Objective: To investigate clinical effects of strategy by stages for preventing respiratory complications of patients with acute cervical spinal cord injury (ACSCI).
Methods: From September 2009 to May 2013,the clinical data of 91 patients with ACSCI underwent surgery were retrospectively analyzed. Among the patients, 42 patients were divided into in-stages group, including 30 males and 12 females with an average age of 50 years old (ranged 28 to 76) which were treated with strategy by stages for preventing respiratory complications; others 49 patients which were not treated with the strategy regarded as control group, including 38 males and 11 females with an average age of 47 years old (ranged 30 to 77). All of them had definite history of trauma, and were admitted to orthopaedics within 48 h after trauma. In in-stages group, respiratory muscle strength training, high-dose ambroxol using and other treatment were performed to prevent respiratory complilcations according to preoperative, intraoperative and postoperative stage. While in control group, there were no systematic and effective measures utilized. Chi-square test was used to evaluate the difference for respiratory complications rate, the rate of tracheostomy or intubation and mortality caused by the respiratory complications between two groups.
Results: Ten patients developed with respiratory complications in in-stages group (7 patients with pneumonia, 1 with atelectasis and 2 with respiratory failure), among which 3 patients underwent tracheostomy or intubation. In control group, 24 patients developed with respiratory complilcations (15 with pneumonia,3 with atelectasis and 6 with respiratory failure), among which 11 patients underwent tracheostomy or intubation. There was significant difference between two groups (χ2 = 6.12, 4.07; P = 0.013, 0.044). Five patients died because of respiratory complications, one case were in in-stages group and 4 in control group. There was significant difference between two groups (χ2 = l.39, P = 0.238).
Conclusion: The strategy by stages is an effective method for preventing respiratory complications of ACSCI and can reduce the respiratory complications rate and improve the prognosis of respiratory complications.
