This article discusses a cadaveric study comparing different ultrasound-guided approaches to brachial plexus blocks. The study evaluates needle visibility, anatomical structures, and local anesthetic diffusion. The results indicate that all approaches were effective, with the out-of-plane approach performing the best. The subclavian approach is highlighted as a new technique that improves visualization and reduces complications. However, the study's limitations include the use of cadavers and subjective evaluations. Authored by Maria Perez Herrero, Ece Altinpulluk, Mario Perez, Carlos Zamorano, Luis Vilches, and Felice Galluccio, this report provides a comprehensive analysis of the topic, offering diverse perspectives and culturally sensitive information. It is a valuable resource for library patrons conducting research on this subject. [Extracted from the article]

To evaluate superficial serratus anterior plane block's efficacy and side effects in preventing postoperative pain after breast cancer surgery. A prospective cohort study was conducted on 195 adult patients undergoing breast oncological surgery under general anesthesia (Group G, n = 96) or combined general anesthesia with superficial serratus anterior plane block (Group L, n = 99). Validated preoperative data, which are predictors of chronic postoperative pain of patients, were recorded (type of surgery, age, pain in the area of the intervention and the other regions; anesthetic-surgical data, analgesic doses used, duration of surgery; pain intensity (EVN scale) at immediate postoperative period, 24 h, seven days and one month after the surgery, and complications. Pain intensity, measured by the EVN scale, had a mean of 1.02 +/− 1.656 in the Postoperative Unit; 1.20 +/− 1.448 at 24 h; 0.76 +/− 1208 seven days; and 0.34 +/− 0.757 one month after surgery. Patients were operated under general anesthesia (n = 96) or general anesthesia combined with the interfascial block (n = 99). Significant differences (p < 0.05) were found in age, height, and VAS scale in PACU. Ten complications were recorded, six in Group L and four in Group G. There were no differences between groups in complications. Superficial serratus anterior plane blocks are effective and safe in pain control in the immediate postoperative period for breast cancer surgery as a part of the multimodal approach. No significant differences were found one week and one month after surgery. • Serratus anterior block is used in clinical practice. The efficacy and side effects remain understudied. • Analgesic interfascial blockades provide significative analgesia in the immediate postoperative period • No complications associated with the analgesic technique were recorded.

The pandemic of COVID-19 requires rapid and easy access to reliable imaging modalities for diagnosis and follow up. Considering the cost-effectiveness of the imaging used, ultrasound is a non-ionizing, portable and bedside imaging modality with a high diagnostic impact in emergencies and intensive care units in pandemics, but it is operator dependent. In our article, we provide a comprehensive review of the role of point-of-care ultrasound in the diagnosis of COVID-19 infection and its impact on the lungs, cardiovascular system, eyes and abdominal organs. Moreover, ultrasound can provide real-time diagnostic and therapeutic interventions, such as the placement of a central catheter and aspiration of pericardial effusion. Awareness of health care professionals in the front-line fighting COVID-19 infection in emergency rooms, clinics, and in intensive care units is important and will help rapid and targeted management decisions.
