Effectiveness in the Prevention of Superficial Infection of Polluted and Dirty Wounds with "Gasmanvac Drainaje", in the General Surgery Service of Iess Riobamba Hospital since August 2009-July 2013

Objective: To identify the effectiveness of the management of contaminated and dirty wounds with aspiration tubular drainage (GASMANVAC DRAINAJE) in subcutaneous cellular tissue in the General Surgery Service IESS Riobamba Hospital. Location: IESS Riobamba General Hospital. Design: Prospective, Transversal, Descriptive and Quasi-Experimental Study. Statistical analysis: Measures of central tendency. Patients and methods: A total of 675 postsurgical patients were analyzed in the IESS Riobamba Hospital between August 2009 and July 2013, who presented injuries classified as contaminated and dirty in which GASMANVAC DRAINAJE was used. The variables analyzed were age, gender, mass index surgery, surgery, aspiration tubular drainage, surgical wound infection and length of hospital stay. Results: Of the 675 patients, 4% presented superficial infection of the surgical wound, while 96% did not, considering it a favorable evolution for the majority of patients. Conclusions: The use of “GASMANVAC DRAINAJE” has demonstrated the reduction of surgical wound infection in the postoperative patient. If we compare the present study with the literature, which indicates that the infection in the case of contaminated wound is 15-30% and in the dirty one>30%, we can conclude that our investigation showed that this type of drainage is effective in the prevention of superficial infection of surgical wound presenting 4% of infection (1.6% contaminated wound and 2.4% dirty wound).
