Objectives. The aim of the study was to compare adductor canal block and femoral nerve block in the postoperative analgesia of patients undergoing elective arthroscopic knee surgery with respect to opioid use and Visual Analogue Scale (VAS), which is a unidimensional measurement of pain intensity. Methods. The study was designed and conducted prospectively between April 2016 and November 2016 in a tertiary care hospital but the results were evaluated retrospectively. Prior to the induction of general anesthesia for knee surgery, (the first) 20 consecutive patients underwent femoral nerve block, and (the second) 20 consecutive patients received adductor canal block. Patients receiving adductor canal block for analgesia were referred to as Group A and patients receiving femoral nerve block for analgesia were defined as Group F. Pain was evaluated using the VAS score.The results were compared statistically. Results. Both the femoral nerve block and adductor canal block groups showed similar results in terms of VAS and opioid use (p < 0.05). Conclusion. In the postoperative analgesia of patients undergoing elective arthroscopic knee surgery, no difference was found between adductor canal block and femoral nerve block in terms of opioid use and VAS scores.Eur Res J 2018

Background and Objective: Surgical procedures involving incisions of the chest wall regularly pose challenges for intra-and postoperative analgesia. For many decades, opioids have been widely administered to target both, acute and subsequent chronic incisional pain. Opioids are potent and highly addictive drugs that can provide sufficient pain relief, but simultaneously cause unwanted effects ranging from nausea, vomiting and constipation to respiratory depression, sedation and even death. Multimodal analgesia consists of the administration of two or more medications or analgesia techniques that act by different mechanisms for providing analgesia. Thus, multimodal analgesia aims to improve pain relief while reducing opioid requirements and opioid-related side effects. Regional anesthesia techniques are an important component of this approach.Methods: For this narrative review, authors summarized currently used regional anesthesia techniques and performed an extensive literature search to summarize specific current evidence. For this, related articles from January 1985 to March 2022 were taken from PubMed, Web of Science, Embase and Cochrane Library databases. Terms such as "pectoral nerve blocks", "serratus plane block", "erector spinae plane block" belonging to blocks used in thoracic surgery were searched in different combinations.

New-onset atrial fibrillation (NOAF) is one of the leading causes of morbidity and mortality, especially in older patients in the intensive care unit (ICU). Although many comorbidities are associated with NOAF, the effect of anemia on the onset of atrial fibrillation is still unknown. This study aimed to test the hypothesis that anemia is associated with an increased risk of developing NOAF in critically ill patients in intensive care. We performed a retrospective analysis of critically ill patients who underwent routine hemoglobin and electrocardiography monitoring in the ICU. Receiver operating characteristics analysis determined the hemoglobin (Hb) value that triggered NOAF formation. Bivariate correlation was used to determine the relationship between anemia and NOAF. The incidence of NOAF was 9.9% in the total population, and 12.8% in the patient group with anemia. Analysis of 1931 patients revealed a negative association between anemia and the development of NOAF in the ICU. The stimulatory Hb cut-off value for the formation of NOAF was determined as 9.64 g/dL. Anemia is associated with the development of NOAF in critically ill patients in intensive care.
