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...

Inhalational Anesthetics: Overview

Inhalational Anesthetics: Overview

Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...

Parenteral Anesthetics: Overview

Parenteral Anesthetics: Overview

Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.

Stages of General Anesthesia

Stages 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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Area of Science:

Pediatric Anesthesiology
Radiation Oncology
Medical Safety

Context:

Radiotherapy for children under 3 years frequently necessitates anesthesia.
The Paul-Strauss Center documented its experience over a 4-year period.
The study involved 15 pediatric patients undergoing 386 general anesthesia procedures.

Purpose:

To evaluate the safety and complication rates of general anesthesia in pediatric patients undergoing radiotherapy.
To assess the impact of anesthesiologist experience on patient outcomes.

Summary:

A low rate of anesthesia-related complications (0.5%) was observed.
Patient safety was correlated with the expertise of the anesthesiologists.
Adherence to follow-up recommendations was crucial for minimizing risks.

Impact:

This study highlights the safety of anesthesia in pediatric radiotherapy when administered by experienced professionals.
Findings support the implementation of standardized anesthetic protocols and diligent follow-up care for young cancer patients.
The results provide valuable data for optimizing anesthetic management in pediatric radiation oncology settings.
