Does Combined Anterior-Posterior Approach Improve Outcomes Compared with Posterioronly Approach in Traumatic Thoracolumbar Burst Fractures?: A Systematic Review

The aim of this systematic review was to evaluate the surgical, radiological, and functional outcomes of posterior-only versus combined anterior-posterior approaches in patients with traumatic thoracolumbar burst fractures. The ideal approach (anterior-only, posterior-only, or combined anterior-posterior) for the surgical management of thoracolumbar burst fracture remains controversial, with each approach having its advantages and disadvantages. A systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was performed (registration no., CRD42018115120). The authors reviewed comparative studies evaluating posterior-only approach compared with combined anterior-posterior approaches with respect to clinical, surgical, radiographic, and functional outcome measures. Five retrospective cohort studies were included. Postoperative neurological deterioration was not reported in either group. Operative time, estimated blood loss, and postoperative length of stay were increased among patients in the combined anterior-posterior group in one study and equivalent between groups in another study. No significant difference was observed between the two approaches with regards to long-term postoperative Cobb angle (mean difference, −0.2; 95% confidence interval, −5.2 to 4.8; p =0.936). Moreover, no significant difference in functional patient outcomes was observed in the 36item Short-Form Health Survey, Visual Analog Scale, and return-to-work rates between the two groups. The available evidence does not indicate improved clinical, radiologic (including kyphotic deformity), and functional outcomes in the combined anterior-posterior and posterior-only approaches in the management of traumatic thoracolumbar burst fractures. Further studies are required to ascertain if a subset of patients will benefit from a combined anterior-posterior approach.

Administration of tranexamic acid for victims of severe trauma within pre-hospital care ambulance services (PHCAS) in Malaysia

@#Introduction: Trauma is a Global threat and the 5th highest cause of all-cause mortality in Malaysia caused predominantly due to road traffic accidents. Majority of trauma victims are young adults aged between 21-40 years old. In Malaysia, 24 out of 100,000 population die annually due to trauma, rating us amongst the highest in South East Asia. These alarming figures justify aggressive preventive and mitigation strategies. The aim of this paper is to promote the implementation of evidence-based interventions that will reduce the rate of preventable death because of trauma. Tranexamic acid is one of the few interventions in the early management of severe trauma with level-one evidence. Tranexamic acid has been proven to reduce all causes of mortality and mortality due to bleeding. Evidence proves that it is most effective when administered early, particularly within the 1st hour of trauma. This proposed guideline is formulated based upon quality evidence from multicentre studies, clinical practices in other countries and consideration of the local demographic factors with the intent of enabling an easy and simple pathway to administer tranexamic acid early in the care of the severely injured. Conclusion: The guideline highlights select pre-hospital criteria’s and the methods for drug administration. The authors recognise that some variants may be present amongst certain institutions necessitating minor adaptations, nevertheless the core principles of advocating tranexamic acid early in the course of pre-hospital trauma should be adhered to.

Pulmonary distress following attempted suicidal hanging.

OBJECTIVE : To assess the incidence of post-hanging pulmonary distress in cases of attempted suicidal hanging and predictors of outcome among these patients. DESIGN : Five-year retrospective analysis. SETTING: Tertiary care center in south India. PATIENTS :A total of 335 patients who attempted suicidal hanging, aged above 16 years, were admitted during this period. Thirty-eight of them with pulmonary distress established clinically and with radiological evidence of pulmonary injury post hanging met the inclusion criteria. MEASUREMENTS : Data from ICU records of 5 years, X-rays and laboratory investigations were reviewed. In patients identified to have post-hanging pulmonary distress, the neurological status, chest x-rays, arterial blood gas values and outcome data were collected and analyzed. RESULTS : Eleven percent (n = 38) of the 335 patients admitted following attempted suicidal hanging were diagnosed to have post-hanging pulmonary distress. The overall mortality among post-hanging patients was 5%, which increased to 34.2% (n = 13) in the presence of pulmonary distress (P < or = 0.001). Among the prognostic factors evaluated, a PaO 2 / FiO 2 (P/F) ratio of < 100 at admission predicted a poor outcome (P < or = 0.001). CONCLUSION : Post-hanging pulmonary distress is a relatively common complication of hanging and is associated with increased mortality. P/F ratio from arterial blood gas at admission was the only significant predictor of outcome in this group of patients.
