Summary
Beta-blockade effectively controls heart rate (HR) before and during surgery. Postoperative HR requires attention to sustain the full benefits of beta-blockade therapy for patients undergoing noncardiac procedures.
Area of Science:
- Cardiology
- Anesthesiology
- Perioperative Medicine
Background:
- Perioperative beta-blockade is a standard practice for cardiac risk management.
- Assessing heart rate (HR) control during the perioperative period is crucial for patient outcomes.
Purpose of the Study:
- To evaluate the effectiveness of beta-blockade in controlling heart rate (HR) preoperatively, intraoperatively, and postoperatively.
- To determine if beta-blockade recommendations during preoperative clearance translate to adequate HR management.
Main Methods:
- Retrospective review of 130 patients undergoing noncardiac surgery with recommended beta-blockade.
- Data collected included demographic information and comorbid risk factors.
- Statistical analysis using chi-square test and analysis of variance.
Main Results:
- Mean preoperative HR was 74 bpm, intraoperative HR was 69 bpm, and postoperative HR was 84 bpm.
- Significant differences were observed between preoperative/intraoperative and postoperative HR (P < .003).
- Perioperative cardiac morbidity was 5.4%, with no 30-day mortality.
Conclusions:
- Beta-blockade demonstrates sufficient heart rate (HR) control in the preoperative and intraoperative phases.
- Postoperative heart rate (HR) management warrants careful consideration to optimize the benefits of beta-blockade.

01:22Heart Failure Drugs: β-Blockers
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, vasodilation, and...
01:28Cardiomyopathy VII: Pre and Post Operative Nursing Management
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...
01:27Adrenergic 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 bronchial smooth...
01:24Antiarrhythmic Drugs: Class II Agents as β-Adrenergic Blockers
Adrenergic stimulation generally impacts cardiac rate and rhythm. Specifically, stimulation of the β-adrenoceptors triggers an increase in intracellular calcium ion influx and pacemaker currents, which may cause arrhythmias. Catecholamines like adrenaline also demonstrate β2-adrenoceptor-mediated hypokalemia, impacting cardiac action potential and disrupting the normal cardiac rhythm. Class II antiarrhythmic drugs are β-adrenoceptor antagonists or β-blockers, which indirectly block calcium...
01:31Adrenergic Antagonists: ɑ and β-Receptor Blockers
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 clinically...
01:28Antihypertensive Drugs: Types of β-Blockers
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 vasodilation. This widens airways and...
