Abstract

Background: Since patients admitted to the intensive care unit have a compromised immune system and are more prone to infection than other patients, timely diagnosis and treatment of corneal ulcers among this group of patients can prevent vision loss. Therefore, it is necessary to treat eye infections and corneal ulcers promptly and economize prohibitive costs.

Objective: Appropriate treatment with the most effective antibiotic before the answer is available to prevent corneal ulcer complications and blindness.

Methods: This study was conducted from November 2019 to November 2020 and after approval by the ethics committee of Hamedan University of Medical Sciences with the code of ethics: IR.UMSHA.REC.1398.716. First, the corneal secretions of 121 patients admitted to the intensive care unit of Sina Hospital are prepared by an ophthalmologist (after anesthetizing the cornea with tetracaine drops and sterile swabs) and culture in four growth mediums (blood agar, chocolate agar, thioglycolate, and EMB). Microbial cultures are examined after 48 hours and a fungal culture is examined one week later. Disc diffusions are placed in positive microbial cultures. Antibiotic susceptibility or resistance of the antibiogram was recorded. Other demographic data, including patients' age and sex, are extracted from ICU files. Also, test results and patient identifications are recorded in a checklist designed for this purpose.

Results: Of all the antibiotics used against common bacteria, vancomycin (84%), colistin (80.43%), cefazolin (80%), and levofloxacin (60%) had the highest sensitivity and gentamicin (93.75%), ceftazidime (86.42%) Erythromycin (85%) had the highest resistance against isolated bacteria.

Conclusion: The data obtained from this study showed that the most common microorganisms in the age group under the age of 30 years were Acinetobacter Baumannii, in the group of 30-60 years old was Klebsiella pneumonia, and age group over 61 years old was Staphylococcus aureus, and the most sensitive antibiotics in the age group under 30 years were vancomycin and levofloxacin and the age group30-60 were colistin and vancomycin and in the age group over 61 years were vancomycin and cefazolin.
