Sixty patients who were scheduled to have an elective total hip or knee arthroplasty were randomly assigned to one of three groups of twenty patients each before operation with spinal anesthesia. A double-blind technique was used throughout the study. The patients in Group I (control group) received hyperbaric 1 per cent tetracaine with epinephrine as the subarachnoid spinal anesthetic; the patients in Group II (morphine group), hyperbaric 1 per cent tetracaine with epinephrine and a single subarachnoid dose of Duramorph (morphine sulphate), 0.5 milligram; and those in Group III (Dilaudid group), hyperbaric 1 per cent tetracaine with epinephrine and a single subarachnoid dose of Dilaudid (hydromorphone hydrochloride), 0.002 milligram per kilogram of body weight. During the first twenty-four hours after the operation, the patients in Group II and Group III had significantly less pain compared with those in Group I. This was shown by the use of a visual linear-analog pain scale (p less than 0.05), the patients' ratings of the quality of relief of pain (p less than 0.02), and comparative measurements of the pain-altering medications that were used (p less than 0.05). The patients in Group II and Group III did not have any more complications or side effects than those in Group I. There was no significant difference in the quality and duration of analgesia between Group II and Group III.

In a prospective study, including fifty consecutive patients with acute ureteral-stone pain, the patients were randomly distributed into two groups for treatment. There were given either an intravenous injection of indomethacin (Confortid) 50 mg, or a subcutaneous injection of 2 mg hydromorphine chloride-atropine (Dilaudid-atropin 1 ml). Patients in the latter group also received a suppository of prochlorperazine (Stemetil) 25 mg. The analgesic effect of the two drugs did not differ significantly. Indomethacin was quicker acting, probably due to the intravenous route of administration. The side effects were alike but those caused by indomethacin had a tendency to be milder and of shorter duration.

We report two cases of children with metastatic bone disease who received strontium-89 intravenously. An 11-year-old boy with stage IV neuroblastoma received 50 microCi/kg of strontium-89. He had a good response, and his pain abated to the point that he could be taken off IV Dilaudid and was discharged from the hospital. A 7-year-old girl with the diagnosis of squamous cell carcinoma of the lung disclosed minimal increased uptake on a bone scan. Following the strontium-89 therapy, she did not have any significant improvement in pain, probably due to the minimal osteoblastic activity evidenced by the minimal abnormalities on the bone scan. Until this report there has been no reported case of using strontium-89 in the treatment of children with metastatic disease.

Epidural opioid analgesia can offer advantages over intravenous administration, however, opioid-related side effects are common after epidural administration. We studied the effect of adding nalbuphine (NB), an opioid agonist-antagonist, to hydromorphone (HM) for patient-controlled epidural analgesia (PCEA) in 78 healthy women after elective cesarean delivery. Patients were randomly assigned to one of four treatment groups. The control group received preservative-free HM (Dilaudid) alone, 0.075 mg/mL, while the three study groups received HM, 0.075 mg/mL, containing preservative-free NB (Nubain) 0.02, 0.04, or 0.08 mg/mL. Intraoperatively, all patients received epidural bupivacaine 0.5%. Postoperatively, a patient-controlled anesthesia (PCA) device was connected to the epidural catheter and programmed to deliver a 3-mL loading dose of the analgesic solution. Subsequently, patients could self-administer 2 mL bolus doses on demand with a 30-min lockout interval. Patients were encouraged to ambulate approximately 8 h after surgery, and PCEA therapy was discontinued when a clear liquid diet was tolerated. Visual analog scale scores were used to assess pain at 8-h intervals while using PCEA therapy. Although the overall incidences of nausea (19%-35%) and pruritus (32%-62%) were similar in all four groups, the addition of NB decreased the need for bladder catheterization. The highest NB concentration resulted in increased PCA demands during the 32-h study period. In conclusion, the combination of HM 0.075 mg/mL and NB 0.04 mg/mL resulted in lower nausea scores and a decreased incidence of urinary retention compared with HM alone, without increasing the opioid analgesic requirement.

