Impact of early enteral nutrition on in-hospital mortality in patients with hypertensive intracerebral hemorrhage

Impact of early nutrition and feeding route on clinical outcomes of neurocritically ill patients

Early proper nutritional support is important to critically ill patients. Nutritional support is also associated with clinical outcomes of neurocritically ill patients. We investigate whether early nutrition is associated with clinical outcomes in neurocritically ill patients. This was a retrospective, single-center, observational study including neurosurgical patients who were admitted to the intensive care unit (ICU) from January 2013 to December 2019. Patients who started enteral nutrition or parenteral nutrition within 72 hours after ICU admission were defined as the early nutrition group. The primary endpoint was in-hospital mortality. The secondary endpoint was an infectious complication. Propensity score matching (PSM) and propensity score weighting overlap weights (PSOW) were used to control selection bias and confounding factors. Among 1,353 patients, early nutrition was performed in 384 (28.4%) patients: 152 (11.2%) early enteral nutrition (EEN) and 232 (17.1%) early parenteral nutrition (EPN). In the overall study population, the rate of in-hospital mortality was higher in patients with late nutrition than in those with early nutrition (P<0.001). However, there was no significant difference in in-hospital mortality and infectious complications incidence between the late and the early nutrition groups in the PSM and PSOW adjusted population (all P>0.05). In the overall study population, EEN patients had a low rate of in-hospital mortality and infectious complications compared with those with EPN and late nutrition (P<0.001 and P = 0.001, respectively). In the multivariable analysis of the overall, PSM adjusted, and PSOW adjusted population, there was no significant association between early nutrition and in-hospital mortality and infectious complications (all P>0.05), but EEN was significantly associated with in-hospital mortality and infectious complications (all P<0.05). Eventually, early enteral nutrition may reduce the risk of in-hospital mortality and infectious complications in neurocritically ill patients.

Comparison of nutritional effectiveness and complication rate between early nasojejunal and nasogastric tube feeding in patients with an intracerebral hemorrhage

BACKGROUND

This study aimed to compare nutritional effectiveness and complication rate between early nasojejunal and nasogastric tube feeding in patients with an intracerebral hemorrhage.

METHODS

This was a retrospective study. Eighty patients with an intracerebral hemorrhage were divided into a nasojejunal and a nasogastric tube feeding group. Feeding tubes were placed within 6 h after admission, and enteral feeding began within 2 h after tube placement. The nutritional status and complication rate of the 2 groups were compared before and 2 and 4 weeks after beginning feeding.

RESULTS

Serum prealbumin, serum albumin, and hemoglobin levels were significantly higher in the nasojejunal tube feeding group than in the nasogastric tube feeding group at 2 and 4 weeks after beginning feeding (all, p < 0.05). The incidence of gastric retention, pulmonary aspiration, and pneumonia were lower in the early nasojejunal tube feeding group than in the early nasogastric tube feeding group (all, p < 0.05). There was no significant difference in the incidence of diarrhea between the 2 groups.

CONCLUSION

Compared with early nasogastric feeding, early nasojejunal feeding provides better nutritional effectiveness and a lower incidence of gastric retention, pulmonary aspiration, and pneumonia in patients with an intracerebral hemorrhage.

Early Enteral Combined with Parenteral Nutrition Treatment for Severe Traumatic Brain Injury: Effects on Immune Function, Nutritional Status and Outcomes

