The Effect of Local Anesthesia When Used in Dental Restorative Cases Under General Anesthesia on Control of Intraoperative Physiologic Parameters and Post-Operative Comfort
Master of Science in Dentistry
To determine the effect of local anesthesia on post-operative pain and physiologic parameters intraoperatively in patients undergoing dental care under general anesthesia.
This study was modeled as a double-blinded randomized control trial. Patients included healthy children under the age of six scheduled for restorative dental treatment under general anesthesia. Patient behavior was evaluated pre and post-operatively using the FLACC score and post-operatively using the Parental Pain Score Measure. Intraoperatively, all participants followed a standardized general anesthesia protocol and were given either local anesthetic infiltration by the dental surgeon performing the surgery or no anesthesia was utilized. Intraoperatively physiologic stability was observed during points of potential stimulation noted by fluctuations in heart rate, and respiratory rate, ETCO2.
No statistically significant differences in FLACC score and PPPM score were seen between the two treatment groups. Intraoperatively, patients treated with preemptive LA had statistically significant lower heart rates and ETCO2 than those patients who did not receive local anesthesia.
