Prevention and Management of Acute or Delayed Nausea and Vomiting The only class of medication that has shown benefit in some studies is benzodiazepines, most commonly lorazepam. Most antiemetics have not shown benefit for the treatment of ANV, but their use during chemotherapy may have a dramatic effect in decreasing the incidence of ANV.

However, physicians and nurses underestimate the incidence of chemotherapy-induced N&V.Ĭlearly, the most important aspect of ANV is prevention of acute and delayed N&V associated with chemotherapy. TheĮarlier ANV is identified, the more likely treatment will be effective, so early screening and referral are essential.

Working with cancer patients should be considered when ANV is identified. Other mental health professional with specific training and experience in The most and should be considered as treatment. With guided imagery, hypnosis, and systematic desensitization has been studied One experimental study, it was shown that a novel beverage could become aĬonditioned stimulus to nausea when paired with several chemotherapyĭistraction via the use of video games. Increasing as patients get closer to the time of their infusion. Also, most studies have found (1) a higher probability of ANV withĪn increasing number of chemotherapy infusions, and (2) the intensity of ANV Rare, and few patients ever experience ANV without previous postchemotherapy For example, the prevalence of ANV before treatment with any chemotherapy is Variety of correlational studies provide empirical support for classicalĬonditioning. Other life situations (e.g., food poisoning), results in adaptive avoidance. Is not an indication of psychopathology but is rather a learned response that, in These previously neutral stimuli thenīecome conditioned stimuli and elicit ANV in future chemotherapy cycles. Presence of the oncology nurse, chemotherapy room). The drugs are paired withĪ variety of other neutral, environmental stimuli (e.g., smells of the setting, Postchemotherapy nausea and vomiting (N&V) in some patients. The chemotherapy drugs are the unconditioned stimuli that elicit InĬancer chemotherapy, the first few chemotherapy infusions are the learning Response (e.g., ANV) after a number of pairings or learning trials. (e.g., smells of the chemotherapy environment) elicits a conditioned In classical conditioning, a previously neutral stimulus Although other theoretical mechanisms have been proposed, ANV appears to beīest explained by classical conditioning, also known as Pavlovian or respondentĬonditioning.
