Filter by:The purpose of this study is to evaluate the breathing patterns of women who undergo cesarean delivery with spinal or epidural morphine for post-operative pain control in the first day after surgery. Some women who undergo cesarean delivery may be at risk for respiratory complications related to opiate administration for post-operative pain. The primary aim of this study is to evaluate post-operative minute ventilation in women who undergo cesarean delivery using a novel method of non-invasive minute ventilation monitoring, and to see if there are predictive risk factors that may predispose women to post-operative hypoventilation.
This is an investigator led, randomised, double blind, placebo controlled, double arm comparator study.
PRODIGY is a prospective, multi-center, post-market, international cohort study. The primary objective of this study is to derive a score to identify subjects at risk to have respiratory depression (RD) episodes in patients undergoing opioid therapy in the hospital ward and monitored by capnography. The score will be derived by using subjects within the derivation cohort and internally validated using subjects within the validation cohort. The primary endpoint used to derive the score will be the occurrence of RD episodes derived by Capnostream 20p device memory data combined with clinical data and validated by an independent Clinical Endpoint Committee (CEC) during the study course.
Multi-center observational trial with study device blinded in order to assess in parallel standard monitoring and intervention practices related to management of respiratory compromise in the post-anaesthesia care unit (PACU)
The standard anesthetic care plan for people having adolescent idiopathic scoliosis surgery will be accompanied by a pharmacokinetic simulation of the administered drugs to suggest opportunities to adjust drug doses to achieve tolerable pain control after surgery, avoid respiratory depression and allow patients to respond quickly either during intraoperative testing or at the conclusion of surgery.
Purpose of the Study: (1) To classify an individual subject's ventilatory response in terms of respiratory depression to a bolus of remifentanil under normoxic and hyperoxic conditions. (2) Measurement of specific respiratory parameters to predict the opioid-induced respiratory depression (OIRD) response.
Respiratory depression occurs in labor and delivery; noticeably when neuraxial opioids are given.Pathophysiological respiratory depression -failure to respond to hypercapnia or hypoxia - is challenging to measure clinically.American Society of Anesthesiologist guidelines recommend suitable respiratory monitoring for 24 hours post cesarean delivery (CD). Use of capnograph will enable us to assess breath-by-breathe respiration in a population receiving neuraxial opioids - potentially at risk for respiratory depression. Our aim is to assess our ability to capture maternal postpartum respiratory parameters in a cohort following opioid neuraxial administration for CD.
The U.S. Environmental Protection Agency has traditionally examined the effects of single pollutant exposure on human health outcomes; however, to provide a better assessment of pollutant exposure-associated effect on human health the Agency is moving toward a multi-pollutant approach. Ozone (O3) and nitrogen dioxide (NO2) are national ambient air quality standards (NAAQS) criteria pollutants that are major constituents of ambient air pollution. This study will address the Agency's goals by investigating the cardiopulmonary health effects of sequential exposure to O3 and NO2 in healthy adult human volunteers. The findings of this study will provide data that will inform risk assessment models for O3 and NO2 exposures. Additionally, the findings will provide insight into how the human health effects of multi-pollutant exposures differ from those of single pollutant exposures.
Impairment of airway patency is a common cause of extubation failure and opioids and hypnotics can adversely affect airway patency. Ketamine, a noncompetitive antagonist of N-methyl-D-aspartate (NMDA), unlike other anesthetics activates respiratory effort and promotes bronchodilation. At subanesthetic plasma concentration, ketamine reduces both opioid and propofol requirements. The purpose of this pharmaco-physiological interaction trial is to evaluate the effects of ketamine on breathing and electroencephalography in mechanically ventilated patients.
The US EPA Clean Air Multiyear research program is moving toward a multi-pollutant approach to the assessment of air pollution in response to recommendations by the NRC 2004 and the BOSC in 2005. Such an approach better reflects the complexity of real-world air pollution problems and parallels evolving scientific and regulatory considerations. Ozone (O3) and diesel exhaust (DE) generally are major and important components of ambient air pollution. This proposed study will address the agency's goals by investigating the cardiopulmonary health effects in healthy human subjects co-exposed to O3 and DE. The findings derived from these exposures will provide NCEA findings for risk assessments of O3 and DE, as well as the Office of Air and Radiation (includes OTAQ and OAQPS) with information relevant to possible modulation of PM-induced health effects and responses by a gaseous co-pollutant for potential standard setting. Additionally the findings will address the fundamental driving principle of the Clean Air Research strategy related to reduction of health due to air pollutant exposures.
