A RETROSPECTIVE SURVEY OF NEUROLOGICAL COMPLICATIONS OF INTRATHECAL ANESTHESIA AT 64 HOSPITALS IN GUANGXI
Description
The preliminary analysis on the usage of intrathecal anesthesia and the incidence and rehabilitation rates of neurological complications after intrathecal anesthesia in 64 hospitals in Guangxi. To accumulate the clinical experience of intrathecal anesthesia and epidemiology data of neurological complications after intrathecal anesthesia. From 2008 to 2012, there is the most commonly used in CSEA, but also showed an increasing trend. Followed by EA, EA showed a downward trend. SA is used the least. The incidence of neurological complications after intrathecal anesthesia was 0.0408%, the incidence of neurological complications of EA, CSEA and SA were 0.0201%, 0.0552%, 0.049%, respectively (P﹤0.05). The incidence of three anesthesia neurological complication were compared, the difference was statistically significant (P = 0.000), the incidence of neurological complication after EA was the least, CESA was the most. There are statistically significant difference between the incidence of neurological complication of the two kinds grade hospital (P﹤0.05), the incidence of neurological complications in large and comprehensive hospital was more than that of non-large and comprehensive hospital , the odds ratio(OR) was 0.589 (95% CI:0.442~ 0.786 ). The incidence of TNS was the most, 0.0340%, followed by radicular damage (0.005%), the other three types of complications were relatively rare, 0.0008%, 0.0008%, 0.0002%, respectively. (P﹤0.05)The total cure rate of neurological complications was 89.8%, the cute rate of three kinds of anesthesia were 87.80%, 90.26%, 90.0% ,respectively, the difference was not statistically significant (P﹥0.05). All TNS patients were fully recovered (100%)，48% in radicular damage, 25% in cauda equina syndrome, the other two types complication of patients developed permanent damage. The total incidence of permanent neurological complication was 0.0042%. The incidence of permanent complications of EA ,CSEA and SA were 0.0034% ,0.0047% and 0.0049%（P﹥0.05）.

After the approval of anesthesia quality control center in Guangxi, a retrospective study analysis was carried out from January 1, 2008 to December 31, 2012, to aim at neurological complications of intrathecal anesthesia in 64 hospitals. Self-designed questionnaire of neurological complications of intrathecal anesthesia. From October 2012, informed directors of anesthesiology department at all levels of the hospital's by both letter and phone message on behalf of anesthesia quality control center in Guangxi Zhuang Autonomous Region to download survey forms on neurological complications of intrathecal anesthesia by internet and finish form 1 and form 2, included age, sex, date of operation, preoperative diagnosis, past medical history, anesthesia techniques, time of anesthesia and operative, surgical technique , anesthesia puncture site and parethesia, usage of postoperative analgesic and anesthetic ,record the course of neurological complications, cure and neurological sequelae, and so on .
