Filter by:In the reduction mammoplasty operations performed in the Plastic and Reconstructive surgery operating room in our clinic, the female patient group, who does not have co-morbidities and does not exceed middle age, is followed by infusion of crystalloid at a constant rate of 4 ml/kg. If the mean arterial pressure (MAP) is <65 mmHg, it is treated with fluid boluses, and in cases where no response is obtained, with noradrenaline boluses. However, in this process, frequent and severe hypotensive episodes are observed, especially after removal of more than a few kilograms of breast tissue. In these hypotensive episodes, factors other than the blood volume lost with the tissue may also play a role. For this reason, we aimed to evaluate the iNOS levels by assuming that the blood levels of "inducible nitric oxide synthetase" (iNOS), which is stored in large amounts in adipose tissues and has been shown to play a role in lipid metabolism, may increase with the manipulation of breast tissue, and accordingly increased nitric oxide may lead to hypotension.
To compare the goal-directed fluid therapy based on the data obtained from the hemodynamic monitoring system, which provides continuous CO, SV and SVV measurements through arterial pressure wave with standard fluid therapy in perioperative fluid management of patients undergoing head and neck surgery.
Patients who are scheduled for: elective oesophageal tumour resection, total gastrectomy, pancreas resection, major vascular, total cystectomy will be recruited.To investigate effects of central venous pressure (CVP) and central venous saturation (ScvO2) guided fluid management on intraoperative haemodynamic parameters, volume and vasopressor requirement, and postoperative organ function and postoperative inflammatory response.
