Cardiomyopathy VII: Pre and Post Operative Nursing Management01:28

Cardiomyopathy VII: Pre and Post Operative Nursing Management

248
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Tracheostomy Suctioning I: Pre-Procedural Steps

1.9K
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

911
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:

Suctioning the Oropharyngeal Airway01:25

Suctioning the Oropharyngeal Airway

728
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Area of Science:

  • Anesthesiology
  • Biomedical Engineering
  • Patient Safety

Background:

  • Total electrical power failure in operating rooms is rare but dangerous.
  • Lack of provider knowledge about equipment function during power outages is a critical safety gap.

Purpose of the Study:

  • To assess the battery capabilities and function duration of anesthesia equipment during power failures.
  • To develop a site-specific power failure protocol for operating rooms.

Main Methods:

  • Evaluated internal battery function and duration for anesthesia gas machines (AGM), vital sign monitors, and infusion pumps.
  • Simulated total power failure to test equipment performance.

Main Results:

  • Anesthesia gas machine battery life differed significantly from manufacturer claims.
  • Integrated vital sign monitors failed immediately; portable monitors and infusion pumps lasted 150 and 270 minutes, respectively.

Conclusions:

  • Many critical operating room devices have limited or no function during power failures.
  • Site-specific protocols are essential for managing patient care during total electrical power outages.
