Ferric carboxymaltose for anemia in Crohn's disease patients at a tertiary center: A retrospective observational cohort study.

BACKGROUND: Although the gastrointestinal tract is the most affected by Crohn's disease (CD), the condition triggers other consequent manifestations, and iron deficiency anemia (IDA) is one of the most common. Intravenous (IV) iron replacement is currently available through several drugs, such as ferric hydroxide sucrose and ferric carboxymaltose (FCM). However, the clinical management of these conditions can be challenging. AIM: To elucidate the drug's effectiveness, the present study analyzed, through medical records, the clinical and epidemiological data of a cohort of patients with active CD who received IV FCM for the IDA treatment. METHODS: This retrospective observational study included 25 patients with active CD, severe anemia, and refractory to previous conventional treatments. Patients were evaluated two times: During the last treatment with ferric hydroxide sucrose and treatment with FCM. RESULTS: After treatment with FCM, parameters of IDA assessment significantly improved, serum hemoglobin (Hb) levels increased in 93% of patients (P < 0.0001), and in 44%, there was an increase of ≥ 2 g/dL in a single application. In addition, 86% of the patients showed an increase in serum iron (P < 0.0001) and ferritin (P = 0.0008) and 50% in transferrin saturation (P = 0.01). The serum iron levels at baseline showed a negative association with the ileal and colonic CD and use of biologics and a positive association with patients who developed CD later in life after the age of 40 (A3) and with a stenosing (B2) and fistulizing (B3) phenotype. The values of Hb and hematocrit after ferric hydroxide sucrose treatment remained similar to those found before treatment. CONCLUSION: This study demonstrated that FCM is an important therapeutic strategy for treating IDA in CD patients, achieving satisfactory results in refractory cases.

VOLUMETRIC CAPNOGRAPHY FOR RESPIRATORY MONITORING OF PATIENTS DURING ROUTINE COLONOSCOPY WITH ROOM-AIR AND CARBON DIOXIDE INSUFFLATION.

BACKGROUND: Capnography and carbon dioxide (CO2) insufflation during gastrointestinal endoscopy under sedation are associated with safety and comfort improvements, respectively. Capnography can provide early detection of apnea and hypoxemia, whereas CO2 insufflation causes lower periprocedural discomfort. This is the first study to report the application of volumetric capnography in colonoscopy. OBJECTIVE: This study aimed to evaluate the use of volumetric capnography with room air (RA) and CO2 insufflation during routine colonoscopy. METHODS: In this prospective cohort study, 101 patients who underwent routine colonoscopy under sedation with volumetric capnography monitoring were included. Insufflation with RA was used to distend the intestinal lumen in group 1 (n=51), while group 2 (n=50) used CO2 insufflation. The primary endpoints were episodes of hypoxia, alveolar hypoventilation, and end-tidal CO2 (EtCO2). The secondary endpoints were tidal volume per minute, consumption of sedation medications, and post-procedure pain using the Gloucester modified pain scale. RESULTS: The number of episodes of hypoxia (SpO2<90%) was similar between the groups: four episodes in Group 1 and two episodes in Group 2. The duration of hypoxia was significantly longer in group 2 (P=0.02). Hypoalveolar ventilation (EtCO2) occurred more frequently in Group 2 than in Group 1 (27 vs 18 episodes, P=0.05). Regarding EtCO2, Group 2 showed higher values in cecal evaluation (28.94±4.68 mmHg vs 26.65±6.12 mmHg, P=0.04). Regarding tidal volume per minute, Group 2 had significantly lower values at the cecal interval compared to Group 1 (2027.53±2818.89 vs 970.88±1840.25 L/min, P=0.009). No episodes of hypercapnia (EtCO2 > 60 mmHg) occurred during the study. There was no difference in the consumption of sedation medications between the groups. Immediately after colonoscopy, Group 2 reported significantly less pain than Group 1 (P=0.05). CONCLUSION: In our study, volumetric capnography during colonoscopy was feasible and effective for monitoring ventilatory parameters and detecting respiratory complications. CO2 insufflation was safe and associated with less pain immediately after colonoscopy.

