Comparison of Core Temperature Changes Between Pediatric Patients Lying on Regular Operating Room Linen Drapes and Water-Repellent Sheepskin Rug in Living Donor Liver Transplantation

Objectives: The aims of this study were to compare the core temperature changes between pediatric patients lying on regular operating room linen drapes and a water-repellent sheepskin rug during living donor liver transplantation (LDLT) and to evaluate the effectiveness of using a water-repellent sheepskin rug in preventing profound hypothermia due to fluid overflow from the abdominal cavity during LDLT. Patients and Methods: The operative records of pediatric patients who underwent LDLT from June 1994-September 2003 were reviewed retrospectively. The nasopharyngeal temperature (NT) changes during the LDLT procedure between patients lying on regular operating room drapes (GI) and water-repellent sheepskin rug (GII) were compared and analyzed using the Mann-Whitney U test. A P value <.05 was regarded as significant. Results: Thirty-two patients were included in GI and 56 in GII. Profound hypothermia was not observed in any recipients lying on a water-repellent sheepskin rug (GII). The NT after induction and the following 4 hours into the LT procedure were significantly higher in GII than GI. Conclusion: Pediatric patients lying on water-repellent sheepskin preserved their core temperature better in comparison to patients lying on linen drapes. The use of a water-repellent sheepskin rug seems to be effective in preventing profound hypothermia related to physical contact with abdominal fluid overflow during the LDLT.
