Here is a quick mnemonic “NAUSEA VOMITING“ to remember about Nausea & Vomiting
This can be valuable for patients as well as medical doctors, nurses & students doing their clinical rounds. You can also find it very useful for med exams like USMLE, NExT Medical Step 1&2, MBBS, NEET PG, INI-CET, FMGE,MCAT & NCLEX exams
Nausea & Vomiting : How To Remember Easily ?
- N – Neurotransmitters: Labyrinthine disorders stimulate vestibular muscarinic M1 and histaminergic H1 receptors.
- A – Activators of Emesis: Emetic stimuli act at several sites. Emesis evoked by unpleasant thoughts or smells originates in the brain.
- U – Underlying Mechanisms: Mechanisms underlying nausea are poorly understood but likely involve the cerebral cortex.
- S – Somatic and Visceral Muscles: Somatic and visceral muscles respond stereotypically during emesis.
- E – Emesis Coordination: Coordination of emesis involves brainstem nuclei and various pathways.
- A – Area Postrema: The area postrema, in the medulla, responds to bloodborne stimuli and is termed the chemoreceptor trigger zone.
- V – Vagal Afferent Stimuli: Vagal afferent stimuli activate 5-HT3 receptors.
- O – Oral Propagating Spikes: Slow waves are abolished during emesis and replaced by orally propagating spikes.
- M – Motion Sickness: Motion sickness and inner ear disorders act on labyrinthine pathways.
- I – Insula and Amygdala: Functional brain imaging studies show activation of cerebral regions, including the insula and amygdala, during nausea.
- T – Therapies for Vomiting: Therapies for vomiting act on specific receptor-mediated pathways.
- I – Involvement of CNS: NK1 receptors in the central nervous system mediate both nausea and vomiting.
- N – Nuclei Coordination: Brainstem nuclei coordinate the initiation of emesis involving various pathways.
- G – Gastric Irritants: Gastric irritants and cytotoxic agents stimulate gastro-duodenal vagal afferent nerves.