Intramuscular (i.m.) injection with meperidine is the most common analgesic approach to treat postoperative pain in Taiwan. Hydromorphone (Dilaudid) can provide very potent and rapid analgesic effect through subcutaneous (s.c.) injection. Although hydromorphone is widely used in North America, no study has compared the analgesic efficacy, side effect profiles and patients' satisfaction with the method of injection of hydromorphone s.c. and meperidine i.m. for the immediate post-operative analgesia. In this randomized and double-blind study, 60 female patients scheduled for abdominal total hysterectomy were treated either with 1 mg hydromorphone s.c. (n = 30) or 50 mg meperidine i.m. (n = 30) when they regained consciousness and asked for analgesic treatment in the recovery room. Visual analogue score (VAS) of wound pain was obtained at 0, 10 and 30 min after injection by a blinded observer. The occurrence and severity of nausea, vomiting, dizziness, drowsiness, flatus passage and respiratory depression were recorded. Post-operative analgesia in the ward was maintained by patient-controlled analgesia (PCA) with intravenous morphine. Time to first PCA demand, the number of demands, delivery, delivery/demand ratio and 24 h morphine consumption were documented. We found that VAS was reduced at 10 min and, to a greater extent, at 30 min postinjection in both groups but with no significant difference between the two groups. The occurrence and severity of side effect profiles were similar in both groups except that dizziness was more frequently observed after meperidine injection. Delivery, demand, delivery/demand ratio and 24 hr morphine consumption by PCA were not significantly different between the two groups. Time to first PCA trigger was also similar. Patients receiving hydromorphone s.c. injection exhibited higher satisfactory score than those receiving meperidine i.m. injection. Hydromorphone 1 mg, injected subcutaneously, was as effective as intramuscular meperidine 50 mg while permitting more favorable injection technique and fewer side effects. We suggest that subcutaneous hydromorphone is a good alternative to intramuscular meperidine for postoperative analgesia in the recovery room.

We describe 2 patients, one with cervical dystonia (CD) combined with focal hand dystonia (writer's cramp) and another with idiopathic CD, who were unresponsive to oral medications and became resistant to botulinum toxin type A and B injections. Both patients were successfully treated with high cervical (C1-3) continuously infused intrathecal baclofen (ITB). Neck range of motion (ROM) was measured by using a 3-dimensional electromagnetic cervical ROM system. Pain, disability, and severity were assessed by using the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS). The patient with CD and writer's cramp did well on a continuous baclofen dose of 186.1 microg/d. Her total TWSTRS score improved significantly, her electromagnetic measurements showed an increased in total neck flexion and extension, and her handwriting improved. Unfortunately, this patient (a heavy smoker) developed small cell carcinoma of the lung and died 9 months after her pump was placed. Total TWSTRS score and electromagnetic measurements also significantly improved after pump implant in the patient with CD. He continues to do well on a periodic bolus dose using a combination of 50 microg of baclofen and 25 microg of hydromorphone (Dilaudid) every 4 hours. Our findings suggest the potential usefulness of this therapy in other patients with focal dystonia. To our knowledge, this is the first reported successful treatment of CD and CD combined with writer's cramp with high cervical continuously infused ITB.

