Intraoperative blood perfusion factors in free anterolateral thigh flap repair for diabetic foot ulcers: A retrospective analysis

Figure 1 Preoperative blood gas analysis comparison between groups. A: Blood acidity or alkalinity; B: Pulse oxygen partial pressure; C: Arterial blood partial pressure of carbon dioxide. pH: Blood acidity or alkalinity; PaO₂: Pulse oxygen partial pressure; PaCO₂: Arterial blood partial pressure of carbon dioxide; NS: No statistically significant difference.

Figure 2 Preoperative hepatic and renal function differences between groups. A: Total Bilirubin; B: Albumin; C: Creatinine. NS: No statistically significant difference.

Figure 3 Correlation analysis between various variables and intraoperative blood perfusion in free anterolateral thigh perforator flap repair for diabetic foot ulcers in patients with type 2 diabetes. PaO₂: Pulse oxygen partial pressure; PaCO₂: Arterial blood partial pressure of carbon dioxide; Hb: Hemoglobin; HbA1c: Glycated hemoglobin; DPN: Diabetic peripheral neuropathy; BMI: Body mass index.
