Relationship between impairment and magnetic resonance imaging finding in patients with traumatic cervical spinal cord injury after surgery / 中国康复理论与实践

ObjectiveTo explore the application of Brain and Spinal Injury Center (BASIC) score in evaluation of traumatic cervical spinal cord injury. MethodsFrom January, 2015 to December, 2021, 175 patients with traumatic cervical spinal cord injury in Beijing Bo'ai Hospital were analyzed. Gender, age, cause of injury, injury mechanism and American Spinal Injury Association Impairment Scale (AIS) grade were collected. The sagittal and axial T2 weighted imaging (T2WI) of the patients were evaluated with BASIC score, single/multi-segment injury, and with/without intramedullary hemorrhage. According to the injury mechanism, the patients were divided into two groups: with fracture/fracture dislocation (n = 92) and without fracture and dislocation (n = 83). The baseline demographic indicators and T2WI evaluation indicators were compared between the two groups, and the relationship between AIS grade and BASIC score, intramedullary hemorrhage, single/multi-segment injury were investigated. ResultsThere were significant differences in gender, age and AIS grade, BASIC score, and the rates of inntramedullary hemorrhage and single segment injury of T2WI between two groups (t = -10.276, χ2 > 8.703, P < 0.01); however, no difference was found in the cause of injury (P > 0.05). The AIS grade was significantly correlated with the BASIC score (r = 0.790, P < 0.001). There was significant difference in AIS grade between intramedullary hemorrhage or not, and single/multi-segment injury (χ2 > 5.516, P < 0.05). ConclusionThe BASIC score of T2WI is a predictor of the severity of spinal cord injury after traumatic cervical spinal cord injury, and is different with the injury mechanisms.

Training load, stress, recovery, mood, and motivation of athletes with spinal cord injury in wheelchair rugby during a competitive preseason

Abstract Aim: This study aims to characterize the stress, recovery, mood, and motivation together with the training load of athletes with cervical spinal cord injury (CSCI) during a period of resumption of wheelchair rugby (WCR) training. Additionally, it aims to compare the psychological and load training aspects during a competitive preseason and determine the correlations between training load, mood, stress, and recovery. Methods: We evaluated variables such as mood (Brazilian Mood Scale, BRAMS), stress and recovery (Recovery-Stress Questionnaire for Athletes, RESTQ-Sport 76) and training load (Subjective Perception of Effort - SPE) of eight high-performance athletes of wheelchair rugby with CSCIs at three different times (E1 = returning from vacation, E2 = half of the preseason, and E3 = after 2 months of training) for 2 months at a monthly interval. We also evaluated motivation (Sport Motivation Scale) at E1 and E3. Results: Results indicated few changes during the competitive preseason in terms of stress, recovery, and mood. However, the training load decreased toward the end of this period. Furthermore, we found that physical complaints positively correlated with depression when resuming training. In the middle of the competitive preseason period, we also noted positive correlations between conflict/pressure and fatigue and between fatigue and energy loss. At the end of this period, the SPE and arbitrary units correlated positively with conflict/pressure. Conclusion: We found few changes during the competitive preseason in terms of stress, recovery, and mood but not motivation, which did not change during this period. On the other hand, the training load decreased at the end of the competitive preseason. Furthermore, we observed correlations between training load and psychological aspects at different times.

A case-control study:the clinical efficacy of total laminectomy with lateral mass screw fixation and single open-door laminoplasty for cervical spinal cord injury without fracture and dislocation / 中国骨伤

