Filter by:The purpose of this study is to use computers to simulate airflow in 3D construction of your nasal cavity generated from cone beam CT images. The results from computer simulations will help researchers identify the severity of cleft-induced nasal dysfunction and assess the impact of current treatment in restoring breathing function. The ultimate goal is to improve post-surgery outcomes to restore nasal breathing function to normal levels.
Patients suffering from pathology of posterior eye chamber such as diabetic retinopathy, retinal detachment, traumatic eye injury, retained lens fragments, macular hole, pucker, dislocated intraocular lens after cataract surgery or vitreomacular traction are often subjected to pars plana vitrectomy (PPV). PPV is minimally invasive endo-microscopic operation usually performed in topical anesthesia combined with sub-Tenon or retrobulbar block done by surgeon, supplemented by intravenous analgo-sedation given by anesthesiologist. Continuous infusion and dose adjustment of intravenous anesthetics applied should procure moderate sedation and preservation of patients' spontaneous ventilation. However, despite carefully applied anesthetics and standard low-flow nasal oxygenation (LFNO) (5 L/min O2 via nasal catheter), inadequate spontaneous breathing can occur leading to low blood oxygen level (hypoxia). Obese patients are susceptible to hypoxia and hypercapnia (high CO2 blood level) during analgo-sedation. Respiratory instability of obese patients is often associated to their subsequent circulatory instability (heart rate and blood pressure disorders). On the other hand, high-flow nasal oxygenation (HFNO) is usually used during anesthesia induction when difficult maintenance of airway patency is expected, in intensive care units during weaning patients from mechanical respirator and in postanesthesia care units during awakening from anesthesia. It can deliver 20 to 70 L/min, up to 100% inspiratory fraction of O2 (FiO2) to patient. High oxygen/air flow produces 3-7 cmH2O of continuous pressure in patients' upper airways therefore providing better oxygenation. Oxygen/air mixture delivered by HFNO is humidified and heated, thus more comfortable to patient than dry and cold LFNO. Aim of this study is to compare effect of HFNO to LFNO during intravenously applied standardized analgo-sedation given for PPV in obese adult patients. Investigators hypothesize that obese patients, whose breathing pattern is preserved, receiving HFNO vs. LFNO during standardized analgo-sedation for PPV will be more respiratory and circulatory stable, preserving normal blood O2 and CO2 level, breathing pattern, heart rate and blood pressure.
A prospective observational cohort study that measures pre- and postoperative outcome of septorhinoplasty by means of patient-related outcome measures (PROMS: NOSE, FACE-Q, Utrecht Questionnaire, SCHNOS and BDDQ-AS) as well as with functional tests (NAR, AR, PNIF).
The specific aim of this study is to determine whether pre-operative treatment with a bupivacaine nerve block can influence post-operative pain and oxycodone usage among rhinoplasty patients. Specifically, we plan to directly compare the reported pain scale, nausea, and oxycodone usage among patients who received the bupivacaine block against those of patients in the saline control condition. These assessments will be documented on day 0 (day of operation) by a nurse in the Post-Anesthesia Care Unit, while the same data points will be collected over the phone by our clinical research coordinator on post-operative days 1, 2 , 3, and 8 following discharge.
