Randomized Controlled Trial Comparative Study Clinical Trial[Hemodynamic effects of etomidate in cardiac surgery during induction of anesthesia].
For comparison of the induction effects of domestic etomidate on hemodynamics with gamma-OH, each group of thirty patients undergoing either repair of ASD or MVR was randomly selected. Certain hemodynamic parameters involving CI, SI, IC, MAP, HR and SVR (cardiac index, stroke volume index, index of contractility, mean artery pressure, heart rate and systemic vascular resistance) were followed throughout the course of induction. ⋯ MAP and SVR decreased 5 minutes after the administration of drugs (P less than 0.05), while the others showed no significant changes. We conclude that etomidate is superior to gamma-OH in patients for cardiac operations during induction.

Case Reports[Experimental and clinical study of skin stored by vitrification].
To improve the quality of stored skin, vitrification storage method (rapid cooling) was introduced. G group cryoprotective solution (20% DMSO and 6% propylene glycol in kreb's Ringer phosphate solution) was selected from 7 different kinds of solution with low toxicity and high cryoprotective activity. G group solution was proved very effective in cryopreservation of small and large pieces of guinea pig skin. ⋯ The color of skin turned to red within 3-4 days after grafting. There was no blister formation on the surface of grafted skin. If autologous micro-skin were put underneath the stored skin or small pieces of autologous skin were inserted into the small holes of the stored skin, the wounds healed smoothly within six weeks after operation and no further grafting was needed.(ABSTRACT TRUNCATED AT 250 WORDS)
