A biomedical technician (bmt) from a hospital's hemodialysis unit reported an event of blood loss, which resulted in medical intervention and a prolonged hospital admission.Upon follow up with the unit's nurse, it was reported that towards the end of treatment, the venous line became disconnected from the patient's catheter access site, resulting in patient blood loss.The patient's estimated blood loss (ebl) was noted as being approximately 600ml.The machine did not alarm.The patient exhibited a decreased level of consciousness and did not respond when the nursing staff attempted to gain the patient's attention.At this time, 600ml of normal saline was administered.The patient came-to and reported a feeling of "wooziness" for approximately 1 minute, and then felt better.The patient's hemoglobin was sampled, and came back normal.The patient was set to be discharged on the day the event occurred, however, the decision was made to keep the patient overnight.The following day, the patient's hemoglobin was sampled again, this time reading 6.6.The patient was transfused with an unknown amount of blood, and then discharged from the hospital.The patient was re-admitted to the hospital 2 days later for an unknown reason.Although requested, no further information was made available.
