Filter by:The purpose of this study is to compare the values of Surgical Pleth Index (SPI) and Nociception Level Index (NOL) measured simultaneously during cardiac surgery.
The aim of the study was to assess the ability a Lung Recruitment Maneuver (LRM) with a stepwise increase of PEEP to predict fluid responsiveness and right cardiac dysfunction in mechanically ventilated patients in open heart cardiac surgery. During different phases, all patients received a Passive Leg Raising (PLR) maneuver for preload status evaluation using the PICCO system, a Lung Recruitment Maneuver (LRM) and an echographic evaluation of the right cardiac function. 20 patients were analyzed. Incomplete Lung Recruitment Maneuver (LRM) can predict fluid responsiveness at phase 1, pre-operatively, with a sensitivity of 0.57 and specificity of 0.62. Performance of an incomplete Magnetic Resonance Angiography (MRA) to predict right cardiac dysfunction based on TAPSE post-operatively provides a sensitivity and specificity of respectively 0.33 and 0.17 Tolerance to a stepwise lung recruitment maneuver can not be used to evaluate reliably the preload responsiveness and guide fluid therapy except pre-operatively. The use of a lung recruitment maneuver can be a promising method for right cardiac dysfunction screening but further studies need to be done with different echographic tools for right cardiac dysfunction evaluation.
A randomized, parallel group, active comparator-controlled trial to evaluate the non-inferiority or superiority of Cryopreserved Platelets with Liquid Stored Platelets in controlling blood loss in patients undergoing Cardiopulmonary Bypass 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).
To evaluate the differences between serum cystatin C based estimated glomerular filtration rate (eGFRcys), serum creatinine based eGFR (eGFRcreat) and measured glomerular filtration rate (mGFR) in subjects at high risk for acute kidney injury (AKI) approximately 90 days following cardiac surgery
The aim of this retrospective study will be to investigate the effect of the preoperative administration of levosimendan on the outcome of patients with compromised cardiac function undergoing cardiac surgery
The aim of this study is to examine effects of dental treatments, surgical (extractions) and non-surgical procedures (non-surgical periodontal therapy), on serum levels for PCR, WBCs and PCT in patients needing a dental remediation before undergoing cardiac surgery.
Endocan is a proteoglycan produced by the vascular endothelium. Animal studies suggested that the synthesis mainly happen in the pulmonary circulation, but this hypothesis has never been confirmed in humans.
Postoperative atrial fibrillation (POAF) is a common complication that occurs in 30-50% of patients after cardiac surgery and increases morbidity and mortality and hospital length of stay. During the perioperative period, the discontinuation of beta-blocker treatment is known to be a risk factor for developing POAF in patient undergoing cardiac surgery. Early beta-blocker reintroduction is associated with lower incidence of POAF. Unfortunately, side effects of currently available beta-blockers (including esmolol), such as low blood pressure and excessive bradycardia and/or their extended duration of action, limit their use in the post-operative period especially for prevention. Landiolol, an ultra-short acting injectable beta-blocker, offers the advantage of significantly limiting low blood pressure events while increasing therapeutic efficacy in the treatment of POAF in cardiac and non-cardiac surgery. Landiolol, when used at low dose in the postoperative period, has been showed to reduce the incidence of POAF with no increased incidence of side effect as compared to standard of care. The limitation is that these promising data come from single center studies with limited samples and conducted exclusively in Japanese population. If landiolol is approved for use in the treatment of atrial fibrillation in non-Asian patients, there are no data on the prevention of POAF in cardiac surgery. The objective of this multicenter, double-blind, randomized, placebo- controlled phase III trial is to confirm that landiolol postoperative infusion is associated with lower incidence of POAF without excess of adverse events as compared to standard of care in a non-Asian population after cardiac surgery with sternotomy.
