Effects of comprehensive temperature preserving nursing on the levels of lactic acid in lung transplantation patients

Abstract

Objective To explore the effects of comprehensive temperature preserving nursing on the body temperature and the levels of lactic acid in lung transplantation patients. Methods Totally 46 patients underwent lung transplantation were randomly divided into experimental group and control group, with 23 patients in each group. Comprehensive insulation nursing measures were implemented in the experimental group, and conventional insulation measures were used in the control group. The rectal temperature and arterial blood lactic acid values of the two groups were recorded and compared before anesthesia (T0), after chest opening but before pulmonary artery occlusion (T1), after pulmonary artery occlusion (T2), during new lung transplantation (T3), after pulmonary artery opening (T4) and after surgery (T5). Results There was no statistically significant difference in rectal temperature and blood lactic acid between the two groups before anesthesia (t=1.53, 0.61, P>0.05). The rectal temperature of the experimental group were (36.55±0.14), (36.42±0.160), (36.33±0.13), (36.15±0.11), (36.45±0.10) ℃, which was higher than that of the control group (35.69±0.17, 35.52±0.19, 34.61±0.17, 34.47±0.13, 34.79±0.18) (F=3.24, P 0.05). The lactate levels of experimental group at T2 and T3 was higher than that before anesthesia (F=1.33, 1.16, P 0.05).In the control group, the rectal temperature during each operation period was lower than that before anesthesia (F=1.17-2.51, P<0.01), and the lactic acid level was higher than that before anesthesia (F=0.51-2.25, P<0.01). Conclusion Comprehensive heat preservation nursing measures can maintain the relative stability of body temperature during lung transplantation, which is conducive to tissue perfusion and oxygenation.
