Comparison of 2 Midline Catheter Devices With Differing Antithrombogenic Mechanisms for Catheter-Related Thrombosis: A Randomized Clinical Trial.

Importance: Data regarding upper extremity midline catheter (MC)-related thrombosis (CRT) are sparse, with some evidence indicating that MCs have a high rate of CRT. Objective: To compare 2 MCs with differing antithrombogenic mechanisms for this outcome. Design, Setting, and Participants: In this parallel, 2-arm randomized clinical trial, 496 adult patients hospitalized at a tertiary care suburban academic medical center who received an MC were assessed for eligibility between January 1, 2019, and October 31, 2020, and 212 were randomized. Interventions: Inpatients were randomized to receive a 4F antithrombotic MC (MC-AT) or a 4.5F antithrombotic and antimicrobial MC (MC-AT-AM). Main Outcomes and Measures: The primary outcome was symptomatic midline CRT inclusive of deep vein thrombosis or superficial venous thrombophlebitis within 30 days after insertion. Secondary outcomes included catheter-associated bloodstream infection and catheter failure. Results: A total of 191 patients (mean [SD] age, 60.2 [16.7] years; 114 [59.7%] female) were included in the final analysis: 94 patients in the MC-AT group and 97 in the MC-AT-AM group. Symptomatic midline CRT occurred in 7 patients (7.5%) in the MC-AT group and 11 (11.3%) in the MC-AT-AM group (P = .46). Deep vein thrombosis occurred in 5 patients (5.3%) in the MC-AT group and 5 patients (5.2%) in the MC-AT-AM group (P > .99). Pulmonary embolism occurred in 1 patient in the MC-AT group. No catheter-associated bloodstream infection occurred in either group. Premature catheter failure occurred in 22 patients (23.4%) in the MC-AT group and 20 (20.6%) in the MC-AT-AM group (P = .64). In Cox proportional hazards regression analysis, no statistically significant difference was found between groups for the risk of catheter failure (hazard ratio, 1.27; 95% CI, 0.67-2.43; P = .46). Conclusions and Relevance: No difference was found in thrombosis in MCs with 2 distinct antithrombogenic mechanisms; however, the risk of CRT in both groups was high. Practitioners should strongly consider the safety risks associated with MCs when determining the appropriate vascular access device. Trial Registration: ClinicalTrials.gov Identifier: NCT03725293.

Multicatheter interstitial brachytherapy versus stereotactic radiotherapy with CyberKnife for accelerated partial breast irradiation: a comparative treatment planning study with respect to dosimetry of organs at risk.

BACKGROUND: The aim of the study was to dosimetrically compare multicatheter interstitial brachytherapy (MIBT) and stereotactic radiotherapy with CyberKnife (CK) for accelerated partial breast irradiation (APBI) especially concerning the dose of organs at risk (OAR-s). PATIENTS AND METHODS: Treatment plans of thirty-two MIBT and CK patients were compared. The OAR-s included ipsilateral non-target and contralateral breast, ipsilateral and contralateral lung, skin, ribs, and heart for left-sided cases. The fractionation was identical (4 x 6.25 Gy) in both treatment groups. The relative volumes (e.g. V100, V90) receiving a given relative dose (100%, 90%), and the relative doses (e.g. D0.1cm3, D1cm3) delivered to the most exposed small volumes (0.1 cm3, 1 cm3) were calculated from dose-volume histograms. All dose values were related to the prescribed dose (25 Gy). RESULTS: Regarding non-target breast CK performed slightly better than MIBT (V100: 0.7% vs. 1.6%, V50: 10.5% vs. 12.9%). The mean dose of the ipsilateral lung was the same for both techniques (4.9%), but doses irradiated to volume of 1 cm3 were lower with MIBT (36.1% vs. 45.4%). Protection of skin and rib was better with MIBT. There were no significant differences between the dose-volume parameters of the heart, but with MIBT, slightly larger volumes were irradiated by 5% dose (V5: 29.9% vs. 21.2%). Contralateral breast and lung received a somewhat higher dose with MIBT (D1cm3: 2.6% vs. 1.8% and 3.6% vs. 2.5%). CONCLUSIONS: The target volume can be properly irradiated by both techniques with similar dose distributions and high dose conformity. Regarding the dose to the non-target breast, heart, and contralateral organs the CK was superior, but the nearby organs (skin, ribs, ipsilateral lung) received less dose with MIBT. The observed dosimetric differences were small but significant in a few parameters at the examined patient number. More studies are needed to explore whether these dosimetric findings have clinical significance.

