Iodine poisoning
Iodine is highly irritating and corrosive, causing significant damage to human skin and mucous membranes. Inhalation can injure the respiratory tract, leading to pneumonia and pulmonary edema. Oral ingestion can cause severe corrosive effects on the digestive tract, potentially burning the esophagus and gastric mucosa.
View detailsHypovolemic shock
Hypovolemic shock refers to a pathophysiological process caused by the loss of circulating volume due to various reasons, leading to a decrease in effective circulating blood volume and cardiac output, insufficient tissue perfusion (i.e., inadequate local or organ blood supply to tissues), cellular metabolic disorders, and functional impairment.
View detailsSnakebite poisoning
Snake envenomation refers to the local and systemic toxic reactions caused by the injection of venom into the body after a venomous snake bite, which can be life-threatening in severe cases. Farmers, fishermen, outdoor workers, and researchers involved in snake studies are susceptible to venomous snake bites.
View detailsAir embolism
The blood circulatory system is the pathway through which blood flows in the body, consisting of blood, blood vessels, and the heart. It is a closed transport system, powered by the continuous beating of the heart, which propels blood to circulate within this system, supplying blood and oxygen to various organs of the human body. Air embolism refers to the entry of air into blood vessels, which then travels through the bloodstream to obstruct the main pathway of the pulmonary artery, blocking blood supply to the lungs and heart, leading to severe ischemia and hypoxia in vital organs such as the lungs, heart, and brain. This condition is extremely rare, with a slightly higher incidence during or after childbirth (including miscarriage). Main symptoms include chest discomfort, dyspnea, cough, coma, and agitation. As the condition progresses, signs of shock such as decreased blood pressure, cyanosis of the limbs, and weak pulse may appear.
View detailsDrowning
Drowning is defined as the process of experiencing respiratory impairment from submersion or immersion in liquid. It leads to an inability to breathe, hypoxia, and asphyxial damage. It is more common in young and middle-aged adults. The main symptoms include choking, dyspnea, headache or visual disturbances, and chest pain.
View detailsHemorrhagic shock
Hemorrhagic shock is a type of hypovolemic shock, characterized by acute circulatory dysfunction caused by rapid and significant blood loss. Hemorrhagic shock is a common condition in emergency departments, often seen in cases of gastrointestinal ulcers with bleeding, or ruptured esophageal and gastric varices due to liver cirrhosis. Additionally, trauma and obstetric conditions can lead to severe hemorrhage and subsequent hemorrhagic shock.
View detailsTraumatic shock
Traumatic shock, also known as injury shock, refers to shock caused by severe trauma, especially when accompanied by a certain amount of bleeding. Shock can lead to multiple organ failure and even death. It is an acute critical illness that requires emergency treatment.
View detailsSedative-hypnotic drug poisoning
Sedative-hypnotic overdose is a condition caused by ingesting an excessive amount of sedative-hypnotic drugs, leading to symptoms such as drowsiness and coma. If left untreated, it can result in critical conditions like respiratory failure or circulatory collapse.
View detailsExcessive vitamin A intake
Excessive vitamin A intake is a condition caused by over-supplementation of vitamin A or consumption of too many vitamin A-rich foods, leading to a series of symptoms affecting the skin, bones, and central nervous system. Key manifestations include dry and rough skin and hair; generalized bone pain accompanied by edema; and central nervous system symptoms such as agitation, irritability, and somnolence.
