Randomized Controlled Trial[Paresthesia in various spinal anesthesia techniques for cesarean section].
To determine the incidence of paresthesia with different spinal puncture techniques using a 27-gauge Whitacre needle. ⋯ Combined epidural-subarachnoid puncture leads to a higher incidence of paresthesia in comparison with simple spinal puncture, probably because the lumbar puncture is performed on a dural sac that has been previously deformed due to the "tent effect" caused by the epidural needle. Fewer cases of paresthesia occur when the subarachnoid puncture is slow and steady and the introducer needle is withdrawn millimeters before it reaches the dural sac.

Randomized Controlled Trial Comparative Study[Cellular immune response to 3 anesthetic techniques for simple abdominal hysterectomy].
The effect of surgery and anesthesia on the immune response may have a significant effect on perioperative tumor surveillance. The aim of this study was to characterize the cellular immune response of patients undergoing simple abdominal hysterectomy under 3 types of anesthesia. ⋯ Combined general-epidural anesthesia seems to lower the counts of natural killer cells that are involved in tumor surveillance and destruction.
