Obstetrics and gynecology in the context of "Obstetrics"

Gestation is the period of development during the carrying of an embryo, and later fetus, inside viviparous animals (the embryo develops within the parent). It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time, for example in a multiple birth.

The time interval of a gestation is called the gestation period. In obstetrics, gestational age refers to the time since the onset of the last menses, which on average is fertilization age plus two weeks.

A surgical technologist (also called a surg tech, scrub, scrub tech, surgical technician, operating department practitioner or operating room technician) is an allied health professional working as a part of the team delivering surgical care. Surgical technologists are members of the surgical team, which include the surgeon, surgeon's assistant, scrub nurse, circulating nurse and anesthesia provider (anesthesiologist, anesthesiologist assistant or nurse anesthetist). They possess knowledge and skills in sterile and aseptic techniques. There are few mandatory professional requirements for surgical technologists, and the scope of practice varies widely across countries and jurisdictions. Surgical technologists attend junior colleges and technical schools, and many are trained in military schools. In the military they perform the duties of both the circulator and the scrub. The goal is for surgical technologists to be able to anticipate the next move the surgeon is going to make in order to make the procedure as smooth and efficient as possible.They do this by having knowledge of hundreds of surgical procedures and the steps the surgeon needs to take in order to complete the procedure, including the very wide range of surgical instruments they may need. Specialties can include, but are not limited to, the following: genitourinary, obstetrics and gynaecology, urology, ENT, plastics, general, orthopedics, neurology, and cardiovascular. They only work in surgical or perioperative areas and are highly specialized. Surgical technologist is the proper term for a two-year program which earns a degree in applied sciences. The profession is up and coming and highly in demand.

Obstetrics is the field of study concentrated on pregnancy, childbirth and the postpartum period. As a medical specialty, obstetrics is combined with gynecology under the discipline known as obstetrics and gynecology (OB/GYN), which is a surgical field.
