Since a high blood pressure could exacerbate the tear in the aorta or even separate it completely from the heart, which would almost inevitably kill the patient, hospital staff take measures to keep a patient's blood pressure low.  Such measures include giving pain medication, administration of beta blockers, keeping the patient calm, and avoiding procedures that could cause gagging or vomiting.
