Antiemetics: Drugs used to prevent NAUSEA or VOMITING.Vomiting: The forcible expulsion of the contents of the STOMACH through the MOUTH.Ondansetron: A competitive serotonin type 3 receptor antagonist. It is effective in the treatment of nausea and vomiting caused by cytotoxic chemotherapy drugs, including cisplatin, and has reported anxiolytic and neuroleptic properties.Nausea: An unpleasant sensation in the stomach usually accompanied by the urge to vomit. Common causes are early pregnancy, sea and motion sickness, emotional stress, intense pain, food poisoning, and various enteroviruses.Postoperative Nausea and Vomiting: Emesis and queasiness occurring after anesthesia.Prochlorperazine: A phenothiazine antipsychotic used principally in the treatment of NAUSEA; VOMITING; and VERTIGO. It is more likely than CHLORPROMAZINE to cause EXTRAPYRAMIDAL DISORDERS. (From Martindale, The Extra Pharmacopoeia, 30th ed, p612)Metoclopramide: A dopamine D2 antagonist that is used as an antiemetic.Droperidol: A butyrophenone with general properties similar to those of HALOPERIDOL. It is used in conjunction with an opioid analgesic such as FENTANYL to maintain the patient in a calm state of neuroleptanalgesia with indifference to surroundings but still able to cooperate with the surgeon. It is also used as a premedicant, as an antiemetic, and for the control of agitation in acute psychoses. (From Martindale, The Extra Pharmacopoeia, 29th ed, p593)Granisetron: A serotonin receptor (5HT-3 selective) antagonist that has been used as an antiemetic for cancer chemotherapy patients.Phenothiazines: Compounds containing dibenzo-1,4-thiazine. Some of them are neuroactive.Vomiting, Anticipatory: Vomiting caused by expectation of discomfort or unpleasantness.Acupressure: A type of massage in which finger pressure on specific body sites is used to promote healing, relieve fatigue, etc. Although the anatomical locations are the same as the ACUPUNCTURE POINTS used in ACUPUNCTURE THERAPY (hence acu-), no needle or other acupuncture technique is employed in acupressure. (From Random House Unabridged Dictionary, 2d ed). Shiatsu is a modern outgrowth that focuses more on prevention than healing.Serotonin 5-HT3 Receptor Antagonists: Drugs that bind to but do not activate SEROTONIN 5-HT3 RECEPTORS, thereby blocking the actions of SEROTONIN or SEROTONIN 5-HT3 RECEPTOR AGONISTS.Serotonin Antagonists: Drugs that bind to but do not activate serotonin receptors, thereby blocking the actions of serotonin or SEROTONIN RECEPTOR AGONISTS.Neurokinin-1 Receptor Antagonists: Compounds that inhibit or block the activity of NEUROKININ-1 RECEPTORS.Acupuncture Points: Designated locations along nerves or organ meridians for inserting acupuncture needles.Dexamethasone: An anti-inflammatory 9-fluoro-glucocorticoid.Antineoplastic Agents: Substances that inhibit or prevent the proliferation of NEOPLASMS.Double-Blind Method: A method of studying a drug or procedure in which both the subjects and investigators are kept unaware of who is actually getting which specific treatment.Neoplasms: New abnormal growth of tissue. Malignant neoplasms show a greater degree of anaplasia and have the properties of invasion and metastasis, compared to benign neoplasms.Pain, Postoperative: Pain during the period after surgery.Cisplatin: An inorganic and water-soluble platinum complex. After undergoing hydrolysis, it reacts with DNA to produce both intra and interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity of cisplatin correlates with cellular arrest in the G2 phase of the cell cycle.Drug Administration Schedule: Time schedule for administration of a drug in order to achieve optimum effectiveness and convenience.Treatment Outcome: Evaluation undertaken to assess the results or consequences of management and procedures used in combating disease in order to determine the efficacy, effectiveness, safety, and practicability of these interventions in individual cases or series.Antineoplastic Combined Chemotherapy Protocols: The use of two or more chemicals simultaneously or sequentially in the drug therapy of neoplasms. The drugs need not be in the same dosage form.Dose-Response Relationship, Drug: The relationship between the dose of an administered drug and the response of the organism to the drug.Prospective Studies: Observation of a population for a sufficient number of persons over a sufficient number of years to generate incidence or mortality rates subsequent to the selection of the study group.
