Active clinical trials for "Postoperative Complications"

High concentrations of parathyroid hormone (PTH) are common in patients with hepatocellular carcinoma (HCC). This study is aimed to investigate effects of vitamin D status and its multiple mega-dosage supplementation on PTH and clinical outcomes in HCC patients before and after hepatectomy. It's a single-center, prospective, parallel, double-blind, placebo-controlled study for 120 eligible subjects. The subjects will receive consecutively 3-day intervention treatments from 7th day before surgery. 30-day postoperative mortality, postoperative complications, and laboratory data will be evaluated.

Perioperative organ injuriy remain an important threat to patients undergoing major surgeries. Intraoperative hypotension is associated with an increase in postoperative morbidity and mortality. Whereas individualized intraoperative blood pressure management is likely to decrease the incidence of postoperative organ injury when compared with standard blood pressure management strategy. Dexmedetomidine, a highly selective alpha2 adrenergic agonist, has been shown to provide organ protective effects. This study aims to investigate the impact of intraoperative goal-directed blood pressure management and dexmedetomidine infusion on incidence of postoperative organ injury in high-risk patients undergoing major surgery.

Study is conducted to assess the prevalence and structure of comorbidity among patients undergoing abdominal surgery and produce the stratification of the risk of postoperative complications by identifying independent predictors for its development.

Surgical operations and recovery after anesthesia is a complex process. Studies examining the interventions performed in the preoperative period often focus on classical clinical outcomes such as postoperative organ dysfunction, morbidity or complications. Postoperative recovery of the patient is rarely considered the most important outcome variable in interventional studies. In this study, the Quality of recovery 15 (QoR - 15) questionnaire that measures the recovery score, and the American college of surgeons surgical risk calculator have been used to compare the predictive values of patient's preoperative condition on postoperative recovery period and possible morbidity and mortality.

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.

The aim of this study is to make a precise inventory of the complications that may occur postoperatively in the more or less long term in a cohort of patients who should benefit from surgical management of Hallux Valgus.

Postoperative mortality within 30 days after surgery is around 2% in patients having major noncardiac surgery in Europe and the USA. In fact, if the first 30 days after surgery were considered a disease, it would be the third leading cause of death globally. Postoperative deaths are a consequence of postoperative organ injury and complications - including acute myocardial injury, acute kidney injury, and severe infectious complications. To avoid postoperative deaths, it is thus crucial to reduce postoperative organ injury and complications. To reduce postoperative organ injury and complications, modifiable risk factors need to be addressed. These modifiable risk factors for postoperative organ injury include low blood flow states and intraoperative hypotension. Optimizing blood flow (i.e., cardiac index) during surgery may thus be effective in reducing postoperative organ injury and complications. However, the optimal hemodynamic treatment strategy for high-risk surgical patients remains unclear. Cardiac index varies substantially between individuals. However, current intraoperative hemodynamic treatment strategies mainly aim to maximize cardiac index instead of using personalized cardiac index targets for each individual patient. A single-center pilot trial suggests that using individualized cardiac index targets during surgery may reduce postoperative organ injury and complications compared to routine hemodynamic management. However, large robust trials investigating the effect of personalized hemodynamic management targeting preoperative baseline cardiac index on postoperative complications are missing. The investigators, therefore, propose a multicenter randomized trial to test the hypothesis that personalized hemodynamic management targeting preoperative baseline cardiac index reduces the incidence of a composite outcome of acute kidney injury, acute myocardial injury, non-fatal cardiac arrest, severe infectious complications, and death within 7 days after surgery compared to routine hemodynamic management in high-risk patients having major abdominal surgery.

The investigators aim to establish a prospective database of perioperative elderly patients from multiple regions and centers. Collected data involves postoperative complications of the central nervous system, cardiovascular system, kidney, respiratory system, infection, pain, and other perioperative complications. Based on the database, the investigators intend to explore: The incidence and risk factors of perioperative morbidity and mortality in elderly patients; Perioperative risk assessment methods and early warning models for elderly patients; Practical, safe, and effective risk prevention and control system through subsequent studies.

Patients suffering from pancreas cancer as well as patients with chronic pancreatitis or requiring pancreas surgery often are in a compromised nutritional status. Nutritional support should therefore be started early during the postoperative course to prevent further malnutrition, as it is an important risk factor to develop complications. Recently, several studies have shown that early enteral nutrition (EEN) could shorten length of stay, reduce postoperative infections and mortality, and decrease costs when compared with total parenteral nutrition (TPN) in gastrointestinal cancer surgery. After pancreatoduodenectomy (PD), EEN has been shown to reduce early and late complications, infections, and readmission rates. It is nevertheless currently not clear if EEN improves the short-term outcomes after PD compared to oral nutrition. The primary objective of the study is to assess the impact of EEN on postoperative morbidity after PD, according to the Comprehensive Complication Index. Secondary objectives are to assess the impact of EEN on major postoperative complications, according to Clavien classification, specific complications, length of stay, readmission rates, quality of life, metabolic stress and nutritional response after PD.

Introduction: Aiming at reducing costs and optimizing the use of these financial resources, several postoperative recovery protocols have emerged that aim to reduce the length of hospital stay by accelerating surgical recovery.1,2 In view of the current Brazilian political and economic scenario allied to the existing scientific knowledge on the subject , the investigators developed a protocol that aims to meet this need using resources already available and offered in brazilian public health system. The investigators called this protocol as Protocol of Operative Recovery Santa Marcelina (PROSM) that had as inspiration the protocols of accelerated postoperative recovery already used in several European health services. Goals: To evaluate the impact of PROSM on the length of hospitalization in days and postoperative pain (visual analog pain scale - VAS) in patients submitted to surgical procedures performed by the thoracic surgery team of the Hospital Santa Marcelina de Itaquera. Evaluate the impacts of PROSM in reducing the costs (US dollars) of surgical treatment and hospitalization of these patients. Materials and methods: A group of 200 patients with elective pulmonary resections (segmentectomies, lobectomies or pneumonectomies) to treat neoplastic lung diseases will be selected by the investigators. The participants will be randomized into two groups (rate of randomization 1/1). The first group will be submitted to the standard surgical treatment that is currently used in Santa Marcelina - Itaquera hospital. The second group will be submitted to treatment with the adoption of the PROSM guidelines, which will be detailed later. Investigators will evaluate in the two groups: surgical time in minutes, intraoperative complications: intraoperative bleeding in mililiters, need for transfusion of blood products, intraoperative clinical complications. Investigators will also evaluate the need for postoperative recovery in Intensive Care Unit (ICU), medications used to maintain the anesthetic plane during the procedure (amount of drugs in milligrams), medications used for postoperative analgesia, length of hospital stay in days, postoperative clinical complications, need for surgical re-boarding, immediate postoperative pain (VAS), postoperative pain at the time of discharge and the first outpatient return (VAS), the need for opioid analgesics at home after discharge. After the data collection, the investigators will analyze them and make a comparative study of the costs of surgical treatment and hospitalization between the two groups. This data will be obtained from the billing department of the Hospital Santa Marcelina de Itaquera.
