The effect of high fat dietary modification and nutritional status on the outcome of critically ill ventilated children: single-center study.

ABSTRACT:

Background

Ventilator dependency constitutes a major problem in the intensive care setting. Malnutrition is considered a major determinant of extubation failure, however, attention has been attracted to modulating carbon dioxide production through decreasing carbohydrate loading and increasing the percent of fat in enteral feeds. The detected interrelation between substrate oxidation and ventilation outcome became the base of several research to determine the appropriate composition of the nonprotein calories of diet in ventilated patients.

Purpose

We aimed to assess the effect of high-fat dietary modification and nutritional status on ventilatory and final outcomes of pediatric intensive care.

Methods

Fifty-one ventilated children (1 month to 12 years of age) with pulmonary disease who could be enterally fed, in the Cairo University Pediatric intensive care unit, were divided into 2 groups: group A included 25 patients who received isocaloric high-fat, low-carbohydrate diet; group B included 26 patients who received standard isocaloric diet. Comprehensive nutritional assessment was done for all patients.

Results

Group A had a significant reduction in carbon dioxide tension, but no similar reduction in the duration or level of ventilatory support. Assisted minute ventilation was predicted by weight-for-age and caloric intake rather than the type of diet. Poor nutritional status was associated with higher mortality and lower extubation rates. Mild hypertriglyceridemia and some gastrointestinal intolerance were significant in group A, with no impact on the adequacy of energy or protein delivery.

Conclusion

The high-fat enteral feeding protocol may contribute to reducing carbon dioxide tension, with mild hypertriglyceridemia and negligible gastrointestinal intolerance as potential adverse effects. Optimization of nutritional status rather than dietary modification may improve ventilatory and survival outcomes in critically ill-ventilated children.

Project description:BackgroundThe incidence of malnutrition in children, who were admitted to the pediatric intensive care unit (PICU), has kept high level over the past 30 years. In addition, nutrition status of critically ill children deteriorates further during the changing of their conditions and may have a negative effect on patients' outcomes. This study aimed to determine the nutritional status of critically ill children and to survey current nutrition practices and support in PICU.MethodsIn this prospective observational study, 360 critically ill children stayed in the PICU not less than 3 days from Feb. to Nov. in 2017 were enrolled. Each patient underwent nutrition assessment. Nutritional status was determined using Z-scores of length/height-for-age (HAZ), weight-for-age (WAZ), weight-for-height (WHZ), body mass index-for-age (BAZ), based on the World Health Organization child growth standards. We also observed the patients' intake of calories and protein during the first 10 days after admission.ResultsThree hundred and sixty were enrolled in the study. One hundred and eighty-six patients (51.67%) were malnourished at PICU admission, above 50% and 56.45% (105/186) of malnourished patients had severe malnutrition. Except fasting in case of clinical instability in 5.3% (19/360), nutrition was provided in the form of oral feeding in 26.6% (96/360), enteral nutrition (EN) in 56.1% (202/360), parenteral nutrition (PN) in 6.4% (23/360) and mixed support (EN + PN) in 5.6% (20/360). Totally 384 times interruption of feeding happened in the process of EN, and 1.9 times feeding interruption happened to each patient. Twenty-seven point two percent of these patients had more than three times feeding interruption. The severe malnutrition group had significantly greater length of ICU stay and higher mechanical ventilation support rate (P=0.007, P=0.029). Total 44 (44/360, 12.22%) patients died in the study, and the malnutrition was not statistically different between survivor group and death group (P=0.379). More than 85% of the patients had lower daily nutritional intake compared with prescribed goals. Sixty-eight point three percent of the patients received the required calories during EN with median time of 2 [2-4] days. Only 32.7% of patients underwent EN received estimated protein requirements.ConclusionsThese results showed that malnutrition was common among children admitted to PICU. Furthermore, nutrition delivery was generally inadequate in critically ill children, and nutritional status was getting worsening during PICU.

