Anesthetists

Area of Science:

  • Anesthesiology
  • Critical Care Medicine

Background:

  • Intraoperative hypotension (IOH) is a common concern during anesthesia.
  • Existing definitions of IOH vary, impacting clinical decision-making.
  • The relationship between IOH definitions and antihypotensive medication (AHM) administration requires clarification.

Purpose of the Study:

  • To evaluate the association between common IOH definitions and anesthetists' AHM use.
  • To compare the predictive accuracy of existing IOH definitions for AHM administration.
  • To identify factors influencing anesthetists' decisions regarding IOH management.

Main Methods:

  • Observational study of 2350 patients undergoing mixed surgical procedures.
  • Analysis of three standard definitions of IOH based on systolic blood pressure (SBP) thresholds and percentage fall.
  • Comparison of prediction accuracy for AHM use and multivariate logistic analysis of associated factors.

Main Results:

  • Existing IOH definitions showed moderate accuracy (54-67%) in predicting AHM use.
  • A novel definition (SBP < 92 mmHg or > 24% fall) demonstrated slightly improved prediction (68%).
  • IOH, by any definition, was not significantly associated with postoperative inpatient stay.

Conclusions:

  • Current IOH definitions have limited correlation with anesthetists' clinical judgment for AHM administration.
  • Anesthetists consider multiple perioperative factors beyond SBP when managing IOH.
  • Patient age, physical status, and surgical characteristics better predict postoperative stay than IOH itself.

Alterations in Blood Pressure01:30

Alterations in Blood Pressure

Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart beats)...

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...
Blood Pressure Imbalances and Circulatory Shock01:24

Blood Pressure Imbalances and Circulatory Shock

Disorders affecting blood volume, vascular tone, or vascular function can disrupt vascular homeostasis, including conditions like hypertension, hemorrhage, and shock.
Blood Pressure: Hypertension and Hypotension
Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...
Pre-Procedural Guidelines for Assessing Blood Pressure01:10

Pre-Procedural Guidelines for Assessing Blood Pressure

Accurate blood pressure assessment is crucial for diagnosing and managing various health conditions. To ensure the reliability of these measurements, healthcare professionals must adhere to standardized pre-procedural guidelines. These guidelines enhance patient safety and improve the overall quality of healthcare. The following steps are essential for obtaining accurate and consistent blood pressure readings, from using the appropriate tools to ensuring effective communication with the patient.

Special considerations while measuring blood pressure

When assessing blood pressure (BP), healthcare professionals must consider various factors and potential unexpected outcomes to ensure accurate readings and provide proper patient care. Adhering to these guidelines is essential to achieving the most reliable results.
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
Measurement of Blood Pressure01:17

Measurement of Blood Pressure

Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a stethoscope.
