Background: Splash basins are used in orthopaedic surgery cases to wash and hold instrumentsintraoperatively. This systematic review aims to summarize information on contamination of splash basins intraoperatively.
Methods: A systematic review was conducted using the following search terms: "splash basin" or "splash bucket." Two authors independently reviewed the literature. Studies were included if they reported on intraoperative splash basin contamination rates. Studies were excluded if they were not relevant to orthopaedic surgery, non-English articles, or repeat studies yielded by different online databases.
Results: There were seven studies included in this review. The median contamination rate of sterile water or physiologic saline splash basins was 23.9% [range: 2%-74%]. The addition of surgical antiseptics to sterile water splash basins was associated with 0% contamination rates in two studies. The most frequent splash basin contaminants identified in bacterial culture were coagulase negative staphylococcus (50%) and staphylococcus aureus (10%).
Conclusion: The splash basin appears to be a frequent source of contamination in the operating room. Many studies suggest abandoning splash basin use altogether, although the efficacy of alternative methods such as cleaning instruments with lap pads in avoiding contamination of the sterile field has not been studied. Further investigation into surgical teams' use of the splash basin and the contents of the splash basin as they relate to contamination rates may help advance our understanding of optimal use of this surgical tool. Shorter case durations and dilute surgical antiseptics in splash basins appear associated with lower splash basin contamination risk. .

: Preventing postoperative infection and promoting patient safety are essential responsibilities of the operating room nurse. In some hospitals, splash basins are used to rinse instruments during surgery, although previous studies emphasise the risk of bacterial contamination. A recent systematic review calls for further investigation into surgical teams' use of splash basins.

The impact of a liquid drop on a granular medium is a common phenomenon in nature and engineering. The possible splashing droplets and ejected particles could pose a risk of pathogen transmission if the water source or granular medium is contaminated. This work studies the liquid drop impact on the granular medium using high-speed photography and considers the effects of liquid properties, drop impact characteristics, and granular medium properties.

Comparative methods are central for understanding the distribution of biodiversity. Assessing spatial variation of multiple species can identify biodiversity drivers across landscapes, including on the genetic level. Molecular ecology approaches have expanded in spatial precision, from phylogeography to landscape genetics, as have molecular tools that now allow genome-scale inferences for virtually any organism.

Background: In healthcare environments, sinks are being increasingly recognized as reservoirs for multidrug-resistant Gram-negative bacteria. In our hospital, carbapenemase-producing, Verona Integron-encoded Metallo-beta-lactamase (VIM)-positive Pseudomonas aeruginosa (VIM-PA) was detected at low endemicity in patients, and environmental culturing revealed that sink drains were primary reservoirs. Therefore, an intervention was initiated in several wards to install sink drain plugs as physical barriers against splashing to prevent transmission of VIM-PA from drain reservoirs to the surrounding sink environment.
