ABSTRACT

This study aimed to evaluate the appropriate sites of abdominocentesis for peritoneal fluid collection in cattle and to investigate the time of cell viability in vitro, comparing three methods of sample conservation. Twenty-one healthy cattle (19 females and 2 males) were subjected to a laparocentesis procedure to obtain peritoneal fluid, with punctures in three defined sites: left cranial, right cranial, and right caudal. The total peritoneal fluid collected was divided into three aliquots and maintained under three preservation conditions: room temperature (26°C), refrigeration (4°C), and room temperature (26°C) with the addition of 1µL of 10% formaldehyde per 1mL of peritoneal fluid. The peritoneal fluid analysis performed immediately after collection consisted of: physical examination (color, appearance, volume, and specific gravity), biochemical measures (pH, total protein, fibrinogen, creatinine, and glucose), and cellularity (total and differential counts). The determination of proteins and the examination of cells were repeated in each separate aliquot at two, four, six, and eight hours after harvest. Data were analyzed through repeated measures ANOVA or Friedman test. The harvest was productive in 67% of cattle. The left cranial and the right cranial puncture sites were the most appropriate. Peritoneal fluid analyzed after collection, the total protein concentration ranged from 1.4 to 3.6g/dL, and number of leukocytes ranged from 54 to 1,322 cells/µL; 60 to 95% of leukocytes were lymphocytes. The protein concentration decreased, but the absolute values of leukocytes, lymphocytes, and segmented neutrophils did not change up to eight hours after collection, independent of the maintenance method. Cell lysis was delayed by cooling, and the addition of formaldehyde did not help preserve the integrity of cellular morphology. Laparocentesis is a safe and secure procedure in cattle and maybe more productive when performed in specific sites on the left or right sides of the cranial abdominal wall. Peritoneal fluid samples may be analyzed with reliable results for up to eight hours after collection when kept refrigerated and for up to six hours when kept at room temperature.(AU)


O estudo teve como objetivo avaliar os locais adequados de laparocentese para a colheita de fluido peritoneal de bovinos e estabelecer o tempo de viabilidade celular in vitro, comparando três métodos de conservação. Vinte e um bovinos hígidos (19 fêmeas e 2 machos) foram submetidos ao procedimento de laparocentese para obtenção de fluido peritoneal, com punção em três pontos definidos: cranial esquerdo, cranial direito e caudal direito. O volume total do líquido peritoneal foi dividido em três alíquotas mantidas sob três métodos de conservação: temperatura ambiente (26°C); refrigeração (4°C); e temperatura ambiente (26°C) com adição de 1µL de formol 10% para cada 1mL de líquido peritonial. A análise do líquido peritoneal realizada imediatamente após sua obtenção consistiu em: exames físico (cor, aspecto, volume e densidade); bioquímicos (pH, proteína total, fibrinogênio, creatinina e glicose); e da celularidade (contagens total e diferencial). A determinação de proteínas e o exame da celularidade foram repetidos, em cada alíquota separada, as duas, quatro, seis e oito horas após a colheita. Análise de variâncias de medidas repetidas ou teste de Friedman foram empregados para avaliação ao longo do tempo. A colheita foi produtiva em 67% dos bovinos e os locais de punção craniais esquerdo e direito foram os mais adequados. A concentração de proteína total variou de 1,4 a 3,6g/dL e o número de leucócitos de 54 a 1.322 células/µL, com predomínio de linfócitos (60 a 95% das células) no fluido peritoneal analisado logo após a colheita. A concentração de proteínas diminuiu, mas os valores absolutos de leucócitos, de linfócitos e de neutrófilos segmentados não se modificaram até oito horas após a colheita, independente do método de manutenção das amostras. A lise celular foi retardada pela refrigeração e a adição de formol não contribuiu para preservar a integridade da morfologia celular. A laparocentese é um procedimento seguro e de execução fácil em bovinos sendo mais produtiva quando realizada em locais específicos à esquerda ou à direita craniais da parede abdominal. Amostras de fluido peritoneal podem ser analisadas com resultados confiáveis quando mantidas refrigeradas por até oito horas após a colheita e quando mantidas à temperatura ambiente por até seis horas.(AU)

