Purpose: To study the relevant factors affecting the duration of mechanical ventilation in the patients with acute low level cervical spinal cord injury (CSCI)graded ASIA A and ASIA B after operation.
Materials and Methods: The 116 patients with acute low level CSCI graded ASIA A and ASIA B who underwent surgical decompression and stabilization were divided into two groups according to whether or not the duration of mechanical ventilation after operation was longer than 24 hours. Ten variables, including clinical and experimental variables, were analyzed by t test for continuous variables and χ2 test for discrete variables. The variables with significance (p＜0.05) were then analyzed with stepwise logistic regression.
Results: three continuous preoperative clinical and experimental variables, including the presence of neurogenic shock , peripheral leukocytes（/mm3）and Peripheral neutrophilic granulocyte,（%）revealed significant differences between the two groups. Stepwise logistic regression analysis for three variables indicated that the presence of neurogenic shock is the relevant independent risk factors.
Conclusion: The presence of neurogenic shock is the relevant independent risk factor affecting the time of ventilation in patients with acute low level CSCI graded ASIA A and ASIA B after operation.
