Customer service conducted troubleshooting including verifying user was using correct kit components; verifying user was washing parts according to instructions for use; verifying user was using dry parts when pumping; verifying user was not washing or drying tubing on pump; verifying there was no milk backup; verifying user didn't have a heavy letdown; verifying user was in correct pumping position; and verifying breast shield size.In follow up with a complaint handler on 12/28/2023, the customer indicated that she developed mastitis on 11/11/2023 and was hospitalized.Her mastitis is currently healed and gone.She has not had time to try the new pump yet.Based on the results of our internal investigation (reference number ca11-001), it cannot be definitively concluded that the pump caused or contributed to the customer¿s mastitis.The estimated incidence of mastitis in lactating women, whether using a breast pump or not, according to published clinical literature can be as high as 33%.In fact, clinical guidelines suggest the use of a breast pump to facilitate withdrawal of breast milk during bouts of mastitis.(b)(4).Mastitis is usually a benign, self-limiting infection with few consequences for the suckling infant.The risk of mastitis is higher among women who have breastfed previously, especially those with a history of mastitis.Riordan & wambach, 4th ed.P.294: breastfeeding and human lactation.However, in this case, the mother¿s mastitis required prompt medical attention for pain relief and prescription antibiotics to avoid progression to overwhelming sepsis.
