Regional anaesthesia involves the introduction of drugs with the intention of blocking the nerve supply to that part of the body, such as a limb, so the patient cannot feel pain in that area when a surgical operation is performed. Unlike general anaesthesia, the patient remains awake, leading to less side-effects and enabling the surgeon to converse with the patient during the procedure.
Regional anaesthesia is now more common than general anaesthesia for caesarian section.
In general, anesthesia patients are given a combination of gases through the respiratory system and/or drugs in the veins.
General anesthesia may be related to an increase in blood pressure while the anesthetic drug is induced.
If we can choose between general and regionalanesthesia, epidural anesthesia and postoperative analgesia (being awake but pain free) are believed to be preferable to standard general anesthesia for high-risk surgical patients.
