Objective To evaluate the clinical and radiological factors which affecting the recovery duration of C5 palsy after cervical decompression surgery.Methods The datas of 710 patients with degenerative cervical spine surgery in departement of spine surgery of orthopaedics of general hospital of Shenyang military region were retrospectively analyzed.The demographics,radiology,clinical information were recorded to analyze the relationship with the recovery duration of postoperative C5 palsy.Results C5 nerve root palsy occurred in 36 cases,of which 33 cases completely recovered within 2 years after surgery(18 cases recovered within postoperative 6 months),3 cases did not completely recovered during the following period.Factors related to longer recovery(over 6 months) included postoperative limbs muscles strength ≤2(P＜0.01),presence of multi-segment paresis involving more than the C5 root(P =0.002),loss of somatic sensation with pain(P =0.008),and the degree of posterior spinal cord shifting (P =0.040).Furthermore,multivariate analysis revealed that postoperative limbs muscles strength ≤2(P =0.010) had a significant effect on a recovery duration beyond 6 months.Conclusion The postoperative limbs muscles strength ≤2,the presence of multi-segment paresis involving more than the C5 root,the loss of somatic sensation with pain,and the degree of posterior spinal cord shifting are main factors which significantly influence the duration of recovery from postoperative C5 nerve root palsy.
Résumé
Objective:TThe aim of this study was to observe the changes of the volume and distribution of body fluid after abdominal surgery,and further to explore its characteristics and influence factors.Methods:Sixtyone patients were included between March and June in 2016.The volume of intracellular water (ICW),extracellular water (ECW) and total body water (TBW) was estimated by InbodyS 10 on preoperative day 1 (PreD 1) and postoperative day (POD) 1,3,5 and 7.Furthermore,the patients were grouped according to the age,sex,type of operation,operation time and the daily liquid input,and the influence factors of postoperative fluid volume were analyzed in each subgroup.Results:Comparing to that of PreD1,the ICW,ECW,and TBW,mainly ECW,were increased significantly on POD1 (P＜ 0.05),and the level of postoperative fluid volume was decreased to that of PreD1 between POD3 and POD7.It showed that there was difference in the net increasing of body fluid on POD1 between different type of the patients.Obviously,the net increasing of fluid volume in woman on POD 1 was more than that in man.The net increasing of fluid volume on POD1 was correlated with the operation time and net liquid input.Conclusion:The fluid retention was found in the early stage of postoperative patients,and mainly exists in ECW.The main influence factors resulting postoperative fluid retention were prolonged operation time and increased net fluid input.