ABSTRACT

RESUMO A infecção pelo coronavírus determinante da doença COVID-19, também conhecida como SARS-COV2 foi classificada nos últimos meses como pandemia. Essa é potencialmente fatal, representando enorme problema de saúde mundial. A disseminação, após provável origem zoonótica na cidade de Wuhan, China, resultou em colapso do sistema de saúde de diversos países, alguns com enorme impacto social e número grande de mortes descritas na Itália e Espanha. Medidas extremas intra e extra-hospitalares têm sido implementadas a fim de conter a transmissão e disseminação da COVID-19. No âmbito cirúrgico, enorme quantidade de procedimentos considerados não essenciais ou eletivos foram prorrogados ou suspensos até resolução da pandemia. No entanto, cirurgias de urgência e oncológicas não permitem que o paciente espere. Nesta publicação, sugerimos e ensinamos adaptação a ser feita com materiais de uso corriqueiro em laparoscopias para evitar a contaminação ou a disseminação entre as equipes assistenciais e os pacientes.


ABSTRACT The coronavirus infection, also known as SARS-COV2, has proven to be potentially fatal, representing a major global health problem. Its spread after its origin in the city of Wuhan, China has resulted in a pandemic with the collapse of the health system in several countries, some with enormous social impact and expressive number of deaths as seen in Italy and Spain. Extreme intra and extra-hospital measures have been implemented to decrease the transmission and dissemination of the COVID-19. Regarding the surgical practice, a huge number of procedures considered non-essential or elective were cancelled and postponed until the pandemic is resolved. However, urgent and oncological procedures have been carried out. In this publication, we highlight and teach adaptations to be made with commonly used materials in laparoscopy to help prevent the spread and contamination of the healthcare team assisting surgical patients.

ABSTRACT

ABSTRACT Vascular punctures are often necessary in critically ill patients. They are secure, but not free of complications. Ultrasonography enhances safety of the procedure by decreasing puncture attempts, complications and costs. This study reviews important publications and the puncture technique using ultrasound, bringing part of the experience of the intensive care unit of the Hospital Israelita Albert Einstein, São Paulo (SP), Brazil, and discussing issues that should be considered in future studies.


RESUMO Punções vasculares são muitas vezes necessárias em pacientes gravemente enfermos. São seguras, mas não isentas de complicações. A ultrassonografia associada à técnica de punção gera diminuição do número de tentativas, de complicações e de custos. O presente artigo revisou importantes publicações sobre o tema, bem como técnicas de punções, trazendo parte da experiência do centro de terapia intensiva de adultos do Hospital Israelita Albert Einstein, em São Paulo (SP) e discutindo tópicos que devem ser melhor explorados em estudos futuros.

ABSTRACT

ABSTRACT Objective: To report our experience of minimally invasive percutaneous nephrolithotomy(MPCNL) in managing upper urinary tract calculi complicated with severe spinal deformity. Materials and Methods: Between August 2001 to December 2012, 16 upper urinary calculi in 13 patients with severe spinal deformity were treated by MPCNL. Preoperative investigation of the respiratory function, evaluation of anatomy by intravenous urography (IVU) and CT scan, and preoperative kidney ultrasonagraphy with simulation of the percutaneous puncture were performed in all patients. The percutaneous puncture was guided by ultrasonography. Results: A total of 19 MPCNL procedures were performed in 16 kidneys, with an average 1.2 procedures in each kidney. Three kidneys needed two sessions of MPCNL, and 2 kidneys needed combined treatment with retrograde flexible ureterscopic lithotripsy. All procedures were successfully completed with no major complications during or after surgery. The mean (range) operative duration was 67 (20-150) min and the mean postoperative haemoglobin drop was 1.0 (0.2-3.1) g/dL. Complete stone-free status was achieved in 14 kidneys. At a mean follow-up of 48(3-86) months, recurrence of small lower calyx stone was detected in one patient. Recurrent UTI was documented by urine culture in two patients and managed with sensitive antibiotics. Conclusion: PCNL for patients with severe spinal deformities is challenging. Ultrasonography-assisted puncture can allow safe and successfully establishment of PCN tract through a narrow safety margin of puncture and avoid the injury to the adjacent organs. However, the operation should be performed in tertiary centers with significant expertise in managing complex urolithiasis.

