Hemodynamic Effects of 2% Lidocaine with 1:80000 Epinephrine in Inferior Alveolar Nerve Block

Dental Research Journal (2006)

Abbas Haghighat Nasser Kaviani R Ali Panahi

Introduction Lidocaine plus epinephrine is the most common anesthetic drug used in dentistry which has important cardiovascular side-effects like increase in blood pressure and cardiac arrhythmia. The goal of this study was to evaluat cardiovascular effects of one cartridge of 2% lidocaine + 1:80000 epinephrine. Methods and Materials 60 Cases without any systemic diseases who had been admitted for right and lower molar tooth extraction were studied. For all of them, inferior alveolar nerve was blocked with one cartridge of %2 lidocaine + 1:80000 epinephrine. Blood pressure and pulse rate were measured with Omron digital sphigmomanometer (model M4) and recorded in 5 stages (At the admit time until 10 minutes after injection), and compared with together. Results The findings of our study showed that injection of one Cartridge of 2% lidocaine + 1:80000 epinephrine has negligible effects on blood pressure and pulse rate. Discussion Because of the minimum cardiovascular effects of one cartridge of %2 lidocaine + 1:80000 epinephrine in healthy cases, it seems tobe safe for patients with mild cardiovascular disease. Key words Epinephrine, Lidocaine, Blood Pressure, Pulse Rate.

Introduction: Implant surgery involves local anesthesia and drilling for implant placement, which might influence blood supply of the adjacent tooth. This study evaluated oxygen saturation changes of healthy adjacent tooth with pulse oximetry during implant surgery. Materials and methods: Fifteen healthy adult patients, who were candidate for anterior implant sugary and had at least one healthy anterior adjacent tooth, were selected. Surgery was carried out after lidocaine/epinephrine local anesthesia. At four stages before local anesthesia injection and after injection, oxygen saturation of the healthy adjacent tooth and peripheral oxygen supply were measured. Data was analyzed with paired samples t-test. Results: The mean peripheral blood oxygen saturation before local anesthesia was 98.2%, with no changes during and after surgery. In the teeth the mean of oxygen saturation was 87.73% before local anesthesia, which decreased to 79.27% after surgery, demonstrating a statistically significant difference; at other intervals no significant differences were observed between oxygen saturation values before and after local anesthesia. Conclusion: After local anesthesia injection there was a transient decrease in oxygen saturation in the adjacent tooth. It is not clear whether this decrease in the blood supply of adjacent tooth is clinically important or not; therefore, more studies are necessary. Key words: Dental pulp, Implant, Pulse oximetry.

Introduction: Severe gagging in some patients during dental procedures can complicate the procedure. In this study, the effect of oral ondansetron and placebo, as antiemetic medications, on gag reflex was evaluated with the stimulation of soft palate and palatine tonsil areas to simulate the clinical situation during dental procedures. Materials and methods: In this clinical trial, 88 healthy adult individuals were randomly divided into two equal groups of ondansetron and placebo, which were administered orally. Gag reflexes were checked using a tongue depressor and recorded before and 90 minutes after intervention in the soft palate and palatine tonsil areas. Data was analyzed and compared with SPSS software, using Mann-Whitney and Wilcoxon tests (α = 0.05). Results: In the ondansetron group a statistically significant decrease in gag reflex was noted after intervention in both soft palate and tonsil areas (p value < 0.05); however, no significant decrease was observed in the placebo group in the two areas after intervention. Conclusion: The results of the present study showed the efficacy of ondansetron in reducing the severity of gag reflex in both the soft palate and tonsil areas; therefore, its administration can be considered in clinical procedures in those areas. Key words: Dentistry, Gag reflex, Ondansetron.

