Value of focused assessment with sonography for trauma in management of hypotensive polytrauma patients– A Meta-analysis

Abstract

Abstract Background Severe or major trauma is a worldwide pandemic and one of the leading causes of death and disability. Polytrauma always involves young, productive individuals and represents a substantial burden on the society Management of Trauma injuries generally emphasizes the importance of identifying and prioritizing the most serious life-threatening injuries and managing them. Management consists of a rapid primary survey, resuscitation of vital functions, a more detailed secondary survey, and, finally, the initiation of definitive care. Damage-control surgery has increasing role as it proves reliability in the most sensitive situations. Objective To assess the Value of focused assessment with sonography for management of hypotensive polytrauma patients. Patients and Methods: All trials about the usage include participants who came to ER due to polytrauma with blunt or penetrating abdominal trauma or with undifferentiated shock, randomized controlled trials and prospective or retrospective cohort studies that assess the value of focused sonography in hypotensive polytrauma patients. Results The value of an odds ratio like that of other measures of test performance for example sensitivity and specificity and likelihood ratios depends on prevelance. For example, a test with pooled diagnostic odds ratio of 10.00 is considered to be very good by current standards, therefore pooled diagnostic odds ratio of 77.46 which is considered to be very good. Spearman correlation coefficient:-0.429 with p value 0.397 which is insignificant so, there was low threshold effect Positive and negative Likelihood ratio both are done on six studies with positive likelihood ratio is 21.27 and negative likelihood ratio is 0.29 sensitivity and specificity are done on the six studies with pooled sensitivity is 0.73 and pooled specificity is 0.98. Data Sources: Medline databases (PubMed, Medscape, ScienceDirect. EMF-Portal) and all materials available in the Internet till 2022. Conclusion FAST is significant in polytrauma patients especially in hypotensive patients with considerable accuracy rate 77.46 and good pooled sensitivity with 0.73 and pooled specificity with 0.98 and good ROC curve with are under the curve 0.70.
