Conclusions This systemic review shows that preoperative interventions can be beneficial in improving wound healing and scar formation .
In selected cases , wound healing was found to benefit from a higher preoperative body temperature , topical vitamin E application , and low patient stress levels .
Background Poor wound healing and scar formation  remain critical problems in daily surgical practice .
Generally , most attention is paid to intra- and postoperative interventions to improve wound healing after surgery , while preoperative interventions remain unsatisfactorily explored .
Objectives In this systematic review , the available literature on the beneficial effects of preoperative interventions on wound healing and scar formation have been summarized and compared .
Enhanced wound healing after emotional disclosure intervention.
OBJECTIVES Psychological stress is believed to impair wound healing via a down-regulation of the immune system . Since previous research suggests that disclosure of tra-umatic experiences can result in an up-regulation of immune function , the present study aim ed to investigate the impact of a disclosure intervention on the progress of wound healing . DESIGN The study used a prospect i ve , longitudinal design with r and om assignment to the control ( writing about time management ) and experimental group ( writing about a traumatic event ) . METHODS Participants ( N=36 ) completed question naires measuring perceived and emotional distress , loneliness , self-esteem , social support , dispositional optimism , and health-related behaviours . Accurate indication of the healing of a small punch biopsy wound was determined by using a high-resolution ultrasound scanner . RESULTS Repeated measures ANOVA indicated that the disclosure intervention impacted wound healing . Participants who wrote about traumatic events had significantly smaller wounds 14 and 21 days after the biopsy compared with those who wrote about time management . CONCLUSIONS It is concluded that a relatively brief and easy to administer intervention can have beneficial effects on wound healing . The potential for use in patient sample s is indicated
