  Sao Paulo Medical Journal - Contribution to the treatment of nausea and emesis induced by chemotherapy in children and ...
Emesis assessment was done on the basis of the following observations: anticipatory nausea and vomiting, nausea (presence or absence), dry heaving (number of episodes) and vomiting (frequency, duration and severity).
Emesis: The patients in the metoclopramide and granisetron groups presented with emesis in 33 (85%) and 13 (32.5%) chemotherapy treatments, or at rates of 2.175 and 0.500 episodes/treatment, respectively.
The mean number of emesis episodes in their chlorpromazine plus dexamethasone group was 3.5 times higher than the mean found in the metoclopramide plus dimenhydrinate group in our study, which also showed lower incidence of side effects.

Non—patient-related factors that influence a patient's susceptibility to emesis during treatment include the specific chemotherapy agent being used, dose (especially high doses), schedule, and route in which the suspected agent is given, as well as frequent-interval dosing and intravenous administration.
Acute Emesis (0 to 24 hours after chemotherapy): In terms of treating nausea and vomiting in patients who experience symptoms due to chemotherapy of high emetic risk (cisplatin and noncisplatin groups) within 24 hours after treatment, three agents are included in the 2006 guidelines.
For the prevention of anticipatory emesis, antiemetic treatment should be administered with initial chemotherapy and should be the most appropriate choice in terms of emetic risk for that particular chemotherapy agent.

Emesis was also investigated in fasting puppies using two barium sulfate 1 g gelatin capsules as a marker.

 CancerNetwork:
The third type of chemotherapy-related emesis is anticipatory emesis, which begins prior to the administration of chemotherapy, usually in patients whose emesis was poorly controlled during a previous chemotherapy cycle.
Since anticipatory emesis is believed to be a conditioned response that usually occurs in patients in whom emesis was poorly controlled during previous chemotherapy, good control of emesis during the first chemotherapy course remains the most effective means of prevention.
Be aware of the chemotherapy- and patient-related factors that influence the patterns and intensity of emesis, and choose the antiemetic regimen accordingly.
