Health-related quality of life after burn injury due to bioethanol-fueled fireplaces

OBJECTIVE

Commercially available bioethanol-fueled fireplaces are a potential source of burns and are commonly used for home use. The present study aimed to evaluate the quality of life following burn injuries that were caused by bioethanol-related accidents.

METHODS

Burned patients who were admitted to our burn unit with burn injury due to bio-ethanol fueled fire places between January 2010 and December 2021 were contacted to ask for their willingness to participate in this study. They were asked to answer questions regarding the circumstances of the accident and three questionnaires to capture burn specific and general health related quality of life (Burn Specific Health Scale-Brief (BSHS-B), Short-Form Health Survey 36 (SF-36)) and general information about the accident. Patients were matched and compared to a group of patients suffering comparable burns from other burn mechanisms, which were also admitted to our burn unit at the same time.

RESULTS

Of 35 patients that met the inclusion criteria, 19 answered the questionnaire and were compared to 38 patients with other burn mechanisms. There were no statistical differences regarding age (bioethanol: 37.4 ± 14.7 years vs. control: 36.2 ± 14.3 years, p = 0.777), TBSA (9.9 ± 6.8% vs. 8.9 ± 10.4, p = 0.715), and sex (42.1% females vs. 36.8% females, p = 0.882). Most patients in the bioethanol-group reported that they did not follow the manual instructions (68.4%) and that the accident happened during the refilling process (52.6%). There was no significant difference in any subscale of the BSHS-B or the SF-36.

DISCUSSION

Burns related to bioethanol-fueled fireplaces are rare compared to other typical burn mechanisms. However, as they are used for personal pleasure and interior design, psychological impairment following burn may be even more critical. Detailed education on the use of these fireplaces needs to take place in order to reduce the risk of accidents.

Enzymatic debridement in scalds is not as effective as in flame burns regarding additional eschar excision: A retrospective matched-control study

OBJECTIVE

Enzymatic debridement of burn eschar became an accepted and widely used technique for burn wound treatment over the last years. However, this practice is not exempt from failure and recent experimental studies indicate that it may not be as efficient in scalds as in flame burns.

METHODS

Patients that were admitted to the burn intensive care unit between June 2017 and February 2021 and received enzymatic debridement within the first 72 h after scald and flame burn were included. Patients with scald burns were matched regarding age, sex and per cent total body surface area (%TBSA) burned in a 1:2 ratio with patients presenting with flame burns.

RESULTS

Eighteen patients with scald burns were matched with 36 with flame burns. After matching, both groups were similar in terms of age (flame burns 44.5 ± 21.1 years vs. scald 41.8 ± 22.6 years, p = 0.666), and %TBSA burned (11.0 ± 8.2% vs. 10.6 ± 9.6%, p = 0.851). Patients with scald burns significantly more often underwent further surgical eschar excision compared to controls (scald 16 (88.9%) vs. flame 19 (52.8%), p = 0.016). Length of stay per %TBSA was significantly longer in scald burns (scald 7.8 ± 9.2 days vs. flame 3.7 ± 3.8, p = 0.013).

CONCLUSION

This study indicates that enzymatic debridement may not be as effective in scalds as in flame burns. It was shown that patients with scalds and subsequent enzymatic debridement more frequently underwent additional surgical intervention and that the size of the transplanted area was larger compared to control. Moreover, those patients had a longer length of stay at the hospital per %TBSA burned.

Tranexamic acid reduced blood transfusions in acute burn surgery: A retrospective case-controlled trial

OBJECTIVE

Early excision and grafting of burn wounds are key for reducing prevalence of infection and sepsis. However, it is associated with massive blood loss and patients frequently require large numbers of blood transfusions. This study aimed to evaluate the effect of tranexamic acid (TXA) on blood transfusion requirements in acute burn surgery.

METHODS

Patients admitted to the burn intensive care unit between January 2018 and May 2021 and received TXA before first surgery for wound excision and grafting were matched in a 1:2 ratio to patients that did not receive TXA (confounders age,sex,total body surface area (TBSA) burned). Primary endpoint of the analysis was the total number of transfused units of red blood cells (RBC) intra- and postoperatively up to 48 h. Fresh frozen plasma (FFP) and platelets were evaluated. Endpoints were compared between groups using van Elteren tests adjusting for strata variable age, gender, TBSA.

RESULTS

Twenty-six TXA patients were matched with 52 control patients resulting in similar distributions of gender (77.9%(TXA)vs. 82.7%(control) males, p=0.542), age (51.7±21.3vs.48.3 ±17.4years,p = 0.459) and %TBSA burned (33.5%(IQR34)vs. 38.5% (IQR 30.5),p = 1.000). TXA group received significantly less RBC units intraoperatively (2.5(IQR 2.0)vs.4.0 units (IQR4.0), p = 0.038) and in total (4.0(IQR3.0)vs.6.0(IQR4.0),p = 0.017). TXA patients also received less blood products in general (RBC, FFP, platelets) in each period and in total. We found no significant difference in length of stay (24.0(IQR26.0)vs.33.0 days (IQR 0.5),p = 0.367) or mortality (15.4%vs.21.2%, p = 0.542).

DISCUSSION

This study shows that necessity for blood transfusions in acute burn surgery may be reduced significantly by administration of TXA perioperatively. Randomized-controlled trials are needed to prove these findings.
