Bypass Post-Anesthesia Care Unit(PACU) in Knee and Hip Arthroplasty - A Quality Cohort Study

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.
