Abstract

- Traumatic brain injury (TBI) is a major cause of death and disability. Intracranial secondary insults (e.g. intracranial haematoma, brain oedema) and systemic secondary insults (e.g. hypotension, hypoxaemia, hyperthermia) lead to secondary brain injury and affect outcome adversely. In order to minimise secondary insults and to improve outcome in TBI-patients, a secondary insult program and standardised neurointensive care (NIC) was implemented. The aim of this thesis was to describe patient outcome and to explore the occurrence and prognostic value of secondary insults after the implementation.Favourable outcome was achieved in 79% and 6% died of the 154 adult TBI patients treated in the NIC unit 1996-97. In an earlier patient series from the department, 48% made a favourable outcome and 31% died. Hence, the outcome seems to have improved when NIC was standardised and dedicated to avoiding secondary insults. Secondary insults counted manually from hourly recordings on surveillance charts did not hold any independent prognostic information. When utilising a computerised system, which enables minute-by-minute data collection, the proportion of monitoring time with systolic blood pressure > 160 mm Hg decreased the odds of favourable outcome independent of admission variables (odds ratio 0.66). Hyperthermia was related to unfavourable outcome. Hypertension was correlated to hyperthermia and may be a part of a hyperdynamic state aggravating brain oedema. Increased proportion of monitoring time with cerebral perfusion pressure (CPP) < 60 mm Hg increased the odds of favourable outcome (odds ratio 1.59) in patients treated according to an intracranial pressure (ICP)-oriented protocol (Uppsala). In patients given a CPP-oriented treatment (Edinburgh), CPP <60 mm Hg was coupled to an unfavourable outcome. It was shown that pressure passive patients seem to benefit from an ICP-oriented protocol and pressure active patients from a CPP-oriented protocol. The overall outcome would improve if patients were given a treatment fit for their condition.