The mainstay of treatment in viral upper and lower respiratory tract disease is airway clearance. Viral respiratory tract infections account for a substantial amount of emergency department (ED) visits, financial and stress burden on caregivers. In addition, they also account for a large number of ED return visits. While airway clearance is considered a mainstay of treatment the pragmatic effectiveness of various devices remain unstudied in patients who are discharged from the ED. The objectives of this study are to compare the pragmatic effectiveness of two commonly used suction devices the NoseFrida and bulb suction and to provide a descriptive analysis on 72 hour return to ED rates and readmission rates. Patients will be enrolled October 15, 2018 to October 15, 2019 or until NoseFrida supplies are depleted. Fridababy will supply 500 NoseFrida devices and replacement filters. Patients aged 1 day to 24 months presenting Vanderbilt Childrens ED with symptoms of nasal congestion or bronchiolitis who require suctioning and will be discharged from the ED will be approached for enrollment. Exclusion criteria include no upper airway abnormalities or previously enrolled in study. The study design is a prospective and retrospective observational study. We anticipate about 500 patients to be enrolled in this study. Families will then be approached for consent to participate. Caregiver will fill out a data collection form then be instructed on how to use the NoseFrida. Next, family with trial it on their child while in the ED. Caregivers will then fill out a 7 point Likert survey on both the bulb suction and NoseFrida device. The family will go home with this device and a set of replacement filters and instructed to suction their child as needed. The primary investigator (PI) will then complete a 72 hour chart review to determine the number of return to ED visits and readmission rates. To compare ED returns with retrospective data, KSP will conduct a review of the business objects database using ICD9 codes specific for viral respiratory tract infections over the past 3 years to determine a control return ED visit rate. Data will be compared using a paired T-test. If data is not normally distributed we will use a Wilcoxon signed-rank test. We will also use a multivariable logistic model to examine associations adjusted for age and illness severity.
The research team has developed a prototype for an investigational mechanical nasal dilator and the investigators aim to evaluate its efficacy. Specifically, the investigators wish to address the following research questions: 1) How does mechanical nasal obstruction affect patients' lives? The investigators aim to answer this question with use of validated questionnaires. 2) How do currently available mechanical nasal dilators affect objective and subjective findings related to nasal obstruction? This will be evaluated with objective nasal airflow testing and with modifications to validated questionnaires 3) How does the investigational team's novel device affect these same outcome measures? 4) Do patients find the investigational device subjectively comfortable and efficient?
Adenotomy, together with tonsillectomy, belongs among the most frequently performed surgical procedures in paediatric patients. These surgical procedures are associated with the second highest incidence of post-operative nausea and vomiting (PONV) (following strabism correction surgery) in paediatric surgery. PONV is associated, apart from the discomfort for the child, with a number of complications: dehydration, metabolic disruption or danger of haemorrhage and aspiration of the gastric content. Adenotomy is a typologically completely different surgical procedure, with a different target structure of the surgery, and the length and invasiveness of the procedure. Thus, it is possible to expect a difference in PONV incidence when compared to tonsillectomy. Adenotomy is a surgical procedure performed namely in children of the pre-school age. This is associated, among others, also with the problem of objectivization of post-operative nausea, which is very difficult to verbalize in small children, being a subjective feeling of body discomfort. It is possible to expect that the overall incidence of PONV will be significantly underestimated.
Nasal obstruction is a very subjective sensation but it's also a frequent reason of consultation. Two specific questionnaire NOSE and RhinoQOL were validated; but rhinomanometry value is still a question to debate. As well as the difference between acoustic rhinometry and rhinomanometry. Usually nasal obstruction due to a septal deviation is treated by septoplasty. If the anatomic result can be proved true, the patient's felt would be unsuccessful. The aim of this study is to assess the impact of septoplasty on the nasal obstruction, objectively by rhinometry and subjectively by questionnaire.
Evaluation of long-term (5-year) quality of life after nasal airway obstruction treatment with the Aerin Vivaer Stylus
Currently, there are no tools that can measure nasal airflow in an objective manner that is non-invasive to the patient. This clinical study aims to address this by evaluating the use of thermal imaging as a diagnostic tool for measuring nasal airflow. Proper airflow cools the nasal airway as it passes--obstructions or narrowed airways hinder flow and results in elevated temperatures along the airway and nasal tissue. It is this elevation in temperature, or more specifically, loss of cooling, that we hypothesize to be measurable with thermal imaging. Participants in this study will be asked to perform 3-4 nasal breathing cycles which will be recorded by the thermal imager.