RESUMO Contexto: A capnografia e a insuflação de gás carbônico (CO2) durante endoscopia digestiva sob sedação são associados à maior segurança e conforto do paciente, respectivamente. A capnografia pode detectar precocemente a apneia e hipoxemia, enquanto a insuflação de CO2 causa menor desconforto periprocedimento. Relatos da aplicação da capnografia volumétrica em colonoscopias são escassos. Objetivo: Avaliar o uso de capnograifa volumétrica durante colonoscopia diagnóstica com insuflação de ar comprimido e CO2. Métodos: Em estudo prospectivo de coorte, foram incluídos um total de 101 pacientes submetidos a colonoscopia diagnóstica sob sedação com monitoração respiratória por meio de capnografia volumétrica. Insuflação com ar comprimido foi usado para distender o lúmen intestinal no Grupo 1 (n=51), enquanto o Grupo 2 (n=50) utilizou CO2 para insuflação. Objetivos primários foram avaliar episódios de hipóxia, hipoventilação alveolar e CO2 expirado (EtCO2). Objetivos secundários foram avaliar o volume alveolar por minuto, consumo de sedativos e a dor pós-colonoscopia por meio da Escala de Dor Modificada de Gloucester. Resultados: O número de episódios de hipóxia (SpO2 <90%) foi semelhante entre os grupos: quatro episódios no Grupo 1 e dois episódios no Grupo 2. A duração da hipóxia foi significativamente maior no Grupo 2 (P=0,02). A hipoventilação alveolar (EtCO2 ≥25% do valor basal) ocorreu mais frequentemente no Grupo 2 quando comparado ao Grupo 1 (27 vs 18 episódios, P=0,05). Em relação ao EtCO2, o Grupo 2 apresentou valores maiores no momento de aferição cecal (28.94±4.68 vs 26.65±6.12 mmHg, P=0,04). Quanto ao volume alveolar por minuto, o Grupo 2 apresentou valores significativamente menores no momento de aferição cecal quando comparado ao Grupo 1 (2027.53±2818.89 vs 970.88±1840.25 L/min, P=0,009). Não houve ocorrência de hipercapnia durante o estudo (EtCO2 >60 mmHg). Não houve diferença em relação ao consumo de sedativos entre os dois grupos. Imediatamente após a colonoscopia, o Grupo 2 apresentou significativamente menos dor que o Grupo 1 (P=0,05). Conclusão: Em nosso estudo, a capnografia volumétrica durante colonoscopia foi factível e eficaz para monitorar parâmetros ventilatórios e detectar complicações respiratórias, e a insuflação com CO2 foi segura e associada a menor dor imediatamente pós-colonoscopia.

Pouchitis: insight into the pathogenesis and clinical aspects.

Ulcerative colitis (UC) is a chronic intestinal inflammatory disease and familial adenomatous polyposis (FAP) is an autosomal dominant inherited disease. Both diseases, despite being different, may require the same surgical procedure: proctocolectomy with ileal pouch-anal anastomosis (IPAA). The main complication after this procedure is pouch inflammation (pouchitis). This inflammatory complication can affect up to 60 percent of patients who receive IPAA for UC, and a very small percentage of the FAP patients. The purpose of this review was to determine the current molecular mechanisms in its pathogenesis and detail the risk factors involved in pouchitis, its diagnosis, and treatment.

Internal hernia through mesocolon defect after left laparoscopic colectomy / Hérnia interna pelo defeito mesocólico após colectomia esquerda laparoscópica

ABSTRACT Introduction: The development of internal hernias due to the mesocolon defect after laparoscopic colectomy is a rare complication with only 39 cases described. There are controversies whether the closure of the defect of the mesocolon after resection of the colon could prevent the development of this complication. Objective: To describe a case of intestinal obstruction due to internal hernia through the mesocolon defect after laparoscopic rectosigmoidectomy and to perform a literature review. Case report: A 59-year-old woman was hospitalized for laparoscopic rectosigmoidectomy due to an adenocarcinoma located in the rectosigmoid junction. She underwent a rectosigmoidectomy by laparoscopy, with an extracorporeal mechanical anastomosis, without closure of the mesocolon defect. In the fifth postoperative day the patient presented an intestinal obstruction due to an internal hernia through the mesocolon defect confirmed by computerized tomography. During the exploratory laparotomy approximately 120 cm jejunum was identified through the mesocolon defect. The reduction of herniated small bowel was done without the need of intestinal resection. The mesocolon defect was corrected by continuous suture. After the reoperation, the patient presented a favorable recovery being discharged on the fifth day. Conclusion: Intestinal obstruction due to internal hernia after laparoscopic rectosigmoidectomy is a rare postoperative complication that can be avoided by the adequate closure of the mesocolon defect.