Treating peritoneal dialysis catheter exit-site granulomas with chlorhexidine swabstick: A pilot study.

BACKGROUND: Silver nitrate cauterisation is the conventional treatment for peritoneal dialysis catheter exit-site granulomas. However, it requires to be performed by nurses, patients often experience pain and chemical burns. Therefore, the appropriateness and applicability of using 2% aqueous chlorhexidine swabstick as an alternative was explored in two nephrology centres in Hong Kong. OBJECTIVE: To examine possibility of conducting full trial using chlorhexidine swabstick compared with silver nitrate. DESIGN: A pilot study. PARTICIPANTS: Fort-four patients with exit-site granulomas were equally, randomly allocated to receive chlorhexidine swabstick or silver nitrate. MEASUREMENTS: Both groups were followed for 6 weeks to evaluate the time of granuloma subsidence and adverse effects. Pain and treatment satisfaction were assessed using numerical rating scale and self-developed questionnaire, respectively. RESULTS: Healing rates were 94.4% (17 of 18) using chlorhexidine swabstick,100% (21 of 21) using silver nitrate (p = 0.46). The mean time of granuloma subsidence was significantly longer when using chlorhexidine swabstick (32.8 days) than silver nitrate (12.3 days, p=0.02). The chlorhexidine swabstick group reported significantly fewer adverse effects (11.1%, 2 of 18, p = 0.01) compared with the silver nitrate group (52.4%, 11 of 21). The chlorhexidine swabstick group had lower mean pain score (0.5 of 11) than the silver nitrate group (2.4 of 11, p < 0.01). The satisfaction scores between the two groups had no substantial difference. CONCLUSION: Chlorhexidine swabstick took long time to remove granulomas but had similar success rate, less pain, fewer adverse effects than silver nitrate. Additional research is warranted to examine the applicability of chlorhexidine swabstick.

Impact of side-hole geometry on the performance of hemodialysis catheter tips: A computational fluid dynamics assessment.

Hemodialysis catheters are used to support blood filtration, yet there are multiple fundamentally different approaches to catheter tip design with no clear optimal solution. Side-holes have been shown to increase flow rates and decrease recirculation but have been associated with clotting/increased infection rates. This study investigates the impact of changing the shape, size and number of side-holes on a simple symmetric tip catheter by evaluating the velocity, shear stress and shear rate of inflowing blood. A platelet model is used to examine the residence time and shear history of inflowing platelets. The results show that side-holes improve the theoretical performance of the catheters, reducing the maximum velocity and shear stress occurring at the tip compared to non-side-hole catheters. Increasing the side-hole area improved performance up to a point, past which not all inflow through the hole was captured, and instead a small fraction slowly 'washed-out' through the remainder of the tip resulting in greater residence times and increasing the likelihood of platelet adhesion. An oval shaped hole presents a lower chance of external fibrin formation compared to a circular hole, although this would also be influenced by the catheter material surface topology which is dependent on the manufacturing process. Overall, whilst side-holes may be associated with increased clotting and infection, this can be reduced when side-hole geometry is correctly implemented though; a sufficient area for body diameter (minimising residence time) and utilising angle-cut, oval shaped holes (reducing shear stress and chances of fibrin formation partially occluding holes).

