Brief summary
Meropenem is a powerful antibiotic used in intensive care for people who have very serious
infections. Meropenem is rapidly removed from the blood by the kidneys and it is very
expensive. In very ill patients in intensive care, it is uncertain how best to give this
antibiotic. Studies have suggested that a smaller dose given over a longer period of time,
results in blood levels of meropenem that are just as good as when a higher dose is given
over a shorter period of time. This direct comparison has not been tested in intensive care
patients. It is important to know this because if giving a lesser amount more slowly is just
as good, then doctors will choose to give meropenem this way. To establish whether this is
the case, the investigators plan to conduct an initial (pilot) study in ten intensive care
patients at Austin hospital.

Adult (age 18 years or older) patients in intensive care who have a serious infection being
treated with the antibiotic, meropenem for three days or more will be able to participate in
this study. The decision to start meropenem will be made by the intensive care doctors and
they will give it in the usual way for 24 hours.

The investigators will then in a random way (like tossing of a coin), give the participant
meropenem either in the usual way (1 gram infused over 30 minutes) or give them a smaller
amount, but over a longer period of time (500 milligrams infused over 3 hours). This will be
done for 24 hours. They will then receive meropenem in the alternative way for another 24
hours. After this time the intensive care doctors will decide how meropenem will continue to
be given.

Blood levels of meropenem will be measured to see if they are the same when meropenem is
given in each of the two different ways. During each different way of giving meropenem, 7
blood samples will need to be taken. Ten mls (or one spoonful) of blood will be required for
each measurement. Blood levels will be taken through monitoring lines, which will be already

Other information will also be collected about the participant during this study. This will
include their age, gender, height, weight, information about what other medical conditions
they have and measurements of how well their kidneys are functioning.
