Oral sedation allows for comfort and amnesia during office surgery.

Surgical procedures commonly associated with parenteral sedation or general anesthesia were completed in an office operating room with local anesthesia and oral medication. Diazepam and alprazolam were used in combination to produce a relaxed state, allowing local anesthesia to be instilled. Surgery was completed successfully in all patients, and no untoward effects were seen in the patients. Amnesia was associated with the drug combination, and a protective action of the long-lived drugs against lidocaine toxicity is theorized.

Effect of narcotic pain reliever on pulp tests in women.

The purpose of this study was to determine the effect of one dose of a common narcotic-based pain reliever (Vicodin) on a battery of oral sensitivity tests across time in women. Fifteen Caucasian women randomly were given an oral dose of 10 mg of hydrocodone/1000 mg of acetaminophen or placebo in a double-blind, cross-over design. At baseline (before drug) and after 2, 4, and 8 h each subject was evaluated for sensitivity thresholds with four tests around an experimental tooth: (a) electric pulp tester applied to exposed root; (b) electric pulp tester on adjacent mucosa; (c) increasing probe pressure (grams) on adjacent mucosa; and (d) decreasing cold probe (degrees C) on the exposed root. The outcomes of all tests were not statistically different between drug and placebo treatments at any time point (p > 0.05). These results suggest that a systemic dose of hydrocodone/acetaminophen has little impact on healthy pulp or mucosa sensitivity in women as measured by common diagnostic tests.

Rofecoxib versus hydrocodone/acetaminophen for postoperative analgesia in functional endoscopic sinus surgery.

OBJECTIVES/HYPOTHESIS: Functional endoscopic sinus surgery (FESS) is less invasive and more tissue sparing than extirpative techniques, with an assumed benefit of diminished postoperative pain. Oral opioids are commonly prescribed after sinus surgery but are associated with adverse effects, including gastrointestinal and neurologic symptoms. Nonopioid analgesics have been suggested to offer similar pain control efficacy with fewer adverse effects. STUDY DESIGN: To investigate postoperative analgesia in FESS, a prospective randomized, double-blinded comparison of hydrocodone/acetaminophen 7.5/750 mg (an opioidderivative) with rofecoxib 50 mg (a cyclooxygenase-2 inhibitor) was performed. METHODS: Forty subjects were enrolled, of which 28 successfully completed the study. Subjects recorded peak pain levels and requirement for rescue analgesia on the day of surgery and for 4 days thereafter. On postoperative day 5, subjects completed an exit survey in which adverse effects and overall satisfaction with pain control were recorded. RESULTS: In this study, there were no statistical differences in peak pain levels between the groups at any point in the postoperative period, regardless of extent of surgery. Adverse effect profiles were also similar for the two groups. CONCLUSIONS: The use of nonopioid analgesics after FESS may provide similar pain control to oral opioids.

Trends and geographic variation of opiate medication use in state Medicaid fee-for-service programs, 1996 to 2002.

BACKGROUND: Although studies have documented hospital and surgical service geographic variability, prescription use geographic variability is largely unknown. Opiate pain medications are widely used, particularly because the promulgation of clinical guidelines promoting aggressive pain treatment. This study describes temporal and interstate variability in aggregate prescription opiate medication use within U.S. Medicaid programs. METHODS: A dataset of 49 states' fee-for-service (FFS) Medicaid prescription drug dispensing records from 1996 to 2002 was compiled and used to quantify medication dispensing examining all opiates, controlled release oxycodone, and methadone. The defined daily dose (DDD) per 1000 FFS Medicaid adult enrollees per day was calculated for all opiate medication categories. A market basket of nonpain prescription medications was constructed for comparison. Rates, trends, and the coefficient of variation were determined overall, by year and for each state. RESULTS: From 1996 to 2002, overall use of opiate pain medications increased 309%. The market basket use increased 170%. Total opiate dispensing varied widely from state to state, with a range of 6.9 to 44.1 DDD/1000/d in 1996, and 7.1 to 165.0 DDD/1000/d (a 23-fold difference) in 2002. The coefficient of variation was 49.6 in 2002. Controlled release oxycodone and methadone had a greater rate of increase compared with all opiates. CONCLUSIONS: The dispensing of opiate medications in Medicaid programs increased at almost twice the rate of nonpain-related medications during the 7-year study period. Large, unexplained geographic variation in aggregate use exists. The impact of Medicaid cost-containment strategies on utilization and outcomes should be investigated.

