In order, the most common types of unintentional injuries are traffic accidents, falls, drowning, burns, and accidental poisoning.

[clarification needed][2] As of 2021, approximately 4.4 million people are killed due to injuries each year worldwide, constituting nearly 8% of all deaths.

[5] The United States Bureau of Labor Statistics developed the Occupational Injury and Illness Classification System (OIICS).

Traumatic injury is caused by an external object making forceful contact with the body, resulting in a wound.

Fourth-degree burns reach deep tissues such as muscles and bones, causing loss of the affected area.

Respiratory toxins can be released by structural fires, industrial accidents, domestic mishaps, or through chemical weapons.

The most severe injury associated with asphyxiation is cerebral hypoxia and ischemia, in which the brain receives insufficient oxygen or blood, resulting in neurological damage or death.

Specific injuries are associated with water inhalation, including alveolar collapse, atelectasis, intrapulmonary shunting, and ventilation perfusion mismatch.

This can be caused by azides, carbon monoxide, cyanide, smoke inhalation, hydrogen sulfide, methemoglobinemia-inducing substances, opioids, or other systemic asphyxiants.

[23] Injuries of overuse or overexertion can occur when the body is strained through use, affecting the bones, muscles, ligaments, or tendons.

[27] Abdominal trauma includes injuries to the stomach, intestines, liver, pancreas, kidneys, gallbladder, and spleen.

[33] The stomach is also well protected from injury due to its heavy layering, its extensive blood supply, and its position relative to the rib cage.

Injuries of the middle and internal ear may include a perforated eardrum or trauma caused by extreme pressure changes.

Exposure to corrosive chemicals can permanently damage the eyes, causing blindness if not sufficiently irrigated.

Ligament sprains and tendon strains are common injuries that do not require intervention, but the healing process is slow.

Stress fractures occur when the bone is overused or suffers under excessive or traumatic pressure, often during athletic activity.

Mild TBI, including concussion, often occurs during athletic activity, military service, or as a result of untreated epilepsy, and its effects are typically short-term.

This can be caused by stroke, a brain tumor, poison, infection, cerebral hypoxia, drug use, or the secondary effect of a TBI.

A catheter may be used to extract blood from the bladder in the case of hemorrhaging, though injuries that break the peritoneum typically require surgery.

They are rarely fatal, but they can produce a variety of complications, such as chronic discomfort, dyspareunia, infertility, or the formation of fistulas.

Age can greatly affect the nature of genital injuries in women due to changes in hormone composition.

Many cultures practice female genital mutilation, which is estimated to affect over 125 million women and girls worldwide as of 2018.

[56] The neck, including the pharynx and larynx, is highly vulnerable to injury due to its complex, compacted anatomy.

[59] Injuries to the diaphragm may present in many ways, including abnormal blood pressure, cardiac arrest, gastroinetestinal obstruction, and respiratory insufficiency.

Skin tears involve the removal of the epidermis or dermis through friction or shearing forces, often in vulnerable populations such as the elderly.

[citation needed] Emergency medicine during major trauma prioritizes the immediate consideration of life-threatening injuries that can be quickly addressed.

Opioid medications such as fentanyl, methadone, and morphine are used to treat severe pain in major trauma, but their use is limited due to associated long-term risks such as addiction.

[62] Complications may arise as a result of certain injuries, increasing the recovery time, further exasperating the symptoms, or potentially causing death.

[65] Excessive blood loss can cause hypovolemic shock in which cellular oxygenation can no longer take place.

Burn injuries in particular can cause dramatic changes in a person's appearance that may negatively affect body image.
