Insights

Managing blood pressure in pediatric patients with pheochromocytomas and paragangliomas (PPGL) is challenging. Selective alpha-blockers and calcium channel blockers are increasingly used for perioperative care due to better safety and availability.

Area of Science:

  • Pediatric Endocrinology
  • Cardiovascular Pharmacology
  • Oncology

Background:

  • Pheochromocytomas and paragangliomas (PPGL) are rare tumors causing secondary hypertension in children.
  • Perioperative blood pressure management in pediatric patients with PPGL is a significant clinical challenge.

Purpose of the Study:

  • To review antihypertensive treatment options for pediatric patients with PPGL.
  • To focus on recent literature regarding perioperative blood pressure management in this population.

Main Methods:

  • Literature review focusing on studies from the past several years.
  • Analysis of case series and single-center experiences for treatment guidelines.

Main Results:

  • Phenoxybenzamine, selective α1-blockers (e.g., doxazosin), and calcium channel blockers have been used successfully.
  • Current pediatric practice and international guidelines support preoperative α-adrenergic blockade.
  • Selective α1-blockers and calcium channel blockers are gaining favor over phenoxybenzamine due to cost, availability, and side effect profiles.

Conclusions:

  • Selective α1-blockers and calcium channel blockers represent viable and often preferred alternatives to phenoxybenzamine for perioperative management of pediatric PPGL.
  • Continued adherence to preoperative α-adrenergic blockade is recommended for optimal patient outcomes in pediatric PPGL management.

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.

Adrenergic Antagonists: Pharmacological Actions of β-Receptor Blockers

β-receptor blockers significantly impact the cardiovascular system by counteracting catecholamine-induced sympathetic responses. These medications decrease heart rate, contractility, and cardiac output, potentially leading to cardiac depression, life-threatening bradycardia, and death. Therapeutically, β-blockers function as mild antihypertensives and are utilized in treating angina pectoris and cardiac arrhythmias. However, nonselective β-blockers inhibit β2-receptors in...

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers

Receptor tyrosine kinase inhibitors (TKIs) and calcium channel blockers (CCBs) are two critical categories of drugs employed in the treatment of pulmonary artery hypertension (PAH). PAH is a disease that causes high blood pressure in the pulmonary arteries, resulting in chest pain, fatigue, and shortness of breath.
TKIs, such as imatinib (Gleevec), are particularly effective in tackling the growth and mitogenic factors that become upregulated in PAH patients. These factors contribute to the...

Hypertension and Regulation of Blood Pressure01:18

Hypertension and Regulation of Blood Pressure

Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...

Adrenergic Agonists: Therapeutic Uses

Adrenergic agonists have diverse therapeutic uses across various medical conditions and emergencies.
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

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...
