ObjectiveTo systematically review the predictors of enteral nutrition feeding intolerance in critically ill patients. MethodsThe PubMed, Web of Science, Cochrane Library, Embase, CNKI, WanFang Data, VIP and CBM databases were searched to collect relevant observational studies from the inception to 6 August, 2022. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.4 software. ResultsA total of 18 studies were included, including 28 847 patients. The results of the meta-analysis showed that gender, age, severity of illness, hypo-albuminemia, length of stay, postpyloric feeding, mechanical ventilation and mechanical ventilation time, use of prokinetics, use of sedation drugs, use of vasoactive drugs and use of antibiotics were predictors of enteral nutrition feeding intolerance in critically ill patients, among which postpyloric feeding (OR=0.46, 95%CI 0.29 to 0.71, P<0.01) was a protective factor. ConclusionAccording to the influencing factors, the medical staff can formulate a targeted enteral nutrition program at the time of admission to the ICU to reduce the occurrence of feeding intolerance. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
Methods Sixty-six postoperative patients with gastric cancer combined diabetes were divided into 3 groups according to the balanced principle. In the frist group (FD group), FD was the nutrition preparation for 21 patients. In the second group (fresubin group), fresubin and the ordinary insulin injection were the nutrition preparation for 21 patients. In the third group (TPN group), the nutrition preparation came from TPN and the ordinary insulin injection for 24 patients. FD, fresubin or TPN were given at 24 h after operation, the levels of blood glucose for empty stomach, after meal (enteral nutrition or TPN) and the common complications compared among 3 groups of postoperative patients. Results ① In FD group, the levels of blood glucose of postoperative empty stomach and after enteral nutrition were stable with little fluctuation and no insulin was needed with 1 case of hyperglycemia (4.8%). In fresubin group and TPN group, the levels of blood glucose of postoperative empty stomach and after enteral nutrition or TPN were unstable with big fluctuation, with 6 cases (28.6%) and 8 cases (33.3%) of hyperglycemia, 5 cases (23.8%) and 6 cases (25.0%) of hypoglycemia in fresubin group and TPN group, respectively. Compared with fresubin group and TPN group, the rate of pathoglycemia was lower in FD group, the difference had statistical significance separately (Plt;0.05); There was no significant difference between fresubin group and TPN group (Pgt;0.05). ② The rates of infection of incisional wound in FD group (4.8%) and fresubin group (23.8%) were lower than that of TPN group (33.3%), there was significant difference among 3 groups (Plt;0.05); The time of passage of gas by anus in FD group and fresubin group were shorter than that in TPN group (Plt;0.05); There was no significant difference between FD group and fresubin group (Pgt;0.05). There were no significant differences of the rates of abdominal distension or diarrhea among 3 groups (Pgt;0.05). Conclusion Regarding postoperative patients with gastric cancer combined diabetes, in the early time field test group of the nutrition preparation, FD is better than fresubin or TPN, which does not increase the risk of the blood glucose change and have few complications.
ObjectiveTo summary the effect of parenteral nutrition combined with enteral nutrition on patients with severe acute pancreatitis.
MethodsThe clinical data of 200 patients with severe acute pancreatitis admitted in our hospital in recent 10 years were retrospectively analyzed. Of which 88 cases were treated by traditional nutritional support therapy (traditional nutrition group), the rest of 112 cases of patients with early parenteral nutrition to later period gradually combined with enteral nutrition comprehensive nutritional support strategy (comprehensive nutrition group).
ResultsThe APACHEⅡscores and serum level of C-reactive protein (CRP) of patients in comprehensive nutrition group were significantly lower than patients in traditional nutrition group (P < 0.05), while the serum albumin level was significantly higher than that of traditional nutrition group (P < 0.05). In the incidence of complications and mortality, the average length of stay and total cost of comprehensive nutrition group were significantly lower than patients with traditional nutrition group (P < 0.05), the cure rate was significantly higher than that of traditional nutrition group (P < 0.05).
ConclusionThe combination of parenteral nutrition and enteral nutrition of nutrition support model not only can shorten the duration of symptoms but also alleviate the burden of patients and reduce complications and mortality.