ABSTRACT

ABSTRACT Objective: To compare the anesthetic techniques using propofol and fentanyl versus midazolam and remifentanil associated with a paracervical block with lidocaine in performing ultrasound-guided transvaginal oocyte aspiration. Methods: A randomized double-blind clinical trial (#RBR-8kqqxh) performed in 61 women submitted to assisted reproductive treatment. The patients were divided into two groups: anesthetic induction with 1mcg/kg of fentanyl associated with 1.5mg/kg of propofol (FP Group, n=32), in comparison with anesthetic induction using 0.075mg/kg of midazolam associated with 0.25mcg/kg/min of remifentanil, and paracervical block with 3mL of 2% lidocaine (MRPB Group, n=29). Main outcome measures: human reproduction outcomes, modified Aldrete-Kroulik index, hemodynamic parameters, and salivary cortisol. Results: The results revealed a higher number of embryos formed in the FP Group (p50=2 versus 1; p=0.025), gestation rate two times higher in the FP Group (44.4% versus 22.2%; p=0.127), less time to reach AK=10 in the MRPB Group (p50=10 versus 2; p<0.001), and lower mean of hemodynamic parameters in the MRPB Group (p<0.05). Conclusion: Anesthesia with fentanyl and propofol as well as with midazolam, remifentanil, and paracervical block offered satisfactory anesthetic conditions when performing assisted reproduction procedures, providing comfort for the patient and physician.


RESUMO Objetivo: Comparar as técnicas anestésicas utilizando propofol e fentanil contra midazolam e remifentanil associados a um bloqueio paracervical com lidocaína na aspiração de oócitos transvaginal guiada por ultrassom. Métodos: Ensaio clínico randomizado duplocego (#RBR-8kqqxh) realizado em 61 mulheres submetidas ao tratamento de reprodução assistida. As pacientes foram divididas em dois grupos: um grupo foi submetido à indução da anestesia com 1mcg/kg de fentanil associada com 1,5mg/kg de propofol (Grupo FP, n=32), em comparação com ao grupo submetido à indução da anestesia utilizando 0,075mg/kg de midazolam associada com 0,25mcg/kg/min de remifentanil, e bloqueio paracervical com 3mL de lidocaína a 2% (Grupo MRBP, n=29). Foram avaliados os resultados reprodutivos, índice modificado de Aldrete e Kroulik, parâmetros hemodinâmicos e cortisol salivar. Resultados: Foi encontrado um número mais elevado de embriões formados no Grupo FP (p50=2 versus 1; p=0,025), taxa de gestação duas vezes mais elevada no Grupo FP (44,4% versus 22,2%; p=0,127), menos tempo para alcançar AK=10 no Grupo MRBP (p50=10 versus 2; p<0,001) e média mais baixa de parâmetros hemodinâmicos do Grupo MRBP (p<0,05). Conclusão: Ambas as anestesias (com fentanil e propofol, e com midazolam, remifentanil e bloqueio paracervical) ofereceram condições anestésicas satisfatórias na realização de procedimentos realizados em reprodução assistida, proporcionando conforto para o paciente e médico.

ABSTRACT

The aim of this study was to explore the clinical efficacy of a novel retrograde puncture approach to establish a preperitoneal space for laparoscopic direct inguinal hernia repair with inguinal ring suturing. Forty-two patients who underwent laparoscopic inguinal hernia repair with retrograde puncture for preperitoneal space establishment as well as inguinal ring suturing between August 2013 and March 2014 at our hospital were enrolled. Preperitoneal space was successfully established in all patients, with a mean establishment time of 6 min. Laparoscopic repairs were successful in all patients, with a mean surgical time of 26±15.1 min. Mean postoperative hospitalization duration was 3.0±0.7 days. Two patients suffered from postoperative local hematomas, which were relieved after puncturing and drainage. Four patients had short-term local pain. There were no cases of chronic pain. Patients were followed up for 6 months to 1 year, and no recurrence was observed. Our results demonstrate that preperitoneal space established by the retrograde puncture technique can be successfully used in adult laparoscopic hernioplasty to avoid intraoperative mesh fixation, and thus reduce medical costs.

