Should parents worry about 'dry drowning'?

In the majority of cases, the risk of fatal drowning ends when a child leaves the water. But in rare instances, breathing problems can occur after a youngster has been submerged and rescued. We explore the signs parents need to watch out for.

Does dry or secondary drowning exist?

According to paediatrician and founder of Helper Bees, Dr Tamara Bugembe, 'dry' and 'secondary' drowning are terms that used to be used to describe breathing difficulties experienced after a range of water-related incidents.

However, Bugembe points out that, recently, there has been a move by medical professionals to stop using these terms because they can create ambiguity that may compromise the care a child receives. Indeed, following a WHO report, there is consensus that the terms 'wet', 'dry', 'active', 'passive', 'silent', and 'secondary' drowning should no longer be used. 

"Instead, the term 'drowning' is used to refer to all breathing difficulties that are related to water incidents, because the changes that are happening in the child's lungs are identical whether the exposure was to a large body of water or not," says Bugembe. 

So dry drowning - the idea that children can come to life-threatening harm after water exposure without any water getting into their lungs - is a myth. Unfortunately, drowning does happen, and children are at particular risk. 255 people died from accidental drowning in the UK in 2017, and drowning is the second or third most common cause of accidental death in children in the UK, Australia and the USA.

A life-threatening condition could potentially occur if someone has been partially submerged in water and rescued, but if at some point subsequent to that, a small amount of water will have entered their lungs. "This causes inflammation or swelling and makes it harder for the lungs to function," says Joe Mulligan, head of first aid education at the British Red Cross

They can also develop a condition called aspiration pneumonia as a consequence of germs in the water.

But it's a myth that drowning deaths can occur days or weeks after the incident with no preceeding symptoms, according to the American Red Cross:

"Brand new symptoms that develop days later are extremely unlikely to be related to the drowning episode. Importantly, the child should be evaluated for other conditions that might have caused the deterioration," says the charity. 

Symptoms to watch out for

Despite many scare stories in the media, there are no reported cases in medical literature of a child who suddenly experienced severe breathing problems days after being in the water, without experiencing prior symptoms. 

However, it's really important to be aware that signs can worsen in the hours after a drowning incident. Parents should look out for even seemingly mild symptoms. 

"The symptoms that your child may experience are linked to lung injury and reduced oxygen in the blood, including dizziness, tiredness, nausea, persistent coughing, difficulty breathing, chest pain and a change in behaviour," says Mike Dunn, deputy director of education and research of the Drowning Prevention Charity.

Bugembe adds: "Symptoms can range from spurts of coughing, wheezing, rapid breathing with nostrils flaring and an increased effort in breathing where your child has to really pull in at the base of their neck or under the ribcage to suck in sufficient air. Your child may also become irritable or lethargic and, in some cases, develop a fever.

"Pneumonia can sometimes develop after the initial event and this can take days to occur with similar symptoms as those I have already described," she says.

When should you seek help?

"If your child has fallen into the water, has nearly drowned or has inhaled a small amount of water, be aware of the risk and monitor them," says Dunn.

If they start to develop symptoms or feel ill, recognise that this could be linked to when they were swimming and seek medical attention straight away. Of course, it's important to mention to their doctor that they've also had a water-related incident. Bugembe says it's also helpful to know whether the water involved was salt water, chlorinated water or bubble bath water and the time it occurred.

"If your child already has any chest-related conditions such as asthma, please seek help sooner because their airways are more likely to react," she says.

She also recommends encouraging your child to cough and clear their airways as soon as the incident occurs.

"It's the most effective way to prevent the cascade of damage to the airways. Once the incident has occurred, observe your child closely. At bedtime, dress them in clothing that allows you to easily check on their effort of breathing," she says.

Prevention is key

Ultimately, the most effective drowning prevention is to ensure kids are not left unattended near water and are constantly supervised.

"Swim where there are lifeguards, particularly holiday resorts and beaches," says Dunn. Plus, teaching them to swim as early as possible can help prevent a drowning incident.

"Children can drown in as little as 5 centimetres of water," says GP Dr Sara Kayat. "So adult supervision is the order of the day and make sure you empty and tidy away any paddling pools after you've used them and put a net or a fence around garden water features."

For the past few days, I've been yawning a lot, much more than average (once every few minutes I feel the need). If I'm not yawning I'm breathing in as deep as I can to get similar "satisfaction"....
