Dosis Aman Adrenalin dalam Larutan Anestesi Lokal untuk Penderita Hipertensi

Abstract

The treatment of patients with hypertension is increasingly common. Hypertensives are a problem because they exhibit a great lability of a blood pressure. The anticipation of dental treatment causes an initial elevation of the blood pressure which may be heightened by the stimulus of an injection or dental treatment. However, probably the underlying causes is endogenous adrenaline. Adrenaline is the most potent and efficient of vasoconstricting drug used in dental anesthetic solution. Lidocaine causes vasodilation, without adrenaline lidocaine is rapidly absorbed from the administration site. Vasoconstrictors are important additions to local anesthetic solutions. They improve the quality of pain control and its duration while decreasing the potential toxicity of the local anesthetic. Observation of dental clinic patients at Loma Linda University confirm the fact that the blood pressure is not elevated by the small amount of vasocontrictor (1:100,000) contained in the most commonly employed dental anesthetic solution. All of the adrenergic amines can produce potentially dangerous cardiovascular effect and elicit disturbing subjactive response when high blood concentration are obtrained. For these reasons Felypressin a nonsymphatomimetic amine alternative for vasoconstriction has been used. An aspirating syringe should be used to avoid the risk of intra vascular injection when administering a local anesthetic solution and it is considered advisable to avoid adrenaline if the hypertension is not controlled.
