10 Clinical Trials for Various Conditions
The purpose of the study is to achieve effective ventilation with critical intracuff pressure (Pcr) and determine if application of Pcr reduces the risks associated with over-insufflation of endotracheal cuff including postoperative sore throat, cough,nausea, vomiting, aspiration, and pneumonia.
Children and adults frequently need a 'breathing tube' when having anesthesia for surgery. The breathing tube is usually inserted after the anesthesia doctor puts a patient to sleep with medicine, so they do not feel the breathing tube. In children, there is often a leak of air between the tube and the windpipe, as the tube is not an exact fit. Anesthesia doctors usually listen for this leak around the tube by listening to the chest with a stethoscope while gently filling the lungs with oxygen from the anesthesia machine. The leak tells them if the tube is the correct size, or too small, or too tight. If it is too small, or too tight, they usually change the tube for a better fit. The purpose of this study is to see what happens to this leak in the 30 minutes after the tube is placed. No one really knows if the leak gets bigger, smaller, or stays the same. Knowing what happens to the leak will help anesthesia doctors to decide whether to change the breathing tube or not. This is important, as a tube that is too tight can lead to breathing difficulty after removing the tube at the end of surgery, and a tube that is too small may make it difficult for the breathing machine to work effectively for the patient as a result of a large leak of air or oxygen.
The purpose of this study is tp evaluate the changes in stress induced Urethral Leak Point Pressures (LPP) and other urodynamic measurements in response to acute pudendal nerve stimulation (PNS) in patients with a pre-existing implanted urological neurostimulator stimulating the pudendal nerve.
The primary objective is to investigate the pharmacokinetics (PK) of 2 doses of alfuzosin (given as a solution or tablets depending on age) in children and adolescents 2 to 16 years of age with elevated detrusor Leak Point Pressure (LPP) (≥40 cm H2O) of neuropathic etiology stratified into 2 age groups (2 to 7 years and 8 to 16 years). The secondary objectives are to investigate the safety and tolerability of the 2 dose regimens and to determine the effect of the 2 dose regimens on detrusor LPP.
The investigators have devised a simple method to continuously measure the CP using an invasive pressure monitoring setup (IPMS), which is used routinely in the operating room to monitor arterial or central venous pressures. The investigators have previously confirmed both in vitro and in vivo (previous IRB approved protocol), a clinically applicable agreement of the IPMS readings with the values obtained from a standard manometer (gold standard). In the current study, we will prospectively evaluate the relationship between the patient's head position and CP in patients undergoing otolaryngological surgery and also measure the oxygen concentration in the oropharynx to determine the potential risk of an airway fire.
We have devised a simple method to continuously measure the endotracheal tube cuff pressure (CP) using an invasive pressure monitoring setup (IPMS), which is used routinely in the operating room to monitor arterial or central venous pressures. We have previously confirmed both in vitro and in vivo (previous IRB approved protocol), a clinically applicable agreement of the IPMS readings with the values obtained from a standard manometer (gold standard). In the current study, we will prospectively evaluate the relationship between the patient's head position and CP in patients undergoing otolaryngological surgery. A secondary outcome measure is the oxygen or nitrous oxygen concentration in the oropharynx.
This is a prospective randomized cross over study of healthy volunteers undergoing continuous positive airway pressure ventilation via a noninvasive ventilation (NIV) mask with and without the addition of nasal cannulas. Mask leak will be measured by the ventilator after 60 seconds of spontaneous resting ventilation, with each subject serving as his or her own control.
In common clinical practice, one means of ensuring an acceptable cuff pressure in endotracheal tubes (ETT) is to hold continuous positive airway pressure (CPAP) of 20-25 cmH2O and inflate the cuff of the ETT until no gas leak is noted around the cuff. The purpose of this study is to validate this technique by checking the intracuff pressure using a manometer after the cuff is inflated using the CPAP technique.
Negative pressure wound therapy (NPWT) is widely used for chronic and acute wounds, severe burns, and post-operative care. Despite its benefits, the strong adhesive required to maintain an airtight seal increases the risk of medical adhesive-related skin injuries (MARSI), pain, and discomfort during removal. Global Biomedical Technologies (GBT) aims to develop an NPWT drape with "switchable adhesive" technology to enhance removal while maintaining an effective seal. This innovation is expected to benefit both single-use and serial-use NPWT applications by reducing MARSI and improving patient comfort. This project will compare the functionality and acceptability of Comfort Release® NPWT drapes with the industry-standard V.A.C. drape (KCI Technologies, Inc.) in a non-blinded randomized controlled trial. Specific Aims Aim 1: Compare Comfort Release® drapes with V.A.C. drapes in single-use NPWT applications in post-surgical patients (n=200) at Columbia University Medical Center and Weill Cornell Medical Center. Milestones: Demonstrate statistically significant (α=0.05) improvement over V.A.C. drapes in: Reduction of MARSI (Medical Adhesive-Related Skin Injury scoring system) Decreased pain (Indiana Polyclinic Combined Pain Scale) Reduced need for pain/anxiety medication Equivalent or improved seal effectiveness (leak incidence rate) Clinician acceptability Aim 2: Compare Comfort Release® drapes with V.A.C. drapes in serial-use NPWT applications in chronic wound patients (n=100) at Weill Cornell Medical Center. Patients will undergo three NPWT drape changes per week. Milestones: Demonstrate statistically significant (α=0.05) improvement over V.A.C. drapes in: Reduction of MARSI Decreased pain (Indiana Polyclinic Combined Pain Scale) Improved compliance with treatment duration Reduced need for pain/anxiety medication Equivalent or better seal effectiveness Clinician acceptability (questionnaire score \>4) Reduced nursing time by ≥20% Economic value through time and cost savings At each dressing change and final removal, qualitative data from clinicians will assess the acceptability and usability of Comfort Release® NPWT drapes.
The main questions the study aims to answer are: * How much do wounds improve when using the Avelle™ Negative Pressure Wound Therapy System for a maximum of 14 days? * How safe is the Avelle™ Negative Pressure Wound Therapy System?
