Lidocaine with epinephrine effect on arterial tension of children

to determine the effect of the epinephrine-lidocaine anaesthetic solutions on blood pressure in healthy children subjected to short dentistry procedures. we performed a prospective, observational and analytical study in 39 children with 7 and 8 years of age, who were subjected to dentistry treatment of short duration in a dentistry service. The blood pressure was measured in three times: previous to the infiltration of lidocaine to 2 % with epinephrine; 10 minutes later; at the end of procedure. the systolic blood pressure, like diastolic and the average increased after 10 minutes of the infiltration with the anesthetic-vasoconstrictor solution, but this difference was not significant (p = 0.39, 0.14 and 0.40). We observed an increase of the systolic (6.0 mm Hg, 95 % CI = 4.6-7.5, F = 14.0, p = 0.0001), diastolic (9.9 mm Hg, 95 % CI = 7.3-12.5; F = 26.0, p = 0.0001) and average arterial tension (7.3 mm Hg, 95 % IC = 5.8-8.8; F = 23, p = 0.0001) to the 10 minutes after the treatment. the use of the epinephrine-lidocaine anaesthetic solutions does not have significant effect on the blood pressure of children subjected to short dentistry procedures.
