Filter by:Post-operative pulmonary complications (PPCs) have a major impact on patients and healthcare expenses. The goal of perioperative respiratory therapy is to improve airway clearance, increase lung volume, and mitigate atelectasis. Incentive spirometers (IS) are ubiquitously used to prevent atelectasis and PPCs—implementation of which requires substantial provider time and healthcare expenses. However, meta-analyses have demonstrated that the effectiveness of ISs is unclear due to poor patient compliance in past studies. The goal of this investigation is evaluate the effectiveness of IS on post-operative clinical outcomes. The aims of this investigation are to evaluate 1) if IS use compliance can be improved by adding a use-recording patient reminder alarm, and 2) the clinical outcomes of the more compliant IS users vs. the less-compliant IS users.
Controlled hypotension is a preferred method for reducing surgical bleeding during septoplasty operations however, the level of hypotension and bradycardia should not disrupt cerebral oxygenation. On this account, the investigators aim to investigate the effects of different volatile anesthetics combined with a short-acting opioid on cerebral oxygenation during controlled hypotension using near infrared spectroscopy.
Hypoxemia may contribute increased morbidity and mortality in chronic obstructive pulmonary disease (COPD) patients. We aim to characterize the role of acute and chronic hypoxemia for vascular function. For this purpose we measure capillary oxygen concentration and vascular. Vascular function is assessed by flow-mediated dilation oft he brachial artery, forearm blood flow and laser doppler perfusion imaging. We hypothesize that hypoxemia leads to impaired vascular function.
Objective: Objective of this pilot feasibility study is to monitor crSO2 using NIRS INVOS 5100 (Somanetics, USA) in addition to SpO2 monitoring to guide supplemental oxygen delivery and respiratory support based on both measurements in preterm neonates during the first 15 minutes after birth. Patients: Preterm neonates <34+0 weeks of gestation born via caesarean section and/or who require respiratory support will be eligible for the study. Design: A prospective two-centre randomized controlled pilot feasibility study Methods: Study group: Pulse oximetry will be used to measure SpO2 and heart rate as routine non-invasive monitoring in the first minutes of resuscitation. In addition during the first 15 minutes NIRS measurements will be recorded. crSO2 measurements in addition SpO2 measurements will be used to guide supplemental oxygen support and respiratory support during the first 15 minutes after birth. Control group: Only SpO2 measurements will be used to guide supplemental oxygen support and respiratory support during the first 15 minutes after birth. Hypothesis: Supplemental oxygen support and respiratory support guided by crSO2 and SpO2 measurements will reduce the time in % minutes of crSO2 <10th or >90th centile in preterm neonates during the first 15 minutes after birth Outcome Parameter: Primary outcome parameter will be duration in % minute of crSO2 <10th or >90th centile.
