There remains considerable controversy over the mechanism of radiation-induced emesis. It is well known that the abdomen is the most sensitive site; therefore it is unlikely that emesis results from a direct action on any central neural : David O Carpenter.

Mechanism of radiation-induced emesis by David O. Carpenter. Published by Defense Nuclear Agency in Washington, DC. Written in English. Nausea and vomiting following radiation exposure are factors which may seriously limit the ability of humans to perform in military situations and are side effects of such significance in radiation therapy that they may limit the patient's acceptance of treatment regimes (1).

At doses of Gy approximately 50% of humans experience nausea and vomiting, while at Gy the figure approaches %.Author: David O Carpenter.

Scientific investigation has defined the basic physiology of radiation-induced emesis, but the underlying mechanisms and the definition of an effective anti-emetic regimen remain unresolved. Within that context, this paper will review the radiobiology of emesis and the implications of the current research (see Fig.

The intensity and severity of emesis will vary according to the site treated, the daily and total dose delivered, prior cytotoxic therapy, and the psychological and metabolic state of the by:   [3,12] These studies have reported the abdomen or pelvic region to be the most critical organs responsible for radiation-induced emesis.

Similarly, Enblom et al [ 3 ] study reported that nausea was more frequent in those receiving RT to the lower abdomen or pelvis compared to the head and neck area radiated by: 3. At or near the top of their concerns is the common adverse effect (AE) of chemotherapy-induced nausea and vomiting (CINV).

When CINV goes untreated, it affects upwards of 60% to 80% of. A similar mechanism has been proposed to explain the beneficial effects of nonsteroidal anti-inflammatory drugs in nausea and vomiting induced by systemic irradiation.

The introduction of new antiemetics has resulted in renewed interest in the etiology and control of radiation-induced emesis. Studies both with fractionated treatment and with high-dose single exposures have clearly demonstrated the value of the 5-HT 3 receptor antagonist antiemetics.

This paper reviews the selection of optimal by: The mechanism of radiation-induced emesis remains unclear, but release of serotonin from the gastrointestinal enterochromaffin cells and subsequent involvement of the gastrointestinal 5-HT 3 receptors and vagal afferent fibers is most likely.

Reviewer: Description: Nausea and vomiting are high on the list of distressing symptoms of cancer and its treatment. This first edition book is a comprehensive and authoritative resource regarding recent developments on the mechanisms underlying treatment-induced nausea and vomiting, pharmacologic management, and methods for evaluating antiemetic Price: $ Background Radiation-induced nausea and vomiting (RINV) is common occurrence in cancer patients treated with radiotherapy.

When radiation is prescribed to certain sites, it can lead to retching. Vomiting is a forceful expulsion of the contents of the stomach and sometimes the gut. The whole mechanism is guided and controlled by the brain and its vomiting centre.

Vomiting is the forceful expulsion of contents of the stomach and often, the proximal small intestine. It is a manifestation of a large number of conditions, many of which are not primary disorders of the gastrointestinal tract.

Regardless of cause, vomiting can have serious consequences, including acid-base derangments, volume and electrolyte.

Nausea or vomiting is caused by a variety of medications or other noxious agents. The overall goal of treatment should be to prevent or eliminate nausea and vomiting regardless of etiology. Treatment options for nausea and vomiting include drug and nondrug modalities such as relaxation, biofeedback, and self-hypnosis.

The mechanisms underlying radiation-induced emesis are poorly understood. For example, in dog (11) it has been reported that integrity of area postrema is critical but that vagal integrity is not. In the cat it is reported that the vagus is the primary path-way for radiation-induced emesis (12).
