Comparative analysis of platelet concentrates prepared after two hours and overnight storage of buffy coat at room temperature.

INTRODUCTION: The overnight storage of the buffy coat (BC) at room temperature has logistic and operational advantages for the blood centre. The present study aimed to evaluate the impact of an overnight hold (stored) of BC at room temperature in comparison with the 2-hour hold (fresh) of buffy coats on the platelet concentrate (PC) characteristics. METHODS: A total of 60 BCs were included in the study, 30 PCs (fresh) were prepared after two hours holding time of the BCs and the other 30 PCs (stored) were prepared after the overnight BC storage at room temperature. The primary endpoint of PCs evaluation was the platelet yield, volume, pH, WBC count, RBC count, and platelet swirling in the PC and the secondary endpoints were glucose concentration, lactate, LDH, and sterility of the PCs. All the tests were performed on the day+1 of the blood collection. RESULTS: There was no difference concerning the volume, RBC count, and swirling between the two groups (P>0.05). The PCs from the fresh BC had higher pH and glucose concentration (P<0.05). On the other hand, the overnight hold of BC produced higher platelet counts, WBC counts, lactate, and LDH levels (P<0.05). All the 60 PCs did not record any bacterial growth on the culture media for the sterility results. CONCLUSION: The overnight hold of BC produces a higher platelet yield with higher storage lesions. This may also allow better supervision, ensuring better quality control.

Challenges in platelet inventory management at a tertiary care oncology center during the novel coronavirus disease (COVID-19) pandemic lockdown in India.

The novel coronavirus disease (COVID-19) has been declared a pandemic by the world health organization and to limit the spread of the disease, many countries in the world, including India, had enforced a lockdown. Despite no restriction over the platelet donation activities, plateletpheresis donors became apprehensive regarding the possible risk of spread of the COVID-19 during the platelet donation and in the hospital premises. Many of them started hesitating for platelet donations. With this, the blood center started having an acute shortage of platelets. Various confidence-building steps were implemented by the blood center to promote voluntary plateletpheresis. The blood center staff and individual donors were educated to prevent the spread of COVID-19. The donor organizations and plateletpheresis donors were informed about the steps to be taken by the blood center during the donation and necessary steps for the prevention of the possible spread of COVID-19. With the help of these measures, the confidence of the individual platelet donors and the donor organizations was restored in the blood center and regular plateletpheresis was continued. These measures may also be useful to other blood centers in the COVID-19 pandemic and this experience may be useful if a similar pandemic lockdown happens in the future.

Organization of the outdoor blood donation drives amid novel coronavirus pandemic and national lockdown: An experience from a tertiary care oncology institution in India.

The conduct of blood donation drives became difficult amid novel coronavirus disease pandemic and national lockdown. Despite no restriction for the outdoor blood donation drives, voluntary blood donor organizations (VBDOs) and individual donors became apprehensive regarding the possible risk of spread of the infection during blood donation. Various confidence-building measures were taken to decrease this hesitation. Numerous preventive measures were taken at the blood bank and at the donation venue to limit the possible risk of the spread of infection. With the help of these measures, the confidence of the individual blood donors and the VBDOs was restored and multiple blood drives were organized.