Análisis de parámetros de calidad y de costos, de uso del catéter venoso central de inserción periférica frente al catéter de inserción central, en población pediátrica del Hospital Universitario del Valle, Cali, Colombia. 2011-2014 / Analysis of quality parameters and costs of using the central venous catheter of peripheral insertion versus the central insertion catheter in pediatric patients at Hospital Univeristario Del Valle, Cali Colombia 2011-2014

Objetivo: estimar parámetros de calidad y de costos en el procedimiento de inserción de Catéter Venoso Central y el Catéter Venoso Central de inserción periférica. Metodología: Se evaluaron las historias de niños (edad 31 días -15 años ), que ingresaron al Hospital Universitario del Valle, entre enero de 2011 y diciembre de 2014, que requirieron canalización de una vena central. Se evaluaron variables demográficas, de calidad y se estimaron costos de ambos procedimientos. Resultados: Se evaluaron 100 procedimientos de inserción Central y 100 de inserción periférica, los últimos tuvieron menor tiempo de espera, se realizaron en la habitación, no requirieron ayuno, ni traslado al quirófano, a un menor costo, lo cual impactó la oportunidad de administración de tratamiento farmacológico, la evolución y la estancia hospitalaria. Conclusiones: Se recomienda que el procedimiento de inserción periférica sea la primera elección en niños que requieran tratamientos endovenosos mayores a cinco días, para esto es necesario conformar un grupo que supervise el funcionamiento de los catéteres y brinde educación continua al personal de salud de los servicios de hospitalización y a familiares, contar con una sala de procedimiento para la inserción del PICC que brinde seguridad y adecuado manejo del dolor.

Aim: to estimate quality and cost parameters of central venous catheter insertion peripheral and central venous catheter procedures. Methods: we reviewed records of 200 children (31 days - years old), hospitalised at a University Hospital between January 2011 and December 2014 who required central vein access. We assessed demographic, quality variables and cost of both procedures. Results: we reviewed records of 100 central insertion and 100 peripheral insertion procedures. Peripheral insertions had less waiting time, were conducted next to the child's bed, without need for fasting or transfering to the operating room, at a lower cost, all of these ensured timely administration of medicaments and nutrition, which resulted in lower stance time. The peripheral insertion also freed surgeon and operating room time to perform other interventions. Conclusions: We recommend that peripheral insertion procedure should be the first choice in children requiring intravenous treatments longer than five days. In order to establish a periferal insertion procedure in a hospital, a team is required to follow-up the patients and provide continuing education to health personnel in services and to family members, there is also a need for an appropiate space for insertion procedures and pain management.

Intrasinus bolstering of traumatic maxillary sinus fractures by using Foley catheter balloons in two foals.

OBJECTIVE: To describe the repair of unstable facial fractures by using Foley catheter balloons as intrasinus bolsters. STUDY DESIGN: Case report ANIMALS: Two weanling foals with unilateral fractures of the sinus and orbit secondary to kick injuries. Preoperative imaging that included positive contrast dacrocystorhinography and computed tomography confirmed severe comminution of facial fractures and nasolacrimal duct disruption in both foals. METHODS: Small bone fragments were surgically removed, and large fragments were retained even when denuded of periosteum. Repair procedures included nasolacrimal canaliculosinusotomy and suturing fracture fragments together with polydioxanone sutures. After fixation, the fracture fragments could be depressed into the sinus with manual pressure, so two intrasinus Foley catheters were placed to bolster the sinus wall, with the tubing exiting through a frontal sinus trephine. The skin was completely closed over the fractures. Catheters and nasolacrimal stenting were maintained in place during fracture healing. RESULTS: One foal prematurely dislodged catheters and nasolacrimal stent 11 days after fixation. The catheters and stenting were removed as planned 4 weeks after surgery in the second foal. Wound, fracture healing, and overall cosmesis was good in both foals, and epiphora resolved. Surgical site infection, sinusitis, and sequestration did not occur. Both foals became high-level performance horses with acceptable cosmetic outcome and good bilateral nasal airflow. CONCLUSION: Foley catheter balloons supported sinus fracture repair and maintained stability of the surgical reconstruction during convalescence. CLINICAL SIGNIFICANCE: Suture repair of comminuted sinus fractures can be supported by using Foley catheters, which are readily available.

