Intravenous insulin use: technical aspects and caveats

Area of Science:

• Endocrinology
• Pharmacology
• Critical Care Medicine

Background:

• Insulin has been used for nearly a century, with its clinical significance amplified in the last 15 years following studies on tight glycemic control.
• Intravenous (IV) insulin is a cornerstone in managing hyperglycemia in acute care and diabetic complications.
• However, IV insulin administration is prone to errors with potentially severe consequences.

Purpose of the Study:

• To highlight the critical importance of precise insulin injection techniques for effective hyperglycemia management.
• To emphasize the potential errors associated with IV insulin use and their clinical implications.
• To provide guidance on optimizing IV insulin administration in various clinical settings.

Main Methods:

• Review of current literature and clinical practices regarding IV insulin administration.
• Analysis of factors influencing IV insulin efficacy and safety, including preparation, dosage, and administration.
• Discussion of strategies to mitigate common errors and challenges in IV insulin therapy.
• Exploration of necessary improvisations for resource-limited settings.

Main Results:

• Effective hyperglycemia control relies heavily on meticulous attention to IV insulin preparation, dosage calculation, and administration protocols.
• Minimizing insulin adsorption to IV tubing and selecting appropriate devices are key to accurate dosing.
• Understanding potential interactions with IV fluids and implementing specific precautions are essential.
• Improvisation in injection techniques can significantly reduce morbidity and mortality in resource-constrained environments.

Conclusions:

• A comprehensive understanding of IV insulin injection techniques is vital for healthcare professionals to achieve optimal glycemic control and minimize adverse events.
• Standardizing and improving IV insulin administration practices can lead to better patient outcomes in acute care settings.
• Adapting techniques for resource-limited settings is crucial for equitable management of hyperglycemia and its complications.
