Carbon monoxide (CO) is a colorless and odorless gas that can enter the human body through environmental exposure and especially tobacco use. CO binds to hemoglobin with a much higher affinity than oxygen, thereby reducing oxygen transport to tissues. This condition may lead to various physiological and psychological effects, particularly on the nervous system. In the literature, CO exposure has mainly been investigated in the context of acute poisoning cases and smoking-related effects. However, studies evaluating the effects of low-level and chronic CO exposure-more commonly encountered in the general population-on pain perception, sensory functions, and psychological status are limited. Tobacco smoke is an important source of CO, and exhaled CO levels have been shown to be significantly higher in smokers and associated with various neurocognitive changes. Evidence suggests that CO exposure may influence anxiety, depression, attention, and cognitive functions. In addition, some studies indicate that CO may affect brain regions involved in pain perception and emotional regulation. However, there is insufficient research examining the relationship between low-level carbon monoxide exposure and pain threshold, sensory functions, anxiety, depression, and subjective health complaints within the same study framework. This study aims to evaluate the relationship between exhaled carbon monoxide (CO) levels and pain threshold, sensory functions, anxiety, depression, and subjective health complaints in healthy adults. By examining the multidimensional effects of low-level CO exposure, the study seeks to fill an important gap in the literature and provide a more comprehensive understanding of this issue.

A significant proportion of patients hospitalized in intensive care units (ICUs) require mechanical ventilation, and the treatments applied during this process may cause pain. Pain is defined as an unpleasant sensory and emotional experience associated with actual or potential tissue damage. Although it is associated with delirium and agitation, pain is often an overlooked symptom in ICU patients, and a large proportion of mechanically ventilated patients continue to experience moderate to severe pain. The most common type of pain in critically ill patients is nociceptive pain, which may result from invasive procedures such as tracheal intubation, catheter insertion, aspiration, wound care, and patient repositioning. Additionally, the noisy and unfamiliar ICU environment and patients' inability to express themselves may further increase the perception of pain. Regular assessment of pain is associated with many positive outcomes, including more effective pain management, appropriate use of analgesic and sedative medications, and shorter duration of mechanical ventilation and ICU stay. Although self-reporting of pain is considered the gold standard, many patients receiving mechanical ventilation are unable to communicate their pain. Therefore, various behavioral pain assessment scales are used to evaluate pain in ICU patients. One of these tools is the Behavioral Indicators of Pain Scale (Escala de Conductas Indicadoras de Dolor - ESCID), which was developed to assess pain in critically ill adult patients receiving mechanical ventilation who are unable to communicate. However, a Turkish version of this scale has not yet been developed. Therefore, the aim of this study is to translate the ESCID scale into Turkish, perform its cultural adaptation, and test the validity and reliability of the Turkish version.
NCT07351383
This clinical study tested and compared two ways (cold-base technique or "cryoanesthesia" and conventional benzocaine gel) to reduce pain from dental injections in children. Researchers worked with 28 children between 6 and 12 years old who needed injections on both sides of the lower jaw for dental treatment. Each child received cryoanesthesia on one side and 20% benzocaine gel on the other side, in different appointments, and the team measured pain, behavior, heart rate, and blood oxygen levels.

A Spilt Mouth Clinical Comparative Evaluation Of The Electronic Anesthetic Efficacy Comparison of traditional local anesthesia with electronic local anesthesia in terms of the ability to reduce pain during injection and the duration of the anesthetic effect
NCT07252648
This study aims to find out whether listening to music before, during, and after pain procedures can help reduce anxiety, pain catastrophising, and acute pain in patients with chronic pain. Music therapy may provide a simple, safe, and non-drug way to help patients relax and feel more comfortable. In this study, adult patients with chronic pain who are scheduled for interventional pain procedures at Singapore General Hospital will be randomly assigned to one of two groups. One group will listen to self-selected music through headphones and speakers before, during, and after the procedure. The other group will receive standard care without music. Researchers will measure anxiety, pain catastrophising, and pain levels before and after the procedure using validated questionnaires. The main outcome will be the level of anxiety after the procedure. Other outcomes include pain catastrophising scores, pain scores during local anaesthetic injection, and overall patient satisfaction. This study will help determine if music therapy can be routinely used to improve comfort and emotional well-being for patients undergoing interventional pain procedures.

