Alternatives, and doing Nothing) was developed by Choosing Wisely UK and can be used as a framework for these discussions.
Without an alternative is there really a true choice? Some alternatives may come easily to our mind: surgical or medical management; chemotherapy or radiotherapy. But it is worth reminding ourselves to remain patient focussed – would a delay in treatment be an option? Would treatment in a different location be possible? These are not always natural considerations, but for a patient to be closer to family or feel well through a signi cant life event before starting treatment may be important. We are all driven to try and help our patients and it is not unreasonable to presume that surgeons offer surgery and oncologists offer chemotherapy because they believe it will bene t the patient. But for some individuals doing nothing may be the right decision. This may feel alien to us as healthcare

CLINICAL DILEMMA | What Would You Do? |
Many thanks to Ross Hofmeyr and Francois van Heyningen for this edition’s challenging case from Cape Town, South Africa: A 33-year-old woman with severe rheumatoid ar thritis is booked for elective bilateral temporomandibular joint replacement.
She is
wheelchair bound due to xed exion deformities of both hips and knees. Airway examination demonstrates that she is edentulous with an intergum mouth opening of 15 mm and has signi cantly limited range of motion of her neck. In addition to the presenting and surgical problems, she is currently in her third month of treatment for multidrug-resistant pulmonary tuberculosis, and has iron-de ciency anaemia (Hb of 6.7g/dL). She is frail but alert; nervous but co-operative.
What is your plan?

WHATWOULDYOUDO? DAS Expert Corner Airway Expert 1: Issues: 1. Everyone needs to agree that surgery is the right plan, particularly the patient - surgery needs to provide expectation of life quality improvement as it is extremely HIGH RISK. 2. Needs a nasal TT 3. Predicted Dif cult Intubation. Intra-oral airway rescue may be impossible, making eFONA risk higher. May have crico-arytenoid dysfunction secondary to RA 4. Predicted hypoxaemia + hypercapnia risk 5. Reduced oxygen carrying capacity. Strategy: 1. MDT to agree best timing with TB Rx and optimising haematology. Don’t see why there is a huge rush here, ie optimise chest so respiratory docs say that it’s as good as it gets; optimise Hb under haematology guidance 2. Cannot nd any reason NOT to perform ATI. Needs MDT to agree best personnel, time, venue, strategy etc 3. Mark the neck for potential eFONA 4. ATI:FB nasally with HFNO. Remi awake + LA. Small exible tube. Careful rail-roading as has RA which may involve glottis. Ideally i would like to visualise tube passage but this is tricky with 15mm MO so probably just [a] involve expert and [b] take care! 5. Surgeon ready to perform eFONA if control lost 6. Safe awake extubation assuming airway is safe. Again awareness that may have RA of larynx. Probably HDU post-op with clear escalation plan agreed between anaes/ICU + OMFS
Airway Expert 2: 1.
It’s an elective case which should be delayed as she has a Hb of 6.7. She should have oral or parenteral Iron and her treatment should be guided by monitoring Hb and serum iron concentrations.
2.
When she has an appropriate Hb she should have an elective ATI - exible bronchoscopy nasally with the team in PPE if using Opti ow (because of her TB).

Airway Expert 3: This is the case of a frail, medically complex patient with a predicted dif cult airway with an infectious disease posing risks to staff. First, I would work to ensure that the patient is medically optimised. This patient sounds like she may need to have her anaemia addressed with pre-operative i.v. iron ± transfusion. This is important because she has concurrent pulmonary pathology and is at risk of hypoxaemia, thus oxygen delivery must be optimised. Airway management is about oxygen delivery to end organs, and we must optimise all steps along this ladder. In terms of airway management, once the patient is optimised, there are clear indications that this patient must avoid hypoxia and has a dif cult airway, therefore awake tracheal intubation (ATI) is indicated. This patient would need counselling for it, and a clear discussion and consent. My technique would follow the DAS ATI guidance: ✦
Oxygenation: HFNO 50-70 l/min
✦
Topicalisation: Lidocaine 10% spray to oropharynx. Co-phenycaine to the nose. Ensure dosing are weight-adjusted.
✦
Sedation: Very judicious use of remifentanil only (TCI 2-3 ng/ml)
✦
Procedure: exible bronchoscope, size-appropriate Portex blue nasal tube (≤6.0mm). Induction of anaesthesia after a two-point check (CO2, visualisation of tube above the carina).
Airway Expert 4: This is a really good case to discuss as lots of our patients need more than airway management. The patient needs sorting out rst (elective case): I. The TB II. The anaemia - cause and treatment III. The extent of the RhA - has anyone imaged her neck, checked it for stability/ subluxation Next: What do the surgeons want and need in terms of access - how can that be accommodated anaesthetically? Finally STOP, plan and prepare for airway management (obviously taking account of the patient’s weight) and with a skilled second anaesthetist in attendance Personal preference would be for a nasal ATI appropriate topicalised and sedated (but check the albumin before setting off given the active infection). As always I would use HFNO, it just makes it easier. Tube selection - I have done it with both narrow bore armoured and soft ‘ivory’ tubes, both have their place but I always use merocele packs to stop nasal ischaemia.

