BACKGROUND: Propofol-remifentanil anesthesia is widely used in adults but few studies are available in infants. We aimed at comparing the hemodynamic effects of propofol-remifentanil vs sevoflurane-fentanyl anesthesia. In addition, we sought to investigate recovery and whether remifentanil induced acute opioid tolerance. METHODS: In total, 39 infants 4-6 months old were ...

BACKGROUND: Target-controlled infusion is a new delivery system for intravenous anesthetic agents with which the anesthetist targets a plasma or effect-site drug concentration to achieve a predetermined effect. With this system, the tedious task of calculating the amount of administered drug required to achieve the target concentration is left in ...

We report the successful use of propofol in the management of a case series (n = 10) of patients with severe, treatment-resistant, postictal agitation (PIA) in the setting of electroconvulsive therapy (ECT). Despite prior inadequate response to intravenous midazolam and other agents, propofol therapy was highly effective with good control ...

Laryngoscopy and endobronchial intubation usually cause transient hypertension and tachycardia. We investigated whether thoracic epidurally injected 3 microg/kg clonidine attenuates cardiovascular responses to intubation compared with 2 microg/kg fentanyl and 1 mg/kg lidocaine. Epidural catheterization was performed at the T6-T7 or T7-T8 intervertebral space, and saline or clonidine in saline ...

GOALS: In a prospective, double-blind study, we examined the effects of routine sedation and pharyngeal anesthesia on cardiorespiratory parameters during gastroscopy. BACKGROUND: Intravenous sedation and topical pharyngeal anesthesia are used to alleviate the discomfort during upper gastrointestinal endoscopy. Cardiorespiratory changes during gastroscopy are common. STUDY: Two hundred fifty two consecutive ...

BACKGROUND: Arousal after sevoflurane anaesthesia has been detectable by monitoring changes in skin conductance (SC) with similar accuracy as monitoring Bispectral Index (BIS). As SC monitoring detects changes in sympathetic tone, the measurements might be confounded by the sympatholytic properties of propofol, a component of total i.v. anaesthesia (TIVA). Therefore ...

BACKGROUND: The effects of anaesthetics on left ventricular (LV) diastolic function in patients with pre-existing diastolic dysfunction are not well known. We hypothesized that propofol but not sevoflurane will worsen the pre-existing LV diastolic dysfunction. METHODS: Of 24 randomized patients, 23 fulfilled the predefined echocardiographic criterion for diastolic dysfunction. They ...

Microemulsions of propofol with nanometer droplet diameter are alternatives to soybean macroemulsions for inducing anesthesia, and may have important advantages. We used a propofol (10 mg/mL) microemulsion (particle diameter 24.5 +/- 0.5 nm) and a commercial macroemulsion to induce anesthesia in dogs (n = 10) using a randomized, crossover design ...

BACKGROUND: In contrast to hypnosis, there is no surrogate parameter for analgesia in anesthetized patients. Opioids are titrated to suppress blood pressure response to noxious stimulation. The authors evaluated a novel model predictive controller for closed-loop administration of alfentanil using mean arterial blood pressure and predicted plasma alfentanil concentration (Cp ...

Our charge was to define anaesthesia as produced by inhaled anaesthetics. A definition may be useful to an understanding of the anaesthetic state, and it may guide studies of the mechanisms by which anaesthesia is produced. All inhaled anaesthetics act on the central nervous system to produce two reversible conditions, ...
