Kulwazi lwethu, olu luphononongo lokuqala olulindelekileyo olubonisa isiphumo seedosi ezahlukeneyo ze-lidocaine emithanjeni kwi-ED50 kunye ne-ED95 yedosi yokungeniswa kwepropofol kwizigulana eziphantsi kwe-hysteroscopy ye-trimester yokuqala.Iziphumo zibonise ukuba ukulawulwa kwe-intravenous ye-lidocaine kwi-dose ye-1.0 mg / kg ngaphambi kokuba i-injection ye-propofol inciphise kakhulu i-ED50, i-ED95 kunye ne-dose ye-propofol epheleleyo, elingana nomphumo we-dose ye-1.5 mg / kg.Ngoko ke sincoma i-dose ephantsi ye-1.0 mg / kg njengeyona dose efanelekileyo yonyango olusebenzayo lwe-anesthesia ye-intravenous kunye nepropofol.Samangaliswa ukufumanisa ukuba ukulawulwa kwe-intravenous ye-0.5 mg / kg i-lidocaine yokwandisa i-ED50 ye-propofol, ebonisa umphumo onzima we-lidocaine.
Ngenxa yokuqalisa ngokukhawuleza kwesenzo kunye nokubuyiswa ngokukhawuleza, ipropofol isoloko isetyenziselwa ukuxilisa kwiinkqubo zokuhlinzwa ezingaphandle.Nangona kunjalo, iidosi eziphezulu zepropofol zandisa umngcipheko we-apnea, ukuwa kwe-airway ephezulu, kunye ne-hypotension, ngelixa i-dose ephantsi ibangele ukungabikho ngokwaneleyo kwe-sedation.Ngoko ke, kukho imfuneko ye-adjuvant esebenzayo yokunciphisa impendulo yokuhlinzwa kunye nokunciphisa imfuno yepropofol.Kwiminyaka yakutshanje, uphando oluninzi luye lwabonisa imiphumo ye-analgesic ye-lidocaine ye-intravenous, kuquka ukunciphisa intlungu emva kwe-propofol injection, ukunciphisa iimfuno ze-opioid, kunye nokunciphisa intlungu engapheliyo emva kokuhlinzwa.Kwiingcebiso zabo zokuvumelana ezipapashiweyo, uFoo et al.cebisa ukuba idosi yokuqala ingabi ngaphezu kwe-1.5 mg/kg ebalwa kusetyenziswa ubunzima bomzimba obufanelekileyo ikhuseleke kwi-lidocaine emithanjeni.Kutshanje, uLiu et al.kunye noYu et al.wabonisa ukuba ukulawulwa kwe-lidocaine nge-intravenous ngaphambi kokungeniswa kwe-anesthesia kubangele ukuncipha kwe-ED50 ye-propofol kwi-gastroscopy kunye nezigulane ze-hysteroscopy.Ke, isifundo sethu sijolise ekuvavanyeni isiphumo seedosi ezahlukeneyo ze-lidocaine ye-intravenous kwi-propofol-induced ED50 kunye ne-ED95 ngexesha le-trimester yokuqala ye-uterine aspiration kunye nokumisela idosi efanelekileyo.Asibandakanyi izigulane ezinembali yokunikezelwa kwesisu kwaye ngubani oye wahlanjululwa ngumlomo wesibeleko phakathi kweenyanga ze-6 kuba sicinga ukuba izigulane ezinembali yokuhanjiswa kwesisu okanye imbali yokukhutshwa komlomo wesibeleko yayinokuvuselela okuncinci komlomo wesibeleko ngexesha lokuhlanjululwa kokuhlinzwa kunezigulane ezingenayo imbali yokutshatyalaliswa komlomo wesibeleko.ukwanda komlomo wesibeleko wesigulane.28 Oku kunokukhokelela kwiziphumo ezichaneke ngakumbi.