Abdominal and pelvic radiographs of medical devices and materials- part 2: neurologic and genitourinary devices and materials.

Radiographs of the abdomen and pelvis are routinely obtained as a standard part of clinical care for the abdomen and pelvis. Brisk advances in technology over the last few decades have resulted in a multitude of medical devices and materials. Recognizing and evaluating these devices on abdominal and pelvic radiographs are critical, yet increasingly a difficult endeavor. In addition, multiple devices serving different purposes may have a similar radiographic appearance and position causing confusion for the interpreting radiologist. The role of the radiologist is to not only identify accurately these medical objects, but also to confirm for their accurate placement and to recognize any complications that could affect patient care, management or even be potentially life threatening. An extensive online search of literature showed our review article to be the most comprehensive work on medical devices and materials of the abdomen and pelvis, and in this second part of our two-part series, we discuss in depth about the neurologic and genitourinary devices seen on abdominal and pelvic radiographs.

Undetected Cortrak tube misplacements in the United Kingdom 2010-17: An audit of trace interpretation.

OBJECTIVES: Determine why Cortrak-guided, undetected tube misplacement may occur in relation to the system of trace interpretation used. METHODOLOGY: From 2010 to 2017 we obtained seven of the eight Cortrak traces from the United Kingdom where misplacement was undetected and the patient received feed. Seven suffered serious harm. Each misplacement was interpreted by three systems: screen position, manufacturer guidance and gastrointestinal (GI) flexures. SETTING: National and local records. MAIN OUTCOME MEASURES: Ability to identify misplacement. RESULTS: Traces that were later identified as misplacements, could not be differentiated from GI position when they wholly or partially: a) overlapped with the GI screen area plotted from historical records (57-71%) or b) met both manufacturer guidance criteria or were confused with receiver misplacement or unusual anatomy and reached the lower left quadrant (14-71%). Conversely, all lung misplacements were identified as unsafe using the GI flexure system. All three systems failed to detect the intra-peritoneal trace. Traces were inconsistently stored by healthcare centres. CONCLUSION: Trace file storage should be mandated by and accessible to relevant health authorisation bodies to improve safety research. Screen position alone and manufacturer guidance fail to consistently differentiate the shape of safe from unsafe traces. GI flexure interpretation appears safer but requires testing in larger studies.

Trans-tract electrocoagulation can decrease the need for postoperative nephrostomy tube after endoscopic combined intrarenal surgery.

AIM: To assess the efficacy and safety of trans-tract electrocoagulation at the end of endoscopic combined intrarenal surgery for renal or ureteral stones. METHODS: The present study included patients who underwent endoscopic combined intrarenal surgery from May 2010 to March 2018. After June 2013, the trans-tract electrocoagulation procedure, to coagulate bleeding from the access tract using a resectscope was carried out at the end of the operation. We compared the patients' background and surgical outcomes between patients with and without trans-tract electrocoagulation. RESULTS: Between the trans-tract electrocoagulation (n = 225) and non-trans-tract electrocoagulation (n = 72) groups, the stone number was significantly smaller (1:2:3 or more, 126:72:27 vs 59:10:3, P = 0.001) and the initial stone-free rates were significantly higher (80% vs 72%, P = 0.006) in the trans-tract electrocoagulation group than in the non-trans-tract electrocoagulation group. Patients experienced a higher nephrostomy tube-free rate (67% vs 26%, P < 0.0001), shorter postoperative catheterization time (2.8 ± 3.8 vs 5.4 ± 5.0 days, P = 0.002) and shorter hospital stay (6.5 ± 3.6 vs 8.8 ± 5.0 days, P = 0.0001) in the trans-tract electrocoagulation group than in the non-trans-tract electrocoagulation group. CONCLUSIONS: Trans-tract electrocoagulation in endoscopic combined intrarenal surgery is a safe and efficient procedure that decreases the need for nephrostomy tube placement after surgery.

