Primary	To Know the incidence of postoperative delirium in patients at risk, over 65 years, treated early with prophylactic quetiapine versus placebo.	Proportion of patients diagnosed with delirium (number of cases of delirium / total number of patients) within the first four days in both arms.; 65 years, treated early with prophylactic quetiapine versus placebo.	28 (± 2) days from the start of treatment in each patient.
Secondary	Days without delirium, if it appears.	Number of days from the start of treatment until delirium.	28 ± 2 days from the start (first dose) of treatment with quetiapine.
Secondary	Duration of delirium, if it appears.	Number of days with delirium, if it appears. Perceived quality of life.; Mortality (all causes).	28 ± 2 days from the start (first dose) of treatment with quetiapine.
Secondary	Severity of delirium measured with a validated scale. time of appearance the duration and severity. use of another antipsychotics.	Severity of delirium measured with a the Delirium Rating Scale-Revised-98 (DRS-R-98).	28 ± 2 days from the start (first dose) of treatment with quetiapine.
Secondary	Dose of other antipsychotic (haloperidol).	Total dose (mg) of other antipsychotic to control symptoms of delirium.	28 ± 2 days from the start (first dose) of treatment with quetiapine.
Secondary	Degree of sedation.	Degree of sedation measured with a validated scale Richmond Agitation-Sedation Scale (RASS).	28 ± 2 days from the start (first dose) of treatment with quetiapine.
Secondary	Measurement of corrected QT interval (QTc) prolongation.	Increased (msec) ECG control.	28 ± 2 days from the start (first dose) of treatment with quetiapine.
Secondary	Evaluation of extrapyramidal symptoms.	Presence o absence of extrapyramidal symptoms (tremor, involuntary movements, rigidity).	28 ± 2 days from the start (first dose) of treatment with quetiapine.
Secondary	Days in hospital from surgery.	Number of days from surgery until discharge.	28 ± 2 days from the start (first dose) of treatment with quetiapine.
Secondary	Perceived general well-being.	Evaluation of quality of life using Short Form-36 Health Survey questionnaire (SF36).	28 ± 2 days from the start (first dose) of treatment with quetiapine.
