Impact of remifentanil introduction on practice patterns in general anesthesia.
Summary of "Impact of remifentanil introduction on practice patterns in general anesthesia."
The introduction of new medicine can change clinical practice patterns and may affect patient outcomes. In the present study, we investigated whether introduction of remifentanil in Japan affected the practice patterns of anesthesia.
Using the Japanese Diagnosis Procedure Combination database, we extracted records of 423,491 patients who underwent surgery with general anesthesia in 243 hospitals before (2006) and after (2007) the introduction of remifentanil, and identified anesthetic agents used for each patient. A hierarchical mixed-effects logistic regression analysis was performed to analyze the factors that affected selection of remifentanil. Further, we compared postoperative length of stay (LOS), in-hospital mortality, and total costs between 2006 and 2007.
In 2007, remifentanil was used for up to 41.4% of all general anesthesia, accompanied by a reduction in nitrous oxide use and an increase in total intravenous anesthesia. Female gender, increasing age, and preoperative comorbidities including diabetes mellitus, hypertension, liver cirrhosis, and chronic renal failure were positively associated with the use of remifentanil, whereas accompanying cardiac disease and co-application of epidural anesthesia were negatively associated. In 2007, a similar in-hospital death rate, similar or decreased total costs, slightly reduced duration of anesthesia, and substantially reduced postoperative LOS were seen compared to those in 2006.
Our data revealed rapid changes in practice patterns in anesthesia after the introduction of remifentanil in Japan. Remifentanil was used more often in patients with comorbidities and without epidural anesthesia, and its introduction did not affect increase in total medical costs.

Medical and Biotech [MESH] Definitions
Delayed Emergence From Anesthesia
Abnormally slow pace of regaining CONSCIOUSNESS after general anesthesia (ANESTHESIA, GENERAL) usually given during surgical procedures. This condition is characterized by persistent somnolence.
Nurse's Practice Patterns
Patterns of practice in nursing related to provision of services including diagnosis and treatment.
Physician's Practice Patterns
Patterns of practice related to diagnosis and treatment as especially influenced by cost of the service requested and provided.
Dentist's Practice Patterns
Patterns of practice in dentistry related to diagnosis and treatment.
Anesthesia Recovery Period
The period of emergence from general anesthesia, where different elements of consciousness return at different rates.
PURPOSE: Remifentanil has been available in Japan for 3 years. The use of this new opioid is considered a useful adjuvant to general anesthesia. Knowing the exact cost-effectiveness of remifentanil s...
PURPOSE: Although a reduced dose of propofol combined with remifentanil is often used in anesthesia for electroconvulsive therapy (ECT), there have been few studies in which the optimal technique for...
PURPOSE: Remifentanil, a mu-opioid receptor agonist, has important characteristics for neuroanesthesia, but data about its effects on postoperative recovery and mortality are currently lacking. METHOD...
PURPOSE: The objective of this study was to confirm the renal protective effect of remifentanil-based anesthesia in perioperative adult patients with chronic kidney disease (CKD). METHODS: A total of...
PURPOSE: Total intravenous anesthesia (TIVA) with propofol combined with remifentanil or fentanyl has commonly been used to achieve general anesthesia. The purpose of this study...
The purpose of this study is to determine whether remifentanil use in preeclamptic patients may blunt hemodynamic response to intubation during general anesthesia for cesarean section.
The aim of this study is to compare the accuracy of the changes in CVI in response to a standardized noxious stimulus during various targeted pseudo-steady-state concentrations of remifent...

Target concentration infusion(TCI) of remifentanil (2.0ng/ml) suppresses the cough induced by endotracheal tube more effectively than intravenous administration of lidocaine (1.5mg/kg).
