Study Overview
Brief Summary
Context: The hyperglycemia is an important independent risk factor for the Surgical Site Infection (SSI) development among liver transplantation recipients. Objective: To evaluate the effects of an intensive postoperative protocol of blood glucose management on the surgical site infection incidence among liver transplantation recipients. Material and methods: It is an open-label clinical trial that will be randomized into 2 groups of blood glucose (BG) control: patients will undergo BG control regular in the facility chosen to research development (BG targeted 130-180 mg/dL) and the second one will undergo intensive BG control (BG targeted 80 - 130 mg/dL) until patients are eating at least 50% of a full liquid diet or receiving bolus tube feedings. A computer program will be employed to generate the randomized schedule that will be put into sequentially numbered opaque sealed envelopes by an external expert to research. A finger prick device will be used to measure the blood glucose. A blinded adjudication committee to analyse the primary endpoint SSI will adopt the SSI criteria given by the Centers for Disease Control and Prevention. The research proposal will be registered on ClinicalTrials.gov database. Central tendency and dispersion measures, Pearson's χ2 test, Fisher's Exact Test, Mann-Whitney, Wilcoxon-Mann-Whitney and survival analysis by Kaplan-Meier estimated and Log-rank test will be used for data analyses. Expected outcomes: The results of the study should contribute to establishing better clinical practices on glycemic control in the liver transplantation recipient's postoperative period aiming to reduce SSI incidence and its associated morbidity and mortality.
Detailed Description
The Surgical Site Infections (SSI's) are the most frequent healthcare-associated infections and are an important infectious complication in the postoperative period among liver transplantation (LT) recipients. SSI incidence among LT recipients, whose allografts were from deceased donors, varied from 9.6% to 35.5% according to a recent literature review. In general surgical procedures, SSI increases the length of stay, morbidity and healthcare costs. Besides that, among LT recipients SSI can raise the risks of the allografts dysfunctions, acute rejections and as a consequence a reduction in the recipient's survival.
There are several risk factors for SSI among LT recipients. There is a relationship among supply sterilization quality, the characteristics of surgical procedure, the operation room environment as well as the allograft's and recipient's conditions and SSI occurrence. In regard to LT recipients, results from previous research highlighted hyperglycemia as an important independent predictor of SSI. Furthermore, regarding this population, it is known from observational studies that LT recipients affected by hyperglycemia are exposed, approximately, to three times the risk of SSI comparatively to LT recipients not exposed.
The concern about maintaining normoglycaemia in acute care facilities is not recent; several studies have been done including on clinical and surgical patients from some medical specialities showing the morbidity and mortality reduction throughout the adoption of strict glycaemic control protocols.
However, among critical surgical patients the LT recipients are highlighted; since they are exposed to impairment in blood glucose metabolism in the perioperative period as a consequence of an intraoperative acute stress state, blood loss and transfusions, the reperfusion phase, use of glucocorticoids and catecholamines.
Results from previous studies pointed the hyperglycaemia among LT recipient as a frequent complication, 94% of them presented it at least once in the transplantation's postoperative period.
