BACKGROUND AND OBJECTIVES Peripheral nerve and spinal cord stimulation techniques have been used for many years. However, electrical stimulation methods rarely have been used to confirm epidural catheter placement. This study examines the practicality of this technique to confirm epidural catheter placement in obstetric patients. METHODS Thirty-nine obstetric patients in labor were studied. An electrocardiography (ECG) adapter (Arrow-Johans) was attached to the proximal end of the epidural… Expand
Confirmation of Direct Epidural Catheter Placement Using Nerve Stimulation in Pediatric Anesthesia
TLDR
The Tsui test did not offer any added advantage when used in the setting of directly placed epidural catheters in the authors' institution over “blind” methods already used to confirm catheter position when using cutaneous landmarks and test dosing. Expand
Determining epidural catheter location using nerve stimulation with radiological confirmation.
TLDR
The benefits and problems of using the nerve stimulation test to confirm epidural catheter placement are described and supporting evidence for these observations using radiological imaging is provided. Expand
Determining Epidural Catheter Location Using Nerve Stimulation With Radiological Confirmation
Background and Objectives The use of epidural stimulation to confirm epidural catheter placement has been shown. This case report describes the benefits and problems of using the epidural stimulationExpand
Detection of subdural placement of epidural catheter using nerve stimulation
TLDR
This new electrical test helps to detect subdural placement objectively and is recommended for use in patients undergoing general anesthesia and regional technique selection. Expand
Determination of thoracic epidural catheter placement: electrical epidural stimulation (Tsui test) is simple, effective, and under-utilized
TLDR
The study demonstrated that the EEST is a sensitive and effective test for confirming the correct position of a thoracic epidural catheter, which relates to its ability to provide adequate postoperative epidural analgesia. Expand
Epidural electrical stimulation test versus local anesthetic test dose for thoracic epidural catheter placement: a prospective observational study
TLDR
The EEST has a higher sensitivity than the LA test dose to predict adequate epidural analgesia following abdominal surgery, however, both tests have a comparable positive predictive value. Expand
An Evaluation of the Epidural Catheter Position by Epidural Nerve Stimulation in Conjunction with Continuous Epidural Analgesia in Adult Surgical Patients
TLDR
The role of the repeated use of the epidural stimulation test for quality assurance in patients undergoing postoperative continuous epidural analgesia remains undetermined. Expand
Innovative approaches to neuraxial blockade in children: the introduction of epidural nerve root stimulation and ultrasound guidance for epidural catheter placement.
  • B. Tsui
  • Medicine
  • Pain research & management
  • 2006
TLDR
Novel approaches include electrical epidural stimulation for physiological confirmation and segmental localization of epidural catheters, and ultrasound guidance for assessing related neuroanatomy and real-time observation of the needle puncture and, potentially, catheter advancement. Expand
Electrical Stimulation of the Epidural Space Using a Catheter With a Removable Stylet
TLDR
It is concluded that the TheraCath, because of the removable stylet, provides effective electrostimulation of the epidural space, and further studies are required before implementing its routine use in clinical settings. Expand
Detection of subarachnoid and intravascular epidural catheter placement
TLDR
The new test provides objective information in managing epidural catheters when their position is uncertain and confirms subarachnoid catheter placement during attempts at continuous spinal anaesthesia even though CSF could not be aspirated. Expand

Confirmation of epidural catheter placement using nerve stimulation
TLDR
This study establishes the reliability of low current electrical epidural stimulation to confirm epidural catheter placement as a simple, objective and reliable technique for confirmation of epiduralCatheter placement. Expand
High Spinal Anesthesia After Epidural Test Dose Administration in Five Obstetric Patients
TLDR
While this test dose appears to be a sensitive indicator of an unexpected subarachnoid catheter, the resulting excessive spinal blocks in these laboring patients raise the question of its safety. Expand
Histological reaction to percutaneous epidural neurostimulation: initial and long-term results.
TLDR
Long-term results, which only show dense fibrous encapsulation of the cables and the receiver, substantiate clinical belief regarding the "histological safety" of this electronic modality. Expand
Treatment of chronic pain by epidural spinal cord stimulation: a 10-year experience.
TLDR
Epidural spinal cord stimulation by means of chronically implanted electrodes was carried out on 121 patients with pain of varied benign organic etiology, and it has proven to be an effective and safe means of controlling pain on a long-term basis in selected groups of patients. Expand
Spinal cord stimulation for chronic, intractable pain: experience over two decades.
TLDR
At 7-year mean follow-up, 52% of the 171 patients who received permanent implants reported at least 50% continued pain relief, and a majority had maintained improvements in activities of daily living and analgesic use. Expand
Stimulation of the spinal neuraxis by biocompatible electrical current in the human.

TLDR
A 5-year retrospective study shows that stimulation of the neuraxis by biocompatible on-demand electrical energy systems is an effective alternative in the management of chronic organic regional pain syndromes and holds promise as a management modality for highly selected human patients with chronic pain syndrome.

The epidural test dose in obstetrics: is it necessary?
TLDR
Until a controlled study is performed, test doses should be done for continuous epidural anaesthesia with the understanding that they are neither 100 per cent sensitive nor specific in preventing complications. Expand

Safety Steps for Epidural Injection of Local Anesthetics: Review of the Literature and Recommendations
TLDR
Despite years of use, controversy still surrounds the appropriate steps to ensure the safe initiation of epidural anesthesia, including unintentional subdural, subarachnoid, and IV drug injection. Expand
Electrical stimulation of the ventral and dorsal columns of the spinal cord for relief of chronic intractable pain: preliminary report.
TLDR
Results in the patients with both implants tend to predict much better results with the possibility that ventral column stimulation alone is sufficient, and percutaneous on-surface spinal cord stimulation is advocated as an accurate screening method before implantation. Expand