ABSTRACT

ABSTRACT Objective: To report our technique that helps locate the guidewire into the ureter enabling safe dilatation during PCNL. Materials and Methods: Cases in which the guidewire failed to pass into the ureter following successful puncture of the desired calyx were subjected to this technique. A second guidewire was passed through the outer sheath of a 9 Fr. metallic dilator cannula, passed over the first guidewire. The cannula and outer sheath were removed, followed by percutaneous passage of a 6/7.5 Fr ureteroscope between the two guidewires, monitoring its progress through both the endoscopic and fluoroscopic monitors. Once the stone was visualized in the calyx a guidewire was passed through the working channel and maneuvered past the stone into the pelvis and ureter under direct endoscopic vision. This was followed by routine tract dilatation. Results: This technique was employed in 85 out of 675 cases of PCNL carried out at our institute between Jan 2010 to June 2014. The mean time required for our technique, calculated from the point of introduction of the ureteroscope untill the successful passage of the guidewire down into the ureter was 95 seconds. There were no intraoperative or postoperative complications as a result of this technique. Guidewire could be successfully passed into the ureter in 82 out of 85 cases. Conclusions: Use of the ureteroscope introduced percutaneously through the puncture site in PCNL, is a safe and effective technique that helps in maneuvering the guidewire down into the ureter, which subsequently enables safe dilatation.

ABSTRACT

ABSTRACT Purpose: To evaluate the efficiency of a novel device coupled with ultrassound for renal percutaneous puncture. Materials and Methods: After establishing hydronephrosis, ten pigs had three calyxes of each kidney punctured by the same urology resident, with and without the new device ("Punctiometer"). Time for procedure completion, number of attempts to reach the calyx, puncture precision and puncture complications were recorded in both groups and compared. Results: Puncture success on the first attempt was achieved in 25 punctures (83%) with the Punctiometer and in 13 punctures (43%) without the Punctiometer (p=0.011). The mean time required to perform three punctures in each kidney was 14.5 minutes with the Punctiometer and 22.4 minutes without the Punctiometer (p=0.025). The only complications noted were renal hematomas. In the Punctiometer group, all kidneys had small hematomas. In the no Punctiometer group 80% had small hematomas, 10% had a medium hematoma and 10% had a big hematoma. There was no difference in complications between both groups. Conclusions: The Punctiometer is an effective device to increase the likelihood of an accurate renal calyx puncture during PCNL, with a shorter time required to perform the procedure.

ABSTRACT

Introducción: El objetivo de este trabajo fue evaluar prospectivamente los resultados del drenaje de gangliones dorsales de muñeca y la ruptura de su pedículo guiada por ecografía, y determinar su tasa de recidiva, las complicaciones y los resultados subjetivos. Materiales y Métodos: Se evaluaron prospectivamente 32 pacientes con gangliones dorsales sintomáticos de muñeca tratados mediante punción guiada por ecografía, aspiración del contenido y ruptura del pedículo con un trocar, entre enero de 2010 y junio de 2011. La edad de los pacientes promedió 31 años. Todos realizaban tareas administrativas, y retornaron a sus tareas habituales al día siguiente del procedimiento. El puntaje DASH previo al procedimiento fue, en promedio, de 2,90. El dolor previo al procedimiento promedió 7,75 puntos. Se separó a los pacientes en dos grupos, gangliones primarios (grupo 1: 19 pacientes) y gangliones recurrentes con cirugía previa (grupo 2: 13 pacientes). Resultados: Once pacientes tuvieron recidivas (34,3%) al año de seguimiento: 5 del grupo 1 (26,31%) y 6 del grupo 2 (46,1%). El puntaje DASH a los 6 meses promedió 1,91 (rango 1,02-3,98). El dolor a los 6 meses promedió 1,53 puntos (rango 0-4). Ningún paciente presentó complicaciones neurológicas o tendinosas, infección o hematomas (seguimiento promedio 6 meses). Conclusión: La técnica bajo control ecográfico es mínimamente invasiva con una tasa de recurrencia aceptable (26% en pacientes sin antecedente quirúrgico), considerando que plantea menores riesgos que los procedimientos quirúrgicos al igual que un menor costo y bajo costo laboral.