RESUMO Introdução: O desenvolvimento de hérnias internas pelo defeito mesocólico após a realização de colectomia laparoscópica é uma complicação rara com apenas 39 casos descritos. Existem controvérsias se fechamento do defeito após a ressecção do cólon preveniria o desenvolvimento desta complicação. Objetivo: Descrever um caso de obstrução intestinal por hérnia interna pelo defeito mesocólico, após retossigmoidectomia laparoscópica e revisar a literatura relacionada ao tema. Relato do caso: Mulher, 59 anos foi internada para realizar ressecção cirúrgica de adenocarcinoma localizado na junção retossigmoideana. Foi submetida à retossigmoidectomia laparoscópica, com confecção de anastomose mecânica extracorpórea. O defeito mesocólico não foi corrigido no final do procedimento. No quinto dia de pós-operatório, a doente apresentou quadro de obstrução intestinal cuja tomografia computadorizada identificou presença de hérnia interna pelo defeito do mesocólon. Na laparotomia exploradora identificou-se que aproximadamente 120 cm de alças jejunais estavam herniadas através do defeito mesocólico. Realizou-se a redução do intestino delgado herniado sem necessidade de ressecção intestinal. O defeito foi corrigido por sutura contínua. Após a reoperação a doente apresentou evolução favorável recebendo alta no quinto dia. Conclusão: Obstrução intestinal após retossigmoidectomia laparoscópica consequente à formação de hérnia interna é complicação pós-operatória rara, com alta mortalidade, que pode ser evitada pelo fechamento criterioso do defeito do mesocólico.

Serum Levels of Infliximab and Anti-Infliximab Antibodies in Brazilian Patients with Crohn's Disease.

OBJECTIVES: The aim of this study was to evaluate the quantitative serum level of infliximab (IFX) as well as the detection of anti-infliximab antibodies (ATIs) in patients with Crohn's disease (CD). METHOD: Forty patients with CD under treatment at a tertiary center in southeastern Brazil were evaluated. Their use of infliximab was continuous and regular. We analyzed and compared the differences in the IFX and ATI levels between the patients with active CD (CDA) and those with CD in remission (CDR). RESULTS: There was no difference in the IFX level between the CDA and CDR groups (p>0.05). Eighty percent of all patients had IFX levels above the therapeutic concentration (6-10 µg/mL). Two (9%) of the 22 patients with active disease and four (22.2%) of the 18 patients in remission had undetectable levels of IFX. Four (66.6%) of the six patients with undetectable levels of IFX had positive ATI levels; three of these patients were in remission, and one had active disease. In addition, the other two patients with undetectable levels of IFX presented ATI levels close to positivity (2.7 and 2.8 AU/ml). None of the patients with therapeutic or supratherapeutic IFX levels had positive ATI levels. CONCLUSIONS: The undetectable levels of IFX correlated with the detection of ATIs, which was independent of disease activity. Immunogenicity was not the main factor for the loss of response to IFX in our study, and the majority of patients in both groups (CDA and CDR) had supratherapeutic levels of IFX.

VISCERAL FAT IS INCREASED IN INDIVIDUALS WITH CROHN'S DISEASE: A COMPARATIVE ANALYSIS WITH HEALTHY CONTROLS.

BACKGROUND: It is known that obesity is associated with a chronic inflammatory state, but few studies have evaluated visceral fat (VF) content and its role in individuals with Crohn's disease (CD). OBJETIVE: To compare the nutritional status, body composition and proportion of VF between CD individuals and healthy volunteers. METHODS: Cross-sectional study that enrolled individuals with Crohn's disease and healthy controls. The stratification according to nutritional status was carried out by means of BMI. The percentage of body fat percentage (%BF) and VF were estimated by means of DEXA. VF proportion was evaluated by means of the VF/BMI and VF/%BF ratios. RESULTS: A total of 78 individuals were included. The control group was comprised of 28 healthy subjects aged 35.39±10 years old (60.7% women); mean BMI=23.94±3.34 kg/m2; mean VF=511.82±448.68 g; mean CRP=0.81±1.78 ng/mL. The CD group was comprised of 50 patients; 11 (22%) were underweight (BMI=18.20±1.97 kg/ m2; %BF=24.46±10.01; VF=217.18±218.95 g; CRP=4.12±4.84 ng/mL); 18 (36%) presented normal weight (BMI=22.43±1.48 kg/m2; %BF=30.92±6.63; VF=542.00±425.47 g and CRP=4.40±1.78 ng/mL); 21 (42%) were overweight or obese (BMI=29.48±3.78 kg/m2; %BF=39.91±7.33; VF=1525.23±672.7 g and CRP=1.33±2.06 ng/mL). The VF/BMI ratio was higher in the CD group when compared to controls (32.41±24.63 vs 20.01±16.23 g per BMI point; P=0.02). Likewise, the VF/%BF was also higher in the CD group (35.21±23.33 vs 15.60±12.55 g per percentage point; P<0.001). CONCLUSION: Among individuals with Crohn's disease, BMI presents a direct correlation with visceral fat content. These results indicate the presence of an adiposopathy in Crohn's disease subjects, which is evidenced by a higher visceral fat.

