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.

IDEAL Phase 2a Results: Posterior Rectus Sheath Flap for Hiatal Augmentation in Complex Paraesophageal Hernias.

OBJECTIVE: To report the developmental phase results of posterior rectus sheath hiatal flap augmentation (PoRSHA), a promising surgical innovation for large and recurrent paraesophageal hernias. BACKGROUND: Durable hernia repair for large paraesophageal hernias continues to be a surgical challenge. PoRSHA addresses the challenges of current and historical approaches to complex paraesophageal hernias and demonstrates significant promise as a successful alternative approach. METHODS: Using the IDEAL framework, we outline the technical modifications made over the first 27 consecutive cases using PoRSHA. Outcomes measured included hernia recurrence on routine imaging at 6 months and 2 years, development of a postoperative abdominal wall eventration and incidence of solid food dysphagia. RESULTS: Twenty-seven patients at our single institution with type III (n=12), type IV (n=7), or recurrent (n=8) paraesophageal hernias underwent PoRSHA. Surgery was safely and successfully carried out in all cases. Stability of the technique was reached after 16 cases, resulting in 4 main repair types. At an average follow-up of 11 months, we observed no radiologic recurrences, no abdominal eventrations or hernias at the donor site, and 1 patient with occasional solid food dysphagia that resolved with dilation. CONCLUSIONS: PoRSHA can not only be safely added to conventional hiatal hernia repair with appropriate training but also demonstrates excellent short-term outcomes. While the long-term durability with 5-year follow-up is still needed, here we provide cautious optimism that PoRSHA may represent a novel solution to the long-standing high recurrence rates observed with current complex PEH repair.

Free Tissue Transfer in Sickle Cell Disease: A Case Report and Systematic Review.

Hemoglobinopathies such as sickle cell disease (SCD) are traditionally considered a relative contraindication to free tissue transfer, due to concerns that erythrocyte sickling will increase the risk of microvascular thrombosis and flap failure. This article describes a case report with the successful use of free tissue transfer in a patient with SCD and provides a systematic literature review on free tissue transfer in SCD. A retrospective chart review was performed of a patient with SCD who underwent free tissue transfer at the authors' institution. A systematic literature review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was performed using the keywords "free tissue transfer," "free flap," or "microsurgery" and "sickle cell" on PubMed, Ovid/Medline, and Scopus. A 29-year-old male with delayed presentation of an electrical burn to the face and scalp underwent wound closure with a free anterolateral thigh flap. Key management principles included red blood cell transfusion to keep hemoglobin S under 30% and hemoglobin greater than 10 g/dL, maintenance of hydration, normothermia, adequate analgesia, and postoperative anticoagulation. Systematic literature review identified 7 articles describing 13 cases of free tissue transfer in 10 patients with SCD, with combined complete free flap success in 10 of the 13 flaps. Free tissue transfer can be successfully performed in patients with SCD. However, evidence on the optimal management of this unique patient population in the perioperative period after free tissue transfer is limited to case reports in the literature.

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.

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.

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.

Transgender gender-affirming surgery consultation among patients seeking care in the Midwestern United States.

Gender-affirming surgery (GAS) is among the most rapidly growing and expanding subfields in plastic surgery due to increased awareness, decreased stigma, rising demand, and improved access for transgender and gender non-conforming individuals (TGNC). In order to address potential barriers and facilitators in GAS education and training, there is a need to explore the experiences of TGNC individuals. The purpose of this study was to qualitatively explore the factors that influence TGNC patient experiences in surgical consultation for GAS. Targeted recruitment was used to recruit and enroll participants who identified as TGNC and who had undergone consultation with a surgeon to discuss GAS. Semi-structured interviews were used to explore patient experiences with GAS. Recorded audio from these interviews was later transcribed verbatim. Open coding of these transcripts was then performed independently by 3 individual members of the research team using the consensual qualitative coding methods. Fifteen interviews were conducted (transmale, n = 7; transfemale, n = 4; gender non-conforming/non-binary, n = 4). Participants frequently expressed worry and frustration over insurance coverage and exorbitant out-of-pocket expense, whether actual or perceived. Logistical barriers were the most frequently cited category of barriers. The majority of participants made at least 1 reference to relying on others during the process of insurance pre-authorization. The majority of participants described their interactions with surgeons as positive, indicating that they felt comfortable during consultation and that their surgeons ensured their understanding. Our findings provide important insight into this often stressful and challenging process. Ensuring a welcoming, safe, and gender-affirming environment and experience for these individuals is essential. These findings may help to guide future education for medical students, trainees, clinic staff, and surgeons, as well as to direct changes necessary to improve the patient experience in clinics and hospitals for TGNC individuals undergoing consultation for GAS.

