249 diabetic patients with deep foot infection were retrospectively studied. Their clinical features and effective factors related to wound healing were analyzed.249 patients team (physician, surgeon and diabetes-specific nurse) were divided into 3 groups. Group A: patients healed without amputation (n = 107), group B: patients healed after amputation (n = 114), and group C: patients didn't heal after amputation. All patients' clinical features, lab examinations and foot wound features were compared.The group A patient were (59 +/- 12) years old, significantly younger than the group B (67 +/- 11, P0.01). Hypersensitive C reactive protein (hs-CRP, 18 +/- 5 mg/L) and plasma albumin (32 +/- 7 g/L) of group A were significantly higher than those of group B (13 +/- 5 mg/L and 29 +/- 5 g/L, respectively, P0.01). The duration of diabetes mellitus of group B (17 +/- 11) year was significantly longer than that of group A (10 +/- 6 year, P0.05). The possibility of probing bone, purulent secretion, necrosis, bone exposure, cacosmia, edema and critical limb ischemia of group B were more frequent (P0.01 or P0.05) compared to group A. The age of group B (67 +/- 11) are younger than that of group C (72 +/- 9, P0.05). In group B, temperature (38.1 +/- 1.1) degrees C, white blood cell (WBC) count (10 +/- 3) x 10(9)/L and hs-CRP (13 +/- 5) mg/L were higher than those of group C (37.4 +/- 0.8 degrees C, 8 +/- 2 x 10(9)/L and 7 +/- 6 mg/L, respectively, all P0.05). Critical limb ischemia of group B (37%) was more frequent than that of group A (7%, P0.05), but less frequent than that of group C (77%, P0.01). hs-CRP and plasma albumin were protective factors for wound healing. Age, the possibility of probing bone, purulent secretion, necrosis, bone exposure, cacosmia, edema and critical limb ischemia were risk factors for wound healing.diabetic patients with deep foot infection are difficult to be diagnosed in early stage since they often have no significant clinical syndrome such as fever, redness, swelling and pain, and their WBC count does not increase. Though multidisciplinary team manages these patients, more than half of them need amputation. Wound healing in the patients is related to multiple factors, including age, duration of diabetes mellitus, hs-CRP, plasma albumin, WBC count, level of limb ischemia and wound features. |
