OBJECTIVES: This study analyzes
hemodynamic changes in
patients with cardiac valvular
diseases submitted to dental
treatment under
local anesthesia containing
epinephrine .
METHODS: This randomized
clinical trial was performed at the Dental Division of the Instituto do Coração do
Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (
Brazil ).
Patients were
separated into two groups with the help of an aleatory number table 2 percent plain
lidocaine (PL, n= 31) and 2 percent
lidocaine with
epinephrine (1100,000) (LE, n= 28).
Blood pressure ,
heart rate ,
oxygenation and
electrocardiogram data were all recorded throughout the
procedure .
State and trait
anxiety levels were measured.
RESULTS: Fifty-nine
patients were selected for the LE group (n=28), with an average age of 40.3 ± 10.9, or for the PL group (n=31), age 42.2 ± 10.3. No differences were shown in
blood pressure ,
heart rate and
pulse oximetry values before, during and after
local anesthesia injection between the two groups.
State and trait
anxiety levels were not different. Arrhythmias observed before
dental anesthesia did not change in shape or
magnitude after treatment . Complaints of
pain during the dental
procedure were more frequent within the PL group, which received a higher amount of
local anesthesia .
CONCLUSION: Lidocaine with
epinephrine (1100,000) provided effective
local anesthesia . This
treatment did not cause an increase in
heart rate or
blood pressure and did not cause any arrhythmic changes in
patients with cardiac valvular
diseases .
