Application of an individualized and reassemblable 3D printing navigation template for accurate puncture during sacral neuromodulation.

OBJECTIVE: To evaluate the feasibility and safety of an individualized and reassemblable three-dimensional (3D) printing navigation template for making accurate punctures during sacral neuromodulation (SNM). METHODS: From July 2016 to July 2017, 24 patients undergoing SNM were enrolled. Conventional X-ray guidance was used in the control group, which included 14 patients, while the 3D printing template was used in the experimental group, which included 10 patients. The number of punctures, the average puncture time, the exposure to X-ray, the adjustment time during the operation and the testing of the SNM device, the infection and haemorrhage rate, and the implantable pulse generator (IPG) implantation rates were compared between the two groups. RESULTS: In total, 24 patients successfully underwent stage I. When comparing the control group and the experimental group, the number of punctures were 9.6 ± 7.7 and 1.5 ± 0.7, respectively; the average puncture times were 35.4 ± 14.6 and 4.1 ± 2.2 min, respectively; and the X-ray exposure levels were 8.37 ± 4.83 mAs and 2.34 ± 0.54 mAs, respectively. No postoperative complications were reported in either group. The IPG implantation rates were not different between the two groups. CONCLUSION: The 3D printing template for SNM can help us to perform accurate and quick punctures into the target sacral foramina, reduce X-ray exposure, and shorten the operation time. For patients with obesity, sacral variation, sacral bone fractures or losses and for patients who are unable to tolerate the prone position during operation, use of the 3D printing template is recommended.

Comparison of the clinical efficacy of craniotomy and craniopuncture therapy for the early stage of moderate volume spontaneous intracerebral haemorrhage in basal ganglia: Using the CTA spot sign as an entry criterion.

OBJECTIVES: Surgical treatment is widely used for haematoma removal in spontaneous intracerebral haemorrhage (ICH) patients, but there is controversy about the selection of surgical methods. The CT angiography (CTA) spot sign has been proven to be a promising factor predicting haematoma expansion and is recommended as an entry criterion for haemostatic therapy in patients with ICH. This trial was designed to evaluate the clinical efficacy of two surgical methods (haematoma removal by craniotomy and craniopuncture combined with urokinase infusion) for patients in the early stage (≤6h from symptom onset) of spontaneous ICH with a moderate haematoma volume (30 ml - 60 ml). PATIENTS AND METHODS: From January 2012 to July 2017, 196 eligible patients treated in our institution were enrolled according to the inclusion criteria. The patients were divided into the CTA spot sign positive type and CTA spot sign negative type according to the presence or absence of the CTA spot sign. For each type, the patients were randomly assigned to two groups, i.e., the craniotomy group, in which patients underwent craniotomy with haematoma removal, and the craniopuncture group, in which patients underwent minimally invasive craniopuncture combined with urokinase infusion therapy. Neurological function was evaluated with the Scandinavian Stroke Scale (SSS) at day 14. The disability level and the activities of daily living were assessed using a modified Rankin Scale (mRS) and Barthel Index (BI) at day 90. Case fatalities were recorded at day 14 and 90. Complications were recorded during hospitalization. RESULTS: For the CTA spot sign positive type, the craniotomy group had a higher SSS than that in the craniopuncture group (P < 0.05) at day 14. The rebleeding rate was higher in the craniopuncture group than that in the craniotomy group (P < 0.05) during hospitalization. The craniotomy group had a lower mRS than that in the craniopuncture group (P < 0.01) and had a higher BI than that in the craniopuncture group (P < 0.05) at day 90. There was no statistically significant difference in the fatality rate between the two groups. For the CTA spot sign negative type, there were no significant differences in the SSS, mRS, BI, fatality rate and complication rate between the two groups. CONCLUSION: ICH can be divided into the CTA spot sign positive and negative type according to the presence or absence of the CTA spot sign. For the CTA spot sign positive type, patients can benefit from craniotomy with haematoma removal, which can reduce the postoperative rebleeding rate and improve the prognosis. For the CTA spot sign negative type, both craniotomy and craniopuncture are applicable. Considering simple procedure and minor surgical injury, craniopuncture can be a more reasonable choice.

