In another study, with the use of double latex gloves, the number of punctures correlated directly with the
duration of the operation, and all gloves had punctures after procedures that lasted more than 180 minutes [35].
Other research has shown that gloves used exclusively for draping are most likely to be contaminated [36].
Based on these studies,routine changing of the outer gloves after draping,
as well as during procedures that last more than several hours, is advisable to protect both the surgeon and the patient.
