Comparative Study Clinical TrialLidocaine and prilocaine with vasoconstrictors as cause for cardiovascular reactions. A pulse oximetric study. Preliminary report.
Cardiovascular effects of two local anesthetic agent solutions containing 2% lidocaine with 1:80,000 epinephrine (LE) and 3% prilocaine with 0.54 microgram/ml felypressine (PF) used separately and in combination were observed. We made 38 separate monitoring sessions (30 minutes each) with healthy voluntary dental students. Participants were monitored with Cardiocap multiparameter physiological monitor. The monitored values were heart rate, systolic and diastolic blood pressure, SaO2 and peripheral blood flow. Values were registered into computer memory for further analysis. Group 1 received 7.2 ml of PF to the buccal sulcus just distal of the second upper right molar and 7.2 ml of LE to the left buccal sulcus ten minutes later. Group 2 had the same injection positions but they received 3.6 ml of PF to both sides of maxilla and then, ten minutes later, 3.6 ml of LE to each side. ⋯ Despite large doses of local anesthetics SaO2, systolic and diastolic blood pressure showed no clinically important changes, which suggests that local anesthetics have only a minimal effect on parameters mentioned above. This means that if the effect of one local anesthesia preparate (PF) is not sufficient, it is possible to safely reinforce the anesthesia with another substance (LE) in young healthy patients. Additionally, heart rate and pbf demonstrated quite clearly the symphatetic stimulation effect of the stress of injection and the stimulating action of epinephrine was seen clearly in heart rate values in both groups.

Case ReportsIntroduction of a new patient monitoring system during dental procedures: pulse oximetry.
This paper describes three cases of early detection of hypoxia with pulse oximeter during intravenous sedation. In the main study group over 40 patients were monitored by pulse oximetry during large dental operation under i.v.-sedation. Diazepam with soybean oily solvent and midazolam were used as intravenous sedative agents in this study. ⋯ Two of the patients received an injection of benzodiazepine antagonist, too. One patient needed further follow up but non of these patients developed any additional complications. As a conclusion pulse oximetric monitoring was found to be extremely sensitive as a predictor for coming complications as well as allowing early intervention in ventilation problems.