Background: The aim of this study was to prospectively evaluate the results of dorsal wrist ganglion cyst drainage and pedicle rupture under ultrasound guidance, and to determine recurrence rate, complications and subjective outcomes. Methods: Thirty-two patients with symptomatic dorsal wrist ganglion cysts treated by ultrasound-guided puncture, aspiration and pedicle rupture with a trochar, between January 2010 and June 2011, were prospectively evaluated. Age of the patients averaged 31 years. All patients returned to their previous daily activities the day after the procedure. DASH score before the procedure averaged 2.90 points. The pre-drainage visual analog scale for pain averaged 7.75 points. Patients were divided into two groups: without previous surgery (group 1: 19 patients) or with previous surgery (group 2: 13 patients). Results: Eleven patients had recurrences (34.3%) after a six-month follow-up: 5 patients in group 1 (26.31%) and 6 in group 2 (46.1%). DASH score at final follow-up averaged 1.91 points. Pain score at last follow-up averaged 1.53 points. There were no neurological or tendinous complications, infection or hematomas (follow-up 6 months). Conclusions: The technique under ultrasound guidance is minimally invasive with an acceptable recurrence rate (26% in patients without previous surgical interventions), considering that it presents less risk than surgical procedures, its lower cost and the immediate return to work.

ABSTRACT

OBJECTIVE: To investigate the accuracy, efficiency and radiation dose of a novel laser navigation system (LNS) compared to those of free-handed punctures on computed tomography (CT). MATERIALS AND METHODS: Sixty punctures were performed using a phantom body to compare accuracy, timely effort, and radiation dose of the conventional free-handed procedure to those of the LNS-guided method. An additional 20 LNS-guided interventions were performed on another phantom to confirm accuracy. Ten patients subsequently underwent LNS-guided punctures. RESULTS: The phantom 1-LNS group showed a target point accuracy of 4.0 +/- 2.7 mm (freehand, 6.3 +/- 3.6 mm; p = 0.008), entrance point accuracy of 0.8 +/- 0.6 mm (freehand, 6.1 +/- 4.7 mm), needle angulation accuracy of 1.3 +/- 0.9degrees (freehand, 3.4 +/- 3.1degrees; p < 0.001), intervention time of 7.03 +/- 5.18 minutes (freehand, 8.38 +/- 4.09 minutes; p = 0.006), and 4.2 +/- 3.6 CT images (freehand, 7.9 +/- 5.1; p < 0.001). These results show significant improvement in 60 punctures compared to freehand. The phantom 2-LNS group showed a target point accuracy of 3.6 +/- 2.5 mm, entrance point accuracy of 1.4 +/- 2.0 mm, needle angulation accuracy of 1.0 +/- 1.2degrees, intervention time of 1.44 +/- 0.22 minutes, and 3.4 +/- 1.7 CT images. The LNS group achieved target point accuracy of 5.0 +/- 1.2 mm, entrance point accuracy of 2.0 +/- 1.5 mm, needle angulation accuracy of 1.5 +/- 0.3degrees, intervention time of 12.08 +/- 3.07 minutes, and used 5.7 +/- 1.6 CT-images for the first experience with patients. CONCLUSION: Laser navigation system improved accuracy, duration of intervention, and radiation dose of CT-guided interventions.

ABSTRACT

OBJECTIVE: Here, we describe our experience with different therapeutic modalities used to treat cystic lymphangiomas in children in our hospital, including single therapy with OK-432, bleomycin and surgery, and a combination of the three modalities. METHODS: We performed a retrospective, cross-sectional study including patients treated from 1998 to 2011. The effects on macrocystic lymphangiomas and adverse reactions were evaluated. Twenty-nine children with cystic lymphangiomas without any previous treatment were included. Under general anesthesia, patients given sclerosing agents underwent puncture of the lesion (guided by ultrasound when necessary) and complete aspiration of the intralesional liquid. The patients were evaluated with ultrasound and clinical examinations for a maximum follow-up time of 4 years. RESULTS: The proportions of patients considered cured after the first therapeutic approach were 44% in the surgery group, 29% in the bleomycin group and 31% in the OK-432 group. These proportions were not significantly different. Sequential treatment increased the rates of curative results to 71%, 74% and 44%, respectively, after the final treatment, which in our case was approximately 1.5 applications per patient. CONCLUSION: The results of this study indicate that most patients with cystic lymphangiomas do not show complete resolution after the initial therapy, regardless of whether the therapy is surgical or involves the use of sclerosing agents. To achieve complete resolution of the lesions, either multiple operations or a combination of surgery and sclerotherapy must be used and should be tailored to the characteristics of each patient. .

