[Peripheral venous tolerance of hyperosmolar infusion solutions]

Area of Science:

• Clinical Nutrition
• Intravenous Therapy
• Patient Care

Background:

• Postoperative infusion therapy requires effective basic nutrition solutions.
• Peripheral venous tolerance is a key factor in selecting infusion therapies.
• High osmolarity solutions can pose risks to peripheral veins.

Purpose of the Study:

• To evaluate the peripheral venous tolerance of a novel amino acid and carbohydrate-based infusion solution.
• To compare this new solution's tolerance against commonly used hospital infusion fluids.
• To assess the safety of a high osmolarity nutrition solution in peripheral venous infusion.

Main Methods:

• A radiojodfibrinogen test was used to examine infusion thrombophlebitis.
• Thirty patients undergoing postoperative infusion therapy were included in the study.
• Peripheral venous tolerance was assessed after 48 hours of infusion.

Main Results:

• The novel nutrition solution has an osmolarity of 1100 mosm/l and energy content of 2400 kJ/l.
• Commonly used solutions included Ringer-solution (330 mosm/l), 5% glucose (280 mosm/l), and electrolyte glucose (407 mosm/l).
• Despite having three times higher osmolarity, the new solution showed no significant difference in peripheral venous tolerance compared to standard solutions after 48 hours.

Conclusions:

• The tested peripheral nutrition solution is well-tolerated in peripheral veins.
• High osmolarity does not necessarily equate to poor venous tolerance for this specific formulation.
• This finding supports the use of advanced nutrition solutions in postoperative infusion therapy.
