Background: Delivering early diagnosis of shock in resource-limited setting is challenging, especially with limited availability of point-of-care laboratory and radiological diagnostic facilities. There is growing urgency to provide point-of-care diagnosis and treatment for time-sensitive condition like shock.
Aims: We tried to evaluate the application of point-of-care ultrasound (Rapid Ultrasound for Shock and Hypertension [RUSH] protocol) considering different disease cohort and practice realities in our setup.
Settings And Design: This study was a single-center prospective diagnostic study to check the diagnostic accuracy of point-of-care ultrasound (RUSH protocol). This study was approved by the ethics committee.
Materials And Methods: The study was conducted at the emergency medicine department of a tertiary care government hospital in Central Gujarat from November 16 to October 17. All adult patients with clinical features of shock with systolic blood pressure <90 mmHg and shock index >1 presenting to emergency department were included as participants. The results of point-of-care ultrasound (RUSH protocol) were compared with the diagnosis given by consultants of respective department as per standard departmental practices.
Statistical Analysis And Results: A total of 130 patients were enrolled in this study. Mean time taken to examine by the point-of-care Ultrasound (RUSH protocol) was 12 min (range 11-14 min). Kappa index was 0.860. This protocol was able to correctly diagnose 100% of obstructive shock, 96.3% of cardiogenic shock, 94.4% of hypovolemic shock, 80.9% of mixed type of shock, and 75% of distributive type of shock.
Conclusion: This study highlights the role of point-of-care ultrasound (RUSH protocol) for early diagnosis of the shock etiology in emergency medicine department. Diagnosis using point-of-care ultrasound (RUSH protocol) significantly agreed with medical diagnosis. It showed good efficacy of point-of-care ultrasound (RUSH protocol) to differentiate causes of shock with good accuracy except distributive shock.

Objectives: To evaluate general practitioners' (GPs') ability to perform focused lung ultrasound (FLUS) following a training program and assess FLUS feasibility in general practice. Also, to describe FLUS findings and evaluate GPs' ability to interpret these in adults with acute lower respiratory tract infection (LRTI) when pneumonia is suspected and assess GPs' perception of FLUS impact.
Methods: Nine GPs, using point-of-care ultrasound, completed a FLUS training program.

is an intracellular parasite capable of crossing the placenta in pregnancy and infecting the developing fetus, leading to various congenital anomalies and even abortion. Acute infection is responsible for almost all cases of congenital toxoplasmosis in immunocompetent pregnant women. Prenatal screening for acute toxoplasmosis primarily involves maternal serology and fetal ultrasound imaging.

Background: Acute kidney injury (AKI) occurs in up to 50% of cardiac surgical patients and is often hemodynamically mediated. Point-of-care ultrasound is a non-invasive tool that has the potential to characterize intrarenal hemodynamics and predict the risk of AKI.
Objectives: We aimed to determine the predictive characteristics of intrarenal arterial and venous Doppler markers for postoperative AKI in cardiac surgical patients.

A time-sensitive, sight-threatening ocular condition presenting at an emergency department can be safely diagnosed promptly by ocular ultrasonography (OUS). OUS is a quick, safe, and portable option for assessing severe tissue damage to the periorbital area. OUS can help identify patients who need immediate ophthalmology consultation in a busy setting or when direct ophthalmic examination is unavailable.
