Background: The Bispectral Index (BIS) and the Patient State Index (PSI) are commonly used measures to assess intraoperative sedation depth. However, model differences lead to different results, which in turn interferes with clinicians' judgment on the depth of anesthesia. Remimazolam tosilate (RT) for injection is a new benzodiazepine used in sedation.

How to better predict difficult airway and make corresponding preparations to reduce the occurrence of accidents is a difficult task faced by anesthesiologists every day. This study decide to evaluate the value of the Upper Lip Bite Test (ULBT) and the Modified Mallampati Test (MMT) in predicting difficult intubation under direct laryngoscopy and find out the most intuitive and simple method to predict difficult intubation under direct laryngoscopy in apparently normal patients.

Such movement may cause unnecessary problems. Currently, there is an increasing number of drugs for preventing etomidate-induced myoclonus (EM).

Here, we intend to determine diagnosis-valuable biomarkers for PAH and decode the fundamental mechanisms of the biological function of these markers. Two mRNA microarray profiles (GSE70456 and GSE117261) and two microRNA microarray profiles (GSE55427 and GSE67597) were mined from the Gene Expression Omnibus platform.

However, studies providing PAH-related gene expression profiles are scarce. To identify hub genes involved in PAH, we investigate two microarray data sets from gene expression omnibus (GEO).

As a result GPCCs often remain undiagnosed until surgery and therefore the surgical team face a greater challenge in perioperative management. The present study describes the case of a 36 year-old woman with an undiagnosed GPCC, which was successfully resected despite the occurrence of perioperative cardiovascular events, including hypertension, hypotension, ventricular arrhythmias, acute heart failure, acute myocardial infarction, and the patient was discharged home without any recurrence.

Previous studies have revealed that lidocaine exhibits antibacterial actions; regulating inflammatory responses, reducing postoperative pain and affecting the duration spent in hospital. Thus, the present study hypothesized that lidocaine may exert a protective effect on the CMI of patients undergoing surgery for the removal of a primary tumor.

However, previous studies have shown that dexmedetomidine delays recovery from propofol-remifentanil anesthesia. This study aimed to determine whether doxapram may hasten the recovery following dexmedotomidine-propofol-remifentanil anesthesia.

HMGB1 as a later inflammatory cytokines and a critical mediator of severe sepsis is always associated with the aggravation of organ failure. Previous study shows that lidocaine can inhibit the expression of HMGB1 in macrophage of septic rats and protect animals from organ failure.

Flurbiprofen has been suggested to alleviate cerebral ischemia/reperfusion injury in both focal and global cerebral ischemia models, but the mechanisms underlying the protective action are still incompletely understood. In this study we want to investigate the protective effect of flurbiprofen after transient middle cerebral artery occlusion (MCAO) in rats and the role of the NF-κB signaling pathway on this neuroprotective effect.

In this study we sought to determine whether HMGB1 is involved in the remodeling of pulmonary artery and investigate the mechanism. A rat model of pulmonary artery remodeling was successful induced with LPS infusion and the increasing of pulmonary arteries media was obviously inhibited in rats treated with thrice inject of HMGB1 neutralizing antibody.

However, it is unknown whether lidocaine has effects on high mobility group box 1 (HMGB1), a key mediator of inflammation.
View Article and Find Full Text PDFBackground: High mobility group box 1 (HMGB1), a key mediator of inflammation, has been shown to inhibit phagocytosis of apoptotic cells in sepsis. Lidocaine has been proven to protect macrophages in mice with septic peritonitis by attenuating the production of cytokines. However, it is currently unknown whether lidocaine also affects HMGB1.
