Objective: to evaluate evidence on effectiveness support surfaces for pressure injury prevention in the intraoperative period. Method: systematic review. The search for primary studies was conducted in seven databases. The sample consisted of 10 studies. The synthesis of the results was carried out descriptively and through meta-analysis. Results: when comparing low-tech support surfaces with regular care (standard surgical table mattress), the meta-analysis showed that there is no statistically significant difference between the investigated interventions (Relative Risk = 0.88; 95%CI: 0.30-2.39). The Higgins inconsistency test indicated considerable heterogeneity between studies (I2 = 83%). The assessment of the certainty of the evidence was very low. When comparing high-tech and low-tech support surfaces, the meta-analysis showed that there is a statistically significant difference between the interventions studied, with high-tech being the most effective (Relative Risk = 0.17; 95%CI: 0.05-0.53). Heterogeneity can be classified as not important (I2 = 0%). The assessment of certainty of evidence was moderate. Conclusion: the use of high-tech support surfaces is an effective measure to prevent pressure injuries in the intraoperative period.

MACHADO, Elaine Alves Silva. Occurrence and risk factors of surgical site infection in laparoscopic cholecystectomy. 2017. 83p. Thesis (Master degree)

Objective: identify the occurrence and risk factors related with surgical site infection in patients submitted to videolaparoscopic cholecystectomy. Methods: descriptive study developed at a private hospital, involving 118 patients. For the data collection, a tool was elaborated that was submitted to face and content validation. For the data analysis, the software Statistical Package for the Social Sciences was used. Results: the occurrence of infection amounted to 5.9% (n=7). The cases were diagnosed during post-discharge surveillance. The results showed no statistically significant difference between the research variables and the presence of surgical site infection (bivariate analysis). Conclusion: at the place of study, the occurrence of surgical site infection was high, without an association between the research factors and the presence of this type of infection.
