A case is presented of a 16-year-old girl with ectodermal dysplasia for whom dental surgery under general anaesthesia was planned. [ncbi.nlm.nih.gov]
[…] in the esophagus, the upper esophageal sphincter (UES) presents the next barrier to pulmonary aspiration. [mhmedical.com]
Entire Body System
- Hypoxemia
These findings usually included fever, tachypnea, diffuse rales, and serious hypoxemia. Cough, cyanosis, wheezing, and apnea were each seen in approximately one third of the cases. [ncbi.nlm.nih.gov]
Pulmonary aspiration can present symptoms of wheezing, coughing, dyspnea, cyanosis, pulmonary edema, hypotension, and hypoxemia, which may progress rapidly to severe acute respiratory distress syndrome (ARDS). [kjccm.org]
The CXR is mottled and the patient is prone to develop hypoxemia secondary to right to left intrapulmonary shunting. [quizlet.com]
[…] gastric tube (for example, a feeding tube ) may also increase the risk. [3] Consequences [ edit ] Particle-related [ edit ] Pulmonary aspiration of particulate matter may result in acute airway obstruction which may rapidly lead to death from arterial hypoxemia [en.wikipedia.org]
[…] difficulty, noisy breathing Chest pain Rapid heartbeat Low grade fever Weight loss Fatigue Blue coloring, especially lips and nail beds Blood-streaked mucus Increased mucus production Increased white blood cell production Tachypnea Tachycardia Transient hypoxemia [cme.ucsd.edu]
- Unconsciousness
ASPIRATION of gastric contents into the respiratory tract by the unconscious patient is a serious, and sometimes a fatal, hazard. [nejm.org]
Aspiration of stomach contents occurs during unconsciousness brought on by anesthesia, trauma, drug overdose or other circumstances. [buffalo.edu]
Unconscious people, babies and the very elderly also have poor cough reflexes, increasing their risk for aspiration. Aspiration leads to choking, asphyxiation and aspiration pneumonia. [news-medical.net]
Maternal pulmonary aspiration includes women with the following features: Women who have had an unprotected airway while unconscious, semi-conscious or paralysed AND A clinical history consistent with regurgitation of stomach contents and pulmonary aspiration [npeu.ox.ac.uk]
[…] trunk support Assure body, head and jaw alignment Use small-bore feeding tubes when possible Positioning Advise to change position every few hours Elevate head of bed 30-45 degrees Maintain internal and external alignment If patient must lie flat or is unconscious [cme.ucsd.edu]
Respiratoric
- Cough
Prevention Most people can prevent it by having a strong cough. Physiotherapy can help to develop and maintain the coughing muscles. [ada.com]
Symptoms of aspiration include: Coughing, choking, wheezing, rapid breathing and bad breath. [healthcentral.com]
Cough, cyanosis, wheezing, and apnea were each seen in approximately one third of the cases. Apena, shock, and early severe hypoxemia were particularly ominous events. [ncbi.nlm.nih.gov]
In that case, most of the time you’ll be able to prevent this by coughing. Those who have impaired coughing ability, however, may not be able to. [healthline.com]
In addition, any tiny amounts of inhaled fluid usually leads to a cough reflex which expels the fluid effectively without causing damage to the lungs. [news-medical.net]
- Respiratory Distress
Key Words: acute respiratory distress syndrome ; aspiration pneumonitis ; diffuse alveolar hemorrhage [kjccm.org]
Worsening of infiltrates after initial improvement was associated with the development of bacterial pneumonia, the adult respiratory distress syndrome, and pulmonary embolism. [ncbi.nlm.nih.gov]
Intubation is not required if there is no respiratory distress. [aast.org]
Differential diagnosis Other causes of respiratory distress, including: Other causes of pneumonia. Bronchiolitis. Croup. Epiglottitis. Foreign body in respiratory tract. Asthma. Cardiovascular disease. [patient.info]
- Hoarseness
Pulmonary symptoms range from a subtle cough, wheezing, or hoarseness to severe dyspnea or asphyxiation. We discuss the mechanism of pulmonary disease caused by aspiration as well as the appropriate treatment. [link.springer.com]
Symptoms of pediatric aspiration may include: Choking, coughing, or gagging while eating Weak sucking Fast or stopped breathing while feeding Hoarse voice or cry Noisy breathing or wheezing Slight fever after eating Chest discomfort or complaints of food [pedilung.com]
- Rales
These findings usually included fever, tachypnea, diffuse rales, and serious hypoxemia. Cough, cyanosis, wheezing, and apnea were each seen in approximately one third of the cases. [ncbi.nlm.nih.gov]
- Stridor
Bronchiectasis may follow. presentation of small particle partially obstructive aspiration is with dyspnoea, persistent coughing, wheeze, stridor and hypoxaemia non-obstructive particulate aspiration causes a clinical and radiological picture similar [aic.cuhk.edu.hk]
Gastrointestinal

