| monitoring, intraoperative | The constant checking on the state or condition of a patient during the course of a surgical operation (e.g., checking of vital signs). (12 Dec 1998) |
|---|---|
| intraoperative care | Patient care procedures performed during the operation that are ancillary to the actual surgery. It includes monitoring, fluid therapy, medication, transfusion, anaesthesia, radiography, and laboratory tests. (12 Dec 1998) |
| intraoperative complications | Disorders affecting patients during surgery. They may or may not be related to the disease for which the surgery is done. They may or may not be direct results of the surgery. (12 Dec 1998) |
| intraoperative period | The period during a surgical operation. (12 Dec 1998) |
| intraoperative radiation therapy | Treating a tumour site withradiation immediately following surgery to destroy the tumour. (09 Oct 1997) |
| real-time ultrasonography | Rapid serial ultrasound images produced using a phased array or scanning transducer; produces a video display of organ motion, such as heart valve or foetal motion. (05 Mar 2000) |
| gray-scale ultrasonography | The display of the ultrasound echo amplitude or signal intensity as different shades of gray, improving image quality compared to the obsolete black and white presentation. (05 Mar 2000) |
| Doppler ultrasonography | Application of the Doppler effect in ultrasound to detect movement of scatterers (usually red blood cells) by the analysis of the change in frequency of the returning echoes.In many instances, ultrasound has supplanted x-radiography as the imaging method of choice, because it poses no risk to patients, is noninvasive, and of moderate cost. Doppler-corrected ultrasound enables real-time viewing of tissues, blood flow, and organs that cannot be obtained by any other method. It has proved a boon to cardiology, greatly aiding evaluations of cardiovascular patients, and to obstetrics, where it is used for foetal monitoring. (05 Mar 2000) |
| duplex ultrasonography | The combination of real-time and Doppler ultrasonography. (05 Mar 2000) |
| endovaginal ultrasonography | Pelvic ultrasonography using a probe inserted into the vagina. (05 Mar 2000) |
| ultrasonography | <investigation, procedure> A technique in which high-frequency sound waves are bounced off internal organs and the echo pattern is converted into a 2 dimensional picture of the structures beneath the transducer. (12 May 1997) |
| ultrasonography, doppler | Ultrasonography applying the doppler effect, with frequency-shifted ultrasound reflections produced by moving targets (usually red blood cells) in the bloodstream along the ultrasound axis in direct proportion to the velocity of movement of the targets, to determine both direction and velocity of blood flow. (12 Dec 1998) |
| ultrasonography, doppler, colour | Ultrasonography applying the doppler effect, with the superposition of flow information as colours on a gray scale in a real-time image. This type of ultrasonography is well-suited to identifying the location of high-velocity flow (such as in a stenosis) or of mapping the extent of flow in a certain region. (12 Dec 1998) |
| ultrasonography, doppler, duplex | Ultrasonography applying the doppler effect combined with real-time imaging. The real-time image is created by rapid movement of the ultrasound beam. A powerful advantage of this technique is the ability to estimate the velocity of flow from the doppler shift frequency. (12 Dec 1998) |
| ultrasonography, doppler, pulsed | Ultrasonography applying the doppler effect, with velocity detection combined with range discrimination. Short bursts of ultrasound are transmitted at regular intervals and the echoes are demodulated as they return. (12 Dec 1998) |
