Active clinical trials for "Postoperative Complications"

Mobilisation following knee arthroplasty is an important aspect to achieve early and enhanced recovery after surgery and sufficient joint function. Analgesia is a crucial therapeutic element in this context. This RCT evaluates two analgetic regimens for patients undergoing primary total knee-replacement to assess impact on postoperative recovery.

This study evaluates surgical site complications in subjects undergoing revision of a total knee arthroplasty when closed incision negative pressure therapy is used to manage the closed incision, as compared to a standard of care dressing.

Hypothesis: Fluid management guided by stroke volume variation (SVV), compared with central venous pressure (CVP), guidance results in better clinical outcomes. Primary outcomes: Perioperative, up to 48 h postoperative, serum lactate and creatinine level. Methods: Adult patients undergoing endovascular aortic aneurysm repair (EVAR) will be randomized into 2 groups: SVV group managed by SVV guidance and CVP group managed by CVP guidance. Outcome analyses: Compare serum lactate, creatinine as well as other postoperative complications between both groups.

This study evaluates the impact of local anesthetic administration regiment through peri-neural femoral nerve catheter on pain and motor block frequency, after total knee arthroplasty.

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.

A trial in which patients having open abdominal surgery are randomized to receive either crystalloids or colloids intraoperatively, guided by esophageal Doppler. The investigators test the primary hypothesis that goal-directed colloid administration during elective abdominal surgery decreases a composite of postoperative complications within 30 days of surgery.

Goal directed volume therapy means that bolus doses of 150-250 ml colloid fluid is administered to the patient during contemporary measurement of the patients stroke volume. The fluid status is considered optimized when stroke volume no longer increases with more than 10%, indicating that the patient is close to the top of the Frank-Starling curve. Several studies show that volume optimization reduces hospital stay and reduces the amount of surgical complications. The overall purpose is to investigate if the much more simple non invasive technique Pleth Variability Index can replace oesophageal doppler to guide volume therapy in routine health care, and to analyse if a volume kinetic test can be used to evaluate hypovolemia before surgery and make specific rehydration possible by analysing the correlation between this test and fluid optimization using stroke volume measurements. Primary hypothesis: 1. The volume of colloids that is given to volume optimise an anesthetized patient using Pleth Variability Index shows a good correlation to the volume used if volume optimisation is undertaken by the guidance of oesophageal doppler. 2. Data from the two methods correlate and discriminates similarly volume responders from non responders. 3. A volume kinetic model that indicates dehydration can predict the need for rehydration in order to achieve a well hydrated patient at start of surgery.

The study is designed to investigate the influence of parenteral nutrition (PN) with low nitrogen and calorie supply on the clinical outcome of patients after an operation compared to that of traditional PNs.

The purpose of this study is to demonstrate the bioequivalence of the combination test agent, prednisolone acetate 1.0% and tobramycin 0.3% ophthalmic suspension compared to PredForte (prednisolone acetate 1.0%) ophthalmic suspension. Bioequivalence will be measured by comparing aqueous humor concentrations of prednisolone acetate.

The current study hypothesizes that the use of Intravenous intensive insulin therapy (IV-IIT) may be beneficial than IV conventional insulin therapy (IV-CIT) for improving the outcome of non-diabetic surgical patients had postoperative (PO) stress hyperglycemia (PSH).
