Effects of total intravenous anesthesia and combined intravenous and inhalation anesthesia on blood glucose and cortisol in spinal neurosurgery / 中国医师进修杂志

Objective To investigate the effects of total intravenous anesthesia (TIVA) and combined intravenous and inhalation anesthesia on blood glucose and cortisol in spinal neurosurgery.Methods Forty-four spinal neurosurgery patients were divided into propofol combined with remifentanil group (PR group) and sevoflurane combined with remifentanil group (SR group ), 22 cases in each group,they were induced with propofol, sufentanil and rocuronium. Anesthesia was maintained with sevoflurane in SR group while propofol in PR group. Depth of anesthesia adaption according to bispectral index (BIS)(45 -55). Blood glucose, cortisol, haemodynamics were observed at different time points. Results The mean arterial pressure(MAP) was higher after induction in PR group than that in SR group(P ＜ 0.05 ). Sixty minutes after induction, MAP was lower than that before induction in PR group (P ＜ 0.05 ). Heart rate ( HR )in both SR group and PR group were lower at 60 and 120 minutes after induction than those before induction (P ＜ 0.05). HR was lower at 5 minutes after induction in PR group than that in SR group (P ＜ 0.05). No significant difference was showed in blood glucose and cortisol between the two groups (P ＞ 0.05 ). Cortisol level was significantly lower at 120 minutes after induction than that before induction [(40.6 ± 18.3) μg/L vs. ( 129.7 ± 36.7 ) μg/L, P ＜ 0.05 ] and at 24 hours postoperative [ (93.6 ± 19.8 ) μg/L ] recovered to the level before induction in PR group. Cortisol level was significantly higher before induction than 120 minutes after induction [ ( 130.5 ± 32.1 ) μg/L vs. (51.6 ± 16.8 ) μg/L, P ＜ 0.05 ] and 24 hours postoperative was (75.9 ± 18.2) μg/L in SR group. Conclusions Two anesthetic regimens are compatible during spinal neurosurgery, with no apparent fluctuations of perioperative blood glucose. However, longer cortisol inhibition is probably happened when using sevoflurane.

Discussion on etiology,pathogenesis and therapeutic method of exogenous cough in Lingnan Areas / 中华中医药杂志

According to the unique geographical conditions,climatic factors,human constitution,dietary custom,social environment and so on,the main etiology of exogenous cough in Lingnan areas is pathogenic dampness;and the main pathogenesis is phlegm-dampness internal retention and impaired and descending of lung.The syndrome of phlegm-dampness and syndrome of phlegm-heat are more common clinical types.We propose eliminating dampness and resolving phlegm,dispersing and descending lung qi as its main therapeutic methods.For chronic cough,it often have to take the therapeutic methods of strengthening spleen and nourishing lung.
