ABSTRACT
Objective To retrospectively analyze unplanned secondary surgical operations in neurosurgery. Methods The incidence, causes and time interval from the first operation of unplanned secondary operations were systematically reviewed, and the length of stay, hospitalization expenses and conditions of prognosis of the patients were compared with those who did not suffered from unplanned secondary operations.Results In this study,339 unplanned secondary operations were confirmed from 2012 to 2016 in neurosurgery and the incidence of unplanned secondary operations was 0.65%. 80.24% of the unplanned secondary operations were incurred by postoperative bleeding,which was proved to be higher than other causes. Conclusions Unplanned secondary operations had caused more economic burdens, thus deserving close attentions. Reducing perioperative bleeding and implementing hierarchical operation management would be key to preventing and decreasing unplanned secondary operations.
ABSTRACT
Objective To analyze the alterative characteristics of the extravascular lung water (EVLW ) in the patients with septic shock and clarify its value on the prognosis of these patients.Methods By the methods of retrospective analysis,according to the ultimate survival,21 patients with septic shock were divided into survivor group (10 cases) and non-survivor group (11 cases).The clinical features of the patients were observed and hemodynamic monitoring was made with PiCCO monitor.The EVLW was measured and the relationship between the EVLW and the prognosis of patients was analyzed.Results On the first,second and third day,EVLW was (12.7 ±1.8),(11.3 ±1.3),(10.1 ±1.3) ml/kg in survivor group,and (14.4 ± 1.0),(14.6 ± 1.4),(14.6 ±1.3) ml/kg in non-survivor group respectively,and there were statistical differences between two groups (P 0.05).Conclusions The EVLW in the patients with septic shock increases significantly.The dynamic changes of the EVLW may be one of the factors for predicting the prognosis of patients with septic shock.