OBJECTIVE@#To compare the clinical effects of total laminectomy with lateral mass screw fixation and single open-door laminoplasty in the treatment of cervical spinal cord injury without fracture and dislocation.@*METHODS@#The clinical data of 75 patients with cervical spinal cord injury without fracture and dislocation treated from December 2014 to April 2020 were retrospectively analyzed, including 65 males and 10 females, aged from 33 to 83 years old with an average of (60.1±11.4) years. According to surgical method, the patients were divided into observation group (36 cases) and control group (39 cases). The observation group was treated with C3-C6 single open-door laminoplasty. In the control group, the C3-C6 whole lamina was opened by "uncovering", and the lateral mass screw was fixed and fused. The general conditions including operation time, intraoperative blood loss, hospital stay and complications such as axial pain, cerebrospinal fluid leakage, postoperative C5 nerve palsy were recorded. Visual analogue scale(VAS), Nurick pain scale, Japanese Orthopaedic Association(JOA) scores and American Spinal Injury Association(AISA) injury scale were used to evaluate the improvement of clinical symptoms and related functional recovery 12 months after operation.@*RESULTS@#There were no statistically significant differences in operation time, intraoperative blood loss and hospital stay between two groups(P>0.05). There were statistically significant differences in JOA, VAS, ASIA and Nurick scores of the all patients between 12 months after surgery and before surgery (P<0.05), and there was no significant difference between groups. There was significant difference in the incidence of C5 nerve root palsy and axial pain between two groups(P<0.05), but there was no significant difference in the complications of cerebrospinal fluid leakage between two groups (P>0.05).@*CONCLUSION@#Total laminectomy with lateral mass screw fixation and single open-door laminoplasty in treating cervical spinal cord injury without fracture and dislocation can obtain satisfactory results in restoring nerve function, alleviating pain and improving daily behavior, but single open-door laminoplasty has the advantages of less trauma and low incidence of complications.

Multivariate analysis of the operative effect on cervical spinal cord injury without fracture or dislocation / 中国骨伤

OBJECTIVE@#To explore the influencing factors of the operative effect on cervical spinal cord injury without fracture or dislocation.@*METHODS@#The clinical data of 69 patients with cervical spinal cord injury without fracture or dislocation from November 2010 to November 2016 who received operation were retrospectively analyzed. There were 37 males and 32 females, aged from 32 to76 years with an average of (51.6±7.3) years. The clinical data of 12 factors were selected, including age, gender, ASIA grade of spine cord injury, the length of spine cord injury by MRI, Pavlov ratio, ossification of the posterior longitudinal ligament (OPLL), intervertebral disc herniation, type of spine cord injury by MRI, time from injury to operation, treatment of high-dose methylprednisolone, operation time, intraoperative bleeding volume. In order to screen the main influencing factors of above items to prognosis, the single factor and multiple factor Logistic regression analysis were used in the clinical data by SPSS 22.0 statistical software.@*RESULTS@#Univariate analysis results showed that the factors including ASIA grade of spine cord injury, the length of spine cord injury by MRI, Pavlov ratio, ossification of longitudinal ligament, intervertebral disc herniation, the type of spine cord injury by MRI were associated with prognosis (<0.05). Multi factor analysis of the selected factors indicated that the type of spine cord injury by MRI, the length of spine cord injury by MRI, Pavlov ratio, ASIA grade of spine cord injury were the main prognostic factors according to the influence intensity (<0.05).@*CONCLUSION@#The influencing factors of the operative effect on cervical spinal cord injury without fracture and dislocation were the type of spine cord injury by MRI, the length of spine cord injury by MRI, Pavlov ratio, ASIA grade of spine cord injury, and the foremost were the type and length of spine cord injury by MRI. Compared with other patients, preoperative MRI showed the patient with spinal cord injury type with bleeding and edema, or the length of spine cord injury larger than 45 mm may be less effective, therefore, it is necessary to thoroughly communicate with the patients and their kin before surgery.

Application of self-made transfer band in patients with cervical spinal cord injury / 中国实用护理杂志

Objective@#To make a postural transfer belt for patients with cervical spinal cord injury, to reduce and prevent the corresponding nursing problems with traditional methods of transfer@*Methods@#44 patients with cervical spinal cord injury admitted to the ward from January to June 2017 were selected as the control group by traditional methods of postural metastasis, and 48 patients with cervical spinal cord injury admitted to the ward from July to December 2017 were selected as the observation group by using self-made transfer belt.@*Results@#Number of the skin injury caused by transfer in observation group was 0 cases, in control group was four cases, and there was significant difference (χ2=1.91, P=0.049). Falls occur due to metastasis: there were 0 cases in the observation group and five cases in the control group, there was significant difference (χ2=2.39, P=0.026). The number of caregivers in the observation group decreased on average (1.21±0.08), and the number of caregivers in the control group decreased on average (0.86±0.09). The differences between the two groups are statistically significant (t=2.905, P=0.005). The results of the investigation on the escorts in the observation group showed that 46 (95.8%) people believed that the transfer belt was convenient for patients. 47 people believed that the transfer belt was safer and more labor-saving to use, accounting for 97.9%, and 47 people believed that the transfer belt would continue to be used when they went home, who occupied 97.9%.@*Conclusion@#The self-made transfer belt is convenient for the caregivers to carry the patients with cervical spinal cord injury, which effectively prevents the occurrence of skin injury, falls and other nursing problems, and improves the quality and experience of the caregivers. This technology is worthwhile to spread.

