Acute pain management services have progressed, albeit insufficiently in Canadian academic hospitals

PURPOSE: Acute pain management services (APMS) evolved in response to the desire for improved management of postoperative pain. The management of postoperative pain received formal support from international organizations over the past decade and by 1993 half of the Canadian university-affiliated teaching hospitals had implemented an APMS. The purpose of this survey was to describe APMSs in Canadian academic institutions, with specific emphasis on postoperative analgesics, new analgesic methods, training and research. METHODS: Between June 2000 and January 2001, 62 Canadian hospitals affiliated with the 16 Canadian university anesthesiology departments were sent a postal questionnaire. RESULTS: Fifty of the 62 respondents returned a completed questionnaire representing a response rate of 81%. Eighty percent of the hospitals surveyed had at least 200 beds, 90% (45) had implemented an APMS. Anesthesiology was primarily responsible in all 45 hospitals with an APMS. The results presented are based on the 45 centres with an APMS. CONCLUSION: Since the early 1990s the percent of Canadian academic hospitals with an APMS has increased from 53% to 92%. These figures are comparable to the United States. Greater collaboration from nursing and pharmacy, mandatory training for medical and nursing students and residents, and a standardized approach to continuous quality improvement remain necessary.     

Nutritional dwarfing: is it a consequence of disturbed psychosocial functioning?

Nutritional dwarfing refers to a condition in which maladaptive eating patterns play a primary role in poor linear growth and delayed pubertal development. The present controlled study assesses whether nutritionally dwarfed children and adolescents differ in their psychosocial adjustment from healthy children and adolescents of comparable height in ways that might account for their undernutrition. Children with nutritional dwarfing (n = 16) were compared by standardized questionnaires with a short-stature (ie, heights below the fifth percentile) control group composed of children and adolescents with constitutional growth delay and/or familial short stature (n = 31). Scores on a self-report screening questionnaire for eating disorders did not differentiate the groups. Moreover, the vast majority of nutritionally dwarfed patients expressed a desire to have a heavier physical appearance. Whereas the groups were generally similar in self-perceptions of domain-specific competencies and positive psychosocial adjustment, the parents of nutritionally dwarfed children reported that their children showed significantly fewer externalized behavior problems. These findings suggest the existence of an eating disturbance that compromises growth in childhood and/or adolescence which, unlike anorexia nervosa, is not associated with evidence of psychopathology.     

Noncardiac surgery in long-term implantable left ventricular assist-device recipients.

OBJECTIVE: The authors describe their experience with left ventricular assist-device (LVAD) recipients undergoing noncardiac surgery and delineate surgical, anesthetic, and logistic factors important in the successful intraoperative management of these patients. SUMMARY BACKGROUND DATA: Left ventricular assist-devices have become part of the armamentarium in the treatment of end-stage heart failure. As the numbers of patients chronically supported with long-term implantable devices grows, general surgical problems that are commonly seen in other hospitalized patients are becoming manifest. Of particular interest is the intraoperative management of patients undergoing elective noncardiac surgical procedures. METHODS: The anesthesia records and clinical charts were reviewed for eight ventricular assist-device recipients undergoing general surgical procedures between August 1, 1990 and August 31, 1994. RESULTS: A total of 12 procedures were performed in 6 men and 2 women averaging 52.7 years of age. Mean time elapsed from device implantation to operation was 68 +/- 35 days. Conventional inhalational and intravenous anesthetic techniques were well tolerated in these patients undergoing diverse surgical procedures. No perioperative mortality was observed. Five of eight patients went on to successful cardiac transplantation. CONCLUSIONS: Hemodynamic recovery after LVAD insertion has defined a new group of patients who develop noncardiac surgical problems often seen in other critically ill patients. Recognition of the unique potential problems that the LVAD recipient may encounter in the perioperative period--in particular patient positioning, device limitations, and fluid and inotropic management--will ensure an optimal surgical outcome for LVAD recipients undergoing noncardiac surgery.     

Everyday memory after unilateral temporal lobectomy or amygdalo-hippocampectomy.

Patients who had undergone unilateral temporal lobe surgery (right or left temporal lobectomy or amygdalo-hippocampectomy) for intractable temporal lobe epilepsy, and normal control subjects, completed two questionnaires about everyday memory, the Subjective Memory Questionnaire (SMQ) and the Everyday Memory Questionnaire (EMQ). Relatives/close friends completed suitably adapted versions of these questionnaires about the patient. Patients who had undergone right and left temporal lobectomy rated themselves, and were rated by relatives/friends as having worse memories than controls on both the SMQ and EMQ. Individual items on both questionnaires differentiated between the memory abilities of the five groups. Age at surgery was correlated with one measure of everyday memory for the right temporal lobectomy group, and seizure frequency was correlated with memory performance for the amygdalo-hippocampectomy groups. Issues concerning validity and accuracy of rating memory lapses are discussed.     

Incidence of fetal chromosome abnormalities in insulin dependent diabetic women.

In order to screen for fetal neural tube defects and chromosome abnormalities, amniocentesis was carried out in 334 women with insulin-dependent diabetes mellitus (IDDM) between 1979 and 1987. Two cases (0.6%; 95% confidence limits 0.1-2.2%) of fetal chromosome abnormality were found: one case of Klinefelter's syndrome and one case of de novo translocation. This is comparable to the overall incidence of chromosome abnormality found at birth and is also comparable to the incidence of fetal chromosome abnormality (1.0%) found by amniocentesis at our Department in a group of 2,264 young non-diabetic women with little risk of contracting genetic disorders. The results suggest that maternal IDDM does not increase the risk of fetal chromosome abnormality and consequently screening by amniocentesis for chromosome abnormalities among diabetic women does not seem to be indicated.
