Anesthesia basics

Manuel de la Matta
It is universally accepted that deep sedation involves more risks than light-to-moderate sedation. Deep sedation for endoscopic explorations is normally provided by anesthesiologists in Spain and in most countries of the European Unión. The present debate about deep sedation-anesthesia states goes beyond the topic of cardiovascular and respiratory adverse events, and targets the cognitive consequences and global increased mortality of uncontrolled sedation states, especially in specific fragile populations...

BACKGROUND: Simulation-based training (SBT) has developed into an established method of medical training. Studies focusing on the education of medical students have used simulation as an evaluation tool for defined skills. A small number of studies provide evidence that SBT improves medical students' skills in the clinical setting. Moreover, they were strictly limited to a few areas, such as the diagnosis of heart murmurs or the correct application of cricoid pressure. Other studies could not prove adequate transferability from the skills gained in SBT to the patient site...

Considerable attention has been drawn to poor reproducibility in the biomedical literature. One explanation is inadequate reporting of statistical methods by authors and inadequate assessment of statistical reporting and methods during peer review. In this narrative review, we examine scientific studies of several well-publicized efforts to improve statistical reporting. We also review several retrospective assessments of the impact of these efforts. These studies show that instructions to authors and statistical checklists are not sufficient; no findings suggested that either improves the quality of statistical methods and reporting...

The paper presents basic principles of local anesthesia selection in patients with concomitant somatic diseases. These principles are history taking; analysis of drugs interaction with local anesthetic and sedation agents; determination of the functional status of the patient; patient anxiety correction; dental care with monitoring of hemodynamics parameters. It was found that adhering to this algorithm promotes prevention of urgent conditions in patients in outpatient dentistry.

With a rising incidence of obesity in the United States, anesthesiologists are faced with a larger volume of obese patients coming to the operating room as well as obese patients with ever-larger body mass indices (BMIs). While there are many cardiovascular and endocrine issues that clinicians must take into account when caring for the obese patient, one of the most prominent concerns of the anesthesiologist in the perioperative setting should be the status of the lung. Because the pathophysiology of reduced lung volumes in the obese patient differs from that of the ARDS patient, the best approach to keeping the obese patient's lung open and adequately ventilated during mechanical ventilation is unique...

BACKGROUND: Neurodevelopmental disorders are increasing in prevalence worldwide. Previous work suggests that exposure to the environmental air pollutant and greenhouse gas - nitrous oxide (N2O) - may be an etiological factor in neurodevelopmental disorders through the targeting of several neural correlates. METHODOLOGY: While a number of recent systematic reviews have addressed the role of general anesthesia in the surgical setting and neurodevelopmental outcomes, a narrative mini-review was conducted to first define and characterize the relevant variables (i...

Ongoing investigation from the Pediatric Anesthesia NeuroDevelopment Assessment (PANDA) study hopes to examine the long-term effect on cognitive and language development of a single anesthetic exposure in children undergoing inguinal hernia repair. The fifth PANDA Symposium, held in April 2016, continued the mission of previous symposia to examine evidence from basic science and clinical studies on potential neurotoxic effects of anesthetics on developing brain. At the 2016 Symposium, a panel of specialists from nonsurgical pediatric disciplines including anesthesiology, radiology, neurology, gastroenterology, oncology, cardiology, and critical care reviewed use of anesthesia in their practices, including how concern over possible neurodevelopmental effects of early childhood anesthetic exposure has changed discussion with patients and families regarding risks and benefits of imaging studies and interventional procedures involving sedation or anesthesia...

BACKGROUND: Our existing undergraduate curriculum lacks developing competency for endotracheal intubation. Even though it is a lifesaving procedure, interns are exposed only during their posting in anesthesia or emergency medicine and so, when need arises, they fail to perform endotracheal intubation and it leads to catastrophes. AIMS AND OBJECTIVES: The aim of this study was to develop competency in interns for endotracheal intubation. MATERIALS AND METHODS: A study was conducted on fifty interns of medical college...

Burst suppression, a pattern of the electroencephalogram characterized by quasi-periodic alternation of high-voltage activity (burst) and isoelectric silence (suppression), is typically associated with states of unconsciousness, such as in deep general anesthesia and certain etiologies of coma. Recent computational models for burst suppression have attributed the slow (up to tens of seconds) time-scale of burst termination and re-initiation to cycling in supportive physiological process, such as cerebral metabolism...

BACKGROUND: Transgenic mice are widely used for the study of basic visual function and retinal disease, including in psychophysical tests. Mice have a robust pupillary light reflex that controls the amount of light that enters the eye, and the attenuating effects of the pupil must be considered during such tests. Measurement of the size of pupils at various luminance levels requires that mice remain stable over prolonged periods of time; however, sedation of mice with anesthesia and/or manual restraint can influence the size of their pupils...

OBJECTIVE: We have conducted a basic study on the influences on ultrasonic properties when LIPUS is applied through wound dressing. According to the results of ex vivo experiments conducted to date, LIPUS showed ultrasonic properties such as transmittance, coefficient of transmission, and a non-uniformity ratio through film wound dressing better than other wound dressing, and it was considered that LIPUS's effect for fracture healing was not influenced by film wound dressing. Then, we discussed the influence on the effect of LIPUS through film wound dressing...

Bronchial hyperresponsiveness (BHR) is the most common clinical manifestation identified in asthmatic patients, and intubation is the major factor that stimulates the airway of patients receiving general anesthetic. In the present study, nitric oxide synthase 1 (NOS1) was identified as a target gene of micro (mi)R‑146a using in silico analysis and luciferase assay. Furthermore, the regulatory role of miR‑146a was demonstrated by the observation that the NOS1 expression level in pulmonary artery smooth muscle cells (PASMCs) transfected with miR‑146a mimics was significantly downregulated and the NOS1 expression level in PASMCs transfected with miR‑146a inhibitors was significantly upregulated...

BACKGROUND: Gaining proficiency with various airway management tools is an important goal for anesthesiology training. Indirect video laryngoscopes facilitate tracheal intubation in adults, but it is not clear whether these findings translate to children. This study evaluates the total time to successful intubation when performed by anesthesiology trainees using GlideScope Cobalt® video laryngoscopy (GlideScope), Storz DCI® video laryngoscopy (Storz), or direct laryngoscopy (Direct) in children <2 years old with normal airway anatomy...

The difficult financial situation in German hospitals requires measures for improvement in process quality. Associated increases in revenues in the high income field "operating room (OR) area" are increasingly the responsibility of OR management but it has not been shown that the introduction of an efficiency-oriented management leads to an increase in process quality and revenues in the operating theatre. Therefore the performance in the operating theatre of the University Medical Center Göttingen was analyzed for working days in the core operating time from 7...
