Abstract
- Background Rapid cooling at procurement after cross-clamping has been the cornerstone of organ preservation. NanoICE is a new form of ice that has emerged in the food industry and is providing more efficient cooling and preservation than regular ice. We hypothesize that the use of NanoICE will accelerate the cooling process of the allograft and will be able to maintain a steady low temperature without causing any significant histologic damage. Methods In this randomized pilot study, 14 pigs were used to study the liver core/surface cooling in a non-survival organ procurement operation. Animals were randomly assigned to 1 of 2 groups, each arm involving 7 pigs: (1) crushed-iced normal saline cooling method (control group) and (2) NanoICE cooling method (study group). Surface and core temperatures were measured with temperature probes, and liver biopsies were obtained before cross-clamping and 15 hours after preservation to assess for any evidence and degree of freezing injury. Results NanoICE was able to reduce and sustain lower core temperatures at 30 minutes, 60 minutes, and 15 hours, compared with crushed ice. The degree of histologic damage (reflecting cold injury) at 15 hours after flushing was not significantly different between the 2 methods. Conclusions NanoICE cools the deeper liver parenchyma more quickly and sustains a cooler temperature than regular crushed ice without causing significantly histologic damage. Future research should focus on whether the effect of NanoICE has any impact on graft function and survival.
