Purpose: To study the effect of spine surgery on the intraocular
pressure (10P) and the end visual outcome at various situations.
Patients and methods: 45 patients, grade I & II American Society
Association (ASA) fitness were assigned to undergo spine surgery under
general anaesthesia. Patients were divided into three equal groups: group
I; performed spine surgery on prone position, group II; the same in
addition to pre-operative martnitol 0.5 gram/ icy, and group III: performed
the surgery on the lateral position.
10P was measured before pre-medication, after induction of
anaesthesia in supine position, half an hour after position change. at the
end of surgery before position alternation and before emergence from
anaesthesia on supine position. At each estimation of MP, mean arterial
pressure (MAP) and heart rate (HR) were recorded. |
