Glove punctures and postoperative skin flora of hands in cardiac surgery

Area of Science:

• Surgical safety
• Infection control
• Medical device integrity

Background:

• Surgical glove perforation is a common occurrence during operations, particularly cardiac procedures.
• The associated infection risk is not adequately understood or addressed.
• Understanding glove integrity is crucial for preventing surgical site infections.

Purpose of the Study:

• To investigate the relationship between surgical operation duration and glove perforation rates.
• To assess bacterial contamination on surgeons' hands in relation to glove integrity and operation length.
• To provide evidence-based recommendations for reducing infection transmission during surgery.

Main Methods:

• Bacterial samples were collected from 800 surgeons' hands after 116 cardiac operations.
• Glove punctures were identified using a water test post-operation.
• Correlation between operation duration, glove breakage, and bacterial counts was analyzed.

Main Results:

• 39% of gloves exhibited holes in postoperative testing.
• Glove breakage rates escalated with operation duration, from 30% (under 3 hours) to 65% (over 5 hours).
• Higher bacterial counts on hands were observed after longer surgical procedures.

Conclusions:

• Surgical glove integrity is compromised more frequently in longer operations.
• Increased operation time correlates with higher glove puncture rates and bacterial hand contamination.
• Recommendations include changing both gloves upon detecting a puncture and re-disinfecting hands before donning new gloves.
