Which infusate do I need? Physiological basis of fluid therapy

Area of Science:

• Medical Science
• Physiology
• Pharmacology

Background:

• Intravenous fluid therapy utilizes various infusates to manage fluid balance and electrolyte levels.
• The selection of infusates is guided by specific physiological disturbances and therapeutic goals.

Purpose of the Study:

• To elucidate the rationale behind selecting different infusates for clinical use.
• To detail the physiological actions of commonly administered infusates.
• To describe the potential adverse consequences associated with infusate overadministration.

Main Methods:

• Literature review of physiological principles and pharmacological actions of infusates.
• Analysis of clinical guidelines and research on fluid therapy.
• Synthesis of information regarding infusate selection criteria and outcomes.

Main Results:

• Infusates serve to expand intravascular volume or modify body fluid solute composition.
• The choice of infusate is contingent upon the patient's specific physiological disturbances.
• Potential consequences of overinfusion, including fluid overload and electrolyte imbalances, are highlighted.

Conclusions:

• Appropriate infusate selection is critical for effective patient management.
• Understanding the actions and risks of infusates is essential for preventing adverse events.
• This review provides a foundation for informed decision-making in intravenous fluid therapy.