The role of high-flow nasal cannula oxygen therapy in patients with high cervical spinal cord injury / 中华急诊医学杂志

Objective To study the effect of high-flow nasal cannula oxygen therapy (HFNC) in reduction in re-intubation rate, length of ICU stay and improvement of respiratory function in patients with high cervical spinal cord injury.Methods Single center retrospective study was carried out in our intensive care unit from September 2016 to March 2018. Post-operative patients ready for planned extubation with high cervical spinal cord injury were included. The length of ICU stay, re-intubation rate in case of respiratory failure, respiratory rate, pulse rate, MAP, SaO2, PaO2/FiO2, and PaCO2 of patients at 6, 24 and 72 h after extubation were compared between the HFNC and conventional oxygen therapy (COT) groups. Results During the study period, 38 patients were enrolled in the study. Of them, 16 patients were assigned in the HFNC group and 22patients in the COT group. Re-intubation rate was significantly different between the two groups (18.8％ vs 27.3％, P<0.05), but the length of ICU stay had no significant difference [(15.5±3.4) days vs (16.6±5.2) days]. The respiratory rate, pulse rate, SaO2 and PaO2/FiO2 at 6 h after extubation in the HFNC group were improved markedly than those in the COT group (P<0.05); and the PaCO2 and PaO2/FiO2 at 24 and 72 h after extubation in the HFNC group had much more improvement than those in the COT group (P<0.05). Conclusions Among individuals with post-operative high cervical spinal cord injury, high-flow oxygen therapy could reduce re-intubation rate, and PaCO2 level, and improve the respiratory function, but cannot reduce the length of ICU stay. High-flow oxygen therapy may offer advantages for patients with high cervical spinal cord injury.

Comparison of clinical treatment of traumatic cervical spinal cord injuries with acute respiratory failure treated by high-flow nasal cannula therapy and non-invasive positive pressure ventilation / 中华急诊医学杂志

Objective To compare the clinical efficacy of high-flow nasal cannula oxygen therapy (HFNC) with non-invasive positive pressure ventilation (NPPV) in patients with traumatic cervical spinal cord injury complicated with acute respiratory failure (ARF).Methods A prospective randomized controlled trial was performed in EICU of the First Affiliated Hospital of Zhengzhou University from May 2016 to January 2018.One hundred sixty-eight consecutive patients with traumatic cervical spinal cord injury complicated with ARF,who did not respond to conventional oxygen therapy,were assigned to the HFNC or NPPV treatment group sequenced by the random number table.The baseline clinical characteristics of randomized participants and respiratory frequency (RR),PaCO2,mean arterial pressure (MAP) at 1,12,24,48 h after treatment were evaluated.Comfortable scale,tracheal intubation rate within 28 d,duration of mechanical ventilation,length of stay in ICU and mortality rate were compared as well.Results There was no significant differences in baseline clinical characteristics,such as sex,age.between the two groups (P＞0.05).RR and PaCO2 were lower in the HFNC group at all time point.In addition,the HFNC group had significantly lower PaCO2 than the NPPV group at 24 and 48 h after treatment (P＜0.01);Oxygenation index (PaO2/FiO2) was improved in both groups,and the HFNC group had superior oxygenation index than the NPPV group at 12,24,48 h after treatment (P＜0.01).Furthermore,the HFNC group had better comfort scale (6.93±0.71 vs 4.29±0.93,P＜0.01),shorter length of stay in ICU and duration of mechanical ventilation compared to the NPPV group (P＜0.01).There was no significant differences in tracheal intubation rate and mortality rate between the two groups (P＞0.05).Conclusions In addition to the superior efficacy in improving respiratory function and shortening length of stay in ICU,HFNC was well tolerated by patients with traumatic cervical spinal cord injury complicated with ARF,and could be recommended in clinical practice.

