| assisted mechanical ventilation | <anaesthetics> The use of a mechanical device to fill the lungs with oxygenated air then allow time for passive exhalation. (27 Sep 1997) |
| assisted reproductive technology | Originally, a range of techniques for manipulating eggs and sperm in order to overcome infertility. Encompasses drug treatments to stimulate ovulation; surgical methods for removing eggs (e.g., laparoscopy and ultrasound-guided transvaginal aspiration) and for reimplanting embryos (e.g., zygot intrafallopian transfer (or ZIFT); in vitro and in vivo fertilization (e.g., artificial insemination and gamete intrafallopian transfer (or GIFT); ex utero and in utero foetal surgery; as well as laboratory regimes for freezing and screening sperm and embryos, and micromanipulating and cloning embryos. The field's first major success came in 1978 with the birth of "test-tube baby" Louise Brown, engineered by Steptoe, Edwards, et al., of England. As the technologies spread, they increasingly are being employed for purposes beyond infertility, i.e., to reduce the risk of, or avoid passing on, hereditary disease and to select for infant sex. Further uses that would aim at improving the "quality" of offspring have been widely discussed and raise profound legal and ethical questions. See: eugenics. (05 Mar 2000) |

| video-assisted thoracic surgery | A less morbid alternative to "open" thoracotomy that employs cameras, optic systems, percutaneous stapling devices, and assorted endoscopic graspers, retractors, and forceps. Also called video thoracoscopic surgery, it can be selectively applied to various pulmonary, pleural, and pericardial lesions. (05 Mar 2000) |
