Hyperbaric oxygen in diabetic gangrene treatment

We treated a group of 18 hospitalized adult diabetic patients (all with
retinopathy, 17 with symptomatic neuropathy, and 6 with macroangiopathy)
presenting with gangrenous lesions of the foot by a combined regime
consisting of strict metabolic control, daily debridement of necrotic
tissues, and daily hyperbaric oxygen (HBO) treatments given in a multiplace
oxygen chamber. Another group of 10 adult subjects with comparable foot
lesions (all with retinopathy, 9 with symptomatic neuropathy, and 4 with
macroangiopathy) was treated in exactly the same way except for HBO. In the
test treatment group, 16 patients were healed, and the remaining 2 showed
no improvement and later underwent amputation. The number of HBO treatments
required for healing was significantly related to the size of gangrenous
lesions. In the non-HBO-treated group, only 1 patient improved, 5 of 10
showed no change, and 4 of 10 worsened until leg amputation was
unavoidable. Comparison of the two groups by chi 2-test revealed a highly
significant difference (P = .001). In practical terms, HBO treatment
drastically reduced leg amputations in patients so treated in the last 3 yr
compared with earlier and current figures for patients not receiving HBO
treatment.