Project description:IntroductionSmoking is highly addictive, and nicotine abstinence is associated with withdrawal syndrome in hospitalized patients. In this study, we aimed to evaluate the impact of sudden nicotine abstinence on the development of agitation and delirium, and on morbidities and outcomes in critically ill patients who required respiratory support, either noninvasive ventilation or intubation, and mechanical ventilation.MethodsWe conducted a prospective, observational study in two intensive care units (ICUs). The 144 consecutive patients admitted to ICUs and requiring mechanical ventilation for >48 hours were included. Smoking status was assessed at ICU admission by using the Fagerström Test of Nicotine Dependence (FTND). Agitation, with the Sedation-Agitation Scale (SAS), and delirium, with the Intensive Care Delirium Screening Checklist (ICDSC), were tested twice daily during the ICU stay. Agitation and delirium were defined by SAS >4 and ICDSC >4, respectively. Nosocomial complications and outcomes were evaluated.ResultsSmokers (n = 44) were younger and more frequently male and were more likely to have a history of alcoholism and to have septic shock as the reason for ICU admission than were nonsmokers. The incidence of agitation, but not delirium, increased significantly in the smoker group (64% versus 32%; P = 0.0005). Nicotine abstinence was associated with higher incidences of self-removal of tubes and catheters, and with more interventions, including the need for supplemental sedatives, analgesics, neuroleptics, and physical restraints. Sedation-free days, ventilator-free days, length of stay, and mortality in ICUs did not differ between groups. Multivariate analysis identified active smoking (OR, 3.13; 95% CI, 1.45-6.74; P = 0.003) as an independent risk factor for agitation. Based on a subgroup of 56 patients, analysis of 28 pairs of patients (smokers and nonsmokers in a 1:1 ratio) matched for age, gender, and alcoholism status found similar results regarding the role of nicotine withdrawal in increasing the risk of agitation during an ICU stay.ConclusionsNicotine withdrawal was associated with agitation and higher morbidities in critically ill patients. These results suggest the need to look specifically at those patients with tobacco dependency by using the FTND in ICU settings. Identifying patients at risk of behavioral disorders may lead to earlier interventions in routine clinical practice.

Project description:ImportanceAmong critically ill adults, randomized trials have not found oxygenation targets to affect outcomes overall. Whether the effects of oxygenation targets differ based on an individual's characteristics is unknown.ObjectiveTo determine whether an individual's characteristics modify the effect of lower vs higher peripheral oxygenation-saturation (Spo2) targets on mortality.Design, setting, and participantsA machine learning model to predict the effect of treatment with a lower vs higher Spo2 target on mortality for individual patients was derived in the Pragmatic Investigation of Optimal Oxygen Targets (PILOT) trial and externally validated in the Intensive Care Unit Randomized Trial Comparing Two Approaches to Oxygen Therapy (ICU-ROX) trial. Critically ill adults received invasive mechanical ventilation in an intensive care unit (ICU) in the United States between July 2018 and August 2021 for PILOT (n = 1682) and in 21 ICUs in Australia and New Zealand between September 2015 and May 2018 for ICU-ROX (n = 965).ExposuresRandomization to a lower vs higher Spo2 target group.Main outcome and measure28-Day mortality.ResultsIn the ICU-ROX validation cohort, the predicted effect of treatment with a lower vs higher Spo2 target for individual patients ranged from a 27.2% absolute reduction to a 34.4% absolute increase in 28-day mortality. For example, patients predicted to benefit from a lower Spo2 target had a higher prevalence of acute brain injury, whereas patients predicted to benefit from a higher Spo2 target had a higher prevalence of sepsis and abnormally elevated vital signs. Patients predicted to benefit from a lower Spo2 target experienced lower mortality when randomized to the lower Spo2 group, whereas patients predicted to benefit from a higher Spo2 target experienced lower mortality when randomized to the higher Spo2 group (likelihood ratio test for effect modification P = .02). The use of a Spo2 target predicted to be best for each patient, instead of the randomized Spo2 target, would have reduced the absolute overall mortality by 6.4% (95% CI, 1.9%-10.9%).Conclusion and relevanceOxygenation targets that are individualized using machine learning analyses of randomized trials may reduce mortality for critically ill adults. A prospective trial evaluating the use of individualized oxygenation targets is needed.
