Abstract

Insights

The incidence of postoperative venous thromboembolism (VTE) following interventional MRI (iMRI) procedures is low, even without pneumatic compression devices (PCD). This study found a 0.95% VTE rate in iMRI surgeries.

Area of Science:

  • Medical Imaging
  • Neurosurgery
  • Vascular Surgery

Background:

  • Interventional MRI (iMRI) enables real-time guidance for electrode and microcatheter placement.
  • MRI-compatible pneumatic compression devices (PCD) for venous thromboembolism (VTE) risk reduction are not commercially available.
  • Limited data exists on VTE incidence and patient characteristics following iMRI procedures.

Purpose of the Study:

  • To investigate the incidence of postoperative VTE in patients undergoing iMRI procedures.
  • To assess VTE risk in iMRI surgeries performed without the use of PCD.

Main Methods:

  • Retrospective review of medical records and operative times for iMRI procedures.
  • Statistical analysis of patient demographics and surgical durations using ANOVA and t-tests.
  • In-depth chart review for patients who experienced postoperative VTE.

Main Results:

  • A low incidence of postoperative VTE was observed (0.95%, 2 out of 210 procedures).
  • Significant differences in procedure times were noted between unilateral electrode, bilateral electrode, and bilateral gene therapy procedures.
  • Both VTE cases occurred in procedures with longer-than-average operative times.

Conclusions:

  • Postoperative VTE incidence following iMRI procedures is low, even without intraoperative PCD use.
  • The findings suggest that current iMRI practices may not necessitate routine PCD use for VTE prevention.

Nursing Interventions I: Taxonomy of Nursing Interventions

Nursing interventions are chosen as part of the planning process to achieve patient outcomes. Once nursing diagnoses are determined, the goals and outcomes are specified, then the nursing interventions are selected and individualized according to the patient's situation.
A nursing intervention is a treatment or action based on scientific concepts and knowledge from the nursing, behavioral, and physical sciences. Identifying and prioritizing nursing interventions based on the desired outcome...

Nursing Interventions II: Selecting and Classifying the Nursing Interventions

Creating and executing a nursing diagnosis helps nurses plan care and guide patient, family, and community interventions. They are developed based on a patient's physical evaluation and support measuring the outcomes. It is not recommended to select random interventions throughout the planning process. Instead, consider the following six essential factors when choosing interventions:

Venous Return

The circulatory system plays a crucial role in ensuring the optimal functioning of the human body. One of its critical components is venous return - the process that completes the blood circulation cycle. This article will delve into the concept of venous return, how it works, and its significance to our health.
What is Venous Return?
Venous return refers to the rate at which blood flows back to the heart from the body's peripheral veins. It's an integral part of the circulatory system...

Venous Thrombosis I: Introduction

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Operant Conditioning Intervention01:24

Operant Conditioning Intervention

Operant conditioning serves as a foundational principle in therapeutic interventions aimed at modifying maladaptive behaviors. Central to this approach is the notion that behaviors, both adaptive and maladaptive, are learned through reinforcement. By analyzing the environmental factors that reinforce problematic behaviors, clinicians can design interventions to weaken these reinforcements and replace maladaptive behaviors with healthier alternatives.
In operant conditioning, behaviors that are...
