RESUMO

Polymeric materials, due to their excellent physicochemical properties and versatility found applicability in multiples areas, including biomaterials used in tissue regeneration, prosthetics (hip, artificial valves), medical devices, controlled drug delivery systems, etc. Medical devices and their applications are very important in modern medicine and the need to develop new materials with improved properties or to improve the existent materials is increasing every day. Numerous reasearches are activated in this domain in order to obtain materials/surfaces that does not have drawbacks such as structural failure, calcifications, infections or thrombosis. One of the most used material is poly(vinylchloride) (PVC) due to its unique properties, availability and low cost. The most common method used for obtaining tubular devices that meet the requirements of medical use is the surface modification of polymers without changing their physical and mechanical properties, in bulk. PVC is a hydrophobic polymer and therefore many research studies were conducted in order to increase the hydrophilicity of the surface by chemical modification in order to improve biocompatibility, to enhance wettability, reduce friction or to make lubricious or antimicrobial coatings. Surface modification of PVC can be achieved by several strategies, in only one step or, in some cases, in two or more steps by applying several techniques consecutively to obtain the desired modification / performances. The most common processes used for modifying the surface of PVC devices are: plasma treatment, corona discharge, chemical grafting, electric discharge, vapour deposition of metals, flame treatment, direct chemical modification (oxidation, hydrolysis, etc.) or even some physical modification of the roughness of the surface.

RESUMO

Objective: To discuss the characteristics of symptoms improvement based on the follow-up evaluation of Eustachian tube balloon dilation medium to long-term efficacy in patients with symptomatic Eustachian tube dysfunction (SETD). Methods: Patients from 2015 to 2017 were followed up after Eustachian tube balloon dilation (with the sense of aural fullness, or tinnitus and hearing ambiguity). All participants had been done ETDQ-7 before surgery and were re-evaluated with ETDQ-7 in follow-up. The improvement of overall and individual symptoms scores in ETDQ-7, the effects of gender and the difference of scores at different stages (12-18 months, 18-24 months and 24-30 months) after the operation were analyzed. Results: There were 29 patients, including 16 males and 13 females, whose age ranged from 20 to 62 years old. The medium to long-term score of ETDQ-7 significantly declined after surgery (27.0±7.9 vs. 14.1±7.5, P<0.05). Among all symptoms, symptoms like "blockage feeling in ear or being like under the water, constriction feeling" , "sound of blisters or explosions in the ear" decreased obviously (P<0.05). Comparing different stages after surgery, the scores of ETDQ-7 existed no difference (P>0.05). And the difference of gender showed no significant influence on surgery effects. Conclusion: The subjective symptoms of patients with Eustachian tube dysfunction diagnosed with SETD can be significantly improved in the medium to long-term follow-up after Eustachian tube balloon dilation, and the degree of improvement is not linearly related to the postoperative time.

RESUMO

Objective: To investigate the safety and efficacy of transcatheter perforation of pulmonary valve by micro-guidewire and balloon dilation in the treatment of neonatal pulmonary atresia with intact ventricular septum (PA-IVS). Methods: The retrospective study included 21 neonates (14 males and 7 females) with PA-IVS who underwent transcatheter micro-guidewire pulmonary valve perforation and balloon dilation in Xinhua Hospital from January 2012 to December 2018. All patients underwent the pulmonary valve perforation by micro-guidewire through the Simmons catheter. During the follow-up period at 1, 3, 6, 12 months postoperatively and annually thereafter, the operative efficacy and the development of the right ventricle (RV) were evaluated by echocardiography. Statistical analyses were performed using t test. Results: A total of 21 neonates with PA-IVS were enrolled, and 13 cases were diagnosed prenatally. The median age of surgery was 6 days, the weight was (3.2±0.5) kg. The balloon/valve ratio was 1.19±0.12, and the RV pressure measured by catheter was (121±33) mmHg (1 mmHg=0.133 kPa) . The immediate postoperative RV pressure was (47±13) mmHg. The median follow-up time was 30 months. All the cases enrolled achieved biventricular circulation without death and serious complications. According to the last follow-up data including 16 cases who were followed up for 1 year or longer, the pulmonary artery transvalvular pressure was (29±15) mmHg. The postoperation ratio of right to left ventricular transverse diameter was significantly higher than that before operation (0.86+0.10 vs. 0.73+0.13, t=-2.96, P=0.006). Compared with preoperative data, the postoperation pulmonary valvular diameter Z-score was significantly higher (-1.41±0.89 vs. -2.83±1.06, t=-3.65, P=0.001) and the tricuspid valvular diameter Z-score was significantly higher (-0.52±0.29 vs. -1.34±0.81, t=-3.55, P=0.001). Conclusion: Transcatheter perforation of pulmonary valve by micro-guidewire and balloon dilation is a safe and effective initial therapy for neonatal PA-IVS.

