Cliff Reid - Advice to a young resuscitationist

Dr Cliff Reid of Greater Sydney HEMS is probably one of the finest exponents of not only resuscitative science but also in transmitting ideas via talks/presentations. This plenary from SMACC Chicago last year gives us important insights into:

  • overconfidence
  • following up
  • changing oneself and systems when thigns go wrong
  • other specialists and using their skill and experience
  • risks and rewards of being in this field

He has his own channel here for other inspiring talks on resuscitation.

Webucation 29/5/16

Webucation this month comes from the realms of paedatric surgery, urology and even on some tele-medicine. Remember to visit and credit the original posters.

  • Sepsis-3 - This is need to know classification for all who deal with this disease
The last link is a must read for those in our speciality. For it is said many a time that the 2 things that we deal with mostly in our career are related to vascular problems and sepsis. So be good at them.

Another win for U/S

Here's a good one from JournalWatch. Its encouraging to see some myth-busting and new standard setting coming into the mainstream.
Original study lives here.

No Need for Chest X-Ray After Ultrasound-Guided Right Internal Jugular Lines?

Very few complications were picked up by routine chest x-ray at a large academic hospital system.

For decades, dogma has been that chest x-ray should be performed to confirm placement of all internal jugular (IJ) central lines, despite evidence that ultrasound can significantly reduce complication rates. These authors retrospectively assessed detection of complications by routine chest x-rays obtained after ultrasound-guided placement of right IJ central lines in adults at an academic tertiary hospital system.
During 2014, a total of 1322 right IJ central lines were placed with ultrasound guidance in emergency departments, intensive care units, and general wards. Overall, 97% of attempts were successful. Chest x-ray detected 1 (0.1%) pneumothorax, 13 (1.0%) misplaced catheters that required repositioning, and no arterial placements.


For ultrasound-guided, right IJ lines, these findings suggest that routine chest x-ray may eventually be replaced by ultrasound to assess for placement complications. The findings also demonstrate that resuscitation should not be delayed by waiting for the confirmatory x-ray. The case is closed when it comes to the requirement for using ultrasound for IJ line placement. If you aren't using it, be prepared for the difficult conversation explaining why.

Tupac on nurses

Having learnt some hard lessons when I was fresh and having been on the treatment side of medicine, I can attest to the truth of the following video. This is a never ending shout out to the nurses who embody the spirit of healing.

How fluid is your practice?

Here's another talk from SMACC Chicago last year from luminaries in teh critical care field debating some thorny issues.
CAUTION: Some profanity and dogma changing views. Might make you think about what you're doing everyday!
Kudos to the SMACC team and animators for this vid.

The eyes have it

Prof Larry Mellick posts great medical vids on his Youtube channel. Here's his recent posts on opthalmological emergencies. 
Great tips include:
  • Grading and complications of hyphema
  • Pathophysiology of corneal ulcers
  • Distinction of periorbital and orbital cellulitis
This is modern learning at its finest and make a point to "like" and subscribe to his channel.

Not another headache!

Here is another of our EM residents - Gayathi Nadarajan
She discusses 3 cases of non-traumatic headaches and their diagnoses with a focus on the evaluation of a patient with acute headache in the ED

Case 1:

A 19-year-old Chinese lady with a background of haemolytic anemia presented in the middle of the night with a 3-day history of the worst headache of her life with neck stiffness. On examination, besides profound neck stiffness, there were no other neurological findings.


CT scan: Acute subarachnoid hemorrhage in the left frontal lobe and acute subdural hemorrhage over the left frontal temporal convexity. Midline shift of 4mm to the right.

4 vessel angiogram : There were no aneurysm

Platelets: normal

All investigations were not completed as patient discharged against advice. Hence no cause was found for her non-traumatic bleed.


Case 2

33-year-old Malay lady with no medical problems as such, presented to the ED with a sudden onset, thunderclap headache, associated with vomiting, left ankle weakness and foot drop. She also noted bruising over her left ring finger tip a few days ago.

Examination revealed a left foot drop and weak ankle inversion with sensory deficit over the dorsum of the foot.

CT brain: Basal cisterns & pre-pontine SAH, small ICH, superior cerebellar arachnoid cyst & earl communicating hydrocephalus.

CT angiogram: 3mm aneurysm at epicenter of left PCA branch

4 vessel angiogram: Possible mycotic aneurysm of P4 segmental branch of left posterior cerebral artery likely septic emboli or seeding from IE.

Unsuccessful in coiling the aneurysm

She than had craniotomy and excision of the aneurysm.

Transthoracic echocardiogram: bileaflet MVP with severe MR and IE 1.4cmx1.0cm anterior leaflet and 0.5cm posterior leaflet vegetation

Hence a diagnosis of mycotic aneurysm from infective endocarditis was made.


Case 3

A 66-year-old independent and active Chinese gentleman presented to the emergency department as his blood pressure was noted to be high. He has hypertension and hyperlipidemia He routinely measures his blood pressure once a day and yesterday it was as high as 172/70 after measuring for about 3 times. His children than convinced him to come to the ED for a ‘check-up’ as they were worried about the high blood pressure.

He also had a headache for the past 3 days, which was resolving. It wasn’t the worse pain he ever felt but it was the first time he had such a headache. There were no associated or aggravating symptoms with the headache.

On examination, he was very well and had no neurological deficit. His blood pressure at triage was in fact 149/73.

In view of the new onset of headache in his age group, a CT head was ordered.


CT brain: Hyperdense enlargement of the left transverse and sigmoid venous sinuses suspicious for venous sinus thrombosis, complicated by an area of venous infarction & haemorrhage in left parietal lobe

MRI venous: Cerebral venous thrombosis involving the entire left transverse and sigmoid sinuses extending to the proximal internal jugular vein. There is involvement of the left superior and inferior petrosal sinuses and secondary left temporoparietal venous infarction with haemorrhage.

No identifiable cause on MRI.

Patient was diagnosd with cerebral venous thrombosis. He was investigated and started on anticoagulant.



Don’t worry… you are not alone….

While in the consult room, it is normal to have the sinking feeling at the bottom of our stomachs when you are faced with yet another patient with a headache. We know that the headache consult will be a long one indeed. A thorough history taking and examination is crucial to avoid missing an intracerebral bleed.

Headache red flags

For the first 2 cases, the severe, thunderclap headache was a red flag. However, for the 3rd case, it was not obvious as the triage complain was ‘high blood pressure’. But his pressure at triage was fine!

The red flag only came out from ‘digging out’ the history from him. He said “By the way doctor… I did have this headache for the pass 3 days… it actually is getting better. The severity was probably the worst when I measured my blood pressure yesterday. I don’t normally suffer from headaches, but neither would I say this is the worse pain I ever felt!” The red flag was the new onset of headache in a patient above the age of 40

Discussion and more algortithms!!!

The aim of these cases is to:
  • Re-emphasise the value of good history taking in order to avoid missing out a deadly diagnosis such as a intracerebral bleed
  • To revisit red flags that may suggest a bleed
  • Despite the triage complain, ALWAYS ask the patient why they turned up in the ED on that particular day and at that particular time
I will end off with some algorithms, to remind us of headache red flags.