Airway Expert 5: 1. I would ask for a multidisciplinary team meeting which would include the surgical team, respiratory team and myself to decide if the case can be delayed until he patient is optimised for surgery with regards to treatment for TB and her anaemia. 2. I would also like to have an informed discussion with the patient to establish the risks and bene ts of the timing of the surgery. 3. Ideally I would like her to have completed her TB therapy and start iron replacement therapy prior to surgery. 4. With regards to airway management this patient has limited mouth opening and limited neck movement therefore my plan would be to intubate using an ATI technique as per DAS ATI guidelines, in particular focusing on ef cient and rapid intubation with minimal coughing by using remifentanil TCI as the sedative agent. 5. All members of staff involved in the case should be made aware that the patient has multi-drug resistant pulmonary TB, or that she has recently completed
therapy for this (depending on the
timing of the case). 6. Due to the patient's history of multi-drug resistance pulmonary TB I would minimise the number of people present in theatre during intubation and extubation episodes, whilst taking full respiratory PPE precautions. 7. Post operative care also needs to be considered as the patient will certainly be a more dif cult intubation if required, so a robust airway plan will need to be in place and the patient should be admitted to ICU on the rst post op night.
Airway Expert 6: This is an elective case with several important considerations along with an extremely challenging airway. It is likely to be a long case with issues around airway management, multidrug resistant TB, iron de ciency anaemia and frailty of the patient. Positioning the patient on the operating table for a long case with xed exion deformities will also require planning along with other members of the team. If it was an urgent procedure, I would opt for an awake nasal
breoptic intubation for airway
management. If the patient is fully compliant with the TB medications, the risk of infection is low however I will consider wearing a personal protective mask based on infectious control teams advice. Since this is an elective procedure, I will ask for a proper MDT discussion around treating her iron de ciency anaemia, optimisation around her weight and seek advice on her ongoing TB treatment and an accurate assessment of spread of infection to health care providers. I will also discuss if the case can be done as a unilateral TMJ replacement to reduce the intraoperative time. I will ask for physio input regarding positioning of the patient for the procedure and arrange HDU care postoperatively. I will also involve the nutritional team to optimise her preoperatively. I will have a detailed discussion with the patient as well regarding the risks involved for this procedure.

THOUGHTS FROM OUR CASE SETTER | Ross Hofmeyr and Francois van Heyningen |
Issues Identi ed: 1.
Dif cult airway
✦
Limited mouth opening and edentulous
✦
C-Spine instability
✦
Limited head extension; some exion
✦
Unable to exclude laryngeal involvement of RA
BVM
– would likely be possible with the use of OPA or NPA
LMA
– limited mouth opening would make passing of LMA very challenging
Asleep DL/VL – likely not possible due to points above ATI
– best option dependent on quality of sedation/topicalisation and patient cooperation
FONA
- access to cricothyroid membrane adequate
2.
Risk of environmental contamination with MDR TB during aerosolizing airway procedures
3.
RA-associated end-organ damage and severe anaemia
Our Plan: Plan A - awake tracheal intubation using exible bronchoscope: ✦
Thorough topicalization using hypersonic nebulizer with 4% lignocaine/adrenaline mix, as well as direct ‘spray-as-you-go’ topicalization of vocal cords during endoscopy
✦
Ultrasound guided identi cation of cricoid membrane, transmembrane placement of 20G IV cannula and sub-laryngeal topicalization. Cannula left in place as landmark for FONA in an emergency
✦
Dexmedetomidine sedation with slow loading dose and subsequent infusion
✦
Nasal intubation with head in neutral position/limited C-Spine movement
✦
Once ETT secured and coupled to anaesthetic machine, bolus of Propofol as induction
Plan B - perform BVM ventilation with or without an OPA/NPA if the patient became apnoeic. Intubation could be reattempted after optimization of position and conditions Plan C - quick attempt at insertion of a slim-pro le LMA Plan D - FONA, with a cricothyroidotomy set nearby and surgeons in theatre on standby ✦
Reassessment of mouth opening after induction – VL blade carefully passed as reassurance that VL with bougie can be used in an emergency, including at extubation
✦
All staff in theatre aware of exposure risk and wearing appropriate PPE
✦
Care taken with patient positioning
✦
Transfused 2 units of red-cell concentrate intraoperatively

