Acute Burn Care.

LEARNING OBJECTIVES: After studying this article and viewing the videos, the participant should be able to: 1. Describe the current epidemiology of burn injuries. 2. Understand burn pathophysiology and perform a wound assessment. 3. Summarize the initial emergency management of a burn patient. 4. Calculate the anticipated fluid resuscitation requirements for a burn injury, and diagnose the complications of overresuscitation. 5. Describe the diagnosis and management of inhalation injury. 6. List the goals of wound care for superficial and deep burns, and describe the closed dressing technique. 7. Perform excision of a burn wound. 8. Compare various wound closure techniques using autografts and skin substitutes. SUMMARY: Plastic surgeons are essential members of the multidisciplinary burn team. Burn injuries remain common, and plastic surgeons have an opportunity to develop and innovate the field of acute burn care in light of workforce shortages. Burn pathophysiology is complex and dynamic, which informs the challenges encountered during the perioperative phase. Accurate burn wound assessment remains difficult, with implications for diagnosis and management. A systematic approach is required when stabilizing a major burn and/or inhalation injury with newly updated fluid resuscitation and triage guidelines. Wound care continues to evolve, with an emphasis on a closed dressing technique. For deeper burns, new surgical techniques are emerging for surgical débridement, along with improvements to traditional methods of tangential excision. Following excision, a number of established and novel techniques are available to close the wound with either autografts or skin substitutes.

Factors Predicting 90-Day Readmissions for US Older Adult Burn Patients From the 2016-2018 Nationwide Readmissions Database.

Older adults with burn injuries have a high risk of readmission after the initial burn admission. Frailty is associated with poor outcomes from the initial burn injury, however, it remains unknown if frailty impacts readmission in older adults after the initial index burn admission. Our study aims to examine patient, frailty, burn, surgical, and hospital factors that contribute to 90-day readmissions in older adults with an acute burn. Patients ≥ 50 years of age with an acute burn diagnosis in the Nationwide Readmissions Database (2016-2018) were included. Patients who died during index admissions were excluded from the readmission analysis. Patient, burn, hospital stay, and hospital characteristics were analyzed. Using variables significant from univariate logistic regression analysis, we performed a multivariable logistic regression analysis to identify factors associated with 90-day readmissions. A total of 41,500 weighted index burn admissions were included. The 90-day readmission rate was 25.6% (10,641/41,500). Almost all the readmissions were unplanned (96.5%). The most common primary readmission diagnoses based on Clinical Classifications Software Refined were burn injury and septicemia. Multivariable logistic regression analysis demonstrated an increased hospital frailty risk and lower-body-only burns were associated with an increased risk of readmission. Notably, surgical treatment of the burn injury during the index admission was associated with a decreased risk of readmission. This highlights the importance and challenges of surgical decision-making for older adults with high comorbidity burden. Future studies are needed to develop decision guides to help clinicians identify patients who would benefit from surgical treatment versus more conservative strategies in older adult patients with burns.

Running water while bathing is a risk factor for pediatric scald burns.

INTRODUCTION: Scalds are the most common mechanism of burn injury in pediatric populations and scald burns sustained during bathing present a unique opportunity for injury prevention. Evidence-based infant bathing educational resources recommend checking water temperature and having a caregiver present for the duration of the bath, but do not explicitly recommend avoiding running water or explain the associated risks. This study seeks to determine the incidence and role of running water in bathing scald burns at our institution. METHODS: This is a retrospective review of pediatric patients (<3 years) admitted to the University of Chicago Burn Center with scald injury from bathing between 2010 and 2020. Cases were reviewed to assess the following risk factors: whether there was running water, whether water temperature was checked before placing the child in water, and whether a caregiver was present for the entire bath. Injuries in which the manner of injury was abuse or indeterminate were excluded. RESULTS: The study cohort included 101 cases of scalds due to bathing, with a mean age of 13 months and mean burn size of 7% TBSA. Of these 101 cases, 96 (95%) involved running water. Thirty-seven cases (37%) had only one of the three risk factors and 95% of those 37 cases involved running water. Twenty-nine cases (29%) involved all three risk factors while only two cases (2%) involved none of the three risk factors. Sixty-one cases (60%), thirty-nine cases (39%), and one case (1%) occurred in a sink, bathtub, or infant tub, respectively. CONCLUSION: We found that the vast majority of bathing scald burns involved running water, identifying a specific bathing recommendation that should be added to existing guidelines to reduce the incidence of bathing scald burns.

