In customer words: "hello, we have a customer that has called me about some issues while using the kiwi.They are long time users of the product.They recently have had three babies that have had lacerations on the scalp caused by pop offs.This seems most likely caused by provider not following the vacca 5 step process.We are working on setting dates for a education workshop for the staff.We hope to have that completed in the next few weeks.My question is, should i fill out a complaint form? i have the lot number, but they discarded the kiwi (s) that were involved in the deliveries." "dr used kiwi for an operative delivery.Dr experienced a pop-off and the result of the pop-off was a laceration to the infant scalp.This happened on three different occasions with three different kiwis all from the same lot number.".
