BACKGROUND The aim of the present study was to determine the effect-site concentration of remifentanil needed to prevent haemodynamic instability during tracheal intubation with inhaled desflurane induction. METHODS One hundred American Society of Anesthesiologists I and II female patients were randomized to receive an effect-site concentration of remifentanil of 0, 1, 2, 3, or 4 ng/ml. Induc...

BACKGROUND Although external cephalic version (ECV) can be effective for correcting the fetus in a cephalic presentation, it may be painful for the mother. This study aimed to evaluate the efficacy and safety of remifentanil for pain relief during ECV in China. METHODS In all, 152 Chinese parturients with singleton breech presentation were randomly divided into 2 groups, each with 76 patients...

PURPOSE The incidence of pain induced withdrawal movement following intravenous injection of rocuronium is high. This randomized, double-blind, placebo-controlled study was designed to evaluate the effect of pretreatment of remifentanil on the withdrawal movements due to intravenous injection of rocuronium during anesthetic induction. MATERIALS AND METHODS Ninety adult female patients undergo...

Remifentanil patient-controlled analgesia is well established in many centres and provides satisfactory pain relief for many women in labour. We describe a patient using remifentanil patient-controlled analgesia who suffered a respiratory arrest requiring a brief period of ventilation. In our institution, remifentanil patient-controlled analgesia has been offered to women in labour since 2009. ...

BACKGROUND Rocuronium-induced withdrawal movements can be harmful to patients during the induction period. Remifentanil has been reported to reduce these movements effectively. In this study, we determined the EC(50) of remifentanil for the prevention of rocuronium induced withdrawal movements in male, female, old and child group. METHODS We included patients scheduled for general anesthesia ...

OBJECTIVE Nowadays, there are many pain relief methods for reducing the pain and stress of labor and delivery. In our study, two different remifentanil protocols (bolus and bolus+infusion) administered by patient-controlled analgesia method were compared with intramuscular meperidine for labor analgesia. METHODS Ninety parturients who were scheduled for vaginal delivery were included in this ...

BACKGROUND Propofol is commonly used to anesthetize children undergoing esophagogastroduodenoscopy. Opioids are often used in combination with propofol to provide total intravenous anesthesia. Because both propofol and remifentanil are associated with rapid onset and offset, the combination of these two drugs may be particularly useful for procedures of short duration, including esophagogastrod...

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 ...
