What Researchers Did
Researchers reviewed the medical records of 200 recreational divers treated for decompression illness (DCI) to understand the types and timing of their neurological symptoms.
What They Found
This study found that 88.5% of 200 recreational divers treated for DCI experienced at least one neurological symptom, with symptoms typically appearing within 60 minutes of surfacing. Common symptoms included tingling, numbness, poor coordination, muscle weakness, and dizziness. Younger and less experienced divers were more likely to report tingling sensations, while female divers more often experienced painful skin symptoms.
What This Means for Canadian Patients
Canadian divers experiencing neurological symptoms after a dive, such as tingling, dizziness, or weakness, should seek immediate medical attention for potential decompression illness (DCI). Recognizing that symptoms can appear within an hour and are common, especially in younger or less experienced divers, can help in early diagnosis and treatment. Hyperbaric oxygen therapy is a recognized treatment for DCI in Canada.
Canadian Relevance
This study covers decompression sickness, which is a Health Canada-recognized indication for hyperbaric oxygen therapy.
Study Limitations
As a retrospective review of existing medical charts, this study's findings are based on past data and may not capture all factors influencing DCI outcomes.
