Pro-Emetic Receptors
receptor stimulation by acteylcholine (proemetic neurotransitter) evokes emesis
Serotonin (5HT3)
•receptor (located in the brainstem) stimulation by vestibular hyperactivity triggers activation of histaminergic neuronal system, evoking emesis
Acetylcholine (M1)
activation leads to release of emetic neurotransmitters and/or peptides (dopamine, cholecystokinin, glutamate, acetylcholine, substance P, 5-HT)
Histamine (H1)
receptor stimulation by substance P excites neurons in the area postrema evokes emesis
Dopamine (D2/3)
receptor (loacted throughout the dorsal vagal, vagal nerves, and GI tract) stimulation by various stimuli evokes emesis
Substance P Neurokinin NK1 (NK1R)

Emma is recovering from surgery and her doctor decides to use opioid-sparing analgesic techniques for her pain management. This approach has no impact on Emma's risk of experiencing postoperative nausea and vomiting (PONV).
FALSE
TRUE
TRUE/FALSE
Samuel, a patient scheduled for surgery, is concerned about postoperative nausea and vomiting (PONV). His doctor decides to administer 5-HT3 antagonists as part of his care plan. This is an effective measure to reduce the risk of PONV.

FALSE
TRUE
TRUE/FALSE
