Filter by:The investigators designed this intervention to investigate the potential role of L-C in lipid and carbohydrates metabolism (primary outcome) with precision noninvasively measurement of: central blood pressure, pulse wave velocity and peripheral arterial stiffness (secondary outcome) in OSA patients.
To compare the effect of uvulopalatoplasty with no treatment in treating adult OSA.
This is a prospective study to see whether ultrasonography can predict difficult airway and/or predict obstructive sleep apnea syndrome (OSAS) in children.
There is a fundamental gap in the investigators ability to design effective surgical treatment of obstructive sleep apnea (OSA) for the 30-40% of patients who cannot tolerate non-surgical treatment. OSA surgery outcomes vary widely, with the chances of a successful outcome ranging from 5% to 65% for individual or combination procedures. To predict - and thereby to improve - outcomes, the investigators must determine what predicts surgical success. This project will compare findings from two evaluations: drug-induced sleep endoscopy (DISE) and upper airway magnetic resonance imaging (MRI). DISE has demonstrated important benefits, but it has important limitations. Upper airway MRI is the most complete evaluation performed during wakefulness, making it conducive to broad application and less expensive than DISE, but there are no studies utilizing MRI as a surgical evaluation. The investigators propose a cross-sectional analysis of 40 adult subjects with moderate to severe OSA. In addition to history, physical examination, and polysomnogram (sleep study), all subjects will undergo DISE and MRI to characterize the pattern of obstruction. The investigators will examine the association between DISE and MRI, focusing on specific DISE findings that have been associated with surgical outcomes. The investigators multidisciplinary team has substantial expertise and experience in OSA investigation, DISE, and upper airway MRI.
The purpose of the study is to determine if tonsillectomy eliminates symptoms of obstructive sleep apnea in patients with obstructive sleep apnea and marked tonsillar hypertrophy with normal soft palate and uvula length.
The study aims to evaluate the effect of non-supine positioning in the treatment of surgical patients with obstructive sleep apnea. The hypothesis is that non-supine positioning will result in a decrease in acute hypoxic events, defined as the number of apneas/hypopneas per hour of sleep.
The objective of this study is to determine if IV acetaminophen administered intraoperatively can decrease the dose of narcotics required for adequate pain control and shorten recovery time in the PACU specifically in obese patients at risk for obstructive sleep apnea.
Obstructive Sleep Apnea (OSA) is when a person stops breathing repeatedly during sleep. Breathing stops because the airway collapses and prevents air from getting into the lungs.This airway closure results in a decrease in the amount of oxygen that is in the blood. Anesthetics given during surgery are known to increase the tendency for a patient's airway to close immediately after surgery in the recovery room and to reduce the amount of oxygen in a patient's blood immediately after surgery. These two factors combined could have a profound effect on a patient's well being after surgery. Recent advances in general anesthesia, pain medications, and surgical techniques have made outpatient surgery more common. Due to the increase in outpatient surgeries, pain management techniques that will work efficiently and for longer periods of time are necessary. One of these techniques is a nerve block, which coats the nerve with a numbing medication and blocks all pain from that area. Nerve blocks are routinely used along with general anesthesia for outpatient surgeries and help reduce or eliminate the need for IV or oral pain medicine after the surgery. Nerve blocks can provide good pain relief with early recovery and fewer side effects (nausea, vomiting, etc.) related to narcotic pain medicines. Unfortunately, there are no studies that look at the effect of anesthesia and nerve blocks on breathing patterns and oxygen saturation levels after discharge from outpatient surgery. We therefore propose to study the changes in lung function tests and blood oxygen levels after a nerve block and general anesthesia for outpatient shoulder surgery. We would like to conduct a home sleep study including measuring oxygen levels while subjects are sleeping, before, during and after surgery, and test lung function both before and after surgery to see if there are any differences. We will recruit 10 subjects with eligibility based on clinically indicated shoulder surgery and a nerve block. The study will be non-interventional during surgery. It is possible that future screening for out-patient shoulder surgery includes preoperative overnight oxygen saturation measurement to identify patients at high-risk of changes in oxygen levels. These patients may benefit from hospital admission after surgery for close observation. Thus, this study could have significant implications for patient safety and resource utilization.
Patients with Congestive Heart Failure (CHF) on non-Intensive Care Unit medical services and/or visiting our outpatient Congestive Heart Failure Clinic will be screened using the STOP-BANG Scoring Model. (STOP-BANG stands for Snoring, Tiredness, Observed Apnea, Blood Pressure, Body Mass Index, Age, Neck Circumference, Gender.) Patients with high risk of Obstructive Sleep Apnea (OSA) will be referred for evaluation and treatment of Sleep Apnea. They will be followed to determine if treatment of Sleep Apnea improves their quality of life and decreases their utilization of the Hospital and Emergency Department (ED).
Enuresis (E) or bedwetting is a common pediatric complaint, and recent research has discovered a link with obstructive sleep apnea (OSA). In children, OSA is often secondary to enlargement of their adenoids or tonsils, and is often successfully treated with a steroid solution given through the nose. The relationship between SDB and E is incompletely understood. Airway obstruction affects the quality of sleep, as the child will wake as the oxygen levels drop. Abnormal sleep also can decrease the secretion of hormones that affects the kidney's ability to concentrate urine at night, which can result in too much urine in the bladder. Contemporary evidence also suggests that patients with enuresis have abnormal sleep phases, which may impair the communications and inhibition of the bladder. In previous studies, the investigators have demonstrated that children with E have a high likelihood of having concomitant SDB. The investigators have also demonstrated that children with E and symptoms of SDB do not respond to typical management for bedwetting. Therefore, the investigators propose to treat patients presenting with E with our standard treatments for E (bed alarm) and first line therapy for SDB: Intranasal steroids. This medication helps to decrease the inflammation of the adenoids and tonsils, thereby reducing the airway obstruction. the investigators hypothesize that children with significant symptoms of SDB will improve with the addition of INS, and the investigators hope to see an improvement in their bedwetting, quality of life, and sleep quality as well. To test this, patents with E will be recruited from the pediatric urology clinic. They will be offered the standard treatment for E, the bed alarm, and the treatment group will be given an intranasal steroid spray. The investigators will then reassess the patients 3 months after treatment, and compare the two groups.
