The C-MAC® video monitor attachment is suitable for all otolaryngological scenarios, including post-operative follow up and difficult airway examination. Currently, there are no studies looking at the effectiveness of C-MAC® portable monitor with portable flexible nasoendoscopy. Our study demonstrates that the C-MAC® monitor with portable flexible nasoendoscopy is an excellent tool in terms of medical education, improving patient-doctor communication, efficiency of ward rounds and for medico-legal documentation, with distinct advantages over traditional direct flexible nasoendoscopy...

BACKGROUND: Videolaryngoscopy (VL) is increasingly used, but not yet routine practice, for tracheal intubation. Few departments formally trial equipment before adopting it into practice. We describe the decision-making and implementation processes that our department used when introducing universal VL, with the C-MAC© (Karl Storz, Germany), throughout our anaesthesia and intensive care departments. METHODS: We used a structured process to assess the feasibility of a change to universal VL...

Results using videolaryngoscopy in pre-hospital rapid sequence intubation are mixed. A bougie is not commonly used with videolaryngoscopy. We hypothesised that using videolaryngoscopy and a bougie as core elements of a standardised protocol that includes a drugs and a laryngoscopy algorithm would result in a high first-pass tracheal intubation success rate. We employed videolaryngoscopy (C-MAC) combined with a bougie (Frova intubating introducer) in an anaesthetist-staffed helicopter emergency medical service...

BACKGROUND: Videolaryngoscopy is a valuable technique for endotracheal intubation. When used in the perioperative period, different videolaryngoscopes vary both in terms of technical use and intubation success rates. However, in the prehospital environment, the relative performance of different videolaryngoscopic systems is less well studied. METHODS: We conducted this prospective, randomized, multicenter study at 4 German prehospital emergency medicine centers...

When freshwater resources become scarce there is a trade-off between human resource demands and environmental sustainability. The cost of conserving freshwater ecosystems can potentially be reduced by implementing institutional reforms that endow environmental water managers with a permanent water entitlement and the capacity to store, trade and release water. Australia's Murray Darling Basin Plan (MDBP) includes one of the world's most ambitious programs to recover water for the environment, supported by institutional reforms that allow environmental water managers to operate in water markets...

In cases of multiple facial trauma and other specific cases, the anesthesiologist may be asked to convert an oral endotracheal tube to a nasal endotracheal tube or vice versa. Conventionally, the patient is simply extubated and the endotracheal tube is re-inserted along either the oral or nasal route. However, the task of airway management can become difficult due to surgical trauma or worsening of the airway condition. Fiberoptic bronchoscopy was considered a novel method of airway conversion but this method is not useful when there are secretions and bleeding in the airway, or if the anesthesiologist is inexperienced in using this device...

STUDY OBJECTIVE: Video laryngoscopy has primarily been developed to assist in difficult airways. Using video laryngoscopy in pediatric airway management is an up-and-coming topic. The aim of the presented study was to compare the intubation conditions obtained when using the C-MAC video laryngoscope with Miller blades sizes 0 and 1 for standard direct laryngoscopy and indirect laryngoscopy in children weighing less than 10 kg. DESIGN: This was a prospective study...

AIM: To evaluate and compare the Truview PCD and C-MAC laryngoscopes to the standard Macintosh laryngoscope in paediatric patients. METHODS: One hundred and fifty ASA I-II patients in the age group of 1-6 years (10-20 kg) scheduled for elective surgery were randomised into three equal groups for laryngoscopy and intubation with either Truview PCD (Group T), C-MAC (Group C) or Macintosh (Group M) laryngoscopes under general anaesthesia. Percentage of glottic opening (POGO) score, application of external laryngeal manoeuvre, time to intubation, number of attempts at intubation, failed intubations, episodes of desaturation and trauma caused were recorded and statistically analysed...

Management of airway in patients who have Coffin-Siris syndrome (CSS) is often problematic because most of these patients have difficult airway. NTI via C-MAC VL is an useful alternative to direct laryngoscope for orotracheal intubation in airway and anesthetic management in a case of CSS. Alternative airway devices should be readily available.

The C-MAC videolaryngoscope is the first Macintosh-typed videolaryngoscope. Since the advent of its original version video Macintosh system in 1999, this device has been modified several times. A unique feature of C-MAC device is its ability to provide the 2 options of direct and video laryngoscopy with the same device. The available evidence shows that in patients with normal airways, C-MAC videolaryngoscope compared with direct laryngoscopy can provide comparable or better laryngeal views and exerts less force on maxillary incisors, but does not offer conclusive benefits with regard to intubation time, intubation success, number of intubation attempts, the use of adjuncts, and hemodynamic responses to intubation...

BACKGROUND AND AIMS: In the recent past, many novel devices such as AirTraq(®) and C-MAC(®) video laryngoscope (VL) have been introduced in an attempt to reduce anaesthetic morbidity and mortality associated with difficult intubation. In this study, we aimed to evaluate and compare C-MAC(®) VL with a standard Macintosh blade and the AirTraq(®) optical laryngoscope as a intubating devices with the patient's head in neutral position. METHODS: Sixty American Society of Anesthesiologist Physical Status I-II patients were randomly assigned to be intubated with C-MAC(®) VL (Group CM; n = 30) or AirTraq(®) (Group AT; n = 30) in the neutral position, with or without the application of optimization manoeuvres...

This paper presents a strain-mediated phenomenological corrosion model, based on the discrete finite element modelling method which was developed for use with the ANSYS Implicit finite element code. The corrosion model was calibrated from experimental data and used to simulate the corrosion performance of a WE43 magnesium alloy stent. The model was found to be capable of predicting the experimentally observed plastic strain-mediated mass loss profile. The non-linear plastic strain model, extrapolated from the experimental data, was also found to adequately capture the corrosion-induced reduction in the radial stiffness of the stent over time...
