Một số đặc điểm lâm sàng của vết thương chi dưới ở bệnh nhân đái tháo đường tại Trung tâm Liền vết thương Bệnh viện Bỏng Quốc gia Lê Hữu Trác

Abstract

Objective: To identify selected clinical characteristics of acute lower-extremity wounds in patients with diabetes mellitus type 2 and investigate risk factors associated with delayed wound healing. 
Subjects and Methods: A prospective descriptive longitudinal study was conducted in total of 82 patients aged ≥ 30 years with diabetes mellitus type 2 and acute lower-extremity wounds, referred from other healthcare facilities and admitted to the Wound Healing Center, Le Huu Trac National Burn Hospital, within 24 hours, were included in the study from June 2025 to November 2025. Factors associated with wound status were evaluated. 
Results: Among the study participants, 60.98% were over 50 years of age. Accidental injuries accounted for 51.22% of acute wounds. Hypertension was the most common comorbidity, occurring in 23.17% of patients. The duration of diabetes was less than 10 years in 67.07% of cases. The most common location of lower-extremity wounds was the foot and toes (58.54%). Moderate-depth wounds accounted for 76.83% of cases. An ankle-brachial index (ABI): 1-1,4 was observed in 73.17% of patients, while 6.1% required vascular intervention before continuing wound treatment. 
Conclusion: Acute lower-extremity wounds in patients with diabetes mellitus are mainly caused by accidents, with the foot being the most commonly affected site. Assessment of the ABI and thorough evaluation of lower-extremity arterial status, together with timely vascular intervention, may contribute to more effective wound management.
