Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Each of the three arthroplasty procedures are investigated in a 2-arm randomised trial:

Total hip arthroplasty - either spinal anaesthesia or general anaesthesia.

Total knee arthroplasty - either spinal anaesthesia or general anaesthesia.

Unicompartmental knee arthroplasty - either spinal anaesthesia or general anaesthesia.
Primary Study Purpose

TREATMENT

Blinding Strategy

SINGLE

Outcome Assessors
Physcians and nurses in the surgical department are not able to be blinded. But outcome assesors (ie. physiotherapists, research personel) are not aware of the treatment allocation.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Spinal Anaesthesia (SA)

Patients undergoing total hip, total knee or unicompartmental knee arthroplasty are anaesthetized using:

Plain or heavy Bupivacaine hydrochloride 10 mg (2 mL)

Group Type EXPERIMENTAL

Spinal anesthesia

Intervention Type DRUG

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

General Anaesthesia (GA)

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)

Group Type EXPERIMENTAL

General anaesthesia

Intervention Type DRUG

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
