ABCs
The first three aspects of a patient to check in an emergency--Airway (taking care with the spine), Breathing, and Circulation (with attention to bleeding).

abortifacient
A substance or device that causes abortion.

abortion

The spontaneous or induced termination of pregnancy before fetal viability. Complete--all products of conception are expelled. Incomplete--some products of conception remain in the uterus. Elective--voluntary termination of pregnancy. Inevitable--cannot be stopped. Missed—the embryo dies, and products of conception are retained. Septic--pregnancy loss complicated by infection of the products of conception. Spontaneous--expulsion of products of conception before 20th week of gestation. Therapeutic--medically sanctioned pregnancy termination performed when pregnancy endangers the mother’s health or when the fetus has a known life-limiting or fatal condition. Threatened--bleeding from uterus or cramping that may or may not result in loss of the pregnancy.

abrasion
Scraping away of tissue, often skin or mucous membrane, usually superficial.

ACLS
Advanced Cardiac Life Support.

​active labor
First-stage labor, between about 6 and 10 cm dilation. The rate of cervical cervical change increases and contractions usually grow longer, stronger, closer, and more regular.

adhesion
Union of normally separate parts, as during healing of a wound or infection. Surgery, inflammation, or trauma may create adhesions—scar tissue that binds tissues together abnormally, causing pain and organ dysfunction.

acute respiratory distress syndrome (ARDS)
Severe, acute lung dysfunction that occurs as a result of illness or injury involving an accumulation of fluid in the alveoli (air sacs) in the lungs. It becomes difficult for oxygen to move into the circulating blood and the person may develop inadequate levels of oxygen in bloodstream (hypoxemia). ARDS may develop if the body is compromised by widespread infection (sepsis) or as a result of pneumonia, trauma, shock, severe burns, toxic inhalations, aspiration of food or chemicals into the lung, multiple blood transfusions, or in response to other conditions. 

afterpains
Cramps caused by the contractions of uterine involution during the first few days after childbirth.

ALS
Advanced Life Support

amenorrhea
Absence or cessation of menstruation. Primary—Primary amenorrhea is the absence of menses at age 15 years of age in the presence of normal growth and secondary sexual characteristics. Secondary--Secondary amenorrhea is the cessation of regular menses for three months or the cessation of irregular menses for six months.

amniocentesis
