Background/Objectives: Home blood pressure monitoring (HBPM) is increasingly used in pregnancy, but evidence regarding its safety and clinical utility in women with hypertensive disorders of pregnancy (HDPs) remains limited. We aimed to compare maternal and fetal outcomes and healthcare use with HBPM versus clinic-based blood pressure monitoring. Methods: Cochrane, MEDLINE, Embase and PubMed were searched for randomized controlled trials published from January 1970 to December 2022; this review was undertaken to inform guideline development of hypertension in pregnancy in Australia and New Zealand. Two reviewers independently screened studies, extracted data and assessed risk of bias using RoB. Outcomes reported by at least two clinically comparable trials were pooled and heterogeneity was summarized using I2. Outcomes reported by a single trial are presented as individual study estimates and were not meta-analyzed. Certainty of evidence was assessed using GRADE. Results: Four randomized trials involving 3533 participants were included. HBPM was not associated with a statistically significant difference in preeclampsia, adverse maternal composite outcomes, severe hypertension (≥160/110 mmHg), emergency delivery for hypertension, stillbirth, small-for-gestational-age birth or neonatal mortality. A single trial also found no statistically significant difference in preterm birth before 34 weeks. Serious fetal outcomes were uncommon and confidence intervals were wide. In one pilot trial, HBPM was associated with fewer antenatal visits and a longer duration of blood pressure monitoring. Conclusions: In structured care pathways with clinician oversight and predefined escalation protocols, HBPM was not associated with evidence of increased maternal or fetal risk and may be a useful adjunct to standard antenatal care. The small number of United Kingdom trials, sparse serious events and limited evidence in established or severe preeclampsia preclude conclusions of equivalence or definitive safety.

Hypertension III: Clinical Manifestations and Diagnostic Studies

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Hypertension V: Nursing Management

The nursing management of hypertension involves accurately assessing symptoms, making a comprehensive nursing diagnosis, collaborating with patients to set goals, and implementing targeted interventions to mitigate the condition's impact and improve patient well-being.Comprehensive AssessmentThe initial step in nursing care for hypertension involves a thorough patient assessment. It includes evaluating symptoms such as headaches, dizziness, blurred vision, and previous hypertension episodes.
Special considerations while measuring blood pressure01:28

Special considerations while measuring blood pressure

When assessing blood pressure (BP), healthcare professionals must consider various factors and potential unexpected outcomes to ensure accurate readings and provide proper patient care. Adhering to these guidelines is essential to achieving the most reliable results.
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.

Errors occurring during blood pressure monitoring

Blood pressure monitoring is a crucial clinical procedure in diagnosing and managing various cardiovascular conditions. Despite its significance, the accuracy of blood pressure measurements can be compromised by multiple factors, potentially leading to either falsely high or low readings. These inaccuracies are critical as they can significantly impact patient care. So, it is vital to understand these challenges deeply and adopt strategic approaches to minimize errors.

Pre-Procedural Guidelines for Assessing Blood Pressure

Accurate blood pressure assessment is crucial for diagnosing and managing various health conditions. To ensure the reliability of these measurements, healthcare professionals must adhere to standardized pre-procedural guidelines. These guidelines enhance patient safety and improve the overall quality of healthcare. The following steps are essential for obtaining accurate and consistent blood pressure readings, from using the appropriate tools to ensuring effective communication with the patient.

Assessment of blood pressure in brachial artery(two-step method)

Measuring blood pressure is a fundamental skill in healthcare that aids in diagnosing and monitoring hypertension and other cardiovascular conditions. An aneroid sphygmomanometer, commonly used in clinical settings, offers a manual and precise method for blood pressure measurement. The technique for using this instrument involves specific steps that must be carefully executed to ensure accuracy. The following detailed description outlines a two-step technique for assessing blood pressure using...
