Abstract
2. The problem of i creasing postoperative wound infection
in B.U.H. was studi d bacteriologicaily.
50 cases of post wounds were subjected to
bacteriological stu which were found infected
this gives 1 percentage of 64; which is a
high rate.
The predominant organism was found to be Pseudomonas
cepacia presenting of cases, Klebsiella ranked
second presenting cases, Pseudomonas aeruginosa
~
presenting 15.6%, udomonas matoph1lia presenting 903%,
Staphylococcus aereu 9.3%, Proteus 6.2%, and Staphylococcus
epidermides 6 2%.
50 of the attendi personnel were bacteriologically
examined, where ster Ie swabs were taken from their
noses and throats. n the operating room, the floor,
the walls, the opera ing table, the lighting syste:a,
other equipments (an sthetic apparatus and endotracheal
s bed blankets, and the contents of
tube:~), and tae air ondi tion were examined. The autoclave
and sterile instrume ts were examined to determine steriliaation
efficiency. T e air of the operating room was also
examined.
the dressing table we e examined.
Colonies were iden ified morphologically and by biochemical
reaction, ai 0ng at tracing the source of
infection. Klebsiella was found in the disinfectant
solution used to soak nail brushes. Pseudomonas cepacia,
and aeroginoaa were fund in the dettol solution used to
68
immerse dressing in truments in the wards. Pseudomonas
maltophilia was fou endotracheal tubes.
Coagulase +ve staph lococcus was found in the noses and
throats of personne •
These results po·nt to disinfectant solutions as the
major cause of seps·s. Nail brushes must not be preserved
in a disinfectant s lution; it must be boiled and used
must be autoclaved in a
seperate sterile pa k for each patient. The noses and
throats of the atte dant personnel is the source of
coagulase +ve stap lococcus, and this fact calls for
the rigid and prope use of masks.
The change of infecting organisms, where
staphylococcus regre sed, and gave way to Gram-negative
organisms conformed ith the international results.
The rate of infec ion in B.U.H. were compared with
the international at ndards in a trial to improve the
epidemiological, ative, and patient care.
