Abstract
Introduction: Cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) has been established as an effective treatment for peritoneal cancer (PC). However, this kind of combination therapy is associated with a high lactate level. Moreover, studies have suggested that the rate of complications early after surgery directly increased with elevated lactate levels. Glucose-insulin-potassium (GIP), a potent cardioprotective intervention, has been demonstrated to adjust blood glucose (BG) levels and reduce lactate levels. However, the insulin-glucose ratio should be adjusted according to the surgery performed. Here, we aimed to evaluate the advantages of using modified GIP during CRS/HIPEC to reduce the lactate level at the end of surgery and further reduce the incidence of early postoperative complications.
Methods and analysis: The modified GIP versus conventional management during surgery study is a single-center, randomized, single-blinded outcome assessment clinical trial of 80 patients with PC who are between 18 and 64 years old and undergoing CRS/HIPEC. Participants will be randomly allocated to receive modified GIP or conventional treatment (1:1). The primary outcome will be the plasma lactate level at the end of surgery. The secondary outcomes will include the highest levels and fluctuation ranges of lactate and BG during surgery, extubation time, APACHE-II score 24 h after surgery, postoperative defecation and exhaust time, postoperative lactate clearance time, postoperative liver and kidney function, incidence of complications within 7 days after surgery, length of intensive care unit stay (LIS), length of hospital stay (LHS), and total cost of hospitalization.
Ethics and dissemination: The trial protocol was approved by the Scientific Research Ethics Committee of Beijing Shijitan Hospital Affiliated with Capital Medical University, approval number sjtky11-1x-2022(118). The results will be published in international peer-reviewed journals.
Trial registration: ChiCTR2200057258. Registered on March 5, 2022.
期刊介绍：
Trials is an open access, peer-reviewed, online journal that will encompass all aspects of the performance and findings of randomized controlled trials. Trials will experiment with, and then refine, innovative approaches to improving communication about trials. We are keen to move beyond publishing traditional trial results articles (although these will be included). We believe this represents an exciting opportunity to advance the science and reporting of trials. Prior to 2006, Trials was published as Current Controlled Trials in Cardiovascular Medicine (CCTCVM). All published CCTCVM articles are available via the Trials website and citations to CCTCVM article URLs will continue to be supported.
