Amnios con cobertura antibiótica: eficacia en pacientes sometidas a conización

Objective: To compare the evolution of healing in patients in whom amnion with antibiotic coverage was applied, with another group in which it was not applied, after cervical conization performed in cervical pathology consultations of the San Cristobal Central Hospital, between February and May 2023. Methods: Experimental, randomized, longitudinal comparison. It included 66 patients, randomly divided into two groups. Group 1: in which amnion was applied (n = 36/54.5 %); Group 2: no treatment (n = 30/45.5%). The researcher prepared the amnions of placentas obtained by cesarean section or vaginal delivery, in the operating room. Informed consent was obtained from both donors and recipients. Results: On day 14, none of the patients in the group 1 had epithelialization. In the group 2, one patient (2.7%) had 50% epithelialization and 35 (94.6%) had reached 100% (p < 0.001). Epithelialization was total in 13.3% of the first group and 94.6% of the second group (Odds Ratio of 227 (95% CI: 24.0 to 2157.0; p < 0.001). There were no cases of cervical infection. Five patients (16.7%) in the group 1 and one in the group 2 (2.8%) had ectopias (p = 0.051). There was no association between complete or partial epithelialization and clinical characteristics (p ˂ 0.05). Conclusion: Amnion with antibiotic coverage is associated with better healing outcomes in conized patients. Its effectiveness as a medical therapy was proven when placed on the surgical wound.
