What Researchers Did
This systematic review selected 17 studies to examine carbon monoxide (CO) poisoning in active or passive shisha tobacco smokers.
What They Found
Sixteen case reports, involving 39 patients (mean age: 22.3 years; males: 51.3%), described acute CO poisoning in active shisha smokers. The mean carboxy-haemoglobin (HbCO) blood level was 17.3%, and loss of consciousness occurred in 43.6% of patients.
What This Means for Canadian Patients
Canadian patients, particularly adolescents and young adults, should be aware that shisha smoking can lead to carbon monoxide poisoning. Healthcare providers should consider shisha use when diagnosing CO poisoning and offer appropriate cessation support.
Canadian Relevance
This study was conducted in France and does not have a direct Canadian connection.
Study Limitations
The findings are primarily based on case reports, which may limit the generalizability of the results.
