Arm Intervention/treatment
Active Comparator: Betapred
16 'Betamethason Sodium Phosphate' tablets dissolved in one ml of water as part of the premedications given to the patient 30 min before the surgery
Drug: Betamethason Sodium Phosphate
Other Name: Betapred

Placebo Comparator: Placebo
One ml of 10% glucose solution as part of the premedications given to the patient 30 min before the surgery
Drug: 10% glucose solution

Primary Outcome Measures :
  1. Postoperative nausea and vomiting [ Time Frame: 0-5 days postop ]
    Nausea/Vomiting postoperatively, numeric Visual Analogue Scale graded from 0 to 10, where 10 is the worst grade of nausea

Secondary Outcome Measures :
  1. Pain [ Time Frame: 0-5 days postop ]
    Postoperative pain, numeric Visual Analogue Scale, graded from 0 to 10, where grade 10 is the worse pain

Other Outcome Measures:
  1. Bleeding [ Time Frame: 0-30 days postop ]
    Postoperative bleeding, visits to Health care. Medical records of the patients are used retrospectively in order to detect any postoperative bleeding that has caused a Contact with the Health care. Such events are divided in a) no of events not demanding new surgery and b) no of events demanding hemostasis by new surgery.
