Oportunidades de mejora del servicio de metadona en atención primaria, desde el punto de vista profesional

Objective: To identify and prioritize improvement opportunities, according to the European Foundation for Quality Management model (EFQM) model, of the methadone dispensing service in Andalusian Primary Health Care, from the point of view of professionals. Method: Delphi consensus method, implemented from September 2007 to March 2008 by means of three rounds of interviews with questionnaires administered by electronic mail to 39 professionals. The Panel of experts was made up of Dispensers and Prescribers of methadone as well as Coordinators of welfare services from the Methadone Treatment Program (MTP). Selection criteria were: Being in active employment with a minimum of 3 years experience. Sample diversification variables: Professional role, geographical environment and type of habitat. Recruitment: By means of key professional bodies from different institutions. Results: 48 improvement opportunities were identified. Thirteen of these obtained a high level of agreement in the final round. According to the EFQM model, the dimensions that obtained the most consensus in relation to improving the care service were: Leadership, Alliances and Resources. The dimension that caused the greatest disagreement was Processes. Conclusions: In spite of its having been implemented since 1997 in Andalusian Primary Health Care, the methadone dispensing service is at an implementation phase, rather than what could be classed as a fully deployed stage

Apoyo social a drogodependientes en programa de mantenimiento con metadona en una prisión

Goal: To learn more about the social support available to patients participating in a prison methadone maintenance program (PMM). Methodology: Descriptive, with controls. Setting: A penitentiary in Albolote (Granada) Population Sample: The total prison population was 1,579; 364 patients were included in the PMM; 35 were female and 329 were male. 60 patients, 7 women and 53 men, were used as cases. 30 non-drug dependent prisoners, 3 women and 27 men, were the control group. They had no antecedents of problems with drug addiction. Interventions: Interviews with cases and controls to learn about their addictive antecedents, family structure, socio-economic level, and a hetero-applied MOS questionnaire was completed. Percentages of each social support variable were obtained and compared using the chi-squared technique. Results: The overall support received is low in 38 cases (74.5%) and in 9 controls (30%): p = 0.0001. OR 0.1466, confidence interval at 95% (0.0538-0.3989). Support received is normal in 13 cases (25%) and 21 controls (70%): p = 0.0007. OR 0.69, confidence interval at 95% (0.44-0.93). All of the variables were statistically significant for non-drug addicts, except for emotional support, which was the same for both groups. Conclusion: The perception of inmates participating in the methadone maintenance program was that they received less social support than the non-drug dependent inmates.

Efeitos da metadona ou do neostigmine, associados à lidocaína administrados pela via epidural em cães

Seis cães adultos, de raças e sexos variados, com peso de 13,3±3,4kg (média±DP), foram utilizados no estudo. Os animais foram tranqüilizados com acepromazina (0,1mg/kg, IV) e, após 30 minutos, foram aleatoriamente submetidos à anestesia epidural com um dos seguintes tratamentos: lidocaína 2% 0,25ml/kg (controle); neostigmine 0,01mg/kg+lidocaína (NEO); metadona 0,3mg/kg+lidocaína (MET). Todos os animais foram submetidos aos três tratamentos com intervalo mínimo de uma semana. Foram mensuradas as freqüências cardíaca (FC) e respiratória (FR), a pressão arterial sistólica (PAS), o tempo para a perda do reflexo interdigital, a duração e a altura do bloqueio sensitivo, durante um período de 90 minutos. Não houve diferença significativa entre os tratamentos nos valores de FC, PAS e FR, bem como na duração do bloqueio sensitivo e no tempo para a perda do reflexo interdigital. No grupo MET, houve diminuição de FC dos 30 aos 90 minutos em relação ao valor basal. Bloqueio sensitivo mais cranial também foi observado em MET. A associação de neostigmine ou metadona não prolongou o período hábil de anestesia epidural produzido pela lidocaína em cães. A metadona, mas não o neostigmine, parece estender mais cranialmente o bloqueio epidural pela lidocaína.

Efeitos sedativo e cardiorrespiratório da administração da metadona, isoladamente ou em associação à acepromazina ou xilazina, em gatos

Six cats weighting 3.3±0.3 kg were randomly allocated to 6 treatments, with at least one-week intervals. The cats received intramuscular administration of physiological saline (control), methadone (0.3 mg/ kg), acepromazine (0,1 mg/kg), xylazine (1.0 mg/kg), acepromazine (0.05 mg/kg) plus methadone (0.3 mg/kg) or xylazine (0.5 mg/kg) plus methadone (0.3 mg/kg). Heart rate (HR), respiratory rate (RR), indirect systolic arterial pressure (SAP), rectal temperature, sedation score and pedal withdrawal reflex were evaluated before (baseline) and at selected intervals after treatment administration for 90 minutes. Respiratory rate, HR and rectal temperature decreased in cats given xylazine or xylazine plus methadone. In 1 out of 6 cats given xylazine and 2 out of 6 cats given xylazine/methadone, pedal withdrawal reflex was absent. In cats given 0.1 mg/kg of acepromazine, SAP decreased compared to baseline. Sedation scores were greater in cats given xylazine or xylazine plus methadone. Methadone alone or in combination with acepromazine did not produce a satisfactory degree of sedation and resulted in signs of excitement in some of the cats. Methadone alone or combination with acepromazine was not considered an effective protocol when moderate to deep sedation is required in cats. Methadone in combination with xylazine produces moderate to deep sedation, being this effect comparable to that achieved with a higher dose of xylazine alone.

Efeitos cardiorrespiratórios da metadona, pelas vias intramuscular e intravenosa, em cadelas submetidas à ovariossalpingo-histerectomia

Methadone is a little used opioid in veterinary practice, and there are still questions about its use. The objective of this study was to evaluate the effects of intramuscular (IM) or intravenous (IV) administration of methadone on cardiopulmonary parameters and times of extubation and recovery in female dogs submitted to ovariohysterectomy. Sixteen adult female dogs were used and premedicated with levomepromazine (0.6mg/kg, IM). After 20 minutes, propofol (5mg/kg, IV) was used for induction and anesthesia was maintained with isoflurane. After 10 minutes, methadone at 0.3mg/kg was administered intravenously in IVG and intramuscularly in IMG. The measurement of heart (HR) and respiratory rates (RR), median arterial pressure (MAP), esophagic temperature (ET) and concentration of end-tidal carbon dioxide (PE'CO2) was performed immediately before the administration of the opioid (T0), after 20 minutes (T1) and then at 10-minute intervals (T2, T3, T4 and T5). The statistical analysis used was profile (5%). HR, APM, RR, PE'CO2, BT and SpO2 did not differ significantly among times or between groups at any time. Times of extubation and recovery were higher in IVG. It is possible to conclude that IV and IM administration of methadone did not produce changes in the cardiorespiratory parameters of that specie.
