The cost of a laryngoscopy is about$200, but before the laryngoscopy, the patient needs to have blood tests, complete the four infections, and an electrocardiogram to determine if the patient has any infectious diseases and any heart problems. Patients also need to buy an anesthetic to contain in the mouth to reduce nausea during the laryngoscopy. The cost of the whole procedure is about$600, which may vary from hospital to hospital and from region to region. Patients may experience discomfort during the laryngoscopy, so family members are often required to accompany them. At the same time, patients should not eat or drink before the laryngoscopy to avoid nausea, vomiting and choking. Patients can drink and eat only two hours after the laryngoscopy. Normally, the results of the laryngoscopy can be taken away by the patient on the same day.
