During nasotracheal intubation with conventional endotracheal tubes, Magill-tipped, non-thermosoftened tubes seem to be comparable to Murphy-tipped, thermosoftened tubes with regard to trauma on the nasal mucosa.

We evaluated whether pulse pressure variation can predict fluid responsiveness in spontaneously breathing patients. Fifty-nine elective thoracic surgical patients were studied before induction of general anaesthesia. After volume expansion with hydroxyethyl starch 6 ml.kg(-1) , patients were defined as responders by a ≥ 15% increase in the cardiac index. Haemodynamic variables were measured before and after volume expansion and pulse pressure variations were calculated during tidal breathing and

The distance between endotracheal tube tip and vocal cords is directly related to the risk of exubation. Despite tracheal elongation, neck extension actually displaced the endotracheal tube tip to the vocal cords in older children.

In 16% of patients, the IABP was too close to the LSCA origin when it was placed at the aortic knob, whereas positioning the IABP at 2 cm above the carina provided an adequate position for the IABP tip (1.5-3.5 cm distal to the origin of the LSCA) in 95.3% of patients. The carina may be a more reliable landmark for positioning the IABP than the aortic knob.

We report four cases of difficult airway managed with a laryngeal mask airway (LMA) under propofol anaesthesia; this method was chosen to minimize psychological and physical trauma. Case 1 was a boy with dermatomyositis; Case 2, a girl wearing a base ring of a stereotactic frame; Case 3, a boy with Treacher-Collins syndrome; Case 4, a boy with Goldenhar syndrome. They were anaesthesized with propofol and though spontaneous ventilation became shallower, or apnoea occurred, the stimulus of inserti

Ketamine and lidocaine spray appear to be appropriate for laryngeal mask airway (LMA) insertion in children. Thus, apnea and airway obstruction, the two most serious and frequent complications of propofol, can be avoided during LMA insertion.

This method, which requires no specific instrument and no time-consuming technique, can be taught easily and may be used in a situation where the rapidity of lung isolation or collapse is the key to saving life. We conclude that this blind method can be an alternative to the FOB and/or auscultation for the positioning of DLT in an emergency situation.

The correct position of the double-lumen tube is vital for one-lung ventilation, which has been confirmed with a fiberoptic bronchoscope. We devised a simple maneuver to position the double-lumen tube correctly without a fiberoptic bronchoscope.

The double-lumen tube (DLT) is the mainstay of one-lung ventilation (OLV). We sought to determine whether this new intubation maneuver using an endobronchial cuff pressure could be substituted for verification by fiberoptic bronchoscope (FOB) in most conditions requiring left-sided DLT. Seventy-nine patients requiring videoassisted thoracoscopic surgery for pneumothorax or mediastinal mass, or open thoracotomy for lung or esophageal cancer were enrolled in this study. We used 35F (n = 23), 37F (