Objective To explore the protective effect of early enteral nutrition on intestinal mucosa barrier in patients with esophageal carcinoma after operation. Methods Fifty six patients with esophageal carcinoma whose weight decreased more than 20% before operation in three months were divided into enteral nutrition group ( n =30) and parenteral nutrition group ( n =26). Plasma concentration of lipopolysaccharide(LPS), tumor necrosis factor (TNF), gastrin, glutamine, and ratio of lactulose and mannitol (L/M) were measured on the 1st, 4th, 8th day after operation respectively. Results Weight loss and infectious complication in enteral nutrition group were less than those in parenteral nutrition group after operation ( P lt;0.01, 0.05). On the 4th and 8th day after operation,the level of LPS,TNF, and L/M were lower in enteral nutrition group than those in parenteral nutrition group ( P lt;0 01), the values of gastrin and glutamine were higher in enteral nutrition group than those in parente...更多ral nutrition group ( P lt;0 01). Conclusion Enteral nutrition can protect the intestinal mucosa barrier and decrease infectious complication after operation.
Objective To investigate the safety and efficiency of a blood glucose control method in diabetic patients with gastrointestinal neoplasm who were subjected to postoperative early enteral nutrition (EEN). Methods Thirty-seven diabetic patients with gastrointestinal neoplasm received enteral nutriment——Glucerna SR through nasojejunal tubes 24 hours after operation. The blood glucose level was safely controlled through injecting insulin intravenously and subcutaneously. Meanwhile, any change of blood and urine glucose level was monitored and the indexes representing the levels of nutrition, biochemistry and immunity were measured before the implementation of EN, 5 d and 8 d of EN after operation, respectively. Results All the patients were able to bear EEN and there was no severe complications occurred. Significant increase of serum levels of albumin, prealbumin and transferrin were observed after EEN support （P＜0.05）, as well as the serum levels of IgG， IgA and IgM （P＜0.01）. However, body weight， HGB and the serum levels of ALT and TBIL showed no significant changes （Pgt;0.05）. There were 81.1%（30/37） of patients whose blood glucose levels were controlled steadily within the range of (7.8±1.1) mmol/L. Conclusion Injecting insulin intravenously and subcutaneously after operation may be a safe and effective method to control blood glucose level. And the postoperative implementation of EEN can be considered as the first choice of nutrition support for diabetic patients with gastrointestinal neoplasm.
ObjectiveTo explore influence of different nutritional approaches on liver function in patients after esophagectomy.
MethodsA total of 160 patients with esophageal cancer who underwent surgical treatment were divided into a enteral nutrition (EN) group and a total parenteral nutrition (TPN) group according to different medical staff. There were 80 patients in each group. Two and 7 days postoperatively, albumin (ALB), prealbumin (PA), alanine aminotransferase (ALT) and total bilirubin (TB) of the 2 groups were examined to evaluate liver function.
ResultsAbnormities in liver function (ALB, PA, ALT, TB) was common phenomenon in esophageal cancer patients, but there was no statistical difference in ALB, PA, ALT, TB on the 2nd postoperative day between the EN group and the TPN group (P > 0.05). On the 7th postoperative day, liver functions were improved than those on the 2nd postoperative day in the two groups. And frequencies of liver function abnormity in the EN group were significantly lower than those in the TNP group (P < 0.05).
ConclusionCompared with TPN, EN has advantages in facilitating hepatic protein synthesis and recovery of liver function after esophagectomy.
Objective To investigate the influence on the postoperative recovery for giving either total parenteral nutrition （TPN） or early enteral nutrition (EEN) to patients with gastric cancer after total gastrectomy. Methods Eighty-six patients with gastric cancer undergone total gastrectomy were divided into TPN group (n=31) and EEN group (n=55). Patients in TPN group received TPN support via vena cava (internal jugular vein or subclavian vein), while patients in EEN group received early feeding through the naso-intestinal tube, which was placed during operation, and volume of enteral nutrition (fresubin) was increased daily, full enteral nutrition was expected on day 3-5. Nutrition status after operation, postoperative plasma albumin (Alb), the time of passing gas or stool, the time of oral intake, hospital stay and any postoperative complications were recorded and analyzed. Results There were no significant differences between two groups (Pgt;0.05) in postoperative plasma Alb level, the time of passing gas or stool, postoperative complications rate or hospital stay. However, in the TPN group, the time of oral intake was shorter than that in EEN group (P=0.004). Conclusions Both TPN and EEN are the suitable nutritional methods for patients with gastric cancer after total gastrectomy, and with no detectable difference. For patients with high risk, such as severe malnutrition, naso-intestinal tube should be placed for EEN.