Objective To compare the conjoint effect of enteral nutrition (EN) and parenteral nutrition (PN) with single EN or PN on immune function, nutritional status, complications and clinical outcomes of patients with severe traumatic brain injury (STBI). Methods A prospective randomized control trial was carried out from January 2009 to May 2012 in Neurological Intensive Care Unit (NICU). Patients of STBI who met the enrolment criteria (Glasgow Coma Scale score 6~8; Nutritional Risk Screening ≥3) were randomly divided into 3 groups and were admi- nistrated EN, PN or EN+PN treatments respectively. The indexes of nutritional status, immune function, complications and clinical outcomes were examined and compared statistically. Results There were 120 patients enrolled in the study, with 40 pationts in each group. In EN+PN group, T lymthocyte subsets CD3+%, CD4+%, ratio of CD3+/CD25+, ratio of CD4+/CD8+, the plasma levels of IgA, IgM, and IgG at 20 days after nutritional treatment were significantly increased compared to the baseline(t=4.32-30.00, P<0.01), and they were significantly higher than those of PN group (t=2.44-14.70; P<0.05,or P<0.01) with exception of CD4+/CD8+, higher than those of EN group (t=2.49-13.31, P<0.05, or P<0.01) with exceptions of CD3+/CD25+, CD4+/CD8+, IgG and IgM. For the nutritional status, the serum total protein, albumin, prealbumin and hemoglobin were significantly higher in the EN (t=5.87-11.91; P<0.01) and EN+PN groups (t=6.12-13.12; P<0.01) than those in PN group after nutrition treatment. The serum prealbumin was higher in EN+PN group than that in EN group (t=2.08; P<0.05). Compared to the PN group, the complication occurrence rates of EN+PN group were significantly lower in stress ulcer (22.5% vs. 47.5%; χ²= 8.24, P<0.01), intracranial infection (12.5% vs 32.5%;χ²= 6.88, P<0.01) and pyemia (25.0% vs. 47.5%; χ²= 6.57, P<0.05). Compared to the EN group, the complication occurrence rates of EN+PN group were significantly lower in aspirated pneumonia (27.5% vs. 50.0%; χ²= 6.39, P<0.05), hypoproteinemia (17.5% vs. 55.0%; χ²= 18.26, P<0.01) and diarrhea (20.0% vs. 60.0%; χ²= 20.00, P<0.01). The EN+PN group also had significant less length of stay in NICU (t=2.51, 4.82; P<0.05, P<0.01), number of patients receiving assisted mechanical ventilation (χ²= 6.08, 12.88; P<0.05, P<0.01) and its durations (t=3.41, 9.08; P<0.05, P<0.01), and the death rate (χ²=7.50, 16.37; P<0.05, P<0.01) than those of EN or PN group. Conclusion Early EN+PN treatment could promote the recovery of the immune function, enhance nutritional status, decrease complications and improve the clinical outcomes in patients with severe traumatic brain injury.

Early enteral nutrition in critically ill patients: ESICM clinical practice guidelines

Purpose

To provide evidence-based guidelines for early enteral nutrition (EEN) during critical illness.

Methods

We aimed to compare EEN vs. early parenteral nutrition (PN) and vs. delayed EN. We defined “early” EN as EN started within 48 h independent of type or amount. We listed, a priori, conditions in which EN is often delayed, and performed systematic reviews in 24 such subtopics. If sufficient evidence was available, we performed meta-analyses; if not, we qualitatively summarized the evidence and based our recommendations on expert opinion. We used the GRADE approach for guideline development. The final recommendations were compiled via Delphi rounds.

Results

We formulated 17 recommendations favouring initiation of EEN and seven recommendations favouring delaying EN. We performed five meta-analyses: in unselected critically ill patients, and specifically in traumatic brain injury, severe acute pancreatitis, gastrointestinal (GI) surgery and abdominal trauma. EEN reduced infectious complications in unselected critically ill patients, in patients with severe acute pancreatitis, and after GI surgery. We did not detect any evidence of superiority for early PN or delayed EN over EEN. All recommendations are weak because of the low quality of evidence, with several based only on expert opinion.

Conclusions

We suggest using EEN in the majority of critically ill under certain precautions. In the absence of evidence, we suggest delaying EN in critically ill patients with uncontrolled shock, uncontrolled hypoxaemia and acidosis, uncontrolled upper GI bleeding, gastric aspirate >500 ml/6 h, bowel ischaemia, bowel obstruction, abdominal compartment syndrome, and high-output fistula without distal feeding access.

Medical management of intracerebral haemorrhage

The global burden of intracerebral haemorrhage (ICH) is enormous. Developing evidence-based management strategies for ICH has been hampered by its diverse aetiology, high case fatality and variable cooperative organisation of medical and surgical care. Progress is being made through the conduct of collaborative multicentre studies with the large sample sizes necessary to evaluate therapies with realistically modest treatment effects. This narrative review describes the major consequences of ICH and provides evidence-based recommendations to support decision-making in medical management.

Critical care management of intracerebral hemorrhage

Primary, spontaneous intracerebral hemorrhage (ICH) confers significant early mortality and long-term morbidity worldwide. Advances in acute care including investigative, diagnostic, and management strategies are important to improving outcomes for patients with ICH. Physicians caring for patients with ICH should anticipate the need for emergent blood pressure reduction, coagulopathy reversal, cerebral edema management, and surgical interventions including ventriculostomy and hematoma evacuation. This article reviews the pathogenesis and diagnosis of ICH, and details the acute management of spontaneous ICH in the critical care setting according to existing evidence and published guidelines.