Epidemiological analysis of traumatic cervical spinal cord injury / 中华急诊医学杂志

Objective To describe the epidemiological characteristics of cervical spine fracture combined with trauma cervical spinal cord injury (TCSCI) in Guangxi province. Methods A total of 385 patients met the inclusion criteria were enrolled for retrospective investigation. Detailed information included age, sex, marital status, occupation, date of admission, mechanisms of trauma, level of injury, ASIA grade, concomitant injuries, length of hospital stay, complications, and mortality. Results The ratio of Male/Female was 4.4:1. The average age of the patients was 47.9 years, and 88.8％ of the patients were married. 72.9％ of TCSCI occurred between the age of 35-64 years. Farmers accounted for the largest number of patients with TCSCIs, and 63％ of patients with TCSCI were caused by falling. The damage was located at the C3-C5 level, accounting for 63.8％. More than half of the patients with CSCI had brain injury. The most common complication was respiratory infection (54.5％). Among the injury levels, the proportions of ASIA grade A, B, C, and D were 34.8％, 8.5％, 35.5％, and 21％, respectively. During the treatment, 58 patients required cardiopulmonary resuscitation, and 36 patients required mechanical ventilation. The average length of hospital stay was (26.5±21.6) d. Of the 375 patients discharged from the hospital, 51.2％ patients had no improvement in the muscle strength. Conclusions Falling is the main cause of CSCI and men are more likely to be exposed to the injury. Patients with TCSCI have long treatment time and poor treatment results. Additionally, complications during the treatment should not be ignored.

Profile of the cardiac repolarization in cervical spinal cord injury subjects performing physical exercise / Perfil da repolarização cardíaca de sujeitos com lesão medular cervical submetidos a exercícios físicos

The aim of the study was to compare rest QT interval and QTcorrected intervals of electrocardiogram in trained men with and without cervical spinal cord injury (CSCI) and investigate cardiac electrocardiogram parameters in trained men with CSCI submitted to maximal effort test. Thirty men were separated into three groups: Control without CSCI (CON, 25.3 ± 4.1 yrs, strength training: 3 days week-1; aerobic training 1day week-1; n = 10), high volume exercise (30.5 ± 4.3 yrs, 3 day week-1 rugby specific exercises, 60min. day-1; n = 12) and moderate volume of exercise (33.7 ± 5.9 yrs, 2 days week- 1 specific rugby exercises, 60 min. day-1; n = 8) with incomplete CSCI (C5-C7 cervical vertrebae) more than 12 months. Electrocardiogram was recorded in rest, during and after effort test. QT interval was significantly reduced (p = 0.001) in the high volume exercise group compared to control. Corrected QT interval showed no difference between moderate vs. high volume exercise group (p > 0.05). No changes were observed in QT, corrected QT, PR and QRS intervals of electrocardiogram between rest and post effort (p > 0.05). Thus, effort test does not change electrocardiogram parameters in CSCI subjects. High volume of week exercise promotes abnormalities in cardiac repolarization compared to a moderate training program.

O objetivo do presente estudo foi comparar o perfil dos intervalos QT e QT corrigido (QTc) em homens treinados com e sem lesão medular cervical (LMC) e investigar o perfil eletrocardiográfico de homens treinados com LMC submetidos ao teste de esforço máximo. Trinta homens foram separados em três grupos: controle sem LMC (CON, indivíduos fisicamente ativos; n = 10), LMC praticantes de alto volume de exercícios (praticantes de rugby em cadeira de rodas 180 min. Semana-1; n = 12) e LMC praticantes de moderado volume de exercícios (praticantes de rugby em cadeira de rodas 120 min. Semana-1; n = 8). Todos os participantes do grupo LMC apresentavam lesões incompletas (C5-C7) mais do que 12 meses. Eletrocardiograma foi registrado em repouso, durante e após o teste de esforço. O intervalo QT apresentou redução significativa (p = 0,001) no grupo de alto volume de exercícios quando comparado ao controle. O QTc não mostrou diferença entre os distintos volumes de exercícios (p > 0,05). Ambos os grupos LMC não apresentaram mudanças significativas no intervalo QT, QTc, intervalos PR e QRS entre o repouso e pós-esforço (p > 0,05). Concluimos que o alto volume de exercícios semanais parece promover anormalidades na repolarização cardíaca.

