Comparative circulatory effects of adrenaline and noradrenaline during intra-osseous dental anaesthesia.
The effects of intra-osseous dental anaesthesia on heart rate and blood pressure was examined in 17 healthy volunteers. Adrenaline containing anaesthetic solutions were accompanied by increased heart rate and elevated systolic blood pressure which were not acceptable to a high proportion of subjects. Noradrenaline at the same concentration as adrenaline (1/80 000) usually decreased the heart rate and elevated the blood pressure. A few subjects experienced a feeling of weakness in the lower extremities when noradrenaline was injected. Endogenous catecholamine formation in these test conditions gave rise to insignificant circulatory effects.
