Determination of the 95% effective dose of remimazolam tosylate in anesthesia induction inhibits endotracheal intubation response in senile patients

Frontiers in Pharmacology, 2023
Background and Purpose: The prevalence of elderly patients prompts anesthesiologists to determine the optimal dose of medication due to the altered pharmacokinetics and pharmacodynamics of this population.

ED95 of remimazolam in nasal administration for attenuating preoperative anxiety in children

Frontiers in Medicine, 2023
BackgroundPreoperative anxiety often prevails in children at higher levels than adults, which is a common impediment for surgeons and anesthesiologists. It is of great necessity to explore an appropriate medication to improve this situation. Remimazolam,

Randomizing a clinical trial in neuro-degenerative disease

Contemporary Clinical Trials Communications, 2023
The paper studies randomization rules for a sequential two-treatment, two-site clinical trial in Parkinson’s disease. An important feature is that we have values of responses and five potential prognostic factors from a sample of 144 patients similar to ...

Nuovi indicatori di sbilanciamento e prevedibilità nei disegni sequenziali randomizzati: confronti fra 'biased coin designs' diversi

Statistica, 2007
Efron's (1971) Biased Coin Design is a well-known randomization technique of sequential clinical trials for comparing two treatments in the absence of prognostic factors that helps neutralize selection bias while keeping the experiment fairly balanced ...

The estimation of minimum effective volume of 0.5% ropivacaine in ultrasound-guided interscalene brachial plexus nerve block: A clinical trial

Journal of Anaesthesiology Clinical Pharmacology, 2019
Background and Aims: Interscalene brachial plexus block (ISB) is the most commonly used mode of anesthesia for upper limb surgeries. Higher volume of local anesthetic used in ISB is associated with increased incidence of side effects, particularly ...

Robust quantum state engineering through coherent localization in biased-coin quantum walks

EPJ Quantum Technology, 2018
We address the performance of a coin-biased quantum walk as a generator for non-classical position states of the walker. We exploit a phenomenon of coherent localization in the position space - resulting from the choice of small values of the coin ...

The minimum effective concentration (MEC90) of ropivacaine for ultrasound-guided caudal block in anorectal surgery. A dose finding study.

PLoS ONE, 2021
BackgroundCaudal epidural block (CEB) provides reliable anesthesia for adults undergoing anorectal surgery. Despite the widely utilization, the minimum effective concentration for 90% patients (MEC90) of ropivacaine for CEB remains unknown.ObjectiveTo ...

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
