Abstract
OBJECTIVES: COVID-19 presents a risk of infection and transmission for operating theatre teams. Guidelines to protect patients and staff emerged and changed rapidly based on expert opinion and limited evidence. This paper presents the experiences and innovations developed by international surgical teams during the early stages of the pandemic to attempt to mitigate risk.Entities:

Modifications to practice for intubating patients
| Example | Quotation |
| Changes to mode of anaesthesia | HP40: One of the innovations that has happened as a direct result of COVID is that surgical procedures that, up until now, we would have said were general anaesthetic procedures have been successfully converted to local procedures… We would never have contemplated doing an enucleation—removing the eye—under a local anaesthetic before. Now, we have successfully done that. |
| Changes to where the patient is intubated | HP28: The anaesthetic is being conducted in the theatre whereas normally it would be done in the anaesthetic room in the UK … It just means that they are not moving between lots of different places as well, so they try to minimise the number of points that the patients will stop at. |
| Changes to where patient extubated | HP4: Now we would actually wake the patient up in theatre and have them awake in theatre before they went out, where previously, patients would routinely be taken to the recovery area mostly asleep… In the past, where you might have a patient waking up with an airway in, coughing it out, coughing and spluttering a bit. But actually if they do all that whilst we're in the theatre environment, which is already contaminated, and we're all in protective kit. |
| Reducing aerosolisation during intubation | HP34: If you put a plastic sheet over the head of the patient that reduces much of the aspiration, so the spit, coming out and then the aerosolisation which causes spit will sit on that plastic more than hit you in the face or the neck or anything like that. Those are good things that came out and you can actually see it, the one I saw, you saw all of the spit on the patient, when you extubate, the spit went all over the patient, if you didn’t have that plastic sheet, that would be, because your neck is still exposed and all of that. |
| Pausing to allow aerosols to be dissipated | HP17: There’s a delay between the patient being put to sleep and the operation being started, just to allow the air to be changed in theatres. The rationale behind that being that when someone’s put to sleep and they’ve got a breathing tube put down, the virus might be kind of put into the air, they might be floating around. Operating rooms have got incredibly high air flow, the air is changed—it depends on your particular operating theatre but each individual hospital will know how long it takes to cycle the air out of their theatre, and then they can do a bit of maths to see how long it takes for the air in there to be entirely fresh. It’s normally about 20, 25 minutes. |
Modifications to forming a tracheostomy
| Example | Quotation |
| Being performed only by a small team of experts | HP43: Early on, I was interested in working [on tracheotomies] and a surgeon was interested in it as well. Our personalities work reasonably well together and we started, from the surgical side at least, combining forces and trying to figure out a way to do this safely… We weren't exactly sure which patients were going to make the most sense. We didn't know who exactly would benefit from it, but there was little question there were going to be some people … We go into the room, we wheel in all our stuff. We don't even talk that much anymore. Teamwork is very crucial… I think it has been important, both from an operational standpoint, but also from a mental support and enthusiasm standpoint. I think, if one of us was doing this alone, without the other, I think it would be a lot more difficult. I wouldn't say it’s undoable on your own completely, but it’s just crazy to try to do that. You have to ask for help. |
| Pausing the ventilator | HP41: I think a tracheotomy is more risk… Before we cut open, cut open the trachea, we make the ventilator pause for a second. Then first we pause the ventilator, then we cut, and then we insert the intubation quickly, and we restart the ventilator … If the ventilator is open, then there are a lot of aerosols… Secretion maybe comes out from the lungs, from the bronchia. So if we pause the ventilator, maybe they can decrease the secretions. |
| Location of tracheotomy | HP41: All the tracheotomy is at the bedside. So it’s including a resident, to help at the head side of the patient, and two surgeons. One is at the bedside, to do the surgery. And one or two nurses help to deliver some things to help the surgery. Now, the unit is the ICU unit. There’s one person per room. |

Modifications to AGPs
| Examples | Quotation |
| Wearing full PPE | HP28: We would use keyhole surgery and we use various adaptations for the keyhole …we did everything with PPE at the time we saw the patient, full PPE in theatre (…) We went against guidance and used keyhole surgery because we felt that there was no evidence to suggest that it’s any more risky. |
| Use of smoke-filter evaporators | HP21: We use filters to avoid aerosols, every port is connected to a filter so no aerosol comes through the port… We fix the port to the skin to avoid accidental removal, apply a stitch to the port and fix it to the skin, so the chances of the port being accidentally removed is really decreased. |
| Plastic sheets | HP12: We cover the head and the drill with this plastic sheet that aerosols are not going into the air, and not going everywhere, to protect the environment and to protect the surgeons. |
| Drapes | HP18: We’re using some simple things like some plastic drapes over the top of the really aerosol generating stuff that we’re doing, making some holes in those drapes so that we can still use our normal instruments. |
| Adopting a combination of approaches | HP20: Tracheostomies were done percutaneously … They have done some modification, doing some combination between open and percutaneous tracheostomy…to minimise as much as possible the risk of leaking aerosol in the operative field to the operative team. |

Problems caused by PPE and potential strategies to overcome these issues
| Issue caused by PPE | Quotation | Potential solution | Quotation |
| Time taken to don PPE | HP19: It’s made the operations much longer, by the time you get the kit on. | ‘Grab bags’ | HP4: We've set up a fantastic production line of grab bags. So, everything we need is in one of a series of grab bags.(…)We're going off to intubate someone, so we want that bag and that bag. We're going to put lines in them, so we want that bag. |
| Difficulty determining who is who | HP3: You can’t take name badges in. | Name and roles written on PPE | HP11: People do write their names on their gowns or aprons… The problem is you don't know what their role is. They should actually write, ‘ITU Nurse’. |
| Difficulty communicating while wearing full PPE | HP11: I could barely hear anybody. It was really hard. | Using equipment to facilitate communication | HP34: Vocera is a communications system that you can have clipped on you or if you’re in the scrub role you can have it on the side and you can activate it by clicking it. With the N95 mask you don’t hear people. If you have Vocera then you can speak and people can hear. |
| PPE fogging up glasses | HP19: When I was wearing my spectacles when I was breathing out the air was misting up my spectacles. | Masks over glasses | HP20: We have been working on the last week on a modification. You have seen some reports in different countries about the use of a snorkel mask… and it seems to work much better, without fogging. |
| Needing additional equipment | HP3: Normally if we need something extra during the operation, someone just walks out of theatre, get its and then comes back in again, but we are not allowed to do because there are clean areas and dirty areas. | Equipment to aid communication with ‘runners’ | HP8: Well I brought some walky-talkies which are quite good which help with communicating from inside to outside of the room. So that is one problem. They are quite useful… the runner outside will have one and we have one in a plastic bag in the theatre. I actually bought them on eBay and everyone wants more now so I am buying some more which should arrive any day…. Shouting through the door or holding up signs is difficult. These work quite well actually. |
| Long periods wearing PPE | HP34: We realised people can’t do nine hours in a theatre with PPE on, wearing the N95 puts incredible pressure on people’s faces. | Changes in staffing | HP35: We have to do a team change, so we changed how we did things there as well. We started looking at team changes and how we would manage those, we’d send people home, knowing that in 4 hours, they’d be coming in to do a team change. |
