In an unprecedented medical response, the Cell Production Centre at Lausanne University Hospital has mobilized its entire team to cultivate life-saving skin grafts for victims of Switzerland’s devastating New Year’s bar fire. The specialized facility—Europe’s largest of its kind—has received 15 urgent requests for artificial skin cultivation specifically for Crans-Montana fire survivors, a number that typically represents three-quarters of their annual caseload.
The tragedy at Le Constellation bar on January 1st resulted in 40 fatalities—primarily teenagers—and left 116 injured, with 80 patients still hospitalized across Switzerland and neighboring countries weeks after the incident. According to Laurent Carrez, the center’s pharmacist technical manager, medical staff are working seven days weekly to address the overwhelming need.
This cutting-edge medical process begins with collecting healthy skin samples from burn victims themselves to prevent tissue rejection. Through sophisticated laboratory techniques, technicians can transform a mere 10 square centimeters of original tissue into substantial grafts covering up to 7,800 square centimeters—approximately the surface area of three human backs.
The production occurs in controlled cleanroom environments where specialists meticulously nurture skin cells in nutrient-rich solutions. The current phase involves multiplying keratinocyte cells, which naturally form layered tissue over approximately three weeks. These laboratory-grown skins lack hair follicles and sweat glands but provide critical protection once grafted.
As explained by severe burns specialist Olivier Pantet, such extensive tissue cultivation becomes essential when patients have lost over 50% of their skin surface. While awaiting grafts, medical teams utilize temporary measures including specialized dressings, donor skin, and even fish skin applications.
The grafting process itself carries significant challenges, with an 80% success rate considered excellent outcomes. Post-operative care involves meticulous environmental control in high-humidity rooms maintained at 30°C (86°F), followed by extensive rehabilitation with joint positioning and splinting.
Authorities believe the catastrophic fire ignited when champagne bottles adorned with sparklers contacted soundproofing foam on the basement ceiling. Lausanne University Hospital currently treats seven patients from the incident, many suffering from both extensive surface burns and deep tissue damage.