Burn Prevention in Spanish: Assessment of Content Accuracy, Website Quality, and Readability of Online Sources.

Burn prevention information may be inadequate or inaccessible to communities with non-English language preference. Our objective was to systematically analyze the content accuracy, website quality, and readability of online Spanish information for burn prevention in the home and compare it to English websites. We collected the top ten burn prevention results from a search on Google, Bing, and Yahoo using a list of Spanish key terms. Using recommendations from national organizations and a burn care expert team, content accuracy was evaluated for each website. We assessed website quality following the "Health on the Net" Code of Conduct. Readability was scored by averaging five validated readability tests for the Spanish language. After using the same protocol, a comparison was made with English websites as a control. Once duplicates and non-relevant search results were removed, 23 Spanish websites were assessed. Out of 21 possible points for content accuracy, the top website scored 14 (67%) and the average score was 6.6 (31%). For website quality, the average score was 50%. The average grade level needed to read the websites was 8.6. Compared to English, Spanish websites were less accurate (31% vs 41%), harder to read (9.8 vs 7.8), but were of higher website quality (50% vs 43%). Online burn prevention information in Spanish is often inaccurate, incomplete, and inferior to available English language websites. We propose a call to action to increase the quality of online burn prevention material available in Spanish.

The Revised Baux Score as a Predictor of Burn Mortality: A Systematic Review and Meta-Analysis.

Mortality following a severe burn is influenced by both patient- and injury-factors, and a number of predictive models have been developed or applied. As there is no consensus on the optimal formula to use, we aimed to investigate the predictive value of the revised Baux score in comparison to other models when determining mortality risk in patients with burn injuries. A systematic review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. The review yielded 21 relevant studies. The Prediction model Risk Of Bias ASsessment Tool quality appraisal checklist was used with many studies classified as "high" quality. All studies assessed the utility of the revised Baux score in comparison to other scoring systems such as the original Baux, Belgian Outcome in Burn Injury, Abbreviated Burn Severity Index, Acute Physiology and Chronic Health Evaluation II, Sequential Organ Failure Assessment, Boston Group/Ryan scores, the Fatality by Longevity, APACHE II score, Measured Extent of burn, and Sex model, and the Prognostic Burn Index. There was a range of 48 to 15975 participants per study, with a mean age range of 16 to 52 years old. The area under the curve (AUC) values of the rBaux score ranged from 0.682 to 0.99, with a summary AUC of 0.93 for all included studies (CI 0.91-0.95). This summary value demonstrates that the rBaux equation is a reliable predictor for mortality risk in heterogeneous populations. However, this study also identified that the rBaux equation has a diminished ability to predict mortality risk when applied to patients at both extremes of age, highlighting an important area for future research. Overall, the rBaux equation offers a relatively easy means to quickly assess the mortality risk from burn injury in a broad range of patient populations.

Pediatric instant noodle burns: A ten-year single center retrospective study.

INTRODUCTION: Children are particularly vulnerable to scald injuries, and hot beverages/foods are often implicated in this subset of pediatric burns. Burns from instant noodles are common and thus an attractive target for burn prevention. The purpose of this study is to characterize the frequency, demographics, outcomes, and circumstances of pediatric instant noodle burns to guide future educational and prevention efforts. METHODS: This is a retrospective review of all pediatric patients (<18 years) admitted to the University of Chicago Burn Center with a diagnosis of scald injury between 2010 and 2020. Burns caused by instant noodles were identified and compared to all other scald burns over this period. RESULTS: Among 790 pediatric scald burns, 245 (31.0 %) were attributed to instant noodles. Compared to other scalds, patients with instant noodle burns were older (5.4 vs. 3.8 years, p < 0.001), equally likely to be male (51 % vs. 54 %, p = 0.488), and more likely to be Black/African American (90.6 % vs. 75.2 %, p < 0.001). Patients with instant noodle burns lived in zip codes with a lower average childhood opportunity index score (9.9 vs. 14.6, p < 0.001). In terms of circumstances, children with instant noodle burns were more likely to be unsupervised at the time of injury (37 % vs 21 %, p < 0.001). Instant noodle burns were smaller (3.6 % total body surface area (TBSA) vs. 5.8 % TBSA, p < 0.001) and less likely to require operative intervention (29 % vs. 41 %, p < 0.001). Instant noodle burns had a shorter length of stay (4.2 days vs. 6.4 days, p < 0.001), but similar adjusted length of stay (1.7 days/%TBSA vs. 1.5 days/%TBSA, p = 0.18) and experienced similar complication rates (10 % vs. 15 %, p = 0.06). CONCLUSION: Instant noodle burns comprised nearly one-third of all pediatric scald burn admissions at our institution, a higher proportion than previously reported. While less severe than other scald burns in this series, instant noodles injuries still demonstrated a need for hospitalization and operative intervention. Instant noodle burns disproportionately affected Black/African American patients, as well as from neighborhoods with lower socioeconomic status. These findings suggest that focused burn prevention efforts may be successful at reducing the incidence of these common, but serious injuries.

