Filter by:the aim of this study was to evaluate the accuracy of different ultrasonographic parameters and clinical tests to predict difficult airway assessment. Ultrasonographic parameters were: hyo-mental distence, tongue width, skin to epiglottis distence and skin to hyoid bone distence. these parameters were recorded and their predictive acurracy was studied.
The i-gel® mask is a second generation, single use supraglottic airway device which does not have an inflatable cuff. The cuff consists of a thermoplastic elastomer and its mechanism of sealing still remains unclear. Various theories such as temperature-dependent changes in hardness and volume expansion as well as fluid absorption have been discussed.
This is a randomized clinical trial investigating the utility of apneic oxygenation via high flow nasal cannulae during airway management for infants general anaesthesia. Three groups will be compared, a control group at 0 L/min, a 0,2L/Kg/min and a 1L/Kg/min group. The primary outcome will be the time (in seconds) between onset of apnea and one of theses end-points : desaturation (SPO2 <95%) or Airway management completed.
A interventional, non-randomized, controlled study to evaluate the revised iLTS-D2 in anesthetized patients.
Paratracheal pressure may have a role in the prevention of pulmonary aspiration. The effects of paratracheal pressure on glottic view, ease of facemask ventilation, or tracheal intubation are not studied yet. In this study, the subjects are divided into two groups (group I: paratracheal pressure applied during induction of anesthesia, group II: conventional Sellick's maneuver applied during induction of anesthesia). Investigators will assess the glottic view during direct laryngoscopy.
In this self-control experiment, anesthesiologists without experiment of bronchoscopy working in anesthesiology department in Peking Union Medical College Hospital will receive a training and evaluation procedure in simulation and clinical practice about clinical airway management. The objects was (1) to investigate the improvements of manufacturing bronchoscopy in simulation and clinical practice before and after training on simulation, (2) to record the study curve and efforts trainees needed to achieve proficiency and self-confidence on simulation, (3) to record the curve of manufacturing from skilled to unskilled, (4)to evaluate if status manufacturing on simulations could reflect the ones in clinical practice.

Trained anesthesiologist- or emergency physician-divers will perform an airway management in simulated microgravity on a submerged model.
The laryngeal mask is widely used in general anesthesia in children. Selection of an appropriately sized laryngeal mask airway (LMA) is critical to ensure safe and effective use of the device. In children, the appropriate size of the LMA to be used is usually determined by the patient's weight. Up to now, this is the gold standard method, but the weight-related technique is not always possible. The patient's weight is sometimes unknown or medical staff do not remember the relationship between weight and size. Moreover, there are no constant correlations between laryngeal airways and body indices such as height and weight, so that the standard method could cause an inappropriate size of laryngeal mask airway to be chosen. Researchers from Spain introduced a new technique to determine the size of the LMA in children by choosing the LMA that best matched the combined widths of the patient's index, middle and ring fingers, but needs to be formally evaluated in clinical application. In order to compare the application effects of two methods (weight-related and three-fingers), we designed a research plan.
Obesity is omnipresent problem in everyday anesthesiology practice associated with low level of blood oxygen (hypoxemia) during analgo-sedation. Overweight outpatients are often scheduled for colonoscopy usually undergo analgo-sedation. In obese patients, intravenous analgo-sedation often diminish respiratory drive causing hypoxemia. To avoid hypoxemia, low-flow nasal oxygenation (LFNO) of 2-6 L/min is applied via standard nasal catheter to provide maximum 40 % of inspired fraction of oxygen (FiO2). LFNO comprises applying cold and dry oxygen which causes discomfort to nasal mucosa of patient. LFNO is often insufficient to provide satisfying oxygenation. Insufficient oxygenation adds to circulatory instability - heart rate (HR) and blood pressure (BP) disorder. On the other side, high-flow nasal oxygenation (HFNO) brings 20 to 70 L/min of heated and humidified of O2/air mixture up to 100% FiO2 via specially designed nasal cannula. Heated and humidified O2/air mixture is much more agreeable to patient. HFNO brings noninvasive support to patients' spontaneous breathing by producing continuous positive pressure of 3-7 cmH2O in upper airways consequently enhancing oxygenation. Investigators intend to analyze effect of HFNO vs. LFNO on oxygen saturation during procedural analgo-sedation for colonoscopy in obese adult patients. Investigators expect that obese patients with preserved spontaneous breathing, oxygenized by HFNO vs. LFNO, will be less prone to hypoxemia thus more respiratory and circulatory stable during procedural analgo-sedation for colonoscopy. Obese patients with applied HFNO should longer preserve: normal oxygen saturation, normal level of CO2 and O2, reflecting better respiratory stability. Investigators expect obese participnts to have more stable HR and BP, reflecting improved circulatory stability. There will be less interruption of breathing pattern of obese patients and less necessity for attending anesthesiologist to intervene.
