A 26 yr old woman with a suspected ruptured ectopic pregnancy is rushed to theatre in haemorrhagic shock. The patient has a history of IVDU with a naltrexone implant. The team in the emergency department have been unable to get vascular access. She has a heart rate of 150/min and a BP of 75/45. She is now very distressed and unco-operative from both the abdominal pain but also the repeated painful attempts at vascular access with large needles by lots of different healthcare staff!
Join Graeme and I as we discuss the various different options for gaining vascular access to allow resuscitation, but also induction of anaesthesia so definitive surgery can occur.
We discuss the following various options:
- USS guided peripheral IV access
- Intraosseous drills
- External Jugular peripheral IV cannulation
- Internal Jugular peripheral IV cannulation – “The Rapid IJ”
- Large bore central cannulation (eg MAC line, swan sheath, haemodialysis catheters) – usually Internal jugular (IJ) and subclavian (SC) or Femoral.
- Surgical cut-down – saphenous or brachial.
Graeme even discloses that he has trialled unsuccessful sternal intraosseous placement in the past – sounds like an interesting case we should perhaps delve into more detail on at another time!!
Bottom line – shorter and wider bore catheters are better for rapid fluid resuscitation.
The MAC line – note swan sheath, haemodialysis or other large bore central catheters will also work:
Youtube / Podcasts Discussing this topic:
A great course to learn emergency procedures for use in trauma care run by the critical care trauma team at The Alfred in Melbourne. Check out their description of vascular access in particular their detailed description of the technique for emergent placement of the large bore MAC line in the subclavian vein.
A great discussion on the placement of large bore femoral catheters.

These are ABG’s from four different individuals? What do these represent?
First correct answer gets kudos and a mention on the next podcast!
