Studies show that vasoconstrictors are used in about a fourth of all ICU admissions to manage dangerously low blood pressure [1.9.2]. This article answers 'What are examples of vasoconstrictors?' and details these critical drugs, from their mechanism to their diverse applications in medicine.

According to the Anesthesia Patient Safety Foundation, intraoperative hypotension—a significant drop in blood pressure during surgery—is a common phenomenon that is directly influenced by the use of general anesthesia. This effect is not a random occurrence but a predictable pharmacological response to the medications used, prompting anesthesiologists to meticulously manage blood pressure to ensure patient safety.

Intraoperative hypotension, or low blood pressure during surgery, occurs in 5% to 99% of patients under anesthesia, depending on the definition used [1.2.4]. But **does being under anesthesia lower your blood pressure** for everyone, and why does this happen?

Intraoperative hypotension, or low blood pressure during surgery, is a common occurrence, with incidence varying widely depending on the specific definition used. Understanding if and why **does your blood pressure go down under anesthesia** is crucial for anyone preparing for a surgical procedure, as this effect is central to anesthetic management and patient safety.

Approximately one-third of all intraoperative hypotensive episodes occur during the induction of anesthesia. The question of 'How does anesthesia affect blood pressure?' is a crucial topic for patient safety, as these medications can cause significant, though typically manageable, hemodynamic shifts during and after surgery.

Propofol is an intravenous anesthetic used to induce and maintain anesthesia in millions of procedures worldwide [1.2.1]. A critical question regarding its cardiovascular effects is: is propofol used for hypertension? The answer is a definitive no; in fact, it typically causes the opposite effect [1.3.1].

Low blood pressure, or hypotension, is a common and sometimes dangerous side effect of many medications. In older adults, in particular, drug-induced postural hypotension is a significant risk. This guide explains what medications will cause low blood pressure and what you should know to stay safe.

While vasodilation is a natural process vital for delivering oxygen and nutrients, extreme or uncontrolled widening of blood vessels can lead to serious adverse effects. Understanding what are the complications of vasodilation is crucial for both patients using vasodilator medications and healthcare providers managing related conditions.

The incidence of hypotension after spinal anesthesia can be as high as 64% in certain patient populations, like those undergoing cesarean sections [1.8.1]. While effective for pain management, a key question remains for clinicians: **Can local anesthetics cause hypotension?** The answer is yes, through various mechanisms.

While it is a common concern that pain medications can affect blood pressure, a review published in the *Journal of the American College of Cardiology* found that opioids can lead to hypotension and orthostatic hypotension. The relationship between an **analgesic** and blood pressure is complex and depends heavily on the specific drug, dosage, and patient's health status.