RESUMO

Objective: To explore the proper protective measures for pancreatic diseases treatment during the outbreak of 2019 coronavirus disease(COVID-19). Methods: Clinical data of four cases of patients that suffered COVID-19 from February 2(nd) to February 9(th), 2020 at Department of Pancreatic Surgery, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology were reviewed induding 4 males and 1 female, aging of 50, 51, 46, 87 years old, respectively. After the first patients cuffed nosocomial infection of COVID-19, the general protective measures were updated.Only one patient was admitted to each room alone, with no more than one caregiver. The body temperature of care givers was measured twice a day.Primary protections were applied to all staff.The floor was sterilized using disinfectant with an effective chlorine concentration of 1 000 mg/L. The protective measures for interventional procedures were as follow. Primary protection was applied to the operators of central venipuncture catheter, percutaneous abdominal/pleural drainage, percutaneous retroperitoneal drainage, percutaneous transhepatic cholangial drainage and other surgical procedures with local anesthesia and epidural anesthesia. Secondary protection was applied to the operators of endoscopic retrograde cholangiopancreatography and surgical procedures with general anesthesia. Results: There were four patients who were diagnosed as COVID-19, of which one died of COVID-19, two were cured, and one was still in hospital for COVID-19. After the update of protective measures, no more nosocomial infection of COVID-19 occurred. Two central venipuncture catheter, three percutaneous abdominal or pleural drainage, one percutaneous retroperitoneal drainage, one percuteneous transhepatic cholecyst drainage and one open surgery with general anesthesia were performed with no infection of operators. Conclusions: The caregivers of patients are potential infection source of COVID-19. Enhanced protective measures including the management measures of caregivers can decrease the risk of nosocomial infection of COVID-19.

RESUMO

Venovenous (VV) and venoarterial (VA) extracorporeal membrane oxygenation (ECMO) are effective support modalities to treat critically ill patients. ECMO-associated hemolysis remains a serious complication. The aim was to disclose similarities and differences in VA- and VV ECMO-associated hemolysis. This is a retrospective single-center analysis (January 2012 to September 2018) including 1,063 adult consecutive patients (VA, n = 606; VV, n = 457). Severe hemolysis (free plasma hemoglobin, fHb > 500 mg/l) during therapy occurred in 4% (VA) and 2% (VV) (p≤0.001). VV ECMO showed significantly more hemolysis by pump head thrombosis (PHT) compared to VA ECMO (9% vs. 2%; p≤0.001). Pretreatments (ECPR, cardiac surgery) of patients who required VA ECMO caused high fHb pre levels which aggravates the proof of ECMO-induced hemolysis (median (interquartile range), VA: fHb pre: 225.0 (89.3-458.0); VV: fHb pre: 72.0 (42.0-138.0); p≤0.001). The survival rate to discharge from hospital differed depending on ECMO type (40% (VA) vs. 63% (VV); p≤0.001). Hemolysis was dominant in VA ECMO patients, mainly caused by different indications and not by the ECMO support itself. PHT was the most severe form of ECMO-induced hemolysis that occurs in both therapies with low frequency, but more commonly in VV ECMO due to prolonged support time.

