ABSTRACT

Objective To explore effect of propofol or sevoflurane combined with dexmedetomidine on postoperative cognitive function , erythrocyte sedimentation rate and oxidative stress in patients with bone tumour .Methods 52 cases with bone tumor and requiring a surgery were selected and divided into sevoflurane group and propofol group randomly.The sevoflurane group were anesthetized with sevoflurane and dexmedetomidine.Propofol group were anesthetized with propofol and dexmedetomidine.The cognitive function score, recovery time, sedimentation value and oxidative stress level were compared after operation.ResuIts Compared with propofol group at the same time, the cognitive function score of patients in sevoflurane group at postoperative 6, 12, 24 h were higher (P<0.05) and restored to preoperative levels at postoperative 24 h (P<0.05) .The recovery time of spontaneous breathing, eyes open, remove endotracheal intubation and directional force in sevoflurane group were shorter than that in propofol group (P<0.05).Compared with propofol group at the same time, the erythrocyte sedimentation rate in sevoflurane group at postoperative 5, 10d were lower (P<0.05) and restored to preoperative levels at postoperative 10 d (P<0.05).Compared with propofol group postoperation, the superoxide dismutase (SOD) and methane dicarboxylic aldehyde (MDA) levels in sevoflurane group were lower, total antioxidant capacity (T-AOC) level was higher (P<0.05).ConcIusion Sevoflurane has a smaller effect on postoperative cognitive function than propofol in patients with bone tumor, combined with dexmedetomidine, which has an important significance to clinical surgery.