The effect of orally administered ketamine on requirement for anesthetics and postoperative pain in mandibular molar teeth with irreversible pulpitis

Journal of Oral Science (2011)

Nasser Kaviani Abbasali Khademi Iraj Ebtehaj Zahed Mohammadi

Achieving successful anesthesia and pain control in a predictable, efficient manner is a challenge in the endodontic treatment of vital inflamed lower molars. The aim of this study was to evaluate the effect of oral ketamine on the dosage of local anesthetics required and postoperative pain management for irreversibly inflamed mandibular molars. In this randomized double-blind placebo-controlled clinical trial, 36 patients with irreversibly inflamed mandibular molars were randomly divided into two groups of 18. Ten mg of ketamine dissolved in 20 ml of fruit juice was administered orally to patients in the experimental group. The control group was given 20 ml of fruit juice alone as a placebo. After 30 min, inferior alveolar nerve block (IANB) anesthesia was induced using one cartridge of 2% lidocaine and 1:100000 epinephrine. Teeth were tested after 5 to 10 min using an electrical pulp tester. In patients showing a positive response, another IANB injection was applied, and the total number of anesthetic cartridges used was recorded. Postoperative pain was evaluated using a visual analogue scale (VAS). In addition, use of analgesic in the first 24 h after treatment was monitored using a questionnaire. Data were analyzed by t test using SPSS software. There were no significant differences in age or gender between the two groups. The number of anesthetic cartridges used in the ketamine group was significantly less than that in the control group (P = 0.003). Furthermore, postoperative pain in the ketamine group was significantly lower (P = 0.019). Also the number of analgesic tablets taken in the ketamine group was significantly lower (P = 0.011). It can be concluded that a low dose of ketamine might be beneficial for enhancing the effect of local anesthetics. (J Oral Sci 53, 461-465, 2011)

Effect of Dexmedetomidine Added to Lidocaine Cartridge on the Level of Patient Sedation, Cooperation, and Patient and Surgeon Satisfaction during Mandibular Third-Molar Extraction Surgery: A Randomized Double-Blind Controlled Trial

International Journal of Dentistry (2022)

Milad Etemadi Sh Nasser Kaviani Kimia Salimian Golnaz Tajmiri

Various methods have been introduced for anxiety control during third-molar extraction surgery. Dexmedetomidine (DEX) is known to have analgesic, anxiolytic, and sympatholytic properties with minimal adverse effects. This study aimed to evaluate the impact of the local injection of the combination of DEX and Lidocaine on patients' anxiety and the surgeon's satisfaction during third-molar extraction surgery.A total number of 26 healthy volunteers with symmetrical bilateral impacted mandibular third-molar teeth indicated for surgical removal were included in this double-blind randomized controlled trial. A single experienced surgeon performed two surgical extraction procedures within at least four-week time intervals using anesthetic cartridges containing "DEX + LIDO" or "LIDO alone" used randomly on each side for each patient. The Visual Analog Scale and the SDFQ index were used to evaluate patients' anxiety and surgeon satisfaction during the procedure.SDFQ reports showed that patients in the "DEX" group were 1.5 times more relaxed than those in the "LIDO alone" group. As a result, the level of sedation was considered statistically significant between the two groups (Wilcoxon test, P value <0.019). Wilcoxon test results also showed significant differences between the two groups regarding patients' overall cooperation in terms of interfering movement and verbal presentation of discomfort (P value <0.05); however, this difference was not considered significant regarding nonverbal signs of discomfort (P value >0.05). Moreover, both the surgeon and the patients reported a significantly higher satisfaction rate in the DEX group (paired T-test, df = 25, P value <0.05).It was inferred from the outcomes of the present study that the application of DEX added to the LIDO local anesthesia cartridge could significantly benefit anxious patients with previous unpleasant dental treatment experiences.

