One of the seniors in our ward was so furious. He was apparently scolded by our headnurse during the grand endorsement. As the outgoing nurse, he needs to endorse all the patients to the incoming nurses and that includes the headnurse.
Our patient was a 22-year-old female who was diagnosed to have Ventricular Septal Defect or VSD who came in due to complaint of fatigability. VSD is a congenital disease or present at birth and is characterized by a hole or a shunt in the lower chambers (right and left) of the heart.
Anatomically, the blood flows from the superior and inferior vena cava to right atrium down to the right ventricle going to the pulmonary artery to the lungs for oxygenation then to the pulmonary vein to the left atrium down to the left ventricle then pumped out to the systemic circulation. With the VSD, the oxygenated blood coming from the left atrium leaks back to the right ventricle which mixing with unoxygenated blood then goes back to the lungs that cause too much blood pressure in the lungs that causes pulmonary hypertension. Also, the shunt allows for the poorly oxygenated blood to enter the left ventricle that causes the blood to circulate the system.
Our female patient was diagnosed to have Eisenmenger Syndrome which is associated with the high blood pressure in the lungs or the pulmonary hypertension caused by the VSD. The mean pulmonary artery pressure (mPAP) is ≥25 mmHg at rest or ≥30 mmHg with exercise (Barst et al 2004).
Eisenmenger’s Syndromes signs and symptoms include:
• Abnormal heart rhythm (arrhythmia)
• Bluish lips, fingers, toes, and skin (cyanosis)
• Chest pain
• Coughing up blood
• Dizziness
• Fainting
• Feeling tired
• Shortness of breath
• Stroke
• Swelling in the joints caused by too much uric acid (gout)
Complete blood count revealed increased levels which is common presentation of the syndrome. She underwent phlebotomy. Older children with symptoms may have blood removed from the body (phlebotomy) to reduce the number of red blood cells, and then receive fluids to replace the lost blood (volume replacement).
Heart murmur or an abnormal heart sound can also be heard and this was among the questions of our headnurse. I do not know but based on the feedback I received from my co-staff nurses, what our headnurse did was a bit out of bounds. The senior nurse felt belittled. It is one thing that she knows something that we do not know but it is another to guide us to learning the ropes of cardiac nursing.
Searching the internet, I landed on kidshealth.org. A heart murmur is a whooshing sound between the beats that a doctor hears through a stethoscope. The whoosh is just an extra noise that the blood makes as it flows through the heart. Normal heart sounds are called “lub-dub”.
The heart makes a “lub” sound with the closing of the valves that control blood flow from the upper chambers to the lower chambers. Then, as the valves controlling blood going out of the heart close, you will hear the sound “dub.”
Murmurs have grades. Grade 1 is the softest-sounding murmur, and Grade 6 is the loudest. A murmur graded 4, 5, or 6 is so loud you can actually feel a rumbling from it under the skin if you put your hand on the person’s chest.
There is no treatment for this type of condition and the treatment is palliative or based on the presenting complication. The pulmonary hypertension may be treated with prostacyclin and endothelin antagonists.
Viagra, which is the common form of Sildenafil is used to treat pulmonary hypertension that helps dilate the pulmonary arteries.
Prophylaxis against endocarditis is also recommended. Once developed, life expectancy for patients with Eisenmenger Syndrome depends on the type and severity of the underlying defect and right ventricular function, and ranges from 20 to 50 years.
According to Mayoclinic. Com, doctors do not recommended surgery once Eisenmenger syndrome has been developed although some may benefit from heart and lung transplantation or lung transplant with repair of the hole in the heart.
Next time that our headnurse will throw a big stone of a question at us, I will make sure that I have my armor.
