RESUMO
Objective To study the influence of clinical nutritional support on the effects of mechanical ventilation (MV), and to find the factors affecting the outcome of patients undergoing MV. Methods A case-control study was conducted. The clinical data of 235 patients undergoing MV admitted to intensive care unit (ICU) of Tongde Hospital of Zhejiang Province from January 2015 to June 2017 were retrospectively analyzed. The patients were divided into two groups according to whether weaning successfully within 7 days. The clinical data of patients in the two groups were collected including gender, age, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, underlying disease, nutritional indicators, nutritional support, and complications. The outcome of withdrawal within 7 days was served as a dependent variable, all observed indicators were served as independent variables, and Logistic regression analysis was carried out to screen the influencing factors of the weaning results within 7 days. Results 235 patients undergoing MV were enrolled, 128 patients were successfully withdrawn within 7 days, and 107 were unsuccessfully withdrawn. Compared with the successful weaning group, the patients of weaning failure group were older, and had higher APACHEⅡ score and lower albumin (Alb) and hemoglobin (Hb), more patients with internal medical underlying diseases and receiving parenteral nutrition (PN) and mixed nutrition, and the incidences of secondary infection, vomiting, abdominal distension, abnormal bowel sound, gastric retention, and diarrhea were higher. However, there was no statistical significance in gender between the two groups. The variables of statistical significance in univariate analysis were enrolled in the multifactor analysis model showing that age [odds ratio (OR) = 1.269, 95% confidence interval (95%CI) = 1.119-1.439, P < 0.001], APACHEⅡ score (OR = 1.643, 95%CI = 1.423-1.897, P < 0.001), internal medical underlying diseases (OR = 6.298, 95%CI = 4.012-9.887, P < 0.001), secondary infection (OR = 8.323, 95%CI = 2.568-26.975, P < 0.001), abdominal distension (OR = 3.368, 95%CI = 1.586-7.152, P = 0.002), abnormal bowel sounds (OR = 2.856, 95%CI = 1.215-6.713, P = 0.017), gastric retention (OR = 1.996, 95%CI = 1.183-3.368, P = 0.010), diarrhea (OR = 3.035, 95%CI = 1.337-6.890, P = 0.008) were risk factors for unsuccessful weaning,and compared with PN, enteral nutrition (EN; OR = 0.191, 95%CI = 0.098-0.372, P < 0.001) and mixed nutrition (OR = 0.375, 95%CI = 0.150-0.938, P = 0.037) were protective factors of successful weaning. The gender, Alb and Hb before and after MV, vomiting, gastrointestinal hemorrhage were not associated with weaning outcome within 7 days. Conclusions Elder, high APACHEⅡ score, internal medical underlying diseases, or secondary infection, abdominal distension, abnormal bowel sounds, gastric retention, diarrhea were risk factors of weaning failure within 7 days in patients undergoing MV. Compared with PN, EN and mixed nutrition were protective factors for successful weaning. For patients undergoing MV, EN should be performed early in the case of full recovery, hemodynamic stability, and serious metabolic disorders.
RESUMO
Objective To investigate the effect of continuous veno-venous hemofiltration (CVVH) on pulmonary vascular permeability in the early stage of septic shock.Methods Fifty-one patients of septic shock admitted in intensive care unit of the First Affiliated Hopsital of Medical College,Zhejiang University between June 2010 and December 2011 were randomized into two groups by simple random method.Routine treatment was carried out to patients in group A,and routine treatment plus CVVH to patients in group B in the first 72 hours.Repeated respiratory mechanic hemodynamic measurements were done at baseline (Tb) before treatment,at 48 hours (T48) and 72 hours (T72) after the treatment.Pulmonary compliance (Cst),platform pressure (Pplat),oxygenation index (PaO2/FiO2),extravascular lung water index (EVLWI) and E-selectin determined at each time point were recorded in two groups.Results (1) Pplat were decreased significantly after treatment in two groups,and the Pplat in group B were all lower than those in group A at T48 and T72 (t =2.215,P ＜ 0.05 ; t =4.266,P ＜ 0.01).Cst were elevated after treatment in two groups,and Cst in group B were all higher than those in group A at T48 and T72 (t =2.516,P ＜0.05 ; t =3.052,P ＜ 0.01).(2) Compared to before treatment,PaO2/FiO2 increased significantly after treatment in two groups,and PaO2/FiO2 in group B were all higher than those in group A at T48 and T72 (t =2.732,P ＜0.01 ; t =3.511,P ＜0.01).(3) EVLWI were decreased significantly after treatment in two groups,and the EVLWI in group B were all lower than those in group A at T48 and T72 (t =2.597,P ＜0.05; t =2.125,P ＜ 0.05).ITBVI,CI,SVRI and MAP did not change over time in two groups compared with those at Tb (all P ＞ 0.05).(4) E-selectin were decreased significantly after treatment in two groups,and the E-selectin in group B were all lower than those in group A at T48 and T72 (t =2.154,P ＜0.05 ; t =3.581,P ＜ 0.01).Conclusion CVVH in early stage of septic shock can improve pulmonary vascular permeability and oxygenation,increase Cst,and decline EVLWI,with neither increased hemodynamics.
