PURPOSE Prevention of cough during emergence after nasal surgery is important for avoiding surgical site bleeding. We investigated the remifentanil effect-site concentration in 50% (EC50) of the elderly patients undergoing nasal surgery for smooth emergence without cough and compared it with that of adult patients. METHODS Twenty-two elderly (aged 65-80 years) and 25 adult patients (aged 20-6...
BACKGROUND This study was designed to investigate whether stepwise tapering of remifentanil at the end of surgery could decrease postoperative pain scores and requirements of rescue analgesics after remifentanil-desflurane anesthesia in patients with thyroidectomy. METHODS Sixty two patients undergoing thyroidectomy under general anesthesia were randomly allocated into two groups. All patient...
BACKGROUND AND OBJECTIVES The combination of ketamine and remifentanil seems to be associated with better analgesia and duration. The aim of this study was to evaluate whether a ketamine-remifentanil combination promotes improved postoperative analgesia. METHODS Prospective, randomized, double blind study of 40 patients undergoing video laparoscopic cholecystectomy. Anesthesia was performed w...
BACKGROUND The surgical pleth index (SPI) is an index based on changes in plethysmographic characteristics that correlate with the balance between the sympathetic and parasympathetic nervous system. It has been proposed as a measure of the balance between nociception and anti-nociception. The goal of this study was to test whether it could be used to titrate remifentanil in day-case anaesthesia...
information was not included in the Methods section of our article. In contrast, however, BIS was relatively low at 3 mg ml of TCI. Although the TCI system does not predict plasma propofol concentration completely, a BIS monitor can be used during general anaesthesia. Remifentanil, however, affects the EEG characteristics during propofol anaesthesia. Therefore, we also wanted to know how remife...
The proliferation, differentiation, and migration of keratinocytes are essential in the early stages of wound healing. Hypoxia-Reoxygenation (H/R) injury to keratinocytes can occur in various stressful environments such as surgery, trauma, and various forms of ulcers. The effects of remifentanil on human keratinocytes under hypoxia-reoxygenation have not been fully studied. Therefore, we invest...
The purpose of the study was to compare the clinical activity of remifentanil or alfentanil under propofol sedation with regard to respiratory rate, sedation and recovery rate when used for outpatient endometrial biopsy. Patients were randomized to receive intravenously either bolus remifentanil 0.4 microgram/kg and propofol 1 mg/kg in the remifentanil group (n = 30), or bolus alfentanil 20 mic...
Neurotransmitter release in the nucleus accumbens core (NACore) during the acquisition of remifentanil or cocaine reinforcement was determined in an operant runway procedure by simultaneous tandem mass spectrometric analysis of dopamine, acetylcholine, and remifentanil or cocaine itself. Run times for remifentanil or cocaine continually decreased over the five consecutive runs of the experiment...
OBJECTIVE To determine women's satisfaction with pain relief using patient controlled analgesia with remifentanil compared with epidural analgesia during labour. DESIGN Multicentre randomised controlled equivalence trial. SETTING 15 hospitals in the Netherlands. PARTICIPANTS Women with an intermediate to high obstetric risk with an intention to deliver vaginally. To exclude a clinically r...
INTRODUCTION This randomised, open-label, multicentre study compared the safety and efficacy of an analgesia-based sedation regime using remifentanil with a conventional hypnotic-based sedation regime in critically ill patients requiring prolonged mechanical ventilation for up to 10 days. METHODS One hundred and five randomised patients received either a remifentanil-based sedation regime (in...
