The effects of isoflurane-induced hypotension on oxygen delivery,oxygen consumption and oxygenation during cerebral aneurysm operation |
|
| Abstract: | Objective To study effect of isoflurane induced hypotension on hemodynamics and oxygen delivery (DO 2),oxygen consumption (VO 2),VO/DO 2 ratio (ERO 2) and oxygenation during cerebral aneurysm operation.Methods Twenty one cerebral anuerysm patients were operated on under general anesthesia Inhalation concentration of isoflurane was elevated to reduce MAP by 30% 40% during dissection and occlusion of the aneurysm ,and was maintained for 30 45min. Hemodynamic values were measurd with Swan Ganz technique. Hemodynamics,oxygen kinetics and the blood level of lactate were tested during isoflurane deliberated hypotension. Results No significiant changes of CO,CI,SV,SI,RVSWI,HR and ECG tracing were observed during hypotension (P<0 05) SVR,PVR,Cpp,RPP and LVSWI were significantly decreased during hypotension,(P<0 05) During controlled hypotension DO 2 and S v O 2 decreased significiantly, ERO 2 increased significiantly and VO 2 and plasma lactate concentraion remained unchanged.Conclusion Isoflurane induced hyppension can keep a good balance between DO 2 and VO2, during cerdbral aneurysm operation |
