Background
DECUBITUS, COMPLICATIONS
Combined spinal-epidural anesthesia (CSEA) combines the advantages and mitigates the disadvantages of single-shot spinal anesthesia and continuous epidural anesthesia, and is an essential component of neuraxial anesthesia in anesthesiology residency training. The most popular CSEA technique is the needle-through-needle technique in which the epidural needle serves as an introducer for the spinal needle. Puncture in lateral decubitus position is a common method of CSEA.The height of the operating table affects the comfort and performance of the operator [Furthermore, the vision interference induced by table height may affect residents more than experienced clinicians. It remains unclear whether this vulnerability would decrease after a period of training.The purpose of the present study was to evaluate whether the operating table height affected the success rate and incidence of complications for CSEA in lateral decubitus position performed by residents during training.
