Influence of dressing application time after breast augmentation on cutaneous colonization: A randomized clinical trial.

Concepts regarding the best way to treat a surgical wound vary, in literature, ranging from no dressing use to dressing maintenance for 24 to 48 hours or until suture removal. This study aimed to evaluate the influence of the length of dressing maintenance after breast augmentation with implants on cutaneous colonization and surgical site infection. This is a two-arm, parallel group, randomized clinical trial. Eighty patients who were candidates for augmentation mammoplasty with silicone implants were randomly allocated to two groups, in which the dressing was removed on postoperative day 1 (group A, n = 40) or postoperative day 6 (group B, n = 40). Cutaneous colonization was examined by culturing samples collected before and after dressing removal. The criteria defined by the Centers for Disease Control and Prevention were used to assess surgical site infection. No significant difference regarding cutaneous colonization was observed between groups before dressing application. On postoperative day 6, significantly more bacterial growth was observed in group A (p = 0.01). No surgical site infection occurred. We concluded that maintaining the dressing for 6 days led to a lower cutaneous colonization but did not influence surgical site infection rates.

Evolution of reports of randomised clinical trials in plastic surgery.

Well-designed, well-conducted and well-reported randomised clinical trials (RCTs) can significantly impact medical care, by contributing to a strong evidence base from which clinical guidelines can be derived. In a previous study, we assessed the quality of reports of RCTs in plastic surgery published from 1966 to 2003. The aim of the present study was to verify what have changed over the last years. RCTs in plastic surgery published from 2004 to 2008 were identified through electronic searches, and classified according to their allocation concealment. Trials with allocation concealment appropriately described were evaluated as to their quality. Two independent reviewers performed the evaluations, using two tools: the Delphi List and the Jadad's quality scale. From 3840 identified studies, 96 were selected for classification according to allocation concealment; 28 (29%) of them appropriately described allocation concealment. From 1966 to 2003, 34 (17%) RCTs appropriately described allocation concealment (χ2=22.98, p<0.000). In the evaluation of the 28 RCTs by the Delphi List, the agreement coefficient between raters (kw) was 0.46 (z=7.24, p<0.000). Groups were similar at baseline in 96.4% of these trials, and this was the only item of the Delphi List, which significantly improved when compared with the period from 1966 to 2003 (χ2=18.53, p<0.000). When evaluated by Jadad's criteria, 14% of the RCTs were scored two points or less and thus considered of low quality (kw=0.72, z=8.57, p<0.001). From 1966 to 2003, 59% of RCTs were scored two points or less (χ2=17.07, p<0.004). We concluded that the quality of reports of RCTs in plastic surgery (as measured by the Jadad's criteria and only one component of the nine components of the Delphi List) significantly increased over the last years.

Quality of life outcomes after pedicled TRAM flap delayed breast reconstruction.

OBJECTIVES: To evaluate the impact of TRAM flap delayed breast reconstruction on health related quality of life in patients who had undergone mastectomy. METHODS: Twenty-five patients following mastectomy were selected consecutively from the Plastic Surgery/Mastology Units of two university hospitals. All subjects underwent breast reconstruction with the use of pedicled TRAM flap. The patients' health related quality of life was assessed by a validated instrument, the SF-36 Health Survey Questionnaire. This was applied preoperatively and postoperatively at 3, 6 and 12-months follow-up. A group of 20 women with mastectomies who have not undergone breast reconstruction was used as a control. To assess patients' satisfaction with breast reconstruction we used Alderman's modified general satisfaction subscale. RESULTS: There was a progressive improvement in all dimensions of the SF-36, and this was statistically significant for seven of the eight dimensions. The scores were significantly higher on 'role emotional' and 'mental health' at 3 months postoperatively, on 'health perception' and 'role physical' at month 6 and on 'physical function', 'pain', health perception and 'social function' at postoperative month 12. Despite the increase in scores, no significant changes in 'vitality' were found. There was no significant preoperative difference between the control group and studied patients, and the control group's scores were significantly lower in all dimensions when compared to postoperative month 12, except on 'physical function'. The level of patients' satisfaction with the TRAM flap breast reconstruction was high. CONCLUSIONS: The data of this study suggest that delayed breast reconstruction with the use of the pedicled TRAM flap provides an improvement in health related quality of life of patients who have undergone mastectomy.
