Purpose. There is a wide range of anesthetic practice in spine surgery with respect to anesthetic choice, blood conservation, and
monitoring. There is no ideal technique with respect to each of these choices. This study was designed to determine the usual
practice for members of the Society of Neurosurgical Anesthesia and Critical Care (SNACC), with regard to the use of anesthetic
technique, the type of monitoring used (and the person responsible for its application and interpretation), and the blood
conservation strategies most often utilized for the management of patients undergoing spinal surgery.
Methods. A total of 415 questionnaires were mailed to all current members of the SNACC. Of these, 85 (23%) were completed and returned.
Results. The majority of the respondents administer general anesthesia for lumbar laminectomy. Somatosensory evoked potential (SSEP)
monitoring is available at most of the institutions (94%) but only utilized in 75% of patients undergoing a Harrington rod
placement. Motor evoked potential monitoring is available at 50% of the institutions, but utilized 25% of the time for these
surgeries. The two most frequent blood conservation strategies utilized are intraoperative salvage and autologous donation.
Conclusion. The most frequent monitoring utilized for major spinal surgeries is SSEP. Autologous donation and intraoperative salvage
are the most frequent blood conservation methods utilized.

Surgery in spinal metastasis without spinal cord compression: indications and strategy related to the risk of recurrence 总被引:5,自引:0,他引:5
Surgery in patients presenting with vertebral metastasis without neural deficit is controversial. A series of 107 patients
(54 female, 53 male) were operated on at a mean age of 58. The metastasis was the first manifestation of the cancer in seven
cases. In 100 patients, the cancer had been diagnosed 30 months earlier (average). Vertebral pain was present in all cases,
with associated radicular pain in 43 cases. Pyramidal irritation without neural deficit was present in seven cases. The mean
preoperative Karnofsky index was 64.7%. The mean preoperative Tokuhashi score was 8.6. The surgical approach depended on the
topography of the metastasis. Ninety-three patients were dead at review, with a mean survival of 8 months. Seventeen patients
underwent further spinal surgery, for local recurrence in nine cases, and for another spinal localization in eight cases,
after a mean interval of 8 months. Recurrence occurred at the same level in all seven patients presenting with neural deficit
at recurrence. Among ten recurrences without neural deficit, two were observed at the same level and eight were observed on
another level. Surgery in vertebral metastasis without neural deficit results in substantial functional improvement, but does
not increase the duration of life. For kidney metastasis, total vertebrectomy must be performed because of the risk of recurrence.
For thyroid metastasis, total vertebrectomy is a good alternative to increase the efficacy of iodotherapy. In other cases,
for patients with good general status, surgery must be adapted to the location of the involvement.

Spinal hydatid cyst is a rare but serious condition. An 8-year-old boy presented with back pain, progressive weakness and numbness in both legs. Magnetic resonance imaging (MRI) of the lumbar region showed a cystic lesion with regular contour located in extradural space. There was cerebrospinal fluid- (CSF-) like signal intensity on T1- and T2-weighted images. The lesion had excessively compressed the dural sac and caudal roots, and expanded to the L3 and L4 neural foramina. The case was explored with L2, L3, L4 laminectomy and the hydatid cyst was removed totally. The clinical presentation, diagnosis and surgical treatment of this rare case of spinal hydatid disease is discussed, and all available cases of primary extradural hydatid cyst reported in the literature are presented. 相似文献

Extradural meningiomas account for approximately 7% of all spinal meningiomas and are most commonly located in the thoracic spine. Although rare, they should be included in the differential diagnosis of an extradural contrast-enhancing mass. Prognosis depends greatly on the extent of surgical resection. If considered safe, complete resection should be attempted to decrease the risk of recurrence. We report a case of spinal epidural meningioma diagnosed in an elderly woman complaining of right cervicobrachial pain of several years duration, associated with diffuse paresthesia and permanent numbness of her right index finger. The surgical removal of the tumor was incomplete because of the deep lateral extension of the lesion. 相似文献

