Tracheostomy Care I: Pre-procedural Steps01:16

Tracheostomy Care I: Pre-procedural Steps

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:
Hand hygiene01:23

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Handwashing II: Pre-procedure and Initial Procedure Steps01:19

Handwashing II: Pre-procedure and Initial Procedure Steps

The pre-procedure steps of handwashing include removing jewelry and rolling up sleeves. However, many organizations allow staff to wear wedding rings.
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury.  The nails must be short and clean, without nail paint...
Tracheostomy Suctioning I: Pre-Procedural Steps01:26

Tracheostomy Suctioning I: Pre-Procedural Steps

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...

Area of Science:

  • Infection control
  • Surgical safety
  • Antimicrobial stewardship

Background:

  • Health-care-associated infections (HAIs) remain a significant clinical challenge, despite advances in medical hygiene.
  • Post-surgical sepsis contributes substantially to patient morbidity and mortality worldwide.
  • Skin antisepsis, introduced in the 19th century, has historically reduced infection rates.

Purpose of the Study:

  • To critically review the existing evidence on the efficacy of preoperative skin preparations.
  • To evaluate the role of preoperative skin antisepsis in preventing health-care-associated infections.
  • To inform clinical practice regarding optimal skin preparation protocols.

Main Methods:

  • Systematic literature search for studies on preoperative skin preparation.
  • Analysis of clinical trials and observational studies.
  • Evidence synthesis on the effectiveness of various antiseptic agents and techniques.

Main Results:

  • Preoperative skin preparation is a cornerstone of surgical site infection prevention.
  • Different antiseptic agents demonstrate varying degrees of efficacy.
  • Adherence to proper application techniques is crucial for optimal outcomes.

Conclusions:

  • Preoperative skin preparation remains a vital intervention in reducing health-care-associated infections.
  • Evidence supports the continued use and optimization of skin preparation protocols.
  • Further research may refine agent selection and application methods for enhanced surgical safety.
