Dear Tobias,

Yes. Like in meta-analysis of proportions (e.g., prevalences) or rates 
(e.g., incidences), heterogeneity will probably be larger than for 
comparative meta-analysis, which may make interpretation more difficult.

The function for meta-analysis of means in R package meta is metamean(). 
I would also present a prediction interval (prediction = TRUE).
