Evaluation of a spring-loaded syringe driver for the subcutaneous administration of narcotics.

A simple spring-loaded syringe driver was tested for the subcutaneous administration of narcotic analgesics and antiemetics. With concentrations of 2 to 10 mg/mL of hydromorphone and 10 to 50 mg/mL of morphine, the infusion rate during preclinical testing was 1.01 +/- 0.1 mL/hr (range 0.70-1.2 mL/hr). The rate of infusion was not modified by the concentration of narcotic in solution. Clinical trials were performed with morphine in 17 patients, and with hydromorphone in 11 patients. The duration of the infusion was 21 +/- 11 days. The most frequent reason for discontinuation was death (22 cases). The average duration of the site of infusion was 6.3 +/- 4 days. When used subcutaneously, the rate of infusion of the device was 1 +/- 0.15 mL/hr (range 0.70-1.30 mL/hr). Patients and nurses were satisfied with the simplicity and safety of the device. Cost analysis shows that this device is significantly less expensive than currently available portable infusion devices. We conclude that the Medifuse Pump is an inexpensive, safe and effective device for the subcutaneous infusion of narcotics and antiemetics.

The Edmonton Symptom Assessment System (ESAS): a simple method for the assessment of palliative care patients.

We describe a simple method for the assessment of symptoms twice a day in patients admitted to a palliative care unit. Eight visual analog scales (VAS) 0-100 mm are completed either by the patient alone, by the patient with nurse's assistance, or by the nurses or relatives at 10:00 and 18:00 hours, in order to indicate the levels of pain, activity, nausea, depression, anxiety, drowsiness, appetite, and sensation of well-being. The information is then transferred to a graph that contains the assessments of up to 21 days on each page. The sum of the scores for all symptoms is defined as the symptom distress score. The Edmonton Symptom Assessment System (ESAS) was carried out for 101 consecutive patients for the length of their admission to our unit. Of these, 84% were able to make their own assessment sometime during their admission. However, before death 83% of assessments were completed by a nurse or relative. Mean symptom distress score was 410 +/- 95 during day 1 of the admission, versus 362 +/- 83 during day 5 (p less than 0.01). Mean symptom distress scores throughout the hospitalization were 359 +/- 105, 374 +/- 93, 359 +/- 91 and 406 +/- 81 when the ESAS was completed by the patient alone, patient with nurse's assistance (p = N.S.), nurse alone (p = N.S.), or relative (p less than 0.01) respectively. We conclude that this is a simple and useful method for the regular assessment of symptom distress in the palliative care setting.

Hypodermoclysis (HDC) for symptom control vs. the Edmonton Injector (EI).

Hypodermoclysis (HDC) is a well-known method of providing symptom control in terminally ill patients. In this article we make reference to two previous reports describing our use of HDC and a new method of subcutaneous narcotic delivery called the Edmonton Injector (EI). The rationale for using HDC mainly for rehydration and the EI when subcutaneous narcotics are needed is explored. The controversy surrounding the treatment of dehydration in the terminally ill is examined. Finally, the advantages on our palliative care unit of the convenience, increased flexibility, and cost and time saving of these two treatment methods are discussed.

Rectal, buccal, and sublingual narcotics for the management of cancer pain.

We review current knowledge on the rectal, buccal, and sublingual routes of narcotic administration as potential alternatives to oral, intramuscular, intravenous, and subcutaneous administrations of narcotics for the management of cancer pain. Most of the experience reported in the literature is based on the use of rectal, sublingual, and buccal narcotics for the management of acute pain syndromes. Preliminary evidence suggests that both morphine sulfate and chlorhydrate can be administered rectally because there is acceptable absorption with this route even if considerable interpersonal variation exists. There are no controlled trials on the long-term use of rectal morphine for cancer pain. There are very few reports on the clinical effects of sublingual and buccal morphine, and pharmacokinetic data are often debatable. There is evidence to justify further research into all three routes of narcotic administration. At the moment rectal use is justified in clinical trials in cancer patients, but there are not enough data on the pharmacokinetics of different narcotics when administered by the buccal or sublingual routes.

Symptom control during the last week of life on a palliative care unit.

A recent report suggested that more than 50% of terminal cancer patients have physical suffering that requires sedation in the last days of life. To evaluate this finding on our 14-bed palliative care unit, a retrospective analysis of 100 consecutive patients admitted for 6 days or more was carried out. Information was collected on major symptoms requiring treatment, symptom control at admission and during each of the last 7 days of life, medications used, and changes that may have contributed to sedation. Of the 100 patients, 99 had pain, 46 had dyspnea, 71 had nausea, and 39 experienced delirium. Visual Analogue Scores (VAS) were done twice a day in all patients; mean pain showed a change from 31 +/- 24 on Day 6 to 24 +/- 19 on day of death (DOD) (p less than 0.05); nausea from 19 +/- 18 on Day 6 to 13 +/- 9 on DOD (p less than 0.01); drowsiness from 51 +/- 28 on Day 6 to 85 +/- 45 on DOD (p less than 0.001); symptom distress score from 49 +/- 11 on Day 6 to 52 +/- 9 on DOD (p less than 0.01). On the day of admission (DOA), 69% of VAS were done by the patient and 28% by the nurse as compared to 8% by the patient and 90% by the nurse on DOD. Level of consciousness on DOA was alert (72%), drowsy (28%), unresponsive (0%) and by DOD was alert (2%), drowsy (41%), unresponsive (57%).(ABSTRACT TRUNCATED AT 250 WORDS)

A controlled trial of megestrol acetate on appetite, caloric intake, nutritional status, and other symptoms in patients with advanced cancer.

