Epidural Decompression Surgery Within 24 Hours After Acute Spinal Cord Injury Improves Spinal Nerve Function

Spinal Cord Injuries Clinical Trial

Official title: Epidural Decompression Surgery Within 24 Hours After Acute Spinal Cord Injury Improves Spinal Nerve Function: a Prospective, Multicenter, Non-randomized, Controlled Trial

Status Not yet recruiting

Clinical Trial Summary

To compare the effects of early (within 24 hours) and delayed (exceed 24 hours) epidural decompression surgery on the recovery of spinal nerve function in patients with acute spinal cord injury (complete and incomplete) at postoperative 6 months.

Clinical Trial Description

Whether early epidural decompression surgery can restore neurological function in patients with acute spinal cord injury (complete and incomplete), and an effective time window for epidural decompression, are still controversial.

This trial will verify whether early epidural decompression surgery is more conducive to the recovery of spinal nerve function in patients with acute spinal cord injury (complete and incomplete) compared with delayed surgery. This trial will begin in August 2017. Data analysis of 200 patients will be finished in December 2019. All results will be completed in December 2020. This trial will provide clinical evidences for the selection of timing of epidural decompression surgery in patients with complete and incomplete spinal cord injury.

Adverse events Adverse events will be obtained from patients or their legal representatives. Major adverse events will include: limb paralysis deterioration, re-operation, respirator use (more than 1 week), tracheostomy, septicemia, pneumonia, acute respiratory distress syndrome, atelectasis, other respiratory complications, wound infection (superficial and deep), urinary tract infection, other infections, gastrointestinal bleeding, peptic ulcer, intestinal obstruction, acute myocardial infarction, other heart events, pulmonary embolism, cerebrovascular complication, hepatic failure, renal failure, delirium and depression.

Statistical methods

1. All data will be analyzed using SPSS 19.0 software.

2. Normally distributed measurement data will be expressed as mean, SD, minimums, and maximums. Non-normally distributed measurement data will be expressed as the lower quartile (q1) and median and upper quartiles (q3). Count data will be presented as the percentage.

3. Measurement data among groups will be compared using two-sample t-test or Mann-Whitney U test.

4. Count data will be analyzed using chi square test or Fisher's exact test. Ranked data will be analyzed using Wilcoxon signed-rank test.

Sample size ASIA motor score is one of the main outcome measures. In accordance with a previous study (Chikuda et al., 2013), taking power = 0.8 with a significance level of α = 0.05, we will need 45 patients per group when the difference to be detected in the ASIA motor score between the groups is 12 points and the common standard deviation is 20. If we assume a patient loss rate of 20%, we will require 54 patients per group, totally 108 patients. We therefore aim to include 200 patients in accordance with previous conditions on acute spinal cord injury (complete and incomplete) treatment in participating units.

Data management

1. All data will be input into the spinal cord injury treatment database. After the completion of the study, the research group and third-party statistical staffs will carry out data collation and analysis.

2. The participating units are responsible for filling in the information database. Data consistency and logic will be checked by computer program combined with manual review. Any questions will be answered by the person in charge of the project and the main staff, and returned to the data management center, and then the data manager will modify and update the database.

3. All inspection procedures need to be repeated several times until there is no doubt. All changes and updates are required for recording and filing. It is strictly forbidden to use correction fluid or correction tape. All researchers are required to ensure that the data recorded in the case report forms are authentic. ;
