What is the priority nursing intervention for a client with severe preeclampsia?
Preeclampsia and eclampsia are complications of pregnancy. The nurse plays a vital role in helping detect these conditions. Therefore, it’s important to know how to detect this condition in a pregnant patient. In this review you will learn about: Show
Lecture on Preeclampsia and EclampsiaPreeclampsia and Eclampsia Nursing Maternity ReviewWhat’s Preeclampsia? It’s a type of hypertensive disorder that occurs during pregnancy. It tends to occur after 20 weeks of gestation, which is the halfway point of a typical 40 week pregnancy. However, it’s important to note that this condition can present during the postpartum period (this is after delivery of the baby). Preeclampsia, if severe, can turn into a condition called eclampsia (note how similar their names are). Pre means “before” and eclampsia means “a convulsive state”, according to Merriam-Webster’s Dictionary (“Eclampsia Merriam-Webster”, n.d.). Therefore, eclampsia causes seizure activity, which can lead to coma and death. It is very important every pregnant patient is monitored for preeclampsia so it can be managed, which can help with the prevention of eclampsia in most cases. How Preeclampsia is Diagnosed?As the nurse it is important you’re aware of how this condition is diagnosed. This is because you will be responsible for collecting the information that helps diagnose preeclampsia and will report that abnormal information to the physician, who will make the diagnosis. So, what are the criteria for the patient to be diagnosed with this condition? The American College of Obstetricians and Gynecologists (ACOG) sets the guidelines for preeclampsia. The criteria are based on three things:
Blood Pressure Measurement: What is considered an elevated blood pressure for preeclampsia? At every prenatal visit a woman will have her blood pressure measured. With preeclampsia, the blood pressure is usually normal at the beginning of the pregnancy, but around 20 weeks gestation it starts to elevate. As the nurse, you want to watch out for the following measurements:
How is preeclampsia different than gestational hypertension? They’re both considered hypertensive disorders BUT gestational hypertension doesn’t cause injury to organs in the body or proteinuria, and this leads us to the next criteria. Results of Urine Sample At every prenatal visit a woman will have her urine assessed for protein and glucose (glucose measurement is important for detecting gestational diabetes). What is considered proteinuria for preeclampsia?
Signs and Symptoms of Organ Injury The liver, brain, and kidneys tend to be affected the most with preeclampsia. We will discuss more about this in the pathophysiology section, which will correlate with the signs and symptoms you will see in the patient. RECAP: You’re assessing for new onset of hypertension (>140/90…most likely to start occurring at 20 weeks and onward), protein in the urine “proteinuria”, signs and symptoms of organ injury. Risk Factors for Preeclampsia
Pathophysiology of PreeclampsiaTo help us understand the signs and symptoms of preeclampsia, we are going to mesh the pathophysiology with the signs and symptoms. Because if you can understand what is going on in mom’s body, the signs and symptoms make so much sense and you don’t have to memorize them. Key Players of Preeclampsia:
The spiral arteries of the uterus play an important role in providing blood flow to the growing placenta and baby. Normally during pregnancy, the spiral arteries within the uterus widen in diameter to help increase blood flow to the placenta, which is very vital as the pregnancy progresses and baby requires more nutrients and oxygen. This widening of the spiral arteries is thought to be influenced by how well the trophoblast burrowed into the uterus during early pregnancy. If the trophoblast failed to do this properly, the spiral arteries stay narrow and fail to widen as the pregnancy progresses, which will cause an ischemic placenta (the placenta is deprived of oxygen-rich blood flow it needs to flourish and grow). The oxygen deprived placenta does not like this and becomes stressed out so it releases substances into mom’s circulation in hopes of increasing blood flow to it. However, these substances are very toxic to mom’s endothelial cells. What are endothelial cells, where do they live, and what do they do? These cells can be found lining the inside of blood vessels throughout the body and organs. Two functions they perform: Give tone to the vessels (contraction and dilation of the vessel) and have a role with vessel permeability When endothelial cells are exposed to the toxic substances by the placenta they become damaged and do not work properly. This is where we start to see the signs and symptoms of preeclampsia (they really stem from the damaged endothelial cells). The damaged endothelial cells fail to function properly and cause:
Signs and Symptoms of Preeclampsia Hypertension: damaged endothelial cells lose their tone, therefore, vasospasm (contraction of the vessel) starts to occur and this leads to increase pressure within the vessel…hence causes hypertension Proteinuria: this is due to kidney injury…the kidneys are being deprived of proper blood flow and endothelial cells that line the glomerulus (this structure filters the blood and it normally does NOT filter large molecules like protein) are damaged. The damaged cells of the glomerulus start to leak protein from the blood into the urine causing proteinuria. Note: this also drops protein levels in the blood (why the woman needs a protein-rich diet)
Edema (eyes, face, extremities, pulmonary edema, increase weight gain, cerebral edema): the increase in permeability of the endothelial cells causes protein to escape the vessel. Remember protein helps regulate oncotic pressure…so where protein goes, so does water. Therefore, water will leave the intravascular area and shift to the interstitial tissue and cause swelling. This further complicates things because it decreases blood volume. So, there is less blood volume being used to perfusion the organs and this cause further organ injury.
Upper abdominal pain and increase in liver enzymes (AST and ALT): the liver is affected due to decrease perfusion and swelling Decreased platelets (leading the DIC), hemolysis (rupture of red blood cells)…leading to HELLP Syndrome: the damaged endothelial cells cause red blood cells to rupture and it causes the body to want to repair the cells…so platelets start to congregate at these cells (note in severe cases there are many damaged endothelial cells in the body so that requires a lot of platelets)…this depletes the platelet stores and cause micro-clot development with the vessels, which decreases perfusion even more. NOTE: Preeclampsia varies in how severe it gets…some women have mild cases while others have severe cases that progress to seizures and/or coma and the complications below. Severe preeclampsia condition can lead to:
Nursing Interventions for Preeclampsia & TreatmentTo help us take everything we learned about the patho and signs and symptoms and incorporate it with the nursing interventions and treatment, let’s remember the word: “PREECLAMPSIA” Proteinuria monitoring: check urine for protein at every prenatal visit (some women may be taught to do this at home with a dipstick test):
Reflexes hyperactive (deep tendon reflexes…patellar and bicep)
Evaluate blood pressure for hypertension: monitored at every prenatal visit and educate mother to monitor at home
Edema monitoring (watch for and educate mother about this):
Calcium gluconate: antidote for magnesium sulfate toxicity…be sure to have it handy Left side-lying position (helps prevent placenta ischemia and increases blood flow to baby), bed rest/limit stimulation, fetal heart rate monitoring (report decrease in fetal activity) Assess for seizure activity “eclampsia”: there is a risk during and after labor (up to 48 hours)
Magnesium sulfate administered to prevent seizures during and after labor (risk for seizures up to 48 hours after delivery)
Protein-rich diet (remember there may be low protein in blood due to proteinuria…protein leaks into the urine and leaves blood)
Severe complications to watch for:
I & Os: strict monitoring (may need Foley catheter), abnormal sign: low urinary output less than 30 cc/hr (kidneys aren’t being perfused very well) Antihypertensives (labetalol, hydralazine)
