Your existing general purpose, or slit-leg sling, can most often be used to perform this transfer, as it does not cause any significant internal or external rotation of the hip. (please check with the manufacturer of your slings to confirm this.)
If the patient is arriving by stretcher, there is a risk that applying the sling might be a bit painful (particularly if there is a fracture or other injury to the hip). In order to minimize the pain and avoid possible exacerbation of the injury, we would suggest log rolling to the UNAFFECTED side and placing the sling under the patient as gently as possible. With proper technique, there should be no need to turn the patient onto the affected hip. If log rolling is not possible (narrow stretcher or exceptionally large patient), you might wish to use HandySheets to apply a sling to the patient. This eliminates the process of turning the patient.
Note: If the patient is in a wheelchair, you can also use the HandySheet for sling application. This avoids having the patient move forward (possibly causing pain) while allowing you to apply the sling safely and painlessly.
Finally, I have attached Liko™ Instruction Guides for you to read more about the log roll technique and sling applications using the Liko Universal™ Sling and the Liko HandySheet™ accessory.
