We present here a technique to mitigate the complication of multiple needle entries into the thecal sac when attempting to place an intrathecal catheter into the thecal sac. Our technique of injecting radio-opaque contrast material after entering the epidural space and before entering the thecal sac allows for visualization of the thecal sac within the spinal canal, thus obviating the technique of "fell and pop" to enter the sac. In our hands, this technique has improved outcomes for our patients and has decreased the incidence of post dural puncture headache, neural trauma and technical failures.

Electrical stimulation of the digestive organs may become a valuable alternative to pharmaceutical and surgical approaches to the treatment of gastrointestinal motor dysfunctions. For more than 40 years, encouraging results with electrical stimulation to activate motility in gastrointestinal organs have been published. ⋯ In addition, animal studies have investigated the different stimulation systems and methods to activate or inhibit transit in the small and large intestines. This article presents a review of the published literature on electrical stimulation of the stomach and intestines.

Studies performed to date have shown that electrical stimulation of the stomach and intestines can create or modulate motility functions in the gastrointestinal (GI) tract. Therefore, electrical stimulation of GI organs may become a valuable alternative to medication and surgical approaches in the treatment of GI motor dysfunctions. ⋯ Presently, it is known that electrical stimulation of GI organs triggers complex reactions comprising excitatory and inhibitory responses of the excitable components performing or controlling motility in the GI tract. I present here a review of what is known of the mechanisms of GI organ stimulation.