Renal Denervation in Isolated Systolic Hypertension Using Different Catheter Techniques and Technologies.

Patients with isolated systolic hypertension (ISH) are thought to show a diminished blood pressure (BP)-lowering effect after renal sympathetic denervation (RDN). This conclusion is mostly derived from unipolar radiofrequency catheter ablation studies. Limited data for newer RDN technologies exist. We used data from the RADIOSOUND-HTN (Three-Arm Randomized Trial of Different Renal Denervation Devices and Techniques in Patients With Resistant Hypertension) comparing 3 different RDN approaches to investigate a possible interaction between ISH and RDN response. One hundred twenty patients were stratified by having ISH or combined systolic-diastolic hypertension (CH). Of these, 39 underwent radiofrequency ablation of the renal main arteries, 39 combined radiofrequency ablation of the main and branch arteries, and 42 were treated with ultrasound-based ablation of the main renal artery. Patients with ISH (n=61) were older and had lower systolic and diastolic BP on ambulatory measurement (ambulatory BP measurement) at baseline in comparison to CH (n=59). At 3 months, patients with ISH showed a less pronounced BP-lowering effect of RDN as compared to patients with CH (daytime average -5.9±11.8 versus -13.3±11.7 mm Hg, P=0.001). This difference was significant for radiofrequency ablation of the renal main arteries and ultrasound-based ablation of the main renal artery treatment but did not reach significance in the radiofrequency ablation of the main and branch arteries group. After adjustment for baseline BP values and age, there was no significant difference in BP reduction between ISH and CH. Using unadjusted BP values, RDN seems to be more effective in CH than in ISH. However, adjusting for baseline BP values revealed similar BP reduction in ISH and CH patients, irrespective of the RDN treatment used. The value of ISH as predictor for successful RDN might have been overestimated in the past. Clinical Trial Registration- URL: http://www.clinicaltrials.gov . Unique identifier: NCT02920034.

Interest of cervical ripening using double balloon catheters for labour induction in term nulliparous women.

OBJECTIVE: To compare the efficiency of double balloon catheters with that of intravaginal prostaglandins alone for the labor induction of unfavourable cervices in term nulliparous women. METHODS: 50 nulliparous patients induced with a double balloon device were compared to 53 patients induced using intravaginal prostaglandins alone. The main outcome measure was labour induction failure, characterized by the absence of active labour. The secondary outcome measures were the improvement of the Bishop score, the average durations of ripening and labour induction, the average time to active labour, the need for a second cervical ripening agent, the total dose of prostaglandins used in each group, the use of oxytocins, as well as the rates of vaginal delivery, abnormal foetal heart rate during labour and perinatal maternal infection. RESULTS: The rate of failed labour induction was of 28% in the double balloon group, against 13% in the prostaglandins group. The average durations of ripening and labour induction, as well as the time to active labour were higher in the double balloon group. The improvement of the Bishop score was significantly lower in the double balloon group. DISCUSSION AND CONCLUSION: In our study, the use of double balloon catheters does not seem to reduce the rate of failed labour induction in nulliparous women when compared to the use of prostaglandins alone. In addition, it could lengthen the labour induction duration, although more powerful studies would be necessary not to recommend its use for nulliparous women.

Direct cost of peripheral catheterization by nurses.