Purpose
Surgery for spinal metastasis is often associated with significant morbidity. Despite a number of preoperative scoring systems/scales and identified variables that have been reported to predict complication risk, clinical studies that directly evaluate this issue using multivariate analysis are scarce. The goal of our study was to assess independent predictors of complication after surgery for spinal metastasis.Methods
We queried electronic medical records to identify a consecutive population of adult patients who underwent surgery for spinal metastasis for the period June 2005 through June 2011. Utilizing multivariate logistic regression, we assessed independent predictors of perioperative and postoperative adverse events.Results
A total of 106 patients were included in the final analysis. Overall complication rate was 21.7 %. Independent predictors for higher rates of complication were age greater than 40 years [40–65 years had odds ratio (OR) 1.91, 95 % confidence interval (CI) 1.02–16.78 and >65 years had OR 5.17, 95 % CI 1.54–29.81] and metastatic lesions involving three or more contiguous levels of the spine (OR 2.76, 95 % CI 1.09–9.61).Conclusions
Patients older than 40 years or patients who have metastatic lesions involving three or more contiguous vertebral levels appear to be at higher risk for complication. Patients older than 65 years have the greatest likelihood of complication.14.

Low-dose aspirin before spinal surgery: results of a survey among neurosurgeons in Germany 总被引:1,自引:0,他引:1
Marcus C. Korinth Joachim M. Gilsbach Martin R. Weinzierl 《European spine journal》2007,16(3):365-372
The main problem faced by the increasing numbers of patients presenting for spinal surgery are receiving concurrent medication
with low-dose aspirin, leading to dysfunctional circulating platelets. The contribution of low-dose aspirin to increased peri-operative
risk of bleeding and blood loss is a contentious issue with conflicting published results from different surgical groups.
Data from neurosurgical spine patients is sparse, but aspirin has been identified as an important risk factor in the development
of post-operative hematoma following intracranial surgery. We surveyed the opinions and working practices of the neurosurgical
facilities performing spinal operations in Germany regarding patients who present for elective spinal surgery. Identical questionnaires
were sent to 210 neurosurgical facilities and proffered five main questions: (1) the adherence of any policy of stopping aspirin
pre-operatively, (2) the personal risk assessment for patients with spinal surgery under low-dose aspirin medication, (3)
the preferred method of treatment for excessive bleeding in this context, (4) personal knowledge of hemorrhagic complications
in this group of patients, and (5) the characteristics of the neurosurgical units concerned. There were 145 (69.1%) responses
of which 142 (67.6%) were valid. Of the respondents, 114 (80.3%) had a (written) departmental policy for the discontinuation
of pre-operative aspirin treatment, 28 (19.7%) were unaware of such a policy. The mean time suggested for discontinuation
of aspirin pre-operatively was 6.9 days (range: 0–21 days), with seven respondents who perform the operations despite the
ongoing aspirin medication. Ninety-four respondents (66.2%) considered that patients taking low-dose aspirin were at increased
risk for excessive peri-operative hemorrhage or were indetermined (8.6%), and 73 (51.4%) reported having personal experience
of such problems. Ninety-two respondents (65.5%) would use special medical therapy, preferably Desmopressin alone or in combination
with other blood products or prohemostatic agents (46.1%), if hemorrhagic complications developed intra- or post-operatively.
The average number of spinal operations per year in each service was 607.9 (range: 40–1,500). Despite the existence of distinct
departmental policies concerning the discontinuation of low-dose aspirin pre-operatively in the majority of neurosurgical
facilities performing spinal operations, there is a wide range of the moment of this interruption with an average of 7 days.
Two-thirds of the respondents felt that aspirin was a risk factor for hemorrhagic complications associated with spinal procedures,
and more than half of the interviewees reported having personal experience of such problems. Finally, various medicamentous
methods of counteracting aspirin-induced platelet dysfunction and excessive bleeding in this context are elicited, discussed
and evaluated. 相似文献

P Johnstone 《Burns : journal of the International Society for Burn Injuries》1985,11(3):216-219
The nature of follow-up procedure practised by burn treatment units in the United Kingdom was investigated using a questionnaire sent to 30 units. Information from 23 units who replied indicated that all units consider that follow-up is essential and pressurized patients by a variety of means to attend. All units also recognized that medical, nursing and a variety of rehabilitation staff are required for follow-up care. There was a lesser involvement of social workers and a minimal involvement of psychiatric staff. All units obviously utilize a variety of clinics to follow patients after discharge from the burns unit. There appears to be no standard form of follow-up, units having made pragmatic arrangements to cover problems identified in clinical practice. 相似文献
