Analysis of unusual movement in 164 cases of brain death organ donors / 中华器官移植杂志

ABSTRACT

Objective By analyzing unusual movements of brain death organ donors before organ donation,to avoid misunderstanding and ensure the implementation of organ donation successfully.Methods Relevant clinical data of potential brain death organ donors admitted to the First Affiliated Hospital of Sun yat-sen University were prospectively collected between January 2016 and December 2017.The related parameters of neurological examination,neuroimaging examination and laboratory examination after brain death determination were dynamically recorded.The occurrence of limb,head and respiratory-like movement after brain death was defined as unusual movements,and the factors associated with unusual movements were screened by univariate and multivariate analysis.Results According to the inclusion criteria,164 patients were enrolled into this study.Twenty-two (13.4％) had unusual movements and duration was less than 72 h.Among them,21 (12.8％) had limbs unusual movements,6 (3.7％) had respiratory-like movement,5 (3％) owned both,and 4 (2.4％) had head rotation accompanied with limbs unusual movements.Univariate and multivariate analysis showed that axillary temperature ≤36 ℃,serum sodium ≤125 mmol/L,primary brain stem injury,spontaneous respiratory arrest time ≤72 h and age ≤ 18 years were associated with unusual movements.Conclusion During the clinical practice of brain death determination in China,the incidence of unusual movements is relatively low,and related to some factors,but it is extremely easy to cause misunderstanding.Correct cognition and interpretation are contributed to the successful implementation of organ donation.
