PURPOSE: The development of a preoperative anesthesia clinic (PAC) can reduce the number of surgical cases canceled on the day of surgery. However, there are only a few studies on the details of cancellations in the operating room. This study aimed to assess the incidence and reasons for surgical cases canceled from admission to the operating room to the start of surgery. METHODS: This retrospective study involved patients who underwent anesthesia performed by anesthesiologists between January 2008 and March 2019...

BACKGROUND: In morbidly obese patients undergoing laparoscopic bariatric surgery, the combination of obesity-related comorbidities, pneumoperitoneum and extreme posture changes constitutes a high risk of perioperative hemodynamic complications. Thus, an advanced hemodynamic monitoring including continuous cardiac index (CI) assessment is desirable. While invasive catheterization may bear technical difficulties, transesophageal echocardiography is contraindicated due to the surgical procedure...

Background: In the perioperative course, alcohol withdrawal syndrome (AWS) can occur in any setting, especially in aero-digestive and acute trauma surgery. Challenging issues are the overlap of other forms of delirium in perioperative and intensive care settings as well as general anesthesia masking the onset of withdrawal symptoms. In contrast to other etiologies of delirium, the pathophysiology and thus treatment strategy of AWS is different: the key point is the tolerance to GABAergic molecules of alcohol-dependent subjects resulting in central nervous hyperactivity once the effect of alcohol or other GABA-stimulating agents is decreased...

BACKGROUND: In children the preoperative hydration status is an important part of the overall clinical assessment. The assumed preoperative fluid deficit is often routinely replaced during induction without knowing the child's actual fluid status. AIM: We investigated the predictive value of the Pleth Variability Index as a measure of fluid responsiveness in spontaneously breathing anesthetized children. METHODS: Pleth Variability Index, stroke volume and cardiac index, measured by electrovelocimetry, mean blood pressure and heart rate were recorded during anesthesia induction in 50 pediatric patients < 6 years...

BACKGROUND Joubert syndrome is a rare autosomal recessive disorder first described in 1969, with an estimated prevalence of 1 in 100 000. Joubert syndrome is characterized by partial or complete agenesis of the cerebellar vermis - the structure that connects both parts of the cerebellum. This results in the main clinical symptoms, such as muscular hypotonia, ataxia, mental retardation, abnormal eye movements, and a central apnea breathing pattern. Joubert syndrome can combine neurological signs with variable multi-organ involvement, mainly of the retina, kidneys, liver, and musculoskeletal system...

Intraoperative mean blood pressure of <60-70mmHg is associated with a higher prevalence of myocardial injury in non-cardiac surgery, acute kidney injury and mortality. Systolic blood pressure of <100mmHg is also associated with an increase rate of myocardial injury in non-cardiac surgery and mortality. The injury is related to the severity and duration of intraoperative hypotension episode. Avoiding the mean arterial blood pressure to decrease below >30% of baseline, is recommended. It is reasonable to normalize mean blood pressure to baseline values as soon as possible...

BACKGROUND: The pathogenesis of Parkinson's disease (PD) involves degeneration of dopaminergic neurons, which is influenced by innate and adaptive immunity. IL-17 is a characteristic cytokine secreted by Th17 cells, which acts as a powerful stimulator of neutrophil migration and infiltration and promotes the secretion of inflammatory cytokines. General anesthesia and surgical stress induce immune and inflammatory responses that activate the immunosuppressive mechanism in the perioperative period...

Balloon test occlusion (BTO) is a useful examination for evaluating ischemic tolerance to internal carotid artery (ICA) occlusion. The aim of this study was to investigate the relationships between intraoperative motor evoked potential (MEP) monitoring and the results of preoperative BTO. Between 2013 and 2017, 32 patients undergoing surgery under general anesthesia with intraoperative MEP monitoring, in whom preoperative BTO was performed, were identified. A receiver operator characteristic (ROC) analysis was performed to determine the appropriate cutoff value of MEP amplitude for BTO-positive...

Certified Registered Nurse Anesthetists (CRNAs) provide care for patients with undiagnosed obstructive sleep apnea (OSA). This evidence-based practice project demonstrated that the STOP-BANG Questionnaire (SB) identified patients with OSA preoperatively and reduced hypoxemia in the postanesthesia care unit (PACU). Evidence from the literature is described; based on this evidence, a change in clinical anesthesia practice was made. Four literature databases were searched using keywords from the following PICOT (patient, intervention, comparison, outcome, time) question: Do patients (P) who have high SB scores (I) compared with patients who do not have high SB scores (C) have a higher incidence of pulmonary complications (O) postoperatively (T)? Five observational cohort studies were critically appraised...

In this study, we report our first experience of applying the concretion visualization method using augmented reality technology. A clinical case of a new surgical intervention on the parotid salivary gland with the localization of salivary stone in its parenchyma is considered. During additional diagnostics, it was found that the size of the concretion exceeds 5 mm which did not allow us to use the endoscopic technologies. That was the reason for the choice of surgical intervention external access using salivary stone visualization with the help of augmented reality...
