The high number of injuries from car accidents on Bulgarian roads this summer has drained the blood banks, boosting an already existing illegal blood trade, according to doctors.
"In most hospitals the blood situation is tragic in August," Balina Bozova, head of the transfusion unit at a hospital in the southern town of Haskovo told the Standard newspaper.
"Now our ward has only minimum supplies of blood for every type and if we are faced with a major situation where large quantities of blood have to be given to patients, we will have trouble coping with it."
This has forced leading Bulgarian hospitals to postpone scheduled surgery as there is neither enough blood nor enough free beds in intensive care wards.
"We hardly manage to cover the emergencies let alone planned operations" with existing blood supplies, the head of the National Transfusion Haematology Centre, Andrey Andreev, told AFP.
"We are postponing scheduled operations because there is no room in intensive care because of crash victims," the director of the Military Medical Academy Stoyan Tonev also told journalists recently, adding that the situation on Bulgaria's roads was a "real disaster."
According to Andreev, an emergency patient needs three times as much blood as a regular patient during surgery.
"Sometimes we gave them less than the necessary, but they lived," he said.
Every year, an average 1,000 people are killed and 10,000 injured on Bulgaria's roads, a figure that a recent World Bank road safety study deemed too high for a country of 7.6 million people, and which exceeds the European Union average by around 20 percent.