OBJECTIVE: To measure the average direct cost of peripherally inserted central catheterization performed by nurses in a pediatric and neonatal intensive care unit. METHOD: A quantitative, exploratory-descriptive, single-case study, whose sample consisted of the non-participant observation of 101 peripherally inserted central catheter procedures. The cost was calculated by multiplying the execution time (timed using a chronometer) spent by nursing professionals, participants in the procedure, by the unit cost of direct labor, added to the cost of materials, drugs, and solutions. RESULTS: The average direct cost of the procedure was US$ 326.95 (standard deviation = US$ 84.47), ranging from US$ 99.03 to US$ 530.71, with a median of US$ 326.17. It was impacted by material costs and the direct labor of the nurses. CONCLUSION: The measurement of the average direct cost of the peripherally inserted central catheter procedure shed light on the financials of consumed resources, indicating possibilities of intervention aiming to increase efficiency in allocating these resources.

Intravenous catheter-related adverse events exceed drug-related adverse events in outpatient parenteral antimicrobial therapy.

BACKGROUND: Drug-related adverse events (AEs) are reported to be common amongst patients receiving outpatient parenteral antimicrobial therapy (OPAT). However, comparative data regarding intravenous (iv) catheter-related AEs are lacking. OBJECTIVES: To compare drug- and iv catheter-related AEs from a large UK OPAT centre. PATIENTS AND METHODS: We reviewed 544 OPAT episodes [median (IQR) age: 57 (39-71) years, 60% male, 13% with diabetes] with a median (IQR) duration of 7 (2-18) days. Clinically significant drug- and iv catheter-related AEs were calculated as a percentage of OPAT episodes with an AE and also as AEs per 1000 iv drug/catheter days. RESULTS: Drug-related AEs complicated 13 (2.4%) OPAT episodes at 1.7 (95% CI 0.9-2.9) per 1000 drug days. Catheter-related AEs occurred more frequently, complicating 32 (5.9%) episodes at 5.7 (95% CI 4.2-7.9) per 1000 iv catheter days (χ2 test for difference in AE rate: P < 0.001). Non-radiologically guided midline catheters were associated with the most frequent AEs (n = 23) at 15.6 (95% CI 10.3-23.4) per 1000 iv catheter days compared with other types of iv catheters (HR 8.4, 95% CI 2.4-51.9, P < 0.004), and self-administration was associated with a higher rate of catheter-related AEs at 12.0 (95% CI 6.0-23.9) per 1000 iv catheter days (HR 4.15, 95% CI 1.7-9.1, P = 0.007). CONCLUSIONS: Clinically significant iv catheter-related AEs occurred more frequently than drug-related AEs, especially when using non-radiologically guided midline catheters. Regular review of the need for iv therapy and switching to oral antimicrobials when appropriate is likely to minimize OPAT-related AEs.

Double-balloon catheter versus dinoprostone insert for labour induction: a meta-analysis.

OBJECTIVE: To assess the efficacy and safety of a double-balloon catheter versus dinoprostone insert for labour induction. STUDY DESIGN: PubMed, MEDLINE, Embase, ClinicalTrials.gov, and the Cochrane Central Register of Clinical Trials databases were searched from 1985 to April 2018. Randomized controlled trials that compared a double-balloon catheter and dinoprostone insert for cervical ripening were identified. Eligible study populations consisted of women with singleton pregnancies that had any indication for labour induction and were randomly assigned to undergo induction with a double-balloon catheter or dinoprostone insert. The main outcomes were incidence of vaginal delivery within 24 h and caesarean section, and neonatal outcomes. RESULTS: Five randomized trials (603 women; 305 with a double-balloon catheter and 298 with a dinoprostone insert) were eligible for inclusion. No differences were observed between the two groups in terms of vaginal delivery within 24 h [relative risk (RR) 1.21, 95% confidence interval (CI) 0.93-1.59] and incidence of caesarean section (RR 0.99, 95% CI 0.77-1.27). Compared with the double-balloon catheter, the dinoprostone insert was associated with a reduced need for oxytocin administration in the process of labour induction (RR 1.95, 95% CI 1.45-2.62). However, there was a higher incidence of excessive uterine activity (RR 0.17, 95% CI 0.06-0.54) and neonatal umbilical cord arterial blood pH < 7.1 (RR 0.36, 95% CI 0.15-0.84) in the dinoprostone insert group. CONCLUSION: This review showed that the efficacy of labour induction using both the double-balloon catheter and dinoprostone insert was similar. However, the double-balloon catheter seemed to be a safer method.

