问题 水肿的发病机制是什么?
选项
答案
解析 ①酸中毒和缺氧使脑血管扩张。②酸中毒和缺氧还能损伤血管内皮使其通透性增高,导致脑间质水肿。脑充血、水肿使颅内压增高,压迫脑血管,更加重脑缺氧。由此形成恶性循环,严重时可导致脑疝形成。

错误信息

  • 消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