Brinquedo terapêutico no procedimento de punção venosa: estratégia para reduzir alterações comportamentais / Juguete terapéutico durante el procedimiento de punción venosa: estrategia para reducir alteraciones de comportamiento / Therapeutic toy during the procedure of venipuncture: a strategy to reduce behavioral changes

Introdução: A enfermagem pediátrica deve estar atenta aos subsídios da assistência que tornem possível um melhor manejo da dor e da ansiedade oriundas da hospitalização infantil, geralmente, causadas pela realização de procedimentos invasivos como a punção venosa. O uso do Brinquedo Terapêutico Instrucional (BTI) pode representar uma intervenção eficaz para lidar com os efeitos negativos da hospitalização. Objetivo: Comparar as reações manifestadas pela criança frente ao preparo para punção venosa antes e após o uso do BTI. Materiais e Métodos: A pesquisa é analítica, exploratória e de abordagem quantitativa. Para análise dos dados foi utilizado o teste de McNemar. A amostra consistiu de 21 crianças hospitalizadas, pré-escolares e escolares, a coleta deu-se entre junho e agosto de 2012, em unidade de internação pediátrica do Crato, CE (Brasil). Resultados e Discussão: Após o uso do BTI, observou-se uma redução na frequência de variáveis comportamentais que indicam menor adaptação ao procedimento, com significância estatística em especial para: “Solicita a presença Materna” e “Evita olhar para o Profissional” (p<0,001). A realização das sessões também potencializou a frequência de, praticamente, todos os comportamentos associados a uma melhor aceitação ao preparo ou realização da punção venosa, com destaque para “Observa o Profissional” (p<0,001) e “Sorri” (p<0,005). Conclusões: O BTI constitui relevante intervenção para a enfermagem pediátrica, sendo necessário, para sua aplicação sistematizada, articular ações que visem uma maior sensibilização dos órgãos gestores dos serviços de pediatria, maior capacitação dos profissionais envolvidos e melhor abordagem do ensino do brinquedo terapêutico nos cursos de graduação de enfermagem.

Introduction: Pediatric nurses should always be attentive to the care subsidies that make possible a better control of pain and anxiety generated by infant hospitalization. Generally, these adverse feeling in children are caused by the realization of intrusive procedures, such as venipuncture. The use of the Therapeutic Toy Instructional (TTI) may represent an effective intervention to deal with the negatives effects of hospitalization. Objective: To compare the reactions expressed by the child, exposed to venipuncture, before and after the use of TTI. Materials and Methods: The research is analytical, exploratory and quantitative approach. For analysis of the data was employed the McNemar test. The sample consisted of 21 hospitalized children, pre-school and school ages, the process of data was collected between June and August of 2012 in a pediatric unit from Crato, CE (Brazil). Results and Discussion: After using the TTI, there was a reduction in frequency of behavioral variables that indicate less adaptation to the procedure, particularly for “Require the presence of mother" and "Try not to look for the Professional" (p <0.001). The realization of the sessions also increased the frequency of many behaviors associated with better acceptance of the procedure, especially: "Look for the Professional" (p <0.001) and "Smile" (p <0.005). Conclusions: The TTI is a relevant intervention for pediatric nursing; to use it in a systematic way is needed: planning actions aimed at increasing awareness among managers of pediatric services, better training of professionals and the inclusion of teaching of therapeutic toy in nursing courses.

Added value of transoesophageal echocardiography during transseptal puncture performed by inexperienced operators.

AIMS: Transseptal puncture (TP) appears to be safe in experienced hands; however, it can be associated with life-threatening complications. The aim of our study was to demonstrate the added value of routine use of transoesophageal echocardiography (TEE) for the correct positioning of the transseptal system in the fossa ovalis, thus potentially preventing complications during fluoroscopy-guided TP performed by inexperienced operators. METHODS AND RESULTS: Two hundred and five patients undergoing pulmonary vein isolation procedure (PVI) for drug-resistant paroxysmal or persistent atrial fibrillation were prospectively included. When the operator (initially blinded to TEE) assumed that the transseptal system was in a correct position according to fluoroscopical landmarks, the latter was then checked with TEE unblinding the physician. If necessary, further refinement of the catheter position was performed. Refinement >10 mm, or in case of catheter pointing directly at the aortic root or posterior wall were considered as major repositioning. Thirty-four patients required major repositioning. Regression analysis revealed age (P: 0.0001, Wald: 12.9, 95% confidence interval: 1.04-1.16), left atrial diameter (P: 0.01, Wald: 6.6, 95% confidence interval: 1.04-1.34), previous PVI (P: 0.01, Wald: 6.3, 95% confidence interval: 1.31-8.76), and atrial septal thickness (P: 0.03, Wald: 4.5, 95% confidence interval: 1.05-3.4) as independent predictors of major revision with TEE. CONCLUSION: Routine 2D TEE in addition to traditional fluoroscopic TP appears to be very useful to guide the TP assembly in a correct puncture position and thus, to avoid TP-related complications. However, further randomized prospective comparative studies are necessary to support these suggestions.