RESUMO

We describe a technique for performing hydrodissection in which the cannula tip is not advanced beyond the capsulorhexis edge, nor embedded into the cortex, but instead is placed within the capsulorhexis boundaries, pointing to the capsulorhexis edge, and angled slightly posterior to it. The fluid stream squirted from the cannula creates a cleavage plane between the capsule and cortex (hydrodissection), with a distinct wave dissecting the posterior capsule off the overlying cortex. By later rotating the angle slightly more posteriorly, hydrodelineation occurs, with the resultant "golden ring," and often, multiple "golden rings." The cleavage planes obtained using this technique may be more precise than when embedding the cannula tip under and beyond the capsulorhexis edge. This "remote hydrodissection" technique is easy and reproducible with soft and medium lenses, becoming more difficult to perform with harder cataracts. Hence, we recommend that this modification should initially be learned/tried on softer lenses.

RESUMO

There are numerous possible techniques for delivering local anaesthetic through peripheral nerve catheters. These include continuous infusions, patient-controlled boluses and programmed intermittent boluses. The optimal delivery regimen of local anaesthetic is yet to be conclusively established. In this review, we identified prospective trials of delivery regimens through peripheral nerve catheters. Our primary outcome was visual analogue scale scores for pain at 48 h. Secondary outcomes were: visual analogue scores at 24 h; patient satisfaction scores; rescue opioid use; local anaesthetic consumption; and nausea and vomiting. Network meta-analysis was used to compare these outcomes. Predefined sub-group analyses were performed. Thirty-three studies enrolling 1934 participants were included. In comparison with continuous infusion, programmed intermittent boluses improved visual analogue pain scores at both 48 and 24 h, the weighted mean difference (95%CI) being -0.63 (-1.12 to -0.14), p = 0.012 and -0.48 (-0.92 to -0.03), p = 0.034, respectively. Programmed intermittent boluses also improved satisfaction scores, the weighted mean difference (95%CI) being 0.70 (0.10-1.31), p = 0.023, and reduced rescue opioid use, the weighted mean difference (95%CI) in oral morphine equivalent at 24 h being -23.84 mg (-43.90 mg to -3.77 mg), p = 0.020. Sub-group analysis revealed that these findings were mostly confined to lower limb and truncal catheter studies; there were few studies of programmed intermittent boluses for upper limb catheters. Programmed intermittent boluses may provide optimal delivery of a local anaesthetic through peripheral nerve catheters. Further research is warranted, particularly to delineate the differences between upper and lower limb catheter locations, which will help clarify the clinical relevance of these findings.

RESUMO

BACKGROUND: Cavernous carotid fistulas (CCF) are anatomically complex vascular lesions. Treatment via the venous approach has been previously described and is highly dependent on the patency of the drainage pathways. The use of a unilateral approach to contralateral or bilateral shunts is technically challenging and not commonly described. We present our experience with the unilateral across-the-midline approach to both cavernous sinuses to treat shunts according to anatomic compartments to achieve anatomic cure. METHODS: Patients included in this study presented with either bilateral or unilateral shunts with unilateral venous drainage. We used a transarterial guiding catheter for road mapping and control angiography. A venous triaxial system was used to achieve support for distal navigation across the midline via the coronary sinus to the contralateral cavernous sinus. Coils were favored for embolization, with occasional complementary liquid embolic material. RESULTS: Five patients underwent complete occlusion in a single session. One patient required additional complementary transarterial embolization. Despite a successful unilateral approach to bilateral cavernous sinuses, 1 patient needed an additional ipsilateral transophthalmic venous approach to obliterate the anterior compartment of the cavernous sinus. No complications were encountered. Complete angiographic cure was observed in all patients by the end of the final procedures, with persistent occlusion in their follow-up imaging. CONCLUSIONS: Careful inspection of the venous anatomy and fistulization sites is critical when treating unilateral or bilateral carotid cavernous shunts. The contralateral venous route can serve as a safe approach when visualized. Crossing the midline via the anterior or posterior coronary sinuses is feasible and efficacious.