Staphylococcal Toxic Shock Syndrome in a Burned Child Treated with an Antimicrobial Foam Dressing: A Case Report.

Staphylococcal toxic shock syndrome (TSS) is a severe systemic disease characterized by fever, hypotension, desquamating rash, and multiorgan dysfunction. Attributed to bacterial exotoxins, TSS has been a known, though rare, complication in the field of pediatric burns for decades. The adoption of new antimicrobial burn dressings has allowed for the management of small to medium sized burns with minimal discomfort or inconvenience to the patient. In this report, we discuss a 3-year-old male with burns wounds dressed using a silver-impregnated foam who went on to develop TSS.

Topical Hemostatic Agents in Burn Surgery: A Systematic Review.

Acute burn surgery has long been associated with significant intra-operative bleeding. Several techniques were introduced to limit hemorrhage, including tourniquets, tumescent infiltration, and topical agents. To date, no study has comprehensively investigated the available data regarding topical hemostatic agents in burn surgery. A systematic review was performed by two independent reviewers using electronic databases (PubMed, Scopus, Web of Science) from first available to September 10, 2021. Articles were included if they were published in English and described or evaluated topical hemostatic agents used in burn excision and/or grafting. Data were extracted on the agent(s) used, their dosage, mode of delivery, hemostasis outcomes, and complications. The search identified 1982 nonduplicate citations, of which 134 underwent full-text review, and 49 met inclusion criteria. In total, 32 studies incorporated a vasoconstrictor agent, and 28 studies incorporated a procoagulant agent. Four studies incorporated other agents (hydrogen peroxide, tranexamic acid, collagen sheets, and TT-173). The most common vasoconstrictor used was epinephrine, with doses ranging from 1:1000 to 1:1,000,000. The most common procoagulant used was thrombin, with doses ranging from 10 to 1000 IU/ml. Among the comparative studies, outcomes of blood loss were not reported in a consistent manner, therefore meta-analysis could not be performed. The majority of studies (94%) were level of evidence III-V. Determining the optimal topical hemostatic agent is limited by low-quality data and challenges with consistent reporting of intra-operative blood loss. Given the routine use of topical hemostatic agents in burn surgery, high-quality research is essential to determine the optimal agent, dosage, and mode of delivery.

Comparing the Efficiency of Tumescent Infiltration Techniques in Burn Surgery.

Tangential excision and grafting of burn wounds result in significant intraoperative blood loss, and infiltration of a dilute epinephrine solution (tumescence) is routinely performed to reduce such bleeding. Tumescent infiltration has been described using both a manual technique (syringe) and a pump device. The purpose of this study is to compare the efficiency of these two methods in terms of time and economy of motion. Consecutive adult burn patients at a single center requiring excision and grafting were enrolled in the study and randomized into either the manual or pump technique. Excisions involving less than 2% TBSA were excluded, along with specific anatomic regions (eg, head and neck). Infiltration with epinephrine solution (1:500,000) was performed to the endpoint of tumescence by a single surgeon and filmed/coded for duration, number of maneuvers, and volume of tumescence injected. Fourteen patients were enrolled, and 16 cases were randomized to either manual (N = 8) or pump infiltration (N = 8). The pump method required less time (2.0 vs 1.1 cm2/s, P < .001) and fewer maneuvers (37.8 vs 1.1 cm2/move, P < .001) to reach the desired endpoint of tumescence. Use of the infiltration pump also resulted in a reduced volume of tumescent fluid required to reach this point of tumescence (1.7 vs 2.4 mL/cm2, P = .01). Compared to the manual technique, an infiltration pump was significantly more efficient in terms of both time and economy of motion. These reductions are potentially useful for improving operating room efficiency as well as minimizing operator fatigue.

