Comparative study between the effects of propofol and althesin on histamine release, IgE, C3 and C4 dogs

The effect of the emulsion formulation of propofol on histamine, IgE, C[3] and C[4] levels in comparison with althesin was studied in 20 dogs, divided into 2 equal groups and anaesthetized with either propofol or althesin for a duration of about 30 minutes. The results showed a significantly increased levels of histamine and IgE and a significant reduction in C[3] and C[4] 15 and 30 minutes after induction of anesthesia with propofol and highly significant change were recorded all over althesin anaesthesia. However, changes recorded with propofol were significantly less than that produced by althesin
