ABSTRACT

Objective:To investigate the effect of continuous renal replacement therapy on sepsis complicated with acute renal injury and its influence on cytokines and renal function.Methods:From January 2017 to October 2019, 82 patients with sepsis and acute renal injury admitted to the People's Hospital of Jiangshan were divided into control group and observation group according to the random digital table, with 41 cases in each group.The control group was given routine treatment, and the observation group was treated with continuous veno venous hemofiltration(CVVH) on the basis of the control group.The course of treatment in both groups was 5 days.The time of ICU stay and mechanical ventilation, Marshall score, acute physiology and chronic health status scoreⅡ(APACHEⅡ), cytokines and renal function were compared before and after treatment.Results:The ICU stay time[(13.25±1.97)d] and mechanical ventilation time[(11.83±2.43)d] in the observation group were shorter than those in the control group[(11.83±2.43)d and (16.78±1.85)d]( t=9.092, 10.378, all P<0.05). After treatment, the Marshall organ dysfunction score[(5.78±0.81)points] and APACHEⅡ score[(15.40±1.62)points] in the observation group were lower than those in the control group[(7.19±0.67)points and (21.25±3.25)points]( t=8.589, 10.315, all P<0.05). The serum levels of PCT[(7.68±2.10)μg/L] and CRP[(45.41±10.20)mg/L] in the observation group were lower than those in the control group[(13.76±1.78)μg/L and (109.87±12.76)mg/L]( t=14.142, 11.320, 25.266, all P<0.05). The serum levels of BUN[(4.62±0.38)nmol/L] and Scr[(25.45±5.17)μmol/L] in the observation group were lower than those in the control group[(13.79±0.43)nmol/L and (68.79±4.15)μmol/L]( t=20.011, 18.421, all P<0.05). Conclusion:The effect of continuous renal replacement therapy on sepsis combined with acute renal injury is good, which can significantly reduce the inflammatory response of cells and improve the renal function of patients.

ABSTRACT

Objective Calcitonin gene-related peptide (CGRP), neurotensin (NT) and atrial natriuretic polypeptide (ANP) have strong vaso-dilating and positive inotropic action, whereas neuropeptide Y (NPY) and endothelin (ET) have vaso-constricting effect. They all have profound effects on hemodynamics. The purpose of this study was to examine the changes in the 5 neuropeptides in elderly hypertensive patients under general anesthesia.Methods The control group comprised eight men and six women without hypertension with a mean age of (69?8)yr. The hypertension group included nine men and five women with a mean age of (71?9)yr. The patients in the hypertension group had different degrees of myocardial hypertrophy and ST-T changes. All 28 patients underwent upper abdominal surgery. Anesthesia was induced with propofol 2mg?kg -1 and fentanyl 2?g?kg -1 and intubation was facilitated with succinylcholine 2mg?kg -1. The patients were mechanically ventilated after intubation. Anesthesia was maintained with 50% N 2O and enflurane or isoflurane inhalation supplemented with intermittent doses of vecuronium. Venous blood samples were taken before anesthesia, 3min after intubation, 60 min after start of surgery, at the end of surgery and 24 h after operation for determination of plasma levels of CGRP, NT, ANP, NPY and ET by radioimmunoassay.Results In hypertension group plasma level of ANP decreased and NPY increased significantly at the end of operation and 24 h after operation (P
