Filter by:Esophagectomy serves as an exemplar of major operative trauma, with well-known risk of pulmonary, cardiac, anastomotic, and septic complications and the presence of postoperative complications after esophagectomies for cancer is associated with a reduced long-term survival. There is a paucity in the literature regarding postoperative renal outcomes after esophageal surgery, with a wide range of incidence. The investigators will conduct a historical cohort study aiming to evaluate the incidence of postoperative acute kidney injury in patients undergoing elective esophageal cancer surgery. Secondary, the investigators will assess the progression of the acute injury and the association with adverse pulmonary, cardiac, anastomotic, and septic events, as well as increase in hospital stay and mortality. The investigators will also identify risk factors associated with acute kidney injury occurrence.
Prospecrtive study including 20-30 randomized patients treated by open repair because of an TAAA larger than 55 mm During the surgery, a heart lung machine is applied for distal perfusion during aortic cross clamping to enable distal organ perfusion. Regardless an intensive inflammatory reaction is a well known effect after reperfusion, leading to a uncontrolled inflammation during th first days after surgery. This may be associated to bad outcome and decreased survival rates. By the application of a intraoperative cytokine and DAMP filter this negative ffect could be reduced, resulting in a better outcome after surgery.
The peripheral arterial disease (PAD) has been associated with all-cause and cardiovascular mortality. Despite minimally invasive endovascular techniques, patients with critical limb-threatening ischemia (CLTI) have a poor prognosis with a high mortality that is comparable that of cancer. The inflammatory activity has a crucial role for the development and prognosis of atherosclerosis. Recently, different inflammatory biomarkers such as the neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) and lymphocyte to monocyte ratio (LMR) have been associated with severity and prognosis in patients with PAD. Additionally, patients with CLTI present several independent risk factors for malnutrition. For this reason, malnutrition represents an independent risk factor for mortality and post-operative complications. In this context, the Prognostic Nutritional Index (PNI) associates the nutritional and inflammatory status of patients. This study shows the clinical applicability of the different pre-operative nutritional and inflammatory biomarkers in patients with CLTI. This study does not collect any patient identifiable information.
Point-of-care gastric ultrasound will be used to measure stomach contents postoperative in patients who underwent colorectal surgery. Stomach volume and status (empty or full) will be compared retrospectively to the standard clinical criteria for diet advancement to determine if stomach volume via ultrasound is associated with successful diet advancement, nausea/vomiting, nasogastric tube replacement, length of stay, and other clinical outcomes. Clinicians performing clinical care will be blinded to the ultrasound exam results.
Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) has prolonged the survival substantially for selected patients with peritoneal metastases from colorectal cancer.Bleeding and thromboembolic disease have been reported as postoperative complications related to this advanced open surgical treatment. However, perioperative changes in coagulation and fibrinolysis are only sparsely reported in the literature.The mainstay of treatment with curative intend of none-advanced colorectal cancer is minimally invasive laparoscopic surgery followed by adjuvant chemotherapy. The approach is considered associated with a lower risk of thromboembolic disease than open surgery. Despite differences in extent of surgery and thromboembolic risk the same extended thromboprophylaxis regimen for 28 days is currently prescribed to patients undergoing cytoreductive surgery with HIPEC as well as minimally invasive rectal cancer resection. This study aims to investigate all parts of the coagulation system and fibrinolysis, and thereby thromboembolic risk and potential bleeding in two groups of patients with different extent of surgical trauma: 1) Colorectal cancer patients undergoing cytoreductive surgery with HIPEC and 2) rectal cancer patients undergoing minimal invasive rectal cancer resection. Our hypothesis is that patients undergoing cytoreductive surgery with HIPEC are exposed to more aggravated alterations of coagulation and fibrinolysis than patients undergoing minimally invasive rectal cancer resection.
This will be a prospective, randomized, single-blinded controlled trial in which the investigators evaluate post-operative serum glucose control using conventional point-of-care glucose monitoring in the morning and before meals (standard of care) versus continuous glucose monitoring using the Medtronic Guardian™ Sensor 3 continuous glucose monitor. The investigators will compare the average daily glucose level in the post-operative period (through post-operative day five) between the two arms in patients with diabetic nephropathy immediately post-renal transplant. This will serve as a pilot study to in order to power a main study.
Open heart surgeries are one of the major and complicated surgeries performed frequently in the world due to the prolongation of life expectancy and developments in medicine. As a result of these operations, not only the heart and vessels, but also all organs and systems depending on the systemic circulation are affected. Some biological inflammation markers have been determinant in determining cardiovascular risk. High neutrophil count was associated with increased mortality, while low lymphocyte count was a strong constant predictor of mortality. In addition, increased serum uric acid (UA) levels have been found to be associated with obesity, dyslipidemia, and hypertension, which is associated with cardiovascular disease risk. The aim of this study is to investigate the effects of patients who underwent coronary bypass surgery under elective conditions in Karadeniz Technical University Faculty of Medicine between 2008-2020 on in-hospital and 1-year mortality based on preoperative neutrophil / lymphocyte ratios and uric acid values.
Elderly patients have a higher incidence of morbidity and mortality due to the interaction of various factors such as decreased physiological reserves, concomitant comorbidities, multiple drug use, cognitive dysfunction, and frailty. Surgical stress, pain and associated lung complications are common problems in open heart surgeries that can affect morbidity and mortality. With a good postoperative pain control and improved respiratory mechanics, complications that may develop in patients can be significantly prevented, and the hospital cost can be reduced and the workforce loss of patients can be reduced by reducing the length of hospital stay in the intensive care unit. Thoracic epidural analgesia (TEA) is an anesthetic analgesia method that has positive effects on many organ systems as well as providing good pain control and is frequently used in open heart surgery. The aim of this study is to investigate the effects of TEA on postoperative respiratory mechanics in geriatric patients, based on analgesia levels, extubation times, length of stay in intensive care, arterial blood gases, morbidity and mortality.
A prospective randomized double-blind study including patients ASA I-II, aged more than 18 years undergoing surgery under general anesthesia (GA) and endotracheal intubation. Patients were randomized allocated into 2 groups: ketamine group received ketamine gargle (0.5 mg/kg up to 30 ml dextrose water) and magnesium group received magnesium sulfate gargle (20 mg/kg up to 30 mL dextrose water ) 15 minutes before the operation. Our primary outcome is sore throat and the secondary judging criteria are cough, dysphonia and satisfaction. A standardized anesthesia protocol was followed for all patients. After extubation, the patients were asked to grade POST, hoarseness, and cough at 15 min, 1h, and 24 h.
The aim of this randomized clinical trial was to compare the incidence, intensity and duration of postoperative pain following the removal of root canal obturation materials canals using rotary (ProTaper Universal or Hyflex EDM) or reciprocating file (Reciproc Blue or WaveOne Gold) systems. The null hypothesis tested was that there is no difference in postoperative pain following the retreatment procedure between the four systems used.
