This is a single center prospective randomized controlled study comparing the postoperative outcome after cytoreductive surgery in ovarian cancer patient after using restrictive or individualized goal-directed fluid replacement strategy (GDT). Aim of this study will be to test the hypothesis that intra-operative SVV-guided fluid optimization during ovarian cancer cytoreductive surgery:

1. reduces the postoperative length of hospital stay,
2. cost-effective,
3. GDT will be more beneficial in cases of PDS compared to IDS or cytoreductive procedures of shorter duration.
4. GDT improves intraoperative tissue perfusion/ oxygenation and improves immediate postoperative morbidity.

Intra-operatively fluid of choice in both groups will be lactate-free crystalloid at 1.0 ml/kg/h for maintenance and gelofusine for fluid bolus of 3ml/kg over 5 minutes. In group C intraoperative fluid therapy will include maintenance fluid and replacement of the surgical loss. Aim will be to maintain MAP \> 65 mmHg, CVP 8-12 cm H2O and urine output \> 0.5 ml/kg/h. In group G intraoperative fluid therapy will be targeted to SVV \<13%, SVI \> 35ml/m2/ beat, SVRI more than equal to 1900 dynes-sec/cm-5/m2 in addition to clinical parameters like MAP, CVP and urine output.

Primary outcome will be length of hospital stay (LOS). Secondary outcomes will be cost of surgical treatment episode (admission till fit to discharge), postoperative morbidity survey (POMS) and 30 day morbidity and mortality.

Aims \& objectives:

The purpose of the study is to test the hypothesis that intra-operative SVV-guided fluid optimization during ovarian cancer cytoreductive surgery -

1. Reduces the postoperative length of hospital stay.
2. GDT is more cost-effective.
3. GDT will be more beneficial in cases of PDS compared to IDS.
4. GDT reduces postoperative morbidity.

Justification for study:

Cytoreductive surgery in ovarian cancer is usually associated with significant fluid shift attributable to suboptimal nutritional status, prolonged preoperative starvation, intraoperative blood and fluid loss, pharmacological vasodilation by neuraxial (epidural) and systemic anaesthetic drugs, intraoperative evaporative loss and the vasodilation due to systemic inflammatory response to surgery (SIRS), which was comparatively more in case of ovarian surgery. This results in hypotension and altered hemodynamics in the intra-operative and immediate

post-operative settings and the need for rigorous hemodynamic monitoring in the perioperative period. Among 3 different strategies, liberal or conservative one is associated with risk of overhydration, whereas restrictive therapy can cause hypoperfusion and related complications. A goal-directed fluid therapy has been shown to optimise intravascular volume in major abdominal surgery, which is the key determinant of cardiac output and oxygen delivery to tissues. This strategy results in use of more advanced hemodynamic monitors and increased costs thereof, and possibly, more total fluid requirements. A restrictive fluid strategy targeting physiological parameters alone, utilizes less costly modalities of monitoring and less overall fluid infused. But total healthcare cost associated with reduced rate of complications and thereby less hospital stay can neutralize that extra-cost of advanced monitoring (approximately Rs 8,000 per patient for consumables) and become more cost effective. The current standard of care in Tata Medical Center (TMC) has been a fluid therapy guided by clinical parameters. Although there is strong evidence supporting goal-directed approach to perioperative fluid therapy in case of major abdominal surgery, which has also been incorporated in enhanced recovery protocol and adopted worldwide, there is no such evidence for gynaec-oncological surgery, especially in ovarian cancer. So, investigators would like to conduct the proposed study to find-out the optimal fluid management strategy for ovarian cytoreductive surgery. As previously mentioned, investigators' data might indicate that the standard approach may lead to tissue hypoperfusion and approximately 2-3 liters of deficit which needs replacement under monitoring in order to avoid fluid overload.

Arguably, all patients of major cytoreductive surgery should require goal directed therapy and therefore randomization can potentially harm a subset of patients who would then receive restricted therapy instead of goal directed therapy. However, the standard regimen which is currently used in our setting is restrictive and SVV is also being increasingly used routinely only at the clinician's discretion including in ovarian cancer cases. Therefore no harm is anticipated from this intervention in either group. The only implication is of cost and resources; goal directed therapy has resource implications- both in terms of availability of machine and additional cost to the patient due to the consumables. A non-randomized prospective observational study would be feasible but will not be able to select which patients would benefit maximum from GDT due to selection bias. Therefore, a randomized study may help to identify a select group of patients who might benefit the maximum and therefore SVV directed fluid administration could be further stratified to be cost-effective due to reduction of postoperative length of hospital stay and morbidity.

From personal communication investigators know that, 3 trials of perioperative fluid therapy are ongoing now in India. Out of those 3 trials, 2 are in abdominal surgery and one is in hyperthermic intraperitoneal chemotherapy (HIPEC) surgery. Other cancer centers expressed interest to undertake similar trial in ovarian cytoreductive surgery. Therefore investigators may collaborate with other centers in future for a larger study based on the results; however, at present a single institutional study will be conducted to minimize bias associated with heterogeneity in surgical practice on cytoreduction.

Benefit:

This study will help investigators to guide fluid therapy in the perioperative period in ovarian cancer patients undergoing cytoreductive surgeries. This study should also help to find a strategy to prevent both fluid overload as well as under filling to avoid hypo perfusion and organ damage in this vulnerable group of patients. This strategy can even be adopted in other patient populations undergoing colorectal, hepatobiliary, thoraco-abdominal and HIPEC surgeries. These data will also inform whether a stratified approach can be adopted to selectively use SVV monitoring according to the predicted surgical complexity, type of cytoreduction and duration of surgery to optimize resources and improve cost-effectiveness.

