What side effects are associated with this type of intervention?

General anesthesia can lead to several side effects, particularly affecting cardiovascular function. Common side effects include hypotension (low blood pressure), bradycardia (slow heart rate), and sedation. In some cases, prolonged neuromuscular weakness and respiratory complications such as bronchoconstriction may occur. These effects necessitate careful monitoring, especially in patients with pre-existing conditions.

What prior FDA approvals exist?

FDA-approved treatments for managing cardiovascular function and hypotension during anesthesia include esmolol, an ultra-short-acting beta-blocker, and vasopressors like norepinephrine and vasopressin. These drugs are used to maintain hemodynamic stability and manage hypotension in patients undergoing general anesthesia.

What other types of research exist?

Promising alternatives to general anesthesia that minimize cardiovascular effects, including hypotension, include neuraxial anesthesia (epidural or spinal anesthesia) and regional anesthesia (e.g., brachial plexus block). Sedation techniques using agents like midazolam or dexmedetomidine, which offer a more stable hemodynamic profile, are also viable options.

Summary

This trial studies how general anesthesia affects heart function and blood flow in people who experience low blood pressure during surgery.

Who is the study for?

This trial is for adults over 18 who need general anesthesia for surgery, with at least a 20-minute prep time before incision and normal blood pressure. It's not for those in emergency surgery, on anti-hypertensive or beta-blocker medications, or with a history of heart disease.

What is being tested?

The study uses echocardiography to observe how general anesthesia affects heart function and blood flow during surgery, especially when patients have low blood pressure after receiving anesthesia.

What are the potential side effects?

Since the intervention being studied is an observational technique (echocardiography), there are no direct side effects from it. However, risks may be associated with the underlying surgical procedure and use of anesthesia.

Mechanism Of Action

Side Effect Profile

Other Research

General anesthesia involves the use of inhalational agents (such as sevoflurane) and intravenous agents (such as propofol) that depress the central nervous system, leading to loss of consciousness and sensation. These agents cause vasodilation and myocardial depression, resulting in decreased systemic vascular resistance and cardiac output, which can lead to hypotension. This understanding is crucial for anesthesia patients because managing blood pressure is essential to ensure adequate organ perfusion and prevent complications during surgery.
