Randomized Controlled Trial Clinical TrialRemifentanil and propofol without muscle relaxants or with different doses of rocuronium for tracheal intubation in outpatient anaesthesia.
Intubation using propofol and remifentanil without muscle relaxant is associated with a greater incidence of poor intubating conditions.

Clinical TrialPain intensity and side effects during titration of morphine to cancer patients using a fixed schedule dose escalation.
Considerable dose variations and frequent initial side effects have been postulated during start of morphine treatment to patients with pain caused by malignant disease. However, to our knowledge, only one previous study has reported effective doses in morphine naive cancer patients and no prospective evaluation has compared symptoms before with symptoms during morphine titration. ⋯ In cancer patients with uncontrolled pain on weak opioids, successful titration of morphine is achieved fast, with a three-fold morphine dose variation and with little increase in side effects.

Randomized Controlled Trial Clinical TrialTopical tenoxicam from pharyngeal pack reduces postoperative sore throat.
One puff of beclomethasone inhaler has been shown to reduce the incidence of sore throat following endotracheal intubation. The aim of this study was to determine the effect of a pharyngeal pack on the incidence of sore throat and whether tenoxicam-impregnated gauze pack significantly influenced the frequency of sore throat. ⋯ The intraoperative use of a tenoxicam-impregnated gauze pack is effective in reducing moderate or severe postoperative sore throat following the use of throat pack.

Clinical TrialChanges in rapidly extracted auditory evoked potentials during tracheal intubation.
One of the problems encountered in assessment of the hypnotic level during anesthesia is the extraction of a consistent and reliable measure online and close to real time. Hemodynamic parameters such as heart rate and blood pressure are not, at least with the traditional single parameter versus time presentation, adequate for ensuring an optimal level of anesthesia, especially when using neuromuscular blocking agents (NMBA). In the literature, it has been demonstrated that auditory evoked potentials (AEP) are able to provide two aspects relevant to determining level of anesthesia: firstly, they have identifiable anatomical significance and, secondly, their characteristics reflect the way the brain perceives a stimulus. ⋯ The ARX-extracted AEP-index increases during tracheal intubation. There is a significant difference between the ARX-extracted AEP and the traditional MTA-extracted AEP, in terms of response time. In order to trace short-lasting changes in the hypnotic level by AEP, the AEP should be extracted by a method with a fast response such as the ARX-model.

Clinical TrialTotal versus tube-related additional work of breathing in ventilator-dependent patients.
In tracheally intubated or tracheostomized spontaneously breathing patients, tube resistance can highly increase the patient's work of breathing. In this study we focused upon the relationship between total (WOBtot) and tube-related additional inspiratory work of breathing (WOBadd) and compared different ventilatory modalities for proper tube compensation. ⋯ In tracheally intubated or tracheostomized spontaneously breathing patients, adequate compensation of tube resistance (i.e. with minimal overcompensation and minimal undercompensation) is best done by the ATC mode.
