Show moreCorticosteroids are often administered prophylactically to attenuate the inflammatory response associated with cardiac surgery using cardiopulmonary bypass (CPB). However, the efficacy and safety profile of corticosteroids remain uncertain. The primary aim of this systematic review and meta-analysis was to investigate the effect of corticosteroids on mortality in adult cardiac surgery using CPB. Secondary aims were to examine the effect of corticosteroids on myocardial adverse events, pulmonary adverse events, atrial fibrillation, surgical site infection, gastrointestinal bleeding and duration of stay in the intensive care unit and hospital. Randomized controlled trials (RCTs) were systematically searched in electronic databases (MEDLINE, EMBASE, CINAHL, CENTRAL and Web of Science) from their inception until March 2019. Observational studies, case reports, case series and literature reviews were excluded. Sixty-two studies (n = 16 457 patients) were included in this meta-analysis. There was no significant difference in mortality between the corticosteroid and placebo groups [odds ratio (OR) 0.96, 95% confidence interval (CI) 0.81-1.14; P = 0.65, participants = 14 693, studies = 24, evidence of certainty: moderate]. Compared to those receiving a placebo, patients who were given corticosteroids had a significantly higher incidence of myocardial adverse events (OR 1.17, 95% CI 1.03-1.33; P = 0.01, participants = 14 512, studies = 23) and a lower incidence of pulmonary adverse events (OR 0.86, 95% CI 0.75-0.98; P = 0.02, participants = 13 426, studies = 17). The incidences of atrial fibrillation (OR 0.87, 95% CI 0.81-0.94; P < 0.001, participants = 14 148, studies = 24) and surgical site infection (OR 0.81, 95% CI 0.73-0.90; P < 0.001, participants = 13 946; studies = 22) were all lower in patients who were given corticosteroids. In the present meta-analysis of 62 RCTs (16 457 patients), including the 2 major RCTs (SIRS and DECS trials: 12 001 patients), we found that prophylactic corticosteroids in cardiac surgery did not reduce mortality. The clinical significance of an increase in myocardial adverse events remains unclear as the definition of a relevant myocardial end point following cardiac surgery varied greatly between RCTs.

Show moreBackground: Surgical resection is the standard of care for parotid gland tumors. Comprehensive reports on the surgical complications of parotidectomy are lacking. This study focuses on surgical wound complications of parotid gland surgery.Patients and methods: In the period 2002-2012, 390 consecutive patients (395 procedures) who underwent parotid gland surgery were selected for retrospective analysis. Based on subsequent management, the impact of surgical site complications was graded by the Clavien-Dindo Classification (CDC).Results: In 83 (21.0%) of the procedures, at least one complication was registered. In total, 118 complications were described. Rated to CDC, 61 patients (15.4%) were graded as class 2 or higher. This implies therapy was dictated. Fortyfive (11.4%) of the complications were surgical site infections (551). In 9 patients (2.3%) surgical complications required a surgical intervention under general anesthesia (CDC class 3b), and in 19 patients (4.8%) other invasive treatment (CDC class 3a) was needed.Conclusions: The Clavien-Dindo Classification proved to be very useful for retrospective registration of surgical complications. Of the 61 patients, 33 were managed by conservative therapy. No risk profile was found for patients at risk for direct surgical complications.

Show moreSurgical site infections (SSI) are the most-common healthcare-associated infections among surgical patients and have severe adverse consequences. Surveillance is the ongoing systematic collection, analysis, interpretation, and feedback of data, and has been accepted worldwide as a primary step toward prevention of healthcare-associated infections. In the Netherlands, a national network for the surveillance of healthcare-associated infections was set up in 1996 and called PREZIES (__PREventie van ZIEkenhuisinfecties door Surveillance__). In this thesis, the quality of the SSI surveillance within this network is evaluated. The method for postdischarge surveillance recommended by PREZIES seemed feasible and effective, and the mandatory validation visits ensured reliability and robustness of the surveillance data. Furthermore, the predictive power of the NNIS risk index was sufficient for several surgical procedures and could not be significantly improved by using other procedure-specific determinants. Analysis of the time-trend in SSI rates for five surgical procedures showed encouraging decreasing trends, although mostly not statistically significant. Comparison of the Dutch and German SSI surveillance data revealed that even though similar infection surveillance protocols were used, differences occurred in the implementation which hampered the comparison of SSI rates. Additionally, PREZIES contributed to a multi-center intervention project to improve the quality of surgical prophylaxis. Show less
