Safety and Tolerance of Intraoperative Enteral Nutrition Support in Pediatric Burn Patients

Metabolic and Hormonal Changes in Pediatric Burn Patients: Mechanisms, Evidence, and Care Strategies

BACKGROUND

Burn injuries constitute a significant global health challenge, especially in pediatric populations, where they are a leading cause of morbidity and mortality. Pediatric burns require particular attention due to their unique pathophysiology, long-term consequences on growth and development, and psychological impacts.

METHODS

We propose a comprehensive review of recent advancements in understanding the key aspects of hormonal and metabolic changes in burned children, aiming to guide therapeutic interventions, improve outcomes, and reduce the global burden of these injuries.

RESULTS

Effective management of the physiological stress response in pediatric burn patients necessitates a multidisciplinary approach integrating medical, nutritional, and rehabilitative strategies. Timely nutritional support and individualized plans preserve muscle mass, promote wound healing, and reduce complications and organ dysfunction risk. Advances in pharmacological interventions, such as beta-blockers, anabolic agents, and hormonal treatment, offer promising pathways to improve recovery and mitigate long-term complications. Early mobilization and physiotherapy are essential for preventing complications of prolonged immobility, including muscle wasting, joint contractures, and functional decline; their effectiveness is closely tied to advancements in minimally invasive procedures, regenerative medicine, and reconstructive techniques, particularly for pediatric patients.

CONCLUSIONS

While current strategies have significantly improved survival and outcomes for pediatric burn patients, ongoing research is critical to refine these new care strategies.

Safety and benefits of intraoperative enteral nutrition in critically ill pediatric burn patients: A systematic review and pooled analysis

Burn injuries significantly increase a patient's metabolic demand. Adequate nutrition is essential as an adjunct to recovery and reducing morbidity and mortality. In contrast to adults, this is especially important for pediatric patients who have limited reserves and are in a period of growth. Burn patients often require multiple anesthetic procedures that are accompanied by standard perioperative fasting periods that result in substantial nutritional interruptions. Continuous intraoperative feeding has been proposed as a solution, but there is no current consensus on its role and safety, particularly in the pediatric population. Thus, the goal of this study was to examine the safety and benefits of intraoperative nutrition in critically-ill pediatric burn injured patients. A systematic review of MEDLINE, PubMed, Scopus, and Web of Science was conducted using the following terms: feeding or enteral or nutrition or fasting and adolescent or youth or pediatric or child or teen and burn or thermal injury or fire. The primary outcome was incidence of aspiration. Secondary outcomes included patient nutritional status (caloric deficit and weight), wound healing, days spent in the intensive care unit, ventilator days, pneumonia, number of surgeries, length of hospital stay, and mortality. Pooled analyses of binary outcomes were computed. Four studies consisting of 496 patients, met inclusion criteria. All studies were level IV evidence, but had high methodological quality. The median burn total body surface area (TBSA) was 43.8% (IQR 33.4-58.8%), with a median of 30% of patients having an inhalational injury. Patients underwent a median of 4.2 surgeries (IQR 1.8-7.4). Intraoperative feeding was conducted through nasoduodenal tubes. There were no aspiration events. Pooled analysis demonstrated that there were no differences in rates of aspiration, pneumonia, or wound infection (p>0.05) between patients who were intraoperatively fed and those who were not. Those fed intraoperatively had significantly more surgeries, ventilator days, longer hospital stays, but lower mortality (p<0.05). There was large heterogeneity in nutritional assessment methods. Intraoperatively fed patients had an average gain of 144.4 kcal/kg,1.7 days of exclusive enteral nutrition (vs. loss of -119.1 kcal/kg and -1.4 days), and a cumulative positive caloric balance of +2673kcal ±2147 (vs. loss of -7899kcal ±3123) compared to those with interrupted feeding. Continuous intraoperative duodenal feeding during burn surgery appears to be safe in the pediatric burn population, with no reported episodes of aspiration. Uninterrupted feeding was also associated with weight maintenance and reduced caloric deficit. It may also have a survival benefit, as continuously fed patients needed more surgeries and intensive/hospital care, but had decreased mortality.