RESUMO CONTEXTO: Sabe-se que a obesidade associa-se a um estado de inflamação crônica, mas faltam estudos que avaliem o conteúdo de gordura visceral em indivíduos com doença de Crohn. OBJETIVO: Comparar o estado nutricional, a composição corporal e a proporção de gordura visceral entre indivíduos com doença de Crohn (DC) e controles saudáveis (CS). MÉTODOS: Estudo transversal com doença de Crohn e controles saudáveis. O estado nutricional foi estratificado de acordo com o índice de massa corpórea (IMC). O percentual de gordura corporal (%GC) e a mensuração da gordura visceral foram avaliados por DEXA. A proporção de gordura visceral (GV) foi avaliada pelas relações entre GV/IMC e GV/%GC. RESULTADOS: Foram incluídos 78 indivíduos no estudo. O grupo CS foi constituído por 28 indivíduos saudáveis, com idade média de 35,39±10 anos; 60,7% mulheres; IMC=23,94±3,34 kg/m2; %GC=32,7±7,89; GV=511,82±448,68 g e PCR=0,81±1,78 ng/mL. O grupo DC foi composto por 50 indivíduos, destes, 11 (22%) desnutridos (IMC=18,20±1,97 kg/m2; %GC 24,46±10,01; GV=217,18±218,95 g; PCR=4,12±4,84 ng/mL); 18 (36%) eutróficos (IMC=22,43±1,48 kg/m2; %GC=30,92±6,63; GV=542,00±425,47 g e PCR=4,40±1,78 ng/mL); 21 (42%); sobrepeso/obesidade (IMC=29,48±3,78 kg/m2; %GC=39,91±7,33; GV=1525,23±672,76 g e PCR=1,33±2,06 ng/mL). A relação GV/IMC foi maior no grupo DC quando comparado aos do grupo CS (32,41±24,63 vs 20,01±16,23 gramas por ponto do IMC; P=0,02), assim como a relação GV/%GC que também foi maior no grupo DC (23,33±33,33 vs 12,55±2,37 gramas por ponto percentual; P<0,001). CONCLUSÃO: Entre os indivíduos com doença de Crohn, o IMC apresentou correlação direta com o conteúdo de gordura visceral. Esses resultados sinalizam a ocorrência de adiposopatia nos pacientes com doença de Crohn, com maior volume de tecido adiposo visceral.

Changes in serum levels of lipopolysaccharides and CD26 in patients with Crohn's disease.

BACKGROUND/AIMS: Lipopolysaccharide (LPS) is a molecule formed by lipids and polysaccharides and is the major cell wall component of gram-negative bacteria. High LPS levels are known to block CD26 expression by activating Toll-like receptor 4. The aim of this study was to correlate the serum levels of LPS and CD26 in Crohn's disease (CD) patients with serum levels of C-reactive protein (CRP), interleukins, CD activity index, and tumor necrosis factor-α (TNF-α). METHODS: Serum samples were collected from 27 individuals (10 with active CD, 10 with inactive CD, and 7 controls) and the levels of LPS, CD26, TNF-α, interleukin-1ß (IL-1ß), IL-6, IL-17, and CRP were determined by enzyme-linked immunosorbent assay. The levels of LPS and CD26 were then tested for correlation with TNF-α, IL-1ß, IL-6, IL-17, and CRP. RESULTS: Serum levels of LPS were significantly elevated in the active CD group (P=0.003). Levels of IL-1ß (P=0.002), IL-6 (P=0.003), and IL-17 (P<0.001) were lower in the CD groups. Serum TNF-α levels were increased in the active CD group. The CRP levels were elevated in the CD groups when compared to controls (P<0.001). The CD26 levels were lower in the CD groups than in the control group (P<0.001). Among the variables analyzed, there was a correlation between LPS and CRP (r=-0.53, P=0.016) in the CD groups. CONCLUSIONS: Individuals with CD exhibited higher serum levels of LPS varying from a 2- to 6-fold increase depending on disease activity, when compared with healthy controls. CD26 levels were lower in the CD groups. Both LPS and CD26 correlated with disease severity and serve as potential CD biomarkers.

