Abstract:
Objective To observe the effect of hypothermia in reperfusion stage on prognosis during adult liver transplantation.Methods Data of 107 patients (62 males, 45 females, aged 25～65 years, ASA physical status Ⅲ or Ⅳ) underwent adult liver transplantation from January 2015 to December 2016 in our hospital were retrospectively analyzed.The temperature at the time of anesthesia induction (T0), skin incision (T1), anhepatic phase immediately (T2), immediate reperfusion (T3), 5 min after reperfusion (T4), abdomen-closing (T5) and the end of surgery (T6) were recorded to observe the trend of overall temperature change.Patients were devided into normal temperature group (core temperature was≥35℃ or ＜35℃ but the duration was less than 5 min in reperfusion period) and hypothemia group (core body temperature was ＜35℃ and the duration was>5 min) to compare difference between the two groups of perioperative blood loss, urine volume, postoperative extubation time, ICU staying time and hospitalization time.The influence of hypothermia during the new liver phase (T4-T6) on prognosis and correlation between duration of hypothermia and blood loss, urine volume, postoperative extubation time, ICU staying time and hospitalization time were analyzed.Results This study found that during the perioperative adult liver transplantation, the body temperature showed a decreasing trend first (T0-T4) and then an increasing one (T4-T6).The body temperature droped to the lowest at T4, which was lower than the normal body temperarure.Compared with T0, the temperature decreased obviously at T2-T5 (P＜0.05);Compared to normal temperature group, the amount of bleeding was more and the extubation time was longer in hypothermia group (P＜0.05), and there was no significant difference in urine volume, ICU staying time and hospitalization time between the two groups.There were positive correlations between the time of hypothermia and bleeding, extubation time, ICU staying time and negative correlations with urine output, while no obvious relations with postoperative hospital staying time.Conclusion During the perioperative liver transplantation, hypothermia increased the blood loss and postoperative extubation time.The longer the hypothermia time is, the poorer the prognosis is.
