Tracheostomy Suctioning II: Procedure01:23

Tracheostomy Suctioning II: Procedure

1.2K
Tracheostomy suctioning is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...

Tracheostomy Suctioning I: Pre-Procedural Steps

1.7K
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...

Suctioning the Oropharyngeal Airway

654
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...

Handwashing II: Pre-procedure and Initial Procedure Steps

1.4K
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...

Endoscopic Studies II: Thoracocentesis01:26

Endoscopic Studies II: Thoracocentesis

1.1K
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Summary
This summary is machine-generated.

Saline lavage in revision arthroplasty can aid prosthetic joint infection (PJI) diagnosis when initial aspiration yields no fluid. The percentage of polymorphonuclear cells (%PMN) in lavage fluid remains a reliable indicator of PJI.

Area of Science:

  • Orthopedic Surgery
  • Infectious Disease
  • Diagnostic Microbiology

Background:

  • Prosthetic joint infection (PJI) diagnosis can be challenging, especially with
  • dry
  • aspirations.
  • Saline lavage is a common technique to obtain synovial fluid samples in such cases.
  • The impact of saline lavage on diagnostic accuracy in revision arthroplasty requires further investigation.

Purpose of the Study:

  • To prospectively evaluate the effect of saline lavage on synovial fluid analysis for diagnosing PJI in revision arthroplasty.
  • To compare pre- and post-lavage synovial fluid white blood cell (WBC) count and percent polymorphonuclear cells (%PMN).

Main Methods:

  • Prospective study of patients undergoing revision hip or knee arthroplasty.
  • Simulated
  • dry tap
  • by aspirating fluid before arthrotomy, followed by 20 ml saline lavage and re-aspiration.
  • Comparison of pre- and post-lavage WBC count, %PMN, and culture results.

Main Results:

  • Saline lavage significantly reduced synovial fluid WBC count in both septic and aseptic cases.
  • The %PMN remained similar between pre- and post-lavage samples, particularly in septic patients.
  • Post-lavage aspirates showed a sensitivity of 75% and specificity of 95% for PJI detection at an 80% PMN cutoff.
  • Fluid cultures had reduced positivity after saline lavage.

Conclusions:

  • Saline lavage in revision arthroplasty does not significantly alter the %PMN, maintaining its diagnostic utility for PJI detection.
  • Despite a decrease in WBC count, the %PMN in post-lavage fluid provides a reliable indicator for PJI diagnosis in cases of dry taps.
  • The %PMN of saline lavage aspirates offers reasonable sensitivity for PJI detection in challenging diagnostic scenarios.
