The state Medical Examining Board disciplined three doctors this week, including reprimanding a Waterbury obstetrician for failing to perform a timely Caesarean section in a case in which the infant died. Dr. John Kaczmarek also failed to assess the infant’s category III fetal heart monitors results on Aug. 10, 2014 at Waterbury Hospital, a consent order he signed with the board states. Category III results are considered abnormal and may indicate that the fetus is at risk of being deprived of oxygen. Kaczmarek also did not appropriately document his evaluation of the monitor results or his plan of care, the order said. The consent order does not detail what happened to the baby, but Christopher Stan, a spokesman for the state Department of Public Health (DPH), said Thursday that despite resuscitation efforts and a transfer to Yale New Haven Hospital, the baby died a day after delivery.
