Pediatric intensive care sedation: survey of fellowship training programs.

Children hospitalized in a pediatric intensive care unit are frequently distressed. The purpose of this study was to identify the patterns of use of sedative agents in pediatric critical care patients. A questionnaire survey was mailed to 45 directors of Pediatric Critical Care Fellowship Training Programs listed in Critical Care Medicine, January 1989. The response rate was 75.6% (34 questionnaires). The most commonly identified goals of sedation were reduced patient discomfort or distress and fewer unplanned extubations. The agents most frequently employed for this purpose were opioids (morphine or fentanyl), chloral hydrate, or benzodiazepines. Although conventional doses are used, opioids and benzodiazepines are often given hourly or by continuous infusion. Satisfaction with the efficacy and safety of commonly used opioids was greater (most common response "very satisfied") than for the benzodiazepines ("somewhat satisfied"). The physician's or nurse's clinical impression was reported to be the "most important" criterion for deciding when a patient required a dose of sedative; objective criteria were selected as less important. The majority of patients (65.7%) in the surveyed units were ideally "sedated to the point of no distress with as-needed medication." The majority of respondents (76.4%) identified efficacy as the major problem with sedation. Drug withdrawal was considered to be the major problem with sedative use by only a minority of respondents (6.9%). Although withdrawal is seen in 61.8% of units, it is generally treated when recognized, rather than prevented by routine tapering of sedation. Optimal sedation of pediatric intensive care unit patients is considered problematic, despite the use of frequent doses of many sedatives. Systematic investigation of pharmacodynamic response to these agents in the pediatric critical care population is indicated.

Anorexia nervosa in adolescent males: a review and case study.

The clinical presentation of anorexia nervosa among males is quite rare. This paper examines the personality and developmental issues of anorexia nervosa in adolescent males through a comprehensive review of the literature and a case presentation. In addition, this paper will demonstrate the application of the empirical literature in the development of a conceptual model to identify critical diagnostic and psychotherapeutic issues within the assessment of a clinically rare case, a male adolescent with anorexia nervosa.

Psychological development of technology-dependent children.

Reviewed the psychosocial and developmental challenges faced by technology-dependent children, their families, and their caregivers. Previous literature which has examined psychological outcome in children with repeated hospitalizations is presented. Psychosocial implications for programs addressing the needs of technology-dependent children are discussed.

A matched comparison of adjustment in children with cystic fibrosis and psychiatrically referred and nonreferred children.

Utilized the Child Assessment Schedule, a standardized clinical interview, to assess psychosocial adjustment in terms of DSM-III diagnoses. The criteria for a major DSM-III diagnosis were met by 58% of the children with cystic fibrosis compared to 23% for the nonreferred children and 77% for the psychiatrically referred children. Children with cystic fibrosis generally did not demonstrate more symptoms of psychological disturbance than nonreferred children. It was in terms of worries, poor self-image, and anxiety, that the children with cystic fibrosis demonstrated symptom levels comparable to that of psychiatrically referred children. Findings are discussed in terms of the specific risk of internalizing behavior problems for children with chronic illness.

Childhood chronic illness as a family stressor.

Investigated the impact of childhood chronic illness within a family context. We interviewed 30 mothers of 6- to 14-year-old children with asthma or diabetes and 30 mothers of healthy children of the same age and sex. Family functioning, extrafamilial social support available to mothers, and child life stress events were examined in relation to the children's psychological adjustment and illness events. The mothers of asthmatic children reported a greater number of internalizing behavior problems in their children, perceived their own social support as less adequate, and reported a greater number of stressful events. Regression analyses demonstrated that family functioning, maternal social support, and chronic illness were significantly related to the psychological adjustment of the child. The importance of family functioning and resources available to the family, such as social support, are discussed as protective influences in coping with childhood chronic illness.

Stress, coping, and family functioning in the psychological adjustment of mothers of children and adolescents with cystic fibrosis.

