Abstract

Background: Most surgical wounds seen in clinical practice in the Buea Health District, Cameroon are infected prior to arrival or while they are in the hospital. Sometimes the infection necessitates a combination of local wound site measures and systemic antibiotherapy to properly manage the patient.
Objective: To identify the current antibiotic susceptibility profile of the common germs that cause surgical wound infections in the Buea Health District of Cameroon.
Methods: A total of 2120 specimens comprising swabs from burns, ulcers, open or post-operative wounds were collected from hospitalized patients attending health institutions in Buea. The samples were collected from different anatomic sites of the patients. Cultures were effected from the specimens and bacteria isolated from infected wounds using standard microbiological techniques. Antibiotic susceptibility of the different isolates was determined.
Results: Majority (79.8%) of the wounds were infected with pathogenic bacteria. The germs globally showed multi resistant patterns to commonly used antibiotics in the study area, especially to co-trimoxazol, doxycycline, chloramphemicol, ampicilline and aztreonam. However appreciable sensitivity was noted to ofloxacillin, perflacin, and ceftriazone.
Conclusion: This study has revealed ofloxacin as the only antibiotic to which all the isolated bacteria from infected wounds were sensitive in the study area.

Abstract

Background: Wound infection causes great distress in terms of associated mortality and morbidity, increased length of hospital stay, profound discomfort and significant increased in healthcare cost. Infection in a wound delays healing and may cause wound break down, herniation of the wound and complete wound dehiscence.Therefore the knowledge of the causative agents of wound infection will be helpful in the control of wound infection and selection of empiric antimicrobial therapy as an
infection control measure.

Methods:A total of 207 wound specimens collected from patients attending the University of Benin Teaching Hospital were used for this study. All specimens were collected using sterile swabs sticks. Specimens were processed using standard microbiological methods.

Results:A total of 278 bacterial isolates were obtained from 207 wound specimens processed in this study. Positive growth were observed in 185 (89.4%) of the wound cultures and no bacterial isolates were obtained in 22 (21.1%) of the cultured materials. Staphylococcus aureus(26.9%) was the most predominant isolate followed by Klebsiellapneumoniae (17.6%), Pseudomonas aeruginosa (16.9%) and Escherichia coli(12.6%). All isolates were resistant to ampicillin, amoxyillin-clavulanate and tetracycline but show variable susceptibility to other antibacterial used. Majority of the
isolates produced beta lactamase.

Conclusion: A high proportion of the wounds were infected.The variety of microorganisms observed in this study support the need to obtain culture specimen from infected wounds for microbiological evaluation and antibiotic susceptibility determination, so that adapted chemotherapy can be prescribed.

Aerobic bacterial isolates from infected wounds

A Critical Review on HIV/AIDS and Wound Care

Abstract

Wound infections in AIDS patients increase discomfort, prolong hospital stay, render an additional burden upon an already debilitated patient and weaken the immune system further. Treatment must relate to the aetiology of the wound and take into account the patients underlying health problems. The treatment of wounds in HIV-AIDS patients is not different from the standard treatment. There are wound -related criteria for selecting the appropriate types of dressing. The best dressing for postoperative wound healing by secondary intention is unknown. Continuing wound evaluation and the appraisal of what dressing is useful for the type of wound and stage of healing is the basis of optimum wound care Optimum wound care, emotional support; health education will enhance both the emotional and physical wellbeing of the HIV-AIDS patient.
