Perforations of tri-layer nitrile-latex and natural rubber latex gloves during ex-vivo equine intestinal anastomoses.
Abstract: To compare perforation rates between tri-layer nitrile-latex and natural rubber latex surgical gloves after single-layer end-to-end jejunojejunal anastomoses in equine cadavers. Methods: Prospective randomized ex-vivo study. Methods: Pairs of surgical gloves (n = 46) worn during jejunojejunal anastomoses. Methods: Tri-layer nitrile-latex and rubber latex pairs of gloves were equally but randomly allocated to a right-handed surgeon performing 46 single-layer end-to-end jejunojejunal anastomoses on cadaveric material. Number and location of perforations were determined with the water leak test after each procedure. Ten unused pairs of both glove types were tested as controls. Results: At least one perforation occurred in 41% (19/46) of the pairs of gloves. Glove perforations were present in 22% (5/23; 95% CI: 9-42) of tri-layer glove pairs and 61% (14/23; 95% CI: 41-78) of the rubber glove pairs. The odds of glove perforation were 5.6 times (p = .009, 95% CI: 1.5-20.5) lower when tri-layer rather than rubber gloves were used. The duration of procedure did not affect the risk of glove perforation (p = .679). No perforations were observed in the unused gloves. Conclusions: Perforations were less common when the surgeon wore tri-layer nitrile-latex gloves rather than to the natural rubber latex gloves tested in this study. Conclusions: Tri-layer nitrile-latex gloves were more resistant to perforations in experimental settings; further studies may confirm that they are also superior in a clinical setting.

The research tests the resilience of tri-layer nitrile-latex and natural rubber latex gloves to perforations during equine intestinal surgeries. The study found that tri-layer nitrile-latex gloves had fewer cases of perforations compared to the natural rubber latex gloves.
Research Methodology
- This research used a prospective randomized ex-vivo study design to compare the perforation rates between the two types of gloves.
- The gloves were worn during single-layer end-to-end jejunojejunal anastomoses, a surgical procedure performed on equine cadavers.
- A total of 46 pairs of gloves were used, distributed equally between the two types and randomly assigned to a right-handed surgeon.
- The study determined the number and location of perforations using a water leak test after each procedur
- As a control measure, ten unused pairs from both glove types were also tested.
Research Findings
- Perforations occurred in 41% (or 19 out of 46) of the pairs of gloves used during the procedures.
- The tri-layer gloves had a significantly lower perforation rate at 22% (or 5 out of 23 pairs) compared to 61% (or 14 out of 23 pairs) for the rubber latex gloves.
- The odds of glove perforation were found to be 5.6 times lower if tri-layer gloves were used instead of rubber latex gloves, a finding which was statistically significant (p = .009).
- The duration of the surgical procedure was found to have no effect on the risk of glove perforation (p = .679).
- No perforations were observed in any of the unused control pairs.
Conclusion
- The research concluded that tri-layer nitrile-latex gloves were less prone to perforations compared to natural rubber latex gloves in the given study setting.
- Tri-layer nitrile-latex gloves demonstrated superior resistance to perforations in this experimental setting, indicating potential benefits in actual clinical settings as well, although further studies are needed for confirmation.
