简要总结
This is a randomized controlled clinical trial which investigates whether goal directed fluid therapy( GDT ) would show the evidence of benefit from GDT in terms of lactate kinetics then may reduce postoperative complications in patients undergoing spine surgery, especially in prone positions.
详细描述
This is a single-center, randomized controlled clinical trial. Patients aged > 60 undergoing lumbar decompression surgery will be randomly assigned to either a GDT ( goal directed fluid therapy) group or a control group, who received conventional anesthesiologist-directed fluid therapy. Perioperative lactic acid concentrations with 7 different time point, intraoperative fluid balance and postoperative complications from admittance to 30 days after surgery were recorded. This RCT is conducted to show the evidence of benefit from GDT in terms of lactate kinetics then may reduce postoperative complications in patients undergoing spine surgery, especially in prone positions.

盲法说明
Patients were assigned to one of the two groups (control group and GDT group) using a computer-generated randomization scheme.Allocation concealment was obtained using number labeled opaque envelopes that were opened just before the surgery. Data were collected by persons unaware of treatment allocation.
