Transfusion-related acute lung injury (TRALI) is a rare but fatal complication of blood transfusion. However, it is frequently under-reported and not diagnosed. We reported a 32-year-old pregnant woman at 30/31 gestational weeks who developed acute respiratory distress and hemodynamic instability during transfusion in the post-operative period. Diagnosis of TRALI was made after excluding other possible causes of acute lung injury. We treated the patient with conservative treatment in the obstetrics emergency room based on the initial examination results and scheduled for an elective cesarean section (C-section). Transfusions of packed red blood cells were planned to increase the Hb level. The patient suddenly experienced shortness of breath during the transfusion with a relative risk of 30–36×/min. The patient was given 10 lpm oxygen via a non-rebreathing mask, and oxygen saturation was 86%. The patient’s blood pressure was 88/40 mmHg, and heart rate was 126×/min. The transfusion was immediately stopped. Fluid resuscitation with a crystalloid solution for hemodynamic improvement was given when the patient was intubated. After several treatments, the patient’s condition was getting better. On day 4, hemoglobin level increased to 9.1 mg/dL, hematocrit 27.6%, leukocytes 9.660/µL, and platelets 72,000/µL. Ventilator weaning was done gradually, and the patient was finally extubated on the 5th day of treatment.

| Background|| |
Transfusion-related acute lung injury (TRALI) is one of the severe complications of blood transfusion, the leading cause of the highest mortality. According to the Canadian Consensus Conference 2004, TRALI was defined based on the clinical and radiographic diagnosis as a recent ALI or acute respiratory distress syndrome (ARDS) condition that occurs during or within 6 h of completed transfusion. TRALI incidence is estimated to occur in 15% of transfused patients. Another study estimates the incidence of TRALI to be around 0.1% in transfused patients, however, up to 5–8% in groups of intensive care unit patients., According to a cohort study, the risk of transfusion reaction in post-partum patients is two-fold higher than that in non-pregnant women and those who had received three or more bags of red blood cells (RBCs) have a higher risk of developing TRALI.
| Case Report|| |
A woman, 32 years old, was referred from a district hospital with active vaginal bleeding. She is currently pregnant, a second child at 30/31 gestational weeks with placenta accrete and severe oligohydramnios. The patient had no history of hypertension and diabetes mellitus.
The patient’s condition was stable when examined at obstetrics ER at RSUD Dr. Soetomo. From the primary survey, patient’s airway was free, vesicular breath sounds were normal, and vital signs remained stable. The warm perfusion was obtained with a capillary refill time (CRT) of <2 s. At the same time, uterine fundal height was found following gestational age. Scanty active vaginal bleeding was found.
The patient received conservative treatment in the obstetrics ER based on the initial examination results. Dexamethasone 2 × 6 mg i.v. was given for lung maturation. The patient was scheduled for an elective cesarean section (C-section). However, on the 3rd day of conservative treatment, active vaginal bleeding occurred; hence emergency C-section was performed as soon as possible [Table 1].

The operation lasted for 4 h, and a hysterectomy was performed. Estimated blood loss during the operation was 4200 mL, about 93% of the patient’s estimated blood volume. The patient was given five bags of whole blood (WB), 1000 mL Gelofusine (B Braun, Indonesia), and 3500 mL of Ringer’s lactate and normal saline during the operation. No transfusion reaction was found. After the operation, the patient was admitted to the intensive care unit.
Postoperative day 0, the patient breathed spontaneously, respiratory rate 20×/min, SpO2 98% with 3 lpm oxygen via nasal cannula. The patient was fully aware, blood pressure 115/62 mmHg, heart rate 112×/min, and temperature 37.2oC. The patient underwent laboratory examination immediately after surgery.
Transfusion of packed RBCs (PRBCs) was planned to increase the Hb level. The patient suddenly experienced shortness of breath during the transfusion with a relative risk of 30–36×/min. The patient was given 10 lpm oxygen via a non-rebreathing mask (NRM), and oxygen saturation was 86%. The patient’s blood pressure was 88/40 mmHg, and heart rate was 126×/min. The transfusion was immediately stopped. Fluid resuscitation with a crystalloid solution for hemodynamic improvement was given when the patient was intubated. Also, a nasogastric tube was inserted [Table 2].
The patient breathed on a ventilator with pressure-controlled ventilation mode: pressure control at 18 cm H2O, positive end-expiratory pressure at 8 cm H2O, fraction of inspired oxygen (FiO2) 60%, respiration rate 20/min, and the vital signs were as follows: blood pressure of 108/72 mmHg, heart rate 112×/min, and warm perfusion with CRT less than 2 s. Norepinephrine 100 ng/h was given via infusion pump. Methylprednisolone 125 mg was given, besides fluid infusion and analgetic. Urine output in the last 3 h was 150 mL. The patient then immediately underwent a chest X-ray examination [Figure 1].
On the first day of treatment, the patient was still on the ventilator and under sedation. Vital signs were within normal limits, with norepinephrine 50 ng/h. Nutrition was started enterally and through maintenance infusion. The laboratory examination results showed that the hemoglobin level dropped to 6.1 mg/dL, hematocrit 19.5%, leukocyte 10,180/µL, and platelets 51,000/µL. Blood gas analysis showed average results. The patient was considered for transfusion with leukodepleted PRBCs.
Sedation was stopped on the second day, and Glasgow Coma Scale was 3 × 5. Norepinephrine administration was discontinued. Two bags of leukodepleted PRBCs were transfused safely. Evaluation on the third day of treatment showed that the hemoglobin level increased to 8.8 mg/dL, hematocrit 27.2%, leukocytes 9.660/µL, and platelets decreased to 19,000/µL. The patient then received a transfusion of thrombocyte concentrate at a dose of 10 mL/kg body weight.
The patient’s condition was getting better. On day 4, the hemoglobin level increased to 9.1 mg/dL, hematocrit 27.6%, leukocytes 9.660/µL, and platelets 72,000/µL. Ventilator weaning was done gradually, and the patient was finally extubated on the 5th day of treatment. Serial chest X-ray evaluations while the patient was in the intensive care unit are shown in [Figure 2].

