Singing Can Lower Blood Pressure Before Surgery


singing reduce blood pressureAnxiety and tension usually attacks patients who will perform a surgery. The anxiety triggers increased blood pressure. But with singing an elderly patient is able to control nervousness and manage to lower blood pressure.

Doctors report that singing can lower blood pressure of a woman with 76 years of age who experience severe hypertension prior to total knee replacement surgery for osteoarthritis (OA).

Patient’s blood pressure rises initially and could not be relieved by medication, but suddenly the patient’s blood pressure dropped dramatically when they sang some religious songs.

The case report have been published in the ‘Arthritis Care & Research journal’ April 2011 issue. Arthritis Care & Research is a journal published by Wiley Blackwell on behalf of the American College of Rheumatology (ACR).

The doctors said that the standard therapy for hypertension involves drugs based preoperative therapy including diuretics, beta blockers, calcium channel blockers, and angiotensin converting enzyme (ACE) inhibitors.

The drugs used to lower blood pressure to the acceptable levels for the operation. However, some patients do not respond to treatment. In patients who are unresponsive to standard therapies, alternative hypertension interventions is necessary.

“Some studies show that listening to music can be effective to reduce blood pressure by calming or distracting the patient before surgery. It can reduce stress and anxiety. Our case study expands on medical evidence to show that singing also has potential therapeutic effects in the setting of pre-operation, “explains lead author Nina Niu, a researcher from Harvard Medical School in Boston, according to Epharmapedia .

The research subjects in this case are woman 76 years old from the Dominican Republic with hypertension and has a 15-year history of bilateral knee OA. Patient was treated with ACE inhibitors and calcium channel blockers for high blood pressure and diclofenac, which is a non-steroidal anti-inflammatory (NSAIDs) for knee pain.

Upon admission to the hospital for surgery, the patient’s blood pressure was 160/90 mm Hg, has been taking the drug with nifedipine and lisinopril. Then the woman’s blood pressure rose to 240/120 mm Hg and settled, so doctors consider delaying surgery. But the medical team at Dominican Hospital has a limited time. Thus it is very important that the patient’s blood pressure is reduced so that operation can be performed.

The patient asked the doctor if she could sing. The patient said that she often sang to calm down and to help sleep. Then the medical team allowed the patient to sing.

After singing two songs, her blood pressure had dropped to 180/90 mm Hg. By continuing to sing for 20 minutes, the patient’s blood pressure is lower and persisted for several hours afterward.

As instructed by physicians, the patient sang periodically during one night that can continue to lower her blood pressure at acceptable levels. The next morning, the patient’s blood pressure is normal enough to do a knee replacement surgery. The operation was successful and without complications.
