Objective To explore the advantages of a body surface drainage bag system in dressing changes for chronic wounds with sinus tracts,aiming to provide a reference for the clinical treatment of similar wounds.Methods A total of 62 patients who had chronic wounds with sinus tracts and visited the Wound Center of Jinshan Hospital from September 2022 to December 2023 were selected by convenience sampling.They were randomly divided into the test group(n=31)and the control group(n=31).During debridement of each dressing change,the test group used the body surface drainage bag system,while the control group used a traditional 20 mL syringe connected to a suction tube for irrigation.The wound exudate weight,sinus tract depth,pain degree and heart rate were compared between the two groups at initial assessment,Week 4 and Week 8 of enrollment,respectively.Results At initial assessment,there was no statistically significant difference in wound exudate weight,sinus tract depth,pain degree or heart rate between the two groups(P>0.05).At Weeks 4 and 8,the test group showed significantly lower wound exudate weight and significantly shallower sinus tracts than the control group;at Week 8,the test group showed significantly lower pain degree than the control group(P<0.05 for all).The wound exudate weight,sinus tract depth and pain degree decreased over time in both groups.During wound dressing changes at Weeks 4 and 8,the heart rate was statistically lower than at initial assessment(P<0.05 for both).Conclusion During debridement of each dressing change for chronic wounds with sinus tracts,the body surface drainage bag system more effectively controls wound exudate,promotes granulation tissue growth,and reduces patient pain.