I-lidocaine ye-intravenous ine-half-life yemizuzu emi-5-8 kuphela, iqala kwi-vascular bed kwaye ingena kwii-tissue ze-peripheral, kuqala kwiindawo eziphakamileyo eziphezulu (intliziyo, imiphunga, isibindi, i-spleen), kwaye emva koko kwiindawo ze-hypoperfusion.imisipha kunye nezicubu ze-adipose).10 Kwisifundo sethu, silawula i-lidocaine ngaphambi kokuba i-propofol induction ukugcina i-plasma concentration yayo ngaphakathi koluhlu olusebenzayo.Ngenxa yoko, ukusetyenziswa kwe-1.5 mg / kg ye-lidocaine phambi kwepropofol kubangele ukunciphisa i-26% kwi-ED50 ye-propofol, kunye ne-1.0 mg / kg i-lidocaine yabangela ukunciphisa i-30%.Ezi ziphumo ziyangqinelana nezo zikaLiu kunye noXu, zibonisa ukuba i-lidocaine kula mayeza ineempembelelo ze-analgesic kunye ne-antihyperalgesic.Okumangalisayo kukuba, nangona kunjalo, i-ED50 yonyuswa nge-lidocaine ye-intravenous kwi-0.5 mg / kg, ebonisa ukuba umphumo we-0.5 mg / kg umthamo unokuguqulwa kwaye i-dose ephantsi kakhulu ye-lidocaine ye-intravenous inokudibaniswa nokusabela okubukhali kwe-hypersensitivity ehambelana ne-nervous. ukonwaba.I-Lidocaine isebenza kwiithagethi ezininzi ze-molecular ezibandakanyekayo kwi-nociception enzima kunye nengapheliyo, kubandakanywa i-N-methyl-D-aspartate (NMDA) kunye ne-muscarinic cholinergic (m1, m3) i-receptors, amaxesha angama-100-1000 anobucayi kunezinye iinjongo.I-20,29 I-NMDA, i-m1 kunye ne-m3 i-receptors zihlala zivakalelwa kwiimpawu ze-lidocaine ezingaphantsi kweekliniki ezifanelekileyo ze-plasma.I-Lidocaine inqanda ukusebenza kwee-receptors ze-NMDA zabantu kwii-nanomolar concentrations kunye ne-inhibition ephezulu kwi-millimolar range, okubangelwa ukukhululeka kweentlungu.I-Lidocaine isebenza kwi-muscarinic cholinergic receptors kwi-concentration- kunye nexesha elixhomekeke kwindlela.Claes et al.ibonise ukuba ukulawulwa kwe-intravenous ye-lidocaine kwi-dose ye-10 kunye ne-30 mg / kg yokwandisa ukukhululwa kwe-acetylcholine ye-intraspinal kunye ne-induced analgesia ephakathi ngokuvula i-muscarinic receptors kwiigundane, kodwa i-dose ye-1 mg / kg i-lidocaine ayizange ikhulise kakhulu ukukhululwa kwe-acetylcholine ye-intraspinal.Izifundo ze-30,31 nazo zibonise ukuba i-lidocaine ivimba i-m1 kunye ne-m3 i-muscarinic receptors kwiindawo eziphantsi kakhulu ze-nanomolar (IC50 ye-18 nM ye-m1 kunye ne-370 nM ye-m3).Ukongezelela, ukubonakaliswa kwexesha elide kwi-lidocaine kwi-IC50 kubangele ukuguqulwa kwe-biphasic ye-m1 kunye ne-m3 receptors kunye nokuvinjelwa kokuqala okulandelwa kwiiyure ze-8 kamva ngokunyuka kwezibonakaliso.32 Ngaloo ndlela, i-bolus yethu enye yeedosi eziphantsi kakhulu ze-lidocaine i-0.5 mg / kg ngaphandle kokuvezwa ixesha elide inokusebenza ngokuyinhloko ngokuvinjelwa kwe-m1 kunye ne-m3 receptors.Ukuvinjelwa kwe-m1 kunye ne-m3 i-receptors yavakaliswa ngakumbi, enokuthi ichaze ukwanda kwe-ED50 kwiqela le-L0.5 kwisifundo sethu.Nangona kunjalo, kwisifundo sethu, asizange silinganise i-plasma concentration ye-lidocaine.Uphando olongezelelweyo kunye nokuqinisekiswa kuyafuneka ukuze kuqinisekiswe le ngqikelelo.
