Consequences of Septicaemia
• Blood that doesn’t clot in a test tube (DIC)
• Fluid leaking out of blood vessels (shock)
• Clots happening in blood vessels (thrombosis)
• Not enough oxygen getting to tissues

• Fluid leaking out of blood vessels (brain

• Decreased blood flow to brain

Neurodevelopmental outcome

• 115 survivors from 1988-1990 cohort, assessed 1998-9
with 115 sex and age matched controls
• Cerebral Palsy 1, significant hearing loss 5
• Most survivors do not have gross neurological
deficits.
• Significant detriments of motor function, cognitive
ability and behavior were found in meningococcal
survivors.

Critical Illness and Amputation in
Meningococcal Septicaemia:
Is Life Worth Saving?
• Young people admitted to PICU with
meningococcal disease
• Nine participants who had undergone
amputations
• Standardized assessments made
• Funded by MRF

Quality of life after amputation.
Allport et al
• “Generally good”
• Not predicted by
degree of amputation
• Less good if learning
difficulties

Editor's Notes

  • #16 Degree of amputation, function, and quality of life for each participant (patients 1–9). Participants' results are ordered according limb loss degree (body maps). Functional ability was measured with the AMPS.6 The AMPS assesses the quality of performance of activities of daily living. Participants choose and perform 2 everyday tasks; results are adjusted for the difficulty of the task. Blue bars show motor scores (participants' ability to move themselves and the task objects). Purple bars show process or cognitive scores (how participants organize, sequence, and adapt to problems during the tasks). Quality of life was measured with Short Form-36 (>16 years of age) or the Child Health Questionnaire.7 Green bars show physical scores and blue bars mental/psychosocial summary scores. AMPS and Short Form-36/Child Health Questionnaire results are presented as z scores (number of SDs from the mean for age and gender).
