What Researchers Did
Researchers conducted a retrospective study to assess the incidence, characteristics, and long-term residual symptoms of decompression illness (DCI) cases in Denmark between 1999 and 2013.
What They Found
They identified 205 DCI cases over the 15-year period, with an average of 14 cases annually and no significant trend. The most common symptoms were paraesthesia (50%), pain (42%), and vertigo (40%), and among a subgroup, 13 out of 30 divers had residual symptoms at discharge, with 6 out of 24 still experiencing symptoms at follow-up.
What This Means for Canadian Patients
Canadian divers should be aware of the persistent risk of decompression illness and its potential for long-term residual symptoms, even after treatment. This highlights the importance of safe diving practices and prompt medical attention for suspected DCI to minimize adverse outcomes.
Canadian Relevance
This study was conducted in Denmark and does not have a direct Canadian connection.
Study Limitations
The retrospective nature of the study and reliance on medical records and voluntary questionnaires may introduce limitations such as recall bias or incomplete data.
