Administer single-site 30-mL intramuscular injection?

Area of Science:

• Pharmacology
• Clinical Practice
• Drug Administration

Background:

• Intramuscular injections are a common route for drug administration.
• Traditional guidelines limit intramuscular injection volumes to 5 mL in adult patients to minimize discomfort and local tissue reactions.
• Fosphenytoin is an anticonvulsant medication often administered parenterally.

Purpose of the Study:

• To discuss the administration of a 30 mL intramuscular fosphenytoin dose.
• To evaluate the feasibility and safety of exceeding traditional intramuscular injection volume limits.
• To explore changes in clinical practice regarding intramuscular drug volumes.

Main Methods:

• A case report detailing the administration of 30 mL of fosphenytoin intramuscularly.
• Review of existing literature and guidelines on intramuscular injection volumes.
• Discussion of the clinical implications and potential benefits of larger volume injections.

Main Results:

• Successful administration of a 30 mL intramuscular fosphenytoin dose was achieved.
• The case suggests that larger intramuscular volumes may be feasible in certain clinical scenarios.
• No immediate adverse events related to injection volume were reported in this instance.

Conclusions:

• The traditional 5 mL limit for intramuscular injections in adults may be reconsidered for specific medications like fosphenytoin.
• Further research is warranted to establish safety and efficacy of larger intramuscular volumes.
• This case highlights a potential shift in drug administration practices for improved patient care.
