With the appearance of microcatheters in 1990 there was a resurgence of interest in continuous spinal anesthesia (CSA) [1]
Three years after its initial use in Germany, it arrived in Brazil and one year after, the first article was published with this new catheter for CSA in 40 patients with orthopedic lower limb surgery, suggesting CSA with the catheter outside the needle shows minor insertion problems and a low incidence of hypotension [5]
Paresthesia was observed in only 27 patients
Summary
With the appearance of microcatheters (calibers 28 to 32G) in 1990 there was a resurgence of interest in continuous spinal anesthesia (CSA) [1]. Caliber catheter, 73 cm long, is mounted outside a spinal anesthesia needle caliber 27G and 29G, with Quincke point. It has terminal opening and only one side hole 0.5 cm from the tip, requiring only an inch of your length is introduced into the subarachnoid space. Database analysis in general cost less and require less time as compared to large randomized controlled trials. This retrospective study with a catheter outside the cutting-tip needle for continuous spinal anesthesia for femur and hip surgery in elderly patients from 1998 to 2015, with the aim of determine possible advantages and disadvantages of this technique
