Fascial plane blocks are becoming popular as useful and safe methods to provide pain relief. While their use in thoracic and abdominal surgery is well known, their application in upper arm surgery and trauma is underscored. This review explores research from the last 10 years focusing the use of fascial plane blocks to relieve pain after surgery or trauma in the upper limb. Studies include randomized controlled trials, observational studies, and case reports. They look at techniques like the cervical and high-thoracic erector spinae plane (ESP) block, the clavipectoral fascia plane (CFP) block, the superior posterior serratus intercostal plane (SPSIP) block, and periarticular approaches like the pericapsular (PENG) shoulder block. The high-thoracic ESP block provided pain relief and was often given with a continuous catheter infusion. The research shows that there is a tendency toward combining fascial blocks with each other or with peripheral nerve blocks to cover more area and cut down on the use of opioids. Even if the results are promising, there aren't many randomized trials in the literature, thus data are still mostly low-quality level. Risk of potential complications, such as local anesthetic systemic toxicity (LAST) or unintentional dissemination to important anatomical areas, exists although not reported. This study shows how fascial plane blocks in upper limb surgery are changing and recommends for more high-quality research to find out when they are best used, how safe they are, and how well they may work.

Background
Acute kidney injury (AKI) is a common complication after coronary artery bypass grafting (CABG), associated with adverse short- and long-term outcomes. Sodium-glucose cotransporter-2 inhibitors (SGLT2i) have been shown to reduce occurrence of AKI in several populations, yet their perioperative effects in patients undergoing CABG are unknown.
Methods
We conducted a retrospective study at the Department of Cardiac Surgery, Medical University of Graz (2020–2024) to evaluate the impact of preoperative SGLT2i use on cardiac surgery–associated AKI in adults undergoing urgent or emergent isolated coronary artery bypass grafting in patients with an indication for SGLT2i therapy (type 2 diabetes mellitus, heart failure with reduced ejection fraction, or chronic kidney disease). Patients with preoperative dialysis, sepsis, reoperation, mechanical circulatory support or missing laboratory data were excluded. Exposure was defined as SGLT2i use within two weeks before surgery, and the primary outcome was cardiac surgery-associated AKI (CSA-AKI) according to KDIGO criteria. Secondary outcomes included kidney replacement therapy, ICU length of stay, 30-day mortality and postoperative diabetic ketoacidosis. Causal effects were estimated using entropy balancing. Results were reported as weighted risk differences, risk ratios, and adjusted mean differences, with time-to-event outcomes analyzed via weighted Cox models and Kaplan–Meier estimates.
Results
Among 484 patients, 135 were on SGLT2i. CSA-AKI occurred in 23.0 % of SGLT2i users vs. 28.1 % of non-users (risk ratio of 0.63 [95 % CI 0.44–0.91; p = 0.014]). The association was pronounced in patients with heart failure with reduced ejection fraction and those with high EuroSCORE II. No differences were observed in other secondary endpoints and no cases of postoperative diabetic ketoacidosis occurred.
Conclusion
Preoperative SGLT2i use was associated with a significantly lower risk of CSA-AKI in patients undergoing urgent or emergent CABG. These findings need to be confirmed in prospective multicenter trials but underline the favorable safety profile of this medication.
背景:急性肾损伤(AKI)是冠状动脉旁路移植术(CABG)后常见的并发症,与不良的短期和长期预后相关。钠-葡萄糖共转运蛋白-2抑制剂(SGLT2i)已被证明可以减少几个人群AKI的发生,但其在CABG患者的围手术期效果尚不清楚。方法:我们在格拉茨医科大学心脏外科(2020-2024)进行了一项回顾性研究,以评估术前使用SGLT2i对有SGLT2i治疗指征(2型糖尿病、心力衰竭伴射血分数降低或慢性肾病)的成人紧急或紧急孤立冠状动脉旁路移植术中心脏手术相关AKI的影响。排除术前透析、败血症、再手术、机械循环支持或缺少实验室数据的患者。暴露被定义为术前两周内使用SGLT2i,根据KDIGO标准,主要结局是心脏手术相关AKI (CSA-AKI)。次要结局包括肾脏替代治疗、ICU住院时间、30天死亡率和术后糖尿病酮症酸中毒。利用熵平衡估计因果效应。结果报告为加权风险差异、风险比和调整后的平均差异,并通过加权Cox模型和Kaplan-Meier估计分析事件发生时间。结果:484例患者中,有135例接受SGLT2i治疗。SGLT2i使用者中CSA-AKI发生率为23.0%,非使用者中为28.1%(风险比为0.63 [95% CI 0.44-0.91; p = 0.014])。在射血分数降低的心力衰竭患者和EuroSCORE II高的患者中,这种关联明显。其他次要终点无差异,术后无糖尿病酮症酸中毒病例发生。结论:术前使用SGLT2i与急诊或紧急冠脉搭桥患者CSA-AKI风险显著降低相关。这些发现需要在前瞻性多中心试验中得到证实,但强调了该药物的良好安全性。

