Expectations
 Students are required to attend the lectures.
 Attendance is obligatory on practical sessions.
 To participate on the practice is your interest: practical
items you can learn only here. Without required skill you
will not be able to pass exam.
 You are allowed to work only in the group where you
have registered on the Neptun portal.
 Because of limited capacity of operating theatre,
absences can be replaced only after registration by
joining another group.
Expectations
 Practical sessions begin exactly on time.
 Do not be late because you will not be able to
accomplish your task.
 Please note that during each course proper nail hygiene
is necessary (fingertip-high nails).
In addition, the use of nail-polish, artificial nails, any
jewellery, including watches are prohibited.
Who does not respect our requirements will not
take part on the courses and considered absent
without credit.
Expectations
 Handle the surgical instruments properly.
 If an instrument is damaged, cracked or broken
during your practice you should sign a statement.
 You do not need to pay for any damaged instruments
except if your responsibility is clear.
Practical sessions

Practical session
laparoscopic basic skills
A series of 6 plastic rings are picked up in turn by a grasping forceps from a
pegboard on the surgeon's left, transferred in space to a grasper in the
right hand, then placed around a post on the corresponding right-sided
pegboard.
After all rings are transferred from the left to right, the process is reversed,
requiring transfer from the right to left hand.
Peg transfer

This task is designed to
develop depth perception
and

visual-spatial perception in
a monocular viewing
system and

coordinated use of both the
dominant and nondominant
hands.

After the successful final exam
students are allowed to participate in the
research program of the department
(Students’ Scientific Association (TDK)
and demonstrator students are also welcome!
Please, contact course director or your teacher!
Operating theater
in which students and other
spectators could watch
surgeons to perform surgery.
Today the term is used as
operating room, the room
that provides a sterile
environment within a
hospital where surgical
operations are carried out.

Patient care – Future
SRI International, Menlo Park, CA
January, 2007
Operating team
consists of the chief surgeon,
who directs the surgery;
one or more assistant
surgeons, who help the chief
surgeon;
the anesthesiologist, who
controls the supply of
anesthetic and monitors the
person closely;
the scrub nurse, who passes
instruments to the surgeon;
and
the circulating nurse, who
provides extra equipment to the
operating team.
Anesthesia
The monitoring equipment
and anesthesia used during
surgery are usually kept at
the head of the bed.
The anesthesiologist stands
here to monitor the patient's
condition during surgery.
Depending on the nature of
the surgery, various forms of
anesthesia or sedation are
administered.
Operating room
typically contains a monitor
that displays vital signs, an
instrument table, and an
operating lamp.
Anesthetic gases are piped
into the anesthetic machine. A
catheter attached to a suction
machine removes excess
blood and other fluids, which
can prevent surgeons from
seeing the tissues clearly.
Intravenous fluids, started
before the person enters the
operating room, are continued.
Operating room
All personnel wear
protective clothing called
scrubs. They also wear shoe
covers, masks, caps, eye
shields, and other coverings
to prevent the spread of
germs.
The surgical site is cleansed and surrounded by a sterile
drape.
Location of the
Operating Theatre Suites

Separated from the main flow of hospital traffic

Should be easily accessible from surgical wards
and emergency rooms.

Floor should be covered with antistatic material,

The walls should be painted
with impervious, antistatic paint.
(reduces the dust levels and
allows frequent cleaning)

The surfaces must
withstand frequent cleaning and
decontamination with disinfectant.

Temperature and Humidity

The temperature and the humidity (not less than 55%)
play a important role in maintaining staff and patient comfort.

They must be carefully regulated and monitored.

Ideally, the operating room should be 1ºC cooler than the
outer area.
(In low humidity there is a danger of the production of electrostatic sparks.)
(This aids in the outward movement of air: the warmer air in the outer area rises
and the cooler air from within the operating theatre moves to replace it.)
Laminar flow & ultraclean air
Laminar airflow is designed to move particle free air over the
aseptic operating field in one direction.
It can be designed to flow vertically
or horizontally and is usually
combined with high efficiency
particulate air (HEPA) filters.
HEPA filters remove
particles > 0.3 micron in
diameter with an
efficiency of 99.97%.