This double-blind, cross-over trial was designed to assess the effects of megestrol acetate (MA) on cancer-induced cachexia. Forty consecutive malnourished patients with advanced non-hormone-responsive tumors receiving no antineoplastic treatment were randomized to receive MA 480 mg/day versus placebo for 7 days. During day 8, a cross-over was made until day 15. Appetite, pain, nausea, depression, energy, and well-being were assessed with a visual analog scale (0 to 100 mm) at 9:00 AM and 4:00 PM during days 6, 7, 13, and 14. Weight (W;kg), tricep skinfold (TS; mm), arm circumference (AC; cm), and calf circumference (CC; cm) were measured at days 1, 8, and 15. Caloric intake (CI; Kcal/day) was determined during days 6, 7, 13, and 14. In 31 evaluable patients, the percentual difference in appetite at 9:00 AM, appetite at 4:00 PM, energy, and well-being after MA was +15.1, +14, +3.2, and +5.2, versus -12 (P = 0.03), -5.1 (P = 0.015), -10 (P = 0.024), and -8.3 (not significant) after placebo. Percentual difference in W, TS, AC, and CC after MA was +0.2, +1, -0.1, and +0.4 versus -0.8 (P = 0.03), -0.8 (P = 0.001), -0.3 (not significant), and -0.5 (P = 0.04) after placebo. CI during MA was 3480 +/- 1574 (48-hour intake), versus 2793 +/- 1542 (P less than 0.001) during placebo. Patients and investigators blindly chose MA in 20 (66%, P = 0.023) and 28 cases (92%, P less than 0.001), placebo in eight and two cases, and made no choice in three and one cases, respectively. Toxicity consisted of mild edema and nausea in three and two cases, respectively. After mean follow-up of 27 +/- 13 days, on an open basis, an average increase in W and AC of 4.8 +/- 1.7 kg and 2.8 +/- 1.7 cm was observed, respectively. The authors conclude that MA is a powerful appetite stimulant with subjective and objective effects on nutritional status.

Hypodermoclysis for the administration of fluids and narcotic analgesics in patients with advanced cancer.

Fifty-eight consecutive patients with advanced cancer who required parenteral hydration were treated with hypodermoclysis. A solution of two-thirds 5% dextrose and one-third saline was used in all cases at a rate of 20-100 cc/hr, with 750 units of hyaluronidase per liter, and 20-40 mEq KCl/L were administered in all patients. In 38 patients, morphine (21 cases) or hydromorphone (17 cases) were added. The mean duration of infusion and volume were 14 +/- 9 days and 1.3 +/- 0.8 L/day, respectively (range, 0.5-3 L/day). Mean dose of KCl was 25 +/- 8 mEq/L. The reason for discontinuation was death in 43 cases, oral hydration in 12 cases, and need for fluid restriction in 3 cases. Toxicity consisted in local infection in two cases and bruising in two cases. We conclude that hypodermoclysis is a safe and effective method of hydration in patients with advanced cancer.

Effects of morphine on the dyspnea of terminal cancer patients.

We report an open, uncontrolled study designed to assess the effects of subcutaneous (SC) morphine on dyspnea of terminal cancer. Twenty patients with dyspnea caused by restrictive respiratory failure received an SC dose of morphine of 5 mg (5 patients who were not receiving narcotics), or equivalent to 2.5 times their regular dose (15 patients who were receiving narcotics for pain). Dyspnea (D) and pain (15 cases) were measured before the dose and every 15 min for 150 min after the injection using a visual analog scale 0-100. Respiratory rate (RR), respiratory effort (RE) (score 1-6), arterial saturation of O2 (SO2) and end-tidal PACO2 were determined before and 45 min after SC morphine. D, RR, RE, SO2, and PACO2 were 68 +/- 32, 32 +/- 7; 3.5 +/- 1.8, 87 +/- 10, and 31 +/- 12, respectively, before SC morphine, and 34 +/- 25 (P less than 0.001), 31 +/- 9 (P:NS), 3.2 +/- 1.9 (P:NS), 86 +/- 11 (P:NS), and 33 +/- 9 (P:NS), respectively, 45 min after SC morphine. Nineteen of 20 patients (95%) reported improved dyspnea after morphine. We conclude that morphine appears to improve dyspnea without causing a significant deterioration in respiratory function in terminal cancer patients. Double-blind placebo controlled studies are needed in this population.

