Can't intubate can't ventilate

Matthew A Warner, Hugh M Smith, Martin D Zielinski
Invasive airway access by emergent cricothyrotomy remains an essential treatment modality in "can't intubate/can't ventilate" scenarios. Although numerous commercial devices are available, limited comparative data exist with regard to the ventilation and oxygenation parameters of these devices. We report a case of severely compromised respiratory function while using the Quicktrach II, a commercially available emergency cricothyrotomy device. Because of oxygenation and ventilatory insufficiency, our patient required emergent removal of the device and surgical tracheostomy to improve respiratory function...

BACKGROUND: Transtracheal jet ventilation (TTJV) is recommended in several airway guidelines as a potentially life-saving procedure during the 'Can't Intubate Can't Oxygenate' (CICO) emergency. Some studies have questioned its effectiveness. METHODS: Our goal was to determine the complication rates of TTJV in the CICO emergency compared with the emergency setting where CICO is not described (non-CICO emergency) or elective surgical setting. Several databases of published and unpublished literature were searched systematically for studies describing TTJV in human subjects...

This article has summarised a critical discussion of the human factors that contributed to the death of a patient from a failure to respond appropriately to a 'can't intubate, can't ventilate' scenario. The contributory factors included the clinical team's inability to communicate, prioritise tasks and demonstrate effective leadership and assertive followership. The film Just a routine operation has now been in circulation for several years. When a system is designed and introduced with the intention of making a change to clinical practice, it can quickly become just another component of an organisation's architecture and complacency around its use can develop...

BACKGROUND: An unanticipated difficult airway during induction of anesthesia can be a vexing problem. In the setting of can't intubate, can't ventilate (CICV), rapid recovery of spontaneous ventilation is a reasonable goal. The urgency of restoring ventilation is a function of how quickly a patient's hemoglobin oxygen saturation decreases versus how much time is required for the effects of induction drugs to dissipate, namely the duration of unresponsiveness, ventilatory depression, and neuromuscular blockade...

A can't intubate, can't ventilate scenario can result in morbidity and death. Although a rare occurrence (1:50 000 general anaesthetics), it is crucial that anaesthetists maintain the skills necessary to perform cricothyroidotomy, and are well-equipped with appropriate tools. We undertook a bench study comparing a new device, Surgicric(®) , with two established techniques; the Melker Emergency Cricothyroidotomy, and a surgical technique. Twenty-five anaesthetists performed simulated emergency cricothyroidotomy on a porcine model, with the primary outcome measure being insertion time...

We report a case of "can ventilate but can't intubate" situation which was successfully managed in the Emergency Department and Intensive Care Unit by the use of ProSeal laryngeal mask airway and Frova Intubating Introducer as bridging rescue devices. Use of appropriate technique while strictly following the difficult airway algorithm is the mainstay of airway management in unanticipated difficult airway situations. Although the multiple airway devices were used but each step took not more than 2 min and "don't struggle, skip to the next step principle" was followed...

Managing the airway does not mean intubation, it means managing the airway. Allowing a patient to breathe on their own with appropriate positioning, bag-valve ventilation and blind insertion devices are all airway management options. The surgical cricothyrotomy is a rare and life-saving procedure when managing patients who are in a "can't intubate, can't ventilate" situation. These patients will die without aggressive and rapid intervention. While not all surgical cricothyrotomies provide a definitive airway, the needle cricothyrotomy is an ineffective means for ventilation and its use is discouraged...

Emergency and difficult tracheal intubations are hazardous undertakings where successive laryngoscopy-hypoxaemia-re-oxygenation cycles can escalate to airway loss and the 'can't intubate, can't ventilate' scenario. Between 2013 and 2014, we extended the apnoea times of 25 patients with difficult airways who were undergoing general anaesthesia for hypopharyngeal or laryngotracheal surgery. This was achieved through continuous delivery of transnasal high-flow humidified oxygen, initially to provide pre-oxygenation, and continuing as post-oxygenation during intravenous induction of anaesthesia and neuromuscular blockade until a definitive airway was secured...

Although neuromuscular block (NMB) allows immobility for airway management and surgical exposure, termination of its effect is limited by and associated with side effects of acetylcholinesterase inhibitors. Sugammadex is a selective relaxant binding agent that has been shown to reverse deep NMB, even when administered 3 minutes following a 1.2 mg/kg dose of rocuronium. This novel drug is a modified gamma cyclodextrin, that through encapsulation process terminates the effects of rocuronium and vecuronium (aminosteroid muscle relaxants), and enables the anesthesiologists rapidly to reverse profound NMB induced by rocuronium or vecuronium, in a "can't ventilate, can't intubate" crisis...

