CLINICAL STUDY OF POSTOPERATIVE WOUND INFECTION.

Background and Objective: Aim of this study was to 1. Study most common organisms encountered and their sensitivity and resistance to antibiotics in postoperative wound infection. 2. Study relation of emergency and elective surgery to postoperative wound infection. 3. Study efficacy of different modes of preoperative preparation on postoperative wound infection. 4. Study distribution of postoperative wound infection among different surgeries based on bacterial contamination such as clean, clean-contaminated, contaminated and dirty. Methods: 210 cases of postoperative wound infection were analyzed. Appropriate history and examination was done. Culture and sensitivity reports were reviewed. Results: Most common organism encountered is Pseudomonas (34.3%) most sensitive antibiotic is amikacin (80%) and most resistant antibiotics are Colistin (72.9%). Postoperative wound infection was commonly encountered in emergency cases (62.9%) and clean contaminated type of cases (32.9%). Postoperative infection is most commonly found in patients prepared, by shaving (76%), in > 24 hours before surgery (64.0%) and patients not taken preoperative bath (77.3%). Interpretation and Conclusion: Most common organism in post operative wound infection is Pseudomonas Most sensitive antibiotic is Amikacin and most resistant Colistin antibiotics are Postoperative wound infection is more in emergency case, clean contaminated type of cases and patients prepared, by shaving, in > 24 hours before surgery and who have not taken bath.