Pneumomediastinum, Facial Nerve Injury, and Sialocele Secondary to a Firework Burn to the Cheek: A Case Report.

Fireworks injuries can result in devastating cutaneous burns and may be further complicated in the head and neck region by the presence of specialized deeper structures. In the United States, the head and neck remain the most commonly injured sites, with the majority of these injuries constituting burns. We present an adult patient who suffered an accidental right cheek burn injury and went on to experience a complex pattern of findings including pneumomediastinum, facial nerve palsy, and sialocele formation.

Prognostic Factors for In-Hospital Mortality of Geriatric Burns From the US National Inpatient Sample 2016 to 2018.

Older adults with an acute burn experience a high frequency of in-hospital mortality. However, traditional burn mortality prediction models are less accurate for older adults likely because they do not account for geriatric specific factors, such as frailty. This study aims to investigate the impact of frailty on in-hospital mortality in older adult burn patients. Patients ≥50 years of age with an acute burn diagnosis in the National Inpatient Sample (2016-2018) were included in the cohort. Three multivariable logistic regression models to predict in-hospital mortality were generated and compared. The models were 1) age and percent total body surface area, 2) age, percent total body surface area and the Elixhauser Comorbidity Index, and 3) age, percent total body surface area, and Hospital Frailty Risk Score. A total of 60,515 weighted discharges were included in the cohort. In-hospital mortality increased with age, as 3.3% of 50- to 64-year-olds, 5.3% of 65- to 74-year-olds, 6.6% of 75- to 84-year-olds, and 9.9% of ≥85-year-olds died during the acute burn admission (P < .001). The multivariable model that included Hospital Frailty Risk Score had a higher area under the receiver operating characteristics curve than the model with age and percent total body surface area (0.84 vs 0.79; P < .001) and the model with Elixhauser Comorbidity Index (0.84 vs 0.83; P = .013). Frailty improved prediction of in-hospital mortality for older adult acute burn patients and burn specialists should consider implementing a frailty instrument to evaluate older adults with an acute burn injury.

Burn Injuries Associated with At-Home Hair Braiding.

Hair braiding that incorporates synthetic extensions has increased in popularity across all age groups. As part of the styling process, the ends of the braid are commonly dipped in scalding water; an increasing number of patients have presented to our center after containers of recently boiled water are accidentally tipped over and spilled onto patients. A retrospective chart review was performed of all patients who sustained burn injuries related to at-home hair braiding presenting to an ABA-verified burn center between January 1, 2006 and July 31, 2020. A total of 41 patients presented over the study period, and the frequency of this type of burn increased over time, with 54% of injuries occurring in the past 3 years (2018-2020). The mean patient age was 7.5 years, and the majority of patients were under 18 years of age (97%), female (95%), and African-American (98%). Seventy-three percent of injuries occurred in the home and 88% involved another person in the hair braiding process. The mean TBSA burned was 5% (range 1-20%). The most commonly involved areas were the back (54%), thigh/leg (37%), and neck (24%). Ninety percent were partial-thickness injuries only, with 10% having some degree of full-thickness injury. Ninety percent of patients required inpatient admission, and 34% of patients required at least one operative procedure. Hair braiding, with the use of scalding water to seal and set the ends of braids, can lead to burn injuries that require hospitalization and the need for surgical intervention.

The quality of survey research in burn care: A systematic review.

INTRODUCTION: Burn care is a relatively small, mutidisciplinary field with variability in practices between centers. Given these factors, survey studies are frequently used to better understand practice variations, establish guidelines, and direct future research. If survey research is poorly designed or reported, it limits the ability to form meaningful conclusions. This study evaluates the quality of survey studies published in burn care and determines areas of improvement to increase generalizability. METHODS: A systematic review was performed by two independent reviewers. Three databases (PubMed, Scopus, Web of Science) were queried between January 1, 2000 and March 19, 2020. Studies were included if they surveyed any member of the multidisciplinary burn team on a topic related to burn care, and surveys of non-clinicians were excluded. Data related to survey content, methodology, and quality was extracted for analysis. RESULTS: Of 247 citations, 144 met inclusion criteria. The number of published surveys increased by an average of 23% annually over the study period (p < 0.001). Studies represented a breadth of countries, scopes, themes, and disciplines. Few studies reported using reminders or incentives. The majority did not report survey development steps or validity/reliability, and half did not include the questionnaire in the publication. The median (IQR) response rate of all studies was 54% (32-83). A subgroup analysis of surveys to North American burn directors (N = 28) had a response rate of 40% (26-50). CONCLUSION: Survey reporting in the burn care literature is generally inconsistent, limiting the ability to apply this research into practice.

