What is the initial response when a patient experiences severe chest pain in the dental chair?

When a patient experiences severe chest pain in the dental chair, the initial response should be to administer glycerine trinitrate and monitor the patient in an upright position. Glycerine trinitrate, or nitroglycerin, is a medication commonly used to relieve angina and can help improve blood flow to the heart by dilating blood vessels. This is critical in a dental setting, as dentists and hygienists are not typically equipped to perform a comprehensive emergency response.

Monitoring the patient in an upright position can also be beneficial, as it may help reduce strain on the heart and improve respiratory function. This approach prioritizes the patient's immediate comfort and addresses potential cardiovascular complications.

Other options such as waiting for confirmation of a myocardial infarction or simply checking the patient's radial pulse may delay necessary intervention. It's essential to take immediate action when a patient presents with chest pain, as this could indicate a life-threatening condition like a heart attack, and timely treatment can be crucial for their prognosis.
