Effects of fentanyl, droperidol, and innovar on canine cerebral metabolism and blood flow.

Effect of Innovar, fentanyl and droperidol on the cerebrospinal fluid pressure in neurosurgical patients.

FENTANYL ANn DROPFRIDOL, adrainistered either separately or combined in a fixed ratio of 1:50 as "Innovar," have been recommended as adjuncts to local anaesthesia for a wide variety of procedures. 1~ These have included diagnostic procedures, such as cerebral angiography a.~ on neurosurgieal patients, despite the well documented respiratory depression 6,7 associated with "Innovar" and fentanil....

A consideration of prolonged succinylcholine paralysis with Innovar: is the cause droperidol or fentanyl?

Innovar as an adjunct to nitrous oxide, oxygen, curare anaesthesia.

WrTH THE INCREASING concern many anaesthetists are feeling toward the rather routine use of halogenated hydrocarbons, we felt it worthwhile to develop a simple technique to avoid these agents in major surgical procedures. The well recognized use of nitrous oxide (N20) plus oxygen (O2), muscle relaxants and hyperventilation provides adequate operating conditions for certain procedures, i.e. ches...

The effect of Innovar versus droperidol or fentanyl on the duration of action of succinylcholine.

The purpose of this paper is to investigate a phenomenon denied by Collins1 in 1976, but supported in later studies by Wehner 2 in 1979 and Lewis8 in 1982. The phenomenon is potentiation of the muscle relaxing action of succinylcholine by the neuroleptanesthesia agent Innovar,® as measured with a peripheral nerve stimulator. The two types of muscle relaxants used are non-depolarizing and depola...

The effects of droperidol and fentanyl on intracranial pressure and cerebral perfusion pressure in neurosurgical patients.

The effects of droperidol and fentanyl on the intracranial pressure (i.c.p.) and cerebral perfusion pressure (c.p.p.) were studied in eight anaesthetized normocapnic patients with intracranial space-occupying lesions. The infection of droperidol resulted in a small and not significant increase in i.c.p. from 24.0 to 27.2 mm Hg, while c.p.p. decreased from 75.9 mm Hg to 57.8 mm Hg, as a result o...
