| Summary: |
Purpose: 1) To
evaluate the microbacterial flora of the conjunctival
sac and the sensitivity of the isolated microorganisms
to 0.3% gentamicin solution and 5.0% PVP-Jodi solution,
which is used to disinfect conjunctival sac. 2) To
evaluate the role of the adhesive foil in prevention of
the infection of the operative field.
Material and methods: 170 patients with senile
cataract were examined. Before admission to
Ophthalmology Department each patient received 0.3%
gentamicin solution three times a day. All patients had
their conjunctival sac disinfected with the use of 5%
PVP-Jodi before surgery. Patients were divided into two
groups. In the first group (120 patients), first samples
were taken on admission to the Ophthalmology Department.
Next in the day of the procedure, in the operation room
– first before and second after disinfection of
conjunctival sac. Adhesive foil was not used in this
group. In the second group (50 patients), we used
adhesive foil before surgery and samples were taken
before and after disinfection of conjunctival sac.
Results: On admission, positive cultures were
obtained in 40.0% cases. Most of the bacterial flora
were Gram-positive bacteria. The number of the positive
cultures before disinfection with 5.0% PVP-Jodi solution
diminished to 5.8%, compared with positive results
obtained on admission to the Ophthalmology Department.
Secondary infection of the conjunctival sac has been
revealed in 10% after disinfection with the use of the
5.0% PVP Jodi. It was due to bacterial flora coming from
the skin and limbs of the lids (in the group without
adhesive foil), whereas positive samples were obtained
in 2.0% in the group where adhesive foil was used.
Conclusions: 1) Gentamicin significantly reduces
the amount of bacterial flora in conjunctival sac in
patients before cataract surgery. 2) Adhesive foil is
efficient to protect operative field from infection. |
