Filter by:Researchers aim to demonstrate that the use of phototherapy is feasible and may reduce acute postoperative pain based on recent literature. The primary objective is to demonstrate that displaying light-emitting diodes [LED] can be achieved in the ICU setting in after cardiac surgery.
Single blind feasibility trial using a binary 'traffic light' design to evaluate the feasibility of injecting normal physiological saline into the atria of patients at the time of clinically indicated open chest cardiac surgery.
This is a prospective, single-center, observational, cross-sectional cohort study, comparing nurse-performed bedside lung ultrasound to standard portable CXR, for the detection of pneumothorax in the cardiac surgery patient population, following chest tube removal. This study aims to be conducted at an academic, tertiary adult center cardio-vascular intensive care unit (CVICU at TGH).
Adult cardiac surgery ensures the surgical treatment of valvular and coronary pathologies and of heart failure with the placement of ventricular assistance. Extracorporeal circulation (ECC) is one of the major technical advances associated with cardiac surgery to replace cardiac and pulmonary functions during surgery. ECC can nevertheless lead to postoperative complications, the origin of which is linked to the patient's initial contact with the circuit and membranes of the ECC. This contact triggers a series of humoral and cellular reactions that occur in the first few hours after the ECC and the inflammatory syndrome post ECC fades on its own and usually disappears between the 4th and 6th postoperative day. If the inflammatory response post ECC is most often transient, certain conditions will maintain and intensify this response at the origin of postoperative complications, possibly leading to the patient's death. Among these situations, the investigators find the notion of emergency cardiac surgery, a patient's age over 75 years and a preoperative history of decompensated heart failure, renal failure or type 2 diabetes (T2D). The inflammasome family of receptors of the nucleotide oligomerization domain (NOD) type, pyrin domain containing 3, NLRP3, is a multi-protein platform of recent discovery which plays a major role in the signaling pathways of the innate inflammatory response. The role of the activation of the NLRP3 inflammasome in cardiovascular pathologies is now well established and its metabolic priming by hyperglycemia could explain the greater seriousness of these pathologies in T2D patients due to an exacerbated inflammatory response. What is the effect of T2D status on the inflammatory response post ECC, mediated by the NLRP3 inflammasome, in patients after cardiac surgery?
The aim of this study is to detect decreased patient activity level after discharge after cardiac surgery to prevent readmissions. Cardiac surgery is associated with a high chance of readmission within 30 days, common reasons being volume overload, arrhythmia, pulmonary complications, and infections. A decreased activity level often precedes those complications. Measuring patient activity levels using wearable activity trackers (Fitbit) may detect complications early and prompts the surgical team to contact the patient before a visit to the Emergency Room is warranted.
The primary objective of this study is to determine if the addition of PECS2 block provides superior post-operative analgesia for cardiac surgery patients after midline sternotomy compared to only standard-of-care post-operative pain medication.
The aims of this study are to evaluate the usefulness of various methods of quantifying right ventricular (RV) function using perioperative transoesophageal echocardiographic (TOE), compared with simultaneous transthoracic echocardiographic (TTE) findings.
This study will assess the effect of active postoperative temperature management and its effect on the cognitive function in patients following coronary artery bypass graft (CABG) surgery to determine if active postoperative temperature management to maintain normothermia reduces postoperative cognitive dysfunction (POCD) in this population. Additionally, the investigators will explore differences in temperature control variability by using temperature management wraps combined with acetaminophen vs. acetaminophen alone in a pilot arm.
This pilot randomized-controlled study will determine the feasibility of large study comparing individualized versus standard blood pressure (BP) management in patients undergoing cardiac surgery under cardiopulmonary bypass (CPB). Our hypothesis is that maintaining higher BP levels based on preoperative measurements will reduce the incidence of major complications (composite outcome).
The purpose of this study is to evaluate the effect of simple needle guide device for ultrasound-guided internal jugular vein catheterization in cardiac surgical patients
