Aneurysm IV: Nursing Management

507
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

511
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:

  • Medical Imaging
  • Radiology
  • Interventional Neurology

Background:

  • Neuroendovascular procedures carry risks associated with radiation exposure.
  • Optimizing radiation doses is crucial for patient safety and minimizing cumulative exposure.

Purpose of the Study:

  • To evaluate the effectiveness of implemented strategies in reducing radiation doses during neuroendovascular procedures.
  • To quantify the impact of customized imaging protocols and behavioral changes on radiation exposure.

Main Methods:

  • Utilized a Rando-Alderson phantom for controlled dose measurements.
  • Developed and implemented customized imaging protocols for pediatric and adult neuroendovascular procedures.
  • Retrospectively analyzed estimated skin doses (ESD) and dose-area product (DAP) over 4.5 years.

Main Results:

  • Customized protocols combined with behavioral modifications led to a >50% reduction in radiation dose estimates.
  • Significant dose reduction was observed compared to standard vendor-recommended protocols.
  • The findings were consistent across both pediatric and adult patient cohorts.

Conclusions:

  • A combined approach of equipment modification and operator behavior significantly reduces radiation exposure in neuroendovascular procedures.
  • These findings support the adoption of tailored imaging protocols to enhance safety in interventional neuroradiology.
  • Substantial radiation dose reduction is achievable, benefiting patient outcomes and radiation safety.
