Effect of Intravenous Sodium Pentobarbital on Pain and Sensory Abnormalities in Patients with Chronic Non-Cancer Pain: Narrative Literature Review, Research Study, and Illustrative Case Reports.
Introduction: Sodium pentobarbital (SP), a short- to intermediate-acting barbiturate, has limited information in the existing literature. The objectives of this study are to describe (a) the effect of intravenous (IV) SP infusion on pain and sensory abnormalities, and (b) its utility in the diagnosis and management of patients with chronic pain.
Methods: A narrative review of barbiturate applications for chronic pain was followed by a pragmatic study of 176 consecutive patients admitted to an inpatient pain unit (2004-2009). We collected demographic information upon admission, diagnoses retrieved from chart review, and pain ratings and sensory abnormalities at baseline and after blinded infusion of normal saline (NS) followed by SP.
Results: The study group consisted of 83 men and 93 women (mean age 41 ± 11 years); the mean NS dose was 7.8 ± 2.3 (range 2-10 ml), the SP dose was 223.8 ± 88 mg (range 40-420), and the numeric rating scale (NRS) baseline pain score was 6.0 ± 2. The mean reduction in NRS reached both statistical and clinical significance in 150 responders to either NS/SP or SP only. Collectively, we found (a) an extremely high rate of response to IV SP irrespective of the underlying pathology, (b) greater response for pain than for sensory abnormalities (sensory gains or deficits), (c) greater response for sensory gain than for sensory deficit, and (d) greater response for allodynia than for pinprick hyperalgesia. Illustrative case reports are also presented.
Discussion: IV SP infusion is a diagnostic tool that assists in elucidating pain generators and the nature of sensory abnormalities (central vs. peripheral), with effects similar to those of IV sodium amytal. The test cannot be viewed as a tell-all diagnostic modality and must be used in conjunction with clinical judgment, investigations, and psychological reports.
期刊介绍：
Pain and Therapy is an international, open access, peer-reviewed, rapid publication journal dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of pain therapies and pain-related devices. Studies relating to diagnosis, pharmacoeconomics, public health, quality of life, and patient care, management, and education are also encouraged.
Areas of focus include, but are not limited to, acute pain, cancer pain, chronic pain, headache and migraine, neuropathic pain, opioids, palliative care and pain ethics, peri- and post-operative pain as well as rheumatic pain and fibromyalgia.
The journal is of interest to a broad audience of pharmaceutical and healthcare professionals and publishes original research, reviews, case reports, trial protocols, short communications such as commentaries and editorials, and letters. The journal is read by a global audience and receives submissions from around the world. Pain and Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of all scientifically and ethically sound research.
