The goal of this clinical trial is to evaluate whether goal-directed fluid therapy (GDFT) can improve the postoperative recovery in patients undergoing head and neck cancer surgery. It aims to answer is:
• Whether GDFT can reduce the occurrence of serious postoperative complications? Researchers will compare GDFT protocol to a standard conventional fluid therapy in head and neck cancer surgery to see if GDFT strategy works to improve the postoperative recovery.
Participants will
Postoperative complications have become the main cause of prolonged hospitalization and reduced postoperative survival rate among surgical patients. Goal-Directed Fluid Therapy (GDFT) has been reported to reduce the incidence of postoperative complications and mortality, shorten the hospital stay, and improve the outcome in major abdominal surgery patients. However, the benefit of the GDFT in patients undergoing head and neck surgery remains controversial. The purpose of this study is to evaluate whether GDFT can reduce the occurrence of serious postoperative complications and shorten the postoperative hospital stay, compared with a standard conventional fluid therapy in patients undergoing head and neck cancer surgery.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| GDFT group | Experimental | Patients in GDFT group will receive GDFT protocol, Stroke volume variation (SVV)≤12% and cardiac index (CI)≥2.5L/min/m2 are the goals of fluid therapy, while the mean arterial pressure (MAP) are kept between 65 and 90 mmHg. 5mL/kg of crystalloids will be infused during induction period, followed by an infusion rate of 2 mL/kg/h to supplement the physiological requirements. If SVV>12% for more than 5 min, a 250 mL bolus of colloid is given. Another 250 ml bolus of colloid is administrated if SVV was still more than 12% or SV decreased over 10%. If the CI<2.5 L/min/m2, inotropes are used to achieve this minimum CI, serving as a safety parameter to prevent the patient from being exposure to a low cardiac output state. If SVV and CI reached the s target range but MAP could not maintain the expected level, vasopressors were started. Assess the patients every 5min intraoperatively to ensure that all parameters adhere to the target range according to the study algorithm. |
|
| conventional fluid therapy group | No Intervention | Patients in conventional fluid therapy group, fluid management will be carried out according to the clinical practice routine, maintaining MAP≥65mmHg and urine output ≥0.5ml/kg/h, intraoperatively. When the anesthesiologist empirically determines that the fluid infusion is sufficient but MAP does not maintain the expected level, vasopressor or inotropic drugs are given to maintain the blood pressure. |

Patients were unaware of their group allocation. Due to the presence of the cardiac index trend monitoring device, care providers who supported to fluid strategy administration in the operating room could not be blinded. The outcomes assessor were blinded to the allocation.

| Cost of hospitalization | Unit: yuan; Total cost during hospitalization | 1 months after operation |
| Quality of Recovery Score | Unit: point; Use QoR-15 to evaluate the postoperative recovery of all patients. QoR-15 is a global measure of recovery after surgery that evaluates five dimensions of recovery: physical comfort (5 items), physical independence (2 items), emotional state (4 items), psychological support (2 items), and pain (2 items). Each item is rated on an 11- point scale based on its frequency on the questionnaire (greater score at greater frequency for positive items and less frequency for negative items). The total score ranged from 0 (poorest recovery quality) to 150 (best recovery quality). | At 1,3, and 5 days after surgery |
