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

Piloting Prehabilitation Before Abdominal Surgery

Background: Frail Veterans are at increased risk for poor surgical outcomes. Although surgeons operate safely on even the oldest old, if the elder is also frail, the stress of surgery can result in significant mortality, morbidity, and institutionalization. Frailty is a clinical syndrome marked by muscle atrophy, diminished strength, decreased ...

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

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 ...

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

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

S1316 Surgery or Non-Surgical Management in Treating Patients With Intra-Abdominal Cancer and Bowel Obstruction

This partially randomized clinical trial studies surgery or non-surgical management in treating patients with intra-abdominal cancer and bowel obstruction. Bowel obstruction is a common problem for advanced cancer patients and can negatively affect quality of life. It is not yet known whether surgery or non-surgical management is the best treatment ...

Phase N/A

Flux Measurement and Outcome in Major Abdominal Surgery

Surgical resection is the primary therapy for a variety of benign and malignant diseases of the gastrointestinal tract. Advances in the perioperative care surgical technique and imaging modalities have significantly improved the outcome of patients with major abdominal resections within the past three decades. However, the incidence of postoperative complications ...

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

Influence of Open and Laparoscopic Abdominal Surgery Involving the Intestinal Tract on Serum 1 3- -D-Glucan (BDG) Values

Candida species are both known to colonize physiologically mucosal surfaces in the human body without causing signs or symptoms of infection and to cause a wide variety of diseases, including mucocutaneous infections and potentially fatal invasive infections of the bloodstream or organs. Throughout the past decades, invasive fungal infections (IFIs) ...
