Point-of-care ultrasound (POCUS) is an essential component of emergency medicine, enabling rapid bedside assessment across a wide spectrum of acute conditions. Its effectiveness, however, remains constrained by operator dependency, variable image quality, and time-critical decision-making. Recent advances in artificial intelligence (AI) offer opportunities to augment POCUS by supporting image acquisition, interpretation, and quantitative analysis. This narrative review synthesizes current evidence on AI-enhanced POCUS applications in emergency care, encompassing trauma, non-traumatic emergencies, integrated workflows, resource-limited settings, and education and training. Across trauma settings, AI-assisted POCUS has demonstrated promising performance for automated detection of pneumothorax, hemothorax, and free intraperitoneal fluid, supporting standardized eFAST examinations and rapid triage. In non-traumatic emergencies, AI-enabled cardiovascular, pulmonary, and abdominal applications provide automated measurements and pattern recognition that can approach expert-level performance when image quality is adequate. Integrated AI–POCUS systems and educational tools further highlight the potential to expand ultrasound access, support non-expert users, and standardize training. Nevertheless, important limitations persist, including limited generalizability, dataset bias, device heterogeneity, and uncertain impact on clinical decision-making and patient outcomes. In conclusion, AI-enhanced POCUS is transitioning from proof-of-concept toward early clinical integration in emergency medicine. While current evidence supports its role as a decision-support tool that may enhance consistency and efficiency, widespread adoption will require prospective multicentre validation, development of representative POCUS-specific datasets, vendor-agnostic solutions, and alignment with clinical, ethical, and regulatory frameworks.

(1) Background: The perfusion index (PI) represents the ratio between pulsatile blood flow and non-pulsatile blood flow in the peripheral tissue. (2) We aimed to investigate the blood pressure perfusion of tissues and organs in ethnobotanical, synthetic cannabinoid and cannabis derivative consumers through the value of perfusion index. (3) Results: The patients enrolled were divided into two groups: group A, which included all patients who presented in the ED within the first three hours after consumption, and group B, which included those patients who presented more than three hours and up to 12 h after drug consumption. The average values of the PI in the case of group A/group B were 1.51 ± 1.07/4.55 ± 3.66. Statistically significant correlations in both groups were recorded between the drug intake ED admission, respiratory rate, peripheral blood oxygen saturation and tissue perfusion index (p < 0.001). The average value of the PI measured in group A was significantly lower compared to that measured in patients in group B. Therefore, we concluded that the perfusion of peripheral organs and tissues was lower in the first 3 h after drug administration. (4) Conclusions: PI plays an important role in the early detection of impaired organ perfusion and in monitoring tissue hypoxia. A decreased PI value may be an early indication of decreased perfusion organ damage.

Background/Objectives: Liver transplantation (LT) is often complicated by severe bleeding and coagulopathy. Viscoelastic testing (VET) offers real-time, bedside assessment of coagulation and may improve transfusion management compared to standard tests. This study evaluates the clinical impact of VET implementation during liver transplantation on bleeding, transfusion requirements, complications, and mortality in a single Eastern European tertiary transplant center. Methods: We conducted a single-center before-and-after study comparing patients undergoing LT before and after the implementation of VET. All procedures were performed by the same surgical and anesthetic team using a standardized protocol. Data were collected retrospectively for the Before VET group and prospectively for the After VET group. We compared transfusion requirements, bleeding, complications, and mortality. Results: A total of 59 patients were included, 22 in the After VET group and 37 in the Before VET group. VET implementation was associated with lower intraoperative blood loss (median 4000 mL vs. 6000 mL, p = 0.017) and reduced red blood cell (RBC) transfusion volume (670 mL vs. 1000 mL, p = 0.008). FFP (0.23 vs. 1.59 units, p = 0.007) and platelet use (0.68 vs. 1.81 units, p = 0.035) were also significantly lower in the VET group, while fibrinogen use was higher (3.00 g vs. 2.00 g, p = 0.036). No differences were observed in complication rates or mortality at 30 days and 1 year in this small before-and-after study. Conclusions: VET improved transfusion precision and individualized coagulation management during LT, leading to reduced use of blood products. These findings support the adoption of VET as a standard of care in LT protocols, as it may enhance patient safety, even though no differences in postoperative complications or mortality were observed.

Early bacterial infections (EBI) remain a major cause of morbidity and mortality after liver transplantation (LT). This study aimed to characterize their incidence, microbiological spectrum, risk factors, and clinical impact in an Eastern European cohort. We retrospectively analyzed 64 adult LT recipients from a tertiary center, focusing on perioperative parameters, infection profiles, and postoperative outcomes. EBI, defined as infections occurring within 30 days after transplantation and diagnosed according to CDC/NHSN criteria, occurred in 48.4% of patients. Gram-negative bacilli predominated (73.7%), mainly Pseudomonas aeruginosa (34.2%) and Klebsiella pneumoniae (15.8%), while Clostridioides difficile (CDI) accounted for 18.4% of confirmed cases diagnosed by stool toxin assay. Infected patients had greater intraoperative blood loss (median 6500 mL vs. 5000 mL, p = 0.036) and required more transfusions. The higher infection rate in our cohort may also be related to longer surgical duration. All deaths within the first postoperative year occurred among infected recipients, yet overall 30-day (7.8%) and 1-year (14.1%) mortality rates remained within the range reported internationally, suggesting that timely diagnosis and adequate management limited the impact of infections on survival. These findings emphasize the importance of infection prevention, optimized transfusion and bleeding control, and tailored antibiotic prophylaxis based on local microbiological patterns after LT.

Despite advancements in surgical and anesthetic techniques, significant bleeding remains a common challenge during orthotopic liver transplantation (OLT). The extensive nature of the surgical procedure, combined with the patient’s fragile coagulation profile, places individuals undergoing OLT at a high risk for massive hemorrhage (MH). Blood transfusions and hemostatic products are frequently required and can be life-saving. However, these resources are often limited, and their use may be associated with numerous complications. This study aimed to evaluate the impact of MH on the day of surgery on the outcomes of patients undergoing OLT from brain-dead donors at our institution. We conducted a retrospective single-center study including all adult patients who underwent OLT from brain-dead donors at the Emergency County Clinical Hospital “Saint Spiridon” in Iași. Preoperative circulating blood volume was calculated for each patient and compared with the estimated blood loss on the day of surgery. Patients who lost >1 circulating blood volume were classified as having experienced MH. The study population was divided into 2 groups: those with MH and those without. Outcomes were assessed based on 30-day and 1-year mortality, as well as medical and surgical complications. The study included 53 patients, with a median blood loss of 5500 mL (4650 mL). MH occurred in 26 patients (49.1%). Patients with a lower body mass index (24.3 vs 26.6, P = .028) and thrombocytopenia (55.5 vs 75 × 10³/µL, P = .04) were more likely to experience MH. Those with MH had higher rates of cardiovascular complications (38.5% vs 7.4%, P = .007), infectious complications (69.2% vs 37%, P = .009), and surgical reintervention (34.6% vs 11.1%, P = .04). Mortality rates at 30 days and 1 year did not significantly differ between patients with and without MH. MH adversely affects the outcomes of OLT patients, as evidenced by increased rates of cardiovascular and infectious complications and a higher likelihood of requiring surgical reintervention.
