Clinical Analysis of the Difficulty Cerebrospinal Fluid Drainage on Spinal-epidural Anesthesia
Abstract：Objective:To analyze the causes and type of difficulty cerebrospinal fluid drainage on spinal-epidural anesthesia.Method:Retrospectively analysis of clinical cases of spinal-epidural anesthesia and ASAⅠ-Ⅲand the surgeries lower abdomen from January 2013 to November 2013,overweight,spinal deformity,height was too high and too low were excluded.The patients taken lateral position,epidural puncture with Touhy 16G needle and low resistance syringe between L3-4-5.3 times failure used other methods.Result:3560 cases were collected,1698 cases of obstetric,gynecological was 1185 cases,346 cases of general surgery,urology was 331 cases;2 epidural puncture methods were used,included perpendicularity epidural cavity puncture by center approach(Z),the“Bcs”acute angle epidural cavity puncture by lateral approach(B).3915 cases were succeed in first try and 355 cases were succeed by B when Z failure in these.The hardly drainage of cerebrospinal fluid can be divided into the completely no drainage(typeⅠ),inadequate drainage(typeⅡ).TypeⅠwas 2%,typeⅡwas 3%by“B”.TypeⅠwas 12%,typeⅡwas 11%by“Z”,there were statistic significance(P<0.05).Conclusion:The rate of hardly drainage of cerebrospinal fluid of the“Bcs”acute angle epidural cavity puncture by lateral approach is lower than that of perpendicularity epidural cavity puncture by center approach.
