<strong>Spiegelberg</strong>: Probe 2<br />
Directions for use. Read carefully!<br />
Method<br />
The air-pouch system consists of a<br />
hollow body connected to a pressure<br />
transducer by tubing. The pressure<br />
transducer, the electronic hardware,<br />
and the device for filling the air-pouch<br />
are integrated in the Brain-Pressure<br />
Monitor.<br />
For epidural pressure measurement the<br />
air- pouch is placed on the dura of the<br />
patient. The intracranial pressure is<br />
transmitted across the thin pouch wall<br />
to the air volume in the pouch and<br />
transformed into an electric signal by<br />
the pressure transducer.<br />
On the digital display the mean<br />
pressure is shown. At the monitor<br />
output both the mean pressure and<br />
the pulsatile signal are available.<br />
Once every hour the Brain-Pressure<br />
Monitor opens the pressure transducer<br />
to atmospheric pressure for zero<br />
adjustment. The air-pouch is then filled<br />
with the exact air volume required for<br />
accurate pressure transmission.<br />
Indication and Function<br />
Probe 2 is to be used postoperatively<br />
after large trepanation. If the air-tube<br />
is to be placed in a subgaleal tunnel a<br />
skin incision of about 1 cm in length is<br />
necessary. The probe head is then<br />
introduced in a distal to proximal<br />
direction. This is done fairly easily by<br />
forming a loop of the tubing and<br />
pushing the loop through the tunnel.<br />
The probe head is then pulled through<br />
the tunnel. Due to the risk of<br />
perforating the diaphragm the probe<br />
head should not be handed with a<br />
forceps or other sharp tool.<br />
In principle, after mobilisation of a<br />
sufficiently large area of the dura, the<br />
probe can be inserted between the<br />
dura and the cranial bone through a<br />
burr-hole. This application has a higher<br />
risk of epidural hematoma.<br />
Probe Check<br />
Connect probe to Brain-Pressure Monitor.<br />
Note that the tube end and the<br />
connector are non-sterile now. Switch<br />
on monitor and watch emptying and<br />
filling of air-pouch. The pressure<br />
reading must be around zero.<br />
Remaining checks with palpating<br />
finger (moist). Apply a slightly pulsating<br />
pressure on the air-pouch. Watch the<br />
undulating signal on the monitor.<br />
Possible sources of error are:<br />
Pressure artifacts caused by adherence<br />
of probe membrane. Resolve by<br />
manipulating membrane.<br />
Leaky probe, red warning indicator<br />
appears. Probe should be replaced.<br />
No pulsation on the monitor. Tubing<br />
kinked or clogged. 0297<br />
Placement of Probe 2<br />
The probe is placed under the bone<br />
flap such that the measuring<br />
diaphragm is in contact with the dura.<br />
A perforation of the diaphragm at the<br />
bone edge is to be avoided. The probe<br />
is to be placed away from possible<br />
sutures of the dura.<br />
Connect probe to Brain-Pressure Monitor,<br />
switch on monitor, read brain<br />
pressure. It is advised to check for<br />
pulsation on a patient monitor. The<br />
amplitude of the brain-pressure should<br />
be plausible in relation to the mean<br />
pressure. In healthy man the ICP-wave<br />
has an amplitude of 1 to 4 mmHg. With<br />
elevated ICP the amplitude rises to 10-<br />
20 mmHg and even more. If the<br />
measured ICP appears to be high with<br />
a low amplitude, the dura might not be<br />
stripped from the bone sufficiently. Also<br />
a kinked tubing or a tilted probe could<br />

mean ICP which is not accompanied by<br />
a rise of the amplitude can indicate an<br />
epidural hematoma. In that case<br />
remove the hematoma and read ICP<br />
anew.<br />
Direct air tube vertically out of wound,<br />
close with approximately four<br />
interrupted sutures. Affix suture flap,<br />
form loop.<br />

Removal of Probe 2<br />
Disconnect probe from the Brain-Pressure<br />
Monitor. After loosening of a possible<br />
suture at the skin incision Probe 2 is<br />
pulled out of the wound. Possibly<br />
secondary suture.<br />
Warning<br />
This probe is designed and is intended for<br />
single use for the measurement of ICP with<br />
the <strong>Spiegelberg</strong> Monitor HDM 13.x, HDM<br />
26.x, or HDM 29.x. Do not resterilize. Do<br />
not reuse. With reuse an infection risk<br />
exists. Do not fill with saline or other liquid<br />
media. Do not use if package is damaged.<br />
