Please assess the completion status of the following clinical trial:

Trial Title: Closed-loop Fluid Administration System: Pilot Study to Evaluate Feasibility

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: SINGLE
- Phase: PHASE4
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Adult patients aged 18-75 years~* Scheduled for abdominal surgery under general anesthesia and requiring an invasive arterial blood pressure monitoring~* Consenting to participate in the study~Exclusion Criteria:~* Pregnant, breast feeding women~* Allergy~* Pacemaker~* Psychiatric disease, dementia, brain disease~* Contraindication to hydroxyethyl starch~* Inability to measure pulse pressure variability : arrhythmia, spontaneous breathing, or tidal volume \< 7 ml/Kg

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: 75 Years
- Healthy Volunteers: f

Study Arms:
- Open loop (Type: ACTIVE_COMPARATOR): fluid replacement (hydroxyethyl starch 130/0.4) is decided by the physicians according to continuous cardiac output measured by LidCO rapid device
- Closed-loop (Type: EXPERIMENTAL): Fluid replacement is automated. An algorithm has been developed ; the input value is continuous cardiac output measured by LidCO rapid device; the computer steers iv infusion of hydroxyethyl starch 130/0.4.

Based on this trial design, predict the completion outcome and termination type (if applicable).
