NCT ID: NCT05912335 Completed - Local Anesthesia Clinical Trials

Clinical Efficiency of Xanthan Hydrogels Containing Local Anesthetics Encapsulated in Nanostructured Lipid Carries

Start date: June 2, 2021
Phase: Phase 1
Study type: Interventional

In a crossover, randomized, placebo-controlled, double-blind study, 40 volunteers will receive the following formulations: hydrogels containing LAs (local anesthetic) - lidocaine and prilocaine (both at 2.5%) encapsulated in CLN (XAN-CLN) or not (XAN-CLN ), EMLA (topical anesthetic available on the market) and placebo hydrogel. The formulations will be applied for 2 minutes, bilaterally on the palatal mucosa (first premolar region), in two distinct sessions. Soon after removal of the topical formulation, an AL will be performed at the region using 0.3 mL of anesthetic solution at an injection speed of 1 mL/min. Pain resulting from needle insertion and LA injection will be measured using two visual analog scales (VAS).

NCT ID: NCT05793905 Completed - Local Anesthesia Clinical Trials

Buffered Anesthetic Solution in the Treatment of Mandibular Primary Molars

Start date: December 1, 2022
Phase: Phase 4
Study type: Interventional

In a prospective, randomized clinical trial, triple-blind, split-mouth study, 40 children aged between 7 to 10 with bilateral mandibular primary molars were diagnosed with pulpitis. The test agent was 2% lidocaine with 1:80.000 epinephrine buffered with sodium bicarbonate 8.4% at a ratio of 1/10, as opposed to the control agent, which was non- buffered 2% lidocaine with 1:80,000 epinephrine. The pain will be assessed during inferior alveolar nerve block injection (IANB) and the effectiveness of anesthesia using the subjective Wong-Baker visual analog scale, the objective sound, eye, and motor (SEM) scale, and the physiological pain scale (pulse rate) using a pulse oximeter. The investigator has confirmed the onset of anesthesia after lip tongue-numbing by probing the gingiva until there is no pain. Endo-ice has been used to assess the onset of pulp anesthesia.

NCT ID: NCT05727527 Completed - Local Anesthesia Clinical Trials

Effect of a Candy Flavoring Before Local Anesthesia on Anxiety and Pain Perception in Children

Start date: April 1, 2022
Phase: N/A
Study type: Interventional

This is a randomized clinical trial that aimed to test the effect of using sugar-free flavors as a sensory distraction technique during local anesthesia on pain perception when compared to a negative control group. Applying the flavor before injecting local anesthesia helped in distracting the child and reduced the associated pain.

NCT ID: NCT05166291 Completed - Local Anesthesia Clinical Trials

The Effect of Needle-free Injection System During Palatal Anesthesia

Start date: August 25, 2021
Phase: N/A
Study type: Interventional

Needle-free injection systems can contribute to the prevention of needle-related pain during palatal infiltration anesthesia (PIA) in children. Research with this topic on children is required.The purpose of this clinical study was to evaluate the effectiveness of the needle-free system versus traditional anesthesia on pain perception during PIA in children.The study was designed as a randomized, controlled cross-over clinical study with 48 children aged 6 to 12 years requiring dental treatment with PIA in bilateral maxillary primary molars. It has been revealed that the application of a needle-free system during PIA ensured a decrease in pain perception in children.

NCT ID: NCT04947267 Completed - LOCAL ANESTHESIA Clinical Trials

To Compare the Pulpal Oxygen Saturation Level After Administering Mepivacaine With and Without Vasoconstrictor

Start date: May 30, 2018
Phase: Phase 2
Study type: Interventional

As vasoconstrictors adversely affect pulpal hemodynamics, this study compared the pulpal oxygen saturation levels after employing inferior alveolar nerve block with 2% mepivacaine with 1:100,000 epinephrine (2% Scandonest Special) and 3% mepivacaine (3% Scandonest Plain).Two groups were made with 30 patients in each group. 2% mepivacaine with 1:100,000 epinephrine (2% Scandonest Special) was administered to the patients in Group A whereas 3% mepivacaine (3% Scandonest Plain) was administered to the patients in Group B. Rubber dam application, cavity preparation and composite filling was then done on the selected carious mandibular premolar. Pulpal oxygen saturation levels were recorded after administration of local anesthesia with Nellcor-550 pulse oximeter and Nellcor D-YS Multisite reusable sensor.

NCT ID: NCT04885777 Completed - Local Anesthesia Clinical Trials

Topical Lidocaine Anesthesia for Nasopharyngeal Sampling

Start date: September 1, 2020
Phase: N/A
Study type: Interventional

Introduction: Nasopharyngeal sampling is widely used in the diagnosis of the Coronavirus Disease 2019 (COVID-19). The aim of this study is to evaluate the effects of topical lidocaine application for nasopharyngeal sampling, on pain perception, the comfort of the patients, and the application difficulty for healthcare staff. Methods: This study is a prospective randomized placebo-controlled study conducted with 100 healthy volunteers (50 participants in Lidocaine group and 50 participants in Placebo group). Two ml of a solution containing 10 mg/ml of lidocaine was applied to each nostril of the participants in the Lidocaine group, and the same dose of 0.9% NaCl to the Placebo group. Investigators performed two repeated sampling one hour apart. The first sampling was performed before intervention, and the second was performed five-minutes after intervention. Investigators compared the changes in pain intensity and discomfort intensity using two numerical rating scales, the frequency of undesirable reactions, and the judgment of the practitioner staff about the sampling procedure between first and second sampling.

NCT ID: NCT04692883 Completed - Clinical trials for Postoperative Complications

Comparison of Functional Bracing vs Rigid Immobilization After Modified Percutaneous Achilles Tendon Repair

Start date: January 1, 2001
Phase: N/A
Study type: Interventional

Rationale There is ongoing controversy over the optimal treatment and rehabilitation strategy of an acute Achilles tendon rupture (ATR). The highest general complication rate is reported in patients treated with percutaneous repair and early mobilization. Objectives The purpose of the study is to compare the results of two ways of postoperative regimen after treatment with the modified and biomechanically significantly stronger percutaneous repair under local anesthesia. Methods & Population All the consecutive patients with an acute complete Achilles tendon rupture who will agree to take part in a study will be randomized after a modified percutaneous repair under local anesthesia into functional group (FG), using a modified brace and immobilization group (IG), wearing a rigid plaster, in both groups for the period of 6 weeks. After that they will follow the same (standardized) rehabilitation protocol. Major and minor complication rate, diameter of the healed tendon, active and passive ankle range of motion (using neutral zero method), standing heel-rise test (with 25 repetition within a minute for a grade of normal) and clinical outcome using American Foot and Ankle Society (AOFAS) hindfoot-ankle score, return to the previous activity level, presence of associated complaints and subjective assessment (scored as good, fair or poor) will be assessed. Time frame This will be a 4-year study with a 3-year follow-up. Expected outcomes: There will be no differences in demographic parameters (age, gender, side and mechanism of the injury) between groups. Patients in the FG will reach sooner final range of motion (ROM) and muscular strength without limping and will be (subjectively) more satisfied with the treatment. There will be no statistically significant differences observed between groups according to the number of complications and in the end functional results with return to pre-injury activities.
