Children can drown quickly and silently – it only takes 20 seconds and a few centimetres of water. One- and two-year-old children are particularly at risk. Near-drownings can have catastrophic consequences, and lead to permanent disabilities.
The events that result in drowning can be divided into the following sequence: (i) struggle to keep the airway clear of the water, (ii) initial submersion and breath-holding, (iii) aspiration of water, (iv) unconsciousness, (v) cardio-respiratory arrest and (vi) death – inability to revive.
The stages can take between 10 and 12 minutes before death occurs. If a child is drowning, it may happen much more quickly.
The amount of time children spend under the water while drowning usually determines their outcome. The lack of oxygen destroys brain cells and that causes damage to the brain, ranging from short term (forgetful, clumsy …) to severe (can't walk to vegetative).
“If your child inhales … water, watch them for 2 to 3 days to see if the child is having labored breathing, worsening cough, or fever. If that happens, make sure they are seen by a doctor because they could develop pneumonia if they [inhaled] some fluid into the lungs,” Shenoi says. General water safety is key, too.
Drowning adult:
Call 999. Perform chest compressions to the time of "Staying Alive". Do not give rescue breaths. Continue compressions until help arrives.
With so-called dry drowning, water never reaches the lungs. Instead, breathing in water causes your child's vocal cords to spasm and close up. That shuts off their airways, making it hard to breathe. You would start to notice those signs right away -- it wouldn't happen out of the blue days later.
New research shows that cold water drowning victims can be brought back to life as long as two hours after they drown if the right steps are taken. That means even if the heart has stopped beating and the victims' brains aren't getting the oxygen we all need to stay alive.
“If you can rescue a child before that and restore their breathing with CPR, and get their breathing back, usually the children will recover,” Dr. Goodman says. “After five minutes, there will be brain damage. It's just a matter of how severe.”
Results From 1993 to 2012, 160 children presented with cardiac arrest and hypothermia after drowning. In 98 (61%) of these children resuscitation was performed for more than 30 minutes (98/160, median duration 60 minutes), of whom 87 (89%) died (95% confidence interval 83% to 95%; 87/98).
Dry drowning and secondary drowning are both the result of injuries that happen underwater. Dry drowning sets in less than an hour after inhaling water. But secondary drowning, which is also rare, can happen up to 48 hours after a water accident. Secondary drowning is caused by water that accumulates in the lungs.
Secondary drowning is so rare that Dr. James Orlowski from Florida Hospital Tampa estimates that secondary or dry drowning account for no more than 1% to 2% of all drowning. The affected person will appear fine immediately after the incident, but over time the water in the lungs will cause swelling or edema.
The symptoms of dry drowning begin almost immediately after a drowning incident, while secondary drowning symptoms may start 1-24 hours after water enters the lungs. Symptoms may include coughing, vomiting, fever, diarrhea, difficulty breathing, chest pain, and lethargy.
Dr. Youngquist: Bring them up and lay them on a flat surface, hard surface and if they're not breathing on their own begin CPR and mouth-to-mouth resuscitation.
“Most drowning victims will have sustained cardiac arrest secondary to hypoxia. In these patients, compression-only CPR is likely to be ineffective and should be avoided. The first and most important treatment of the drowning victim is the immediate provision of ventilation.
This inhalation of water, also called aspiration, might be demonstrated in the moment it happens by just a small bout of coughing or gasping. That first coughing fit may end after a few moments. However, over the next several hours, the small amount of water that got into the lungs begins to wreak havoc.
Secondary drowning symptoms
Symptoms of secondary drowning may begin within four hours after being in the water. But they may not be apparent for 24 to 48 hours. According to the American College of Emergency Physicians, with secondary drowning in adults or children, you may notice: Difficulty breathing.
A person can drown in less than 60 seconds.
It has been reported that it only takes 20 seconds for a child to drown and roughly 40 seconds for an adult—and in some cases, it can take as little as a ½ cup of water to enter the lungs for the phenomenon to occur.
A drowning child usually can't call out. Instead of flailing her arms, she might use them to try to push up on the water's surface, which can look like normal playing. (Babies and younger toddlers might not move their arms much or at all.)
Drowning victims have recovered motor function as late as 48 h after resuscitation [127, 128]. CA data supports these findings [70, 71, 124, 129, 130].
Thousands of people survive drowning with no complications and sometimes they may have various degrees of brain damage from oxygen deprivation. That's why immediate rescue breaths are so vital prior to giving CPR to drowning patients.
This is a 91% survival rate. Conclusions: Bystander rescue and resuscitation play a critical role in the survival of drowning.
It's important to remember that it's possible to revive a person who has been underwater for a long time. The majority of near-drowning cases are attributed to accidents that occur near or in the water.
