Episode notes
Broad Causes of Nausea and Vomiting
- Nausea and vomiting have diverse causes including medications, metabolic, gastrointestinal, and neurological origins.
- Knowing the cause is critical because different pathways require targeted treatments affecting receptor selection.
Evaluate Severe Nausea Thoroughly
- Evaluate patients with disproportionate or unexplained nausea and vomiting carefully.
- Use a thorough neuro and abdominal exam including bedside ultrasound to assess gastric and bowel function.
Use Targeted Imaging and Ultrasound
- Use optic nerve sheath ultrasound as a screening tool for raised intracranial pressure.
- Imaging including abdominal x-ray or head CT should be guided by clinical suspicion, never routine.
