Adaptación de un sistema de presión negativa con succión central de bajo costo para el tratamiento de heridas ginecoobstétricas infectadas. Un estudio de cohorte retrospectivo

Abstract

Background

The objective is to describe a technique for placing a negative pressure wound therapy system using central suction as a treatment for infected surgical wounds in low-resource settings.

Methods

A retrospective cohort study was conducted at the General Hospital of Zapopan from November 2021 to May 2023. We included patients from the Gynecology and Obstetrics Department with infected and dehiscence surgical wound who consented underwent placement of a central suction system. Surgical time, intraoperative bleeding, complications, morbidity, and mortality were analyzed. We evaluated the patients in the preoperative, immediate postoperative, and 3-month follow-up.

Results

Ten patients were included, comprising 8 post-cesarean section patients, one post-hysterectomy patient, and one patient with Fournier's gangrene. The mean age was 29.91 years (± 12.97), with 5 patients having comorbidities. All patients with infected surgical wounds had wound dehiscence. Variations in the results of wound secretion cultures were found with the following pathogens: Staphylococcus lugdunensis, Staphylococcus epidermidis, Streptococcus gallolyticus and Klebsiella oxytoca, indicating no particular etiological agent. Length of hospital stay depended on the case, wound extent and depth, and the number of required changes.

Conclusion

Our technique is a cost-effective alternative for managing surgical wounds with favorable outcomes, suitable for replication in low-resource hospitals. However, further studies with a larger number of patients are needed.
