Orqa miya ignalari va epidural ignalar o'rtasidagi o'xshashlik va farqlar qanday
Mar 25, 2022
epidural behushlik
(epidural behushlik) - epidural bo'shliqqa (dura va ligamentum flavum o'rtasidagi potentsial bo'shliq) dorivor eritmani yuborish va diffuz lokal anestezik intervertebral teshikdan o'tadigan nerv ildizlarini anesteziya qiladi. Dozasi umurtqali anesteziyaga qaraganda 5-10 marta kattaroq, boshlanishi sekinroq (15-20 minut), duraga zarar etkazilmaydi va behushlikdan keyin bosh og'rig'iga sabab bo'lmaydi. Epidural bo'shliq kranial bo'shliq bilan aloqa qilmaydi va in'ektsiya darajasi medulla oblongatasining hayot markazini falaj qilmasdan, bachadon bo'yni umurtqasi kabi yuqori bo'lishi mumkin. Agar kateter qo'yilsa, takroriy in'ektsiya behushlik muddatini uzaytirishi mumkin. Epidural behushlik simpatik nervlarni behushlik qilishi mumkin, bu esa periferik tomirlarning kengayishiga va miyokard depressiyasiga olib keladi, bu esa qon bosimining pasayishiga olib keladi.
subaraknoid behushlik
(subarachnoid anaesthesia) referred to as spinal anesthesia (spinal anaesthesia) local anesthetic is injected into the subarachnoid space (the solid space between the arachnoid and pia mater, filled with cerebrospinal fluid) through the lumbar space to block the nerve roots in this area, Because this cavity communicates 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.
