Simplified Use of Mixed Propofol and Alfentanil for Anesthesia in Remote Locations

The use of methylphenidate for emergence from propofol and ketamine anesthesia in dogs

Background: Methylphenidate (MPH) has been used to induce emergence from general anesthesia. OBJECTIVES:  The objective of the present study was to evaluate the effect of MPH on recovery from propofol and ketamine anesthesia in dogs. METHODS: Six healthy male mix-breed dogs weighing 21.9 ± 3.9 kg were used in a randomized crossover design. Thirty minutes after premedication with acepromazine (0...

Esmolol promotes electroencephalographic burst suppression during propofol/alfentanil anesthesia.

UNLABELLED This study examined the effects of an esmolol infusion on the electroencephalogram during propofol/alfentanil IV anesthesia. After informed consent, 20 patients were randomly assigned into four groups on the basis of two target alfentanil concentrations (alfentanil 50 or 150 ng/mL) and of a saline or esmolol infusion. Bispectral index (BIS), burst suppression ratio (SR), and physiolo...

Alfentanil and propofol for difficult intubation?

A Comparative Study of Remifentanil/Propofol versus Alfentanil/Propofol for Wake-up Test in Major Spinal Surgery

Background: Early warning of potential damage to spinal cord during major spinal surgery is highly desirable to prevent post-operative neurological deficits. Wake-up test is a simple, safe and reliable method of recognition of such a complication, and has been extensively used in many spinal surgical units. The present study is evaluating the remifentanil, propofol versus alfentanil, propofol a...

Patient State Index: titration of delivery and recovery from propofol, alfentanil, and nitrous oxide anesthesia.

BACKGROUND The Patient State Index (PSI) uses derived quantitative electroencephalogram features in a multivariate algorithm that varies as a function of hypnotic state. Data are recorded from two anterior, one midline central, and one midline posterior scalp locations. PSI has been demonstrated to have a significant relation to level of hypnosis during intravenous propofol, inhalation, and nit...
