OBJECTIVES: To describe current UK clinical practice around the use of intrathecal diamorphine as analgesia for major elective laparoscopic colorectal surgery. DESIGN: Online self-administered survey. SETTING: Acute public hospitals in the UK (National Health Service - NHS) . PARTICIPANTS: Consultant anaesthetists involved in colorectal surgery lists. MAIN OUTCOME MEASURES: Rate of intrathecal opioids used by anaesthetists for elective laparoscopic colorectal procedures; minimum, most common and maximum doses of intrathecal diamorphine used, timing of administration of intrathecal injection, and relationship between the number of patients anaesthetised for laparoscopic colorectal resections per month by each anaesthetist, and the doses of intrathecal diamorphine they administer...

In 2021, the manufacturer of diamorphine reported a possible impending shortage for Switzerland and Germany. This led us to investigate this controlled medicine's manufacture, market, and regulatory constraints. Based on our analysis of legal texts and gray literature in the form of reports and documents, we propose recommendations to prevent and address diamorphine shortages in Switzerland. Diamorphine, also known as pharmaceutical "heroin," is used medically to treat persons with severe opioid use disorder in a handful of countries...

BACKGROUND: Children and young people are usually given liquid morphine by mouth for breakthrough pain, which can take thirty minutes to work. A faster-acting, quickly absorbed, needle-free pain medicine, that is easy to administer is needed such as transmucosal (sublingual, buccal, intranasal) diamorphine. Research evidence relating to the administration of medication for breakthrough pain in children and young people is limited. This study aims to describe the experiences and preferences of parents and/or children and young people regarding the route of administration of diamorphine, barriers and facilitators comparative to oral morphine, and participation in a randomised controlled trial...

BACKGROUND: The purpose of this study was to evaluate the efficacy of intrathecal morphine (ITM) in combination with bupivacaine as pre-emptive analgesia in patients undergoing posterior lumbar fusion surgery. This is in comparison with traditional opioid analgesics such as intravenous (IV) morphine. METHODS: Two groups were identified retrospectively. The first (ITM group) included patients who had general anaesthesia (GA) with low-dose spinal anaesthesia prior to induction using 1-4 mls of 0...

The higher skin surface area to body weight ratio in children and the prematurity of skin in neonates may lead to higher chemical exposure as compared to adults. The objectives of this study were: (i) to provide a comprehensive review of the age-dependent anatomical and physiological changes in pediatric skin, and (ii) to construct and evaluate an age-dependent pediatric dermal absorption model. A comprehensive review was conducted to gather data quantifying the differences in the anatomy and physiology of child and adult skin...

OBJECTIVES: No randomised controlled trials have been conducted for breakthrough pain in paediatric palliative care and there are currently no standardised outcome measures. The DIPPER study aims to establish the feasibility of conducting a prospective randomised controlled trial comparing oral and transmucosal administration of opioids for breakthrough pain. The aim of the current study was to achieve consensus on design aspects for a small-scale prospective study to inform a future randomised controlled trial of oral morphine, the current first-line treatment, versus transmucosal diamorphine...

Diamorphine is a strong opioid licensed in the UK for many uses, including moderate and severe pain. In the early 2000s, its use in palliative medicine was widespread before a supply disruption led to preferential use of alternative, cheaper opioids. Though these supply issues were resolved, the use of diamorphine in palliative medicine has remained reduced, particularly with another UK supply disruption in 2021. Following anecdotal reports of good results from diamorphine use in younger patients, this piece discusses two cases of young patients with metastatic cancers suffering significant pain and psychological distress...

Topical opioid formulations offer a potential solution to manage pain and decrease the use of systemic opioids. Synthesis of use and efficacy of topical opioids in dermatological conditions has not been well characterized. We conducted a systematic search of the PubMed, Embase, and Cochrane databases from 1980 to February 2021. This study analyzed data from 14 articles and 263 patients on the use of topical opioids for pain related to chronic ulcers, burns, oral lichen planus, photodynamic therapy, and split-thickness skin grafts...

To achieve global hepatitis C virus (HCV) eradication, barriers prohibiting treatment access need to be overcome. We established a strategy to initiate antiviral therapy in patients with severe, refractory heroin addiction. All patients achieved sustained virological response. Outreach programs of hepatologists might be a reasonable way to overcome barriers to HCV treatment.

Intrathecal morphine in combination with fentanyl is an effective and safe alternative to diamorphine for Caesarean delivery analgesia. Evidence suggests minimal differences in clinical efficacy and side-effects between intrathecal morphine and diamorphine. Recommended intrathecal morphine doses for Caesarean delivery analgesia are 100-150 ug.

