Autologous platelet rich plasma in the healing of wounds by elective surgery, myth or reality? Experimental prospective study.

Abstract

Platelet-rich plasma is a biological product defined as part of the plasmatic fraction of autologous blood with platelet concentration above the baseline, being considered as an endogenous therapeutic technology with the potential to stimulate and accelerate tissue healing. OBJECTIVE: To evaluate the use of autologous platelet-rich plasma in the healing of surgical wounds in patients undergoing elective conventional cholecystectomy at the National General Hospital "Dr. Angel Larralde. METHODS: Cohort, observational and analytical study, with an experimental, prospective design, longitudinal cut. Non-probabilistic, intentional sample, made up of patients adjusted to inclusion criteria. Data Collection Sheet designed with the Vancouver scales and the Objective Assessment of Patient and Observer. The results obtained were tabulated in a data matrix made with Microsoft®Excel and, later, presented by means of frequency distribution tables and graphs. For the analysis and interpretation of the results, the free license program SPSS 26® was used. The Chi Square statistic was used. RESULTS: Total of 26 patients: study group with 11 patients, control group with 15 patients. The p value was calculated for both scales, resulting in ? 0.05 in all observations. CONCLUSION: An evident satisfactory evolution was observed in the patients to whom the PRP was applied compared to the control group, so that it supports the premise that the PRP contributes to rapid healing, without complications and easy to obtain.
