We studied 60 children, aged 12 months to 8 yr, undergoing plastic surgery under general anaesthesia supplemented by regional anaesthesia. Patients were allocated randomly to have the laryngeal mask airway removed either on awakening or while anaesthetized. Subsequent observation of respiratory factors and oxygen saturation showed a significant difference between the groups for coughing (P < 0....

OBJECTIVE The objective of this study was to evaluate the rapid training of medical students and their ability to provide effective manual ventilation using the bag-valve-mask technique. METHODS A rapid training session highlighting essential aspects of the correct bag-valve-mask technique was given to 31 medical students. This was followed by a simulated experience with a certified respirato...

Anesthetic management of a parturient with respiratory failure associated with hemoptysis, dyspnea, and orthopnea is difficult. An anesthesiologist should realize that the patient's major problem is not solved during the surgery. This circumstance is similar to a patient with associated cardiac disease scheduled for non-cardiac surgery. General anesthesia with endotracheal intubation can provid...

BACKGROUND/AIM Noninvasive mechanical ventilation (NIMV) is an approach to prevent complications in acute respiratory failure. In this study we aimed to compare the efficacy of a full face mask and a helmet in chronic obstructive pulmonary disease (COPD). MATERIALS AND METHODS Fifty patients were divided randomly into 2 groups as full face mask (Group F) and helmet (Group H). Demographic data...

The 2009 novel influenza A(H1N1) (hereafter " nH1N1 ") pandemic has sparked renewed interest in, and controversy regarding , the use of respiratory protection to reduce influenza transmission. Use of masks to prevent influenza generally applies to 2 populations: health care workers (HCWs) providing care for patients with proven or suspected influenza to both protect the HCW and prevent nosocomi...

BACKGROUND The Airflow Perturbation Device (APD) is a lightweight, portable device that can be used to measure total respiratory resistance as well as inhalation and exhalation resistances. There is a need to determine limits to the accuracy of APD measurements for different conditions likely to occur: leaks around the mouthpiece, use of an oronasal mask, and the addition of resistance in the r...

BACKGROUND Respiratory rate should be monitored continuously in the post-anaesthesia care unit (PACU) to avoid any delay in the detection of respiratory depression. Capnometry is the standard of care but in extubated patients requires a nasal cannula or a face mask that may be poorly tolerated or can be dislodged, leading to errors in data acquisition and false alarms. The value of a new non-in...

We appreciate the interest of Dr Barbarito and colleagues in our recent study 1 comparing the total face mask (TFM) with oronasal mask (ONM) for the treatment of acute respiratory failure in patients receiving noninvasive ventilation (NIV). Our primary (mask comfort and time to apply) and secondary (vital signs and gas exchange parameters over time) end points showed no differences. In the inte...

Because intubation can potentially become a lengthy procedure, the risk of arterial oxygen (O2) desaturation during intubation must be considered. Preoxygenation should be routine, as oxygen reserves are not always sufficient to cover the duration of intubation. Three minutes of spontaneous breathing at FiO2=1 allows denitrogenation with FAO2 close to 95% in patients with normal lung function. ...