PURPOSE: We aimed to compare the beneficial and harmful effects of opioids used as adjuncts to local anesthetics in patients undergoing cesarean section under spinal anesthesia. METHODS: We searched electronic databases and ClinicalTrials.gov from their inception until March, 2021 without language restrictions. The primary outcome was the complete analgesia duration (Time to VAS > 0). Data were synthesized using the Bayesian random-effects model...

Britain was the first country in the world to prescribe diamorphine (pharmaceutical-grade heroin) to heroin users as a treatment for opioid dependency. Known and admired internationally as the British System, Britain has a somewhat more ambivalent relationship to its own invention. Where patients were once prescribed diamorphine and other injectable opioids on an unsupervised basis, new patients are no longer initiated in this way and those existing 'old system' patients are under threat. Carrying out ethnographic research at an advocacy service for people who use drugs, I explore this threat as an onto-epistemological concern and the advocates' work to sustain these 'old' ways of knowing and being with diamorphine as a collective matter of care and action...

PURPOSE OF REVIEW: This article aims to provide an overview of standard and adjunctive treatment options in opioid dependence in consideration of therapy-refractory courses. The relevance of oral opioid substitution treatment (OST) and measures of harm reduction as well as heroin-assisted therapies are discussed alongside non-pharmacological approaches. RECENT FINDINGS: Currently, recommendation can be given for OST with methadone, buprenorphine, slow-release oral morphine (SROM), and levomethadone...

BACKGROUND: Oral morphine is frequently used for breakthrough pain but the oral route is not always available and absorption is slow. Transmucosal diamorphine is administered by buccal, sublingual or intranasal routes, and rapidly absorbed. AIM: To explore the perspectives of healthcare professionals in the UK caring for children with life-limiting conditions concerning the assessment and management of breakthrough pain; prescribing and administration of transmucosal diamorphine compared with oral morphine; and the feasibility of a comparative clinical trial...

BACKGROUND: Research on quality of life (QoL) of chronically ill patients provides an opportunity to evaluate the efficacy of long-term treatments. Although it is established that opioid replacement therapy is an effective treatment for opioid-dependent patients, there is little knowledge about physical and psychological functioning of QoL for different treatment options. OBJECTIVES: Altogether, 248 opioid-dependent patients receiving substitution treatment with either methadone/levomethadone (n = 126), diamorphine (n = 85), or buprenorphine (n = 37) were recruited in 6 German therapy centers...

BACKGROUND: Mechanical ventilation is a potentially painful and discomforting intervention that is widely used in neonatal intensive care. Newborn infants demonstrate increased sensitivity to pain, which may affect clinical and neurodevelopmental outcomes. The use of drugs that reduce pain might be important in improving survival and neurodevelopmental outcomes. OBJECTIVES: To determine the benefits and harms of opioid analgesics for neonates (term or preterm) receiving mechanical ventilation compared to placebo or no drug, other opioids, or other analgesics or sedatives...

BACKGROUND: Thoracic epidural analgesia (TEA) has been regarded as the standard of care after oesophagectomy for pain control, but has several side-effects. Multimodal (intrathecal diamorphine, paravertebral and rectus sheath catheters) analgesia (MA) may facilitate postoperative mobilization by reducing hypotensive episodes and the need for vasopressors, but uncertainty exists about whether it provides comparable analgesia. This study aimed to determine whether MA provides comparable analgesia to TEA following transthoracic oesophagectomy...

If an accidental dural puncture occurs, one option is to insert a catheter and use it as an intrathecal catheter. This avoids the need for a further injection and can rapidly provide labour analgesia and anaesthesia for caesarean section. However, there are no recommendations for managing intrathecal catheters and, therefore, significant variation in clinical practice exists. Mismanagement of the intrathecal catheter can lead to increased motor block, high spinal anaesthesia, drug error, hypotension and fetal bradycardia...

Caesarean section is associated with moderate-to-severe postoperative pain, which can influence postoperative recovery and patient satisfaction as well as breastfeeding success and mother-child bonding. The aim of this systematic review was to update the available literature and develop recommendations for optimal pain management after elective caesarean section under neuraxial anaesthesia. A systematic review utilising procedure-specific postoperative pain management (PROSPECT) methodology was undertaken. Randomised controlled trials published in the English language between 1 May 2014 and 22 October 2020 evaluating the effects of analgesic, anaesthetic and surgical interventions were retrieved from MEDLINE, Embase and Cochrane databases...