Epidemiology of traumatic cervical spinal cord injury in ICU / 中华急诊医学杂志

Objective To investigate the epidemiological characteristics of traumatic cervical spinal cord injury (TCSCI) in ICU.Method The data of patients with TCSCI admitted from October 2010 to March 2016 in the intensive care unit were retrospectively studied.The general epidemiological data included:gender,age,marital status,occupation,cause of injury,injury severity,injured segment (ASIA grade),and complications were collected.Results There were 109 patients identified to have TCSCI with mean age of 53.72 ± 14.86 years (25.69％ patients in the range of 60-69 years old).The male to female ratio was 9:1,and the most were married.The majority of individuals were retired (30.27％),and the main causes of injury were traffic accidents and tumble.The C5 segment of the spine was the most vulnerable to be injured,and then the C4 segment was the nest in turn.There were up to 30.28％ patients suffered from multiple injuries,and 26.61％ patients also had a craniocerebral injury.Bedsore and respiratory system complications were the two leading complications,and 83 patients suffered from at least one system dysfunction with respiratory dysfunction accounted for 98.79％ and circulatory dysfunction accounted for 65.06％.Fifty-one patients presented more than two system dysfunctions (46.79％).Twenty patients (18.35％) died.Conclusion Patients with TCSCI in ICU presented specially characteristic features.Traffic accidents were the main cause of TCSCI,and fall accidents were one of the main causes in the elderly.The mortality of TCSCI was high,especially in males.The complication rate was relatively high and the most common complications were water and electrolyte disturbance and respiratory dysfunction.Multiple organ dysfunction incidences might be associated with the ASIA grades.

Methods A retrospective research on seventy-nine patients with acute cervical spinal cord injury who underwent tracheostomy in our hospital from January 2011 to December 2015 was conducted .The 79 patients were divided into two groups.The patients with a duration from intubation to tracheostomy less than or equal to 10 days were enrolled in group A , and the duration more than 10 days, group B.The duration of ventilation , the length of ICU stay , and the incidence rate of lung infection were compared between the two groups . Results The duration of ventilation in the group A (192 ±58) h was less than that in the group B (348 ±53) h (t=-12.490, P=0.000).The length of ICU stay in the group A (9.8 ±2.7) d was less than that in the group B (15.9 ±2.2) d (t=-11.058, P=0.000).The incidence of pneumonia in the group A (16.2%, 6/37) was lower than that in the group B (38.1%, 16/42,χ2 =4.686, P=0.030).Mechanical ventilation was successfully withdrawn in 34 and 38 cases of group A and B, without significant difference (χ2 =0.000, P=1.000). Conclusion Early tracheostomy in patients with acute cervical spinal cord injury who need ventilation for a long time could shorten the duration of ventilation and the length of ICU stay , and decrease the incidence of pneumonia .

Prophylactic surgery is invalid intreatment of spinal injury without fracture and dislocationcomplicated by cervical spinal canal stenosis / 实用医学杂志

Objective In this study,we aim to evaluate the risk and incidence of traumatic cervical spinal cord injury (CSCI) in patients with traumatic cervical spinal canal stenosis (CSCS) without major fracture or dislocation,and evaluate the feasibility of preventive decompression surgery. Methods This study included eighty?seven patients with traumatic CSCI without major fracture or dislocation treated in our department between 2005 and 2012. Mann?Whitney U test was used for statistical analyses. Analysis of variance (ANOVA) was used to calculate the relative and absolute risks for the incidence of traumatic CSCI without major fracture or dislocation related with CSCS. Results The relative risk for the incidence of traumatic CSCI with CSCS was 145.7 times higher than that for the incidence without CSCS. However ,only 0.000026% of patients with CSCS may be able to avoid developing traumatic CSCI if they underwent decompression surgery before trauma. Conclusions Prophylactic surgical management for CSCS might not significantly affect the incidence of traumatic CSCI.

