RESUMO
Objective To investigate the effects of ginkgo biloba extract on the early postoperative cognitive function and the serum neuron specific enolase (NSE),S100β,tumor necrosis factor-α (TNF-α),interleukin (IL)-6,superoxide dismutase (SOD) and malondialdehyde (MDA) in patients with meningioma resection.Methods 60 patients with meningioma scheduled for elective intracranial tumor resection were enrolled and randomly divided into two groups (n =30 each):ginkgo biloba extract group (group G) and control group (group C).Ginkgo biloba extract was infused intravenously 30 min before anesthesia induction in group G,while group C received the equal volume of normal saline.Venous blood sample were taken at three time points:30 min before induction (T1),extubation (T2) and 24 h after operation (T3)for determination of serum concentration of NSE,S100β,TNF-α,IL-6,SOD and MDA.Cognitive function was evaluated at 1 d before and 3 d after surgery using Mini-mental State Examination (MMSE),Wechsler Adult Intelligence Scale (WAIS) and Wechsler Memory Scale (WMS).Results Compared with T1,the concentration of NSE,S100β,TNF-α,IL-6 and MDA in serum were significantly increased at T2 and T3 in the two groups,while SOD was decreased (P ＜ 0.05).Compared with group C,the concentration of NSE,S100β,TNF-α,IL-6 and MDA were significantly decreased at T2 and T3 in group G,while SOD was increased (P ＜ 0.05).Compared with 1 d before surgery,the scores of MMSE,digit accumulation,digit breadth (forward),vocabulary association and digit symbol replacement were significantly decreased and tracing connection time was significantly increased on the 3rd day after surgery in the two groups.The scores of digital breadth (reverse) and visual regeneration were significantly decreased in group C (P ＜ 0.05).Compared with group C,the scores of digit accumulation,digit breadth (forward and reverse) and visual regeneration were significantly increased on the 3rd day after surgery in group G (P ＜ 0.05).The incidence of postoperative cognitive dysfunction (POCD) at 3 d after surgery in group G was significantly lower than group C (P ＜ 0.05).Conclusions The pretreatment of ginkgo biloba extract can decrease the incidence of early POCD in patients with meningioma resection,and its mechanism may be related to the reduction of inflammatory reaction and antioxidation.
RESUMO
Objective To explore the value of Nacotrend and the degree and prognosis of disturbance of consciousness in craniocerebral injured patients. Methods Forty craniocerebral injured patients were observed and Nacotrend index (NI) and Glasgow Coma Scale (GCS) were evaluated 24 h after the operation. After followed up for 3 months, the patients with Glasgow coma scale (GOS) 4-5 scores were enrolled into in good recovery group and the patients with GOS 1-3 scores were enrolled into bad recovery group. The correlation of NI and prognosis was analyzed. Results There were 17 cases in the good recovery group, and 23 cases in the bad recovery group. Pearson correlation coefficient of NI and GCS was 0.721, P<0.01. The level of NI in good recovery group was 64.26±12.73, in bad recovery group was 29.57±8.12, and there was significant difference (P<0.05). Conclusion NI can be used in coma patients for consciousness grading assessment and also can correctly evaluate the prognosis.
RESUMO
Objective To evaluate the efficacy of penehyclidine hydrochloride for prevention of postoperative pulmonary complications (PPC) in patients undergoing brain glioma resection.Methods Seventy ASA class Ⅱ-Ⅲ patients,aged 30-69 years,weighing 50-80 kg,undergoing brain glioma resection,were divided into 2 groups by random digits table method:control group (group C,35 patients) and penehyclidine hydrochloride group (group W,35 patients).The patients in two groups were given the same methods of anesthesia induced and maintain.The patients in group W were given penehyclidine hydrochloride[20 μ g/kg(2 ml)] before anesthesia induced 30 min,meanwhile the patients in group C were given equal volume of saline.The occurrence of PPC was recorded within 72 h after operation and compared between two groups.Results The incidence of PPC in group W was significantly lower than that in group C [11.4％ (4/35) vs.28.6％ (10/35)] (P ＜ 0.05).Conclusion Intramuscular of penehyclidine hydrochloride 20 μ g/kg before operation can prevent the occurrence of PPC in patients undergoing brain glioma resection.
