Rahianestezie

anestezie regionala a abdomenului si membrelor inferioare prin injectarea unui anestezic in canalul rahidian. rahianestezia este utilizata in chirurgia aparatului urinar jos (vezica), a aparatului genital feminin, a anusului si a membrelor inferioare. Rahianestezia are un efect mult mai rapid decat anestezia peridurala, dar, spre deosebire de ea, nu poate fi practicata pentru operatii cu durata mai mare 2,5 ore.

Principiu - Se injecteaza un anestezic local in lichidul cefalorahidian, la inaltimea radacinilor nervoase ale cozii de cal. Dupa cateva minute se instaleaza un blocaj senzitiv si motor complet al partii de jos a corpului, intinzandu-se pe o regiune mai mare sau mai mica, neurcand mai sus de partea inferioara a abdomenului.

Desfasurare - Rahianestezia este realizata dupa instituirea unei perfuzii intravenoase. Bolnavul este asezat pe marginea mesei de operatie sau culcat pe o parte. Dupa introducerea prin piele, intre doua vertebre lombare, a unui trocar (ac gos tubular destinat sa ghideze traiectul) se infige usor prin trocar un ac fin pana cand lichidul cefalorahidian reflueaza, apoi se injecteaza anestezicul prin acul fin cu ajutorul unei seringi.

Efecte nedorite - Acestea sunt foarte rare si pot surveni in timpul anesteziei sau in orele urmatoare: greturi si varsaturi, scaderea tensiunii arteriale, retentia pasagera a urinei, dureri de cap.
