Ramipril is a newly synthesized angiotensin converting enzyme inhibitor without a sulfhydryl group in the molecule but with a prolonged duration of action. Efficacy, tolerance and safety of this drug were evaluated in 10 patients with severe essential hypertension. After a treatment period of at least 4 weeks with the conventional antihypertensive drug combination of a diuretic and a beta-blocking agent with the vasodilator dihydralazine, their systolic and diastolic blood pressures averaged 161 +/- 6 and 111 +/- 2 mm Hg, respectively. Because diastolic blood pressure during this drug regimen was still greater than 105 mm Hg in all patients, the patients received ramipril initially at single daily doses of 5 mg in addition to their previous medication. The first dose of 5 mg ramipril resulted in a moderate but significant decrease in systolic and diastolic blood pressure in 9 of the 10 patients to 142 +/- 5 and 104 +/- 4 mm Hg (p less than 0.01), respectively, between 3 and 6 hours after drug administration. In 1 patient blood pressure was unresponsive to ramipril and 1 patient complained of nausea and vomiting within the first week of treatment with ramipril. Within the following 8-week treatment period with a once-daily intake of 5 or, if necessary, 10 mg of ramipril, diastolic blood pressure normalized in the remaining 8 patients to less than 90 mm Hg. Systolic and diastolic blood pressure averaged 130 +/- 5 and 83 +/- 2 mm Hg, respectively, at the end of the 8-week treatment period with ramipril. Severe hypotension and reflex tachycardia were not observed.(ABSTRACT TRUNCATED AT 250 WORDS)

1 Among 34 patients with mild essential hypertension treated for four weeks with captopril alone the blood pressure of 47% returned to normal. By the end of the fourth week chlorthalidone had been added to captopril in 18 of the patients; 15 then achieved normal blood pressure, and only three failed to achieve diastolic blood pressures of under 100 mm Hg. 2 Among the 16 patients who continued to take captopril alone after the fourth week all achieved a return to normal blood pressure during the next 12 months of treatment. 3 Side effects of captopril were essentially limited to rash, taste alteration, and nausea and vomiting, which were usually mild and transient.

Perioperative hypertension is a phenomenon in which a surgical patient's blood pressure temporarily increases throughout the preoperative and postoperative periods and remains high until the patient's condition stabilizes. This phenomenon requires immediate treatment not only because it is observed in a majority of patients who are not diagnosed with high blood pressure, but also because occurs in patients with underlying essential hypertension who show a sharp increase in their blood pressure. The most common complication following facelift surgery is hematoma, and the most critical risk factor that causes hematoma is elevated systolic blood pressure. In general, a systolic blood pressure goal of <150 mm Hg and a diastolic blood pressure goal of >65 mm Hg are recommended. This article discusses the causes of increased blood pressure and the treatment methods for perioperative hypertension during the preoperative, intraoperative, and postoperative periods, in order to find ways to maintain normal blood pressure in patients during surgery. Further, in this paper, we review the causes of perioperative hypertension, such as anxiety, epinephrine, pain, and postoperative nausea and vomiting. The treatment methods for perioperative hypertension are analyzed according to the following 3 operative periods, with a review of the characteristics and interactions of each drug: preoperative antihypertensive medicine (atenolol, clonidine, and nifedipine), intraoperative intravenous (IV) hypnotics (propofol, midazolam, ketamine, and dexmedetomidine), and postoperative antiemetic medicine (metoclopramide and ondansetron). This article focuses on the knowledge necessary to safely apply local anesthesia with IV hypnotics during facelift surgery without the assistance of an anesthesiologist.
