Two divers in Quang Tri Province surfaced abruptly from a depth of 15-20 metres, causing decompression sickness that left one dead and the other in critical condition.
On September 22, the Vietnam-Cuba Friendship Hospital in Dong Hoi received the two divers from Nam Trach Commune. One man, aged 45, died despite intensive care, while the other, aged 54, was stabilised and transferred to the Vietnam Maritime Medicine Institute in Haiphong for hyperbaric oxygen treatment.
According to family members, the pair were forced to surface suddenly about two hours after starting their dive due to technical problems. Both showed signs of exhaustion, shortness of breath and cyanosis before being rushed to hospital.
Doctors said the 45-year-old was conscious but had severe cyanosis, respiratory distress, wet rales in the lungs and acute abdominal pain. Despite intubation, mechanical ventilation and resuscitation efforts, he suffered cardiac arrest and could not be revived.
The 54-year-old was admitted conscious but with oxygen saturation at only 80 per cent, rapid heartbeat and mild pulmonary rales. After respiratory support, intravenous fluids and medication, his condition stabilised before transfer.
Dr Nguyen Dai Viet Duc, head of the intensive care and anti-poison department, confirmed both cases were caused by decompression sickness. When divers ascend too quickly, nitrogen dissolved in blood and tissues forms bubbles that obstruct circulation, damage cells and trigger inflammatory responses.
The condition can cause brain, spinal cord, lung and heart damage, leading to paralysis, respiratory failure and circulatory shock if not treated promptly.
