Titanium tetrachloride (TiCl4) causes severe chemical burns by reacting with sweat. Prompt towel drying before irrigation is a unique, critical first-aid measure for these injuries.
Area of Science:
- Chemical Engineering
- Toxicology
- Dermatology
Background:
- Titanium tetrachloride (TiCl4) is a key intermediate in white pigment production.
- TiCl4 is known to cause severe chemical burns upon contact.
Observation:
- Two cases of severe full-thickness burns (18-20% total body surface area) caused by TiCl4 exposure are presented.
- The burns resulted from a combination of hydrochloric acid formation and heat generated by TiCl4 reacting with perspiration.
Findings:
- Immediate management involves towel drying before irrigation, a unique protocol for chemical burns.
- Wound healing was not significantly impaired by TiCl4, as indicated by biopsy immunostaining.
- Pulmonary and ophthalmologic involvement depend on exposure duration to TiCl4 vapor.
Implications:
- Clinical awareness of TiCl4's reactivity with water, including perspiration, is crucial for prompt and effective treatment.
- Early intervention can significantly limit the severity of TiCl4-induced chemical burns.
- Grafting is often necessary for these extensive full-thickness injuries.