ABSTRACT

O presente estudo teve como objetivo avaliar a Punção Aspirativa por Agulha Fina (PAAF) em diferentes técnicas de coloração, em lesões nodulares de cavidade oral e região de cabeça e pescoço, quanto a sua sensibilidade, especificidade e acurácia, nas colorações de Panótico, Papanicolau e Hematoxilina-Eosina . Foram selecionados 46 pacientes consecutivamente que procuraram a Clínica da Disciplina de Estomatologia Clínica da FOUSP, portadores de lesões nodulares em cavidade oral e região de cabeça e pescoço. Como critérios de inclusão foram selecionados pacientes de ambos os sexos, todas as etnias, acima dos 5 anos de idade, sem restrição de comorbidades e que foram realizadas PAAF com confirmação diagnóstica pela biópsia. Como critérios de exclusão da pesquisa estão os pacientes abaixo dos 5 anos de idade e pacientes que foram somente submetidos a PAAF sem confirmação diagnóstica pela biópsia. O material obtido pela PAAF foi enviado em 6 lâminas diferentes, corados pelo método de Panótico, Papanicolau e Hematoxilina-Eosina a um mesmo patologista apenas com o diagnóstico clínico. Após a emissão do laudo da PAAF, o laudo do anátomo patológico era emitido, servindo como padrão ouro. Após os cálculos, o resultado da sensibilidade, especificidade e acurácia para o método de coloração com o Panótico foram de 28,6%, 76%, 15,4, respectivamente, para o método de coloração com o Papanicolau foram de 71,4%, 76,7%, 23,3%, respectivamente e para o método de coloração com a Hematoxilina-Eosina foram de 82,1%, 23,3%, 28,6%, respectivamente...


The present study aimed to evaluate the Fine Needle Aspiration Biopsy in different staining techniques in nodular lesions of the oral cavity and head and neck region, as their sensitivity, specificity and accuracy, staining with Panoptic, Papanicolaou and Hematoxylin-Eosin. 46 patients who sought the Clinic of the Discipline of Clinical Stomatology at FOUSP were selected consecutively, with nodular lesions in the oral cavity and head and neck region. Inclusion criteria were patients of both sexes, all ethnicities, above 5 years-old, with no restriction of comorbidities and FNAB performed with confirmation by biopsy. Exclusion criteria were patients under 5 years-old and patients who only underwent FNAB without confirmation by biopsy. The material obtained by FNAB was sent on 6 different slides, stained by the method of Panoptic, Papanicolaou and Hematoxylin-Eosin, to the same pathologist only with the clinical diagnosis. After the final report of FNAB, the biopsy report was issued, serving as gold standard. After the calculations, the results of sensitivity, specificity and accuracy for Panoptic staining were 28.6%, 76% and 15.4%, respectively...

ABSTRACT

OBJECTIVE: The purpose of our study was to assess the feasibility of performing percutaneous radiologic gastrostomy (PRG) in patients who had undergone partial gastrectomy and to evaluate factors associated with technical success. MATERIALS AND METHODS: Nineteen patients after partial gastrectomy, who were referred for PRG between April 2006 and April 2012, were retrospectively analyzed. The remnant stomach was punctured using a 21-gauge Chiba-needle. A single anchor was used for the gastropexy and a 12-Fr or 14-Fr gastrostomy tube was inserted. Data were collected regarding the technical success, procedure time, and presence of any complications. Univariable analyses were performed to determine the factors related to the technical success. RESULTS: Percutaneous radiologic gastrostomy was technically successful in 10 patients (53%), while a failed attempt and failure without an attempt were observed in 5 (26%) and 4 (21%) patients, respectively. Percutaneous radiologic jejunostomy was successfully performed in 9 patients who experienced technical failure. In the 10 successful PRG cases, the mean procedure time was 6.35 minutes. Major complications occurred in 2 patients, tube passage through the liver and pneumoperitonum in one and severe hemorrhage in the other. The technical success rate was higher in patients with Billroth I gastrectomy (100%, 6/6) than in patients with Billroth II gastrectomy (31%, 4/13) (p = 0.011). CONCLUSION: Percutaneous radiologic gastrostomy can be successfully performed using the one-anchor technique in approximately half of the patients after partial gastrectomy.

