Deliberate hypotension in head and neck surgery
Head & Neck Surgery
|January 1, 1980
Summary
Deliberate hypotension, a technique to reduce blood loss during surgery, remains controversial due to limited controlled studies. This review examines its effects on organ perfusion and provides recommendations for its application.
Area of Science:
- Anesthesiology
- Surgical Innovation
Background:
- Deliberate hypotension has been used for 30 years to minimize intraoperative blood loss.
- Its clinical application is controversial, with few studies meeting current controlled trial standards.
Purpose of the Study:
- To evaluate the impact of induced hypotension on organ perfusion.
- To review methods for achieving deliberate hypotension.
- To summarize study results and offer clinical recommendations.
Main Methods:
- Review of existing literature on deliberate hypotension.
- Analysis of organ perfusion data in hypotensive states.
- Synthesis of reported outcomes and techniques.
Main Results:
- Data on organ perfusion during induced hypotension is presented.
- Various techniques for achieving hypotension are reviewed.
- A summary of results from reported studies is included.
Conclusions:
- Recommendations for the appropriate use and limitations of deliberate hypotension are provided.
- Further controlled studies are needed to clarify its safety and efficacy.

01:30Alterations 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)...

01:24General 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...

01:22Stages of General Anesthesia
Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...
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...

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
01:14Increased Intracranial Pressure l: Introduction
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
