Brief summary
Tissue oximetry obtained from peripheral muscle measures the state of tissue oxygenation of various organs and, as already widely described in the literature, can be used to measure the state of kidney's tissue oxygenation. However, there is no evidence in the existing scientific literature on the use of muscle tissue oximetry in patients undergoing cytoreductive surgery for ovarian cancer with hyperthermic intraperitoneal chemotherapy. The primary objective of our study is to evaluate whether there is a correlation between average intraoperative muscle tissue oximetry below 65% (a value which is considered critical in the literature for the resulting cellular damage) and postoperative renal damage in patients undergoing cytoreductive surgery with hyperthermic intraperitoneal chemotherapy for ovarian cancer.
Detailed description
Tissue oximetry obtained from peripheral muscle can be used to measure the state of kidney's tissue oxygenation. 50 Adult female patients ASA 1-2 undergoing cytoreductive surgery with laparoscopic or laparotomy technique (for ovarian cancer) associated with hyperthermic intraperitoneal chemotherapy will be enrolled. The primary objective of our study is to evaluate whether there is a correlation between average intraoperative muscle tissue oximetry below 65% (a value which is considered critical in the literature for the resulting cellular damage) and postoperative renal damage (according to the AKIN and KIDGO classification) in patients undergoing cytoreductive surgery with hyperthermic intraperitoneal chemotherapy for ovarian cancer. Secondary objectives are: * describe the variation in muscle tissue oximetry and hemodynamic parameters (systolic, mean, diastolic blood pressure) during cytoreductive surgery with hyperthermic intraperitoneal chemotherapy . * describe the variation in renal function values (blood urea nitrogen, creatinine) and serum electrolytes (sodium, potassium, chloremia, calcemia) in the post-operative period (from the first to the seventh postoperative day).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Correlation between intraoperative tissue oximetry and postoperative acute renal injury. | Tissue oximetry is defined as TWA (time-weighted average) value resulted by values recorded intraoperatively every 20 minutes. | An intraoperative mean tissue oximetry value of 65% or less is considered to predict cellular damage. Postoperative renal injury is classified according to AKIN and KIDGO criteria. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
