Insights
This study analyzed 50 subarachnoid hemorrhage (SAH) patients, finding 76% good outcomes despite diagnostic delays. Improvements in surgical techniques have ameliorated results compared to past series.
Area of Science:
- Neurosurgery
- Neurology
- Critical Care Medicine
Background:
- Subarachnoid hemorrhage (SAH) is a critical neurological emergency.
- Delayed diagnosis and treatment significantly impact patient outcomes.
- UNICAMP treated 50 SAH patients between 1988 and 1992.
Purpose of the Study:
- To analyze the outcomes of SAH patients treated at UNICAMP.
- To evaluate the impact of diagnostic and treatment delays on SAH prognosis.
- To compare current results with historical data from the same institution.
Main Methods:
- Retrospective analysis of 50 SAH patient records.
- Data collected on patient demographics, Hunt & Hess grades, and treatment timelines.
- Comparison with historical SAH series since 1956.
Main Results:
- Predominantly male patients (66.6%) with an average age of 47 years.
- High proportion of patients (74%) admitted more than 24 hours post-bleeding.
- Overall good results in 76% of cases, with 8% mortality post-surgery.
Conclusions:
- Despite significant delays in admission and diagnosis, overall SAH outcomes are comparable to literature standards.
- Technical improvements have led to better results than historical series.
- Faster management of SAH is crucial for improving patient survival and reducing morbidity.
Abstract:
A retrospective analysis of 50 patients who suffered subarachnoid hemorrhage (SAH) treated at UNICAMP between April 1988 and March 1992 is made, distributed as 34% in Hunt & Hess grade I, 38% in grade II, 16% in grade III, and 12% in grade IV. Males were predominant (66.6%), and patients age varied around 47 +/- 12.13 years old. Only 13 patients (26%) were admitted within the first 24 hours after bleeding, with an overall average of 20.45 days of delay. From all cases only one had a rebleeding, survived and was submitted to surgery. Four patients died after surgery (8%). Timing of operation and prognostic chances were available, being 27.30 days after SAH for Hunt & Hess group I. It is analyzed also the timing for diagnosis-which responded for the most delay, and treatment for the other groups, and a historical comparison with previous series since year 1956 of the same Hospital were documented. Good results were observed in 38 cases (76%). The overall results in terms of mortality and morbidity is, in comparison, in accordance with the literature, and is ameliorated from the past series due to technical improvement, despite worsen difficulties in managing admittance, diagnosis and treatment faster, which is required to deal with the disease.
