Disorders of the Autonomic Nervous System

Disorders of the Autonomic Nervous System

The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.
Raynaud's disease, also known as Raynaud's phenomenon, is a...

Hypertension I: Introduction

Hypertension I: Introduction

Hypertension is a widespread, long-term medical condition where blood pressure in the arteries remains elevated. It is characterized by systolic blood pressure readings of 130 mm Hg or above or diastolic blood pressure (DBP) readings of 80 mm Hg or higher. Unmanaged hypertension poses significant health risks, making the distinction between primary (or essential) hypertension and secondary hypertension crucial, as their management and implications vary.Primary HypertensionPrimary hypertension,...

Hypertension II: Pathophysiology

Hypertension II: Pathophysiology

Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

General Anesthesia: Overview

General Anesthesia: Overview

Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

Hypertension and Regulation of Blood Pressure

Hypertension and Regulation of Blood Pressure

Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...

Hypertension III: Clinical Manifestations and Diagnostic Studies

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...

Summary

For patients with systemic hypertension undergoing elective surgery, clear guidelines on acceptable blood pressure levels before anesthesia are lacking. Decisions to cancel surgery should prioritize organ damage over specific blood pressure readings.

Area of Science:

Anesthesiology
Cardiology
Internal Medicine

Context:

Systemic hypertension is common, yet consensus on pre-anesthesia blood pressure thresholds for elective procedures is absent.
Surgical cancellations due to uncontrolled hypertension incur significant costs and logistical challenges.
Ensuring safe anesthesia induction is paramount, necessitating evidence-based practice guidelines.

Purpose:

To review existing literature on hypertension and anesthesia for elective procedures.
To provide evidence-based guidance for clinical practice regarding pre-anesthesia blood pressure management.
To address the lack of consensus on acceptable blood pressure levels before inducing anesthesia.

Summary:

Literature review indicates no established maximum blood pressure levels for elective procedures.

Current criteria for canceling surgery in hypertensive patients often rely on empirical data rather than robust evidence.

A trend exists to cancel procedures if blood pressure exceeds 180/110 mmHg, but individualized assessment is crucial.

Impact:

Highlights the need for evidence-based guidelines to optimize patient safety and resource allocation in anesthesia.
Emphasizes individualized patient assessment, focusing on target-organ injury rather than solely on blood pressure values.
Aims to reduce unnecessary surgical delays and associated healthcare costs by informing clinical decision-making.
