PHARM Podcast 002 – Seeing the Light
Key points of the podcast
- In the prehospital setting, personal equipment should be light, portable, small, cheap , easily replaceable and serve multiple functions
- A portable light source is essential, day or night, as a clinical examination tool and portable illumination
- My shopping list for a prehospital light source include : minimum 200 lumens intensity, LED, standard battery power(AA or CR123), hand carried or mountable with a clip, converts to head mounted illumination
- Hands free lighting is the way to go. Examine and do procedures like chest drain insertion or finger thoracostomies in low light conditions where your line of sight is illuminated!
- Transillumination or pan illumination using LED high intensity light source to find superficial non palpable veins. Traditionally used in paediatrics to find veins, this technique can be used in all age groups. Refer to accompanying demonstration video. Transillumination is technique of illuminating through the full thickness of a body part like a hand or foot. Pan illumination is the technique of localised soft tissue illumination allowing vessels to be shadow outlined locally. Yes with IO access in prehospital medicine, this is not so useful but still handy to know in case no IO or USS available. Useful areas to look for superficial veins with this technique are lateral infraclavicular area, medial lower humeral area, volar forearm, lateral neck, medial ankle and dorsum foot.
