Cardiac Catheterization I: Pre-Procedure Overview01:28

Cardiac Catheterization I: Pre-Procedure Overview

320
Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Tracheostomy Suctioning I: Pre-Procedural Steps

1.4K
Tracheostomy suctioning is a critical procedure healthcare professionals perform to maintain a patent airway in patients with a tracheostomy tube. This procedure is necessary when secretions accumulate in the airway, causing respiratory distress. Here is a step-wise procedural guide for performing tracheostomy suctioning using an open system.
Equipment Required
First, gather all necessary equipment: a sterile suction catheter, a sterile disposable container, sterile gloves, a towel or...

Tracheostomy Care I: Pre-procedural Steps

482
A tracheostomy is a surgical technique that involves making an incision in the neck to provide access to the trachea. It is frequently used in medical conditions such as airway obstruction and prolonged mechanical ventilation. Effective nursing management is crucial for the long-term success of a tracheostomy.
Required Equipment
The equipment necessary for tracheostomy care includes:

Endotracheal Tube Extubation01:24

Endotracheal Tube Extubation

2.0K
Endotracheal tube extubation is a critical procedure in weaning patients from mechanical ventilation. It involves physically removing the oral or nasal endotracheal (ET) tube, marking the final step in liberating a patient from ventilatory support.
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals....

Cardiac Catheterization IV: Nursing Management

319
Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...

Tracheostomy Care II: Procedure

572
Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
Step 1: Perform hand hygiene, and put on personal protective equipment: gown, gloves, mask...

Area of Science:

  • Neurology
  • Interventional Neuroradiology
  • Biomedical Engineering

Background:

  • Mechanical thrombectomy is a critical treatment for large and medium vessel occlusions.
  • The Trevo NXT stent retriever features a new coating aimed at improving device handling.
  • Initial clinical experience with this enhanced device is evaluated.

Purpose of the Study:

  • To assess the initial safety and efficacy of the Trevo NXT stent retriever.
  • To evaluate reperfusion rates and clinical outcomes in patients undergoing mechanical thrombectomy.
  • To gather interventionalist feedback on device functionality.

Main Methods:

  • A retrospective pooled analysis of data from four European stroke centers (October 2020 - February 2021).
  • Inclusion criteria: use of Trevo NXT as a first-line device for large/medium vessel occlusions.
  • Primary endpoint: first-pass near-complete/complete reperfusion (mTICI ≥2c); secondary endpoints: final reperfusion, NIHSS scores, complications, device performance.

Main Results:

  • Eighty patients (mean age 74 years) were included; 93% underwent a primary combined approach.
  • First-pass reperfusion (mTICI ≥2c) achieved in 54% (near-complete) and 43% (complete).
  • Final reperfusion rate was 96%, with no device malfunctions and a low rate of symptomatic intracranial hemorrhage (4%).

Conclusions:

  • The Trevo NXT stent retriever is an effective and safe device for mechanical thrombectomy.
  • The device shows particular promise when utilized in combined approaches for large vessel occlusion treatment.
  • Initial data supports its utility in improving patient outcomes for acute ischemic stroke.
