Knowledge of local anesthetics anaphylaxis among dental practitioners in a Nigerian tertiary hospital.
Keywords:local anaesthetic, anaphylaxis, awareness, dental
Background: Anaphylaxis is an acutely presenting lifethreatening
medical emergency. Studies have shown
that dentists feel inadequately able to recognize and
treat anaphylaxis. This study aims to determine the level
of knowledge of local anesthetic (LA) anaphylaxis
among dentists in a Nigerian Teaching Hospital.
Methods: This cross-sectional, questionnaire-based
study was conducted among dental practitioners at the
Dental complex of the University of Benin Teaching
Hospital, Nigeria from August 2020 to January 2021.
The questionnaire consisted of 21 items divided into
four main sections: (1) Demographic characteristics, (2)
general knowledge on local anesthetic anaphylaxis, (3)
knowledge on signs and symptoms of local anesthetic
anaphylaxis, (4) knowledge on treatment of local
anesthetic anaphylaxis. Data was analyzed using
Statistical Package for Social Sciences version 20.0,
IBM, Armonk, NY, USA.
Results: The 101 respondents approached agreed to
participate in the study. There were more males (64.4%)
compared to females. Majority of the respondents were
aged 30 -39 years. None of the respondents knew
completely all the signs and symptoms of anaphylactic
reaction from LA. None of the respondents got the
complete drugs to be kept in the office for LA
anaphylaxis. Less than half (43.6%) of the respondents
knew that epinephrine is the drug of first choice for
anaphylactic reactions. Only 50(49.5%) of the
respondents knew that the best route for epinephrine
administration is intramuscular route.
Conclusion: Adequate knowledge on anaphylaxis from
local anesthesia is lacking among dental practitioners in
