We mostly use the speed clips at work. But when I have a chance, I really enjoy working with the spider straps. Just last Friday, we responded to an assault and the patient had a basal skull fracture and pretty much all the bones in the face broken. He was drunk and quite violent and also on the second floor. The spider straps worked like a charm.
We use quick release straps here, spiders used to be the favourite but now they sit in the store room.
Straps work well & are fast if used correctly, a while back we had a large lady fall & suffered a lumber inj & # R NOF, she lived in an old county cottage with a narrow & very steep spiral staircase. We had to tip her onto her side then carry her upright down the stairs, all was fine with a top up of NO2
With chest straps crossed, a strap over pelvic region & a fig 8 around lower legs / feet.