Assessed the role of illness parameters, demographic parameters, and hypothesized psychosocial/mediational processes in the psychological adjustment of 68 mothers of children and adolescents (7-17 years of age) with cystic fibrosis. Together the illness and demographic parameters accounted for only 13-15% of the variance in maternal adjustment. However, the hypothesized mediational processes accounted for 35-40% increment in the variance in maternal adjustment. More specifically, maternal adjustment was associated with lower levels of perceived daily stress, less use of palliative coping methods, and family functioning characterized by high levels of supportiveness.

Assessing distress in pediatric intensive care environments: the COMFORT scale.

Managing psychological distress is a central treatment goal in Pediatric Intensive Care Units (PICUs), with medical and psychological implications. However, there is no objective measure for assessing efficacy of pharmacologic and psychological interventions used to reduce distress. Development of the COMFORT scale is described, a nonintrusive measure for assessing distress in PICU patients. Eight dimensions were selected based upon a literature review and survey of PICU nurses. Interrater agreement and internal consistency were high. Criterion validity, assessed by comparison with concurrent global ratings of PICU nurses, was also high. Principal components analysis revealed 2 correlated factors, behavioral and physiologic, accounting for 84% of variance. An ecological-developmental model is presented for further study of children's distress and coping in the PICU.

Psychological adjustment of children with cystic fibrosis: the role of child cognitive processes and maternal adjustment.

Found 60% of children 7-12 years old with cystic fibrosis to have a parent-reported behavior problem and 62% met the criteria for a DSM-III diagnosis based on a structured clinical interview with the child. Mixed internal and external behavior problem patterns and diagnoses of anxiety and oppositional disorder were most frequent. Support was provided for the hypothesized psycho-social/mediational roles of child perception of self-worth and maternal anxiety in child adjustment. Together, the variables of the transactional stress and coping model accounted for 39 and 43% of the variance in mother-reported internalizing and externalizing behavior problems and for 68% of the variance in child-reported problems.

Optimal sedation of mechanically ventilated pediatric critical care patients.

OBJECTIVE: To derive a target range of optimal sedation for the COMFORT Scale and to prospectively test that target range against intensivist assessment of adequacy of sedation. DESIGN: Serial prospective agreement cohort studies. SETTING: Twelve-bed pediatric intensive care unit in an urban academic teaching hospital. PATIENTS: Eighty-five mechanically ventilated children (aged 0 to 102 months). INTERVENTIONS: Three serial prospective studies comparing simultaneous, independent ratings conducted by trained observers using an objective scale and intensive care physicians using global assessment. The initial study was designed to derive the target range. The second study was conducted to verify that target range in a second population. The third study was added to evaluate relative variability in methods used in the second study. MEASUREMENTS AND MAIN RESULTS: Adequacy of sedation using visual analog scale and descriptive ratings or the COMFORT Scale (a previously validated behaviorally anchored scale to rate eight behavioral or physiologic dimensions of distress). The first study comprised 100 observations. Groups of patients described by the intensivist as inadequately sedated, optimally sedated, and excessively sedated had different mean COMFORT scores (30.5 +/- 0.7 vs. 22.9 +/- 5.8 vs. 14.3 +/- 0.7, respectively, p < .05). The target range of optimal sedation was defined as COMFORT scores of 17 to 26. The second study verified the target range prospectively in a second group of 96 observations. The COMFORT score was strongly associated with the sedation adequacy rating by the intensivist (p < .001; r2 = .662). COMFORT scores accurately predicted the patient assignment to adequacy of sedation categories by the intensivist in 66.1% of observations. Discrepancy between physicians occurred in 38.5% of 16 paired physician ratings in the second study. In the third study, 120 observations comparing paired COMFORT scores to paired physician ratings of the same subjects demonstrated significantly less variability in COMFORT assessment of adequacy of sedation. COMFORT scores were similarly unbiased (1.1% vs. 0.22%) but more precise (8.0% vs. 16.7%) than intensivist ratings (p < .025). CONCLUSION: Adequacy of sedation is measured more consistently by observers using the COMFORT Scale than by intensivist global assessment.