Pediatric body packing: drug smuggling reaches a new low.

The case of a 6-year-old boy presenting with severe clinical manifestations of an opioid intoxication and who is discovered to be an international "body packer" is presented and discussed. This article is the first to report on the phenomenon of body packing in young children. It also highlights the use of prescription opioids as cargo, which has not previously been addressed in the literature.

The availability of web sites offering to sell opioid medications without prescriptions.

OBJECTIVE: This study was designed to determine the availability of web sites offering to sell opioid medications without prescriptions. METHOD: Forty-seven Internet searches were conducted with a variety of opioid medication terms, including "codeine," "no prescription Vicodin," and "OxyContin." Two independent raters examined the links generated in each search and resolved any coding disagreements. The resulting links were coded as "no prescription web sites" (NPWs) if they offered to sell opioid medications without prescriptions. RESULTS: In searches with terms such as "no prescription codeine" and "Vicodin," over 50% of the links obtained were coded as "NPWs." The proportion of links yielding NPWs was greater when the phrase "no prescription" was added to the opioid term. More than 300 opioid NPWs were identified and entered into a database. CONCLUSIONS: Three national drug-use monitoring studies have cited significant increases in prescription opioid use over the past 5 years, particularly among young people. The emergence of NPWs introduces a new vector for unregulated access to opioids. Research is needed to determine the effect of NPWs on prescription opioid use initiation, misuse, and dependence.

Complications of intranasal prescription narcotic abuse.

The abuse of drugs via an intranasal route is an increasingly prevalent pattern of behavior. In the past year, a number of patients received care at our institution for complications resulting from the previously unreported phenomenon of intranasal prescription narcotic abuse. This report describes the clinical manifestations of this form of drug abuse in 5 patients. Their symptoms consisted of nasal and/or facial pain, nasal obstruction, and chronic foul-smelling drainage. Common physical findings were nasal septal perforation; erosion of the lateral nasal walls, nasopharynx, and soft palate; and mucopurulent exudate on affected nasal surfaces. In addition, 2 of the 5 patients had invasive fungal rhinosinusitis, which appears to be a complication unique to intranasal narcotic abuse.

A double-blind comparative clinical trial of floctafenine and four other analgesics conducted in general practice.

Three hundred and twelve patients suffering from painful conditions were admitted to a multicentre, double-blind controlled trial, conducted in general practice in which five analgesics--floctafenine (Idarac), paracetamol, aspirin, dihydrocodeine and pentazocine--were compared. Overall ratings of analgesic effect placed floctafenine first in rank order. Floctafenine was statistically significantly superior in effect to pentazocine but not to the other three agents as far as doctor ratings were concerned; and superior to both pentazocine and dihydrocodeine in the opinion of patients. Fewer patients experienced side-effects on floctafenine than on the other four analgesics and this difference between floctafenine and pentazocine, and floctafenine and dihydrocodeine was statistically significant.

The efficacy of rofecoxib 50 mg and hydrocodone/acetaminophen 7.5/750 mg in patients with post-arthroscopic pain.

