From Wikipedia, the free encyclopedia. Diagenesis /ËdaÉªÉËdÊÉnÉsÉªs/ is the change of sediments or existing sedimentary rocks into a different sedimentary rock during and after rock formation (lithification), at temperatures and pressures less than that required for the formation of metamorphic rocks.It does not include changes from weathering.he term diagenesis, literally meaning across generation, is extensively used in geology. However, this term has filtered into the field of anthropology, archaeology and paleontology to describe the changes and alterations that take place on skeletal (biological) material.
The propofol dosage typically was an initial bolus of 20 to 40 mg, followed by 10 to 20 mg boluses to maintain sedation. Sipe reported that propofol achieved faster time to sedation, greater depth of sedation and faster recovery than midazolam/meperidine sedation. Complication rates were similar.
The standard dose of the combination used for chemical sedation of the agitated patient is âten and twoâ meaning 10mg of Haldol and 2mg of Ativan. You can reduce this to âfive and oneâ or increase it depending on the circumstances.he main disadvantage of Ativan as a chemical sedative is that it can cause respiratory depression, especially when combined with other sedating drugs. For example, it should be used cautiously in the obnoxious drunk. Haldol alone is a better choice for him.
