Background. Optimal intravascular blood volume, cardiac output and sufficient oxygen supply is a mainstay in major abdominal surgery. Adequate haemodynamic management can improve a favourable outcome and shorten the duration of hospital stay.
Our study anticipated different fluid and vasoactive drug consumption and less complications during the pancreatic surgery in the group of patients where extended haemodynamic monitoring was applied.
Materials and methods. 59 adult patients, ASA 2-3, undergoing elective pancreas surgery, were included in the study. In 29 patients in the study group (SG – extended haemodynamic monitoring), cardiac index (CI), mean arterial pressure (MAP) and nominal stroke index (SI) were maintained within 80% of baseline values with actions following study protocol. Patients’ groups were homogenous, even when divided into 4 subgroups (control group (CG) and without epidural catheter (EC), CG and with EC, SG and without EC, SG and with EC).
Intraoperative variables (amount of fluids, vasopressors, surgery duration) and hospitalisation duration, wound healing, reoperation, mortality and other complication were recorded on the postoperative days 3, 5, 8, 15 and on hospital discharge.
Results. There was no difference in ASA health status, intraoperative management and duration of hospitalisation in 4 subgroups. There is a significant difference in intraoperative use of vasopressor support between 4 subgroups (Fisher exact test, p=0,032). All patients in SG with EC required vasopressors. Number of patients with major complications were not statistically different between groups. Pulmonary embolism, postoperative food intolerance and myocardial infarction have occurred only in CG.
Conclusion. In our study there was no difference in overall fluid and vasoactive drug demand. Although in the studied subgroup of patients with additional epidural anaesthesia there was significantly increased demand for vasoactive drugs. The incidence of complication was low in both groups, however, some of major complications occurred only in CG.
