Case ReportsOral ketamine for sickle cell crisis pain refractory to opioids.
There is literature demonstrating that the N-methyl-d-aspartate (NMDA) receptor antagonist ketamine has analgesic properties that can be used as an adjuvant to opiates for pain relief in multiple various conditions and pain states. However, there is a lack of published information on ketamine used in persons with sickle cell disease in acute pain crises. The Virginia Commonwealth University Palliative Care team was consulted on a 38-year-old African American female with sickle cell thalassemia in severe acute pain crisis overlying chronic pain related to her disease. ⋯ The patient responded well to an intravenous test dose of ketamine and was subsequently placed on an oral regimen of ketamine in addition to opiates. In the 24-hour period following ketamine initiation, the patient's pain was able to be controlled on decreased amounts of opiates. She was eventually transitioned to an oral opiate and ketamine regimen, which allowed her to be discharged home with pain levels close to her baseline and the ability to function and perform all activities of daily living.

Review Comparative StudyUsing haloperidol as an antiemetic in palliative care: informing practice through evidence from cancer treatment and postoperative contexts.
Nausea and vomiting are common symptoms in palliative care. Haloperidol is often used as an antiemetic in this context, although direct evidence supporting this practice is limited. To evaluate the efficacy and clinical use of haloperidol as an antiemetic in nonpalliative care contexts to inform practice, the authors conducted a rapid review of (i) published evidence to supplement existing systematic reviews, and (ii) practical aspects affecting the use of haloperidol including formulations and doses that are commonly available internationally. ⋯ In palliative care, an observational study found a complete response rate of 24% with haloperidol (one in four patients) which would be consistent with a number needed to treat (NNT) of 3 to 5 derived from PONV. There remains insufficient direct evidence to definitively support the use of haloperidol for the management of nausea and vomiting in palliative care. However, generalizing evidence from other clinical contexts may have some validity.

ReviewThe pharmacoeconomics of breakthrough cancer pain.
Breakthrough cancer pain (BTP) has a significant impact on patients' activities of daily living, family, and the society; however, the economic ramifications of BTP are largely unknown. This review aims to summarize the available pharmacoeconomics studies of BTP in the context of the availability of several formulations of rapid-onset opioids administered by various routes, which are significantly more expensive than oral opioids. A systematic literature search of PubMed and Tufts registry through August 2012 was conducted using key words including "breakthrough cancer pain" and "cost effectiveness." After exclusion of irrelevant articles, a total of six articles were included. ⋯ Only one study comparing placebo with intranasal fentanyl spray, oral transmucosal fentanyl citrate, and oral transmucosal fentanyl buccal tablet has demonstrated the cost-effectiveness of these rapid-onset opioids for the treatment of BTP. Overall, there is a lack of pharmacoeconomic studies for BTP management with rapid-onset opioids. Further study is warranted assessing the net benefit of rapid-onset opioids to oral opioids to assist decision-making by patients, clinicians, and payers.

Prescription opioid guidelines and the emergency department.
On January 10, 2013, Mayor Michael Bloomberg announced a set of recommendations intended to guide opioid analgesic prescribing in New York City emergency departments. The intent and scope of these guidelines are discussed through an interview by an emergency medicine fellow with an expert in emergency medicine pain management and one of the authors of the guidelines. The guidelines are appended to the commentary.

Case ReportsVery-high-dose methadone with minimal toxicity and inadequate pain control in a hospice patient with cancer.
A case is reported of a 48-year-old Caucasian male who was admitted to hospice care with metastatic cancer of the larynx. The patient required very high methadone doses and experienced little opioid toxicity. The pharmacodynamics and pharmacokinetics of methadone are discussed in the context of this patient experience.
