Local Anesthetics: Clinical Application as Epidural Anesthesia01:29

Local Anesthetics: Clinical Application as Epidural Anesthesia

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Cardiopulmonary Resuscitation IV: Pharmacological Management

Pharmacologic intervention is crucial in treating cardiac arrest patients during ACLS or Advanced Cardiovascular Life Support. The ACLS algorithms guide the administration of specific drugs based on the patient's cardiac arrest rhythm, which includes pulseless ventricular tachycardia (VT), ventricular fibrillation (VF), asystole, and pulseless electrical activity (PEA).EpinephrineIndication: Epinephrine is the first-line drug for all cardiac arrest rhythms.Mechanism of Action: Epinephrine...

Cardiomyopathy 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...

Cardiopulmonary Resuscitation III: AED Use

Introduction to AEDAn Automated External Defibrillator (AED) is a portable medical device that analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help the heart re-establish an effective rhythm during sudden cardiac arrest (SCA). SCA occurs when the heart suddenly and unexpectedly stops beating, leading to a loss of blood flow to the brain and other vital organs. In such emergencies, time is of the essence, and using an AED, combined with Cardiopulmonary...

Endoscopic Studies II: Thoracocentesis

Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
Local Anesthetics: Clinical Application as Spinal Anesthesia01:11

Local Anesthetics: Clinical Application as Spinal Anesthesia

Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

This summary is machine-generated.

Thoracic epidural analgesia (EDA) does not reduce in-hospital mortality for noncardiac surgery patients. This meta-analysis also found questionable benefits of thoracic EDA in reducing perioperative myocardial infarction rates.

Real-Time Assessment of Spinal Cord Microperfusion in a Porcine Model of Ischemia/Reperfusion

Published on: December 10, 2020

Area of Science:

  • Anesthesiology
  • Cardiology
  • Critical Care Medicine

Background:

  • Thoracic epidural analgesia (EDA) is theorized to offer cardioprotective benefits during noncardiac surgery.
  • Previous meta-analyses yielded conflicting results regarding EDA's impact on perioperative survival.
  • This study aimed to clarify EDA's role in reducing cardiac morbidity and mortality.

Purpose of the Study:

  • To evaluate the potential of thoracic epidural analgesia (EDA) to reduce perioperative cardiac morbidity and mortality.
  • To analyze available randomized controlled trials (RCTs) on thoracic EDA in noncardiac surgery.
  • To provide a quantitative systematic review of the current evidence.

Main Methods:

  • Systematic literature search across major medical databases (Med-Line, Embase, etc.).
  • Inclusion of RCTs published from 1980 to 2008 involving noncardiac surgery patients.
  • Quantitative systematic review using a fixed-effects model with Review Manager 4.1.

Main Results:

  • Nine studies comprising 2,768 patients were analyzed.
  • Thoracic EDA did not significantly reduce perioperative mortality (Peto OR: 1.08, 95% CI 0.74-1.58).
  • A trend towards lower perioperative myocardial infarction was observed but lacked statistical significance (Peto OR: 0.65, 95% CI 0.4-1.05).

Conclusions:

  • Thoracic EDA did not demonstrate a significant positive effect on perioperative in-hospital mortality in noncardiac surgery.
  • The capacity of thoracic EDA to decrease perioperative myocardial infarction rates remains uncertain.
  • Further research may be needed to definitively establish the cardioprotective role of thoracic EDA.
