3.6 Stuck needle
After insertion, one may find it difficult or impossible to rotate, lift and thrust, or even to withdraw the needle. This is due to muscle spasm, rotation of the needle with too wide an amplitude, rotation in only one direction causing muscle fibres to tangle around the shaft, or to movement by the patient.
The patient should be asked to relax. If the cause is excessive rotation in one direction, the condition will be relieved when the needle is rotated in the opposite direction. If the stuck needle is due to muscle spasm, it should be left in place for a while, then withdrawn by rotating, or massaging around the point, or another needle inserted nearby to divert the patient's attention. If the stuck needle is caused by the patient having changed position, the original posture should be resumed and the needle withdrawn.
