    Constipação intestinal em pacientes com tumores intracranianos
    (Escola de Enfermagem de Ribeirão Preto / Universidade de São Paulo, 2006-06-01) Torres, Analuiza Cândido [UNIFESP]; Diccini, Solange [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    The effort that occurs during the Valsalva maneuver provokes a raise in intracranial pressure and may decompensate patients with increased intracranial pressure. The aims of this study were to evaluate the incidence of intestinal constipation in the preoperative period of patients with intracranial tumors and establish a relationship between constipation and intracranial pressure decompensation. This study was performed at the neurosurgery unit of Hospital São Paulo, from August to October 2003, evaluating 37 patients. Preoperative time varied from 2 to 34 days (mean 12 days). During this period, 6 (16.2%) patients underwent constipation; all of them received dietary fiber and lactulose, 2 (33.3%) needed enema administration. All patients performed the Valsalva maneuver during defecation and none of them developed intracranial hypertension decompensation.

    Decompressive craniectomy: a meta-analysis of influences on intracranial pressure and cerebral perfusion pressure in the treatment of traumatic brain injury A review
    (Amer Assoc Neurological Surgeons, 2012-09-01) Bor-Seng-Shu, Edson; Figueiredo, Eberval G.; Amorim, Robson L. O.; Teixeira, Manoel Jacobsen; Valbuza, Juliana Spelta [UNIFESP]; Oliveira, Marcio Moyses de; Panerai, Ronney B.; Universidade de São Paulo (USP); Universidade Federal de São Paulo (UNIFESP); Maranhao Fed Univ; Univ Leicester
    Object. in recent years, the role of decompressive craniectomy for the treatment of traumatic brain injury (TB!) in patients with refractory intracranial hypertension has been the subject of several studies. the purpose of this review was to evaluate the contribution of decompressive craniectomy in reducing intracranial pressure (ICP) and increasing cerebral perfusion pressure (CPP) in these patients.Methods. Comprehensive literature searches were performed for articles related to the effects of decompressive craniectomy on ICP and CPP in patients with TBI. Inclusion criteria were as follows: 1) published manuscripts, 2) original articles of any study design except case reports, 3) patients with refractory elevated ICP due to traumatic brain swelling, 4) decompressive craniectomy as a type of intervention, and 5) availability of pre- and postoperative ICP and/or CPP data. Primary outcomes were ICP decrease and/or CPP increase for assessing the efficacy of decompressive craniectomy. the secondary outcome was the persistence of reduced ICP 24 and 48 hours after the operation.Results. Postoperative ICP values were significantly lower than preoperative values immediately after decompressive craniectomy (weighted mean difference [WMD] -17.59 mm Hg, 95% CI -23.45 to -11.73, p < 0.00001), 24 hours after (WMD -14.27 mm Hg, 95% Cl -24.13 to -4.41, p < 0.00001), and 48 hours after (WMD -12.69 mm Hg, 95% Cl -22.99 to -2.39, p < 0.0001). Postoperative CPP was significantly higher than preoperative values (WMD 7.37 mm Hg, 95% Cl 2.32 to 12.42, p < 0.0001).Conclusions. Decompressive craniectomy can effectively decrease ICP and increase CPP in patients with TBI and refractory elevated ICP. Further studies are necessary to define the group of patients that can benefit most from this procedure. (http://thejns.org/doi/abs/10.3171/2012.6.JNS101400)

    REGIONAL COOLING FOR REDUCING BRAIN TEMPERATURE AND INTRACRANIAL PRESSURE
    (Assoc Arquivos Neuro- Psiquiatria, 2009-06-01) Forte, Luis Vicente [UNIFESP]; Peluso, Cassio Morano [UNIFESP]; Prandini, Mirto Nelso [UNIFESP]; Godoy, Roberto; Rojas, Salomon Soriano Ordinola; Hosp Sao Joaquim; Hosp Meridional; Universidade Federal de São Paulo (UNIFESP)
    Objective: To evaluate the effectiveness of regional cooling for reducing brain temperature (BrTe) and intracranial pressure (ICP) in patients where conventional clinical treatment has failed. Method: Regional cooling was carried out using ice bags covering the area of the craniectomy (regional method) in 23 patients. The BrTe and ICP were determined using a fiber optic sensor. Thirteen patients (56.52%) were female. The ages ranged from 16 to 83 years (mean of 48.9). The mean APACHE II score was 25 points (11-35). The patients were submitted, on mean, to 61.7 hours (20-96) of regional cooling. Results: There was a significant reduction in mean BrTe (p<0.0001-from 37.1 degrees C to 35.2 degrees C) and mean ICP (p=0.0001-from 28 mmHg to 13 mmHg). Conclusion: Our results suggest that mild brain hypothermia induced by regional cooling was effective in the control of ICP in patients who had previously undergone decompressive craniectomy.