Acute intracranial injuries including subarachnoid hemorrhage, traumatic brain injury, stroke, and seizures often trigger cardiovascular and pulmonary complications through the neurocardiac axis. This bidirectional connection between the brain and the heart is mediated by sympathetic overactivity, catecholamine excess, autonomic imbalance, and systemic inflammation. This narrative review synthesizes current evidence published between 1968 and 2025, identified through a comprehensive literature search. Representative studies were selected to provide an integrative overview of neurocardiac complications in acute neurologic injury, focusing on underlying mechanisms, clinical manifestations, diagnostic challenges, and management strategies. We describe the mechanisms underlying neurogenic stunned myocardium and Takotsubo syndrome, highlighting regional vulnerability based on autonomic innervation. Electrocardiographic features, cardiac biomarkers, and echocardiographic findings are discussed in the context of early recognition and risk stratification. We further examine diagnostic challenges, the importance of distinguishing neurologic from primary cardiac pathology, and therapeutic approaches including autonomic modulation and cardiopulmonary protective strategies. Understanding the unique pathogenesis of these syndromes can help guide individualized treatment strategies and anesthetic management to improve outcomes in patients with acute neurologic injury. By consolidating multidisciplinary insights, this review aims to enhance recognition and management of neurocardiac complications in this population.

Despite advances in perioperative medicine, variability in patient responses to commonly administered anesthetic and analgesic agents remains a clinical challenge. Genetic factors are increasingly proposed contributors to these interindividual differences, yet much of the supporting evidence remains preliminary, heterogeneous or insufficiently validated. Pharmacogenetics has emerged as a promising field to improve therapeutic precision. However, its clinical application in perioperative care remains limited. This narrative review critically appraises pharmacokinetic and pharmacodynamic drug–gene interactions that influence responses to routinely administered agents. Genetic variations affect multiple aspects of perioperative care, including drug metabolism and receptor sensitivity, pain processing, autonomic function, and susceptibility to complications such as postoperative nausea and vomiting and opioid-induced respiratory depression. A better understanding of drug–gene interactions may help anesthesiologists identify patients with atypical sensitivity or resistance to commonly used agents, as well as those at increased risk for perioperative complications. Integration of pharmacogenetic data into perioperative decision-making may facilitate individualized care, but broader implementation will require replication in diverse cohorts, prospective clinical validation and development of evidence-based guidelines.

Background
Preoperative oral carbohydrate loading is thought to reduce postoperative nausea and vomiting (PONV). However, it is unknown if the benefit of carbohydrate loading is maintained in the presence of total intravenous anaesthesia (TIVA). The aim of this systematic review was to determine whether oral carbohydrate loading reduced PONV compared to overnight fasting between adult elective surgery patients receiving TIVA or inhalational general anaesthesia.
Methods
A search of seven databases was conducted until March 2024. Randomised controlled trials conducted with patient aged 18 years or older were included. Two reviewers independently screened titles, abstracts and full texts, and assessed risk of bias using the Cochrane ROB-2 Tool. Study data was pooled using random effects meta-analyses.
Results
We included 26 studies in this review, and 25 in the meta-analyses (n = 2491). Preoperative oral carbohydrate loading reduced the overall risk (log RR: –0.35, 95 % CI: −0.62 to −0.08, I2 = 51.11 %) and severity (SMD: -0.46, 95 % CI: −0.68 to −0.24, I2 = 62.09 %) of PONV, and pain severity (MD: -0.69, 95 % CI: −1.13 to −0.25, I2 = 83.98 %) compared to prolonged fasting when pooled across both anaesthesia approaches. The risk of PONV was reduced in patients receiving inhalational anaesthesia, but not in those receiving TIVA, while the reduction in severity was more significant in TIVA.
Conclusion
Oral carbohydrate loading reduces the severity of PONV and pain, regardless of the anaesthesia approach, compared to prolonged fasting. These findings support the clinical advantages of oral carbohydrate loading for postoperative outcomes, regardless of anaesthesia approach.

Background
The use of quantitative neuromuscular monitoring during induction of anesthesia to establish a baseline neuromuscular response and ensure paralysis of the vocal cords during laryngoscopy and tracheal intubation has yet to become standard practice. The current study compared intubating conditions based on quantitative measurements (train-of-four count) with intubating conditions based on the time since rocuronium administration.
Methods
Consenting adult patients undergoing general anesthesia requiring neuromuscular block were randomized into 2 groups. Following placement of a quantitative electromyographic neuromuscular monitor, general anesthesia was induced with propofol 1–1.5 mg/kg followed by rocuronium 0.6 mg/kg. In one group, intubation commenced 2 min after rocuronium administration (Time Group). In the other, intubation commenced when the first train-of-four (TOF) count was ≤1 (Count Group). Video laryngoscopy was used in both groups and the intubating conditions were noted. A Wilcoxon rank sum test or Fisher's exact test was used to compare intubating conditions between the 2 groups. Spearman's rank correlation test was used to describe the relationship between intubation conditions and the ratio of the amplitude of the first twitch of the TOF sequence, T1, to the control T1 amplitude (T1/Tc).
Results
There were 84 patients in the Count Group and 83 in the Time Group. More patients had ideal intubating conditions (relaxed jaw, abducted vocal cords, and no response to tracheal intubation) in the Count Group (61/84, 73 %) than the Time Group (47/83, 57 %, P = 0.036). The mean composite intubating score was better (lower) in the Count Group than in the Time Group (3.5 vs. 3.9, respectively, P = 0.016). The T1/Tc at intubation correlated with the composite intubating conditions score (Spearman's ρ = 0.34, P < 0.001).
Conclusion
Intubating conditions were better when the timing of intubation was guided by quantitative neuromuscular monitoring to ensure a TOF count ≤1 versus waiting a fixed time interval of 2 min following administration of rocuronium.