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.

Four-Quadrant Approach Squared: Ethical Analysis of Living Donation in Vascularized Composite Allotransplantation.

SUMMARY: Vascularized composite allotransplantation has become a widely accepted method for reconstruction or restoration of body parts, and the various ethical dilemmas that accompany vascularized composite allotransplantation have been widely discussed. As advancements in immunosuppression and tolerance continue to be made, the concept of living donor vascularized composite allotransplantation will likely become a popular option of the "reconstructive elevator." In this article, the authors discuss the various ethical implications of living donor vascularized composite allotransplantation.

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.

Autologous Posterior Rectus Sheath as a Vascularized Onlay Flap: a Novel Approach to Hiatal Hernia Repair.

INTRODUCTION: Complex and recurrent paraesophageal hernia repairs are a challenge for surgeons due to their high recurrence rates despite the use of various prosthetic and suturing techniques. METHODS: Here we describe the use of vascularized fascia harvested from the posterior rectus sheath with peritoneum during robotic hiatal hernia repair in two patients with large complex diaphragmatic defects. RESULTS: Successful harvesting and onlay of the right posterior rectus sheath based on a falciform vascular pedicle was achieved robotically by rotating and securing the flap to the diaphragmatic hiatus as an onlay flap following cruroplasty of the hiatal defect. CONCLUSIONS: In patients with difficult to repair large paraesophageal hernias, we demonstrate a promising new technique to restore the dynamic hiatal complex with the tensile strength of autologous vascularized fascia and peritoneum.

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.

Making Microwave Oven Doors Child Resistant to Protect Young Children From Severe Scalds.

Most severe child scalds in the United States involve food and beverages. The wide variety of burn mechanisms, however, makes prevention challenging. Over the past 15 years, we have worked toward protecting young children from 1 specific mechanism: children opening microwave oven doors themselves and spilling the heated contents, resulting in often severe scalds. In our published research, we documented the frequency and severity of these cases and the vulnerability of young toddlers to be burned in this way. We have presented our findings and ideas for prevention at multiple national meetings and enlisted college engineering students to design microwave doors that would thwart a young child from opening them. In 2017, we became active members of a national task group convened by Underwriters Laboratories to address this issue, and two authors became voting members on the Underwriters Laboratories Standards Technical Panel for microwave ovens. We worked with microwave manufacturers and others for >1 year to address concerns of the industry, including those related to potential impacts on older adults. This effort resulted in the task group proposing a change in the standard, requiring "two distinct actions" to open the door of a microwave oven. On September 17, 2018, the panel voted to pass the measure, which will require child-resistant doors for all new microwave ovens in 2023. This report highlights how research can inform and support child injury prevention advocacy. Children will now be protected from this type of scald as microwaves with child-resistant doors replace current models.

Ultradelayed Arterial Thrombosis: Critical Flap Ischemia After Phalloplasty.

BACKGROUND AND OBJECTIVES: Delayed arterial thrombus causing loss of a cutaneous free flap at or beyond 6 months is a rare phenomenon. The purpose of this report is to describe 2 cases of arterial compromise requiring medical and surgical intervention at or beyond 6 months after radial forearm free flap (RFFF) phalloplasty and to define the phenomenon of ultradelayed arterial thrombosis. METHODS: Patient 1 is a 44-year-old transmale who presented with pulselessness, pallor, and hypersensitivity of his neophallus 10 years status post-RFFF phalloplasty using a saphenous vein interposition graft (SVIG) between the superficial femoral artery (SFA) and radial artery (RA). Patient 2 is a 35-year-old transmale who presented with similar complaints 6 months status post-RFFF phalloplasty with the same vascular connections as above. RESULTS: Patient 1 was found to have an arterial thrombus distal to the SFA-SVIG anastomosis requiring catheter-directed thrombolysis with tissue plasminogen activator, resulting in partial loss limited to the distal three fourths of the shaft. Patient 2 was also found to have an arterial thrombus distal to the SFA-SVIG anastomosis requiring catheter-directed thrombolysis with tissue plasminogen activator and common femoral artery CFA-RA bypass, resulting in partial loss limited to the neoglans. CONCLUSIONS: Ultradelayed arterial thrombosis is a rare phenomenon requiring urgent intervention. The exact causes of this phenomenon, whether mechanical or physiological or both, have yet to be fully elucidated but it is hypothesized that the original anastomosis may continue to serve as the critical blood supply to its flap as far as 10 years after surgery.

