The addition of a single dose of dexmedetomidine (1 μg/kg) to low-dose remifentanil infusion did not attenuate emergence agitation in intubated patients after orthognathic surgery compared with low-dose remifentanil infusion alone. However, single-dose dexmedetomidine suppressed coughing, haemodynamic changes, and pain during emergence and recovery phases, without respiratory depression. Delayed awakening might be associated with this treatment.

In this retrospective case-control study, we evaluated peri-operative dental injury risk factors following tracheal intubation. Ninety-four of 290,415 patients experienced dental injury following tracheal intubation over a 10-y period. A control group was matched for surgery type and intubating anaesthetist. The incidence of dental injury was 0.03%. Univariate analysis revealed that previous and current difficult intubation, male gender, hepatitis, neurological disease, anticonvulsant use, pre-e

Several studies have reported that the neutrophil to lymphocyte ratio (NLR) and mean platelet volume (MPV) are associated with poor prognosis. This study investigated whether NLR and/or the MPV/platelet ratio could function as predictive markers of mortality in critically ill patients. We retrospectively reviewed 1,154 patients admitted to the intensive care unit (ICU) between January 2017 and December 2017. Patients were divided into 2 groups according to 1-year mortality. We compared the NLR a

Objectives: To investigate if preoperative neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), or mean platelet volume (MPV) could be used to predict 1-year mortality in patients undergoing open abdominal aortic aneurysm (AAA) repair. Methods: We retrospectively reviewed 382 patients who underwent open AAA repair between January 2008 and July 2019. We divided the patients into two groups based on 1-year mortality and compared the preoperative NLR, PLR, and MPV. The patients

Opioid-induced chest wall rigidity is an uncommon complication of opioids. Because of this, it is often difficult to make a differential diagnosis in a mechanically ventilated patient who experiences increased airway pressure and difficulty with ventilation. A 76-year-old female patient was admitted to the intensive care unit (ICU) after surgery for periprosthetic fracture of the femur neck. On completion of the surgery, airway pressure was increased, and oxygen saturation fell below 95% after a

Background: Myocardial injury after non-cardiac surgery (MINS) has been known to be associated with mortality in various surgical patients; however, its prognostic role in abdominal aortic aneurysm (AAA) open repair remains underexplored. This study aimed to investigate the role of MINS as a predictor of mortality in patients who underwent AAA open repair. Methods: This retrospective study investigated 352 patients who underwent open repair for non-ruptured AAA. The predictors of 30-day and 1-ye

In patients undergoing TEVAR, chronic statin use was associated with reduced 30-day MACCEs in non-AAS patients, but not in AAS patients. It might rather be associated with increased risk of AKI in AAS patients.

Carotid intima-media thickness (IMT) is a well-known predictor of adverse outcomes in the ischemic heart disease patients; however, evidence is lacking in patients undergoing off-pump coronary artery bypass surgery (OPCAB). Data from 407 patients who underwent OPCAB between April 2013 and August 2016 were retrospectively reviewed. A composite of cardiovascular morbidity endpoints was defined as the presence of stroke, acute myocardial infarction, new cardiac arrhythmia (newly developed atrial fi

Dexmedetomidine administration for 24 h starting from induction of anesthesia significantly reduced the incidence of postoperative AKI after cardiac surgery for IE (by 29 % vs. control) without hemodynamic side effects. This was accompanied by a significant attenuation of postoperative increase in serum epinephrine levels.

Age and acute hyperglycemia are known risk factors of myocardial ischemia-reperfusion injury. We investigated age-related difference in the effect of acute hyperglycemia on myocardial ischemia-reperfusion injury in Sprague-Dawley rats (young, 3 months; middle-aged, 10-12 months; and old, 22-24 months). The rats received 1.2 g/kg dextrose or normal saline and were subjected to coronary artery occlusion for 45 minutes followed by reperfusion for 240 minutes. Infarct size and ejection fraction were

BACKGROUND: Perioperative hypoalbuminemia has a prognostic effect on mortality and morbidity in various cohorts. Patients undergoing open repair of ruptured abdominal aortic aneurysms (rAAA) are at a high risk of hypoalbuminemia due to bleeding and underlying diseases. Hence, this study aimed to investigate the predictive value of immediate postoperative hypoalbuminemia for the risk for acute kidney injury (AKI) in patients undergoing open rAAA repair. METHODS: We retrospectively reviewed 143 pa