Antishear Therapy for Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis: A Follow-up Study.

Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN) are life-threatening conditions best approached with multidisciplinary burn-equivalent care. There is a lack of consensus on wound management, in particular, whether to debride detached epidermis. Our center instituted "antishear" wound therapy 35 years ago, where detached skin is left in situ as a biologic dressing and a standardized protocol avoids shear forces to prevent further desquamation. Our center's initial results showed outcomes comparable to SCORTEN predictions, but advancements in burn critical care necessitate a reevaluation of the antishear approach. A retrospective chart review was conducted for all patients admitted between June 2004 and May 2020 with a dermatologist-confirmed diagnosis of SJS/TEN (N = 51). All patients were treated with burn-equivalent critical care and antishear wound therapy. Standardized mortality ratios were calculated using the established SCORTEN, and newly developed ABCD-10, prediction models. Mean SCORTEN, ABCD-10, and %TBSA were 2.6, 2.0, and 28%. Overall mortality was 22%; SCORTEN score (P < .001), ABCD-10 score (P < .01), %TBSA involved (P = .02), and development of multisystem organ failure (P < .001) correlated with increased mortality. Cohort-wide standardized mortality based on ABCD-10 was 1.18 (P = .79). Standardized mortality based on SCORTEN was 0.62 (P = .20) and 0.77 (P = .15) for patients with scores ≤3 and >3; across the cohort it was 0.71 (P = .11), representing a 29% mortality reduction. Incorporating the antishear approach as part of burn-equivalent care for SJS/TENs led to outcomes comparable to those predicted for surgical debridement via SCORTEN. However, the antishear approach has the advantage of avoiding painful dressing changes, sedation, and general anesthesia required for surgical debridement.

Hypoglycemic episodes predict length of stay in patients with acute burns.

Hypoglycemic episodes are associated with worse hospital outcomes. All adult patients admitted to our burn center from 2015 to 2019 were retrospectively reviewed. Patient demographics and burn characteristics were recorded. The primary outcome was mortality, and secondary outcomes were total length-of-stay and intensive care unit length-of-stay. All patients experiencing at least one hypoglycemic episode were compared to patients who did not experience hypoglycemia. There were 914 patients with acute burns admitted during the study period, 33 of which (4%) experienced hypoglycemic episodes. Of these, 17 patients (52%) experienced a single hypoglycemic episode, while the remainder experienced multiple hypoglycemic episodes. Patients with one or more hypoglycemic events were matched to non-hypoglycemic controls using propensity matching. Patients that experienced hypoglycemia had significantly less TBSA involvement (5% vs. 13%,median, p < 0.0002), higher prevalence of diabetes (48% vs. 18%, p < 0.0001), higher mortality (18% vs. 7%, p = 0.01), longer total length-of-stay (22 vs. 8 days, median, p < 0.0001), and longer ICU length-of-stay (12 vs. 0 days, median, p < 0.0001). A single hypoglycemic episode was associated with prolonged total (IRR = 1.91, p < 0.0001) and ICU length-of-stay (IRR = 3.86, p < 0.0001). Hypoglycemia was not associated with higher mortality in the survival analysis (p = 0.46).

Orbital Compartment Syndrome Following Major Burn Resuscitation: A Case Series and Survey of Practice Patterns.