Effect of sequential enteral nutrition on nutritional status and prognosis in patients with hypertensive intraventricular hemorrhage

AIM: To investigate the effect of sequential enteral nutrition on nutritional status and prognosis in patients with hypertensive intraventricular hemorrhage.

METHODS: A retrospective analysis of 54 patients with hypertensive intraventricular hemorrhage treated at our hospital from September 2011 to September 2013 was performed. Depending on the mode of nutrition, the patients were divided into either an experimental group (n = 29) or a control group (n = 25). The experimental group received sequential enteral nutrition from the third day after admission, while the control group received isocaloric amount of liquid diet and parenteral nutrition. On the 2nd and 16th d after admission, neurological scores were tested using the National Institutes of Health Stroke Scale (NIHSS), and hemoglobin, albumin, transferrin and lymphocyte count were recorded. The incidences of diarrhea, gastric retention, stress-induced gastrointestinal bleeding and pulmonary infection were observed. The hospitalization time of each patient was counted.

RESULTS: On the 2nd d after admission, there were no significant differences in hemoglobin, albumin, transferrin or lymphocyte count between the experimental group and the control group. On the 16th d, hemoglobin, albumin, transferrin and lymphocyte count in the experimental group were significantly higher than those in the control group (132.15 g/L ± 14.39 g/L vs 117.69 g/L ± 10.73 g/L, 39.65 g/L ± 7.88 g/L vs 32.15 g/L ± 5.48 g/L, 2.14 g/L ± 0.21 g/L vs 1.80 g/L ± 0.45 g/L, 2.13 × 10⁹ ± 0.39 × 10⁹vs 1.79 × 10⁹ ± 0.33 × 10⁹, P < 0.05 for all). The incidences of diarrhea and gastric retention showed no significant differences between the experimental group and the control group. The incidences of stress-induced gastrointestinal bleeding and pulmonary infection in the experimental group were significantly lower than those in the control group (3.45% vs 24.00%, 6.90% vs 32.00%, P < 0.05 for all). The hospitalization time in the experimental group was significantly less than that in the control group (23.92 d ± 3.76 d vs 26.96 d ± 5.53 d, P < 0.05).

CONCLUSION: Sequential enteral nutrition can effectively improve nutritional status, reduce the incidences of stress-induced gastrointestinal bleeding and pulmonary infection, promote neural function recovery, and reduce hospitalization in patients with hypertensive intraventricular hemorrhage.

Factors associated with severity on admission and in-hospital mortality after primary intracerebral hemorrhage in China

BACKGROUND AND PURPOSE

Of the stroke types, intracerebral hemorrhage is the most debilitating and fatal. The aim of the current study was to determine factors that influence the severity and in-hospital mortality after primary intracerebral hemorrhage.

METHODS

Data were collected retrospectively on 1268 patients with primary intracerebral hemorrhage admitted to stroke units at participating hospitals in Guangzhou between January 2005 and August 2008. Logistic regression analysis was used to determine factors associated with severity on admission and in-hospital mortality.

RESULTS

Of the 1268 patients, 20·4% were reported to have a severe stroke on admission, and the in-hospital mortality rate was 12·5%. Severity on admission was strongly associated with Glasgow Coma Scale score on admission (odds ratio = 0·89, 95% confidence interval 0·85-0·94) and hematoma location. Notably, basal ganglia hemorrhages were associated with increased severity (odds ratio = 1·40, 95% confidence interval 1·03-1·90), and cerebellar hemorrhages were associated with reduced severity (odds ratio = 0·29, 95% confidence interval 0·10-0·84). In-hospital mortality was not only correlated with Glasgow Coma Scale score on admission (odds ratio = 0·79, 95% confidence interval 0·74-0·84) and basal ganglia location (odds ratio = 0·47, 95% confidence interval 0·26-0·83), but also with dysnatremia (odds ratio = 1·91, 95% confidence interval 1·08-3·40) and comorbidities such as upper gastrointestinal hemorrhage (odds ratio = 2·28, 95% confidence interval 1·33-3·91), pneumonia (odds ratio = 3·50, 95% confidence interval 2·17-5·63), urinary incontinence (odds ratio = 2·22, 95% confidence interval 1·40-3·51), and renal dysfunction (odds ratio = 2·28, 95% confidence interval 1·42-3·65).

CONCLUSION

Glasgow Coma Scale score and hematoma locations were independently associated with severity on admission and in-hospital mortality after primary intracerebral hemorrhage. The study also highlights the deleterious effect of comorbidities on in-hospital mortality following primary intracerebral hemorrhage in China.
