Lidocaine yog ib qho tshuaj loog hauv zos, tseem hu ua sirocaine, uas tau hloov procaine nyob rau xyoo tas los no thiab tau siv dav rau kev siv tshuaj loog hauv zos hauv kev phais kom zoo nkauj.Nws thaiv cov hlab ntsha excitation thiab conduction los ntawm inhibiting sodium ion channels hauv paj hlwb daim nyias nyias.Nws cov lipid solubility thiab protein binding tus nqi siab dua cov procaine, muaj zog cell nkag tau, pib sai, lub sij hawm ntev ua hauj lwm, thiab ib qho kev siv zog plaub zaug ntawm procaine.
Kev siv tshuaj loog muaj xws li infiltration anesthesia, epidural anesthesia, anesthesia nto (xws li mucosal tshuaj loog thaum lub sij hawm thoracoscopy los yog phais plab), thiab cov hlab ntsha conduction thaiv.Txhawm rau kom ncua sijhawm ntawm kev siv tshuaj loog thiab txo cov kev mob tshwm sim xws li lidocaine lom, adrenaline tuaj yeem ntxiv rau cov tshuaj loog.
Lidocaine kuj tseem siv tau los kho ventricular premature beats, ventricular tachycardia, digitalis lom, ventricular arrhythmias tshwm sim los ntawm kev phais plawv thiab catheterization tom qab mob myocardial infarction, suav nrog ventricular premature beats, ventricular tachycardia, thiab ventricular fibrillation. nrog rau mob qaug dab peg uas tsis muaj txiaj ntsig nrog lwm cov tshuaj tiv thaiv kab mob thiab rau cov tshuaj loog hauv zos lossis txha caj qaum.Tab sis feem ntau nws tsis zoo rau supraventricular arrhythmias.
Kev tshawb fawb nce qib ntawm perioperative intravenous infusion ntawm lidocaine infusion
Perioperative siv cov tshuaj opioid tuaj yeem ua rau muaj ntau yam tsis zoo, uas txhawb kev tshawb fawb tob txog cov tshuaj tsis yog opioid analgesic.Lidocaine yog ib qho ntawm cov tshuaj muaj txiaj ntsig zoo tshaj plaws uas tsis yog opioid analgesic.Perioperative kev tswj hwm ntawm lidocaine tuaj yeem txo qis kev siv tshuaj opioid, txo qhov mob tom qab phais, ua kom rov qab ua haujlwm ntawm plab hnyuv ua haujlwm, txo qhov ntev ntawm kev nyob hauv tsev kho mob thiab txhawb kev kho mob tom qab phais.
Kev kho mob ntawm cov tshuaj lidocaine intravenous thaum lub sij hawm perioperative
1. Txo kev ntxhov siab thaum lub sij hawm phais phais
2. txo qhov kev siv tshuaj ntawm cov tshuaj opioid, txo qhov mob tom qab phais
3.Txhim kho qhov rov ua haujlwm ntawm lub plab zom mov, txo qhov tshwm sim ntawm xeev siab thiab ntuav (PONV) thiab kev paub tsis meej tom qab (POCD), thiab ua kom luv nyob hauv tsev kho mob.
4.Lwm txoj haujlwm
Ntxiv nrog rau cov teebmeem saum toj no, lidocaine tseem muaj cov teebmeem ntawm alleviating txhaj tshuaj ntawm propofol, inhibiting hnoos teb tom qab extubation, thiab alleviating myocardial puas.
