Cardiopulmonary Changes after Dental Procedures with Adrenaline Containing Local Dental Anesthesia

Background: The injection of adrenaline containing local dental anaesthesia may be associated with variable adverse effects on the cardio- respiratory system that are clinically undetectable.

Methods: The present study was conducted on 60 male patients who received adrenaline containing local dental anaesthesia, and 30 male patients who did not receive local dental anesthesia as a control group. Careful history taking, clinical examination, heart rate, SBP, DBP, MBP, respiratory rate, spirometry to measure FEV1, PEF, and oximetry to measure O2 saturation before and 15 minutes after dental procedures were obtained.

Results: Our results showed high statistical significant increase in HR, SBP, DBP, MBP, RR, and decrease in O2 saturation, FEV1, and PEF after dental procedures with adrenaline containing local dental anesthesia compared to baseline values in patients group, and a high statistical significant increase in RR only after dental procedures in control group.

Conclusion: Dental procedures with adrenaline containing local dental anesthesia have a stressful effect on the cardio respiratory systems as evidenced by the statistically significant increase in HR, SBP, DBP, MBP, RR, and statistically significant decrease in O2 saturation, FEV1, and PEF after dental procedures compared to baseline values.
