It is hard to know; in part it depends on whether there are additional inconsistent codes you want to regularize, or just these three. If it's these three, you can just do:
replace servicio = "HOSP. OBSTETRICIA" if servicio=="HOSP.OBSTETRICIA" | servicio=="HOSP. OBSTETRICIA" | servicio=="OBSTETRICIA C"
With more than a few, though, that would be annoying to type.
Another possibility, is to replace all cases that have the word "OBSTETRICIA" in them:
replace servicio = "HOSP. OBSTETRICIA" if index(servicio,"OBSTETRICIA")
The index() function tells you the character position that the string "OBSTETRICIA" appears in; for cases where it does not appear, the function returns zero and no change is made.