RESUMO

INTRODUCTION: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an adjunct used to temporize uncontrolled abdominopelvic hemorrhage. No published clinical data exist that describe average catheter lengths or balloon fill volumes necessary to occlude the aorta. METHODS: A prospective, single-institution registry was queried for patients who underwent placement of a Prytime ER-REBOA™ catheter. Demographic, catheter, hemodynamic, and morphometric data were measured. Linear regression analyses were performed to identify variables associated with insertion distances and balloon volumes. RESULTS: 45 patients underwent supraceliac REBOA: median catheter insertion distance 45 cm [IQR 42-46], balloon inflation volume 14 mL [IQR 8-19], systolic blood pressure (SBP) augmentation 50 mmHg [IQR 35-55]. 14 patients underwent infrarenal deployment: median catheter insertion distance 28.5 cm [IQR 26.5-32.5], balloon volume 10 mL [IQR 5-15]; SBP augmentation 55 mmHg [IQR 40-65]. Patient body metrics were not associated with catheter length or balloon volume. CONCLUSION: A wide range of catheter insertion distances and balloon fill volumes were necessary for correct REBOA positioning and occlusion. No single patient metric accurately correlated with catheter distance or balloon volume. LEVEL OF EVIDENCE: Level IV, Prognostic.

RESUMO

The objectives of this study were to evaluate the actual intraruminal sampling site of the ororuminal FLORA sampling device (Profs Products, Wittibreut, Germany), and to compare pH and volatile fatty acid (VFA) data obtained using FLORA and those obtained using a suction strainer introduced to the ventral ruminal sac via a rumen cannula. Five lactating multiparous Danish Holstein cows fitted with ruminal cannulas were used. All cows were fed the same diet once daily, and the diet was allowed ad libitum. Samples of rumen fluid and recordings were obtained 6 h after feeding at 3 occasions. Rumen fluid samples were taken using 2 devices: (1) the ororuminal FLORA sampling device and (2) a suction strainer inserted through the rumen cannula to the ventral ruminal sac and a 60-mL syringe for suction. Both sampling devices were inserted concomitantly, and samples of rumen fluid were obtained simultaneously with both devices. After sampling rumen fluid, the actual intraruminal placement of the FLORA sampling cup was manually assessed as being in either the cranial sac, the dorsal sac, the medial layer, or the ventral sac. Only VFA proportions, and not pH and VFA concentrations, were similar between rumen fluid samples obtained using FLORA and those obtained directly through the rumen cannula. The observed intraruminal sampling site of the FLORA sampling cup indicates that firm rumen digesta hampers the ability of the FLORA device to reach the ventral sac and impedes filling of the sampling cup and, consequently, increases the risk of saliva contamination of samples.

RESUMO

OBJECTIVE: To introduce a rapid and simple technique to engage and localize through left common carotid (LCCA) artery during selective carotid angiography using the same type of catheter (6F Medtronic™/launcher Judkins Right Guide Catheter, 4.0 Tip,2 Side holes, U.S.A.). METHODS: Patients were divided into two groups as new method and conventional method group including 295 and 292 prior to carotid angiography, respectively. The primary endpoints of this study included an analysis of total procedure time, time required for cannulation of left common carotid artery, fluoroscopy time and selective imaging success for left common carotid artery, feasibility, safety, amount of radio opaque agent and radiation exposure. RESULTS: Our novel method applied using a single catheter shortened total procedure time (5.41 ± 1.56 min. vs. 7.52 ± 2.48 min., respectively, p<0.001), fluoroscopy time (98 ± 9 sec. vs. 210 ± 19 sec., respectively, p<0.001), duration of left carotid artery cannulation (15 ± 1.2 sec vs. 42 ± 1.9 sec, respectively, p< 0.001). Use of our method reduced radiation exposure (120 ± 17 mGy vs. 217 ± 11 mGy, respectively, p<0.001), amount of contrast agent (44.99 ± 12.84 ml vs. 59.89 ± 18.93 ml, respectively, p<0.001). Aortic arch angiography was not needed in the first group compared with the conventional method group (0% vs. 29%, respectively, p<0.001). Also a higher success was achieved in cannulation of left common carotid artery using an identical catheter compared with application of conventional methods requiring use of different types of catheter (100% vs. 60%, respectively, p<0.001). No major complication and mortality was found due to use of both methods. However, a statistically insignificant elevation in minor complication was encountered in the patient group who underwent coronary angiography by the conventional method (3% vs. 7%, respectively, p<0.064). CONCLUSIONS: This new method is more easily applicable with a shorter duration for cannulation and localization of LCCA, safer for the patients with use of a limited amount of radio-opaque agent and finally cost-effective by requiring only one type of catheter and a limited.
