Comparative Study
Motion resistance in peripheral oxygen saturation monitoring using Biolight Analog SpO2 compared to Masimo SpO2: a non-inferiority study.
Pulse oximeters are vital for assessing blood oxygen levels but can produce inaccurate readings during patient motion, leading to false alarms and alarm fatigue. Analog SpO2 Technology, which uses analog waveforms to filter motion artifacts, may improve accuracy compared to digital sensors. However, the effectiveness of this technology in reducing false alarms in clinical settings remains unclear. This study assesses and compares the motion resistance of Analog SpO2 Technology of two devices in the market. ⋯ Analog SpO2 exhibited motion resistance under static, linear and continuous waving angular motion up to 120 bpm and 160 bpm, but alarms occurred at 160 bpm with continuous tapping angular motion. These findings signify non-inferiority of either device in clinical settings. Further studies should include patients with cardiovascular and/or respiratory diseases.

Randomized Controlled Trial
Efficacy of Pericapsular Nerve Group (PENG) block in preoperative rehabilitation (Prehabilitation) for patients with femoral neck fractures: study protocol for a randomized, placebo-controlled, double-blinded trial.
Despite surgery intervention for femoral neck fractures is recommended within 48 h of admission, achieving timely surgery presents challenges for patients with severe comorbidities, or in resource-limited settings. Preoperative rehabilitation (prehabilitation) reduces bedridden time, enhances mobility, and improves postoperative outcomes for patients scheduled for hip arthroplasty due to femoral neck fractures. However, prehabilitation is hindered by insufficient pain control. The pericapsular nerve group (PENG) block provides effective analgesia while preserving motor function. We designed a study to assess the efficacy of PENG block in facilitating prehabilitation for patients with femoral neck fractures who are scheduled for hip arthroplasty. ⋯ This is the first study aiming to assess the efficacy of PENG block in prehabilitation for patients with femoral neck fractures who are scheduled for hip arthroplasty. PENG block could be beneficial, especially for patients facing delayed surgery, providing a potential treatment option during the waiting period.

Randomized Controlled Trial Comparative Study
Effect of Atracurium versus Cisatracurium on QT interval changes in patients undergoing cataract surgery: a randomized clinical trial.
Muscle relaxants are used during surgery, but their impact on ECG may differ, potentially affecting cardiac safety. This study aimed to compare the effects of Atracurium versus Cisatracurium on QT interval changes in patients undergoing cataract surgery. ⋯ Atracurium causes more QT prolongation than Cisatracurium. While both affect QTc intervals, Cisatracurium has a more stable impact on cardiac repolarization, making it safer for patients at risk of QT prolongation. Cisatracurium's minimal impact on cardiovascular function, especially in patients with low ejection fraction, makes it the preferred choice for maintaining cardiac stability.

To explore whether monitored anesthesia care is more beneficial to the outcome of transcatheter aortic valve implantation. ⋯ Monitored anesthesia care has an absolute advantage in patient survival and effectively shortens the length of hospitalization. In addition, it also reduces the risk of complications such as paravalvular leakage and stroke. Monitoring care under anesthesia plays a vital role during TAVI surgery, not only helping to ensure the smooth progress of the surgery and patient safety, but also promoting the patient's recovery and recovery.

Review Case Reports
Inferior vena cava thrombosis in patients undergoing extracorporeal membrane oxygenation: a case series and literature review.
Extracorporeal membrane oxygenation (ECMO) is mainly used for support of patients with cardiopulmonary collapse. The increasing use of ECMO has shown promising outcomes; however, it still carries the risk of significant complications. Inferior vena cava (IVC) thrombosis is an underestimated complication. ⋯ Factors such as elevated CRP and PCT levels, low aPTT levels, and the use of VA ECMO may contribute to the development of ECMO-related IVC thrombosis. Monitoring of anticoagulation with aPTT alone or in combination with ACT during ECMO may have inherent limitations. Anticoagulation alone may be an effective treatment for IVC thrombosis.
