- ItemSomente MetadadadosAnalysis of Risk Factors for Extubation Failure in Subjects Submitted to Non-Emergency Elective Intracranial Surgery(Daedalus Enterprises Inc, 2012-12-01) Vidotto, Milena Carlos [UNIFESP]; Sogame, Luciana Carrupt Machado [UNIFESP]; Gazzotti, Mariana Rodrigues [UNIFESP]; Prandini, Mirto Nelson [UNIFESP]; Jardim, Jose Roberto [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Escola Super Ciencias Santa Casa Misericordia VitBACKGROUND: Extubation failure is defined as the re-institution of respiratory support ranging from 24 to 72 hours following scheduled extubation and occurs in 2% to 25% of extubated patients. the aim of this study was to determine clinical and surgical risk factors that may predict extubation failure in patients submitted to non-emergency intracranial surgery. METHODS: This was a prospective observational cohort study. the study was carried out on 317 subjects submitted to non-emergency intracranial surgery for tumors, aneurysms, and arteriovenous malformation. Preoperative assessment was performed and subjects were followed up for the determination of extubation failure until either discharge from hospital or death. RESULTS: Twenty-six (8.2%) of the 317 subjects experienced extubation failure following surgery. the following variables were considered for the multivariate analysis: level of consciousness at the time of extubation, duration of mechanical ventilation prior to extubation, sex and the use of intraoperative mannitol. the multivariate analysis determined that the most important variable for extubation failure was the level of consciousness at the time of extubation (P = .001), followed by female sex, which also showed to be significant (P = .006). CONCLUSIONS: Lower level of consciousness (GCS 8T-10T) and female sex were considered risk factors for extubation failure in subjects submitted to elective intracranial surgery.
- ItemAcesso aberto (Open Access)Dor pós-operatória em craniotomia(Escola de Enfermagem de Ribeirão Preto / Universidade de São Paulo, 2005-08-01) Peón, Andréa Ungaro; Diccini, Solange [UNIFESP]; Hospital Israelita Albert Einstein; Universidade Federal de São Paulo (UNIFESP)In the postoperative period, 47% to 75% of the patients report some degree of pain. This study aimed to evaluate pain in the pre and postoperative period of patients submitted to craniotomy. This prospective research was carried out at the neurosurgery unit of a large Brazilian hospital. For a quantitative evaluation of pain, the verbal numeric 0 - 10 rating scale was used. Forty patients with a mean age of 36 years were evaluated. In the preoperative period, 34 (85%) patients indicated headache as the main cause of pain. In the postoperative period, 37 (93%) patients complained of pain while three (7%) reported absence of pain. Pain peaks were observed on the 2nd postoperative day, when 12 (32%) of the patients reported severe pain and 10 (27%) moderate pain. Absence of severe pain occurred after the 8th postoperative day. It was concluded that protocols of analgesia in craniotomy are needed, such as training nurses to better evaluate and handle pain.
- ItemAcesso aberto (Open Access)The far-lateral craniotomy: tips and tricks(Academia Brasileira de Neurologia - ABNEURO, 2014-09-01) Chaddad Neto, Feres Eduardo Aparecido [UNIFESP]; Doria-netto, Hugo Leonardo; Campos Filho, José Maria De; Reghin Neto, Mateus; Rothon Jr, Albert L; Oliveira, Evandro De; Universidade Federal de São Paulo (UNIFESP); Hospital Real e Benemérita Sociedade Portuguesa de Beneficência Instituto de Ciências Neurológicas Laboratório de Microcirurgia; Departamento de Neurocirurgia Vascular; Hospital Brigadeiro Departamento de Neurocirurgia Vascular; University of Florida Department of Neurosurgery; Universidade Estadual de Campinas (UNICAMP)This article intends to describe in a didactical and practical manner the suboccipital far-lateral craniotomy. This is then basically a descriptive text, divided according to the main stages involved in this procedure, and that describes with details how the authors currently perform this craniotomy.
- ItemAcesso aberto (Open Access)Orbitozygomatic craniotomy in three pieces: tips and tricks(Assoc Arquivos Neuro- Psiquiatria, 2016) Chaddad-Neto, Feres [UNIFESP]; Doria-Netto, Hugo Leonardo [UNIFESP]; Campos-Filho, Jose Maria [UNIFESP]; Reghin-Neto, Mateus; Silva-Costa, Marcos Devanir [UNIFESP]; Oliveira, EvandroObjective: Didactically describe the orbitozygomatic craniotomy made in three pieces. Method: This approach was performed, from 2002 to 2011, in 49 patients admitted at Beneficencia Portuguesa of Sao Paulo Hospital. Results: Twenty-seven patients had vascular lesions and twenty-two suffered for intracranial skull base tumors. The vascular lesions varied from cavernous angiomas inside the mesencephalum, high bifurcation basilar tip aneurysms, superior cerebellar arteries aneurysms and arteriovenous malformations in the interpeduncular cistern. Skull base tumors as meningiomas, interpeduncular hamartomas and third ventricle floor gliomas were among the neoplastic lesions approached. We had no permanent injuries and minimal transient complications had occurred. Conclusion: It is a descriptive text, organized in the sequence of the main stages in which such a craniotomy is performed, describing in details the technique in which this group of evolutionarily authors came to accomplish the task.
