“…1 The wound healing process can be categorized into three phases: tissue in°ammation, which starts upon injury and normally lasts between 3 and 4 days, followed by the proliferative stage that involves the development of new blood vessels, which may take up to weeks, and lastly the tissue remodeling phase that produces the scarring of tissue. 2 Previous literatures 3,4 have revealed that the microcirculation system of the wound and its surrounding tissues shows an acute hypoxic condition from the constriction and rechanneling of blood vessels away from this site during the onset of tissue injury to mitigate bleeding; the recovery of wound tissue oxygenation through angiogenesis following this step is essential for physiological healing. In chronic wounds, such as diabetic wounds, tissue oxygenation fails to be restored, thereby impairing the healing processes.…”

This paper investigates the appropriate range of values for the transcutaneous blood oxygen saturation (S t O 2 ) of granulating tissues and the surrounding tissue that can ensure timely wound recovery. This work has used a multispectral imaging system to collect wound images at wavelengths ranging between 520 nm and 600 nm with a resolution of 10 nm. As part of this research, a pilot study was conducted on three injured individuals with super¯cial wounds of di®erent wound ages at di®erent skin locations. The S t O 2 value predicted for the examined wounds using the Extended Modi¯ed Lambert-Beer model revealed a mean S t O 2 of 61 AE 10:3% compared to 41:6 AE 6:2% at the surrounding tissues, and 50:1 AE 1:53% for control sites. These preliminary results contribute to the existing knowledge on the possible range and variation of wound bed S t O 2 that are to be used as indicators of the functioning of the vasomotion system and wound health. This study has concluded that a high S t O 2 of approximately 60% and a large°uctuation in this value should precede a good progression in wound healing.

“…Consequently, scars in most Asian patients require longer maturing [2,3]. Generally, wounds that do not heal within 2-3 weeks are considered most at risk for excessive scar formation [1,[4][5][6]. Asians are more likely to develop hypertrophic scars compared with Caucasians, and Africans are more likely to develop hypertrophic scars than Asians [5,7].…”

“…Scars can be disfiguring and aesthetically unpleasant. The side effects of scarring may include severe itching, tenderness, pain, sleep disturbances, anxiety, depression, and disruption of daily activities [5]. Scarring is a natural part of the healing process after an injury.…”

“…In addition to cosmetic concerns, scars may cause pain, pruritus, contractures, and other functional impairments [4,5,10,[12][13][14][15][16][17][18]. Although hypertrophic scarring commonly occurs following burns, many aspects, such as its incidence and optimal treatment, remain unclear.…”

The aim of this study was to assess the thickness of the scars on the left arm of a female third-degree burn patient through ultrasonic examination in order to investigate the use of 25-mm Hg pressure garments, which are a key treatment for burns. The patient was injured with third-degree burns more than 10 years ago. Sixteen scars were examined. The resulting Pearson correlation of the forearm and upper arm was 0.138 (weak correlation; R 2 =0.0191). Therefore, in this case, all data points fell on a straight line with a positive (upward) slope. This result indicated different thicknesses for the upper arm and forearm third-degree burn scars; this result displays different thickness for the upper arms and forearm the third degree burn scars; the scars did not spread evenly due to the loading capacity of different parts of body instead of the pressure by pressure garment.This paper provides accurate information to manufacturers, therapists, and tailors regarding measurements for pressure garments. The results suggest that burn scars should be subject to appropriate pressure on the basis of medium scar height to avoid increasing scars and to stabilise burns, validating the hypothesis that 25 mmHg is not the optimal pressure for female patients with third-degree burns on the left arm and that the optimal pressure should be based on the patient's burns and wound area. To our knowledge, this is the first study to correlate the thickness of third-degree burns through ultrasound scan.
