Filter by:This study seeks to explore whether heart rate variability (HRV) biofeedback can be effective in the treatment of chronic cough. Chronic cough has many causes, including asthma, postnasal drip, and gastroesophageal reflux disease (GERD), each with a specific treatment. However, among a subset of cough patients, no clear cause is found despite extensive workup, and traditional treatment methods do not provide relief. Several studies revealed less common causes of chronic cough and disordered breathing such as vagal neuropathy, paradoxical vocal fold motion, and stress. Additional research identified links between the neurological networks that produce the cough reflex and those that maintain normal breathing. HRV biofeedback is a self-regulation technique that uses computer equipment to monitor heart rate and breathing, two key functions of the autonomic nervous system. By using this non-invasive behavioral technique, cough patients can regulate their breathing and autonomic function, potentially leading to improved autonomic balance and a reduction in cough symptoms.
The intent of this study is to see how boys and girls aged 1-5 and coughing since 1-2 days due to common cold respond to a specific protective cough syrup taken before going to bed for one night, with respect to a similar but not specific syrup (placebo). The symptoms evaluated include especially cough frequency but also cough intensity, bother, and sleep quality of the child and parents.
Chronic cough is an important clinical problem in primary care and sub-specialty practice. Besides the distress experienced by patients with chronic cough, significant healthcare resources are expended to understand the role of gastroesophageal reflux, asthma and post-nasal drip in understanding their contribution to cough. Obstructive sleep apnea (OSA) is common in patients with chronic cough. More importantly, treatment of OSA with continuous positive airway pressure (CPAP) has led to improvement in cough for chronic cough patients. Mechanisms by which OSA therapy with CPAP can improve cough includes beneficial effects on reflux and airway inflammation. The aim of this study is to definitively establish that CPAP therapy for treatment of OSA in chronic cough patients improves cough. While these patients with chronic cough are not routinely screened and treated for OSA, this study aims to evaluate these chronic cough patients with screening questionnaires for OSA and if necessary with polysomnography and randomize them to either CPAP or sham CPAP for 6 weeks.
To develop and validate a library of cough spectrum from a target of 1000 cough acoustics. Coughs arising from upper respiratory infection, lower chest infections, asthma, allergic conditions are included in the study. Cough acoustic in absence of respiratory disease is also included. This is a prospective observation cohort study recruiting children below the age of 16 years old in 2 arms : (1) Patients with respiratory conditions presenting with cough and (2) Well patients without active coughing.
The Pilot of Zinc Acetate to Improve Chronic Cough (ZICO) is a study of 36 patients with chronic refractory cough that will be used to (1) assess if zinc acetate (150 mg/day) will improve patient reported measures of cough, (2) to establish if treatment with zinc acetate is well tolerated, and (3) to determine if the trial logistics are feasible.
Pain, cough, hypertension and tachycardia are frequent events during extubation due to a secondary stimulation of mechanoreceptors located in the airway. The mechanical effect of the endotracheal tube activates autonomic reflexes, a situation that could potentially impair the clinical condition of patients. Previous studies have used remifentanil during emergence and extubation showing good results to control this reflex response. However, it is unknown so far, the optimal effect site concentration (Ce) of remifentanil to allow a better control of these events with a low incidence of adverse effects after have received inhaled anesthesia plus remifentanil for anesthetic maintenance. This study will determine the Ce of remifentanil associated with a lower proportion of cough and hyperdynamic circulatory response during extubation for emergency after exposure to sevoflurane or desflurane.
This study seeks to identify ways to help parents safely use cough/cold medications with their children. The study focuses on 3 key tasks that have been found to be difficult for parents: 1) decision-making about whether medicines should be given based on a child's age, 2) use of active ingredient information to determine which medications are safe to give together, and 3) medication dosing. Specific ways that labels and dosing tools can be changed to improve parent understanding and ability to use pediatric cough and cold medications will be tested. This includes looking at whether including age restriction information on the front panel helps parents make better decisions about whether a medication should be given to a child, as well as whether presence of a specific warning or pictogram can help improve this understanding. In addition, the role of font size, including a box around ingredients, and use of a specific warning to look at and compare active ingredients, will be examined to see if these can help parents decide if two medications can be given together safely. Finally, dosing charts with pictograms of dosing tools, and provision of certain dosing tools, can lead to fewer parent dosing errors. A label/dosing tool combination that incorporates what is learned from the first part of the study will be developed based on findings from the first part of the study, and then tested to see whether this improves parent understanding and use of pediatric cough and cold medicines. Hypotheses include: 1) changes in labels and dosing tools, such as including explicit warnings, and pictographic warnings/instructions can improve parent understanding and ability to act on of medication instructions, 2) parents with low health literacy and/or LEP will especially benefit from strategies such as explicit wording, warnings, and pictogram, and 3) parents receiving the comprehensive labeling and dosing strategy will have a better understanding of appropriate use of cough/cold medications, including fewer dosing errors, compared to standard labels. A multi-part experiment will be conducted. Findings will be merged with known evidence around health literacy best practices to develop a comprehensive, consumer-centered strategy for English and Spanish-speaking parents. Pilot testing of the comprehensive strategy in comparison to existing labels will then take place.
The investigators aimed to investigate the effects of pretreatment with different doses of dexmedetomidine on the cough caused by fentanyl during anesthetic induction. Patients undergoing elective surgeries under general anesthesia will be randomly allocated to 4 groups (n = 60, each group). Dexmedetomidine 0, 0.03, 0.06, and 0.09 μg/kg/min will be pump-administered in 10 mins to groups I, II, III, and IV, respectively, followed by the induction of general anesthesia with intravenous fentanyl 4 μg/kg. The incidences and severity of cough that occurred within 2 min after the injection of fentanyl will be recorded, and the incidences of cardiovascular adverse events that occurred between the administration of the dexmedetomidine infusion and 2 min after tracheal intubation will be recorded.
The objectives of this study are to determine the sensory-mechanical responses to Eucapneic Voluntary Hyperventilation (EVH) and Mannitol in individuals with cough variant asthma (CVA) and methacholine-induced cough with normal airway sensitivity (COUGH) and compare these responses to a control group of healthy individuals without asthma or chronic cough. We hypothesize: 1. EVH and Mannitol cause dyspnea, cough, small airway obstruction with resultant dynamic hyperinflation, gas trapping and autoPEEP in individuals with CVA and COUGH, but not healthy controls. 2. The sensory-mechanical responses to both hyperosmolar challenges (EVH and Mannitol) are comparable within groups (CVA, COUGH and healthy controls).
Cervical cancer is the third most common genital cancer worldwide. The diagnosis of cervical cancer is performed with the cervical biopsy which is guided by the colposcopy. The colposcopy guided cervical biopsy creates pain and several methods have been reported to overcome the pain related with this procedure. Local anesthetic agent injection into the cervix has been studied and found to be effective and also, forced coughing was compared with local anesthetic injection and it is found to be more effective. In fact local injections can create the pain by itself.However no study compared the effect of forced coughing to local anesthetic spray. The study aims to evaluate the comparison of forced coughing with local anesthetic spray with respect to perceived pain during colposcopy guided biopsy.
