Problems with Stored Procedures on Laravel 5.6?

Question

I’m making a select in a procedure, but I can’t page because the result returns array:

DB::select('EXEC PR_MONITORAMENTO @FUNCAO="S2", @ID_CD_INTERNACAO='.$ID_INTERNACAO.', 
     @ID_CD_CONVENIO='.$ID_CONVENIO.',@NM_PESSOA= '.$NM_PESSOA.'');

And when I do a db::raw it returns an object with the name

DB::raw('EXEC PR_MONITORAMENTO @FUNCAO="S2", @ID_CD_INTERNACAO='.$ID_INTERNACAO.', 
     @ID_CD_CONVENIO='.$ID_CONVENIO.',@NM_PESSOA= '.$NM_PESSOA.'');

---

object(Illuminate\Database\Query\Expression)#290 (1) 
{ 
    ["value":protected]=> string(95) 
    "EXEC PR_MONITORAMENTO @FUNCAO="S2", @ID_CD_INTERNACAO=, 
        @ID_CD_CONVENIO=,@NM_PESSOA= " 
}

I want to do the select in that procedure and page, any hint?
