Norman Bethune’s portable blood-transfusion equipment

Norman Bethune’s portable blood-transfusion equipment was the mobile centerpiece of a new refrigerated-blood service in Madrid. Fifteen backpack units allowed blood collected and stored in the city to be carried to wounded soldiers at the front, where Bethune used the equipment to perform the first successful transfusion of refrigerated blood. The apparatus turned a medical advance into a practical field service: a donor no longer had to be physically connected to the recipient, and treatment could be taken to casualties rather than limited to direct, body-to-body transfusion.

Design and preparation

Bethune and his collaborators arrived at an apartment at 36 Príncipe de Vergara Street and transformed its spacious rooms into a laboratory. Furniture, paintings, and carpets were removed to make room for equipment unfamiliar in Spain at the time: an Electrolux refrigerator, a large autoclave, and two enormous sterilizers. The former bedrooms became treatment spaces, while shelves and display cabinets held vacuum bottles, blood containers, infusion sets, syringes, microscopes, thoracic-surgery instruments, hematimeters, serum, and gas masks. The portable kits were not an incidental addition to this installation. They were the means of taking its work beyond the apartment and into wartime hospitals near the front.

The core of the field equipment consisted of fifteen backpacks, each containing a portable unit and additional bottles, containers of physiological saline and glucose solution, and a sterilized box of supplies. That box held a towel, forceps, a knife, a syringe, and suture thread. The arrangement joined transportable blood supplies with the implements needed for treatment, making each pack a compact extension of the laboratory. The people responsible for maintaining the residence—a cook, two maids, and a laundryman—had never seen such equipment; the narrator emphasizes that its appearance in Madrid was unprecedented not only for them but anywhere in the world.

From donors to the front

The equipment depended on a reliable supply of stored blood. The Canadian Institute of Blood Transfusion appealed for voluntary donors through newspaper advertisements and radio broadcasts. On 19 December 1936, even before the institute opened, a queue already extended around the corner. Donors gave half a liter while fasting; their blood was mixed with sodium citrate and labeled with the blood group, collection date, and donor’s identity. The refrigerated stock rapidly filled the largest refrigerator available, while volunteers continued to line up on Príncipe de Vergara Street.

On 23 December, Bethune’s team filled the portable equipment’s bottles with blood from all groups, loaded the backpacks onto a truck, and drove to the Hospital de Sangre de la Casa de Campo, at the front line. There Bethune examined soldiers who had been given up for dead and chose a young man suffering from hypovolemic shock after massive blood loss. The Spanish doctor treating him considered the case hopeless but allowed Bethune to try, remaining to watch because he expected the soldier to die regardless.

Bethune pricked the soldier’s finger, collected a sample with a glass rod, and identified his blood group. He then began transfusing the first bottle through a needle. The patient moved and opened his eyes, but his blood loss was so severe that Bethune administered a second bottle. Before the transfusion was complete, the soldier looked at him and smiled. The equipment made it possible to bring stored, appropriately selected blood to this patient at the hospital rather than depend on a donor standing beside him and connected directly by needles and tubing.

Consequences and continued use

The first rescue demonstrated the practical difference between direct transfusion and the portable service. Refrigerated blood could be collected in one place, kept in bottles, transported to a casualty, and transfused without a live donor being physically linked to the recipient. The narrative presents the method as easier, more convenient, practical, and effective than the direct procedure. That change made the packs not merely containers but the operational link between Madrid’s donor campaign and treatment at the front.

Bethune’s intervention at the Hospital de Sangre de la Casa de Campo revived twelve soldiers that morning. The first survivor’s name is not known. His comrades marked his return to life by putting a lit cigarette in his mouth; as he smoked, the hospital’s distress gave way to an outburst of joy and hope. Those present cheered Canada, Bethune, the Republic, the working-class struggle, and international solidarity. The episode gives the equipment’s technical achievement a human measure: the unnamed patient could participate in the celebration because the transfusion had brought him back from the brink of death.

The service continued after Bethune left Madrid to tour other fronts with his team. On 11 January, he visited the Hospital de San Carlos to say goodbye to the narrator, a physician who had helped with the work, and asked him to take charge of the mobile service. The institute itself was to continue operating with Spanish personnel. Within less than a month, the narrator had organized half a dozen mobile units while keeping his hospital post, and Dr. Quintanilla appointed him head of a transfusion service at San Carlos, established with a refrigerator donated by the people of Canada. The portable equipment thus belonged to a system that could be taught, replicated, and extended beyond Bethune’s own direct participation.

Significance in the novel

The apparatus is significant because it connects a specific material innovation to a wider collective effort. The refrigerator made preservation possible; the labeled bottles made stored blood identifiable; the backpacks carried it to the front; and the mobile teams brought the procedure within reach of patients who could not wait for conventional arrangements. The narrative stresses that this chain depended on donors from Madrid as well as Canadian support and medical organization. The equipment’s effectiveness therefore resides in a network of people and resources, not in an isolated invention.

The scene also gives the portable packs a narrative role beyond technical description. Their preparation occupies the former salons and bedrooms of a luxurious apartment, converting a residence into a working laboratory; their loading onto a truck carries that laboratory’s purpose into a frontline hospital. At the bedside, a needle, a blood-group test, and two bottles mark the reversal from a prognosis of death to a returning gaze and smile. The device is shown through its consequences: it lets medical care travel, and it makes an otherwise anonymous soldier’s renewed life the clearest evidence of what the new service can do.
