RESUMEN
Objective To explore the speech respiratory characteristics of 7-15 years old children with spastic cerebral palsy and the differences between ordinary children and children with cerebral palsy.Methods The maximum phonation time (MPT) and maximum counting ability (MCA) of 90 ordinary children and 58 children with cerebral palsy aged 7-15 years were measured and a comparison between the 2 groups were conducted.Results (1) Age has significant effects on MPT and MCA of the ordinary children (P ＜0.05).The MPT and MCA of the ordinary children at the age of 7 ～9 years and 10 ～ 12 years are lower than the ones at the age of 13 ～ 15 years.Age has almost no effects on MPT and MCA of children with cerebral palsy(P ＞0.05) ; (2)Sex has no significant effects on MPT and MCA of ordinary children and children with cerebral palsy (P ＞0.05) ; (3) The MPT and MCA of children with cerebral palsy are significantly lower than those of ordinary children (P ＜0.05).Conclusions The MPT and MCA of ordinary children are increased with the growth of age,especially after the age of 13 years,but the children with spastic cerebral palsy do not show that kind of trend and demonstrate a state of retardation of speech respiratory function.Compared with ordinary children,the children with spastic cerebral palsy are easier to suffer from insufficient respiratory support and poor respiratory-phonatory coordination.
RESUMEN
Objective To investigate the acoustic characteristics of the voice of 3~6 years old children with hearing-impairment. Meth-ods The voice samples were collected from 148 hearing-impaired children and 122 normal children, all aged 3~6 years. The acoustic param-eters including F0, F0SD, jitter, shimmer, NNE, OQ, SQ, AQ, STF were compared. Results The F0, SQ, STF, F0SD, jitter were more in the children with hearing-impairment than in the normal children (P0.05). There was no significant difference of all the acoustic parameters among chil-dren with different ages (P>0.05), except the NNE was less in 3~4 years old children than 5~6 years old children (P0.05). Conclusion The vibration of vocal cords is instable and ir-regular, saying overquick and close intensely in hearing-impaired children. The age and sex do not influence the acoustic parameters, except NNE is less in younger children.
RESUMEN
Objective To investigate the cause and nursing of the abdominal incision dehiscence.Methods The clinical data of 18 cases of abdominal incision dehiscence after surgery were analyzed retro-spectively from January 1998 to June 2008 in our hospital.Results Abdominal wound dehiscence was caused by various factors,such as basic disease,anesthesia during operation,suture techniques and postop-erative care.Conclusions We should pay attention to the relevant factors of incision dehiscence and make the appropriate care and treatment when patients are admitted to hospital.Correction of malnutrition,strengthening the treatment of basic disease,attention to suture technique ale helpful for reducing the inci-dence of abdominal incision dehiscence.