: Introduction: Changes in saliva and its biochemical content in diabetic patients can effect on supportive dental tissues and cause dental damage. Low carbohydrate diets, and good control of disease can reduce dental damage in diabetics. The aim of this study was to compare dental damage in patients with non-insulin dependent diabetes mellitus (NIDDM) patients and healthy individuals. Methods: In this case-control study, a number of 151 NIDDM patients aged 35- 80 years were the case group and the same number of healthy people referred to dental clinic were selected as control group. Both group’s oral cavity was examined and DMFT index in the groups was compared. T-test and correlation coefficient were used to analysis the data. Results: The average of DMFT in NIDDM patients was 16±7.79 that was significantly more than in healthy people (P patients and healthy people did not differ significantly, but the average of missing teeth in NIDDM patients was significantly higher than that in healthy people (P Conclusion: Higher DMFT index and number of missing teeth in NIDDM patients my be due to effect of the disease on saliva, the dental supportive tissue and poor oral hygiene in these patients or progressive caries of teeth that leads to end stage of dental life and extraction of teeth.

Effects of remifentanil on the recovery quality among pediatric candidates for dental procedures under general anesthesia

Dental Research Journal (2022)

Reza Salari-Moghaddam Nosrat Nourbakhsh Nasser Kaviani Shirin Marzoughi

Remifentanil is a short-acting synthetic opioid, seems to facilitate hospital discharge, induce less agitation and better recovery quality. The aim of this study was to investigate the effects of remifentanil on the quality of recovery among healthy children who were candidate for dental procedures under general anesthesia.This study was a double blind randomized controlled clinical trial on healthy children who referred to the Department of Pediatric dentistry, School of Dentistry, Isfahan University of Medical Sciences. Both groups were anaesthetized using 5 mg/kg thiopental sodium, 1 μg/kg fentanyl and 0.6 μg/kg atracurium. The first group received propofol to maintain anesthesia and the second group was given remifentanil along with propofol. Then, the time span to regain consciousness, level of agitation during recovery and time of discharge were monitored and compared between the two groups. Data were analyzed using the Mann-Whitney U-test, and the Kruskal-Wallis test at P < 0.05 level of significance.Findings showed that the propofol + remifentanil group recovered faster than the propofol group. Chi-square test showed a significant difference in recovery time between the two groups (P < 0.05). About 45 min after regaining consciousness, the mean pediatric anesthesia emergence delirium score in the propofol group was 4.02 ± 2.19 and was significantly higher than the propofol + remifentanil group (3.02 ± 2.83) (P < 0.05). In addition, the mean Postanesthetic Discharge Scoring System score in the propofol group was 6.04 ± 1.74 and was significantly higher than the propofol + remifentanil group (7.58 ± 2.14) (P < 0.05).Combination of propofol and remifentanil significantly reduced the time taken for recovery, discharge and agitation level compared to propofol.

The Efficacy of Two Intravenous Sedative Drugs in Management of Uncooperative Children for Dental Treatments.

PubMed (2015)

Nasser Kaviani Sanaz Ashrafi Seyed Ebrahim Jabbarifar Elham Ghaffari

Some children do not show an appropriate cooperation with their dentist. A number of them cannot be managed by local anesthesia and the usual techniques used to control behaviors, so further steps are required to control their pain and anxiety. Pharmaceutical control is recommended through sedation or general anesthesia.This study was aimed to evaluate two groups of drugs in intravenous sedation method.In this clinical trial intervention study, patients were randomly divided into two groups of 18 and 20 and each group received either intravenous midazolam-ketamine or midazolam-fentanyl. During the procedure, 0.25mg midazolam was administered to both groups if needed. The scores of intraoperative sedation and operation conditions were evaluated and recorded by dental sedation teacher groups (DSTG) system in the 10(th), 20(th), 30(th) and 40(th) minutes of the operation. The results were analyzed by SPSS (version 16) using independent T-test, Wilcoxon, Mann-Whitney and Pearson Chi-Square tests as appropriated.There was no significant difference between the two groups in sedation period (p= 0.55), recovery time (p= 0.18), Frankl score (p= 0.83(, score of intraoperative sedation and operating conditions (p> 0.05), and sedation complications (p= 0.612). In addition, no complication occurred in recovery.There was no significant difference between the two drug groups; both were appropriate in controlling children's behavior.
