Perbezaan antara anestesia tulang belakang dan anestesia epidural

Anestesia tulang belakang dan anestesia epidural tergolong dalam anestesia tulang belakang, sejenis anestesia tempatan

Anestesia epidural ialah suntikan larutan ubat ke dalam ruang epidural (ruang berpotensi antara dura dan ligamentum flavum), dan anestetik tempatan yang meresap menolak rongga melalui foramen intervertebral. Anestesia akar saraf. Dos adalah 5 hingga 10 kali lebih besar daripada anestesia tulang belakang, permulaannya lebih perlahan (15 hingga 20 minit), tiada kerosakan pada dura, dan ia tidak menyebabkan sakit kepala selepas anestesia. Ruang epidural tidak dikomunikasikan dengan rongga tengkorak, dan tahap suntikan boleh setinggi tulang belakang serviks, tanpa melumpuhkan pusat kehidupan medulla oblongata. Jika kateter diletakkan, suntikan berulang boleh memanjangkan tempoh bius. Anestesia epidural boleh membius saraf simpatetik, membawa kepada vasodilatasi periferi dan kemurungan miokardium, mengakibatkan penurunan tekanan darah.

Subarachnoid anaesthesia (spinal anaesthesia) injects local anesthetic into the subarachnoid space (the solid space between the arachnoid and pia mater and filled with cerebrospinal fluid) through the lumbar space to block the Because this cavity is connected with the ventricle, the excessive rise of the anesthesia level will lead to paralysis of the life center of the medulla, resulting in cardiac and respiratory arrest. During spinal anesthesia, because the sympathetic nerve is blocked, it is often accompanied by a drop in blood pressure, which can be prevented by ephedrine. In addition, because the dura is punctured, the cerebrospinal fluid leaks, resulting in a decrease in pressure, which is easy to cause headaches after anesthesia. The specific gravity of the liquid medicine and the patient's position will affect the level of the liquid medicine. If the drug is dissolved in the released cerebrospinal fluid, the specific gravity is higher than that of the cerebrospinal fluid. Dissolved in distilled water, the specific gravity is lower than that of cerebrospinal fluid. The high specific gravity liquid is used for sitting patients, and the liquid will sink to the cauda equina, which is safe and effective.
