Summary
Suction systems in orthopedic surgery can become contaminated, potentially leading to deep wound infections. Bacterial contamination of suction tips was common (54%), especially in longer procedures, though deep infections remained rare.
Area of Science:
- Orthopaedic Surgery
- Infection Control
- Microbiology
Background:
- Suction systems are essential in orthopedic procedures.
- Contamination of suction systems poses a risk of deep wound infection.
- Proactive measures are needed to mitigate infection risks.
Purpose of the Study:
- To assess the bacterial contamination rate of suction catheter tips in orthopedic procedures.
- To identify factors associated with suction tip contamination.
- To evaluate the incidence of deep wound infection in relation to suction system use.
Main Methods:
- Prospective study of 50 patients undergoing elective and trauma orthopedic procedures.
- Suction catheter tips were cultured post-procedure.
- Correlation of contamination with procedure duration and outcomes.
Main Results:
- Bacterial contamination of suction tips occurred in 54% of cases.
- Staphylococcus species were the most common contaminants (77.8%).
- Contamination rates were significantly higher in procedures exceeding one hour (66.7%) compared to shorter ones (9.1%).
Conclusions:
- Despite high contamination rates, deep wound infection was infrequent (1 case).
- Prolonged operative times increase suction tip contamination risk.
- Regular suction tip changes or use of the on/off switch during lengthy procedures is recommended to minimize infection risk.

01:25Suctioning the Oropharyngeal Airway
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...

01:29Suctioning the Nasopharyngeal Airway
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

01:26Tracheostomy 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.

01:23Tracheostomy Suctioning II: Procedure
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...

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

01:26Endoscopic Studies II: Thoracocentesis
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...
