Therapeutic Outcome of Burn Patients Treated With Hyperbaric Oxygen

Amongst various interventions for burns and inhalation injuries, hyperbaric oxygen therapy (HBOT) has recently been widely integrated as an adjunctive management of care due to its therapeutic properties in reducing tissue hypoxia, pathological inflammation, and augmenting neovascularization. However, the limitation of human clinical trials and data undermines its efficacy to be implemented as an adjunctive therapeutic modality in burns. The purpose of the literature review is to determine the efficacy of HBOT as an adjunct to standard management in burns. A review of the literature was done by searching PubMed, Cochrane, Medline, EMBASE, and Google Scholar for papers addressing the comparison of therapeutic outcomes between HBOT and non-HBOT in burns. Current research findings are conflicting, and the use of HBOT as an adjunct in burns management is still controversial. Therefore there is still a need for more data and research on the therapeutic benefits of HBOT in burn management.

Incidence and risk factors for deep vein thrombosis among pediatric burn patients

BACKGROUND

Patients with major burns covering a large total body surface area (%TBSA) fulfill all the criteria of Virchow's triad, as a sequela of their injury. This places these patients at increased risk for developing deep vein thrombosis (DVT). However, data regarding the incidence of DVT in burn patients are minimal, especially in the pediatric age group. Therefore, the aim of this study is to determine the incidence of DVT in pediatric burn patients, identify possible risk factors for developing DVT, and explore the need for prophylactic treatment.

METHODS

A retrospective chart review of 95 patients admitted to our Burn Unit was conducted. We included all pediatric patients with second- and third-degree burns admitted to the unit. Exclusion criteria were adult patients, those with first-degree burns and admitted to the unit for <72h, patients discharged against medical advice, those admitted for elective reconstructive surgery, secondary admissions for non-healing/infected burns, and patients with trauma-induced skin loss. A data collection sheet was utilized.

RESULTS

The total incidence of thrombosis in our population was 4.2% (DVT, 3.1%; arterial thrombosis, 1.1%). Factors significantly associated with DVT included length of hospitalization (p=0.012), central venous catheter placement (p=0.013), and %TBSA (p=0.004). Unlike adult patients, weight for age (percentile) and body mass index were not significant risk factors for DVT in our patients.

CONCLUSION

Burns are a major risk factor for DVT, especially when covering large surface areas (≥40% TBSA) and combined with other factors (i.e., prolonged hospitalization and central lines). Thus, investigations for DVT and prophylactic anticoagulation should be considered for pediatric burn patients with these risk factors, even if they are asymptomatic.
