Study type
Description of intervention(s) / exposure
A topical cream containing benzyl nicotinate will be applied on the site of planned surgical incision. This molecule has a distinct vasodilative effect peaking at the 10th minute of application which lasts about 45 minutes. The cream which contains benzyl nicotinate also contains etofenamate; an antiinflammatory agent. The cream is placed in a syringe with the needle removed. The cream is applied to the incision with a dose of 1 mg benzyl nicotinate applied to each cm of the wound (1 ml cream/10 cm). The cream is applied on the operating table on the planned incision. The necessary amount will be distibuted homogenously on the planned incision with a width of 1 cm. Then the skin is prepared and draped. The surgery goes on as usual. The observation period is 30 postoperative days.
Intervention code [1] 3744 0
Comparator / control treatment
A gel containing only etofenamate as the active agent will be used as the control. In order to apply the same dose of etofenamate as applied in the study group (10 mg to each cm) 2 ml of the control gel will be applied to each 10 cm of the planned wound. The operation goes on as usual as described in the intervention group.
Control group

Primary outcome [1] 5115 0
Surgical site infection. This will be assessed by monitorization of the health care professionals. If the wound is opened microbiological culture assessment will be done additionally.
Timepoint [1] 5115 0
Within 30 days of the operation.
Secondary outcome [1] 8612 0
All cause mortality. This will be assessed by health care professionals if the patient is still hospitalized. If the patient is discharged within the time frame of the study the patient will be invited for clinical examination. If this is not possible the patient will be contacted by telephone.
Timepoint [1] 8612 0
Within 30 days of the operation.

Brief summary
Wound infection following general surgical operations is a serious problem. As the number of the surgical procedures performed is large, any intervention having the potential to decrease this morbidity even by a small fraction will be beneficial. The most important barrier to infection is a healthy, well vascularized wound. A cream containing benzyl-nicotinate dilates the capillaries and small vessels and increases the blood flow in the skin and subcutaneous tissues when applied to the skin. In this study, the effect of this vessel dilating cream will be assessed on wound infection in patients undergoing general surgical operations.
