Background Echocardiography in the setting of resuscitation can provide information as to the cause of the cardiac arrest, as well as indicators of futility. This systematic review and meta-analysis were performed to determine the value of point-of-care ultrasonography (PoCUS) in the assessment of survival for adult patients with cardiac arrest. Methods This meta-analysis was performed in adherence to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, EMBASE, Web of Science, Cochrane have been searched from databases inception until March 2 nd 2021. The search was limited to adult patients with cardiac arrest and without publication dates or country restrictions. Papers were chosen if they met the required criteria relating to the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of this diagnostic technique concerning resuscitation outcomes. Results This systematic review identified 20 studies. Overall, for survival to hospital discharge, PoCUS was 6.2% sensitivity (95% confidence interval [CI] 4.7–8.0%) and 2.1% specific (95% CI 0.8–4.2%). PoCUS sensitivity and specificity for return of spontaneous circulation were 23.8% (95% CI 21.4–26.4%) and 50.7% (95% CI 45.8–55.7%) respectively, and for survival to admission 13.8% (95% CI 12.2–15.5%) and 20.1% (95% CI 16.2–24.3%), respectively. Conclusions The results do not allow unambiguous recommendation of PoCUS as a predictor of resuscitation outcomes and further studies based on a large number of patients with full standardization of operators, their training and procedures performed were necessary.

“…The optic nerve is the second cranial nerve and is surrounded by the same sheath as the brain [2]. When intracranial pressure increases, the cerebrospinal fluid flows into the subarachnoid space causing an increase in pressure (enlarging the diameter) of the optic nerve [3]. Knowing this relationship, we can indirectly determine intracranial pressure (ICP) [4].…”

Ultrasonography is a diagnostic technique that has been used clinically for 30 years. Due to the increased availability of ultrasound machines as well as the reduction of their size and making them more mobile, ultrasound has found its place in early diagnosis in emergency medicine settings. One of the important, however, an underestimated ultrasound examination is the measurement of the thickness of the optic nerve sheath. The optic nerve is the second cranial nerve, meaning the same sheath surrounds it as the brain. At the moment of intracranial pressure increase, cerebrospinal fluid flows into the subarachnoid space causing an increase in intracranial pressure and thus increasing the diameter of the optic nerve sheath. therefore, ONSD imaging is a quick non-invasive test aimed at detecting and monitoring changes in intracranial pressure. Optic nerve sheath ultrasound is a simple, safe and inexpensive bedside diagnostic test. Ophthalmic ultrasound usually uses the frequency between 5 and 10.5 MHz to evaluate the eye and the orbit.

“…As mentioned previously, cardiac tamponade is a life-threatening condition and, in the event of intensification of symptoms, requires urgent intervention in the form of decompression of the pericardial sac. However, in order not to delay the tamponade diagnosis procedure, especially in patients with suspected/confirmed COVID-19, when medical staff wears full personal protective equipment for aerosol generating procedures (PPE AGP), ultrasonography may be helpful [6,7]. For this purpose, the Focus Assessment Transthoracic in Emergency (FATE) protocol can be used.…”