OBJECTIVE: To compare the efficacy and tolerability of rofecoxib, hydrocodone/acetaminophen 7.5 mg/750 mg (H/A) and placebo in treating pain after arthroscopy of the knee. METHODS: A randomized, double-blind, placebo-controlled, single dose study enrolling patients experiencing moderate or severe pain after knee arthroscopy. Patients with moderate-to-severe postoperative pain received either rofecoxib 50 mg (n = 151), H/A (n = 145), or placebo (n = 147). Pain was measured over 24 h. The primary endpoint was total pain relief at 6 h for rofecoxib 50 mg compared with placebo. RESULTS: H/A (p = 0.003), but not rofecoxib (p = 0.256) was significantly more effective than placebo for total pain relief at 6 h (TOPAR6). Although analgesic onset and peak were significantly better for H/A than for both rofecoxib (p < 0.01, p < 0.05, respectively) and placebo (p < 0.05, p < 0.001, respectively), rofecoxib patients used significantly less rescue analgesia (p < 0.001) over 24 h. Rofecoxib also provided better Brief Pain Inventory Severity (p = 0.008) and Interference Domain (p = 0.045) scores at 24 h compared to placebo and had lower 24-h Pain Severity scores than H/A (p < 0.05). Treatments were generally well tolerated, with no significant difference in the frequency of patient-reported adverse events between groups. CONCLUSIONS: Rofecoxib 50 mg did not provide significantly different pain relief than placebo at 6 h, and the primary endpoint TOPAR was not attained, although it did show several efficacy benefits at 24 h, including a significant opioid-sparing effect. All treatments were well tolerated, with no significant differences observed. The limited efficacy of rofecoxib in this study contrasts to the results of previous surgical studies evaluating rofecoxib, and may be partially explained by the postoperative dosing in this arthroscopic surgical model.

Preoperative "fentanyl challenge" as a tool to estimate postoperative opioid dosing in chronic opioid-consuming patients.

UNLABELLED: When opioids are used for postoperative pain control, it is useful to define the dose-response relationship for analgesia and respiratory depression. We studied 20 chronically opioid-consuming patients having elective multilevel spine fusion. Preoperatively, each patient received a fentanyl infusion of 2 microg x kg(-1) x min(-1) until the respiratory rate was <5 breaths/min. Pharmacokinetic simulations were used to estimate the effect site concentration at the time of respiratory depression and to predict the patient-controlled analgesia settings that would provide an effect-site fentanyl concentration that was 30% of the concentration associated with respiratory depression. Postoperatively, patient-controlled analgesia settings were adjusted to achieve 2-3 demand doses per hour. At steady-state patient-controlled analgesia settings, arterial blood gases and plasma fentanyl levels were measured. Sixteen patients required no adjustment or one patient-controlled analgesia adjustment. The median arterial Pco(2) level was 41 mm Hg and the interquartile range was 39-46 mm Hg. Plasma fentanyl levels demonstrated a significant correlation to the estimated effect-site concentration associated with respiratory depression determined during the preoperative fentanyl challenge. A preoperative fentanyl challenge used with pharmacokinetic simulations may be a useful tool to individualize the administration of analgesics to chronically opioid-consuming patients. IMPLICATIONS: In chronically opioid-consuming patients, doses causing respiratory depression and analgesia may differ from those in opioid-naive individuals. A preoperative infusion of fentanyl, used in conjunction with pharmacokinetic simulation, may be a valuable tool for identifying clinical end-points, such as respiratory depression and analgesia, and individualizing postoperative treatment of pain in patients who chronically consume opioids.

Postoperative epidural morphine for postpartum tubal ligation analgesia.

Women undergoing postoperative postpartum tubal ligation (PPTL) often experience considerable pain. We hypothesized that epidural morphine, as part of a multi-modal analgesic regimen, would decrease postoperative pain and the need for systemic analgesia after PPTL. In a double-blinded study, patients were randomized to receive epidural saline or morphine 2 mg, 3 mg, or 4 mg after epidural anesthesia for PPTL. Postoperatively, ibuprofen 600 mg was administered every 6 h and patients could request acetaminophen 325 mg/hydrocodone 10 mg. The primary outcome variable was time to first request for supplemental analgesia. Verbal rating scores for pain and the incidence and severity of side effects were recorded for 24 h. Morphine group subjects requested supplemental analgesia later and received fewer doses compared with the saline group subjects. Peak cramping and incisional verbal rating scores for pain and the area under the verbal rating scores for pain x time curve for cramping pain were less after epidural morphine compared with saline, but there were no differences among morphine groups. Nausea, vomiting, and pruritus occurred more often in all morphine groups and subjects who received morphine 4 mg required treatment for these side effects more frequently than the saline or morphine 2 mg groups. In conclusion, epidural morphine 2 mg as part of a multi-modal analgesic regimen improved analgesia and decreased the need for supplemental analgesics after PPTL. The need to treat side effects with morphine 2 mg was not increased compared to a regimen of oral acetaminophen/opioid/nonsteroidal antiinflammatory analgesics.
