Summary
In clean orthopaedic surgery, 7.3% of suction cannulas showed bacterial colonization, increasing significantly with longer use. Extended use of these surgical tools elevates infection risk.
Area of Science:
- Orthopaedic Surgery
- Infectious Diseases
- Medical Device Safety
Background:
- Osteoarticular infections are a significant complication in orthopaedic surgery.
- Suction cannulas are critical tools used during these procedures.
- Understanding cannula contamination is vital for patient safety.
Purpose of the Study:
- To determine the colonization rate of suction cannulas in clean orthopaedic surgery.
- To investigate the relationship between cannula usage duration and colonization.
- To assess the risk of pathogen presence on surgical instruments.
Main Methods:
- A prospective study analyzed 546 suction cannulas from clean orthopaedic surgeries.
- Cultures were performed on the distal end of each cannula.
- Data was collected from November 2017 to March 2018 in a trauma center.
Main Results:
- A colonization rate of 7.3% was observed among the analyzed cannulas.
- Staphylococcus epidermidis was the most frequently identified pathogen (27.5%).
- Cannula use exceeding 60 minutes significantly increased colonization risk, with over 90 minutes showing an 8-fold higher risk.
Conclusions:
- The observed cannula colonization rate is lower than previously reported in literature.
- Prolonged use of suction cannulas in surgery directly correlates with an increased risk of colonization.
- Further research is needed to link cannula colonization to postoperative infection rates.

01:25Suctioning the Oropharyngeal Airway
639
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...

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.

01:30Bacterial Signaling
39.6K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

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.
