Filter by:Studying the dynamics of red blood cell lysis, pfH, protective proteins and organ injury, limits will be set for safe levels of pfH following the use of CPB. These results will be compared to existing laboratory-based methods for determining red blood cell damage to predict CPB assist device safety. Further, results from the studies described in this proposal will help develop therapeutic strategies to benefit patients by early detection of pfH and clearance protein levels that occur during CPB.
Standard risk prediction models in cardiac surgery (such as EuroSCORE II or STS score) are designed to analyze solely the risk of short-term postoperative mortality. The postoperative morbidity, the ability to rehabilitate or the mid-term survival are not addressed by these means. Recently there have been some reports that addition of physical performance testing to the standard prediction models may provide prognostic value. There is a wide scale of various physical performance and frailty tests that could be used for this purpose, but they have not been confronted with each other yet. Moreover, the postoperative physical rehabilitation has not been objectively assessed in larger scale despite the significant improvement in technology. The hypothesisis of the study is that the preoperative outcomes of physical performance and frailty testing are able to predict the patient's reconvalescence after cardiac surgery in the short- and mid-term postoperatively. The aim is to analyze a set of tests with regard to their ability to predict postoperative reconvalescence, including the objective activity assessment (using Actigraph wGT3X-BT activity tracking device). Secondarily, the investigators aim to follow the patients up to 1 year postoperatively in terms of evaluating their mid-term outcomes.
This research is designed for experimental quantitative research and is conducted by simple random sampling. Both the control group and the experimental group provided preoperative routine nursing treatment and preoperative medical teaching manuals. The latter adds cognitive therapy and gamification evaluation. Both groups used CAM-ICU to assess the occurrence and duration of postoperative delirium, and DRS-R-98 was used to assess the severity of delirium. After collection, use SPSS 22.0 statistical software package for analysis and processing. The expected result is that the incidence of delirium, the duration of delirium, and the severity of delirium in the experimental group were significantly lower than those in the control group.
Many analgesic modalities have been investigated in pediatrics. The analgesic efficacy of bilateral ultrasound-guided erector spinae plane block in pediatric patients undergoing open midline sternotomy will be examined. Methods: 60 patients aged 3- 12 years will be randomly assigned into two groups: Control group will receive general anesthesia with bilateral sham erector spinae plane block at the level of T6 transverse process using 0.3 ml/kg normal saline on each side. Erector spinae plane block group will receive bilateral ultrasound-guided erector spinae plane block at the level of T6 transverse process using 0.3 ml/kg bupivacaine 0.25% (on each side) with a maximum dose of 2 mg/kg. The postoperative pain was assessed using Modified Objective Pain Scores (MOPS) which will be evaluated at 0, 1, 2, 4, 6, 8, 10, and 12 hours after extubation, total consumption of intraoperative fentanyl (1µg/kg IV in case of inadequate analgesia), time to first rescue analgesic administration and postoperative paracetamol consumption will be recorded over the first 24 hours postoperatively.
The aim of this study is to compare the effect of Ultrasound-Guided Pecto-Intercostal Fascial Block versus Transversus Thoracis Muscle Plane Block on Postoperative Pain Analgesia in Cardiac Surgery
Inadequate management of preoperative mental health disorders often contributes to poor postoperative outcomes, including increased rates of readmission, delirium, falls, and mortality. However, very little work has been done to improve perioperative mental health. In particular, there have been limited systematic efforts that identify evidence-based behavioral and pharmacological strategies that were originally developed for depression and anxiety in otherwise medically well psychiatric patients. A mental health intervention bundle, composed of behavioral and pharmacological strategies, can mitigate anxiety and depression symptoms during the perioperative period. However, lacking is conclusive evidence on effectiveness of such an intervention bundle focused on the delivery of perioperative mental health care in older surgical patients. Towards this end, the investigators will develop and test an intervention bundle that encompasses: (1) behavioral activation, and (2) medication optimization.
