Propofol and alfentanil infusion.

Alfentanil and propofol for difficult intubation?

Total i.v. anaesthesia with propofol-alfentanil or propofol-fentanyl.

In combination with propofol, alfentanil was compared with fentanyl for total i.v. anaesthesia in 29 women (ASA classes I, II) admitted for elective hysterectomy. Infusion rates of propofol and fentanyl were determined from the literature and from pilot studies, while alfentanil was given according to a computer program. Dosage was: propofol, bolus 1.5 mg kg-1, infusion 9 mg kg-1 h-1 for 10 min...

Sedation-analgesia in elective colonoscopy: propofol-fentanyl versus propofol-alfentanil.

BACKGROUND AND OBJECTIVES Sedation-analgesia is recommended for comfortable colonoscopy procedures, which are invasive and can be painful. This study aimed to compare the combinations of propofol-alfentanil and propofol-fentanyl for sedation-analgesia in elective colonoscopy patients. METHODS This prospective and randomized study was planned in ASA I-II groups and included 80 patients between...

Haemodynamic effects of adding ephedrine to propofol and alfentanil.

To the Editor: Crosby et al. present a case of permanent neurological dysfunction following abdominal aneurysectomy and attribute it to a lumbosacral plexopathy caused by an iliopsoas haematoma. ~ I agree with the authors that there is sufficient reason to believe that the iliopsoas haematomas are at least partially responsible for the deficits seen in the femoral and lateral femoral cutaneous ...

Propofol infusion syndrome.

The clinical features of propofol infusion syndrome (PRIS) are acute refractory bradycardia leading to asystole, in the presence of one or more of the following: metabolic acidosis (base deficit > 10 mmol.l(-1)), rhabdomyolysis, hyperlipidaemia, and enlarged or fatty liver. There is an association between PRIS and propofol infusions at doses higher than 4 mg.kg(-1).h(-1) for greater than 48 h d...
