Optimization of programmed intermittent epidural bolus volume for different concentrations of ropivacaine in labor analgesia: a biased coin up-and-down sequential allocation trial

BMC Pregnancy and Childbirth, 2022
Background and objectives To date, programmed intermittent epidural bolus (PIEB) has been widely used in obstetric analgesia, while no optimal PIEB regimen has been proposed.

95% effective volume of ropivacaine for ultrasound‑guided supra‑inguinal fascia iliaca compartment block

BMC Anesthesiology, 2023
Background Hip arthroplasty is effective in treating hip diseases, such as osteoarthritis and hip fracture, but it often brings severe trauma and pain. In recent years, ultrasound-guided supra-inguinal fascia iliaca compartment block(S-FICB) has become a

Study on MEV90 of 0.5% ropivacaine for US-guided caudal epidural block in anorectal surgery

Frontiers in Medicine, 2023
BackgroundChoosing the appropriate concentration and volume of anesthetics is critical for a successful nerve block. The current study aimed to determine the minimum effective volume (MEV) of 0.5% ropivacaine for US-guided CEB in 90% of patients (MEV90 ...

Determination of the 95% effective dose of remimazolam to achieve loss of consciousness during anesthesia induction in different age groups [PDF]

Korean Journal of Anesthesiology, 2022
Background Remimazolam is a new ultra short-acting benzodiazepine originally developed as an improved version of midazolam. Recent studies have demonstrated non-inferiority of remimazolam to propofol in general anesthesia.

A study to determine minimum effective dose of oxytocin infusion during caesarean delivery in parturients at high risk of uterine atony

Journal of Obstetric Anaesthesia and Critical Care, 2017
Background: Oxytocin, a commonly used drug to prevent uterine atony after caesarean section, should be administered as dilute rapid infusion rather than as a bolus. This study was conducted to calculate ED90 of oxytocin infusion during caesarean delivery

Inference following biased coin designs in clinical trials. [PDF]

, 2013
PhDRandomization schemes for two-treatment clinical trials are studied. Theoretical expressions for the power are derived under both complete randomization and Efron’s biased coin design for normal and binary responses.

Detecting Anomalous Cell Behavior in Electrochemical Battery Testing Using Machine Learning

Advanced Engineering Materials, EarlyView.
Machine‐learning‐based screening enables automated identification of anomalous battery cells from complementary electrochemical tests. A curated battery database supports configuration‐aware comparison of rate‐capability and impedance data. Supervised classification of rate‐test data achieves 90% accuracy, while CNN‐VAE‐based impedance analysis reaches

Selecting a biased-coin design

, 2014
Biased-coin designs are used in clinical trials to allocate treatments with some randomness while maintaining approximately equal allocation. More recent rules are compared with Efron's [Biometrika 58 (1971) 403-417] biased-coin rule and extended to ...
