Extubation-Making the Unpredictable Safer

Faieja Chowdhury, CSM

This document proposes a new algorithm for extubating patients called "VSS+4S+2S". It notes that while considerable research has focused on intubation, relatively little attention has been given to developing standardized guidelines and protocols for safe extubation. The proposed algorithm aims to improve extubation practices, minimize failures, and provide a practical framework for teaching residents. It consists of evaluating Vital Signs Stability, then Stent, Strength, Spontaneous breathing, and Suctioning the patient while still under anesthesia. Once these criteria are met, anesthesia is discontinued and the return of Swallowing and ability to Secure the airway are assessed before full extubation. The goal is to establish standardized steps to guide ext

Extubation failure

Extubation failure is defined as the need for reintubation within 24-72 hours after removal of an endotracheal or tracheostomy tube. Predictors of extubation failure include respiratory mechanics measures like rapid shallow breathing index and airway occlusion pressure. Other predictors are neurologic impairment, weak cough strength, excessive secretions, positive fluid balance, and acute cardiac dysfunction. Management of extubation failure involves treating the underlying causes, continued ventilation, non-invasive ventilation, diuretics, and prophylactic steroids to prevent laryngeal edema. Extubation success relies on careful assessment of neuro-muscular, respiratory, airway, and cardiovascular status to identify patients at risk and intervene early.

This document discusses various types of interfaces used to connect ventilator circuits to patients, including nasal masks, face masks, and full face masks. It describes components like headgear, forehead supports, and elbow joints. Both single circuit and dual circuit ventilator configurations are covered. Key considerations for using non-invasive ventilation in practice include monitoring patients, managing interfaces and circuits, and addressing complications.

Fluid and electrolyte management

Dhritiman Chakrabarti

Fluid and electrolyte management is important for perioperative care. Key points include: 1. Body water is divided into intracellular fluid and extracellular fluid. Common IV fluids contain different electrolyte concentrations and osmolarities. 2. Crystalloids expand plasma volume but leave the intravascular space quickly, while colloids remain intravascular longer but do not correct electrolyte deficiencies. 3. Perioperative fluid management aims to replace pre-existing deficits, normal maintenance needs, and abnormal surgical losses like blood loss, third spacing, and insensible losses. Close monitoring of fluid status is important.

Ventilator Alarm Checklist

Kane Guthrie

This document provides checklists for responding to common ventilator alarms and troubleshooting a crashing ventilated patient. For high airway pressures, possible causes include a tube in the right main bronchus, bronchospasm, mucous plugs, and pneumothorax. For low minute volumes, possible causes are an endotracheal tube cuff deflation allowing an air leak or chest wounds allowing air to escape. The checklist for a crashing ventilated patient follows the acronym D.O.P.E.S. to identify potential problems, then D.O.T.T.S. to address them, such as checking tube position or ventilator settings.

Bronchospasm during induction

Dhritiman Chakrabarti

This case report describes a 25-year-old morbidly obese woman with diabetes who experienced bronchospasm during induction for cochlear implant surgery. Initial signs included absent breath sounds, low end-tidal carbon dioxide, and bronchospasm. Treatment included epinephrine, fluids, bronchodilators, and steroids. Further workup ruled out allergic reaction but found previously undiagnosed asthma. Obesity can precipitate rapid desaturation in asthma patients. Uncontrolled asthma is a risk factor for perioperative bronchospasm.

The study found that: 1) 47 of 51 patients (92%) who were reintubated with an AEC in place were successfully reintubated on the first attempt, with 41 of 47 on the first pass (87% first pass success rate). 2) Complications were low, with only 7 patients experiencing mild hypoxemia during reintubation. 3) Maintaining airway access with an AEC improved reintubation success rates and decreased complications compared to patients who did not have an AEC in place.

Difficult extubation a new management

This letter describes a new technique for managing difficult extubation when the tracheal tube cuff fails to deflate. A patient required laryngoscopy after extubation was initially unsuccessful due to an inflated cuff. The resident made a small V-shaped cut in the tracheal tube wall just beyond the inflating lumen attachment. This allowed air to escape and the tracheal tube was then easily removed. The authors believe this is an easy, quick, and safer method compared to alternatives described in literature. However, one should confirm difficulty is solely due to cuff failure before using this technique.

Pneu x system

This study evaluated the incidence of ventilator-associated pneumonia (VAP) using the PneuX endotracheal tube system with or without elective endotracheal tube exchange. The study found no episodes of VAP while the PneuX system was in use in 53 patients over 48 hours of intubation and mechanical ventilation. On an intention-to-treat basis, the incidence of VAP was 1.8%. The study demonstrated that elective endotracheal tube exchange and intermittent subglottic secretion drainage can be performed reliably and safely using the PneuX system.