The Pediatric Burn: Current Trends and Future Directions

Management of the pediatric burn patient presents a variety of clinical challenges for the pediatric anesthesiologist. Despite the high incidence of burn injuries, standard management strategies are far from universal. The complex physiologic changes presented by burn injuries present airway management and resuscitation challenges and mandate careful consideration of adequate nutritional support. Long hospital stays with frequent operations and dressing changes necessitate creative approaches to anxiolysis and pain control. Underutilized modalities warranting further research include regional anesthesia and nonpharmacologic approaches, such as virtual reality. Further research and collaboration between burn centers are needed to standardize care for this population.

Pediatric burn resuscitation, management, and recovery for the pediatric anesthesiologist

PURPOSE OF REVIEW

The purpose of this article is to summarize literature in pediatric burn resuscitation and management that is relevant to the pediatric anesthesiologist. The scope of the literature is expanding as long-term survival in even the most critically ill, burn-injured children has increased.

RECENT FINDINGS

Longstanding variations in the care of burn-injured children exist despite decades of experience in burn care management. There seems to be a discomfort outside major burn centers in the triage, evaluation, and assessment of burned children. This is evidenced by the prevalence of 'unnecessary intubations', continued overestimation of total body surface area injured, and subsequent fluid administration disproportionate to injury leading to over-resuscitation. Techniques, such as virtual reality and regional anesthesia are increasingly available and serve adjuncts to pharmacologic therapies for anxiolysis and analgesia. Such techniques reduce opioid utilization while maintaining patient comfort and satisfaction particularly during wound dressing changes. Questions about transfusion threshold and ratio of blood products remain topics of ongoing research.

SUMMARY

Literature review continues to reveal underpowered or retrospective analyses of these very important questions. Public health burden caused by burns warrants rigorous, prospective studies to take the best care of these patients and portend the best long-term outcomes. Collaboration amongst pediatric anesthesiologists who care for these children is necessary to develop and execute powered studies to answer important questions.

Evaluating the Safety and Efficacy of Intraoperative Enteral Nutrition in Critically Ill Burn Patients: A Systematic Review and Meta-analysis

Major burn injuries incite a hypermetabolic response, and the initiation of early enteral nutrition is the standard of care in patients with large burns and contributes to improved outcomes. Perioperative fasting is a common cause of caloric deficits in burn patients and can be obviated with intraoperative enteral nutrition. However, the risks and benefits of this practice are unknown, and there is a concern for aspiration. We conducted a systematic review and meta-analysis to evaluate the safety and efficacy of intraoperative enteral nutrition. We performed a systematic literature search using PubMed, Scopus, and OvidSP MEDLINE databases. We identified studies that evaluated the effects of intraoperative enteral nutrition in adult burn patients compared to those undergoing routine perioperative fasting. We performed a meta-analysis on the incidence of mortality, pneumonia, wound infections, and aspiration in burn patients receiving intraoperative enteral nutrition. We identified seven articles for qualitative review and four for quantitative review (N = 83 patients). There were no statistically significant increases in the risk of mortality (odds ratio [OR] = 1.28, 95% confidence interval [CI]: 0.49, 3.31), wound infections (OR = 0.71, 95% CI: 0.16, 3.24), pneumonia (OR = 2.1, 95% CI: 0.7, 6.1), and aspiration (OR = 1.14, 95% CI: 0.07, 18.75) in patients receiving intraoperative enteral nutrition. Within individual studies, intraoperative enteral nutrition patients received significantly more calories than standard fasting patients. Intraoperative enteral nutrition may increase nutritional intake in burn patients without an increase in complications; however, this is based on limited studies. Randomized controlled trials are needed before recommendations on intraoperative enteral nutrition practice can be made.
