Radiological Investigation II: MRI and Ventilation Perfusion Scan01:30

Radiological Investigation II: MRI and Ventilation Perfusion Scan

568
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

General Anesthesia: Overview

627
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...

Stages of General Anesthesia

1.6K
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...

Leaky Scanning

5.7K
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA.  Marilyn Kozak discovered that the sequence RCCAUGG (where R...

Data Reporting and Recording

5.4K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

Area of Science:

  • Anesthesiology
  • Medical Imaging
  • Oral and Maxillofacial Surgery

Background:

  • Magnetic Resonance Imaging (MRI) environments pose unique challenges for standard anesthesia equipment due to intense magnetic fields.
  • Oral and maxillofacial surgery often requires high-quality imaging, necessitating patient immobilization during MRI scans.

Observation:

  • Two pediatric cases (15-year-old with developmental disability, 5-year-old healthy) undergoing oral maxillofacial surgery MRI were managed with general anesthesia.
  • Anesthesia was initiated in the MRI room, involving endotracheal intubation and total intravenous anesthesia with propofol.
  • Physiologic monitoring adapted to the MRI environment, using standard monitors during pauses and specialized equipment during scanning.

Findings:

  • Total intravenous anesthesia with propofol infusion (4-7 mg/kg/h) provided adequate anesthesia and airway control.
  • General anesthesia facilitated complete patient immobilization, crucial for obtaining diagnostic-quality MRI images.

Implications:

  • General anesthesia is recommended over sedation for pediatric oral and maxillofacial surgery patients undergoing MRI, particularly those with disabilities or of pre-cooperative age.
  • This approach ensures airway security and patient cooperation, leading to improved diagnostic accuracy in complex surgical cases.
