6 Clinical Trials for Various Conditions
Evidence thus suggests that steroid administration, tight glucose control, and avoidance of deep anesthesia may decrease perioperative morbidity by reducing the inflammatory response to surgery. Using a three-way factorial approach, the investigators thus propose to test the primary hypotheses that major perioperative morbidity is reduced by: 1) low-dose dexamethasone; 2) intensive perioperative glucose control; and 3) lighter anesthesia. Secondary hypotheses include that each intervention reduces circulating concentrations of the inflammatory marker CRP, and that there is a correlation between C-reactive protein (CRP) and post-operative complications. Anesthetic sensitivity predicts major and minor complications, and delirium Other secondary hypotheses are that each intervention, reduces minor surgical complications, reduces postoperative nausea and vomiting (PONV), reduces postoperative delirium, speeds hospital discharge, improves quality of life (SF-12v2 Health Survey, Christensen's VAS fatigue score), and reduces all-cause one-year mortality.
The investigators propose a pilot clinical trial on the use of perioperative pregabalin in order to decrease ureteral stent related symptoms and decrease opioid usage after ureteroscopy with stent placement. Patients undergoing ureteroscopy with stent placement will receive a single dose of 300 mg pregabalin PO in the preoperative area. This work will assess safety and feasibility of studying this regimen at our institution, with the aim of performing a randomized, placebo-controlled, double-blinded study in the future.
Our objective was to determine whether a standard 1mg/kg intraoperative dose of dexamethasone results in similar drug levels for all patients and to characterize the relationship between these drug levels and the innate stress response following infant Cardiopulmonary Bypass (CPB). The investigators hypothesized that postoperative dexamethasone levels are highly variable, and that the infant stress response is inversely related to the amount of dexamethasone measured in the blood. To test this theory the investigators simultaneously measured blood levels of dexamethasone and cortisol at critical time points during the perioperative period for infants undergoing CPB for CHD surgery.
Subjects undergoing surgery on the small or large bowel will be randomized to one of 2 groups, a normal fluid amount group and a reduced fluid amount group to evaluate the impact of this change on recovery after surgery.
High blood glucose levels in surgical patients with and without diabetes are associated with increased risk of medical complications and death. Over the short-term, high blood glucose can adversely affect fluid balance, impair immunologic response to infection, and promote inflammation and endothelial dysfunction (blood vessel function). Blood glucose control with intensive insulin therapy in patients with critical illness (very sick patients in intensive care unit) reduces the risk of multiorgan failure and systemic infections, and decreases short- and long-term mortality. High blood glucose has also been associated with poor outcome in non-critically ill patients admitted to general surgical and medical wards; however, intensive glycemic control is not aggressively pursued because of fear of hypoglycemia. A computerized search of biomedical journal literature from MEDLINE, PubMed, and Ovid from 1966 to 2008 provided very little information on the prevalence and outcome of high blood glucose during the perioperative period (before and after surgery) in non-critically ill patients. Therefore, the present study aims to evaluate the impact of high blood glucose, in large number of subjects with and without diabetes, during general (non-cardiac) surgery.
It is the long term objective of this study to preserve or improve the quality of life and to prevent deterioration in physical and mental function following myocardial revascularization among bypass surgery patients.
