airway exchange catheter

Miguel Alejandro Patiño, Dam-Thuy Truong, Angela Truong, Juan Pablo Cata
Tracheostomy is one of the most ancient and commonly performed surgical procedures. When tracheostomized patients require a subsequent intervention, it is usually necessary to exchange the tracheostomy tube for a tracheal tube, which can be dangerous. These potential complications may be overlooked or underestimated by the anesthesia providers. An inability to ventilate the patient and replace the tube after removal of a fresh tracheostomy tube can escalate rapidly to a life-threatening crisis. We present a case in which an airway exchange catheter was used to safely replace a tracheostomy tube with a tracheal tube in a patient with a fresh tracheostomy...

We report the case ofa pediatric patient with tetralogy of Fallot (TOF) and cleft palate deformity with difficult intubation in which a laryngeal mask airway (LMA) was used and converted into an endotracheal tube through retrograde intubation. The patient with TOF was scheduled for repair of the congenital bilateral cleft lip and palate. Inhalational induction with 4% sevoflurane was started. Conventional tracheal intubation was impossible because the patient had a difficult airway, and the procedure could cause severe cyanosis and respiratory distress...

BACKGROUND: The Ventrain® emergency ventilation device allows active inspiration and expiration through transtracheal catheters or the lumen of an airway exchange catheter. This single-use handheld device is manually operated and driven by an external pressurized oxygen source. The Ventrain® may be used to ventilate patients with a complete or pending upper airway obstruction reducing the risk of barotrauma due to the possibility of active expiration. However tidal volumes (V T) applied and withdrawn with the Ventrain® can only be controlled by visual inspection of chest movements; V T monitoring is not provided...

BACKGROUND: Accumulation of secretions in the airways of patients with an endotracheal tube and mechanical ventilation will have serious consequences. One of the most common methods of airway clearance is endotracheal suctioning. In order to facilitate discharge of airway secretion resulting in promotion of gas exchange, chest physiotherapy techniques can be used at the time of expiration before suction. MATERIALS AND METHODS: In this clinical trial with a cross-over design, 50 mechanically ventilated patients admitted to intensive care units (ICUs) were randomly divided into two groups of thoracic squeezing...

An individualised care plan is described for a woman diagnosed with pneumonia, intubated, and on invasive mechanical ventilation, who was admitted to the Intensive Care Unit for extracorporeal membrane oxygenation (ECMO). A nursing care plan was designed based on Marjory Gordon functional patterns. The most important nursing diagnoses were prioritised, using a model of clinical reasoning model (Analysis of the current status) and NANDA taxonomy. A description is presented on, death anxiety, impaired gas exchange, decreased cardiac output, dysfunctional gastrointestinal motility, risk for disuse syndrome, infection risk, and bleeding risk...

RATIONALE: Acute respiratory distress syndrome (ARDS) is frequently associated with hemodynamic instability which appears as the main factor associated with mortality. Shock is driven by pulmonary hypertension, deleterious effects of mechanical ventilation (MV) on right ventricular (RV) function, and associated-sepsis. Hemodynamic effects of ventilation are due to changes in pleural pressure (Ppl) and changes in transpulmonary pressure (TP). TP affects RV afterload, whereas changes in Ppl affect venous return...

Guided intubation using a tracheal tube and semi-rigid introducer is associated with technical difficulties, failure and traumatic complications. We describe the development of a new system of guidewire-assisted tracheal intubation that may circumvent these problems. A reinforced silicone tracheal tube was modified with a guide channel built inside its wall, and a nitinol non-kinking guidewire was matched to this channel. Both anterograde and retrograde tracheal intubation were evaluated in a test rig, an airway manikin and then in preserved and fresh cadavers...

BACKGROUND: Tracheal tube exchange is a simple concept but not a simple procedure because hypoxemia, esophageal intubation, and loss of airway may occur with life-threatening ramifications. Combining laryngoscopy with an airway exchange catheter (AEC) may lessen the exchange risk. Laryngoscopy is useful for a pre-exchange examination and to open a pathway for endotracheal tube (ETT) passage. Direct laryngoscopy (DL) is hampered by a restricted "line of sight"; thus, airway assessment and exchange may proceed blindly and contribute to difficulty and complications...

Serious complications have been described during oxygenation of patients with airway exchange catheters, due to catheter malpositioning, accidentally applied high airway pressures or high delivered volumes. In this in-vitro study, we analysed gas flow through various airway exchange catheters and described its dependence on driving pressure and entrainment. We applied driving pressures between 0.5 and 2.5 bar and observed maximal flow rates of 3.6 l.s(-1) . Measured gas flow values differed significantly from values calculated according to the Hagen-Poiseuille equation...

