SURGICAL SITE INFECTIONS IN CLEAN AND CLEAN CONTAMINATED WOUNDS A PROSPECTIVE STUDY

Abstract

Background – clean wounds include those in which no infection is present; only skin microora potentially contaminate the wound. Clean contaminated wounds Include those in which a hollow viscus such as respiratory, alimentary or genitourinary tracts with indigenous bacterial ora is opened under controlled circumstances without signicant spillage of contents. This study hopes to compare surgical site infection in two types of wounds as well as most common organism causing surgical site infection. After explaining the patients regarding the study Methodologydesign, patients giving informed consent were enrolled for the study. All the patients were assessed pre-operatively by taking relevant detailed clinical history, examination and all investigations and work-up required prior to surgery. At the end of surgery, standard closure protocol was followed. Cleaning the open wound with normal saline followed by skin suturing, followed by application of spirit - normal saline - dry gauze; followed by occlusive type of dressing. Wound was opened for dressing on the 3rd post-operative day, unless there are local/systemic signs of inammation or soakage. Sterile cotton swabs will be obtained from the depth of wounds showing signs and symptoms of SSI and were sent for culture and sensitivity and antibiotics were started accordingly. Presence Results- of diabetes mellitus is a signicant risk factor for causing surgical site infection in clean contaminated wounds (p<0.05) whereas presence of diabetes mellitus is not a signicant risk factor for causing surgical site infection in clean wound (p>0.05). Presence of drain/implant is a signicant causative factor for both clean and clean contaminated wounds (p<0.05). Presence of hypertension is not a signicant causative factor for clean wound (p>0.05) as well as clean contaminated wound (p>0.05). According to this study the rate if surgical site infection in clean w Conclusion- ounds is 6.66% and in clean contaminated wounds is 12%.
