Dose requirements in stereoradiography
Stereoscopic viewing of radiographic images is advantageous in reducing ambiguity due to background anatomic noise. This advantage is usually considered to be balanced by doubling the dose required for acquisition of a stereo image pair. In the case of a quantum-noise limited detector, detection theory suggests a possible decrease of the dose by half. We tested this assumption by a series of co...
متن کاملDose requirements of remifentanil for intubation in nonparalyzed Chinese children.
BACKGROUND The objective of this study was to determine ED50 and ED95 of remifentanil for intubation combined with propofol in nonparalyzed Chinese children. METHODS Forty-seven American Society of Anesthesiologists Class I children aged 4-11 years weighing 14-33.5 kg underwent general anesthesia with 2.5 mg·kg(-1) of intravenous propofol followed by remifentanil in Wenzhou, China. The initia...
متن کاملDrug-gene interactions: inherent variability in drug maintenance dose requirements.
The influence of genetics on pharmacokinetics can introduce variability among individual patients that may cause treatment failure, toxicity, or both. Such variability, specifically in clearance rates, can influence drug maintenance dosing regimens.
متن کاملOxytocin requirements at elective cesarean delivery: a dose-finding study.
OBJECTIVE Oxytocin is frequently used by intravenous bolus and infusion to minimize blood loss and prevent postpartum hemorrhage at cesarean delivery. Current dosing regimens are arbitrary whereas large doses may pose a serious risk to the mother. The purpose of this study was to estimate the minimum effective intravenous bolus dose of oxytocin (ED90) required for adequate uterine contraction a...
متن کاملEffect of smoking on dose requirements for vecuronium.
We have compared the potency of vecuronium given to 12 smokers and 12 non-smokers during propofol-alfentanil-nitrous oxide anaesthesia. After obtaining individual dose-response curves, bolus doses of vecuronium were given to maintain neuromuscular block at 90-98% for 60 min. Adductor pollicis EMG was used to monitor neuromuscular block. Mean ED95 values were 61.38 micrograms kg-1 and 47.49 micr...
