RESUMO
Objective To study the function of hyperbaric oxygen in the wound healing of skin dermabrasion.Methods A total of 32 cases of facial scar underwent skin dermabrasion,in which 20 cases were caused by acne and 12 cases by external injury.16 cases were given hyperbaric oxygen treatment after skin dermabrasion randomly and lasted for 6 days,while the other 16 cases were given only routine dressing change which was same to the hyperbaric oxygen group.We observed the wound healing time and dress changing time under the condition of hyperbaric oxygen and no hyperbaric oxygen after skin dermabrasion.Results Sixteen cases received hyperbaric oxygen recovered with short healing time,average 11 days,while other 16 cases received no hyperbaric oxygen recovered with longer healing time,average 16 days,without wound infection.Significant statistical difference (P＜0.05) was found by SPSS 11.5 analysis.However,the average time of dress changing in hyperbaric oxygen group was 5 days,which was a little more than that of the group without hyperbaric oxygen treatment (average time of 4 days) although there was no significant statistical difference between the two groups.Conclusions The wound healing of skin dermabrasion can be improved by hyperbaric oxygen.
