Dive Injury and Jellyfish Sting Case Study

Area of Science:

• Marine biology
• Diving medicine
• Toxicology

Background:

• Divers face risks from hazardous marine wildlife encounters, potentially leading to panic and uncontrolled ascents.
• Such incidents can increase the risk of decompression illness (DCI), particularly pulmonary overinflation syndrome (POIS).
• Medical assessment can be compromised if focused solely on wildlife injuries, potentially overlooking critical conditions like DCI.

Purpose of the Study:

• To highlight the potential for marine wildlife encounters to complicate dive safety and medical evaluations.
• To emphasize the importance of a comprehensive medical assessment in divers following hazardous encounters.
• To present a case illustrating the differential diagnosis between marine envenomation and diving-related injuries.

Main Methods:

• Case report analysis of a SCUBA diver experiencing chest pain post-dive.
• Review of immediate medical interventions for suspected Portuguese man-of-war envenomation.
• Differential diagnosis considering both marine envenomation and diving-related pathologies.

Main Results:

• A diver with suspected marine envenomation and chest pain was treated and recovered fully.
• Initial assessments ruled out acute diving-related injuries like DCI.
• The diver was cleared for return to diving after a one-month follow-up with no residual symptoms.

Conclusions:

• Marine wildlife encounters pose significant risks to divers, including potential for DCI.
• Comprehensive medical evaluation is crucial to differentiate between envenomation symptoms and diving-specific injuries.
• Vigilance against diagnostic overshadowing is essential for optimal diver care and safety.