In the United States, more than 100,000 tracheostomies are performed annually. Many patients undergoing tracheostomy are critically ill, making them higher risk surgical candidates. Fortunately, the loss of airway during the procedure is rare, but when it occurs, the outcome can be catastrophic. In this report, we describe a technique to minimize the risk of airway loss by using an airway exchange catheter as an airway conduit during endotracheal tube removal. We present 2 clinical cases in which this technique was used successfully and made an important contribution to patient safety...

BACKGROUND: Many airway management guidelines include the use of airway exchange catheters (AECs). There are reports, however, of harm from their use, from both malpositioning and in particular from the administration of oxygen via an AEC leading to barotrauma. METHODS: We used an in vitro pig lung model to investigate the safety of administering oxygen at 4 different flow rates from a high-pressure source via 2 different AECs: a standard catheter and a soft-tipped catheter...

BACKGROUND: Laryngeal tubes (LT) are often used as rescue airway devices. Among prehospital medical personnel, the success rates are high and significantly faster compared to an endotracheal tube (ETT). Therefore, LTs are increasingly used in the prehospital setting. The exchange of an LT for an ETT may often be desirable. Two fiberoptic bronchoscope-facilitated techniques have been described to exchange an LT for an ETT: an intraluminal technique using an Aintree intubating catheter and an extraluminal technique using a nasal route alongside the LT...

Congenital neck masses are associated with high perinatal mortality and morbidity secondary to airway obstruction due to a mass effect of the tumor with subsequent neonatal asphyxia and/or neonatal death. Currently, the only technique designed to establish a secure neonatal airway is the ex utero intrapartum treatment (EXIT) procedure, which involves neonatal tracheal intubation while fetal oxygenation is maintained by the uteroplacental circulation in a partial fetal delivery under maternal general anesthesia...

A 28-year-old male patient with right maxillar, zygomatic arch, orbital wall, and nasal bone fractures had an orthognathic and nasal surgery. Naso-endotracheal intubation is the first choice during surgical correction of dentofacial deformities in an orthognathic surgery; however, its presence can interfere with concomitant surgical procedures on the nose. Traditionally, the naso-endotracheal tube will be removed and replaced with an oro-endotracheal tube. We changed the endotracheal tube from nasal to oral by using an airway exchange catheter...

BACKGROUND: Securing the airway using a tube exchanger catheter is an important and useful technique in anesthesia. Its success is mainly hampered by tube tip impingement of laryngeal structures. Advancing the tracheal tube along its normal curvature via a tube exchanger catheter has a high risk of tube tip impingement mainly of right laryngeal structures. The authors achieved successful clinical experience by rotating the tracheal tube 90° anticlockwise (ventral tube tip position) before railroading the tube via a tube exchanger catheter or a fiber optic bronchoscope through the larynx...

BACKGROUND: We sought to determine whether the design of 3 different double-lumen endobronchial tubes (DLT) (Rusch, Mallinckrodt, Fuji) has an effect on the ease of placement over an airway exchange catheter (AEC) using a video laryngoscope. METHODS: A convenience sample of 17 anesthesia residents and fellows with at least 3 years of anesthesia training was recruited from teaching hospitals in Toronto for a randomized crossover trial. Each participant passed each DLT over an AEC in an airway simulator, visualized and video recorded via a video laryngoscope (GlideScope)...

BACKGROUND: A new technique was proposed to administer surfactant to spontaneous breathing preterm infants by placing a thin catheter through the vocal cords. This technique was not studied with respect to oxygenation, gas exchange, surfactant distribution, and lung mechanics. We tested the technique of less-invasive surfactant administration (LISA) in a spontaneous breathing preterm lamb model. METHODS: Preterm lambs (n = 12) of 133-134 d gestational age were randomized to the following three groups: (i) continuous positive airway pressure (CPAP) only, (ii) CPAP + LISA, and (iii) intubation and mechanical ventilation with surfactant administration...

Abstract High-frequency oscillatory ventilation (HFOV) may improve gas exchange in patients who are inadequately ventilated by conventional mechanical ventilation (CV); however, the hemodynamic consequences of switching to HFOV remain unclear. We compared the effects of CV and HFOV on pulmonary vascular conductance and left ventricular (LV) preload and performance at different airway and filling pressures. In anesthetized dogs, we measured LV dimensions, aortic and pulmonary artery (PA) flow, and mean airway ( AW) and pericardial pressures...