Transcriptional and Molecular Pathways Activated in Mesenteric Adipose Tissue and Intestinal Mucosa of Crohn's Disease Patients.

Crohn's disease (CD) is a chronic inflammatory disorder, characterized by cytokine imbalance and transcription signaling pathways activation. In addition, the increase of mesenteric adipose tissue (MAT) near the affected intestinal area is a hallmark of CD. Therefore, we evaluated the transcription signaling pathways and cytokines expression in intestinal mucosa and MAT of active CD patients. Ten patients with ileocecal CD and eight with noninflammatory diseases were studied. The biopsies of intestinal mucosa and MAT were snap-frozen and protein expression was determined by immunoblotting. RNA levels were measured by qPCR. The pIkB/IkB ratio and TNFα level were significantly higher in intestinal mucosa of CD when compared to controls. However, STAT1 expression was similar between intestinal mucosa of CD and controls. Considering the MAT, the pIkB/IkB ratio was significantly lower and the anti-inflammatory cytokine IL10 was significantly higher in CD when compared to controls. Finally, the protein content of pSTAT1 was higher in MAT of CD compared to controls. These findings reinforce the predominance of the proinflammatory NF-kB pathway in CD intestinal mucosa. For the first time, we showed the activation of STAT1 pathway in MAT of CD patients, which may help to understand the physiopathology of this immune mediated disease.

Adenocarcinoma of the Right Colon in a Patient with Bloom Syndrome.

Introduction. Bloom syndrome (BS) is an inherited disorder due to mutation in BLM gene. The diagnosis of BS should be considered in patients with growth retardation of prenatal onset, a photosensitive rash in a butterfly distribution over the cheeks, and an increased risk of cancer at an early age. Clinical manifestations also include short stature, dolichocephaly, prominent ears, micrognathia, malar hypoplasia and a high-pitched voice, immunodeficiency, type II diabetes, and hypogonadism associated with male infertility and female subfertility. The aim of this report is to describe case of patient with BS who developed adenocarcinoma of the cecum, successfully treated by right colectomy. Case Report. A 40-year-old man underwent colonoscopy to investigate the cause of his diarrhea, weight loss, and anemia. The patient knew that he was a carrier of BS diagnosed at young age. The colonoscopy showed an expansive and vegetating mass with 5.5 cm in diameter, located within the ascending colon. Histopathological analysis of tissue fragments collected during colonoscopy confirmed the presence of tubular adenocarcinoma, and he was referred for an oncological right colectomy. The procedure was performed without complications, and the patient was discharged on the fifth postoperative day. Histopathological examination of the surgical specimen confirmed the presence of a grade II tubular adenocarcinoma (stage IIA). The patient is currently well five years after surgery, without clinical or endoscopic signs of relapse in a multidisciplinary approach for the monitoring of comorbidities related to BS. Conclusion. Despite the development of colorectal cancer to be, a possibility rarely described the present case shows the need for early screening for colorectal cancer in all patients affected by BS.

Influence of the peritoneal lavage with bupivacaine on the survival and resistance of colonic anastomoses performed under fecal peritonitis in rats.

PURPOSE: To evaluate the effects of peritoneal lavage with bupivacaine on survival and initial resistance of anastomosis on distal colon, performed under peritonitis or not. METHODS: Forty rats, weighing from 300 to 350 g (321.29 ± 11.3 1g), were randomly divided in four groups and underwent laparotomy and anastomosis on the distal colon six hours after induction of peritonitis by intraperitoneal injection of autologous fecal material or not. Group 1: No peritonitis and lavage with 3 ml NS; Group 2: No peritonitis and lavage with 8 mg.kg-1 (± 0.5 mL) of 0.5% bupivacaine added to 2.5 mL of NS; Group 3: Peritonitis and lavage with 3 ml NS; Group 4: Peritonitis and lavage with 8 mg.kg-1 (± 0.5 mL) of 0.5% bupivacaine added to 2.5 mL of NS. Necropsies were performed on the animals that died and the time of death was recorded. Surviving animals were submitted to euthanasia on the fifth post-operative day and Total Energy of Rupture biomechanical test (TER) was applied. RESULTS: Group 4 showed survival increase compared to Group 3, without statistical significance. Group 3 presented the smallest average TER, with statistical significance. CONCLUSION: Peritonitis increased mortality and influenced negatively the resistance of colic anastomosis in rats. Peritoneal lavage with bupivacaine increased anastomotic resistance.

