Filter by:Scrotal, urologic surgery has traditionally been conducted in the hospital setting, typically with the use of sedation, spinal anesthesia or general anesthesia. There has been a recent push to move certain scrotal urologic surgeries out of the hospital operating room into a ambulatory, outpatient basis with recent literature demonstrating this in many centers. The use of local anesthesia alone poses numerous benefits. The investigators wish to compare patients who are undergoing invasive scrotal surgery under local anesthetic to those who additionally have a topical anesthetic cream (EMLA) applied to the scrotum to determine if this further increases patient tolerability of these procedures.
This study was conducted to a Comparison of Pain Perception for Nerve Block and Infiltration Injection Using the Conventional Method and Two Computerized Control Systems.
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).
The goal of this clinical trial is to evaluate if caudal dexmedetomidine can provide effective analgesia during inguinoscrotal surgeries in pediatrics, if used caudally alone (and not as an adjunct to caudal bupivacaine). The main question it aims to answer is: - Can caudal dexmedetomidine provide effective analgesia? Participants will be pediatrics aged from 1 to 6 years ASA-I and ASA-II undergoing inguinoscrotal surgeries. - A total of 50 pediatric patients who will undergo inguinoscrotal surgery will be allocated randomly into 2 equal groups: - Group B (n =25): In this group, and after induction of general anesthesia, pediatric patients will receive a caudal injection of bupivacaine 0.125 % in a dose of 1ml/kg. - Group D (n =25): In this group, and after injection of general anesthesia, pediatric patients will receive a caudal injection of dexmedetomidine in a dose of 1.5 mcg/kg.
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.
This is a randomized clinical trial that aims to test the effect of using sugar-free flavors as a sensory distraction technique during local anesthesia on pain perception and anxiety when compared to negative control group. We expect that using the flavor before injecting local anesthesia will distract the child and reduce pain and anxiety.
This study will test the effectiveness of addition of Sodium Bicarbonate as a buffering agent to the anaesthetic solution on minimizing the pain of injection and increasing the onset time and potency of the anaesthetic solution in children
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.
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.
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.
