Comparative Noninvasive Continuous Cardiac Output by the Clearsight With Invasive Monitoring by PICCO in Abdominal Major Surgery

In high-risk patients, it is now recommended to guide the intraoperative volume replacement via the stroke volume. Today, the most commonly used technique for estimating the stroke volume is the transpulmonary thermodilution and the arterial waveform analysis in the radial artery by PICCO. This technique has the disadvantage of being ...

Impact of Caloric and Protein Adequacy on Postoperative Clinical Outcomes of Patients Undergoing Major Abdominal Surgery

The role of nutritional therapy (TN) in the surgical patient is well described in the literature and is associated with reductions in postoperative complications, length of hospital stay, and mortality. Adequate determination of caloric and protein requirements is an essential step in the TN institution, avoiding hypoalimentation and hyperalimentation. Thus, ...

Fluid Loading in Abdominal Surgery: Saline Versus Hydroxyethyl Starch (FLASH Study)

Fluid administration is the mainstay treatment for suspected hypovolemia during surgery, but the effects of different crystalloid and colloid solutions on outcome remain poorly explored in surgical patients. Two recent international multicenter studies (6S and CHEST studies) have shown that, compared to crystalloid solutions, the use of hydroxyethyl starch (HES) ...


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 ...

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

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 ...
