Summary

In the present study, the purpose was to compare the effects of Nicardipine and Remifentanil on surgical visual field and hemodynamic parameters in microscopic tympanomastoidectomy cases with Controlled Hypotension (CH).

Conditions

  • Other Complications of Surgical and Medical Procedures

Interventions

PROCEDURE

Nicardipine

Following the intubation, the infusion was initiated by using an infusion device (Orchestra Base Primea, Fresenius Kabi) with an i.v. dose of 1.0 µg/kg/min iv in Group N. The targeted MAP was determined as 50-65 mmHg and drug doses were increased until the targeted MAP was achieved In Group N. Nicardipine infusion will be increased by titration in groups with MAP above 65 mm/Hg for more than 5 minutes.

PROCEDURE

Remifentanil

Infusion was administered i.v. using an infusion device (Orchestra Base Primea, Fresenius Kabi). In Group R, the dose will start at 0.05 µg/kg/min following intubation. The target MAP was determined as 50-65 mmHg and drug doses will be increased until the target MAP is reached. HR more than 120 seconds and less than 45 beats/min will be considered as bradycardia and the remifentanil dose will be reduced. If response is unsatisfactory, 0.5 mg Atropine i.v. will be implemented. Nicardipine and Remifentanil infusions in groups will be increased by titration if MAP rises above 65 mm/Hg for more than 5 minutes.
