Abstract:
Objective:To investigate the relationship between propofol anesthesia maintenance and cerebral tissue edema after craniotomy and its protective effect on the brain.Methods:A total of 98 patients who received craniotomy in the Second Affiliated Hospital of Air Force Medical University from June 2022 to June 2023 were selected and divided into control group and observation group according to random number table method, with 49 cases in each group. Sevoflurane was inhaled to maintain anesthesia in the control group after tracheal intubation, and propofol was injected intravenously into the observation group after tracheal intubation. The indexes were compared between the two groups in terms of dynamic changes of cerebral tissue edema, intracranial pressure, brain injury factors [S100 calcified protein β (S100-β), neuron-specific enolase (NSE), glial fibrillary acidic protein (GFAP)], cerebral oxygen metabolism indexes [arterial blood oxygen content (AVDO 2), arterial blood lactic acid (AVDL), cerebral oxygen metabolism rate (CMRO 2)], oxidative stress indicators [malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px)]. Results:There were no significant differences in the degree of cerebral tissue edema, intracranial pressure, brain injury factors, cerebral oxygen metabolism indexes and oxidative stress indexes between the two groups (all P>0.05). There were significant differences in the degree of cerebral tissue edema, intracranial pressure, brain injury factors, cerebral oxygen metabolism indexes and oxidative stress indexes between the two groups after surgery (all P<0.05). The degree of cerebral edema in the observation group at 24 h and 72 h after operation was less than that in the control group, and the difference was statistically significant (all P<0.05). The intracranial pressure after craniotomy, before skull reduction and after operation in the observation group was lower than that in the control group, with statistical significance (all P<0.05). The serum levels of S100-β, NSE, GFAP in observation group were lower than those in the control group after craniotomy, before skull reduction and after operation, and the difference was statistically significant ( P<0.05). AVDO 2, AVDL, CMRO 2 of the observation group after craniotomy, before skull reduction and after surgery were better than those of the control group, with statistical significance (all P<0.05). In terms of oxidative stress indexes after craniotomy, before skull reduction and after surgery, MDA levels in observation group were lower than those in control group, while SOD and GSH-Px levels were higher than those in control group, the differences were statistically significant (all P<0.05). Conclusions:Propofol anesthesia maintenance can alleviate cerebral tissue edema after craniotomy, reduce intracranial pressure, reduce the release of brain injury factors, improve cerebral oxygen metabolism, enhance antioxidant capacity, and significantly protect the brain of patients.
