NCT05706844

Brief Summary

The goal of this randomized clinical trial is to investigate the postoperative recovery following hip and knee arthroplasty procedures depending on the use of either spinal anaesthesia (SA) or general anaesthesia (GA). The main questions are:

  • Are more patients able to be safely mobilized within 6 hours postoperatively when using GA compared to SA?
  • Does postoperative pain, nausea and vomiting, dizzyness, occurence of delirium and urinary retention differ between the anaesthetic methods? Participants, scheduled for total hip, total knee and unicomartmental knee arthroplasty, will be randomized to recieve spinal anaesthesia or general anaesthesia in relation to surgery. At 6 hours postoperatively a physiotherapist will conduct a 5-meter walking test to evaluate whether the participant can be safely mobilized.

Outcome Measures

Primary Outcomes (1)

  • Ability to be mobilsed safely within 6 hours of surgery

    5-meter walking test where a physiotherapist evaluates whether the participant can be safely mobilized within 6 hours of surgery.

    within 6 hours postoperatively.

Secondary Outcomes (4)

  • Fulfilment of discharge criteria

    On the day of surgery: at 4 hours postoperatively and 6 hours postoperatively. From postoperative day 1 and until discharge (on average 1 day): at 10.00 and at 18.00. This will be asses as long as the patient is admitted.

  • Pain score

    On the day of surgery: at 4 hours postoperatively and 6 hours postoperatively. From postoperative day 1 and until discharge (on average 1 day): at 10.00 and at 18.00. This will be asses as long as the patient is admitted.

  • Opioid use in Morphine Milligram Equivilents within the first 6 hours of surgery

    On the day of surgery: Within the first 6 hours after surgery.

  • Nausea Score

    On the day of surgery: at 4 hours postoperatively and 6 hours postoperatively. From postoperative day 1 and until discharge (on average 1 day): at 10.00 and at 18.00. This will be asses as long as the patient is admitted.

Other Outcomes (3)

  • Vital signs - systolic blood pressure

    On the day of surgery: at 4 hours postoperatively and 6 hours postoperatively. From postoperative day 1 and until discharge (on average 1 day): at 10.00 and at 18.00. This will be asses as long as the patient is admitted.

  • Vital signs - diastolic blood pressure

    On the day of surgery: at 4 hours postoperatively and 6 hours postoperatively. From postoperative day 1 and until discharge (on average 1 day): at 10.00 and at 18.00. This will be asses as long as the patient is admitted.

  • Quality of Recovery-15 score

    On the day of surgery: at 4 hours postoperatively. From postoperative day 1 and until discharge (on average 1 day): at 10.00. This will be asses as long as the patient is admitted.

Study Arms (2)

Spinal Anaesthesia (SA)

EXPERIMENTAL

Patients undergoing total hip, total knee or unicompartmental knee arthroplasty are anaesthetized using: Plain or heavy Bupivacaine hydrochloride 10 mg (2 mL)

Drug: Spinal anesthesia

General Anaesthesia (GA)

EXPERIMENTAL

Patients undergoing total hip, total knee or unicompartmental knee arthroplasty are anaesthetized using: Propofol (induction: 1.0-2.0 mg/kg. infusion: 3-5 mg/kg/hour) + Remifentanil (induction: 3-5 mcg/kg, infusion: 0.5 mcg/kg/min)

Drug: General anaesthesia

Interventions

plain or heavy Bupivacaine hydrochloride 10 mg (2 mL) injected in the spinal canal

Also known as: Spinal anaesthesia
Spinal Anaesthesia (SA)

Propofol (induction: 1.0-2.0 mg/kg. infusion: 3-5 mg/kg/hour) + Remifentanil (induction: 3-5 mcg/kg, infusion: 0.5 mcg/kg/min) given intravenously

General Anaesthesia (GA)
