Advantage of surgical intensive care unit (SICU) predominant by cardiothoracic surgeons in multiple trauma management in a primary hospital.

PURPOSE: It is a challenge for the primary hospitals to manage multiple trauma patients. In this article, we explored the advantage of establishing a surgical intensive care unit (SICU) predominant by cardiothoracic surgeons in the early management of multiple trauma. METHODS: This was a retrospective study and patients with multiple trauma in our hospital were collected and divided into two groups, based on time period and treat modes: group A (retrospective observation group) where patients were treated with the traditional treatment mode from January 2017 to December 2017 and group B (study group) where patients were treated in the SICU predominant by cardiothoracic surgeons from January 2018 to December 2018. Clinical data including demographics, injury severity score (ISS), causes of injury, time intervals from reception to entering SICU or operating room and mortality three days after injuries were collected. Data were analyzed by SPSS 20.0 software. Categorical variables were presented as number and/or frequency and continuous variables as mean ± SD. RESULTS: Altogether 406 patients were included in this study, including 217 patients in group A and 189 patients in group B. General data between the two groups revealed no significant difference: mean age (years) (35.51 ± 12.97 vs. 33.62 ± 13.61, p = 0.631), gender distribution (mean/female, 130/87 vs. 116/73, p = 0.589) and ISS (15.92 ± 7.95 vs. 16.16 ± 6.89, p = 0.698). Fall from height were the dominant mechanism of injury, with 135 cases in group A (71.4%) and 121 cases in group B (55.8%), followed by traffic accidents. Injury mechanism showed no significant differences between two groups (p = 1.256). Introduction of the SICU significantly improved the care of trauma patients, regarding speed and mortality. Time intervals between reception and entering SICU or operating room was (108.23 ± 6.72) min and (45.67 ± 7.96) min in group A and B, respectively (p = 0.001). Mortality three days after injuries was 13.89% and 5.53% in group A and B, respectively (p = 0.005). CONCLUSION: Establishing a SICU predominant by cardiothoracic surgeons can reduce the early mortality rates in multiple trauma patients.

[Long term outcome of posterior lumbar pedicle screw fixation combined with isthmic bone graft fusion in the treatment of lumbar spondylolysis in young patients].

OBJECTIVE: To investigate the long-term effect of posterior lumbar pedicle screw fixation combined with isthmus bone grafting and fusion in young patients with spondylolysis. METHODS: A retrospective study was carried out, consisting of 16 young patients with lumbar spondylolysis without spondylolisthesis treated by lumbar posterior pedicle screw fixation combined with isthmic bone grafting fusion from January 2006 to July 2014. There were 11 males and 5 females, aged from 18 to 21 years old, with an average age of 19.3 years old, and the course of disease ranged from 12 to 26 months, with an average of 22 months. All the patients suffered from lumbar pain and difficulty in getting out of bed. Preoperative CT confirmed 12 cases of L5 isthmus fissure and 4 cases of L4 isthmus fissure. Bone graft fusion was confirmed and internal fixation was removed after operation. Lumbar spondylolysis was evaluated by lumbago visual analogue scoring method at preoperative and postoperative time points. Lumbar isthmic fusion was evaluated by lumbar CT, and degeneration of fixed and adjacent segments of lumbar intervertebral disc was evaluated by lumbar MRI. RESULTS: Of the 16 patients, 13 patients (26 sides) were followed up, with a mean duration of 96 months. The operation time ranged from 80 to 105 minutes, with an average of 95 minutes. The intraoperative bleeding volume ranged from 150 to 300 ml, with an average of 225 ml. All the patients were successfully operated without any complications related to the operation. VAS scores at each time point after operation were improved compared with those before operation(P<0.01). Postoperative CT scans of lumbar spine showed osseous fusion at 6 to 14 months, with an average of 12 months. There were no changes of adjacent segment degeneration, fixed segment disc degeneration and protrusion on lumbar spine MRI, and no symptomatic recurrence or recurrent spondylolysis in the long term. CONCLUSIONS: The posterior lumbar pedicle screw fixation combined with isthmic bone grafting and fusion is safe and effective in the treatment of young spondylolysis. The fusion rate is high and the interference of normal physiological range is reduced. The long-term effect is satisfactory.