Efficacy of Cervical Expansive Laminoplasty for Quadriplegic Patients Without Cervical Bony Injury

STUDY DESIGN: Retrospective study. OBJECTIVES: To evaluate the efficacy of cervical expansive laminoplasty for patients with quadriplegia due to traumatic cervical spinal cord injury (SCI) without skeletal injury. SUMMARY OF LITERATURE REVIEW: There are a few studies on the surgical results for acute cervical SCI without bony injury. MATERIALS AND METHODS: From 2003 to 2010, among the patients who visited emergency room with post-traumatic quadriplegia, 12 patients who had underwent cervical expansive laminoplasty for acute cervical SCI without body injury and cord compression on MR images were included in this study. We evaluate the pre-operative swelling on MRI, the change of neurologic symptoms at pre-, post operative state, respiration state, complication and survival period. RESULTS: The average of motor index scores at the time of admission to the emergency room was 23 (4–30), and the average was changed to 29(4–43) during the follow-up period. No significant neurological improvement was observed in 11 cases except 1 case. The average time for operation after the injury was 26 hours(9–72). 4 patients showed paradoxical respiration when they first visited emergency room and the symptom continued after the operation and during follow-up periods. Another 4 patients showed paradoxical respiration after the operation. In all 8 cases who showed paradoxical respiration, tracheostomy and occasional ventilation were needed. In the follow-up period, 6 patients died due to respiratory failure within 1 year after the surgery. All these patients presented severe spinal cord edema on preoperative MRI with paradoxical respiration. CONCLUSIONS: Efficacy of expansive laminoplasty for quadriplegic patients due to acute cervical SCI without bony injury may be limited. In many patients, no significant neurological recovery was observed but it was clearly identified that prognosis was related to the grades of spinal cord edema and paradoxical respiration.

Results The operation time was (110.5+13.0) min, the amount of bleeding was (155.6+7.5)mL. Three patients developed hematoma compression, 13 patients developed high fever. All patients were cured after treatment and nursing. Conclusion Preoperative training of swallowing and blowing balloon is fundamental for ensured surgical effect and intraoperative surgical cooperation and close observation together with postoperative mental care, close obsersation and functional exercise are the guarantee for surgical effect.

The value of combined MRS and DWI in diagnosis of cervical cord injury / 实用放射学杂志

Objective To explore the value of MRS and DWI in diagnosis of cervical spinal cord injury.Methods The MRI plain scan images of 95 cases who suffering from cervical spinal cord injury were analyzed.They were divided into two groups according to the T2 signal of cervical cord,63 cases in Group A(incomplete injury group)with no abnormal on T2 ,32 cases in Group B(complete injury group)with high signal on T2 .The other 50 cases with no injury of cervical cord were recruited as control group (Group C). All the cases were performed with MRS and DWI.The N-acetyl aspartic acid(NAA),choline compounds(Cho)and creatine(Cr)as well as the peak area of lactic acid (Lac)on MRS,and apparent diffusion coefficient(ADC)on DTI were measured separately.Mean-while,NAA/Cho,NAA/Cr,Cho/Cr,Lac/Cho and ADC were analyzed.Results On MRS sequence,the values of NAA/Cho and NAA/Cr were lower in Group B (P <0.05)when compared with Group A.The values of NAA/Cho and NAA/Cr were also lower in Group B,when compared Group C.However,the value of Lac/Cho in Group B was higher than it in Group C(P <0.05).When com-pared Group A with Group C,the value of Lac/Cho only increased in the former.However,on DWI,the value of ADC in Group A was(0.79±0.1 7)×10 -3 mm2/s,lower than that of Group C(0.93±0.1 5)×10 -3 mm2/s (P =0.026);the value of ADC in Group B was(1.21±0.20)×10 -3 mm2/s,significantly higher than that of Group C(P =0.01 7).When compared with Group B,the value of ADC in Group A was a lightly lower (P =0.143)with no statistical significance.Conclusion MRS can noninvasively and quantita-tively reflect the changes of metabolism of medium in injured cervical cord and help characterize the severity and degree of cervical cord injury from metabolic and molecular level.DWI has high sensitivity on early diagnosis of cervical cord injury.The combination of MRS and DWI has important value for formulating reasonable treatment plan and prognostic evaluation.