Prospective randomized comparative study of pigtail catheter drainage versus percutaneous needle aspiration in treatment of liver abscess.

BACKGROUND: This prospective randomized comparative study is designed to compare outcomes of ultrasonography-guided pigtail catheter drainage (PCD) and needle aspiration for the treatment of liver abscesses in terms of days to achieve clinical improvement, 50% reduction in cavity size and duration of hospital stay. METHODS: This is a hospital-based comparative study conducted in SMS Hospital, Jaipur, India, from May 2015 to May 2017. Sample size was calculated to be 95 subjects in each of the two groups at α error of 0.05 and power of 80%. Independent t-test was used for statistical analysis. RESULTS: A total of 190 patients of liver abscess were included in this study and we treated 95 patients with percutaneous needle aspiration (PNA) and remaining patients with PCD along with systemic antibiotics. Mean time for clinical improvement in PNA group (6.96 ± 1.33 days) was higher as compared to PCD group (4.22 ± 1.25 days). The mean time for reduction of cavity size to 50% of original size in PNA group (7.05 ± 1.25 days) was higher as compared to PCD group (4.43 ± 1.27 days). Mean hospital stay of patients in PNA group (12.9 ± 4.02 days) was higher as compared to PCD group (11.44 ± 4.15 days). CONCLUSION: Percutaneous catheter drainage is a better modality as compared to PNA especially in larger abscesses which are partially liquefied.

Enhanced recovery care versus traditional care following laminoplasty: A retrospective case-cohort study.

Enhanced recovery after surgery (ERAS) has been shown to shorten length of hospital stay and reduce perioperative complications in many types of surgeries. However, there has been a paucity of research examining the application of ERAS to major spinal surgery. The current study was performed to compare complications and hospital stay after laminoplasty between an ERAS group and a traditional care group.The ERAS group included 114 patients who underwent laminoplasty managed with an ERAS protocol between January 2016 and June 2017. The traditional care group included 110 patients, who received traditional perioperative care between November 2014 and December 2015. Postoperative hospital stay (POPH), physiological function, postoperative visual analogue scale (VAS) pain score, and postoperative complications were compared between the 2 groups.The mean POPH was significantly shorter in the ERAS group than traditional care group (5.75 ±â€Š2.46 vs. 7.67 ±â€Š3.45 d, P < .001). ERAS protocol significantly promoted postoperative early food-taking (8.45 ±â€Š2.94 h vs 21.64 ±â€Š2.66 h, P < .001), reduced the first time of assisted walking (30.79 ±â€Š14.45 vs. 65.24 ±â€Š25.34 h, P < .001), postoperative time of indwelling urinary catheters (24.76 ±â€Š12.34 vs. 53.61 ±â€Š18.16 h, P < .001), and wound drainage catheters (43.92 ±â€Š7.14 vs. 48.85 ±â€Š10.10 h, P < .001), as compared with the traditional care group. Pain control was better in the ERAS group than traditional care group in terms of mean VAS score (2.72 ±â€Š0.46 vs. 3.35 ±â€Š0.46, P < .001) and mean maximum VAS score (3.76 ±â€Š1.12 vs. 4.35 ±â€Š1.15, P < .001) in 3 days after surgery. The morbidity rate was 21.05% (24 of 114 patients) in the ERAS group and 20.90% (23 of 110 patients) in the control group (P = .75).The ERAS protocol is both safe and feasible for patients undergoing laminoplasty, and can decrease the length of postoperative hospitalization without increasing the risk of complications.

