Filter by:Analgo-sedation is standard procedure in anesthesiology practice and is often given for colonoscopy in the setting of daily hospital. Ideally, patients should be sedated with preserved spontaneous breathing and adequate blood O2 saturation. To maintain adequate oxygenation, low-flow O2 (2-6 L/min) is usually delivered through standard nasal catheter which can provide inspired fraction (FiO2) of 40% (low-flow nasal oxygenation - LFNO). Coldness and dryness of LFNO applied may be uncomfortable to patient. Standardly applied intravenous anesthetics can lead to transient ceasing of breathing and O2 desaturation despite LFNO. Respiratory instability can also potentiate circulatory instability - undesirable changes in heart rate (HR) and blood pressure (BP). Unlike LFNO, high-flow heated and humidified nasal oxygenation (HFNO) is characterized by the oxygen-air mixture flow of 20 to 70 L/min up to 100% FiO2. Warm and humidified O2, delivered via soft, specially designed nasal cannula, is pleasant to patient. HFNO develops continuous positive pressure of 3 to 7 cmH2O in upper airway which enables noninvasive support to patient's spontaneous breathing thus prolonging time of adequate O2 saturation. Aim of this study is to compare effect of HFNO and LFNO on oxygenation maintenance before, during and after standardized procedure of intravenous analgo-sedation in normal weight patients of ASA risk I, II and III. Investigators hypothesize that application of HFNO compared to LFNO, in patients with preserved spontaneous breathing during procedural analgo-sedation, will contribute to maintaining of adequate oxygenation, consequentially adding to greater circulatory and respiratory patients' stability. Investigators expect that patients who receive HFNO will better maintain adequate oxygenation regarding improved spontaneous breathing. Also patients will have shorter intervals of blood oxygen desaturation, less pronounced rise in blood CO2 level and lesser fall of blood O2 level, less change in HR and BP. Investigators will have to exactly estimate partial and global respiratory insufficiency (blood CO2 and O2 levels) associated with LFNO and HFNO, which will be done by blood-gas analysis of 3 arterial blood samples collected before, during and after analgo - sedation via previously, in local anesthesia, placed arterial cannula. Possible complications will be explained in written uniformed consent and by anesthesiologist.
There are several advantages of video laryngoscopy; especially their ability to provide superior glottis visualization, as compared to traditional laryngoscopy.1-3 The purpose of this three arm study was to compare the safety and efficacy of the King Vision® Video Intubation Systems (AMBU-King Systems, Denmark) to the Cobalt GlideScope® (Verathon Medical Inc., USA) in patients with anticipated difficult airways.
Endovascular techniques for the treatment of intracranial aneurysms are growing.
In more than one-in-five cases of out-of-hospital cardiac arrest, airways are blocked by vomit and blood. Sometimes, paramedics cannot clear the airway using methods they have been taught. If the airway cannot be cleared, the patient will die. Usually, these patients will have a breathing tube placed into their windpipe (intubation), as this provides protection from vomit and blood. To do this, the paramedic needs to be able to see the entrance to the windpipe. A new method of clearing the airway called SALAD has been used in patients to help insert a breathing tube, but it is not known whether the method can help paramedics. This study will use a manikin to see if paramedics can insert a breathing tube more often on their first attempt, using SALAD.
The investigators intended to evaluate first success rate and learning curve of trainee anesthetists performing direct and videolaryngoscopy in pediatric airway management.
This study evaluates the efficiency of awake naso-tracheal intubation and patient satisfaction when using a small diameter flexible nasolaryngoscope together with topical anaesthesia and light sedation with a combination of benzodiazepine and fentanyl. The selected patients will have difficult airway access because of obstructing oro- and hypo-pharynx tumours.
This study evaluates the endotracheal tube cuff pressure of a taper-guard cuffed tube during tympanoplasty with ipsilateral rotation of head, compared to the contralateral rotation of head. The investigators will performed the ipsilateral rotation of head against the fixed tube in half of participants or the contralateral rotation of head in the other half.
prospective randomised trial to compare the teaching effect for tracheal intubation following training with McGrath video laryngoscope as direct laryngoscope versus training with McGrath video laryngoscope as video laryngoscope
The study compares the LMA Supreme™ versus the Spritztube® tracheal cannula in anesthetized adult patients. The current randomized study is designed to assess the success placement of blind insertion using LMA Supreme™ , in comparison with the Spritztube® tracheal cannula. In addition, time, number of attempts, easy insertion and the number of complications at insertion and removal will be assessed. The investigators hypothesize that the LMA Supreme™ versus the Spritztube® tracheal cannula will similarly perform during anesthetized adult patients despite differences in their structural design.
The Articulating Oral Airway (AOA) is a novel oral airway which actively displaces the tongue, allowing for a greater cross-sectional area for mask ventilation. The investigators hypothesize that, in patients with predictors for difficult mask ventilation, the AOA will be non-inferior to the Geudel oral airway in terms of expired tidal volumes.
