Introduction:
Prolonged local anesthesia is achieved by using long-acting local
anesthetics, as ropivacaine and bupivacaine. In different surgical
branches, longer absence of pain is noted after surgical intervention
when ropivacaine is used with dexamethasone than when it is used alone.
The aim of the study was to determine the effect on the duration
of local anesthesia with a combination of 0.75% ropivacaine with the
addition of dexamethasone during oral surgery interventions.
Material and methods: A total of 12 patients participated in the
study which was conducted at the Department of Oral Surgery at The
Dentistry Clinic in Niš, in 2017.Surgical interventions were performed
on both upper and lower jaw. Patients were divided into 2 groups: the
study group of 6 patients who received 4 ml of 0.75% ropivacaine
solution with addition of 1 ml/4mg dexamethasone and the control group
of 6 patients who received 4 ml of 0, 75% solution of ropivacaine
without the addition of dexamethasone. Statistical data was processed by
the SPSS 15.0 software.
The results: The onset time of first signs of anesthesia,
confirmed by testing sensibility of soft tissues (lip and gingiva), was
1,5 min in the study group and 2.66 in the control group. The time
necessary for the full effect of anesthesia to set in, i.e. total
insensitivity of soft tissues, was 3.5 min in the study group and 4.66
min in the control group. The duration of local anesthesia was 625,5 min
in the study group which is considered statistically significant (p <
0.01) and 290 min in the control group.
Conclusion: Small doses of dexamethasone added to local
anesthetics may reduce the need for additional anesthesia and analgesic
therapy within the first 24 hours after major oral surgery
interventions.
