Title
Methemoglobin Levels in Generally Anesthetized Pediatric Dental Patients Receiving Local Anesthetics
NCT number
NCT01402869
Status
Completed
Phases
Not applicable
Enrollment
91 participants, actual
Lead sponsor
Loma Linda University
Conditions
Methemoglobinemia
Interventions
4% prilocaine plain, 2% Lidocaine with 1:100,000 epinephrine

Limitations and caveats
Did not compare locals anesthetics with equivalent concentrations of epinephrine; unable to control length of time methemoglobin blood levels were monitored as all subjects varied in extent of restorative dental procedures needed.

Registered outcomes3

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryPeak Methemoglobin Blood LevelsMeasured at 10 second intervals during dental treatment for an average of 2 hoursThe maximum percentage of methemoglobin in blood
SecondaryTime to Peak Methemoglobin Blood LevelsMeasured at 10 second intervals during dental treatment for an average of 2 hours
The length of time between the administration of local anesthetic (Prilocaine and Lidocaine Groups) or start of restorative dental procedures (No local anesthetic Group) and the time at which the maximum methemoglobin blood level is observed.
SecondaryDelta Methemoglobin Blood LevelFrom administration of local anesthetic or start of restorative procedures to time at which maximum methemoglobin blood level was documented during dental treatment for an average of 2 hoursChange in percentage of methemoglobin in blood from baseline level to peak level