Avoidance of unnecessary blood transfusions has always been a focus of clinical research. The rate of perioperative red blood cell transfusion in patients undergoing cardiac surgery under cardiopulmonary bypass reaches between 50-70%, and the intraoperative red blood cell transfusion rate is 30-50%. Regarding whether and when to perform a blood transfusion, it is necessary to comprehensively consider the benefits and risks brought by blood transfusion. Previous studies on blood transfusion strategies have mainly focused on the hemoglobin threshold, but the hemoglobin level does not fully reflect the level of tissue oxygenation. Mixed venous blood oxygen saturation has been widely studied as a valuable indicator reflecting the balance of oxygen delivery and oxygen consumption. But due to the difficulty of placing a pulmonary artery floating catheter for monitoring, its clinical application is limited. Central venous oxygen saturation requires only a small collection of blood samples, which can reflect the oxygen saturation of the superior vena cava, and studies have shown that it can effectively guide the blood transfusion of patients undergoing cardiac surgery. Existing studies have shown that in critically ill patients, the use of arterial-venous oxygen difference > 3.7 mL as an indicator to guide blood transfusion can lead to a higher 90-day survival rate. However, the relationship between the arterial-venous oxygen difference and the incidence of adverse events in cardiac surgery patients under CPB remains unclear. Whether increasing the arterial-venous oxygen difference during surgery can reduce the incidence of postoperative adverse events remains to be clarified. This study intends to collect intraoperative arterial blood and central venous blood samples from cardiac surgery patients undergoing CPB, and analyze the relationship between arterial-venous oxygen difference and the incidence of postoperative adverse events.
Over the past decade, aortic valve replacement surgery has undergone significant changes in terms of both the approaches and the prostheses used. In parallel with the historical biological prostheses for aortic valve surgery, a new generation of bioprostheses has been marketed since 2008, with the entry of these new prostheses in the armatorium of the Amiens-Picardy University Hospital since 2010. These are rapid deployment prostheses or prostheses without sutures. As a result, patients undergoing aortic valve replacement have been able to benefit from this type of bioprosthesis during their procedures. There are few publications reporting the 5-year follow-up of these bioprostheses. The investigators therefore decided to follow up patients operated on by a new generation bioprosthesis to study the 5-year survival and the functioning of their bioprostheses, in order to make a scientific contribution to the follow-up of these valves. These patients will be compared to patients who have benefited from the implantation of traditional bioprostheses.
One of the most painful aspects of open heart surgery is the incision made through the skin and the sternum to access the heart (a "sternotomy"). Post-sternotomy pain is a potentially debilitating complication of surgery that slows recovery immediately after surgery and can lead to issues with chronic pain. Previous research has shown that by injecting local anesthesia in the pecto inter-fascial plane, the space between the pectoralis major and the intercostal muscles, pain relief can be provided. The investigators aim to assess if repeated injections of local anesthesia via catheters is a useful adjunct compared to routine care.
Postoperative bleeding in cardiac surgery is a frequent complication, and cardiac surgery utilizes 15-20% of the national blood supply. Packed red blood cells (pRBCs) are associated with worse short and long term outcomes. For each unit transfused, there is an additive risk of mortality (death) and cardiac adverse events. Despite current guidelines and numerous approaches to bleeding reduction, >50% of the patients undergoing cardiac surgery receive transfusions. Acute normovolemic hemodilution (ANH), a blood conservation technique that removes whole blood from a patient immediately prior to surgery, could be a valuable method to reduce transfusion in complex cardiac surgery. At the University of California, Los Angeles (UCLA), ANH is routinely utilized in patients who refuse allogenic blood transfusions such as Jehovah's Witnesses. ANH has been shown to be safe with minimal risk to patients. ANH has been studied in simple cardiac surgery, such as coronary artery bypass grafting, however it has not been studied in complex cardiac surgery, such as aortic surgery and adult congenital heart disease. ANH has been demonstrated to reduce pRBC transfusion in lower risk cardiac surgery without any significant complications. Complex heart surgery utilizes more blood products. This study could identify the benefits of ANH in a higher risk surgical group.
