Assisted Fluid Management IDE Study

The primary objective of this study is to evaluate the performance of the Acumen Assisted Fluid Management (AFM) Feature in its ability to predict a subject's fluid responsiveness. Subjects enrolled in the validation study will have their fluid management decisions guided by the AFM Feature.

Phase N/A

Standardised Perioperative Management of Patients Operated With Acute Abdominal Surgery

200-250 acute laparotomies are performed annually at NL. The operations are performed for a number of reasons, where operation due to ileus; with- or without bowel strangulation; operation for acute peritonitis due to different kinds of stomach- or bowel perforation and re-operations for complications to elective surgery are the most ...

Phase N/A

Prehabilitation for Elective Major Abdominal Surgery

Major abdominal surgery is a great stressor to patients and causes large physiological changes, leads to tissue trauma, immobility, psychological distress and reduced quality of life. Physical capacity appears to be an important predictor for postoperative recovery after major abdominal surgery. Prehabilitation is a concept that challenges the traditional models ...

Phase N/A

Precision Pain Management for Major Abdominal Surgery in Colorectal Surgery

The primary objectives of this study are to evaluate the potential for preoperative pharmacogenomics (PGx) testing to positively influence postoperative opioid use through visual analog scale (VAS) guided administration of narcotic equivalent and lower pain scores as measured by OBAS in patients undergoing major abdominal surgery.

Phase N/A

Mobilization Immediate After Abdominal Surgery

There are approximately 600 000 surgeries performed each year in Sweden. Advances in surgical technique have led to a more complex surgery on patients with more serious comorbidities. This, in turn, has led to longer operations, which expose patients to longer periods of anesthesia. During anesthesia, muscle relaxant is used, ...

Phase N/A

Gradual Versus Immediate Goal-dose Enteral Nutrition in Abdominal Surgery Patients

Patients after abdominal surgery will receive enteral nutrition for 2 days, if she/he can tolerate 30% of goal-dose EN, then she/he will be randomized to Gradual or immediate Goal-dose EN group at day 3. Patients in Gradual Goal-dose EN group will receive increased calories gradually by EN and will reach ...

Phase N/A

Perioperative Immunonutrition in Colorectal Cancer Patients Undergoing Abdominal Surgery

The immune system plays an important role in helping to kill and prevent cancers. Cells of the immune system, such as natural killer (NK) cells and T cells, do not work as well following surgery. Arginine, an amino acid, is fundamental in metabolic processes of the body. Surgery has shown ...

Phase N/A

Perioperative Endothelial Dysfunction in Patients Undergoing Major Acute Abdominal Surgery

The aim of the clinical study is: to examine the association between postoperative endothelial function, indirectly measured by reactive hyperemia index, and major adverse cardiovascular events including myocardial injury and cardiac death within 30, 90 and 365 days of acute abdominal surgery. to examine the association between postoperative endothelial function, ...

Phase N/A

Effects of Continuous Bilateral QL Analgesia After Open Abdominal Surgery

Eligible patients will be randomized 1:1 without stratification to bilateral continuous QL catheters with local anesthetic continuous infusion (QL block + IV patient-controlled analgesia group) or normal saline continuous infusion (IV patient-controlled analgesia group). In the postanesthesia care unit (PACU), patients will be given intravenous boluses of hydromorphone or fentanyl ...

Phase N/A

Paravertebral Block vs. General Anesthesia for Major Abdominal Surgery

Introduction Elderly patients are usually presented with higher risk for developing cardiopulmonary complications after general anesthesia (GA). The risk of adverse events in elderly patients increases with the combination of intraoperative fentanyl, opioid premedication and neuromuscular blockers. Bilateral paravertebral block (PVB) has been associated with favorable outcomes in patients undergoing ...