| Discussion|| |
TRALI is a complex clinical syndrome that arises after transfusion of fresh frozen plasma, platelets, or PRBCs. TRALI occurs approximately once in every 5000 transfusions. However, the following years showed that numbers rose to 1 case in 4000 U transfused.
The vast majority of TRALI cases after the transfusion of plasma are associated with antibodies in the transfused component. These antibodies are directed against human leukocyte antigens (HLAs) class I and class II or human neutrophil antigens (HNAs) present on the recipient’s cells. Antibodies to HLA class II and antibodies to HNA-3a are most frequently associated with TRALI. A two-hit hypothesis applies in this clinical syndrome. Neutrophil sequestration occurs in the pulmonary vasculature, and neutrophils activate to damage the endothelial layer, causing leakage of protein, and fluid into the alveolar space became pulmonary edema. Although it is known that a trace amount of plasma triggers TRALI pathogenesis, the relationship between the administered dose and the severity is not particular.
TRALI can be diagnosed by clinical and radiographic diagnosis and is not dependent on the results of a laboratory test or pathophysiologic mechanism. The chest radiograph should show bilateral infiltrates that may be patchy, homogeneous, diffuse, or asymmetric and suggestive of alveolar or interstitial disease. Our patient chest X-ray showed bilateral pulmonary infiltrates, suggesting pulmonary edema.
Hypoxemia in ALI can be defined as a ratio of the partial pressure oxygen to the fractional inspired oxygen concentration (PaO2/FiO2) of less than 300 mmHg or as oxygen saturation <90% when a patient is breathing on room air. Oxygen saturation of our patient remained at 84% despite NRM 10 lpm, and PaO2/FiO2 showed 201 mmHg. The patient can develop a body temperature greater than 37°C or hypotension. However, there was no significant increase in body temperature in our patient.
Differentiating TRALI from transfusion-associated circulatory overload (TACO) challenges clinicians. The National Healthcare Safety Network defined TACO as pulmonary edema primarily related to circulatory overload, including three or more of the following within 6 h of transfusion: acute respiratory distress, radiographic pulmonary edema, elevated central venous pressure, evidence of left heart failure, positive fluid balance, and elevated B-type natriuretic peptide. Some patients will have a history of congestive heart failure, decreased left ventricular ejection, or diastolic dysfunction. Clinical evidence of hypoxemia in our patient who has not shown hypertension related to pulmonary edema or the left atrium led us to diagnose as TRALI.
There is no specific treatment for TRALI. Immediately, transfusion should be stopped, oxygen should be administered, the intravenous line should be kept open, and supportive therapy should be done. The patient’s vital signs should be monitored and recorded at 15-min intervals. In this case, we immediately stopped the transfusion after our patient experienced respiratory distress and gave supportive treatment, as explained earlier. In most cases, mechanical support is required., A low-tidal volume strategy is essential to minimize additional ventilator-induced lung injury. However, we used a normal-tidal volume strategy for our patients.
We administered methylprednisolone 125 mg i.v. However, the efficacy of steroids is still controversial. High-dose steroids have been used, partly because of the assumption of an immunological cause, but there is no direct evidence of benefit. Administration of diuretics is detrimental and should generally be avoided, as the pulmonary edema is not due to fluid overload. Hence, we did not administer diuretics because we did not discover the signs of fluid overload in our patient. A post-transfusion blood sample should be drawn and sent to the laboratory.
| Conclusion|| |
TRALI is a severe complication of transfusion. It is an underestimated healthcare problem. The effort to further decrease the risk of TRALI needs increased awareness of this syndrome among physicians. Appropriate and adequate supportive management will lower the morbidity and mortality of TRALI incidences.
