Pulmonary influences on early post-operative recovery in patients after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy treatment: a retrospective study
BACKGROUND/AIMS Cytoreductive surgery and hyperthermic intraperitoneal perioperative chemotherapy (HIPEC) significantly improves patients survival with peritoneal carcinomatosis especially in low-grade tumor e.g. ovarian and appendiceal adenocarcinoma, peritoneal pseudomyxoma and grade I gastric and colorectal cancer. METHODOLOGY During a period of nine years, hemodynamic and cardiac functions combined with urinary output during hyperthermic intraoperative intraperitoneal chemotherapy were prospectively measured in 60 patients. RESULTS Statistically significant hemodynamic and cardiac parameters were characterized by an increased heart rate and cardiac output as well as decreased systemic vascular resistance associated with an increased body temperature and decreased effective circulating volume. The tendency of urinary output was to decrease as the therapy progressed. CONCLUSIONS HIPEC induces a hyperdynamic circulatory state requiring increased intravenous fluid administration, which avoids changes because of increased intra-abdominal pressure. Documented by normal blood pressure and adequate urinary output hemodynamic and intravenous fluids, titrated to frequent urinary output determination, can achieve cardiac stability.