Surgical Techniques for Catheter Placement and 5/6 Nephrectomy in Murine Models of Peritoneal Dialysis.

Peritoneal dialysis (PD) is a renal replacement therapy consistent on the administration and posterior recovery of a hyperosmotic fluid in the peritoneal cavity to drain water and toxic metabolites that functionally-insufficient kidneys are not able to eliminate. Unfortunately, this procedure deteriorates the peritoneum. Tissue damage triggers the onset of inflammation to heal the injury. If the injury persists and inflammation becomes chronic, it may lead to fibrosis, which is a common occurrence in many diseases. In PD, chronic inflammation and fibrosis, along with other specific processes related to these ones, lead to ultrafiltration capacity deterioration, which means the failure and subsequent cessation of the technique. Working with human samples provides information about this deterioration but presents technical and ethical limitations to obtain biopsies. Animal models are essential to study this deterioration since they overcome these shortcomings. A chronic mouse infusion model was developed in 2008, which benefits from the wide range of genetically modified mice, opening up the possibility of studying the mechanisms involved. This model employs a customized device designed for mice, consisting of a catheter attached to an access port that is placed subcutaneously at the back of the animal. This procedure avoids continuous puncture of the peritoneum during long-term experiments, reducing infections and inflammation due to injections. Thanks to this model, peritoneal damage induced by chronic PD fluid exposure has been characterized and modulated. This technique allows the infusion of large volumes of fluids and could be used for the study of other diseases in which inoculation of drugs or other substances over extended periods of time is necessary. This article shows the method for the surgical placement of the catheter in mice. Moreover, it explains the procedure for a 5/6 nephrectomy to mimic the state of renal insufficiency present in PD patients.

Predicting the necessity of adding catheters to intracavitary brachytherapy for women undergoing definitive chemoradiation for locally advanced cervical cancer.

PURPOSE: To identify if baseline patient or magnetic resonance imaging (MRI) features can predict which women are at risk for inadequate tumor coverage with only intracavitary tandem and ovoid (T + O) brachytherapy and to correlate tumor coverage with clinical outcomes. METHODS AND MATERIALS: We performed a retrospective study of 50 women with cervical cancer treated with chemoradiation at a single institution between January 2014 and December 2015. All patients had a 3T-MRI performed at baseline (MRI1) and at the completion of external beam radiation therapy (MRI2). Gross tumor volume initial (GTV-Tinit) was measured on MRI1 and high-risk clinical tissue volume (CTVHR) on MRI2. CTVHR extending beyond point A was classified as too large for adequate coverage with T + O and requiring interstitial needles. Multivariate analysis was performed to determine predictive factors of inadequate coverage. Kaplan-Meier and Cox Regression were performed to correlate inadequate coverage with outcomes. RESULTS: Mean patient age was 49.2 ± 13.2 years, and 84% had Federation of Gynecology and Obstetrics IIB/IIIB disease. Forty-two percent of women were estimated to have inadequate tumor coverage with T + O brachytherapy. The GTV-Tinit volume and dimensions (superior-inferior, left-right, anterior-posterior) on MRI1 were all important predictive factors of inadequate coverage on multivariate analysis. Receiver operating characteristics curves identified optimal thresholds of superior-inferior ≥ 4.5 cm (area under the curve [AUC] = 0.718), left-right ≥ 4.5 cm (AUC = 0.745), anterior-posterior ≥ 5.0 cm (AUC = 0.767), and GTV-Tinit ≥ 85 cm3 (AUC = 0.842). Patients with inadequate coverage had worse clinical outcomes. CONCLUSIONS: Baseline MRI tumor size may predict inadequate CTVHR coverage at the time of brachytherapy (i.e., the need for interstitial needles). This may help identify a subset of women requiring early referral to adequately resourced centers to improve clinical outcomes.
