misconception: mortality is the only variable that counts for assessing the quality of volume replacement strategies
Seventh misconception: the myth of meta-analyses
