Prescribing of injectable diacetylmorphine (DAM) for heroin dependence has raised concerns about its safety. In light of various reports by heroin-maintained patients of DAM-related adverse events, and previously established unwanted effects of opioids in pain management, we undertook a survey in February 2001 of a random sample of 132 (127 participated) of 1061 patients prescribed DAM in Switzerland at that time. The purpose was to document the prevalence rates of a list of unintended symptoms experienced and attributed to DAM by patients. To assess symptom complaints and other data, staff administered a six-page self-report questionnaire. The patients ascribed numerous symptoms to DAM, with the best-known being the most frequently reported (e.g. skin itching, sweating, constipation). Among potentially more problematic complaints ranged irregular menses, cognitive deficits, muscle twitches, labored breathing, pains in the cardiac region, and temporary paralysis of limbs. In the absence of a control group, however, these may also be due to other factors, such as expectation, co-medication, concomitant substance use or co-morbidity. This pilot study emphasizes the necessity of rigorous assessment of the true rates, types, severity and preventability of such complications, especially given the current efforts to establish heroin maintenance as an optional treatment for heroin dependence.

Dyspnea is the unpleasant awareness of breathing while healthy persons will hardly sense their own breath at rest. Dyspnea is comparable to pain because both caution the organism that will activate protective mechanisms to avoid further damage. Dyspnea results from central nervous processing of respiratory feed back signals. Feed back from respiratory muscles, the chest wall, the airways and the lung reach the brain while partial pressure of oxygen and carbon dioxide is continuously monitored and arterial blood gases are permanently stabilized. Sensation of breathlessness depends on its origin. Main qualities of dyspnea include air hunger during hypercapnia, laboured breathing during increased minute ventilation and chest tightness in asthma. During chronic dyspnea, respiratory control aims for a new breathing pattern that will ease breathlessness. Since respiratory control includes both autonomic regulation and cortical modulation of breathing, voluntarily guided respiration can be employed to influence other autonomic regulated systems and pain perception.

Continuous peripheral nerve blockade is often used for the management of postoperative pain, even in ambulatory patients. The reported incidence of infectious complications after continuous nerve blockade is low. We report a case of Staphylococcus aureus sepsis after total shoulder arthroplasty in a patient who presented to her surgeon 8 days postoperatively with lethargy and labored breathing. Preoperatively, the patient had received a continuous interscalene block for analgesia that was associated with a neck hematoma. After readmission, exploratory laparotomy, and extensive hospital stay, the patient was discharged to an extended care facility in good condition.
