Filter by:Difficult airway management remains the leading cause of anaesthesia-related morbidity and mortality. Obstructive sleep apnea syndrome (OSAS) is a warning sign of difficult airway management. Polysomnography is the gold standard for diagnosis of this syndrome, but the STOP-BANG questionnaire is the preferred screening test. In this study, we wanted to find an answer to the question How successful is the STOP-BANG questionnaire in screening for obstructive sleep apnea syndrome (OSAS) in predicting OSAS, difficult mask and difficult intubation in patients undergoing thoracic surgery?
The purpose of this study is to evaluate the ability of pre-operative ultrasound assessment of neck anatomy in predicting difficult laryngoscopy in obese patients undergoing elective surgery requiring tracheal intubation and comparing it to conventional methods as the Mallampati score in anticipating difficult laryngoscopy.
During a general anaesthetic, patients cannot breathe on their own and have to be artificially ventilated. This is achieved by connecting the patient's windpipe (trachea) to a ventilator via the use of a plastic tube called an endotracheal tube (ETT). To place this ETT into the patient's trachea, an instrument called a laryngoscope is used to lift the tongue and view the entrance to the trachea. This process is called laryngoscopy. The act of placing this ETT into the trachea is called intubation. In anticipation of this procedure, the airway is assessed by the anaesthetist before the patient is put to sleep. This airway examination helps predict if the patient's airway will prove to be difficult to intubate. This assessment is usually carried out face to face with the patient. Since the onset of the COVID 19 pandemic, we have been trying to minimise patient footfall performing anaesthetic assessments before surgery through a video platform. The objective of this study is to compare these video airway evaluations to assessments carried out face to face. We anticipate that the virtual airway assessments will be similar if not the same as the in-person airway assessments.
The aim of this prospective observational study is to evaluate the efficacy of Bonfils fiberoptic stylet to perform tracheal intubation with double lumen tube after failure of standard laryngoscopy in 30 adults patients scheduled for elective thoracic surgery, who require tracheal intubation with double lumen tube for One Lung Ventilation under general anesthesia in a teaching hospital operating theatre at Ospedali Riuniti Ancona (Italy).
Cleverscope is a new medical device that transform a laryngoscope into a videolaryngoscope. previous its commercialization we evaluate its safety and efficacy.
Upper airway ultrasound is a valuable, non-invasive, simple, and portable point of care tool for evaluation of the airway, even in the presence of anatomic distortion caused by pathology or trauma. The ultrasound technology is being increasingly adopted in modern anesthesiology practice. As early as in 1984, some authors have recommended its use to guide venous cannulation, because it shortens procedural times, reduces the number of failed puncture attempts, and minimizes complications. On the other hand, ultrasound-guided techniques are considered the gold standard for peripheral nerve blocks. As ultrasound becomes more widespread, it is important to for anesthesiologists to be aware of the expanding applications of this technology. Current and potential future applications of ultrasound in anesthesiology are wide and include regional anesthesia, neuraxial and chronic pain procedures, vascular access, airway assessment, lung ultrasound, ultrasound neuro-monitoring, gastric ultrasound, focused transthoracic echography, trans-esophageal echocardiography and vascular Doppler flow assessment. The major disadvantage is inter-observer variability, and the fact that it requires is a unique skill that requires continuing training and experience to master the technology. In order to be successful with this technique, it is important to develop a thorough understanding of the sonoanatomy. The normal or abnormal structures need to be imaged and interpreted before any intervention. Airway management is one of the most important tasks for anesthesiologists. Access to the airway should be safe, fast and efficient. Appropriate planning is crucial to avoid morbidity and mortality when difficulty is anticipated. Inability to maintain airway ventilation is a life-threatening situation that may warrant emergent surgical access to prevent devastating consequences. A thorough assessment of the airway is recommended to predict difficulty. Multiple clinical predictors have been used in clinical practice; however, most of them are associated with low predictive values. In consequence, a comprehensive airway examination that incorporates both quantitative and qualitative tests increases the probability of predicting difficult intubation. Regardless of the method of airway evaluation, it is important to acknowledge that clinical airway assessment is not fully accurate and can produce both false-negative and false-positive results. There is a growing academic interest in the ability of ultrasound to determine airway size to estimate appropriate endotracheal tube size. Ultrasound enables us to identify important sonoanatomy of the upper airway including thyroid cartilage, epiglottis, cricoid cartilage, cricothyroid membrane, tracheal cartilages, and esophagus. Transverse and parasagittal views can help diagnose supraglottic, glottic and infraglottic airway conditions and aid the anesthesiologist in airway management. Ultrasonography has brought a paradigm shift in the practice of airway management. With increasing awareness, portability, accessibility and further sophistication in technology, it is likely to find a place in routine airway management.
The purpose of this study is to determine if the Flex-it® Articulating Stylet or the GlideRite® Rigid Stylet is more effective and less traumatic in the context of difficult GlideScope® intubations.
A prospective observational study on predictors available and on variables of difficult intubation adopting Gliscope video laryngoscope routinely. Primary hypothesis of the current study is that the rate of difficult intubation with Glidescope is low and multiple predictors interact favorably in anticipating difficulties.
The aim of this project is to develop a computer algorithm that can accurately predict how easy or difficult it is to intubate a patient based upon digital photographs from three different perspectives. Such an application can provide a consistent, quantitative measure of intubation difficulty by analyzing facial features in captured photographs - features which have previously been shown to correlate with how easy or how hard it would be to perform the intubation procedure. This is in contrast to established subjective protocols that also serve to predict intubation difficulty, albeit with lower accuracy. A digital application has the potential to decrease potential complications related to intubation difficulty and increase patient safety.
