Brief summary
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 * Receive GDFT protocol or a conventional fluid therapy during the surgery. * Be continuously follow-up during hospitalization and after discharge to record the occurrence of postoperative complications.
Detailed description
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.
Interventions
PROCEDUREGoal-Directed Fluid Therapy
Stroke volume variation (SVV)≤12% and cardiac index (CI)≥2.5L/min/m2 are the goals of Goal-Directed 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.

Masking description
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Serious complications occurred within 30 days after surgery | within 30 days after surgery | Unit: %; All postoperative complications will be evaluated according the Clavien-Dino classification(CDc) of surgical complications. Each complication has an equal weight, and patients with at least one complication will be considered to have experienced postoperative complications. The serious postoperative complications were defined as CDc≥3. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| All complications within 30 days after surgery | within 30 days after surgery | Unit: %;All postoperative complications will be evaluated according the Clavien-Dino classification(CDc) of surgical complications. |
| The length of hospital stay after surgery | 1 months after operation | Unit: days; from date of operation till date of discharge |
| Cost of hospitalization | 1 months after operation | Unit: yuan; Total cost during hospitalization |
| Quality of Recovery Score | At 1,3, and 5 days after surgery | 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). |