Orbital compartment syndrome (OCS) is a rare but devastating complication of over-resuscitation in burn patients that may lead to permanent visual loss. The purpose of this study was to 1) present a series of burn patients with OCS and 2) survey practice patterns of monitoring intra-ocular pressure (IOP) during burn resuscitation. Cases of OCS at two American Burn Association (ABA)-verified burn centers were retrospectively reviewed. Patients were included if they 1) required lateral canthotomy/cantholysis for elevated IOPs or 2) developed blindness on admission unrelated to any other ocular pathology. Data were collected on demographics, burn characteristics, fluid administration, ophthalmologic findings, and complications. An eight-item electronic survey was distributed by email through the ABA to all physician members. Twelve patients with OCS were identified, with a mean age of 47.8 ± 12.4 years and TBSA of 63.7 ± 18.6%. Mean fluid resuscitation at 24 hours was 4.9 ± 1.6 ml/kg/%TBSA or 0.29 ± 0.06 liter/kg. Eight patients underwent canthotomy/cantholysis for OCS, whereas four were later found to have visual loss. A total of 83 (14%) ABA physicians responded to the survey. IOP was routinely measured by 23% of respondents during acute burn resuscitation. OCS appears to have developed despite a relatively low 24-hour ml/kg/% burn resuscitation volume, but with a relatively higher cumulative (liter/kg) fluid volume. Their survey found that monitoring of IOP during burn resuscitation is not routinely performed by the majority of providers. Taken together, the present study suggests clinical guidelines to recognize this complication of over-resuscitation.

The Homelessness Crisis and Burn Injuries: A Cohort Study.

The United States is facing a growing homelessness crisis. We characterize the demographics and outcomes of homeless patients who sustain burn injury and compare them to a cohort of domiciled patients. A retrospective cohort study was performed at the Los Angeles County + University of Southern California Regional Burn Center for consecutive acute burn admissions in adults from June 1, 2015, to December 31, 2018. Patients were categorized as either domiciled or homeless at the time of their injury. Prevalence rates were estimated using data from the regional homeless count. From 881 admissions, 751 (85%) had stable housing and 130 (15%) were homeless. The rate of burn injury requiring hospitalization for homeless adults was estimated at 88 per 100,000 persons. Homeless patients had a significantly larger median burn size (7 vs 5%, P < .05) and a greater rate of flame burns (68 vs 42%, P < .001). For the homeless, rates of assault and self-inflicted injury were 4- (18 vs 4%, P < .001) and 2-fold higher (9 vs 4%, P < .001), respectively. Homeless patients had higher rates of mental illness (32 vs 12%, P < .001) and substance abuse (88 vs 22%, P < .001), and were less likely to follow-up as outpatients (54 vs 87%, P < .001). There was no difference in mortality. Homeless patients had a longer median length of stay (LOS; 11 vs 7 days, P < .001) without significant differences in LOS per percentage TBSA. Homeless individuals should be considered a high-risk population for burn injury. This distinction serves as a call to action for the development of burn prevention strategies.

Stimulant Abuse in Burn Patients Is Associated With an Increased Use of Hospital Resources.

Stimulant (cocaine, methamphetamine, and amphetamine) abuse compromises the peripheral vasculature through endothelial injury. In combination with the physiologic derangements seen in burn injuries, patients abusing stimulants may have additional impairments in wound healing. A retrospective review from July 1, 2015 to July 1, 2018 was performed at an American Burn Association-verified burn center. Patients with positive urine toxicology results for stimulants (ST(+)), and those without (ST(-)), who sustained burn injuries were identified and matched by age and TBSA. The primary outcome was mortality, and secondary outcomes included total length of stay (LOS), and need-for-surgery (grafting). In total, 130 patients ST(+) and 133 ST(-) patients were identified. There were no significant differences in age (40.9 ± 13.5 vs 39.2 ± 23.7 years, P = 0.46), Inhalation Injury (12.3 vs 9.0%, P = 0.39), or nutritional status (prealbumin: 17.3 ± 6.1 vs 17.1 ± 12.7 mg/dl, P = 0.66; albumin: 3.5 ± 0.6 vs 3.6 ± 0.7 g/dl, P = 0.45). There were no differences in mortality (6.1 vs 4.5%, P = 0.55), intensive care unit LOS (9.3 ± 16.5 vs 10.2 ± 20.9 days, P = 0.81), wound infections (15.4 vs 23.9%, P = 0.07), or wound conversion (6.9 vs 3.0%, P = 0.14). ST(+) patients had a significantly longer LOS (15.0 ± 16.9 vs 10.7 ± 17.3 days, P = 0.04), greater tobacco use (56.9 vs 18.0%, P = 0.00001), and greater need for grafting (54.6 vs 33.1%, P = 0.0004). ST(+) patients require more hospital resources-surgical operations and hospital days-than ST(-) patients. The increased need for surgical intervention may partially explain the increase in hospital days, in addition to the observation that ST(+) patients had more complex disposition issues than ST(-) patients.

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.
