Plain English summary of protocol
Background and study aims
It is common for people undergoing arm surgery to have it done under local or regional anaesthetic and remain fully awake. This type of anaesthesia is commonly known as a 'block'. The block is performed with ultrasound guidance by an experienced anaesthetist. In recent years, virtual reality (VR) headsets have become increasingly affordable and accessible. People are becoming increasingly comfortable with and enjoying using new technology. The aim of this study is to see how the use of virtual reality affects patients' experience under regional or local anaesthesia.
Who can participate?
Patients aged over 18 undergoing upper limb surgery under local or regional anaesthetic
What does the study involve?
Participants are randomly allocated into one of two groups.
One group receives a virtual reality headset and headphones for the duration of the surgical procedure and one group (the control group) do not receive a virtual reality headset and headphones but are still asked to complete some questionnaires on their experience. All participants receive the usual anaesthetic technique . This involves the use of local anaesthetic to numb the area where they are having their operation. It is called a block or regional anaesthetic. Participants' experiences during the procedure are collected using questionnaires.
What are the possible benefits and risks of participating?
What are the possible benefits and risks of participating? Taking part does not change the care participants receive. Participants still have a block performed with ultrasound guidance by an experienced anaesthetist. For some people, motion sickness can be a problem with virtual reality headsets. In the clear majority of cases this is only slight. If this occurs participants can tell the anaesthetist, who will be present and monitoring them throughout, and they can either give them some medicine to help with the sickness or remove the headset. They can ask for the headset to be removed at any time without this affecting the care they receive. Very rarely people find the experience of being awake for the procedure difficult. If this is due to pain or discomfort they can have further local anaesthetic or pain medications through a drip that will placed in a vein before the block is performed. If this doesn’t help they may receive a sedating medication via the drip or a general anaesthetic if this is safe.

| Intervention | Method of Randomisation The randomization process will be undertaken by a person who will not play any other part in the research project. It will be done using the web (pseudo)randomization service: https://www.randomizer.org/. There will be a block randomisation of two groups of 20 to yield even numbers in each group. A series of numbered, sealed packages will be produced with individual numbers written on them, which must be opened in numerical order. Participants will be randomised on the day of surgery by the opening of an opaque envelope determining their group allocation. They will be assigned to one of two groups: a control group or an intervention group. In addition to any intervention, both groups will receive care-as-usual (CAU). Care-As-Usual For these procedures, the patients' anaesthetic treatment options are discussed by the surgeon at the time of being listed for surgery. If the patient chooses to have awake surgery under a regional anaesthesia block then they are listed on specific theatre sessions. Sedation and general anaesthesia are not routinely used during these sessions as it creates organisational problems. Sedation is not offered pre-operatively again, however if sometimes be accommodated. Patients will be invited to take part in the study after they have made their anaesthetic treatment choice and have been listed on a 'regional block list'. If the participant requests sedation during the study, this will be recorded and the participant withdrawn from the remainder of the intervention period. Data collected up to the point of withdrawal will be included for analysis. No formal distraction method will be offered to the control group (e.g. music/TV). However, it is inevitable that ‘Care As Usual’ (and therefore the Control arm) will involve the participants interacting with the theatre staff. This, in itself, is a form of distraction which cannot be withheld. We will note the degree of interaction with theatre staff (e.g. “None”, “During part of the procedure”, “During most of the procedure”) in order to discuss any null findings should they occur. · Full physiological monitoring, according to the Association of Anaesthetists of Great Britain and Ireland (AAGBI) standards, for regional or local procedures as applicable. · Regional or local (field infiltration) anaesthesia. The specific choice will be determined by the surgeon and anaesthetist, based upon the patient and procedural factors, on the day of surgery. · Regional anaesthesia techniques will be performed by one of three nominated senior anaesthetists, experienced in upper limb regional anaesthesia. This will be performed in a dedicated anaesthetic room with AAGBI-compliant monitoring standards. · Regional techniques include ultrasound-guided interscalene, supraclavicular, infraclavicular, axillary and/or median, radial, ulnar nerve blockade. · The exact technique will be at the discretion of the anaesthetist, based on patient and operative factors. · Local (field infiltration) anaesthesia will be administered in theatre by the surgeon performing the procedure. · Local anaesthesia is targeted to the operative site and is performed immediately prior to the start of surgery. Intervention Group Within the intervention group, participants will receive a VR headset and headphones with a pre-programmed ‘scene’, for the duration of the procedure. |
