Filter by:The goal of this observational study is to assess the laryngeal air column width difference measurement on point of care ultrasound as a predictive indicator of post-extubation stridor in the pediatric critical care population. The main question it claims to answer is: In pediatric intensive care unit patients, can point of care ultrasound measurements of laryngeal air column width difference be used as a sensitive and specific tool to predict post extubation stridor in comparison to standard qualitative and quantitative evaluations? Participants will be enrolled when they are on or approaching extubation readiness. At this time, an ultrasound of their airway will be performed by the investigators and the laryngeal air column width difference will be recorded.
Single Use Flexible bronchoscopes have gained popularity in recent years and are becoming technologically more advanced. They are widely accepted and used in everyday practice for simple procedures. The aim of this study is to evaluate single use flexible bronchoscopes in more advanced settings, such as interventional pulmonary procedures.
Endotracheal intubation can induce laryngotracheal injury which results in narrowing of the airway due to edema of the glottis. This can increase the risk of development of post-extubation stridor (PES)
All neonates, ages 0 to 4 months, presenting to LPCH pediatric ENT clinic for airway difficulties or stridor will be screened for inclusion. As is consistent with an acceptable standard of medical care, these children will undergo a flexible nasal endoscopic exam to make the diagnosis of laryngomalacia, as well as be weighed and a breastfeeding history taken. If laryngomalacia is present, the study staff with then administer the Infant Gastroesophageal Reflux Questionnaire (IGERQ) and an airway symptoms questionnaire (ASQ). Those babies with an IGERQ score of less than sixteen (no more than mild reflux) and an ASQ score greater than six will be eligible for randomization. The patient will then be randomly placed in the control group (placebo) or the intervention group (ranitidine 2mg/kg every 12 hours or famotidine 0.5 mg/kg daily). Patients will stay on medication for a minimum of 6 months, or until symptoms resolve. Patients will be seen in follow up at 1, 2, 3, 4, 5, 6, 8 and 10 months. At which time I-GERQ, ASQ and weights will be taken. The primary outcome measure will be the time for the ASQ score to drop to normal on ranitidine or famotidine versus placebo. A secondary outcome will be weight gain in percentile. If the patient's I-GERQ score goes above 16 at any time in the study, the patient will be crossed over to the treatment arm and started on medical treatment.
The purpose of this study is to evaluate the efficacy and adverse effect of nebulized corticosteroid to prevent post-extubation stridor in children.
Stridor is a respiratory noise caused by partial obstruction of the large airways at the level of the pharynx, larynx and/or trachea. The second most common cause of stridor is vocal cord paralysis. Awake nasolaryngoscopyn (ANL) is regarded as the gold standard for the diagnosis of laryngomalacia. However, ANL has some drawbacks as it may cause discomfort for the patient and the laryngeal view may be obscured due to patient movement or anatomical variations. Ultrasound (US) is a noninvasive, painless, radiation free, well tolerated imaging technique. Evaluation of the dynamic characteristics of the glottis by US revealed perfect reliability in comparison to nasolryngoscopy suggesting that US can be useful in the assessment of laryngeal adduction. The investigator hypothesize that laryngeal US can be an accurate and reliable adjunct in the diagnosis of functional and anatomical causes of stridor and dysphonia in the pediatric population.
The study aims to analyze and compare the clinical effects of using inhaled budesonide or intravenous dexamethasone in the treatment of postextubation stridor on children admitted to the pediatric intensive care units at Hospital Municipal do M´Boi Mirim and Hospital Albert Einstein.
The hypothesis of the study is that laryngeal US can accurately and reliably diagnose laryngomalacia in infants with congenital stridor. Stridor is a respiratory noise caused by partial obstruction of the large airways at the level of the pharynx, larynx and/or trachea. The most prevalent congenital cause of stridor is laryngomalacia. Flexible laryngobronchoscopy (FLB) under sedation is regarded as the gold standard. However, FLB under sedation has some drawbacks as it requires venous access, use of sedative agents, may cause discomfort for the patient and is costly. Ultrasound (US) is a noninvasive, painless, radiation free, well tolerated imaging technique. It allows for dynamic assessment of moving structures in an awake patient and the results can be easily displayed and recorded.