ABSTRACT

PURPOSE: To compare curative effect of different treatments for hypertensive cerebral hemorrhage of 25 to 35ml. METHODS: In this study, 595 cases were enrolled and grouped regarding treatments including conservative treatment, evacuation with microinvasive craniopuncture technique within 6h and 6-48h after the attack. RESULTS: After follow up for three months after the attack, the assessment based on the Activity of Daily Living (ADL) indicated no significant difference among conservative treatment and surgical interventions (p>0.05). However, surgical interventions showed advantages of shorter hospitalization, quick removal of hematoma and obvious reduction of cost. CONCLUSION: The microinvasive craniopuncture technique to drain the hematoma within 6-48h may be a good way in treating hypertensive hemorrhage of basal ganglia region.

ABSTRACT

OBJECTIVES: Evaluate the safety and effectiveness of a training program for performing ultrasound-guided internal jugular vein cannulation in critically ill patients. METHODS: Cohort prospective study, evaluating adult patients admitted in a teaching intensive care unit (ICU). Catheter placement was performed by an ICU medical resident. The patient's baseline characteristics, vessel's position and operator experience were the evaluated variables. The main outcomes were cannulation success rate and incidence of major complications. RESULTS: A total of 118 consecutive patients were enrolled between May 2008 and November 2009. The success rate of ultrasound guided catheter placement was 90 percent (106/118), 77 percent in the first attempt. Major complications occurred in 4 percent of the cases (n = 5) and were not associated with the analyzed variables. Inability to place the guide wire was the reason for 58 percent (7/12) of the failures. Operators with more than 15 previous ultrasound guided cannulations had an increased success rate (95 percent vs. 79 percent, p = 0.01) and increased failure was related to previous catheterization (26 percent vs. 7 percent, p = 0.02). CONCLUSION: Learning ultrasound guidance for IJV vein cannulation was safe and feasible in ICU patients. This process was not associated to complications and better results were achieved across the spectrum of operator experience.


OBJETIVO: Avaliar a segurança e efetividade de um programa de treinamento para cateterização da veia jugular interna guiada por ultrassom em pacientes críticos. MÉTODOS: Estudo de coorte prospectivo, avaliando pacientes adultos internados em uma unidade de terapia intensiva com programa de ensino. Os médicos residentes do serviço realizaram as punções de veia jugular interna guiadas por ultrassom. Foram avaliadas as características de base dos pacientes, sintopia dos vasos e experiência dos operadores. Os desfechos primários foram a taxa de sucesso da cateterização e a incidência de complicações graves. RESULTADOS: No período entre maio de 2008 e novembro de 2009 foram avaliados 118 pacientes. A taxa de sucesso da punção guiada por ultrassom foi 90 por cento (106/118), 77 por cento dessas na primeira tentativa. Complicações graves ocorreram em 4 por cento dos casos (n = 5) e não foram associadas às variáveis analisadas. Incapacidade de progredir o fio-guia foi a razão de 58 por cento (7/12) das falhas. Operadores com mais de 15 punções guiadas por ultrassom obtiveram uma maior taxa de sucesso (95 por cento vs. 79 por cento, p = 0,01) e pacientes com cateterização prévia apresentaram um maior número de falhas (26 por cento vs. 7 por cento, p = 0,02). CONCLUSÃO: O aprendizado da técnica de punção de veia jugular interna guiada por ultrasssom é seguro e efetivo em pacientes críticos. Este processo não esteve associado a um aumento da taxa de complicações e melhores resultados são obtidos à medida que aumenta a experiência do operador.
