OBJECTIVE We aimed to evaluate the depth of anaesthesia, perioperative haemodynamics, postoperative pain scores, analgesic consumption in patients receiving remifentanil- or alfentanil-based total intravenous anaesthesia for single-level lumbar discectomy. METHODS Seventy patients undergoing discectomy were enrolled in the study. Patients were intravenously administered an initial bolus dose ...
BACKGROUND Remifentanil has been suggested for its short duration of action to replace standard opioids for induction of general anaesthesia in caesarean section. While the stabilizing effect of remifentanil on maternal circulation has been confirmed, its effect on postnatal adaptation remains unclear, as currently published studies are not powered sufficiently to detect any clinical effect of ...
Can remifentanil use in obstetrics be improved by optimal patient-controlled analgesia bolus timing?
BACKGROUND The safety of patient-controlled i.v. analgesia (PCA) with remifentanil for obstetrical analgesia remains a matter of concern. The efficacy of remifentanil bolus application, that is, the coincidence between pain and remifentanil effect-site concentration, may be improved by forecasting contractions, but it is not known whether such a technique would also improve safety. METHODS We...
BACKGROUND Intraoperative infusion of opioids has been associated with increased postoperative pain and analgesic requirements, but the development of tolerance in young children is less clear. This prospective, randomized, double-blinded study was designed to test the hypothesis that the intraoperative administration of remifentanil results in postoperative opioid tolerance in a dose-related m...
Background: Remifentanil is known to produce side-effects of hypotension and bradycardia. In this study, we examine the effect of low-dose ketamine infusion on the heart rate and blood pressure of patients anesthetized with remifentanil.Methods: In a randomized clinical trial, 54 patients aged 20-50 years old, with ASA physical status Ι, were studied in two groups (n=27), Ketamine- Remifentanil...
Background: Blood loss is one of the most critical problems in major surgery. Spinal surgery usually associated with considerable blood loss and allogenic transfusions. Controlled hypotension is one of efficient methods for decreasing operative blood loss. The objective of this study was evaluation of the efficacy of magnesium sulfate in comparison with remifentanil for induction of relative hy...

Introduction Remifentanil target-controlled infusion (TCI), widely used in the operating room owing to its reliability, is poorly assessed in the ICU, while several procedures may induce pain and discomfort. Only one series of 14 patients focused on Remifentanil-TCI use for performing fiberoptic bronchoscopy (FB) in the ICU [1]. We aimed to assess Remifentanil-TCI feasibility, safety and tolera...
Background & Aim: Patients admitted to intensive care units require sedation. The usual drugs for this issue include benzodiazepines, opioids, barbiturates, and hypnotics. This study was conducted to compare the sedative and hemodynamic effects of morphine and remifentanil in traumatized patients requiring intubation and mechanical ventilation in intensive care unit during the years 2003-4....