The infusion pain pump has been a valuable addition to postoperative pain management in plastic and reconstructive surgery. Concerns have been raised regarding the potential ischemic or infectious complications of placing a catheter beneath the operative site for infusion of local anesthesia (+/- epinephrine). The purpose of this review is to document our experience with this form of postoperative pain control in plastic surgical procedures. Thirty-six consecutive transverse rectus abdominis muscle (TRAM) flap breast reconstruction patients were reviewed and included in the series (16 left, 10 right, and 10 bilateral). The average age was 52 years, and 4 patients had a simultaneous symmetry procedure. The cohort was divided into those with a postoperative pain pump versus those without a pain pump. Data points queried included type, route, and amount of narcotic administered per day in the postoperative period, as well as complications. All patients received patient-controlled analgesia (PCA) (morphine, n = 34; meperidine (Demerol, Sanofi-Synthelabo), n = 1; hydromorphone hydrochloride (Dilaudid, Abbott Pharmaceutical) n = 1). The pain pump was used in 16 patients (bupivacaine (Marcaine, AstraZeneca, n = 16). It was typically infused starting postoperatively at a rate of 4 mL/d and discontinued on postoperative day 2. Supplemental intravenous narcotics were required in 12% (n = 2/16) of patients with a pain pump versus 35% (n = 7/20) in those patients without a pain pump. There were no significant differences in the average number of days the PCA was used (1.8 days with a pain pump versus 2.2 without), and patients with the pain pump started postoperative medications slightly earlier (1.8 versus 2.0 days). PCA requirements were significantly lower in those patients with the pain pump. The average days to discharge for patients with a pain pump were 3.4 compared with 4.7 days in those patients without the pain pump. There were no differences in donor-site or breast complications. The postoperative pain pump has been useful in reducing the intravenous narcotic requirements and length of stay in patients following TRAM flap breast reconstruction. There were no flap, donor-site, or implant complications related to the presence of the catheter. Cost-effectiveness and patient satisfaction data would be interesting.

Over the past decade, the misuse and abuse of opioid medications in the United States has risen dramatically. Although data show a substantial variation in the nonmedical use of individual opioids, relatively little is known about risk factors for the nonmedical use of specific opioid products. This study compared the prevalence and correlates of the nonmedical use of oral immediate-release hydromorphone (marketed under the brand name of Dilaudid), versus that of hydrocodone combination products using a nationally representative sample of the civilian noninstitutionalized United States population aged 12 years or older. Data were from the 2003 National Survey on Drug Use and Health. An estimated 31.3 million individuals reported lifetime nonmedical use of an opioid analgesic. Of these, 2.9 percent reported lifetime nonmedical use of Dilaudid, and 51.9 percent reported lifetime nonmedical use of hydrocodone combination products exclusive of nonmedical Dilaudid use. Nonmedical Dilaudid users were likely to be older, Caucasian, and to have reported a higher lifetime prevalence of heroin, cocaine and injection drug use, as well as nonmedical use of other opioids. Nonmedical Dilaudid users were at higher risk for engaging in more serious substance abuse-related behaviors than those who reported lifetime nonmedical use of hydrocodone combination products.

You received a call advising that Mr S. H. Irk was in the emergency room having considerable wound pain following an above-knee amputation you performed 6 months ago. You discharged him from your clinic 6 weeks postoperatively to his primary care physician, still complaining of more pain than usual. Your examination, clinical lab tests, and X-rays do not reveal any serious problems, but he is writhing in pain and begging for relief. Mr Irk has been to a number of different physicians in the interlude including a chiropractor, a pain specialist, several primary care physicians, and a psychiatrist without relief. He has braced up with increasing amounts of analgesics, the latest of which was oral Dilaudid. His last source of pain meds on the street has dried up. You admit him with orders for analgesics. What should your treatment plan be?

Opioids are the cornerstone of palliative pain management. Opioids work on the mu-opioid receptor as an agonist for the treatment of pain. Repeated exposure to opioids over time can lead to undesired desensitization of the antinociceptive receptor while sensitizing the N-methyl-D-aspartate (NMDA) pathway, causing a paradoxical effect where the treatment of pain creates more sensitivity to certain stimuli. This phenomenon is known as opioid-induced hyperalgesia (OIH). Methadone, a synthetic opioid, may be more effective for pain and offers advantages over other opioids in specific clinical situations due to its partial antagonistic effect on the NMDA pathway. We describe a unique case where as needed (prn) and continuous intravenous (IV) methadone was effective in relieving OIH caused by high doses of IV Dilaudid for intractable cancer pain at the end of life. Given its unique pharmacokinetics, effective pain control, and the prevention of suffering from OIH, methadone should be considered earlier on in palliative pain management, especially in those patients predicted to require high levels of opioid dosing.
