Analysis of the stay and morbidity and mortality rates in a unit for neurocritical patients following surgery for a brain tumour
AIM. To evaluate the association between the pre- and post-operative variables with stays in hospital lasting more than one day and the morbidity and mortality rates of patients undergoing surgery for a brain tumour during their stay in a neurocritical intensive care unit (NCU).
PATIENTS AND METHODS. The retrospective study, over a period of three years (2010-2012), involving a cohort of 317 patients who consecutively underwent surgical interventions due to brain tumours performed by different neurosurgeons and were hospitalised in the NCU.
RESULTS. A total of 21.5% (n = 68) of the patients were hospitalised for more than one day (group L), and 78.5% (n = 249) stayed for one day or less (group S). The univariable association of the pre- and post-operative risks with the length of stay was evaluated. There were no significant differences between groups L and S in terms of the demographic data, the physical status according to the classification of the American Society of Anesthesiologists (ASA), the pathological features or the radiological tumour severity index. Tracheal intubation was required in 42.6% (n = 29) of the patients in group L at some time during the post-operative period. Of the patients in group L, 19.1% (n = 13) had systemic and regional complications simultaneously.
