Preoxygenation before extubation

Si-Jia Lee, Kelvin Howyow Quek
Transnasal Humidified Rapid Insufflation Ventilatory Exchange (THRIVE) is a relatively new noninvasive oxygenation technique with a broad range of applications. It is used in the treatment of type one respiratory failure, as a preoxygenation tool, as a rescue and temporising measure in difficult airways, and as step-down oxygen therapy in patients after extubation. Its use has also been described in laryngeal surgeries, but they mainly involved normal-weight subjects or were used as a bridging oxygenation therapy before definitive airway is secured...

Preoxygenation before anesthetic induction and tracheal intubation is a widely accepted maneuver, designed to increase the body oxygen stores and thereby delay the onset of arterial hemoglobin desaturation during apnea. Because difficulties with ventilation and intubation are unpredictable, the need for preoxygenation is desirable in all patients. During emergence from anesthesia, residual effects of anesthetics and inadequate reversal of neuromuscular blockade can lead to hypoventilation, hypoxemia, and loss of airway patency...

BACKGROUND: Perioperative noninvasive ventilation (NIV) has been proposed to reduce postoperative morbidity and improve perioperative outcomes in patients undergoing general anesthesia. Whether it is advantageous to apply NIV just before and after general anesthesia in obese patients has not been yet established. OBJECTIVES: To perform a qualitative review and meta-analysis to assess the effectiveness and tolerability of perioperative NIV in obese patients. METHODS: All studies in English language performed in clinical setting that compared the application of NIV with standard care just before and after induction of general anesthesia in obese adults (body mass index [BMI]≥35 kg/m(2)) were included...

BACKGROUND: Because there is no detailed description of procedures and perioperative management of major pulmonary resections in swine, we reviewed our experience to delineate the most effective practice in performing left pneumonectomy. MATERIALS AND METHODS: Analysis of 11 consecutive left pneumonectomies. Animal data, operative reports, anesthesia records, and perioperative facts were evaluated. Follow-up information until postoperative day 60, methods of care-taking, therapy administration, and all the stabling aspects were systematically assessed...

The well-known difficulties in airway management in obese patients are caused by obesity-related airways and respiratory changes. Anesthesiologists confront a number of troubles, including rapid oxygen desaturation, difficulty with laryngoscopy/intubation and mask ventilation, and increased susceptibility to the respiratory depressant effects of anesthetic drugs. Preoperative assessment of the airways in the obese should include examination of specific predictors of difficult mask ventilation other than those for difficult intubation...

BACKGROUND: Noninvasive ventilation has assumed an important role in the management of respiratory failure in critical care units, but it must be used selectively depending on the patient's diagnosis and clinical characteristics. DATA: We review the strong evidence supporting the use of noninvasive ventilation for acute respiratory failure to prevent intubation in patients with chronic obstructive pulmonary disease exacerbations or acute cardiogenic pulmonary edema, and in immunocompromised patients, as well as to facilitate extubation in patients with chronic obstructive pulmonary disease who require initial intubation...

UNLABELLED: The benzodiazepine antagonist Ro 15-1788 has now been added to the series of antagonists which have been routinely used for a long time. In the present prospective, randomized double-blind study, it is investigated whether Ro 15-1788 is able to antagonize the effect of midazolam applied at a dosage of 0.2 mg/kg for induction of anesthesia. PATIENTS, MATERIAL AND METHODS: Thirty female patients (age between 19 and 44 years) undergoing laparoscopy were included in the study...

To determine the induction and recovery characteristics of the new poly-fluorinated anaesthetic desflurane, 78 fasting and unpremedicated neonates, infants and children up to 12 yr of age were studied. Patients were stratified according to age: full-term neonates less than 28 days of age (n = 12), infants 1-6 mth (n = 12) infants 6-12 mth (n = 15), children 1-3 yr (n = 15), 3-5 yr (n = 12), and 5-12 yr (n = 12). After preoxygenation for two minutes and an awake tracheal intubation, neonates were anaesthetized with stepwise increases in the inspired concentration of desflurane in an air/oxygen mixture...

In a female patient aged 71, a tumor of unknown histology almost completely occupied the whole of the supraglottic space. Because of the valve-like behaviour of the tumor, the patient could not be ventilated by mask. Therefore, preoxygenation and preservation of spontaneous breathing were essential. Anaesthesia was induced by titration of etomidate, and no muscle relaxant or opioid was administered. The patient was successfully intubated by means of direct laryngoscopy. In all probability the blind nasal technique or the use of a fiberoptic device would not have been helpful, because the tumor had to be luxated before the endotracheal tube could be placed...
