Abstract
Objective
To evaluate therapeutic efficacy of teprenone-enriched oral rehydration solution (TORS) relative to World Health Organization’s recommended Oral Rehydration Solution (WHO-ORS) and identify the optimal concentration of TORS for early burn shock intervention.
Methods
A total of 350 male Wistar rats (200–220 g) were randomly divided into seven groups (n = 50/group): Sham (no burn and no treatment) group, Burn (no treatment) group, WHO-ORS group, and four concentrations of TORS (TRS1–TRS4). All groups, except Sham group, were subjected to 50 % total body surface area (TBSA) third-degree scald burns. Resuscitation protocols commenced immediately post-burn and continued every 2 h for 8 h, delivering TORS at 2 mL/kg/%TBSA (modified Brooke formula). Survival rates were measured at 72 h post-burn. High-resolution laser Doppler was used for gastric blood flow measurement; gastrointestinal mucosal damage was assessed via optical and transmission electron microscopy; blood teprenone levels were determined using reverse-phase high-performance liquid chromatography. Lactate, hematocrit, hemoglobin, malondialdehyde, superoxide dismutase, and interleukin-33 levels were analyzed.
Results
TORS administration resulted in higher 72- h survival rates in both Burn and WHO-ORS controls (P < 0.01 for TRS2 vs Burn), while exhibiting dose-dependent serum teprenone absorption. All TORS groups exhibited improved gastric blood flow, reduced gastric mucosal damage, and better performance in other measured parameters than the WHO-ORS group and Burn group. The TRS2 concentration was closest to the Sham group in most of the studied parameters.
Conclusion
The newly formulated TORS proved to be effectively emptied and absorbed by the gastrointestinal tract. This study establishes TORS as a viable oral resuscitation strategy, with TRS2 demonstrating optimal efficacy in improving tissue perfusion and survival outcomes over WHO-ORS, thereby offering a promising approach for early burn shock management. Further investigations are required to elucidate its underlying mechanisms.
期刊介绍:
Burns aims to foster the exchange of information among all engaged in preventing and treating the effects of burns. The journal focuses on clinical, scientific and social aspects of these injuries and covers the prevention of the injury, the epidemiology of such injuries and all aspects of treatment including development of new techniques and technologies and verification of existing ones. Regular features include clinical and scientific papers, state of the art reviews and descriptions of burn-care in practice.
Topics covered by Burns include: the effects of smoke on man and animals, their tissues and cells; the responses to and treatment of patients and animals with chemical injuries to the skin; the biological and clinical effects of cold injuries; surgical techniques which are, or may be relevant to the treatment of burned patients during the acute or reconstructive phase following injury; well controlled laboratory studies of the effectiveness of anti-microbial agents on infection and new materials on scarring and healing; inflammatory responses to injury, effectiveness of related agents and other compounds used to modify the physiological and cellular responses to the injury; experimental studies of burns and the outcome of burn wound healing; regenerative medicine concerning the skin.
