Doctors from all over the world come to the United States to live better lives. But they often have to face issues during immigration. A recent clinical practice e-book, “How International Doctors Can Practice Medicine in United States Within 3 To 6 Months,” outlines all the issues foreign doctors face.

Drowning is a serious issue for pediatricians, and other medical professionals who treat children as the weather heats up and youngsters head to the pools. I'm aware that there can be some misunderstandings about certain drowning-related topics. Understanding the underlying pathophysiology of drownings is crucial in order to clarify some common misconceptions around this time of year. Dry drownings and secondary or delayed drownings are two concepts that are frequently misunderstood.

Oxygen Deprivation

When it comes to drownings, hypoxemia from water being aspirated into the lungs is the basis of the pathophysiology of drownings. It causes lung injury or the inability of oxygen to be transported from the alveoli to the blood. Because cells, tissues, and organs are oxygen-deprived and unable to function correctly, the end outcome is multisystem organ injury.

The most severe and obvious drowning problems are caused by the heart and brain. The myocardium ceases working without oxygen. As soon as the heart stops beating due to oxygen deprivation, other organs begin to suffer damage in a cascade fashion. Even if the remaining organs make it through the drowning and resume normal function, if the brain is deprived of oxygen, there can be serious damage that may not be reversible. The main objective of treatment and assistance is to quickly get oxygen back into the bloodstream to avoid severe harm to the heart and brain.

The Drowning Fears

In addition to the fear of drowning, there is also the fear of severe brain damage. Drowning-related death and disability are real concerns, and they regrettably occur frequently. With this in mind, misinformation concerning drownings can happen rather frequently, and families are particularly prone to be misled by what they learn from various informational sources and by incorrect interpretations of the pathophysiology of drownings. We frequently run into misconceptions about secondary or delayed drownings as well as dry drownings in the outpatient environment.

Drowning Misunderstandings

Really, there are only two appropriate classifications for drownings: deadly and nonfatal. Prior phrases such as delayed drownings, secondary drownings, delayed near-drownings, and dry drownings are incorrect. Either an adult or child escapes the drowning alive or dies trying. Nonfatal drowning refers to survival with or without permanent harm. A fatal drowning occurs to those who do not survive the drowning, either right away or some time afterward.

Dry drowning occurs when someone falls into the water without having any water in their lungs. People found dead in the sea without any fluid in their lungs gave rise to the idea. The basic theory of drowning is based on the idea that breathing in water causes lung dysfunction that prevents oxygen from reaching circulation. Therefore, the absence of fluid in the lungs usually indicates that the deceased was in the water at the time of their death and died of some other cause. There is the theory that when water tries to enter the airway, it causes the larynx to spasm shut. However, when there is a lack of oxygen, muscles often relax, and the larynx opens, eventually enabling water to enter the lungs.

After a drowning issue, the most frequent reason why we encounter kids in urgent care is probably a secondary or delayed drowning. The typical scenario is as follows:

A youngster briefly submerges in water, maybe aspirating fluid as demonstrated by subsequent coughing, but otherwise acting and breathing properly. Although there are no outward signs of harm following the incident, the parents are worried they might experience breathing issues and drowning symptoms in the hours, days, or weeks that follow.

Although some children may experience lung damage up to 8 hours after a significant aspiration, following drowning, they typically exhibit some symptoms, such as coughing, wheezing, difficulty breathing, lower oxygen levels than usual, or shortness of breath. After the drowning incident, a youngster without these signs is unlikely to experience lung damage hours later. Additionally, lung function will deteriorate hours rather than days or weeks following the damage. Therefore, the descriptions of secondary or delayed drownings—also referred to as "dry drowning" by parents—are inaccurate. It is referred to as a nonfatal drowning and not a delayed or secondary drowning If a kid experiences a serious bout of drowning, has progressive lung injury, does not require resuscitation, and is acting relatively normally after the drowning. The gradual lung injury has the same drowning mechanism, but the first symptoms are less severe since less water was sucked into the lungs. Minor drownings with developing symptoms typically have a very good prognosis. Children who require CPR after drowning or who exhibit evidence of brain impairment with a low level of consciousness right away are considered to have a bad prognosis for drowning.
