Effect of Prone Positional Apparatus on the Occurrence of Acute Kidney Injury After Spine Surgery.

Abstract

Background and objective

Increased intra-abdominal pressure with prone positioning for spinal surgery is associated with intraoperative hemodynamic alterations and the potential for postoperative complications. This study investigated the incidence of postoperative acute kidney injury (AKI) in patients undergoing spine surgery on a Jackson spinal table or a Wilson frame.

Methods

A total of 1374 patients who underwent spine surgery were divided into 2 groups: Jackson spinal table (n = 598) and Wilson frame group (n = 776). After 1:1 propensity score matching, a final analysis was performed on 970 patients. The primary endpoint was a comparison of the incidence of AKI in the 2 groups.

Results

After propensity score matching analysis, the mean ± standard deviations of spine surgery invasiveness index were 4.7 ± 3.5 and 2.1 ± 1.4 in patients with the Jackson spinal table and the Wilson frame, respectively (P < 0.001). Considering the differences in surgical invasiveness, operative time, estimated blood loss, and administration of packed red blood cells were higher in the Jackson spinal table group than in the Wilson frame group (P < 0.001). However, the incidence of AKI was less with the Jackson spinal table than with the Wilson frame (1.7% vs. 3.7%, 2.25 [0.978-5.175], P = 0.056), not reaching statistical significance.

Conclusion

This analysis showed that postoperative AKI in patients undergoing spine surgery in the prone position was not different with the Wilson frame than in the Jackson spinal table despite higher surgical severity, longer operative times, and more blood loss in the latter group. In spine surgery, the appropriate selection of prone positioning apparatus can potentially be an important consideration in reducing the risk of AKI.
