A Quality Study in the use of Post-Anaesthesia Care Unit(PACU) in Hip and Knee Arthroplasty, and the ability to bypass this unit.

The investigators wish to investigate the amount of patients who is required to be secondary admitted to the PACU, after primary discharge from the operating room to the surgical ward, thereby bypassing the PACU.

The investigators wish to investigate the use of our standardized regimen for discharging patients directly to the surgical ward, thereby bypassing the PACU. The anaesthesiology dept. have a local standard operating procedure for doing this, and the patients will be treated according to this.

This means that Patients will be discharged directly to the surgical ward if the following criteria are met:

• American Society of Anaesthesiologist-score (ASA-score) < 3
• Anaesthesia and surgery without any complications, vital signs normal during the whole procedure and not demanding oxygen supplement on the end of the procedure.
• Bloodloss < 500 ml.
• Postoperative evaluation, Early Warning Score, and postoperative score documented in Electronic Patient journal(EPJ).

The patients will upon arrival at the surgery start a registration containing preoperative data(baseline morbidity, sex, height, weight, type of anaesthesia and surgery), perioperative data containing surgery and anaesthesia data, and postoperative discharge-score(local operating procedure).

After discharge to either the surgical ward or the PACU, the patient will be observed closely the first 2 hours while recording every intervention made by the nurse staff.

After the initial 2 hours the recording goes on the next 24 hours recording every event and intervention which lead to a doctor consult, by telephone or physically examining the patient.

Also, the investigators wish to evaluate the use of the discharge Score(Danish Society of Anaesthesia and Intensive care Medicine(DASAIM)-SCORE), which is used as the discharge score after surgery in other hospitals in Denmark, and the investigators therefore record this after surgery, and every 30 minutes after the surgery for the first 2 hours.