This article presents two incidents involving diving-related vomiting with associated aspiration of gastric contents. [ncbi.nlm.nih.gov]
This manifests as reddish streaks of fresh blood in the vomit content. Further Reading What is Vomiting? Vomiting Mechanism Vomit Content Vomiting Causes Vomiting Social Implications [news-medical.net]
Cardiovascular
- Cyanosis
Cough, cyanosis, wheezing, and apnea were each seen in approximately one third of the cases. Apena, shock, and early severe hypoxemia were particularly ominous events. [ncbi.nlm.nih.gov]
Pulmonary aspiration can present symptoms of wheezing, coughing, dyspnea, cyanosis, pulmonary edema, hypotension, and hypoxemia, which may progress rapidly to severe acute respiratory distress syndrome (ARDS). [kjccm.org]
Clinically, this may be asymptomatic, or present as tachypnoea, bronchospasm, wheeze, cyanosis and respiratory insufficiency. [slideshare.net]

- Hypotension
Pulmonary aspiration can present symptoms of wheezing, coughing, dyspnea, cyanosis, pulmonary edema, hypotension, and hypoxemia, which may progress rapidly to severe acute respiratory distress syndrome (ARDS). [kjccm.org]
This fluid loss can result in relative hypovolemia and must be considered if hypotension develops. [quizlet.com]
Similarly, performing a rapid sequence induction (RSI) in a frail 80 year old could easily cause significant hypotension, which could affect spinal perfusion and subsequent neurologic recovery. [pocusjournal.com]
Psychiatrical
- Withdrawn
After planned endotracheal and nasogastric intubation for elective surgery, 20 participants had tracheal and gastric aspirates withdrawn. A blinded investigator tested samples for the presence of pepsin using the assay. [ncbi.nlm.nih.gov]
One must be concerned in the individual with risk for aspiration, that if an enteral feeding tube is eventually recommended, the sensory stimulation associated with eating would be withdrawn. [ct.gov]
Neurologic
- Seizure

- Agitation
CNS: Confusion, agitation, hallucinations, and seizures are known side-effects of cimetidine administration. [quizlet.com]
Treatment
Treatment Treatment depends on the severity of the aspiration. The aspirated objects or objects may need to removed by using a flexible camera to look at the windpipes. If pneumonia occurs, antibiotics might be given. [ada.com]
NM (nizatidine 150 + metoclopramide 10) Group C, F (famotidine 20 mg), and FM (famotidine 20 mg + metoclopramide 10) Group C,S (lafutidine 10), SD (lafutidine 10 + domperidone 10), and Group SM (lafutidine 10 + metoclopramide 10) Other Names: Drug treatment [clinicaltrials.gov]
Treatment from the outset by adrenocortical steroids or antimicrobial agents had no demonstrable effect on the outcome. [ncbi.nlm.nih.gov]
Treatment includes supplemental oxygen, steroids, or help from a breathing machine. Depending on the cause of chronic aspiration, you may require surgery. [healthline.com]

Prognosis
Patients with the most extensive radiographic abnormalities on initial studies tended to have the worst prognosis; however, mild early pulmonary infiltrates occasionally progressed to life-threatening abnormalities, and extensive initial involvement was [ncbi.nlm.nih.gov]
Treatment and prognosis differ by aspirated substance. Aspiration can cause lung inflammation (chemical pneumonitis), infection ( bacterial pneumonia or lung abscess ), or airway obstruction. [msdmanuals.com]
Prognosis This depends on the underlying cause, general well-being of the patient, presence of complications, speed of diagnosis and effective treatment. [patient.info]
Both community-acquired pneumonia (CAP) and hospital-acquired pneumonia have a worse prognosis if aspiration (defined by both clinical and radiologic features) is likely to be the inciting event ( 3 ). [unboundmedicine.com]
Etiology
Knight said these two etiologic agents have been shown to use different pathways in producing inflammatory lung injury. [buffalo.edu]
Etiology and Pathophysiology Aspiration pneumonia occurs when organisms dwelling in the oropharynx or stomach are introduced into the lungs in sufficient volume to cause clinical disease of infection. [unboundmedicine.com]
Epidemiology
Objectives To use the UK Obstetric Surveillance System (UKOSS) to describe the epidemiology, risk factors and outcomes of maternal pulmonary aspiration in pregnancy in the UK. [npeu.ox.ac.uk]
Epidemiology It is common. One study of elderly patients implicated aspiration pneumonia in 10% or cases of community-acquired pneumonia [ 1 ]. [patient.info]
Epidemiology Prevalence Prevalence data is difficult to assess given variations in the definition of aspiration pneumonia (radiographic, clinical, or bacteriologic classifications have all been used). [unboundmedicine.com]
Pathophysiology

PATHOPHYSIOLOGY OF ASPIRATION Natural barriers to aspiration include the lower esophageal sphincter, the upper esophageal sphincter, and the intrinsic protective airway reflexes. [mhmedical.com]
Ongoing basic science and clinical research are crucial for understanding the pathophysiology of aspiration-induced lung injury and developing novel therapeutic strategies. [aast.org]
Etiology and Pathophysiology Aspiration pneumonia occurs when organisms dwelling in the oropharynx or stomach are introduced into the lungs in sufficient volume to cause clinical disease of infection. [unboundmedicine.com]
Prevention
The maximum tilt used in this study was not adequate to prevent aspiration in the sniffing position. [ncbi.nlm.nih.gov]
Prevention Most people can prevent it by having a strong cough. Physiotherapy can help to develop and maintain the coughing muscles. [ada.com]