Microsurgical vascular bypass in the setting of pediatric limb length discrepancy.

Management of pediatric iatrogenic arterial occlusions can be challenging clinically, leading to chronic complications such as claudication and limb length discrepancy. We report the case of a 6-month-old female patient who had experienced iatrogenic right external iliac and common femoral arterial occlusion. At the age of 8 years, she had developed claudication and a limb length discrepancy of 3.2 cm. She underwent common iliac artery to superficial femoral artery and profunda artery bypass via a branched autologous reverse great saphenous vein using microsurgical techniques for the distal anastomoses. In the present report, we have focused on the musculoskeletal improvements, benefits of microsurgery in pediatric vessels, and maximization of epiphyseal perfusion.

Postoperative extracorporeal membrane oxygenation can successfully support patients following upper airway reconstruction.

BACKGROUND: Patients requiring intensive upper airway reconstruction are anatomically restricted in terms of the respiratory support they can receive. While intraoperative extracorporeal membrane oxygenation (ECMO) has been effectively utilized, little has been shown regarding the utility of ECMO for long-term support in these patients. METHODS: We demonstrate how a patient with tongue and hypopharyngeal squamous cell carcinoma that necessitated upper airway reconstruction was supported with veno-venous (VV) ECMO due to postoperative respiratory failure and an inability to maintain a stable airway. RESULTS: By initiating VV ECMO, we were able to decrease positive pressure ventilation and FiO2 , thereby minimizing ventilator-associated trauma and irritation to facilitate wound healing. Over time, ventilatory support was increased in parallel with decreasing ECMO support, allowing discharge to rehabilitation after 74 days of ECMO. CONCLUSION: ECMO can effectively support patients with ongoing respiratory requirements following upper airway reconstruction when standard ventilatory techniques are inadequate or not feasible.

Urban Frostbite: Strategies for Limb Salvage.

Under ideal circumstances, severely frostbitten extremities are rapidly rewarmed and treated with thrombolytic therapy within 6 to 24 hours. In an "inner city," urban environment, most patients who suffer frostbite injuries present in a delayed fashion, sustain repeated injuries further complicated by psychological issues or intoxication, and are rarely ideal candidates for thrombolytic therapy within the prescribed timeframe. We describe our experience with the treatment of urban frostbite injuries. A retrospective review of patients with cold injuries sustained between November 2013 and March 2014 treated at a verified burn center in an urban setting was performed. Fifty-three patients were treated (42 males, 11 females). Average patient age was 41.8 years (range 2-84 years). No patients met criteria for thrombolytic therapy due to multiple freeze-thaw cycles or presentation greater than 24 hours after rewarming. Deep frostbite was seen in 10 patients. Of these patients, nine underwent debridement, resulting in partial limb amputations at levels guided by Tri-phasic technetium (Tc-99m) bone scans. Wound closure and limb-length salvage was then achieved by: free flap coverage (n = 2), local flaps (n = 8), split-thickness skin grafting (n = 22), and secondary intention healing (n = 6). While tissue plasminogen activator has been successful in reducing the need for digital amputation following frostbite injuries, in our experience, this treatment modality is not applicable to the urban patient population who often present late and after cycles of reinjury. Therefore, our approach focused on salvaging limb length with durable coverage, as the injuries were unable to be reversed.

Chimeric vs composite flaps for mandible reconstruction.

BACKGROUND: Composite mandibular reconstruction requires multiple tissue components inset in different planes. Intrinsic chimeric flap design provides this, and may be best suited for these reconstructions. METHODS: A retrospective review of mandible reconstructions with composite, intrinsic chimeric, or 2 free flaps was performed. Patient and flap characteristics and complications were analyzed. RESULTS: Seventy-five patients were reviewed. Defects reconstructed with intrinsic chimeric flaps had significantly more soft tissue needs than composite reconstructions. However, intrinsic chimeric bony defects were less complex. Despite significantly longer operative times for intrinsic chimeric flaps, there were no differences in complications or hospital stays. Intrinsic chimeric reconstruction resulted in significantly lower complication rates requiring an additional flap. This benefit was pronounced in through-and-through defects. CONCLUSION: Intrinsic chimeric flaps are a better option than composite flaps for reconstruction of mandibular defects with large soft tissue needs with no increased complication risk despite longer operative time.