Quality of life in patients with ileal pouch for ulcerative colitis / Qualidade de vida em portadores de reservatório ileal por retocolite ulcerativa

INTRODUCTION: proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the standard surgical procedure for the treatment of ulcerative colitis (UC) and is associated with the prospect of cure. Experience gained over the years has demonstrated the occurrence of a high number of complications as well as bowel disorders that can compromise quality of life (QoL). OBJECTIVE: evaluate QoL in patients with IPAA for ulcerative colitis. PATIENTS AND METHODS: the Inflammatory Bowel Disease Questionnaire (IBDQ) was used to assess QoL in patients with IPAA after its validation in Portuguese. RESULTS: thirty-one patients submitted to IPAA by the same group of professionals were evaluated. QoL was classified as regular in all domains evaluated (intestinal and systemic symptoms and emotional and social aspects). There were no differences in relation to gender, type of pouch or postoperative time. However, elderly patients showed a tendency toward lower scores. Having a professional activity was associated with higher scores in systemic symptoms and social aspects (p < 0.05). Patients with ileostomy showed lower values in the domains of systemic symptoms, emotional and social aspects (p <0.05). CONCLUSION: in all domains assessed, patients with IPAA for UC had QoL classified as regular. Ileostomy and lack of professional activity negatively influenced QoL. (AU)

OBJETIVO: Avaliar a qualidade de vida em portadores de RI por RCUI. PACIENTES E MÉTODOS: Foi empregado IBDQ, validado em português na avaliação da QoL em portadores de RI. RESULTADOS: Foram avaliados 31 pacientes submetidos a RI pelo mesmo grupo. QoL foi classificada como regular em todos os domínios avaliados (sintomas intestinais e sistêmicos e aspectos emocionais e sociais). Não houve diferenças em relação ao sexo, tipo de reservatório ou tempo de pós-operatório. Entretanto, pacientes idosos apresentaram uma tendência a escores mais baixos. Atividade profissional relacionou-se com escores mais altos em sintomas sistêmicos e aspectos sociais (p < 0,05). Portadores de ileostomia apresentaram valores mais baixos nos domínios sintomas sistêmicos, aspectos emocionais e sociais (p < 0,05). CONCLUSÃO: Em todos os domínios avaliados, portadores de RI por RCUI apresentaram QoL classificada como regular. Ileostomia e inatividade profissional influenciaram negativamente a QoL. (AU)

Resultados neonatais no parto vaginal espontâneo comparados aos dos partos com fórcipe de Simpson-Braun em primíparas / Neonatal outcome of spontaneous deliveries as compared to Simpson-Braun forceps deliveries in nulliparous women

OBJETIVO: comparar os resultados neonatais dos partos vaginais espontâneos ou assistidos com fórcipe de Simpson-Braun em nulíparas. MÉTODO: em estudo de corte retrospectivo foram avaliados dois grupos de primíparas atendidas no Centro Obstétrico do CAISM/UNICAMP, que tiveram parto vaginal sob analgesia epidural. O grupo fórcipe foi formado por 119 pacientes que tiveram parto a fórcipe de Simpson-Braun, e o grupo normal por 114 casos de parto vaginal espontâneo. Foram estudadas as variáveis neonatais imediatas como o estado do líquido amniótico e os índices de Apgar, assim como a evolução neonatal nos primeiros dias de vida. Para análise estatística foram utilizados os testes c², exato de Fisher e t de Student para comparação de médias e considerada significativa a diferença correspondente a p<0,05. RESULTADOS: as indicações para uso do fórcipe Simpson-Braun foram: alívio materno-fetal (90 casos) e abreviação de período expulsivo (29 casos). Nas pacientes atendidas com fórcipe Simpson-Braun houve 8 casos de laceração de canal de parto (6,7 por cento), valor semelhante ao observado no grupo de parto vaginal espontâneo. As médias de dias de internação das puérperas e neonatos foram idênticas (2,4). Os dois grupos foram semelhantes quanto aos índices de Apgar menores que 7 no primeiro (7,5 e 4,3 por cento) e quinto minuto (1,6 e 1,7 por cento) e quanto ao peso dos recém-nascidos (3.146 e 3.016 g). A evolução neonatal foi semelhante nos dois grupos. CONCLUSAO: o uso do fórcipe de Simpson-Braun mostrou-se seguro, quando comparado ao parto vaginal espontâneo.
