Dorsal Root Ganglion Stimulation for the Management of Phantom Bladder Pain: A Case Report.

Phantom bladder pain, a rare condition following cystectomy, can pose a challenge to pain management providers. We present the case of a 43-year-old male who developed severe phantom bladder pain post-cystectomy. Despite multiple treatments, his symptoms persisted, significantly affecting his quality of life. Dorsal root ganglion stimulation (DRGS) was attempted after conventional therapies failed. The DRGS trial provided significant relief, leading to permanent implantation and a 90% reduction in pain. This case highlights DRGS as a potential treatment for phantom bladder pain, expanding its applications beyond traditional uses. Further research is needed to elucidate its mechanisms and broader applicability.

Wireless High-Frequency Peripheral Nerve Stimulation for Chronic Refractory Knee Pain Post-total Knee Replacement.

The number of joint replacement surgeries, especially knee replacement surgeries, is rising with the rising geriatric population. Chronic unremitting knee pain post-total knee replacement surgery is a common phenomenon. Usually, the pain responds to conservative measures, including physical therapy and medical management. In some patients, the pain post-knee replacement surgery can be refractory and unremitting. In such scenarios, peripheral nerve stimulation, or neuromodulation, can be an effective option.

Dorsal Root Ganglion Stimulation Therapy for Refractory Idiopathic Pudendal Neuralgia.

Dorsal root ganglion stimulation is a relatively new treatment option for chronic pain conditions such as pudendal neuralgia, which is a chronic pain condition affecting the pudendal nerve in the pelvic region. Pudendal neuralgia is a debilitating condition that can significantly affect the patient's quality of life. In dorsal root ganglion stimulation, a small device is implanted that delivers electrical impulses to the dorsal root ganglion to modulate pain signals coming from the pudendal nerve. The procedure is considered investigational and has been investigated in case series and case reports with promising results. However, more research is needed to fully understand its safety and effectiveness. This case report highlights the potential of dorsal root ganglion stimulation as a treatment option for pudendal neuralgia and the need for further research to establish it as a standard treatment option.

Ultrasound-Guided Erector Spinae Block for Refractory Abdominal Pain Due to Acute on Chronic Pancreatitis.

Erector spinae blocks (ESBs) are a type of fascial pain block that has been safely used for various applications, including post-operative and post-trauma pain in several thoracic and abdominal surgeries. Pain related to an acute flare-up of chronic pancreatitis is usually challenging to control and impacts patient comfort and discharge planning. This case report describes an application of ESBs for the effective treatment of refractory abdominal pain associated with acute exacerbation of chronic pancreatitis. Application of ESB in the emergency room setting can potentially decrease hospital admission for this common condition and increase patient satisfaction.

A Microbiological Assay of Common Operating Room (OR) Tapes: Developing a Culture for Patient Safety.

BACKGROUND: There are no existing practices or methods to ensure cleanliness, sterility, or prevent cross-contamination when it comes to common operating room (OR) tape. The authors hypothesized that adhesive tapes used by anesthesia providers in ORs and off-site surgical areas might be colonized by microorganisms and that culturing these tape rolls would reveal significant monomicrobial and polymicrobial contamination.  Material and Methods: The primary objective of this observational cohort study was to report and compare contamination rate including polymicrobial contamination rate between tape specimens collected from storage site and specimen from the ORs, off-sites, and after use on a patient. The outcome measures were the culture reports of the adhesive tapes. The authors then designed an intervention that integrated anesthesia providers' hand hygiene and maintenance of a barrier between the OR tapes and OR surfaces. RESULTS: The authors reported gross contamination and cross-contamination among the OR off-site tapes. The contamination rates reported for tapes from OR, off-site specimens, and patient specimens were 68.2%,63.2%, and 100%, respectively. The authors again cultured adhesive tapes after the intervention and reported improved outcomes. CONCLUSIONS: The current quality improvement (QI) project identified the potential for OR tapes to serve as microbial vectors. The authors advocate environmental decontamination and anesthesia providers' hand hygiene in parallel as a part of routine anesthesia care in their practice and agree that the endotracheal tubes (ETTs) and orogastric or nasogastric tubes should be pre-packaged with single-use tape, which can be used for securing devices.

Upper Antero-Medial Thigh as an Alternative Site for Implantation of Intrathecal Pumps: A Case Series.

INTRODUCTION: Neuraxial drug delivery via intrathecal drug delivery systems (IDDS) is becoming an increasingly common mode of treating intractable cancer-related pain, chronic pain, or severe spasticity. An implanted infusion pump delivers medication into the intrathecal (subarachnoid) space via a thin catheter. These pumps are commonly placed in the anterior abdominal wall. Certain conditions may render it difficult or unsafe for an IDDS to be implanted at the traditional site; thus, alternative sites have been explored. We report on the use of the upper antero-medial thigh as a safe alternative site for this purpose. METHODS AND MATERIALS: Nine patients between 22 and 69 years of age underwent placement of an IDDS infusion pump in the upper antero-medial aspect of one thigh. In each patient, the anterior abdominal wall was precluded for implantation due to various reasons, such as extensive abdominal scar tissue from previous surgeries, placement of feeding tubes and ostomies, large ventral hernia or metastatic masses protruding from the abdomen. RESULTS: Nine patients, with ages ranging from 22 to 69 years old, had IDDS implantation in the upper thigh. The first patient experienced wound dehiscence (antero-lateral location) and after explantation, another pump was placed successfully in the opposite thigh (antero-medial location). One patient has had pump replacement due to end-of-battery life. She also needed an unrelated catheter revision. Seven patients have expired from their disease progression after living for an average of 142.7 days (range 50 days to 354 days) while two patients continue to experience relief from pain and spasticity years later (see Table 1). No neurovascular damage, infections, or other complications occurred in our series. CONCLUSION: The upper antero-medial thigh is a safe alternative to the anterior abdominal wall for implantation of an IDDS.