Brief Summary of the Study This study investigates the effects of locally administered vitamins C and E on orthodontic tooth movement during the initial stage of treatment. Orthodontic tooth movement relies on bone remodeling, which can be influenced by antioxidants like vitamins C and E. Vitamin C promotes collagen formation and osteoblast activity, while vitamin E has anti-inflammatory and antioxidant properties that may impact bone metabolism. The study is a randomized clinical trial conducted in multiple clinics, where patients will be divided into three groups: 1. Control group - receives a saline injection. 2. Vitamin C group - receives a local injection of vitamin C. 3. Vitamin E group - receives a local injection of vitamin E. Injections will be administered every two weeks for six months, while patients undergo orthodontic treatment with fixed appliances. Researchers will evaluate the rate of tooth movement, root resorption, pain perception, and patient experience. Additionally, biomarkers related to bone remodeling will be measured in gingival crevicular fluid at different time points. The study aims to determine whether local administration of vitamins C or E enhances orthodontic tooth movement and elevate their effects on the orthodontic potential side effects like root resorption and pain. The findings may provide valuable insights into optimizing orthodontic treatment with the help of antioxidants.
NCT06841601
Local anesthesia is an anxiety-provoking procedure. Pain control is important for effective behavior guidance, specially among pediatric patients. This study aims to evaluate the effectiveness of Buzzy® as a topical anesthetic in pain perception through two ways: once using vibration mode without the cold pack and the other using the cold pack without vibration and comparing it to topical anesthetic gel during different anesthetic techniques Methods: A randomized controlled clinical trial involving 72 healthy cooperative patients aged 5-9 years. They will be allocated to receive local anesthesia either using the vibration mode of Buzzy Bee (test group) or the cold pack of Buzzy Bee (test group) or conventional topical anesthetic gel (control group). Pain response will be assessed using Visual Analog Scale (VAS) and SEM scale.
NCT06659731
This study aims at assess sensory perception, and pain perception, in neurodivergent children and adolescent in the autism spectrum. To achieve this goal, the quantitive sensory testing (QST), a controlled and replicable protocol, will be used, to assess perception in different sensory modalities: heat sensations, mechanical detection threshold and pain threshold. As secondary aim, the cortical processing of thermal painful stimuli will be collected through electroencephalography (EEG) in order to investigate if there are differences in the cortical processing of painful stimuli between clinical sample and control sample, and if it could be associated with differences in the subjective experience between the two groups. Finally, it will be explored the association between such differences, and indexes of psychopathology and dispositional measures.
NCT05192902
This single-blind two-arm randomized control trial (RCT) aims to evaluate the pain perception during and following administration of dental local anaesthesia using two different systems; i.e. computer-controlled (CCLA) and conventional.

Electromyography (EMG) is a useful test for diagnosis and monitoring of lower motor neuron disorders. It is mostly done in conjunction with a Nerve Conduction Study (NCS). Like other invasive medical procedures; electrodiagnostic tests have been known to cause iatrogenic pain for the patient, the intensity of which varies from person to person. Multiple modifiable as well as non-modifiable risk factors associated with EMG pain have been described in literature.Various approaches targeting different mechanisms of pain perception have been tested to make this procedure comfortable for the patients. These approaches range from simple distraction techniques to the use of topical and oral analgesics.Most of these studies have looked at adult population which has, supposedly, better pain tolerance as compared to children. Data on EMG associated pain in pediatric population is scant. This trial will assess the effect of combined oral and topical analgesics to reduce pain perception during NCS and EMG tests in the pediatric population.
NCT05731401
The aims of this study are to explore what beliefs children and adolescents manifest about the cause of the pain they describe; to compare whether if there are differences between beliefs by age and by persistence of pain; and to relate explanations of the cause of pain with current scientific evidence to determine if these beliefs are erroneous.
NCT05480839
The focus of this study is to assess the differences in patient perceptions of pain undergoing cataract surgery by using the Refractive Laser-Assisted Cataract Surgery (ReLACS) technique compared to the standard Manual Cataract Surgery (MCS) technique using an immediately sequential bilateral approach. This study also aims to further explore difference in patients' perceptions of pain depending on timing of neurolept anesthesia in the ReLACS technique. The importance of this study is appreciated patient perception of pain during ReLACS, which is an emerging technique for cataract surgery and has been sparsely reported on to date. This investigation will include the analysis of various surgical, ocular, medical, and psychosocial metrics of patients undergoing both ReLACS and MCS at Uptown Eye specialist.
NCT03777137
This is a single institution, single-blinded, long-term exploratory study using participant as his/her own control to evaluate and compare the potential analgesic effect on experimental heat pain of Transcutaneous Magnetic Stimulation (TMS). TMS will be delivered by a commercially available device (Rapid2, Magstim Corp) at three different cortical target sites and one sham target site in healthy participants 18-88 years of age. The quantitative evaluation measure is the change in the painful heat threshold Quantitative Sensory Testing (QST) of thresholds for cutaneous heat stimuli before and after TMS.
NCT02991014
This study aims to compare the impact of listening to frequency-modulated music vs. non-modulated music (both researcher-selected), and to test whether there are differential effects on pain and stress perception. Further, these two conditions will be compared to a third condition, in which participants will be exposed to self-selected non-modulated music. It is hypothesized that both researcher-selected frequency-modulated music and self-selected non-modulated music result in stronger decreases in stress and pain compared to researcher-selected non-modulated music, while it is expected that there will be no differences in researcher-selected frequency-modulated music and self-selected non-modulated music. The intervention consists of ten sessions of music listening in the course of three consecutive weeks.
NCT04623229
The focus of this study is to assess how pain can be mitigated for patients undergoing cataract surgery through the early application of anesthesia prior to the surgery as compared to the standard timing, and by using the ReLACS cataract surgery technique compared to the standard MCS technique.
