Conditions
Brief summary
Does reducing noise exposure in patients under general anaesthetic improve post operative pain control and reduce strong opiate pain killer usage after an operation. We will randomise patients to either wear earmuffs during their anaesthetic, or to the control group that has a 'business as usual' anaesthetic for their surgery. We will review how many times patients pressed their pain pump button, and what the total dose received of strong opiate pain killers was. We will also review the observation chart where pain scores are recorded. By looking at these records we can see if there is a difference in pain scores and opiate use between the two groups in the study.
Interventions
Fitting standard earmuffs (AS/NZS 1270:2002 Acoustics – Hearing protectors) Class 5 over the ears of a patient under general anaesthetic. The ear muffs will be fitted after the induction of general anaesthesia, prior to knife to skin or equivalent marker of initiation of the surgical procedure. The ear muffs will stay in place for the duration of the surgical procedure. The ear muffs will be removed after final surgical stitch/staple/dressing, prior to leaving the operating room, or prior to ext
Fitting standard earmuffs (AS/NZS 1270:2002 Acoustics – Hearing protectors) Class 5 over the ears of a patient under general anaesthetic. The ear muffs will be fitted after the induction of general anaesthesia, prior to knife to skin or equivalent marker of initiation of the surgical procedure. The ear muffs will stay in place for the duration of the surgical procedure. The ear muffs will be removed after final surgical stitch/staple/dressing, prior to leaving the operating room, or prior to extubation if an endotrachial tube airway is used. A verbal check with the treating anaesthetist to ensure the ear muffs were not required to be removed at any point will be done.