Ambulatory infusion devices in the continuing care of patients with advanced diseases.

Until recently, patients who required hydration or parenteral administration of narcotics or antiemetics remained in hospitals until death. The period of admission, which varied between days and months, resulted in a decreased quality of life for the patient and family. With the development of portable infusion pumps, patients with these needs can now be safely discharged home for long periods of time, thereby significantly reducing the cost of medical care and improving quality of life for patients and families. The demonstration that the subcutaneous route is safe and effective for the administration of narcotics, antiemetics, and fluids has made home discharges particularly easy and simple. New devices even allow patients to self-administer extra doses of narcotics when needed. Each institution needs to carefully consider the different infusion devices available before starting a home parenteral administration program. The most important factors to consider are cost, health professional education, patient and family education, a system of monitoring in the home and safety. The high cost of portable pumps and supplies are a major obstacle for the establishment of large programs for home parenteral drug administration. More research is needed to better characterize the pharmacokinetics of different drugs when administered subcutaneously, and to develop simpler and more effective portable infusion devices. The results of this research will have a major impact on the quality of life of patients and their families.

Palliative care in a cancer center: results in 1984 versus 1987.

We reviewed the charts of 48 consecutive patients treated by our Palliative Care Team (PCT) during 1984 and compared these results with 50 consecutive patients treated during 1987. The composition of the PCT did not change between 1984 and 1987. The median equivalent daily dose of parenteral morphine (MEDD) before referral, after initial treatment by the PCT, and at the maximum prescribed by the PCT were 43 mg, 48 mg, and 96 mg in 1984, respectively, versus 60 mg (p less than 0.03), 60 mg (p less than 0.03), and 120 mg (p less than 0.12) in 1987, respectively. Seventeen of 43 patients were receiving mild narcotics in 1984 versus 7 of 48 patients in 1987 (p less than 0.01). Parenteral narcotics were used initially in 2% of patients in 1984 versus 46% of patients in 1987 (p less than 0.001). Poor pain control after the initial treatment was observed in 42% of patients in 1984 versus 26% in 1987 (p less than 0.01). Our results suggest that patients are being treated more aggressively by their physicians before referral to the PCT in 1987, that our PCT is using more aggressive initial treatment than in 1984, and that, notwithstanding these changes, there is still a significant proportion of patients in whom pain cannot be controlled before death. These results suggest that more research is necessary to better define intractable pain syndromes and develop adequate treatments for them.

Treatment of pain and other symptoms in cancer patients: patterns in a North American and a South American hospital.

The charts of 200 consecutive patients with cancer pain admitted to a major teaching hospital in Edmonton, Canada (n = 100) and in Buenos Aires, Argentina (n = 100) were reviewed to assess the differences between North American (NA) and South American (SA) facilities in patterns of treatment of pain and other symptoms. Criteria for eligibility and methods were identical in both hospitals. Characteristics of patients (age, sex, primary tumor, reason for admission) and attending staff were similar between both hospitals. Mean daily equivalent doses of parenteral morphine (mg) were 44 +/- 26 and 9 +/- 10 in NA and SA, respectively (p less than 0.001). Patients in NA, received narcotics every 4 hr and on a regular basis more frequently than in SA. The types of narcotics and the use of adjuvant drugs were significantly different between NA and SA. Nonpharmacologic treatments, antiemetics, and laxatives were more frequently used in NA. These results suggest that there are significant differences in symptomatic management of advanced cancer between institutions in NA and SA.

Social and demographic characteristics of patients admitted to a palliative care unit.

In this retrospective study we reviewed the charts of 169 consecutive admissions to the Palliative Care Unit, Edmonton General Hospital. Demographic and social characteristics of patients were assessed in order to determine the likelihood that the patients could be managed at home according to currently available services. The mean age of the population was 65 +/- 12 years, 97 (57%) were women, they had a variety of cancers with major prevalence of the most frequent adult tumors, and 72% of patients were coming from acute care hospitals. Each patient had an average of 2.7 +/- 1.8 children (median = 3), a mean of 0.18 +/- 0.6 dependents (median = 0), a mean of 1 +/- 0.9 support persons at home (median = 1), and a mean of 2.6 +/- 1 support persons outside the household (median = 2). Of a total of 119 main caregivers who lived in the same household as the patient, 69 (58%) were not able to take care of the patient. Only 27 patients (16%) considered that there were major financial problems, and all 169 patients had universal health care available (95 patients had additional private health care coverage). Of 125 patients who were asked where they preferred to die, 112 (90%) stated that they did not want to die at home. Our data suggest that the lack of family support and lack of intensive home care services are the main obstacles to home care of terminally ill cancer patients in our province. Home care services as currently available are not able to care for a large number of patients with terminal cancer. More prospective research into this subject is badly needed.
