Filter by:After cardiothoracic surgery, a chest tube is placed in patients to maintain hemodynamic stability and cardiopulmonary function by evacuating air, blood, and fluid accumulated in the pleural, pericardial, or mediastinal space, and to prevent undesirable conditions such as pneumothorax, hemothorax, and pleural effusion. Chest tube removal (CTR); it is an experience that can cause moderate or severe pain and anxiety in patients due to friction and separation from the endothelium and other surrounding tissues in the entry area of the tube. Analgesic methods are often preferred in pain management. However, research reveals that patients experience pain during CTR despite the use of analgesics and anesthetics. Although pharmacological agents are the most commonly used method for pain relief during CTR, studies report that the response to pharmacological treatment is variable and may be inadequate for pain management during and after CTR, making pain management difficult. Considering that procedure-related anxiety disrupts the physiological and emotional state of the patient and the side effects and possible complications of analgesics used in pain management, such as respiratory distress and nausea, the importance of nurses' use of non-drug methods in reducing pain during CTR increases This research was designed as a randomized controlled experimental study to determine the effect of vibration and cold application on pain and anxiety associated with chest tube removal after coronary artery bypass graft surgery. The research was planned to be conducted in the Cardiovascular Surgery Intensive Care Unit and Surgical Services of a Thoracic and Cardiovascular Surgery Training and Research Hospital in Istanbul between January 2024 and January 2025. Patients' pain will be evaluated using VAS, blood pressure, and respiratory rate using a patient monitor, pulse and oxygen saturation using a pulse oximeter device, and the temperature of cold application gels using a digital infrared thermometer. All data will be collected by the same researcher, with the same tools and methods. A "data form" developed in line with the literature and STAI I-II (State and Trait Anxiety Scale) will be used as data collection tools.
Preoperative carbohydrates (CHO) supplement has been shown to alleviate postoperative insulin resistance (IR) in nondiabetic patients undergoing a variety of surgeries. However, it remains controversial whether preoperative CHO could yield similar effects in diabetic patients. Thus, the investigators design a randomized controlled trial investigating the impact of preoperative CHO on postoperative IR and clinical outcomes in diabetic patients undergoing cardiac surgery. The results of the study may give some clinical implications and further improve perioperative care for diabetic patients.
Remimazolam is a novel short-acting benzodiazepine drug that acts on the benzodiazepine binding site of gamma-aminobutryic acid (GABA) A receptor, is metabolized by esterase, and has a context-sensitive half-time of about 6-7 minutes. Looking at some previous studies using Remimazolam, the safety and efficacy as a general anesthetic have been sufficiently proven. In particular, compared to intravenous anesthetic agents such as propofol, the action time of anesthetics is relatively longer, but the frequency of hypotension is low. However, most studies have been conducted on patients of American Society Anesthesiologist (ASA) class I-II, and studies on patients with high severity have not yet been sufficiently secured. Therefore, this study aims to compare the efficacy and safety of Remimazolam as an anesthetic with Sevoflurane in terms of hemodynamics in patients with high severity undergoing OPCAB surgery.
The study aims to identify the Following: - 1. incidence and mortality of cardiac Surgery associated -AKI based on the new consensus diagnostic systems of KDIGO (Kidney Disease Improving Global Outcomes). 2. use of biomarkers for the early detection of clinical and subclinical cardiac Surgery associated-AKI. 3. risk factors and prediction models of cardiac Surgery associated-AKI. 4. optimal cardiac surgical procedures including conventional versus minimally invasive approaches, on-pump versus off-pump, and optimal management of cardiac surgical support including duration of CPB, perfusion pressure, hemodilution, and hypothermia during CPB. 5. controversial pharmacologic therapies for the prevention and treatment of cardiac Surgery associated-AKI including statins, sodium bicarbonate, and N-acetylcysteine (NAC).
To compare two different methods of protecting heart muscle from damage caused by a decreased blood supply. Exposure to the anaesthetic agent sevoflurane can allow the heart muscle to resist longer periods of low blood or oxygen supply without sustaining the amount of damage that it would otherwise expect to. The use of thoracic epidural analgesia improves the blood flow to the heart muscle and has also been shown to reduce the amount of damage the heart muscle may otherwise sustain. The aim of this study is to compare these two methods.
