You acn get the exam without sdation and with painkiller only (fentanyl
), but most gastros will insist on sedation
because it's easier and
them to do the exam; and
unfortunately they often treat the patient roughly because they know that the patient will have partial amnesia. The most common sedation drug Versed is linked to a lot of disturbing side effects; these occur after discharge, sometimes long after the exam and have been disabling in a lot of patients.
