During my many years of working in operating theatres, I observed that hydrogen peroxide was adopted by surgeons as a ritual for washing out wounds and deep cavities. An entire bottle of 200 ml hydrogen peroxide was mixed with 200 ml of normal saline. It seems this ritual was passed down from consultant to trainee and it then became a habit. In a recent post on the hub, I mentioned that women in 1920 were given Lysol as a disinfectant to preserve their feminity and maritial bliss! Lysol contains hydrogen peroxide, so women were daily irrigating their vaginas with a harmful solution of fizz, unaware of the hazards. I believe it is still being used to colour hair, remove blood stains, as a mouthwash gargle and also to whiten teeth. Then suddenly a breakthrough! In 2014, in my email inbox, a yellow sticker warning appeared from the Medicines and Healthcare products Regulatory Agency (MHRA) regarding the use of hydrogen peroxide in deep cavities. So why did the MHRA ban the use of hydrogen peroxide in deep cavities? Hydrogen peroxide is contraindicated for use in closed body cavities or on deep or large wounds due to the risk of gas embolism. Hydrogen peroxide breaks down rapidly to water and oxygen on contact with tissues. If this reaction occurs in an enclosed space, the large amount of oxygen produced can cause gas embolism.[1] There has been several case reports that have been published from around the world of life threatening or fatal gas embolism with use of hydrogen peroxide in surgery, of which five were from the UK. Most of the global reports describe cardiorespiratory collapse occurring within seconds to minutes of instillation of hydrogen peroxide as wound irrigation or when used to soak swabs for wound packing. This was sometimes accompanied by features associated with excess gas generation such as surgical emphysema, pneumocephalus, aspiration of gas from central venous lines, or the presence of gas bubbles on transoesophageal echocardiography. Non-fatal events were sometimes associated with permanent neurological damage such as neuro-vegetative state and hypoxic encephalopathy.[1] As the Practice Development Lead for the theatre department where I worked it was my role to pass on and act on the information received from the MHRA, so I discussed it with my very supportive theatre manager and then escalated to the theatre staff. But some consultants still ask for it today; it is always refused. So why do consultants request it when they are aware of the hazards? One theatre never event describes a syringe of hydrogen peroxide given to a consultant and injected into a joint instead of the required local anaesthetic![2] The patient survived but required care in the intensive care unit. As a scrub nurse practitioner this scares me. What about you? Would you now research this yellow sticker alert further, implement best practice and speak up, or would you just keep quiet and go "with the flow?" We all make mistakes, but learning from our errors will always be the ultimate key to improvement in healthcare and best practice and safety for our patients. References 1.

Recently Dr Peter Brennan tweeted a video of a plane landing at Heathrow airport during Storm Dennis. I looked at this with emotion, and with hundreds of in-flight safety information, human factors, communication and interpersonal skills running through my head. I thought of the pilot and his crew, the cabin crew attendants and the passengers, and how scared and worried they would have felt. On a flight, the attendants will take us through the safety procedures before take off. We are all guilty, I am sure, of partly listening because it is routine and we have heard it all before. Then suddenly we are in the midst of a violent storm and we need to utilise that information! We ardently listen to the attendants instructions and pray for the captain to land the plane safely, which he does with great skill! I now want to link this scenario to the care of our patients in the operating theatre. They are also on a journey to a destination of a safe recovery and they depend on the consultants and the team to get them there safely. Despite being routine, we need to do all the safety checks for each patient and follow the WHO Surgical Safety Checklist as it is written: ask all the questions, involve all members of the surgical team, even do the fire risk assessment score if it is implemented in your theatre. The pilot of that flight during Storm Dennis certainly did not think he was on a routine flight. He had a huge responsibility for the lives of his crew and many passengers! We can only operate on one patient at a time. Always remember, even though the operation may be routine for us, it may be the first time for the patient – so let's make it a safe journey for each patient. Do it right all the time!

It happened on a Saturday, 19.30pm, in April 2012. I was the theatre coordinator. We had a 'never event' of a retained swab in a breast wound. The following week, I changed practice following audits for four weeks in eight theatres. We never looked back. Attached is the poster presented in November 2016 at the Patient First Excel conference. Until recently no one ever asked me how I felt. I knew what to do. But I felt for the surgeon. As theatre scrub practitioners we complete counts and inform the surgeon. He acknowledges the count. If later on a swab is retained, it's the surgeon who has to inform the patient and remove it. By using a system especially designed for counting swabs (see video below), we can stop never events of retained swabs and maintain safety for the patient, the consultants, perioperative staff and also the hospital. We have the technology – let's use it! Kathy showcasing the Swabsafe Management poster at the Patient First Event, Excel London.
