Background: The aim of this research was to evaluate the feasibility and efficacy of absorbable bandage wrapping in the treatment of cases of severe liver trauma.
Methods: Electric firecrackers were detonated in 16 miniature swine to produce a severe blast liver injury. After fluid resuscitation, the animals were randomly divided into two groups (n = 8 each) and were either treated with absorbable bandage wrapping of the injured lobe of liver (Group B) or hepatic lobectomy (Group H). Time to hemostasis, blood loss during the treatment period, and other parameters were compared, including postoperative serum total bilirubin (TB), alanine aminotransferase (ALT), and aspartate aminotransferase (AST).
Results: Blood loss during the treatment period was significantly lower in Group B than that in Group H ((81.3 ± 26.0) ml vs. (130.8 ± 29.5) ml, P = 0.0031). Serum AST and ALT were transiently increased post-surgically. These transient increases were significantly higher in Group B. No difference in time to hemostasis was noted ((8.70 ± 2.27) minutes vs. (10.28 ± 1.93) minutes, P = 0.1559) in Groups B and H, respectively. Two pigs were humanely euthanized 28 days post-surgically and the wrapped liver lobes appeared atrophies. Microscopically, there was evidence of emerging and mature fibrous tissue.
Conclusion: Absorbable bandage wrapping is both feasible and effective in the treatment of severe blast liver injury.

Superabsorbent wound dressings for the management of highly exuding wounds: a literature review.

Exudate management is essential for creating a moist wound environment that promotes optimal healing, especially in highly exuding wounds, where choosing an appropriate wound dressing to handle high volumes of exudate is a key part of the wound management strategy. Superabsorbent wound dressings (SWDs) have been designed to absorb and retain large amounts of exudate. Thus, they are advocated for management of wounds with moderate-to-high levels of exudate to reduce the risk of leakage and damage to the periwound skin.

Emergency bleeding presents significant challenges such as high blood flow and rapid hemorrhaging. However, many existing hemostatic bandages face limitations, including the uncontrolled release of hemostatic agents, insufficient mechanical strength, poor adhesion, and complex manufacturing processes. To address these limitations, we developed a multifunctional hydrogel bandage for emergency hemostasis using a one-pot synthesis method.

Introduction And Hypothesis: Autologous fascia lata has been increasingly utilised in pelvic floor reconstructive surgeries such as sacrocolpopexy and sacrohysteropexy. This case highlights sacrohysteropexy with autologous fascia lata as a promising option for women with advanced uterovaginal prolapse who wish to preserve their uterus and avoid synthetic mesh.
Methods: We report the case of a 65-year-old woman with stage 3 pelvic organ prolapse following one forceps and one spontaneous vaginal delivery.

Moisture induced by wound exudate is crucial throughout the wound repair process. The dressing directly affects the absorption, permeation, and evaporation of the wound exudate. However, most dressings in clinical often result in excessive dryness or moisture of wound due to their monotonous structure and function, leading to ineffective thermodynamic control of evaporation enthalpy.

We report a rare case of Saturday Night Retinopathy (SNR) following postoperative orbital compression bandaging, highlighting the value of multimodal imaging in diagnosis and management. A 24-year-old male underwent surgical repair of an inferior orbital wall fracture with an absorbable implant, followed by compression bandaging of the right eye for three days. Upon bandage removal, the patient experienced a significant drop in visual acuity (VA) from 20/20 to 20/200.