- ItemAcesso aberto (Open Access)Pretemporal craniotomy(Academia Brasileira de Neurologia - ABNEURO, 2014-02-01) Chaddad Neto, Feres Eduardo Aparecido [UNIFESP]; Dória-netto, Hugo Leonardo; Campos Filho, José Maria; Reghin Neto, Mateus; Oliveira, Evandro; Universidade Federal de São Paulo (UNIFESP); Instituto de Ciências Neurológicas; Hospital Beneficência Portuguesa de São Paulo; Universidade Estadual de Campinas (UNICAMP); Hospital Beneficência Portuguesa Instituto de Ciências NeurológicasThis paper aims to describe the performance of the pretemporal craniotomy performed didactically from 2002 to 2012 in eighty patients. It is therefore a fundamentally descriptive text, organized in the sequence of the main stages in which such a craniotomy is performed, and describing in detail the technique with which this group of evolutionarily authors came to accomplish the task.
- ItemSomente MetadadadosPulmonary function and thoraco-abdominal configuration after elective craniotomy(Lippincott Williams & Wilkins, 2008-03-01) Franceschini, Juliana [UNIFESP]; Sogame, Luciana Carrupt Machado; Gazzotti, Mariana Rodrigues [UNIFESP]; Vidotto, Milena Carlos [UNIFESP]; Jardim, Jose Roberto [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); EMESCAMBackground and Purpose: The development of pathophysiologic pulmonary alterations are observed after thoracic and abdominal surgeries. The purpose of this article is to report the alterations in the thoracoabdominal configuration and ventilometric parameters that occur during the postoperative period after elective craniotomy.Subjects: Forty-seven patients submitted to craniotomy owing to the presence of an aneurysm or tumor, under general anesthesia were analyzed.Methods: Tidal volume (TV), respiratory rate, and diaphragmatic index were measured from the preoperative period to the fourth postoperative day and pH, PaCO(2), PaO(2), and SaO(2) to the second postoperative day.Results: We observed a decrease in TV, an increase in respiratory rate, increased alveolar ventilation, and a change in the respiratory pattern from predominantly abdominal to predominantly thoracic respiration.Conclusions: A decrease in the diaphragmatic index, and a reduction in abdominal motion, associated to a lower TV, is suggestive that the lower parts of the lungs were less ventilated than the higher ones.
- ItemSomente MetadadadosVital capacity reduction in postoperative of elective craniotomy(Revista De Neurologia, 2008-08-01) Gazzotti, Mariana Rodrigues [UNIFESP]; Vidotto, Milena Carlos [UNIFESP]; Sogame, Luciana Carrupt Machado [UNIFESP]; Hayashi, Lucas Yutaka; Jardim, José Roberto [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); EMESCAMAims. To assess the vital capacity (VC), tidal volume, minute volume and respiratory rate during the first four postoperative days of elective craniotomy and how they are correlated with smoking , associated diseases and respiratory symptoms. Patients and methods. Ninety-four patients were initially evaluated for elective craniotomy and they were included in this study only if they presented normal consciousness level and spontaneous breathing at the first postoperative. The preoperative and postoperative evaluations comprised physical examination and ventilometry up to the fourth postoperative. The repeated measures analysis of variance was used to the ventilation measurements. The significance level adopted for all the statistical tests was p = 0.05. Results. Sixty-two patients were included in this study. There was a 20% fall in the VC from the first to the third postoperative (p = 0.001). Patients with systemic arterial hypertension presented in the preoperative period a lower mean VC (2.59 L) than the patients without (3.28 L) (p = 0.045). Smokers presented a lower mean VC (2.65 and 1.95 L) than the nonsmokers (3.13 and 2.43 L), both in the preoperative and in the postoperative, but with no statistic significance (p = 0.090). Conclusion. After elective craniotomy, there is a significant decrease in VC immediately after surgery, improving gradually thereafter; there was no different in VC between the smoking and nonsmoking patients in the pre- and postoperative as well.
