Introduction: The subarachnoid hemorrhage spontaneous (SAH) is an intracraneal
hemorrhage caused by the break of a cerebral vessel. It is not one of the most common
strokes, but it is needed to evaluate the prognosis as soon as possible, because of the
younger population affected and the greater functional aftereffects. Knowing the
prognosis allows informing the patients and relatives properly, and taking better
medical decisions.
Objective: Use a predictive model of early mortality, defined as the one ocurred within
the firts 30 days, developed by R. Núñez en his Doctoral Thesis at the Univesity of
Murcia.
Materials and methods: An observational, retrospective, single-center study was carried
out in patients admitted with SAH diagnosis throughout 2022, in the Intensive Care Unit
of the Hospital General Universitario Dr. Balmis de Alicante.
The prognostic score was calculated and univariate analysis was stratified by mortality
at 30 days of different sociodemographic variables, comorbidity, analytical, radiological,
treatment and complications.
Results: A total of 56 patients made up the study sample. Seven of the total cases died,
the actual mortality was 12.5%. The prognostic score calculation gave a value of 15.7%
± 21.8. There was no statistically significant association between actual and predicted
mortality (p-value 0.137). The median age was 59 (49-70), in those who died was 61 (49-
70) (p-value 0.941). 57% of the patients were women, 71 % of them in the deceased
group (p-value 0.686). 29% of the total consumed tobacco (p-value 1,000). The
prevalence of HT in the deceased group was 43% (p-value 0.669). At admission severe
coma (GCS < 9) measured by the Glasgow Comma Scale was observable in 30% (p-value
0.012). In the group of deceased patients: all had a grade IV on the Fisher scale (FS) (pvalue
0.027) and 3 patients (43%) were admitted with a grade V on the Hunt-Hess scale
(H-H) (p-value 0.114). 38 patients received ventilatory support (69%), including all the
deceased (p-value 0.084). In the same group, 43% had endocranial hypertension (HEC)
(p-value 0.074). 24 patients were treated with external ventricular shunt (EVD), 86% of
the deceased group (p-value 0,035). 25% developed delayed cerebral ischemia (DCI) (pvalue
0.35). The median natremia in the deceased group was 153 (148-156) (p-value
0.005). The main treatment was coils (89%), including those who died (87%). 14% of
patients presented a perimesencephalic pattern.
Conclusions: The actual mortality was lower than that observed in the literature. When
related to predicted mortality, there was no association. Of the variables selected,
hypernatremia, EVD, GCS and FS grade were associated with 30-day mortality. Although
more women were affected, no gender association was observed.
