A computer program in BASIC for estimation of ED50 and LD50

Computers in Biology and Medicine, 1989
A BASIC computer program for calculating ED50 and LD50 values and their confidence limits by probit analysis and weighted linear regression is presented. It also includes the Chi square procedure for testing the mathematical model and allows on-screen high resolution graphic display.

ED50 and Recovery Times After Propofol in Rats with Graded Cirrhosis

Anesthesia & Analgesia, 2012
Patients with end-stage liver disease have increased sensitivity to general anesthetics. In this study, we sought to quantify sensitivity to propofol as a function of the degree of liver disease, in a rat model of cirrhosis.Liver disease was induced by carbon tetrachloride (CCl(4)) injections for 6, 9, or 12 weeks in 3 study groups.

ED50 of desflurane for laryngeal mask airway removal in anaesthetised adults

Anaesthesia, 2011
Summary Previous estimates for the end‐tidal concentration of desflurane that allows removal of the laryngeal mask airway in 50% of anaesthetised adults (ED50) have ranged from 2.1% to 5.3%. To assess which value is correct, we studied 32 female patients (aged 30–50 years) undergoing intracavity caesium implants ...

ED50 study of femtosecond terawatt laser pulses on porcine skin

Lasers in Surgery and Medicine, 2005
Terawatt (TW) lasers have become commonplace since the development of the chirped-pulse amplification method using Ti:sapphire and Nd:glass laser rods. We have measured the minimum visible lesion (MVL) thresholds for porcine1The animals involved in this study were procured, maintained, and used in accordance with the Federal Animal Welfare Act and the "

Litchfield and Wilcoxon I: Confidence Limits of ED50

1987
The use of the probit conversion for drawing smooth quantal log dose—effect curves was discussed in Procedure 9. Since there are no values of the probit corresponding to 0 and 100% effects the method of Procedure 9 does not handle such complete log dose—effect curves.

[Propofol: ED50 and ED90 induction doses in pediatric anesthesia].

Revista espanola de anestesiologia y reanimacion, 1994
To study ED50 and ED90 induction doses of propofol in children.Seventy-two children from 1 to 110 months of age and premedicated with pentobarbital 4 mg/kg participated in the study. Seven different doses of propofol (1.5, 2, 2.5, 3, 3.5, 4 and 4.5 mg/kg) were injected into the dorsal hand or foot vein in 30 seconds.
