High pressure injection injuries: a serious occupational hazard

Area of Science:

• Occupational Safety and Health
• Trauma Surgery
• Toxicology

Background:

• High-pressure injection equipment (e.g., paint sprayers, grease guns) poses significant safety risks.
• These devices can inject contaminants like paint, solvents, and grease under extreme pressure (600-12,000 psi).
• Injection injuries can lead to widespread tissue damage, vascular compromise, systemic toxicity, and frequent amputations.

Purpose of the Study:

• To evaluate the characteristics and outcomes of high-pressure injection injuries.
• To highlight the severity and potential for amputation associated with these injuries.
• To emphasize the importance of timely medical and surgical management.

Main Methods:

• Retrospective review of 55 suspected high-pressure injection injury cases.
• Confirmation of 20 actual injection injuries based on equipment pressure (1,500-12,000 psi) and contaminant type.
• Analysis of injury patterns, treatment, and hospital admission duration.

Main Results:

• Twenty confirmed cases of high-pressure injection injuries were identified.
• Injected contaminants included latex paint, mineral spirits, and concrete sealer.
• Fourteen injuries affected digits, with three requiring digital amputation. Hospital stays averaged 6.5 days.

Conclusions:

• High-pressure injection injuries are a serious hazard requiring immediate medical attention.
• Early recognition and referral to specialized surgical care (orthopedic or plastic surgery) are critical.
• Effective management hinges on prompt diagnosis and appropriate surgical intervention to minimize morbidity and limb loss.
