Prevalence of pressure sores in a community sample of spinal injury patients

Objectives: To estimate the point prevalence of pressure sores in a community sample of spinal cord injured patients who were followed up by a spinal injuries unit and to evaluate whether self-management strategies were associated with decreased risk of pressure sores.

Setting: A regional spinal injuries unit, UK.

Design: Postal questionnaire survey. Main outcome measure: Presence of pressure sores.

Subjects: All patients who were being followed up on a regular basis by the unit.

Results: Out of 760, 520 replied to the questionnaire; 472 were eligible for analysis. Point prevalence of pressure sores was 23% (99). Failure to inspect the skin daily for pressure damage was associated with decreased prevalence of pressure sores (odds ratio (OR) 0.5; 95% confidence interval (CI) 0.2–0.83). Those who inspected their skin daily, however, had a higher proportion of stage I pressure sores, but this was not statistically significant. Smoking (OR 1.8; 95% CI 1–3.3) and pre-existing medical problems (OR 1.8; 95% CI 1–3) were associated with increased prevalence of pressure sores. Regular lifting of weight at least once in an hour while seated, age, gender, neurological level, employment status, living alone and faecal and urinary incontinence were not significant predictors of pressure sores.

Conclusions: Nearly one-quarter of participants had pressure sores at the time of the survey. Periodic weight lifts and daily inspection of skin for pressure damage were not associated with decreased prevalence of pressure sores in this sample. However, those who inspected skin daily tended to detect pressure damage early.

Management of acute overdose or withdrawal state in intrathecal baclofen therapy

STUDY DESIGN

Individuals who are treated with intrathecal Baclofen (ITB) pump delivery system for intractable spasticity can suffer from severe morbidity as a result of acute overdose or withdrawal of ITB, which can also be life threatening. Current literature has a number of single case studies with different approaches to the management in such states.

OBJECTIVES

The aim of this article is to consolidate available evidence and develop treatment pathways for acute ITB overdose and withdrawal states.

METHODS

We searched MEDLINE, EMBASE, CINAHL and the Cochrane Library databases using the keywords 'intrathecal', 'baclofen', 'withdrawal', 'overdose' to identify studies (published up to December 2010) that focused on presentation or treatment of acute overdose and withdrawal state in ITB therapy. Only original articles in English involving adult population were included.

RESULTS

Initial search revealed 130 articles. After reading the abstract, 13 studies on ITB overdose and 23 studies on ITB withdrawal were deemed suitable for inclusion. All studies were either single-case studies or case series.

CONCLUSION

Acute ITB overdose is managed with immediate cessation of baclofen delivery through the system, reducing the baclofen load by cerebrospinal fluid aspiration and by providing supportive treatment in an intensive care setting. There is no specific antidote for reversing overdose symptoms. Acute ITB withdrawal is managed by restoring the delivery of ITB, providing supportive care in an intensive care setting and using drugs like low dose propofol or benzodiazepines in selected cases. Early involvement of ITB physicians is strongly recommended.
