Nonspecific behaviors as early indications of cerebral vasospasm.

This study investigated nonspecific behaviors as early indications of vasospasm following subarachnoid hemorrhage. Although symptoms of vasospasm (e.g., lowered level of consciousness, focal deficits such as hemiplegia or aphasia), are well recognized, the significance of early appearance of nonspecific symptoms such as restlessness, unusual behaviors, and impulsive behavior has not been investigated in detail. The study design included descriptive quantitative elements and a small qualitative component. Nonspecific behaviors were recorded, and the prevalence of those behaviors in individuals developing vasospasm was noted. Of 60 participants, 31 developed vasospasm; 24 of the 31 initially presented with nonspecific behaviors (p < .0001). Early detection of cerebral vasospasm allows prompt intervention and treatment, with the goal of preventing further ischemia or infarction.

Analysis of nursing assessments in a cohort patients with ruptured cerebral aneurysms.

Patients admitted with subarachnoid hemorrhage are monitored for symptoms of vasospasm. A prospective study was designed to compare two monitoring instruments: a standard neurological tool (SNR) and the National Institutes of Health Stroke Scale (NIHSS). The two assessment tools were compared to evaluate their concordance and to identify areas where efficiency in recording assessments might be improved. We found no statistical difference between the two tools in detecting symptomatic cerebral vasospasm. Substantial discrepancies in the documentation of observations were noted, particularly in the assessment of limb drift. Avoidance of these discrepancies may require further definition in the SNR tool. A qualitative component consisting of a review of the nurses' notes regarding neurological status in the patients' charts was conducted. It was demonstrated that nurses commonly document information in the progress notes that is already captured in the SNR. Further education of nurses in the use of assessment tools is therefore recommended to avoid redundancies and increase efficiency in recording clinical observations.

Lumbar discectomy: developing and implementing a day surgery protocol.

In some centres, patients who require a lumbar discectomy are successfully discharged the day of surgery. With the ongoing pressure to provide safe care for patients within certain bed limitations, this option was considered. Using a continuous quality improvement method, a prospective review of patients undergoing a single-level lumbar discectomy was monitored. Based on pre-set criteria, patients were included or excluded in the day surgery protocol and both groups were monitored. A large component of nursing education was provided for all patients, and will be highlighted. Data retrieved for both groups included demographics, length of operation, length in recovery room, length of hospital stay required, and the re-admission rate. There were 47 patients monitored over 11 months. Of the 34 patients entered in the protocol, seven required an overnight length of stay. The reasons for the extended length admission will be described. Of the 13 patients excluded from the protocol, one did not require an overnight stay. Following review of the data, the criteria for inclusion of patients into the protocol has been altered and patients can safely proceed with day surgery for lumbar discectomy.

Comparison of a standard neurological tool with a stroke scale for detecting symptomatic cerebral vasospasm.

The purpose of this study was to critically analyze the effectiveness of two tools used by nurses to assess neurological status of individuals at risk of developing cerebral vasospasm following aneurysmal subarachnoid hemorrhage due to aneurysm rupture. Early detection of vasospasm provides an opportunity for prompt treatment so that further ischemia or infarction can be prevented. We hypothesized that the National Institutes of Health Stroke Scale would detect symptomatic vasospasm earlier than the standard neurological record currently used in the practice setting of a tertiary care teaching hospital. Thirty participants were entered into the study, and a differential diagnostic process identified 15 with symptomatic vasospasm. Quantitative prospective and retrospective analysis showed that there was no statistical difference between the two scales in early detection of vasospasm. This finding may partially be explained by the clinical similarities between the vasospasm and nonvasospasm groups and by the challenges experienced by nurses in administering the stroke scale. Clinically relevant observations suggested the stroke scale was more effective in the assessment of focal symptoms. Qualitative content analysis of nursing notes also provided insight into clinical findings not captured on either scale regarding generalized changes such as restlessness, impulsiveness, and unusual behavior. This study demonstrates the need to develop a more appropriate tool for early detection of vasospasm.