Objective To study effects of enteral immunonutrition and econutrition on intestinal mucosa barrier function in wounded rats. Methods Forty Wistar rats were randomly divided into four groups, with ten rats in each group 〔ie.control group, enteral nutrition (EN) group, enteral immunonutrition (EIN) group and enteral econutrition (EEN) group〕. After gastrostomy, rats in each group were treated with the isocaloric and isonitrogenous nutritional formulas for 7 days, respectively. The morphology of ileum membrane was studied, and the quantities of IgA+, CD3+, CD4+ and CD8+ cells (each HP) of ileum membrane were determined. Results The villus height, crypt depth, mucosal thickness (except EN group) and villus surface area of ileum were increased in EN, EIN and EEN group compared with control group (P＜0.05), but there was no significant difference among the former three groups (Pgt;0.05). The numbers of IgA+, CD3+, CD4+ and CD8+ cells were increased in EN, EIN and EEN group compared with control group (P＜0.05), and those numbers in EN group were lower than those in EIN and EEN group (P＜0.05). Conclusion EIN and EEN may improve intestine mechanical barrier function and promote restoration of small intestine mucous membrane barrier function in rats. EIN and EEN also improve intestine immune barrier function and strengthen its immune function.
ObjectiveTo summarize the experiences of application and nursing measures of three-lumen gastrojejunal tube for enteral nutrition in postoperative patients with gastric carcinoma.
MethodsWe analyzed the clinical data of 60 gastric cancer patients undergoing treatment with three-lumen gastrojejunal tube after surgery between June and September 2012. And then we summarized the nursing experiences including fixation and flushing of the tube, plugging disposal, management of the nutrition temperature, and infusion speed choice.
ResultsPostoperative nutritional status of all the 60 patients were improved. Their plasma albumin level reached (34.58±5.29) g/L, plasma hemoglobin reached the level of (113.90±19.12) g/L, and score of nutrition risk screening 2002 reached 3.47±0.71. Meanwhile, earlier recovery of enteric function made shorter average hospitalization. Decreasing use of parenteral nutrition avoided related complications.
ConclusionApplication of the three-lumen gastrojejunal tube in postoperative patients with gastric carcinoma for enteral nutrition can improve their nutritional status and promote their recovery at an early time.
Objective To evaluate the clinical curative effect of early enteral nutrition （EN） in gastric cancer patients after operation and its safety. Methods One hundred and eighty patients with gastric cancer diagnosed and underwent surgical treatment in gastrointestinal surgery center， West China Hospital from February 2011 to December 2011 were studied prospectively， who were randomly divided into EN group （n=91） and parenteral nutrition （PN） group （n=89）. The nutrition state， rehabilitation， hospital stay， cost of nutrition in hospital， and complications were observed. Results ①According to the postoperative serum nutrition index， there were no significant differences in the prealbumin， hemoglobin， and ratio of albumin to globulin in two groups （P＞0.05）， but the albumin level in the EN group was significantlyhigher than that in the PN group （P=0.047）. ②According to the postoperative rehabilitation index， the first ambulation time （P=0.011）， first intake time （P=0.000）， first nasogastric tube away time （P=0.013）， first drainage tube away time （P=0.021）， and first urinary catheter away time （P=0.002） in the EN group were significantly shorter than those in the PN group. The difference of the first anus exhaust time was not statistically significant in two groups （P=0.083）. ③The cost of nutrition in hospital in the EN group was significantly less than that in the PN group （P=0.017）. The postoperative hospital stay and total complication rate were not significant differences in two groups （P＞0.05）. Conclusion Early postoperative EN is effective， economic， practical， which might be superior to PN.
