The effect of needle diameter on pain during oocyte retrieval

Conclusion

Use of a thinner needle results in significantly and clinically relevant lower pain scores during oocyte retrieval, and patients in the reduced needle group requested significantly less analgesia during oocyte retrieval than patients in the standard needle group. Pain scores remained significantly lower up until 2 days after the procedure.

* Pain during OR, mean VAS (±SD): Reduced needle 4.3 (±2.0) vs. Standard needle 6.3 (±2.5).
** 1 of 3 in the randomized group for the standard needle.
