The aim of our study was to assess the association between the macrohemodynamic profile and sepsis induced acute kidney injury (AKI). We also investigated which minimally invasive hemodynamic parameters may help identify patients at risk for sepsis-AKI. We included 71 patients with sepsis and septic shock. We performed the initial fluid resuscitation using local protocols and continued to give fluids guided by the minimally invasive hemodynamic parameters. We assessed the hemodynamic status by transpulmonary thermodilution technique. Sequential organ failure assessment (SOFA score) (AUC 0.74, 95% CI 0.61–0.83, p < 0.01) and cardiovascular SOFA (AUC 0.73, 95% CI 0.61–0.83, p < 0.01) were found to be predictors for sepsis-induced AKI, with cut-off values of 9 and 3 points respectively. Persistent low stroke volume index (SVI) ≤ 32 mL/m2/beat (AUC 0.67, 95% CI 0.54–0.78, p < 0.05) and global end-diastolic index (GEDI) < 583 mL/m2 (AUC 0.67, 95% CI 0.54–0.78, p < 0.05) after the initial fluid resuscitation are predictive for oliguria/anuria at 24 h after study inclusion. The combination of higher vasopressor dependency index (VDI, calculated as the (dobutamine dose × 1 + dopamine dose × 1 + norepinephrine dose × 100 + vasopressin × 100 + epinephrine × 100)/MAP) and norepinephrine, lower systemic vascular resistance index (SVRI), and mean arterial blood pressure (MAP) levels, in the setting of normal preload parameters, showed a more severe vasoplegia. Severe vasoplegia in the first 24 h of sepsis is associated with a higher risk of sepsis induced AKI. The SOFA and cardiovascular SOFA scores may identify patients at risk for sepsis AKI. Persistent low SVI and GEDI values after the initial fluid resuscitation may predict renal outcome.
Background and Objectives: Surgical wound analgesia has been analyzed in many studies, but few have focused on its relationship with inflammatory markers. As such, we aimed to determine the influence of analgesic surgical wound infiltration in open colorectal surgery on the seric levels of pro- and anti-inflammatory markers and the associated efficacy in postoperative pain control. Materials and Methods: Forty patients who underwent open colorectal surgery were prospectively randomized: group 0, epidural analgesia; group 1, intravenous analgesia (control), group 2, preincision and prelaparoraphy infiltration; and, group 3, prelaparoraphy infiltration. Wound infiltration was performed with ropivacaine. We analyzed the levels of IL-6 and IL-10 cytokines before and 6 h after surgery and their correlation with pain scores. Results: The postoperative Il-6 levels were significantly lower in group 0 than in the control (p = 0.041). The postoperative Il-10 levels were significantly higher in group 3 (p = 0.029) than in the control. Six hours after the operation, the pain scores were significantly lower in all groups than in the control (p = 0.005, p = 0.022, and p = 0.017 for groups 0, 2, and 3, respectively). Pain scores were significantly correlated with Il-10 levels in group 2 (p = 0.047); in group 3, IL-10 levels directly correlated with those of Il-6 (p = 0.026). Conclusions: The analgetic effect of preincisional and prelaparoraphy analgetic infiltration was efficient. The analgetic infiltration of the surgical wound prior to closure stimulates both the inflammatory activator and regulator interleukins.
Background and Objectives: The technique of complete mesocolic excision (CME) for colonic cancer is being advocated to improve the local control of the disease and increase the long-term survival. However, even with an open approach, CME is a complex technique and has not yet been adopted as standard care. Laparoscopy has been proven to bring significant advantages to colorectal surgery but performing a laparoscopic CME (Lap-CME) for colonic cancer is even more technically demanding than CME in open surgery. The purpose of this study is to evaluate whether Lap-CME can be offered as a standard procedure for patients with colonic cancer and to compare the results with those obtained after a conventional, open technique. Materials and methods: This study included 100 consecutive patients with colonic cancer, who were operated on by the same surgical team using a standardized medial-to-lateral open or laparoscopic complete mesocolic excision technique. The perioperative data was prospectively recorded in a database and retrospectively analyzed with the aim of identifying the proportion of patients that received Lap-CME, to evaluate the success rate of the procedure and to identify whether there are differences in the oncological quality of CME between the laparoscopic and open surgery groups. Results: Most of the patients enrolled in this study were in the advanced stages of the disease, with the incidence of pT3 tumors being 67% and the mean tumor size averaging 4.5 cm. Laparoscopic CME was performed in 39% of cases overall, with 41.4% being right colectomies, 42.5% being left colectomies and 16.1% being transverse colectomies. All of the parameters relevant to the oncological quality of resection, namely total lymph node count, resection margins, or the completeness of resection, were similar between the open and laparoscopic groups both when analyzed for the entire cohort or when analyzed for specific subgroups according to the tumor location (right, transverse, or left colon) or stage of the disease (pT3 or stage III). Conclusions: Laparoscopic complete mesocolic excision for colonic cancer can be offered as a standard procedure by experienced surgical teams in carefully selected patients and provides oncological results similar to those obtained with open surgery.