being the same in terms of function and performance. Video laryngoscopes can be shaped at a more acute angle than traditional DL blades that effectively allow them to look around the natural curve of the airway to allow the video camera to see the larynx without having to create an almost straight direct line of sight to the user. Some VL systems have both angulated blades and the traditional standard Macintosh and/or Miller DL blades. There is no agreed upon nomenclature for the different types of VL blade, but it can help to think of them as standard blades (where DL can be performed, as well as indirect VL) and non-standard, hyperangulated blades (where usually only indirect VL can be performed). In
A consistent feature of the data we have is that smaller children are more likely to be dif cult to intubate and to have more complications, as well as having lower success rates when advanced techniques are used to intubate them than is commonly seen in adults. Infants and neonates were identi ed as a particularly vulnerable group, hence the PeDIR collaborative designed a multinational, randomized clinical trial designed to compare traditional direct laryngoscopy with standard blade indirect video laryngoscopy in infants (the VISI trial)11. This study looked speci cally at patients who were not anticipated to be dif cult to intubate and was designed to be re ective of anaesthetic practice in infants

Videolaryngoscopy versus direct laryngoscopy for adults undergoing tracheal intubation. ✦
Hansel J, Rogers AM, Lewis SR, Cook TM, Smith AF. Videolaryngoscopy versus direct laryngoscopy for adults undergoing tracheal intubation. Cochrane Database of Systematic Reviews. 2022; 4: CD011136. doi: 10.1002/14651858.CD011136.pub3. PMID: 35373840; PMCID: PMC8978307.
The debate over if videolaryngoscopy is superior to direct laryngoscopy was very much brought back into to the spotlight when this updated Cochrane Review was published in April. A fantastic piece of work for which the authors must be commended. First published in 2016 this updated review in looked at the growing body of evidence comparing videolaryngoscopy and direct laryngoscopy. The review collected data on the following outcomes: failed intubation; hyperaemia; successful
rst attempt at tracheal intubation;
oesophageal intubation; dental trauma; Cormack-Lehane grade; and time for tracheal intubation. It compares 3 types of videolaryngoscopy (Macintosh style, Hyperangulated and Channeled) versus direct laryngoscopy. The authors conclude that “videolaryngoscopy likely provides a safer risk pro le compared to direct laryngoscopy for all adults undergoing tracheal intubation.” While some on social media have been referring to this review as the end for direct laryngoscopy, the authors must also be commended for their balanced approach where they have been simultaneously advocating for a shift towards universal videolaryngoscopy (based on the evidence) and presenting the bene ts of direct laryngoscopy using videolaryngoscopes. We suspect the debate is now likely to shift towards comparing devices and the question of which device is best?

Videolaryngoscopy vs. direct Macintosh laryngoscopy in tracheal intubation in adults: a ranking systematic review and network meta-analysis. ✦
de Carvalho CC, da Silva DM, Lemos VM, Dos Santos TGB, Agra IC, Pinto GM, Ramos IB, Costa YSC, Santos Neto JM. Videolaryngoscopy vs. direct Macintosh laryngoscopy in tracheal intubation in adults: a ranking systematic review and network meta-analysis. Anaesthesia. 2022; 77: 326-38. doi: 10.1111/anae.15626. Epub 2021 Dec 1. PMID: 34855986.
There are a number of different video laryngoscopes available for use today. Most manufacturers offer a range of blades in different sizes including hyperangulated and paediatric blades. Departments may have either a single option or multiple options available for use and there has been no clear evidence of superiority of a single device or manufacturer. In this recently published paper, the authors carried out a systematic review with network metaanalyses to rank video laryngoscopes for orotracheal intubation performance compared with the Macintosh direct laryngoscope in adults. The primary outcome was the risk of failed intubation with the devices, with the secondary outcomes being: failed rst intubation attempt; failed intubation within 2 attempts; dif culty of intubation; percentage of glottic opening seen; dif cult laryngoscopy; and time to intubation. This was a well thought out and conducted piece of work looking at a question clinicians are seeking the answer to. Although the authors found statistical and clinical evidence of the bene ts of videolaryngoscopy over direct laryngoscopy they were unable to identify statistically signi cant differences between the various videolaryngoscopes assessed. An interesting read to see the comparative scores of different devices. Worth a look to see how did the device you are most familiar with/prefer faired.
