How safe are intramuscular injections?

Area of Science:

• Pharmacology and Therapeutics
• Clinical Medicine
• Patient Safety

Background:

• Intramuscular injections are a common drug administration route.
• Potential adverse effects and contributing factors require thorough understanding.
• Existing guidelines may not adequately address risks in critical care.

Purpose of the Study:

• To provide an overview of adverse effects linked to intramuscular injections.
• To identify factors that contribute to these adverse events.
• To propose updated guidelines for drug administration via intramuscular route for general and critical care patients.

Main Methods:

• Comprehensive review of existing research literature.
• Analysis of case history data.
• Evaluation of current drug administration guidelines.

Main Results:

• Detailed overview of various adverse effects associated with intramuscular injections.
• Identification of key factors influencing the occurrence and severity of adverse effects.
• Evidence supporting the need for re-evaluation of the intramuscular route in critical care.

Conclusions:

• The intramuscular route may pose significant risks for critical care patients.
• Recommendations are made to reconsider the appropriateness of this route for drug administration in critical care settings.
• Avoidance of intramuscular injections for most critically ill patients is advised.
