Introduction
Pregnancy is a decisive and crucial phase in every expectant woman’s life. The gestation period exposes the expectant women to various disease conditions, which mandates periodic follow-ups and routine checkups. Underlying disease conditions during conception can pose pregnancy challenges and even threaten the baby in the womb. Perinatal management strategies often guide expectant mothers in tackling pregnancy-triggered health ailments. Expectant mothers are not supposed to consume all types of medications as they can potentially bring in toxicity and harm to the baby. Prompt therapeutic strategies are imperative to ensure the safety of both the expectant women and the baby in the womb.
What Is Hypertension?
Hypertension is a relatively common medical condition where the person experiences an appreciable enhancement in blood pressure. Blood pressure is the medical terminology that denotes the force or pressure expended by the bloodstream against the blood vessel’s wall. Ideal blood pressure is estimated to be within 120/80 millimeters of mercury. This pressure keeps the blood flow at a normal pace and flow. Any deviation from the normal range can bring health issues. A collapse in blood pressure compromises the blood flow, and many organs may be deprived of proper blood supply, typically the area above the heart level. Likewise, when the blood pressure surpasses the safe limit, it precipitates a medical condition called hypertension. Hypertension can potentially trigger the development of various cardiovascular complications and even stroke (impeded brain blood flow).
What Are the Hypertensive Disorders Encountered During Pregnancy?
Pregnancy-associated hike in blood pressure is a widely reported and routinely encountered condition. A spectrum of medical conditions falls under the broad category of pregnancy-associated hypertensive disorders. Specific study reports suggested that almost two to three percent of pregnancy complications are precipitated by hypertensive disorders in pregnant women, which draws the significance of these disease entities. Some of the routinely encountered hypertensive disorders in expectant women include the following conditions:
-
Chronic Hypertension: The enhanced blood pressure elicited before pregnancy or that is precipitated within the initial 20 weeks of the gestation period is categorized under chronic hypertension. Chronic hypertension may remain unresolved even after labor and childbirth. It accounts for around five percent of birth complications. Maternal age is an influential factor concerning chronic hypertension.
-
Preeclampsia: It is an alarming condition that an expectant woman elicits either post-20 weeks of gestation or post-childbirth. It encompasses enhanced blood pressure and impairment of some vital organ systems. Multi-organ involvement makes the condition grave and detrimental. Preeclampsia enhances the risk for maternal and fetal (baby in the womb) life. Early birth, placental rupture, low birth weight, and compromised growth are some of the fetal complications that can arise due to maternal preeclampsia. Stroke, impaired organ functions, and complications from blood clots within the blood vessels are the complications precipitated in pregnant women, further worsening the condition.
-
Gestational Hypertension: It is a peculiar form of hypertension triggered by altered hormonal status and dietary habits during pregnancy. This form of pregnancy-induced hypertension is mostly encountered in the later phase of pregnancy when expectant women cross the first 20 weeks of gestation. Gestational hypertension is reported in expectant women with no history of hypertensive issues in the pre-pregnancy or early pregnancy periods. In the majority of instances, gestational hypertension resolves within a period of 12 weeks following childbirth. Hence, it is considered to be transient hypertension. Gestational hypertension is closely associated with preeclampsia. Studies have revealed that gestational hypertension potentates the susceptibility for preeclampsia by 50 percent. Therefore, close surveillance of expectant women is imperative to keep track of blood pressure and advancing complications, if any.
-
Superimposed Preeclampsia: In this condition, expectant women diagnosed with chronic hypertension concurrently develop preeclampsia. Superimposed preeclampsia will potentiate chronic hypertension, which gives rise to enhanced susceptibility to hypertensive complications in expectant women.
What Are the Perinatal Management Strategies for Hypertensive Disorders in Pregnancy?
Hypertensive disorders in expectant women can enhance the likelihood of various birth complications in the maternal and fetal body. Prompt perinatal management is imperative to ensure the safety of pregnancy. The perinatal management strategies for chronic hypertension begin with periodic surveillance throughout the pregnancy. The blood pressure needs to be tackled and kept under the normal limit. Dietary modifications and pharmacological therapy are advised to reduce exaggerated blood pressure. Labetalol, Hydralazine, and Sodium nitroprusside are some antihypertensive medicines that are advisable for pregnant women.
Gestational hypertension necessitates a customized therapeutic regimen. Close surveillance of the expectant women’s blood pressure aids in detecting the condition at the earliest. Once detected, periodic gauging is essential to keep track of the advancing blood pressure and development of preeclampsia. Strategic planning of the delivery timing is made considering the severity of the preeclampsia. For milder cases, planned delivery is advised only after the baby attains more than 37 weeks of gestational growth. For severe preeclampsia cases, especially when the pregnancy is premature, the pregnant woman will be advised for hospital admission so that thorough monitoring and assessment can be exercised effectively.
For remote-term pregnancies, antenatal corticosteroid therapy is advised to encourage the maturation and development of the baby’s lungs within the womb. Severe preeclampsia often mandates early delivery of the baby much before the estimated date of delivery. Antenatal corticosteroids facilitate early maturation of the baby’s lung and thereby diminish the complexities associated with premature birth.
Pharmacological therapy using Magnesium sulfate aids in tackling preeclampsia events and associated premature placental break. The expectant women need to be stabilized and prepared before initiating labor. The risk concerning prematurity and preeclampsia will be considered before moving ahead with an immediate delivery option. Similarly, the patients should adhere to the medicine choice advised by the doctor as inadvertent changing of the medicine can impact the baby in the womb as all medicines are not considered safe during gestation.
Conclusion
Hypertensive disorders are a potent threat to successful pregnancy. However, advancements in surveillance and fetal monitoring techniques enable tackling the complications, leading to a favorable pregnancy outcome and safeguarding both the baby’s and mother’s lives. Perinatal management strategies like antenatal corticosteroid therapies facilitate the baby’s maturation and prepare them for delivery. The mode of delivery is determined considering other patient factors and anticipated complications.
Blood profile, urine analysis, ultrasonography, and fetal movements analysis are important determinants in assessing the safety of the baby and pregnant woman. In addition, post-childbirth, the mother needs to be monitored closely to ensure prompt resolution of the health complications precipitated during pregnancy. Enhanced medical care throughout the perinatal period warrants a favorable pregnancy experience and outcome for the expectant mother, even in hypertensive disorders.
