拔牙打麻藥,對大腦有影響嗎?

拔牙打麻藥,對大腦有影響嗎?

            

                

                    

                        

                            

                                

                                    

                                        

                                            

                                                

                                                    


                                                        一般拔牙只需要局部麻醉是不會對大腦造成影響,只對拔牙附近牙齦起藥效,另外藥物都得經過血腦屏障這一關才能進入大腦。


                                                    


                                                        


                                                    


                                                        


                                                    


                                                        


                                                    


                                                        正常情況下打麻藥一支后,牙齦部分開始麻木,隨着藥效逐漸擴散,在2小時內拔牙過程舒服,幾乎沒有痛感,不過有些患牙拔除難度大,拔除時間較長,可能到後面藥效不明顯,得考慮打第二支麻藥。


                                                    


                                                        


                                                    


                                                        


                                                    


                                                        


                                                

                                            

                                        

                                        

                                            

                                                

                                                    

                                                        


                                                            大劑量進行局部麻醉會有危害嗎?


                                                    

                                                

                                            

                                        

                                        

                                            

                                                

                                                    


                                                        


                                                    


                                                        1、像這種拔牙小劑量就能麻醉完成手術,要是超過一定量的話,拔牙麻木效果明顯,智力方面倒沒事,但術后整個口腔會長時間沒有知覺,危害到牙神經,要等過幾天才會恢復,當然也得看注射的是什麼藥物。


                                                    


                                                        


                                                    


                                                        2、對於孩子乳牙時期拔牙,大多數可不用打麻藥,因為乳牙牙根隨着恆牙生長慢慢吸收消散,牙神經也是一樣會消失,一是拔牙時不會那麼痛苦,二是減輕恐懼心理。


                                                    


                                                        


                                                    


                                                        


                                                    


                                                        


                                                

                                            

                                        

                                        

                                            

                                                

                                                    

                                                        


                                                            拔牙之後會頭暈是怎麼回事?


                                                    

                                                

                                            

                                        

                                        

                                            

                                                

                                                    


                                                        


                                                    


                                                        1、第一跟你自身低血壓或者低血糖有關,一到拔牙精神緊張,加上身體虛弱,就會出現頭暈、四肢無力等併發症。第二也有可能是麻醉劑起的不良反應,不過不用擔心,拔牙劑量不大。


                                                    


                                                        


                                                    


                                                        2、拔牙前需要進食,最好吃些高蛋白的食物補充能量,比如阻生智齒這種早上可以拔除,局部麻醉後方便下午觀察創口情況,或者是有其它併發症,建議拔完較大的創口除了縫合,還得輸液消炎,不然很容易引起頭痛,甚至張口困難。


                                                    


                                                        


                                                    


                                                        


                                                    


                                                        


                                                    


                                                        拔牙后一定要注意飲食清淡,避免吃過辣等刺激性食物,這樣牙槽窩才會慢慢好轉。