I-dose ye-dose ye-propofol epheleleyo efunekayo kuwo wonke umsebenzi yayiphezulu kakhulu kumaqela e-L0 kunye ne-L0.5 kunamanye amaqela amabini.Ubuninzi bokudandatheka kokuphefumula kwiqela le-L0.5 laliphezulu kuneL0 kunye ne-L1.0 amaqela.Ukuncipha kwe-SBP emva kokungeniswa kwe-anesthesia kwiqela le-L0.5 lalilikhulu kuneqela le-L0.Akukho nasinye isigulana esaphuhlisa i-hypoxia, njengoko senza i-chin lift okanye i-mask ventilation ngexesha elifanelekileyo.Idosi eyandisiweyo yepropofol iyonke, ukuphindaphindeka kokudakumba kokuphefumula, kunye nokuncipha koxinzelelo lwegazi lwe-systolic emva kokungeniswa kwe-anesthesia kwiqela le-L0.5 likwacebise ukuba idosi ephezulu yepropofol inokunyusa umngcipheko wokuphefumla kunye noxinzelelo lokujikeleza.Kwakungekho nantlukwano kwizehlo zeziganeko ezimbi phakathi kwamaqela L0, L1.0 kunye ne-L1.5.Nangona kunjalo, ngokunikezelwa koyilo lwesifundo sethu, i-dose ye-propofol-inducing dose kwiqela ngalinye yayisondele kwi-ED50 kodwa ingaphantsi kwe-ED95.Ngaloo ndlela, iziganeko zeziganeko ezimbi zinokuba ziphezulu ukuba izigulane zeqela le-L0 zenziwe ngepropofol kwi-dose ye-ED95 (2.8 [2.6-3.2] mg / kg).Nangona kunjalo, umphumo we-lidocaine ubangele i-ED95 ye-2.0 (1.9-2.4) mg / kg kunye ne-2.1 (1.9-2.4) mg / kg kumaqela e-L1.0 kunye ne-L1.5, ngokulandelanayo, kwiidosi eziphantsi.Le ngxoxo ingentla ichaza ukuba kutheni sikholelwa ukuba i-analgesic effect ye-intravenous lidocaine kwimilinganiselo efanelekileyo kwaye ngexesha elifanelekileyo luncedo ekunciphiseni iingxaki ze-anesthesia ezibangelwa yi-propofol.Kwisifundo sethu, akukho ntlukwano ebalulekileyo kwi-ED50, i-dose ye-propofol iyonke, ixesha lokuvuka, kunye neziganeko ezimbi phakathi kwe-L1.0 kunye ne-L1.5 amaqela.Ngoko ke sincoma umthamo ophantsi we-1.0 mg / kg IV i-lidocaine njengeyona dose efanelekileyo.
Kukho imida kwisifundo sethu.Okokuqala, kuphela izigulane ezine-ASA I okanye i-II zifakwe kolu cwaningo, kodwa izigulane ezine-ASA III okanye i-IV zinokuthi zilungele ukuphefumla kunye nokudakumba kwentliziyo xa zithatha ipropofol.33 Ngaphezu koko, bonke abathathi-nxaxheba kolu phononongo babengabafazi abakhulelweyo, kwaye iziphumo zinokuthi zihambelane nokwahluka kwe-physiological, umahluko phakathi kwamadoda.Okwesibini, sisebenzisa amanqaku e-MOAA/S njengesalathisi senqanaba lokuthomalalisa kunezalathi zenjongo ezifana nokubeka iliso kwi-BIS.34 Okwesithathu, i-lidocaine ilawulwa njenge-bolus enye kwaye asizange silinganise amanqanaba e-plasma ye-lidocaine.Ekugqibeleni, i-ED95 igqitywe yi-ED50, ngoko uphando olongezelelweyo luyafuneka ukufumana idatha echanekileyo.
Iziphumo zophononongo lwethu lwangoku zibonise ukuba ukulawulwa kwe-intravenous ye-1.0 mg / kg ye-lidocaine ngaphambi kwe-propofol injection yanciphisa kakhulu i-ED50, i-ED95, kunye ne-dose ye-propofol epheleleyo kwizigulane ezihamba nge-first-trimester ambulatory hysteroscopy phantsi kwe-anesthesia, elingana nedosi esebenzayo ye-1.5 mg / ikg.Sithatha umthamo we-1.0 mg / kg ukuba ibe yi-dose efanelekileyo.Okumangalisa kukuba, umthamo we-intravenous we-0.5 mg / kg i-lidocaine yandisa i-ED50 ye-propofol, ebonisa umphumo onzima we-lidocaine.Uphononongo olongezelelweyo lweendlela ezisisiseko ziyafuneka ukuze kuqinisekiswe iziphumo zethu.
