Choice of anesthetics -

anesthesia contributes to patient comfort, providing superior analgesia [23] and maintenance of pulmonary function [24,25]. When thoracic epidural analgesia/anesthesia is used intraoperatively, local anesthetics might induce sympathectomy, including hypotension and bradycardia [26].

Supplemental doses of 0.5 to 1 mcg/kg, incremental increases in infusion rate >0.05 mcg/kg/min, and blood concentrations

This study resulted in a decrease of the MAC of isoflurane by nearly 50% in the group receiving large-dose esmolol with alfentanil. When esmolol was infused without alfentanil, no significant decrease in iso-

The alfentanil requirement varies greatly with this technique (0 7.25 mg) and side ef-fects such as nausea are related to alfentanil dosage. 3 To reduce side effects, we sought to


Alfentanil provided such excellent analgesia and co-operation that it prompted us to defer a thoracic extradural in order to evaluate the continued use of alfentanil for physiotherapy. Alfentanil was diluted to 100 ig ml 1 with water for injection. The pethidine infusion was in-terrupted and alfentanil 200 ug i.v. given over a period of 2 min.

Intravenous techniques in ambulatory anesthesia

Ambulatory anesthesia requires rapid recovery, good quality analgesia, decreased duration of care, and cost-effective techniques. Thus, anesthetic agents in day-case surgery should provide smooth and fast induction of anesthesia, rapid and pleasant recovery, and return to preoperative functional status with optimal postoperative analgesia and

RESEARCH ARTICLE Open Access Comparison between the recovery

Alfentanil, a rapid and short-acting synthetic analog of fentanyl, appears to offer some clinically significant advantages over fentanyl during outpatient anesthesia [9]. Alfentanil was also used as an adjuvant to midazolam for sedation of outpatients undergoing upper gastro-intestinal endoscopy. The use of alfentanil resulted in

A balanced technique, with a combination of propofol and narcotics, has been shown to be highly effective in providing analgesia with a moderate level of sedation for orbital blocks.
