Filter by:The aim of this observational study is to explore and compare patients' experiences of asleep and awake fibreoptic intubation using a semi qualitative patient questionnaire. In particular, investigators will investigate the occurrence of negative experiences, such as distress and discomfort.
Comparison of cervical spine movement during intubation with the C-MAC Video Stylet to Flexible Bronchoscopy
This study aims to compare using bougie as an assistant for endotracheal intubation through Air-Q and Fastrach intubating laryngeal mask devices when blind intubation fails as attempt to increase its success rate.
One lung ventilation (OLV) is required during thoracic procedure such as lung and esophagus surgery, and carried out by double lumen tube(DLT). Direct insertion of DLT over a fibreoptic bronchoscope (FOB) is considered more difficult and traumatic than that of a single-lumen tube. Recently, One recent simulation study demonstrated that a soft silicone DLT with a flexible, wire-reinforced bronchial tip (Fuji-Phycon tube) may shorten the time to intubation via tube exchange when compared with less compliant, polyvinyochloride(PVC) DLTs such as the Shilly or Rusch DLT. HumanBroncho® (Insung Medical, Seoul, Korea) is a new silicone DLT with a soft, flexible, non-bevelled, wire-reinforced tip. The oval shape, obtuse angle, and short lateral internal diameter of the bronchial lumen and its flexibility may allow for advancement to the trachea over the FOB easier than the Shilly tube. In the present study, The investigators aimed to test the hypothesis that the silicone DLT would be easier than PVC DLT with regard to railroading grade over an FOB. Investigators further aimed to compare the intubation time over the FOB between the silicone DLT and PVC DLT.
Several techniques such as positive airway pressure and head-up tilt during preoxygenation have shown to prolong non-hypoxic apnea period compared to conventional technique. However, uniform recommendations have not yet been made. Therefore, in the present study the investigators attempted to find out the effect of combination of 5 cmH2O CPAP and 25° head up position during preoxygenation.
In the previous study on mannekin, the investigators found stylet-assisted lifting of epiglottis is an useful technique on difficult airway (Cormack-Lehane grade IIIa, IIIb) without increasing subjective difficulty. It has no expenses other than the routine intubation process. Recently, the studies have proved that the bougie-assisted laryngoscopy can improve first pass intubation rate in the emergency department. However, bougie is a disposable device and may increased medical expenditure. The investigators will evaluate the safety of bougie and epiglottic lifting technique, as well as the first pass and overall success rate of intubation comparing to traditional video laryngoscopy and direct laryngoscopy.
Nowadays, the gold standard for difficult airway management is awake intubation with a flexible fiberscope. Alternatively, when the flexible fiberscope is unable to facilitate tracheal intubation, rigid stylets may be used. One newly developed rigid video stylet also features a flexible tip (C-MAC VS, Karl Storz AG, 78532 Tuttlingen, Germany). The distal angular offset of the C-MAC VS, in which the camera and light sources are integrated, can be aligned (up to 60°) to the patient's anatomical structures to facilitate intubation. Although awake intubation is less comfortable for the patient and more time consuming, there are several reasons why this is often performed. The investigators plan a prospective observational with 36 participants using the C-MAC VS on adult patients with indication for awake oral intubation. To ease the placement of the tube (intubation), the investigators will use local anesthesia of the mucosa in the mouth, pharynx and larynx. The main purpose of the study is to prove the feasibility of successful awake intubation with the C-MAC VS in adult patients. If the new device proves reliable in facilitating awake oral, future patients benefit from an additional tool that allows fast and safe intubation in difficult airway situations.
Airway management and tracheal intubation are routinely performed in paediatric anaesthesia and yet are associated with preventable adverse events. The D-blade of videolaryngoscope is preferred in difficult intubation with a more curved blade then the Macintosh videolaryngoscope blade, which may be more useful in difficult intubation. The aim of the study is to compare the D-blade of videolaryngoscope with Macintosh videolaryngoscope blade.
Upper gastrointestinal (GI) bleeding is defined as patients who either presented with hematemesis or presented with melena along with evidence of hemodynamic compromise. These patients have risk of aspiration of blood along with gastric content. The mortality rate can be 15% to 20% in the cases with variceal bleeding. From a practical standpoint, it is widely accepted that the best way to secure an airway during upper GI bleeding is prophylactic endotracheal intubation (PEI). The aim of this study is to determine the incidence of complications among critically ill patients with upper GI bleeding and received urgent endoscopy.
Patients who are obese, as defined by a BMI ≥ 30 kg/m2 may be more difficult to intubate than non-obese patients. Traditional methods of airway assessment such as Mallampati score, mouth opening, and thyromental distance may not be the best predictors of difficult intubation. Patients who are scheduled to have non-stat surgery at Parkland Memorial Hospital will be asked to participate in this study and sign a written consent form. Physiologic measurements including but not limited to thyromental distance, sternomental distance, Mallampati score, mouth opening, interincisor distance, and mandibular protrusion will be measured and recorded. All measurements are non invasive. The remaining aspects of perioperative care, including the general anesthetic technique, will be standardized for all patients and will not differ from the standard of care. There will be no incentive or payment to the patients. This prospective study is intended to enroll 4500 consecutive surgical patients. Lean patients (BMI < 30 kg/m2) who are intubated by the same anesthesia providers during the same time period will be included as the control group and to report the incidence of difficult mask ventilation and difficult intubation in our general surgical population, which has not previously been defined.