BACKGROUND: Percutaneous tracheal access is required in more than 40% of major airway emergencies, and rates of failure are high among anaesthetists. Supraglottic airway management is more likely to fail in patients with obesity or neck pathology. Commercially available manikins may aid training. In this study, we modified a standard 'front of neck' manikin and evaluated anaesthetists' performance of percutaneous tracheal access. METHODS: Two cricothyroidotomy training manikins were modified using sections of belly pork to simulate a morbidly obese patient and an obese patient with neck burns...

BACKGROUND: Temporizing oxygenation by percutaneous transtracheal ventilation (PTV) is a recommended emergency technique in 'can't intubate, can't oxygenate' (CICO) situations. Barotrauma risk increases if expiration is obstructed. The Ventrain(®) is a new PTV device that assists expiration. Our aim was to compare key physiological outcomes after PTV with the Ventrain and the Manujet(®) in a large animal obstructed airway model. METHODS: Five anaesthetized sheep had post-apnoea PTV performed for 15 min using the Ventrain or Manujet with the proximal airway completely or critically obstructed, yielding four ventilation protocols per sheep...

The two current cases reported present the situation of "can't intubate can't ventilate" patients with life-saving cricothyrotomy before surgical tracheotomy. These situations emphasize the necessity for clinicians to master difficult intubation and oxygenation algorithms and all available alternative techniques.

The decision to attempt a percutaneous airway in a recognised 'Can't Intubate, Can't Oxygenate' (CICO) situation may occur too late to avoid a poor outcome. Our study was designed to investigate the effect of high-fidelity simulation on the confidence and decision-making ability of anaesthesia trainees in managing CICO scenarios in subsequent simulation. Nine anaesthesia trainees from Logan Hospital participated. Pre-study questionnaires surveying confidence levels in various anaesthetic crises were completed...

A 68-year-old man was diagnosed with severe pharyngeal edema after neck lymph node dissection for cancer of the external ear canal. He was scheduled for an emergency tracheotomy, but preoperative fiberoptic laryngoscopy revealed airway and glottic obstruction due to severe pharyngeal edema. As difficult mask ventilation and tracheal intubation were anticipated, intubation under spontaneous ventilation was performed to avoid a "can't ventilate, can't intubate" situation. The first attempt to intubate the patient using the Pentax-AWS Airwayscope with a thin Intlock resulted in failure due to hindered visualization of the glottis...

BACKGROUND: The effectiveness of simulation is rarely evaluated. The aim of this study was to assess the impact of a short training course on the ability of anesthesiology residents to comply with current difficult airway management guidelines. METHODS: Twenty-seven third-year anesthesiology residents were assessed on a simulator in a "can't intubate, can't ventilate" scenario before the training (the pretest) and then randomly 3, 6, or 12 months after training (the posttest)...

A 53-year-old man with hypopharyngeal stenosis following curative chemoradiotherapy for a tongue base tumour presented three years later for an attempt at pharyngeal dilatation. The first attempt 6 months previously was abandoned when awake fibreoptic intubation failed due to partial airway obstruction and desaturation when the fibrescope was advanced. As mask ventilation was anticipated to be possible, a further attempt at intubation after induction of anaesthesia was judged appropriate. The backup plan was jet ventilation via a cricothyroid cannula sited pre-induction...

A 46-year-old man was diagnosed with descending colon cancer and was planned to undergo left hemicolectomy under general anesthesia. His body mass index was 42.6 and due to his small mouth and jaw, we anticipated difficult mask ventilation and tracheal intubation. To avoid 'can't ventilate, can't intubate', we first inserted a size 3.5 air-Q laryngeal airway under moderate sedation, maintaining spontaneous ventilation. After confirming sufficient assisted ventilation, we used a bronchofiberscope to visualize placement of a gum elastic bougie in the trachea via the air-Q...

This paper provides a detailed overview and discussion of anaesthesia in patients with mucopolysaccharidosis (MPS), the evaluation of risk factors in these patients and their anaesthetic management, including emergency airway issues. MPS represents a group of rare lysosomal storage disorders associated with an array of clinical manifestations. The high prevalence of airway obstruction and restrictive pulmonary disease in combination with cardiovascular manifestations poses a high anaesthetic risk to these patients...
