A relatively high dose of intraoperative remifentanil enhances periincisional hyperalgesia. Intraoperative MgSO(4) prevents remifentanil-induced hyperalgesia. However, hyperalgesia did not reach clinical relevance in terms of postoperative pain or analgesic consumption in patients undergoing thyroidectomy.

OBJECTIVES: In this randomized-controlled study, we investigated the effects of combined administration of pregabalin and dexamethasone on postoperative pain and analgesic requirements, and functional outcome in patients who underwent lumbar spinal surgery. METHODS: One hundred eight patients were randomized to group C (placebo+placebo), group P (pregabalin + placebo), or group PD (pregabalin+dexamethasone). According to their allocated group, patients received placebo or pregabalin 150 mg every

We investigated whether combined dexamethasone and ondansetron is more effective than ondansetron alone in preventing postoperative nausea and vomiting in patients with fentanyl-based intravenous patient-controlled analgesia. One hundred and thirty patients undergoing video-assisted thoracoscopic surgery were assigned to either an ondansetron group or a dexamethasone and ondansetron group. In all patients, ondansetron 4 mg was administered at the end of surgery and 12 mg was added to the patient

After briefly discussing endothelial glycocalyx and its role in vascular physiology and renal disease, this overview focuses on its degradation very early in the course of microbial sepsis. We describe our recently proposed mechanism for glycocalyx degradation induced by exocytosis of lysosome-related organelles and release of their cargo. Notably, an intermediate in nitric oxide synthesis, NG-hydroxy-l-arginine, shows efficacy in curtailing exocytosis of these organelles and improvement in anim

BACKGROUND: Perioperative cerebral hypoperfusion/ischemia is a major inciting factor of postoperative delirium, which is coupled with adverse outcome in elderly patients. Cerebral oximetry enables noninvasive assessment of the regional cerebral oxygen saturation (rSO2). This study aimed to investigate whether perioperative rSO2 variations were linked to delirium in elderly patients after spinal surgery. MATERIALS AND METHODS: Postoperative delirium was assessed for 48 hours postsurgery in 109 pa

In contrast to plasmalyte, fluid therapy with 0.9% saline resulted in transient hyperchloremic acidosis in patients undergoing multi-level lumbar spinal fusion, while coagulation assessed by ROTEM analysis and the amount of blood loss were similar between the groups.

The endothelial glycocalyx (EG) is a gel-like layer lining the luminal surface of healthy vascular endothelium. Recently, the EG has gained extensive interest as a crucial regulator of endothelial funtction, including vascular permeability, mechanotransduction, and the interaction between endothelial and circulating blood cells. The EG is degraded by various enzymes and reactive oxygen species upon pro-inflammatory stimulus. Ischemia-reperfusion injury, oxidative stress, hypervolemia, and system

OBJECTIVES: Acute kidney injury (AKI) is one of the most frequently occurring complications after off-pump coronary artery bypass graft (OPCAB). Hyperglycaemia is a major, potentially modifiable risk factor of adverse outcome after cardiac surgery known to aggravate organ damage. The aim of this study was to address the association between intraoperative glucose concentration and postoperative AKI in patients who underwent OPCAB. METHODS: The medical records of 880 consecutive patients were retr

AIM: The aim of this study was to investigate the influence of perioperative N-acetylcysteine (NAC) administration, a known antioxidant, on the incidence of acute kidney injury (AKI) after off-pump coronary bypass surgery (OPCAB) in patients with known risk factors of AKI. METHODS: One hundred and seventeen patients with ≥1 of the following risk factors of AKI were randomized into either the control (n = 57) or the NAC (n = 60) group; (i) preoperative serum creatinine >1.4 mg/dL; (ii) left ventr

inhibitor) or glycoprotein IIb/IIIa inhibitors (tirofiban, eptifibatide) may be contemplated. Such a critical decision should be individually tailored based on consensus among the anesthesiologist, cardiologist, surgeon, and patient to minimize both ischemic and bleeding risks.

Degradation of endothelial glycocalyx (EG) is associated with inflammation and endothelial dysfunction, which may contribute to the development of acute kidney injury (AKI). We investigated the association between a marker of EG degradation and AKI after valvular heart surgery. Serum syndecan-1 concentrations were measured at induction of anesthesia and discontinuation of cardiopulmonary bypass in 250 patients. Severe AKI was defined as Kidney Disease: Improving Global Outcomes Criteria Stage 2

Objectives: We investigated whether routine perioperative intravenous iron replenishment reduces the requirement for packed erythrocytes (pRBC) transfusion. Summary of Background Data: Patients undergoing complex cardiac surgery are at high risk of developing postoperative iron deficiency anemia, thus requiring transfusion, which is associated with adverse outcomes. Methods: Patients were randomized to receive either ferric derisomaltose 20 mg/kg (n = 103) or placebo (n = 101) twice during the p

The interventional cardiology is growing and evolving. Many complex procedures are now performed outside the operating room to manage cardiovascular pathologies which had been traditionally treated with cardiac surgery. Appropriate sedation strategy is crucial for improved patient comfort and successful procedure while ensuring safety. Sedation for cardiovascular intervention is frequently challenging, especially in critically-ill, high-risk patients. This review addresses pre-procedure evaluati
