Effects of laser ingaalp for caesarean incision healing in patients with gestational diabetes

Abstract

PURPOSE: To evaluate the effects of LASER InGaAlP (660nm) treatment regarding wound healing in patients with gestational diabetes undergone caesarean section.
METHODS: It was performed at Clinic’s Hospital of the Federal University of Goiás, after Ethics Committee approval (CEP/HC.053/11). In the period between November (2011) and May (2015) 90 patients divided into 3 groups were assessed: Group A: LASER (3 Joules/cm2), Group B: LASER (6 Joules/cm2) and Group C (Control). Caesarean incision was photographed in the periods: T1 (1st), T2 (2nd), T3 (3rd), T4 (15th) and T5 (30th). Photos were used in order to calculate mean area and standard deviation. The area of the photographs was analyzed and calculated in pixels with specific software (Software Image J), measuring, thus, the wound contraction in percentage (%). The calculation was performed by the caesarean scar area reduction and the increase of incision contraction percentage (recovery) throughout the periods for each group studied, according to Kruskal Wallis Test.
RESULTS: The Groups treated with laser (A and B) presented higher edge contraction, being 89% the scar reduction of Group A (p<0.001) and 81% of Group B (p<0.05), when compared to control group (73%). However, Group A demonstrated higher wounded area reduction when compared to group B.
CONCLUSION: LASER therapy dosages of 3 and 6 joules presented higher percentage of surgical wound contraction (caesarean), when compared to the untreated group (control). Nevertheless, 3 J/cm2 dosage caused higher wound contraction (%) resulting in better caesarean incision esthetic aspect throughout 30 days of treatment.
