Summary
Beta-blocker (β) use before surgery needs more research. Continue beta-blockers for existing patients, titrating dosage to heart rate and blood pressure, especially for high-risk cardiac patients.
Area of Science:
- Cardiology
- Anesthesiology
- Pharmacology
Background:
- The role of preoperative beta-blockade in surgical patients has evolved.
- Evidence from large, randomized controlled trials is needed to guide practice.
- Current guidelines suggest a careful approach to perioperative beta-blocker use.
Purpose of the Study:
- To review the current evidence and recommendations for perioperative beta-blocker management.
- To provide guidance on the judicious use of beta-blockers in patients undergoing surgery.
Main Methods:
- Review of existing literature and clinical trial data on beta-blocker use in the perioperative period.
- Analysis of current guidelines and expert consensus on the topic.
Main Results:
- Continuation of beta-blockers is recommended for patients already taking them prior to surgery.
- For patients undergoing major colorectal surgery or those with coronary artery disease or high cardiac risk, beta-blockers should be titrated to heart rate and blood pressure.
- Initiation of beta-blockers, when indicated, should occur weeks before surgical procedures.
Conclusions:
- A personalized and titrated approach to perioperative beta-blockade is currently supported.
- Fixed, long-acting dosages are less recommended than titrated regimens.
- Further large-scale randomized controlled trials are necessary to definitively establish optimal perioperative beta-blocker strategies.

β receptors are classified into three subclasses: β1, β2, and β3. β1 receptors are primarily located in the heart and kidneys. When they get activated, they increase heart rate, contractility, and renin release. This process enhances blood pressure and aids in stress management. In contrast, β2 receptors are situated mainly in the lungs, blood vessels, and skeletal muscles. Upon activation, they trigger smooth muscle relaxation, causing bronchodilation and...

Third-generation β-blockers, such as labetalol and carvedilol, represent a significant advancement in managing cardiovascular conditions. Unlike conventional β-blockers, which can induce peripheral vasoconstriction, third-generation drugs block α1 adrenoceptors. This promotes vasodilation through several mechanisms, such as increased nitric oxide production, inhibition of calcium ion entry, opening of potassium ion channels, and antioxidant action. Labetalol, for instance, is...

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...

Depolarizing blockers are administered through intravenous injection. Succinylcholine is the most common choice of depolarizing blockers in emergency clinical practices. Although they have a rapid onset, they readily diffuse away from the motor end plate into the extracellular fluid. They are metabolized by enzymes such as liver butyrylcholinesterase and plasma pseudocholinesterases. This produces a short duration of action, typically 5-10 minutes long, unlike nondepolarizing blockers, which...

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

01:22Heart Failure Drugs: β-Blockers
2.7K
β-adrenergic antagonists, commonly known as β-blockers, block the effects of sympathetic neurotransmitters such as noradrenaline (NA) and adrenaline (ADR). They have several beneficial effects in heart failure treatment. They reduce heart rate, the force of contraction, and cardiac muscle relaxation. They also slow the atrial-ventricular conduction rate and raise the threshold for arrhythmias. The concentration of β-blockers determines their effects on bronchodilation,...
