Background:Patients require procedural sedation and analgesia (PSA) for the treatment of acute traumatic injuries. PSA has complications. Ultrasound (US) guided peripheral nerve block is a safe alternative.Aim:Ultrasound guided nerve blocks for management of traumatic limb emergencies in Emergency Department (ED).Setting and Design:Prospective observational study conducted in ED.Materials and Methods:Patients above five years requiring analgesia for management of limb emergencies were recruited. Emergency Physicians trained in US guided nerve blocks performed the procedure.Statistical analysis:Effectiveness of pain control, using visual analogue scale was assessed at baseline and at 15 and 60 minutes after the procedure. Paired t test was used for comparison.Results:Fifty US guided nerve blocks were sciatic- 4 (8%), femoral-7 (14%), brachial- 29 (58%), median -6 (12%), and radial 2 (4%) nerves. No patients required rescue PSA. Initial median VAS score was 9 (Inter Quartile Range [IQR] 7-10) and at 1 hour was 2(IQR 0-4). Median reduction in VAS score was 7.44 (IQR 8-10(75%), 1-2(25%) (P=0.0001). Median procedure time was 9 minutes (IQR 3, 12 minutes) and median time to reduction of pain was 5 minutes (IQR 1,15 minutes). No immediate or late complications noticed at 3 months.Conclusion:Ultrasound-guided nerve blocks can be safely and effectively performed for upper and lower limb emergencies by emergency physicians with adequate training.
Introduction:Airway and breathing management play critical role in trauma resuscitation. Early identification of esophageal intubation and detection of fatal events is critical. Authors studied the utility of integration of point-of-care ultrasound (POCUS) during different phases of rapid sequence intubation (RSI) in trauma resuscitation.Methods:It was prospective, randomized single-centered study conducted at the Emergency Department of a level one trauma center. Patients were divided into ultrasonography (USG) and clinical examination (CE) arm. The objectives were to study the utility of POCUS in endotracheal tube placement and confirmations and identification of potentially fatal conditions as tracheal injury, midline vessels, paratracheal hematoma, vocal cord pathology, pneumothorax, and others during RSI. Patient >1 year of age were included. Time taken for procedure, number of incorrect intubations, and pathologies detected were noted. The data were collected in Microsoft Excel spread sheets and analyzed using Stata (version 11.2, Stata Corp, Texas, U. S. A) software.Results:One hundred and six patients were recruited. The mean time for primary survey USG versus CE arm was (20 ± 10.01 vs. 18 ± 11.03) seconds. USG detected four pneumothorax, one tracheal injury, and one paratracheal hematoma. The mean procedure time USG versus CE arm was (37.3 ± 21.92 vs. 58 ± 32.04) seconds. Eight esophageal intubations were identified in USG arm by POCUS and two in CE arm by EtCO2 values.Conclusion:Integration of POCUS was useful in all three phases of RSI. It identified paratracheal hematoma, tracheal injury, and pneumothorax. It also identified esophageal intubation and confirmed main stem tracheal intubation in less time compared to five-point auscultation and capnography.
Objective The objective of this study was to describe the lung sonographic findings of COVID-19 patients prospectively and investigate its association with disease severity. Methods This study was conducted in an emergency department and included consecutively enrolled laboratory confirmed COVID-19 patients. Lung sonography findings were described in all the included patients and analysed with respect to the clinical severity of the patients. Results 106 patients were included in the study. Common sonographic findings in COVID-19 patients were pleural line irregularity or shredding (70% of patients), followed by B – profile (59%), pleural line thickening (33%), occasional B – lines (26%), sub-pleural consolidations (35%), deep consolidations (6%), spared areas (13%), confluent B – lines or waterfall sign (14%) and pleural effusion (9%). These findings tended to be present more bilaterally and in lower lung zones. Sonographic characteristics like bilateral lung involvement, B – profile, spared areas and confluent B – lines or waterfall sign were significantly associated ( p < 0.01) with clinical severity (more frequent with increasing disease severity). Conclusion The lung sonographic findings of COVID-19 were found more bilaterally and in lower lung zones, and specific findings like B – profile, pleural thickening, spared areas and confluent B – lines or waterfall sign were associated with severe COVID-19.
Background:Focused assessment with sonography for trauma (FAST) is an important skill during trauma resuscitation. Use of point of care ultrasound among the trauma team working in emergency care settings is lacking in India.Objective:To determine the accuracy of FAST done by nonradiologists (NR) when compared to radiologists during primary survey of trauma victims in the emergency department of a level 1 trauma center in India.Materials and Methods:A prospective study was done during primary survey of resuscitation of nonconsecutive patients in the resuscitation bay. The study subjects included NR such as one consultant emergency medicine, two medicine residents, one orthopedic resident and one surgery resident working as trauma team. These subjects underwent training at 3-day workshop on emergency sonography and performed 20 supervised positive and negative scans for free fluid. The FAST scans were first performed by NR and then by radiology residents (RR). The performers were blinded to each other's sonography findings. Computed tomography (CT) and laparotomy findings were used as gold standard whichever was feasible. Results were compared between both the groups. Intraobserver variability among NR and RR were noted.Results:Out of 150 scans 144 scans were analyzed. Mean age of the patients was 28 [1-70] years. Out of 24 true positive patients 18 underwent CT scan and exploratory laparotomies were done in six patients. Sensitivity of FAST done by NR and RR were 100% and 95.6% and specificity was 97.5% in both groups. Positive predictive value among NR and RR were 88.8%, 88.46% and negative predictive value were 97.5% and 99.15%. Intraobserver performance variation ranged from 87 to 97%.Conclusion:FAST performed by NRs is accurate during initial trauma resuscitation in the emergency department of a level 1 trauma center in India.