Risks This study will utilize an existing technology, which is already in use. Therefore SOPs will be followed including reporting of adverse events, monitoring, documentation and safety reporting. The intervention is fluid bolus guided by advanced haemodynamic parameters (EV1000 monitor). Therefore risks are theoretical only. Risks related to the invasive procedures are same in both arms, which include pneumothorax, haemothorax, haemo-pneumothorax, bleeding, catheter-related infection and peripheral ischemia.

Methodology:

Site of Study OT complex and Intensive Care Unit, Department of Anaesthesiology \& Critical Care, Tata Medical Center, Kolkata

Study Structure Design:

Prospective randomized controlled trial - Patients and assessors will be blinded.

Population: All ovarian cancer patients undergoing major debulking surgery at TMC Kolkata (except- completion staging).

Sample size:

The study design was based on a retrospective audit at TMC that found the current median postoperative length of stay to be 10 days after cytoreductive surgery in ovarian cancer. To detect a reduction of 2 post-operative days with median postoperative length of stay to be 10 days in the restrictive group and 8 days in the goal directed group with a SD=3 days for 80% power at a significance level of 0.05, 37 patients are needed in each group (Total=74). As there is a difference in the median postoperative length of stay between the PDS and IDS group as mentioned earlier, at least 20 patients in each of the IDS and PDS groups would be needed for both the goal directed and restrictive group.

So the study would continue till each of the four combinations: Goal Directed (IDS), Goal Directed (PDS), Control (IDS) and Control (PDS) have at least 20 patients. To account for possible 10% attrition rate/ loss to follow up, 44 patients would be required in each group

Method of Randomization:

In addition to having higher median LOS in hospital, patients undergoing PDS are more likely to have ascites, major peritoneal stripping, higher surgical complexities and intraoperative fluid loss. Therefore, pre-randomization stratification will be done for type of surgery. Patients would be enrolled separately into PDS and IDS groups. Then for each group, patients would be randomized to get the standard or the goal directed therapy mentioned in the sealed envelopes based on computer generated random numbers.

After randomization and inclusion into a study arm, patients will be excluded in an event of the following: the procedure is abandoned/ open and close, duration of procedure is less than 4 hours, and any critical incident during operation (i.e. major blood loss/ medical condition/ shock) requiring intense fluid resuscitation. Following factors will be analyzed for univariate and multivariate analysis: ASA status, duration of surgery in minutes, surgical complexity score, intraoperative fluid loss, total vs. partial peritonectomy, comorbidities (Possum-P), massive blood loss and transfusion. Analysis will be on a per protocol basis as well as intention to treat.

Blinding:

* As the envelope would be opened after induction of GA, the patient will be blinded to the group she is allocated to.
* Post operative data will be collected by the ICU Consultant/ medical officer and Gynaec-oncosurgery team, who would not be part of the study and unaware about the allocation will follow up patients and decide on fitness to discharge. Outcome will also be verified according to predefined criteria by other clinicians from Gynaec-oncosurgery team, who are not aware about the allocated study group.

Statistical Analysis:

All statistical analyses and all summary tables and listings will be prepared using SASÒ release 8.3 or higher (SAS Institute, Inc., Cary, NC). Standard descriptive summaries will include the N, mean, median, standard deviation, minimum and maximum for continuous variables, and the number and percent for categorical variables. All statistical test of comparison will be based on 5% level of significance.

A prospective, double-blinded study. The present study consisted in applying Stroke volume variation fluid guided therapy to old patients (65 years old) undergoing radical resection of colon surgery. The aim of this study is to compare the effects of norepinephrine and phenylephrine in treating perioperative hypotension, and to find the safest and most effective vasopressor for elderly.

Fluid management has a great influence on patient's morbidity, mortality and on the overall outcome.Goal directed therapy was proved by multiple studies to be a goal therapy in maintaining a stable hemodynamic state. Nevertheless, as the population worldwide is aging, elderly presenting for surgery are also increasing. This population is known for the multiple comorbidities and physiological changes which makes them prone to dehydration and hypotension. That's when we are going to use either Norepinephrine in one group or Phenylephrine in the other and compare the effects of both vasopressors.

Parameters we are going to use are: Hemodynamic (HR, MAP, CO, CI, SVV, SV); Tissue Oxygenation and perfusion (DO2, VO2, ERO2, CRT, Lactate, blood gas); Urine output.

intraoperative fluid management based on CVP

intraoperative fluid management based on SVV

During the surgery, patients in group S receive additional fluids (400 ml of normal saline or 200 ml of colloid) when SVV is less than 13.

Patients in group C receive additional fluids (400 ml of normal saline or 200 ml of colloid) when CVP is less 8 during the surgery.

In patients undergoing craniotomy, 0.9% normal saline is commonly administered in order to reduce cerebral edema. Excessive administration of 0.9% normal saline has been to reported to cause hyperchloremic metabolic acidosis. On the other hand, hypovolemia due to insufficient fluid replacement for perioperative loss can also result in metabolic acidosis by lactic acid accumulation. However, the guideline for perioperative fluid management has not been yet established. The investigators hypothesized that intraoperative fluid management according to SVV(Stroke Volume Variation)could reduce perioperative metabolic acidosis compared to those by CVP(Central Venous Pressure). Therefore, the study is trying to determine if intraoperative fluid administration based on SVV could reduce metabolic acidosis when compared with CVP in patients undergoing craniotomy due to brain tumor who receive 0.9% normal saline as main fluid regimen.
