摘要
目的探讨亚低温治疗仪预防心脏手术术中患者低体温的临床应用价值。方法择期不停跳冠状动脉搭桥术患者40例,随机分为观察组(A组)、对照组(B组)2组,每组20例。术中持续监测肛温。A组在手术床铺上循环水毯,术中用亚低温治疗仪持续保温;B组则不放置。将2组间体温的变化进行比较。结果A组患者术中低温发生率为5%,约于诱导后80min出现最低温(35.9±0.6)℃,之后体温缓慢上升,至术毕体温均在36.5℃以上。B组低温发生率为96%,诱导后150min时体温下降最为明显,为(34.5±0.6)℃,术毕低温为发生率76%;与A组比较差异有统计学意义(P<0.01)。结论心脏手术中使用亚低温治疗仪进行保温治疗,可以有效预防术中低体温的发生。
Objective To evaluate the clinical application of sub-hypothermia for preventing intraoperative hypothermia during general endotracheal anesthesia. Methods 40 cases under-went off-pump coronary artery bypass graft（OPCABG） were randomly divided into two groups ： observation group （ group A, n = 20） and controlled group （ group B, n = 20）. The rectal temperature （RT） was monitored during surgery. Subhypothermia treatment was used for incubation in group A, but not in group B. Comparing the changes of RT in the two groups. Results During anesthesia and surgery,the incidence of hypothermia in group A was 5% ,the RT decreased mostly 80 minutes later（35.9± O. 6） ℃, but the RT slowly raised to above 36.5 ℃ at the end of operation. The de- crease was greater in group B ,the incidence of hypothermia was 96%. The lowest decrease occurred at 150 min after induction of aneasthesia,the temperature fell to （34.5 ± O. 6） ℃. At the end of operation, the incidence of hypothermia in group B was 76%, There were significant differences between two groups（P 〈 O. O1 ）. Conclusions The subhypothermia can prevent intraoperative hypothermia during OPCABG.
