The valleculae can collect saliva to prevent initiation of the swallowing reflex. The vallecula is an important reference landmark used during intubation of the trachea. The procedure requires the blade-tip of a Macintosh-style laryngoscope to be placed as far as possible into the vallecula in order to facilitate directly visualizing the glottis .
One of the most common locations for a foreign body is the alimentary tract. It is possible for foreign bodies to enter the tract either from the mouth, [1] or from the rectum. [2] The objects most commonly swallowed by children are coins. [3] Meat impaction, resulting in esophageal food bolus obstruction is more common in adults. [4]
Medical plastics include a wide range of products from bags to pharmaceutical containers that leach and expose patients and healthcare workers to MNPs. [73] Further research is needed to assess toxicology and medical significance of MNPs from medical plastics. Microplastics per square meter in the EU sewage sludge (2015–2019) [74]
Scientists have studied the impact of plastic on the ecological environment for decades and have raised concerns about the health effects of some chemicals used in plastics.
Increased respiratory rate may be the only sign of foreign body aspiration in a child who cannot verbalize or report if they have swallowed a foreign body. [6] If the foreign body does not cause a large degree of obstruction, patients may present with chronic cough, asymmetrical breath sounds on exam, or recurrent pneumonia of a specific lung ...
The microplastics are such a concern because it is difficult to clean them up due to their size, so humans can try to avoid using these harmful plastics by purchasing products that use environmentally safe exfoliates. Because plastic is so widely used across the planet, microplastics have become widespread in the marine environment.
