Can Continuous Non-invasive Monitoring Improve Stability of Intraoperative Blood Pressure - A Feasibility...
Hip FracturesHypotension on Induction5 moreBackground During anaesthesia for repair of a broken hip, many patients experience low blood pressure. There have been many studies showing that patients who experience low blood pressure during anaesthesia are at increased risk of sustaining kidney or heart damage, strokes, having a post-operative infection, or dying. During anaesthesia, in most cases blood pressure is monitored using a cuff which inflates on the arm (the 'normal' way blood pressure is measured in a GP practice or hospital ward). This gives a reading each time the cuff goes up and down, every 3-5 minutes typically. There is a less well used way to measure blood pressure, using an additional cuff on the finger which gives a constant, continuous measure of blood pressure. We think that using this monitor, rather than the 'standard' monitor, will mean that low blood pressure is recognised more quickly, therefore treated more quickly, and will lead to patients having less exposure to dangerously low blood pressures. If this is the case, we hope that it will reduce how often patients experience kidney or heart damage, have an infection after surgery, suffer a stroke, and reduce the risk of death. Methodology To test this, we would need to run a large clinical trial comparing the continuous monitor to the standard monitor. This would be expensive and involve a great deal of work in a large number of hospitals, and so first we wish to determine whether the trial we would like to run is practical, and possible to deliver in the real world. To do this we plan to run the trial first on a small-scale feasibility (pilot) study, where we will recruit 30 patients, half of whom will have the standard monitor, and half of whom will have the continuous monitor. We will see what proportion of the patients who could enter the trial actually do so and complete it, and use it as an opportunity to iron out problems with the trial. If we find it is possible to run the trial on a small scale, we will apply for funding to run a full study. This will aim to answer the question of whether the continuous monitor improves the patient outcomes which were agreed during development with the patient public involvement group locally; rate of kidney damage, heart damage, stroke, post-operative infections, risk of death, and hospital length-of-stay. Expected outcomes and implications. We anticipate we will find the trial to be feasible with amendments to the way it is run, and if this is the case, we will apply to run the full scale trial. If this shows that using the continuous monitor improves the patient outcomes above, then it would represent new, significant evidence that may lead to the NHS adopting it's use as 'standard care' during anaesthesia for repair of a broken hip, and would like lead to similar trials in other operations where patients may benefit in a similar way.
A Study to Determine if Carbon Dioxide Lavage During Total Knee Surgery Reduces Intraoperative Embolic...
Postoperative ComplicationsMemory DisordersThe purpose of this study is to determine if the use of a carbon dioxide lavage device (CarboJet) to clean bone surfaces during total knee surgery decreases intraoperative embolic events when compared with standard orthopedic techniques.
Closure of Skin in ChorioAmnionitis Research Pilot Study
ChorioamnionitisPregnancy Complications3 moreThe purpose of the CSCAR pilot study is to improve the design of a full-scale trial by determining the patient recruitment rate and participation rate. The objective of the full-scale trial is to determine the optimal method of skin closure after Caesarean delivery in women with chorioamnionitis, which is an acute inflammation of the membranes and chorion of the placenta, seen typically after rupture of membranes with ascending polymicrobial bacterial infection. Women in labour with chorioamnionitis will be randomized at the time of Caesarean delivery to skin closure with either staples or sutures. The women will be followed at 6 weeks and 6 months post-partum in order to establish the occurrence of surgical site infection and wound disruption, as well as evaluation of the scar and other secondary questions. The investigators hypothesis is that closure of skin with sutures will have a rate of wound infection that is no higher than the rate of wound infection when closing skin with staples. The investigators also hypothesize that closure with sutures will have a decreased rate of wound disruption, increased patient satisfaction and decreased length of hospital stay compared to skin closure with staples.
Effect of Applying Cuff Air Leak Pressure as Intraoperative Cuff Pressure on Postoperative Complications...
Intubation ComplicationThe purpose of the study is to achieve effective ventilation with critical intracuff pressure (Pcr) and determine if application of Pcr reduces the risks associated with over-insufflation of endotracheal cuff including postoperative sore throat, cough,nausea, vomiting, aspiration, and pneumonia.
Evaluation of Postoperative Acute Kidney Injury (AKI) Incidence and Risk Factors in Patients Underwent...
Acute Kidney InjuryPneumonectomy; Status1 moreAcute kidney injury (AKI) is a critical complication associated with a high incidence of morbidity and mortality that can occur in critically ill patients and after major surgical procedures. The aim of this study is to identify the incidance and outcomes of patients underwent pneumonectomy, defined by Kidney Disease Improving Global Outcomes (KDIGO) criteria.
Intraoperative Hypocapnia in PROVHILO and PROBESE
Mechanical Ventilation ComplicationSurgery3 moreTo gain a better understanding of the epidemiology of intraoperative hypocapnia, in particular the associations of intraoperative hypocapnia with patient demographics, ventilator characteristics, and perioperative complications we will perform an individual patient-level meta-analysis of two recent randomized clinical trials of intraoperative ventilation, the 'PROtective Ventilation using High versus LOw PEEP trial' (PROVHILO), and the 'Protective intraoperative ventilation with higher versus lower levels of positive end-expiratory pressure in obese patients trial' (PROBESE).
Effect of Daytime Variation on PPCs in Lung Resection Surgery.
Postoperative ComplicationsThe aim of this retrospective study was to evaluate the association between daytime variation in surgery start time and the occurrence of postoperative pulmonary complications (PPCs) and postoperative adverse events (AEs) in patients who underwent lung resection under general anaesthesia.
Integrated Pulmonary Index Monitoring for Thoracic Surgery Patients
Postoperative ComplicationsMonitoringThe aim of this study was to investigate the effect of postoperative Integrated Pulmonary Index (IPI) scores on postoperative complications, blood gas analysis, mortality and morbidity in the patients undergoing thoracic surgery.
Evaluating the Effect of Surgical Safety Checklists on Perioperative Complications in Children
Intraoperative ComplicationsPostoperative ComplicationsThe purpose of this study is to see if the surgical safety checklist is associated with a reduction in perioperative complications for children undergoing surgery in Ontario, Canada.
Remote Ischemic Conditioning in Abdominal Surgery
LaparotomyLaparoscopy7 moreThis phase II randomized (1:1) controlled trial will examine the effects of remote ischemic conditioning (RIC) on the outcomes of major abdominal surgery. One hundred subjects will be enrolled at a single institution - University Hospital - Newark. The study population are patients undergoing major abdominal surgery (anticipated to be >/= 2 hrs long with a hospital stay >/= 2 days). Subjects in the treatment group will receive lower limb ischemic conditioning at 3 different time points: before surgery, POD 1 and POD 2. The primary outcome is the 30-day comprehensive complications index (CCI). Key secondary outcomes are changes in systemic inflammatory markers in peripheral blood and 30-day mortality.
