Antiemetics in the ED: a randomized controlled trial comparing 3 common agents.

摘要

I have read the original article entitled "Antiemetics in the ED: a randomized controlled trial comparing 3 common agents" in the American Journal of Emergency Medicine [Mar 2006;24(2): 177-82]. I would like to clarify the following: Data were expressed as means + SD and analyzed by using 1-way analysis of variance with Dunnett procedure for multiple comparisons with a placebo control group (saline only). In Table 2, the means and SDs of intravenous fluid before randomization for total group (83.5 +- 218.3) for droperidol (115.9 +- 265.2), for metoclopramide (56.0 +-172.2), for prochlorperazine (50.0 +- 143.7), and for saline placebo (113.5 + 269.7) were presented. These results showed that the SDs of 5 groups are greater than their mean values. Furthermore, In Table 3, the SD values of sedation and anxiety variables were also larger than the mean values.
