Low-Dose Fentanyl Blunts Circulatory Responses to Tracheal Intubation

Avaliação dos parâmetros hemodinâmicos entre a laringoscopia rígida e o estilete luminoso em pacientes coronariopatas

“…In a study of 950 patients, Hung et al 14 observed that the lighted stylet had a shorter time of intubation, a result different from ours. However, Ellis et al 15 reported similar results to the present study, which showed no statistical significant difference between groups.…”

Bolus administration of esmolol for controlling the haemodynamic response to tracheal intubation: the canadian multicentre trial

“…The practice of administering an opiate analgesic prior to airway instrumentation is well established, and fentanyl has been shown to moderate independently the haemodynamic response to tracheal intubation. 15,16 However, the dose of fentanyl which is necessary to abolish the pressor response completely may be associated with undesirable side-effects, including delayed respiratory depression and, occasionally, hypotension following administration of thiopentone. The multicentre study showed that the combination of esmolol 100 mg with low-dose narcotic (fentanyl 2-3 ixg.kg -1 equivalent) resulted in effective control of both heart rate and blood pressure in response to tracheal intubation.…”

Alfentanil controls the haemodynamic response during rapidsequence induction of anaesthesia

“…A dose of 5-6 I~g" kg -I of a narcotic such as fentanyl, when given prior to induction with thiopentone, is effective in preventing hypertension and tachycardia secondary to intubation. 3,4 However, fentanyl should be administered approximately five minutes prior to induction, in order to allow sufficient time to reach peak analgesic effect before the stimulus of intubation. 8 Furthermore, this technique may be in appropriate for surgical procedures of short duration, due to relatively prolonged respiratory depression with this dose of fentanyl.…”
