- 摘要：Background
Tourniquet deflation during lower extremity surgery affects the hemodynamics and metabolism of the patient, which can affect brain activity. This study examined the changes in brain activity during tourniquet deflation by measuring the bispectral index (BIS).
MethodsThe BIS was measured during surgery in forty patients who had received knee arthroscopic surgery under general anaesthesia. The BIS was measured 5 minutes before deflation (DB5) and 5 minutes after deflation (DA5).
ResultsThe BIS at DB5 and DA5 was 50.2 ± 9.9 and 44.4 ± 10.4, respectively. The BIS of DA5 was significantly lower than that of DB5 (P < 0.05).
ConclusionsTourniquet deflation during lower extremity surgery decreases the BIS associated with hemodynamic and metabolic changes. However, its clinical significance in neurologically critical patients, such as geriatric or neurologically disabled patients, remains to be clarified.
