Suction catheter

BACKGROUND: We aimed to evaluate an approach to induced abortions during early pregnancies that controls the suction pressure and restricts the duration of the procedure. METHODS: Three hundred patients programmed for induced early pregnancy abortions, hospitalized in the Shandong Provincial Maternity & Child-care Hospital from October 2013 to October 2015, were enrolled. Patients were randomly assigned to either research or control group. In the research group, operation pressure was controlled at 400 mmHg and operation time in the uterine cavity was kept at less than 75 s...

INTRODUCTION: Negative Pressure Wound Therapy (NPWT) has proven to be a powerful tool in facilitating healing of difficult wounds of a variety of etiologies. The pediatric experience with NPWT has been limited due to concerns about vascular compression and pain associated with treatment. METHOD: A retrospective review was performed to evaluate the therapeutic effect of NPWT on children with difficult wounds due to burns or soft-tissue trauma. NPWT was instituted in the operating room under general anesthesia using a commercially available system...

OBJECTIVES: The need for a central venous catheter has limited the widespread use of ultrafiltration in daily clinical practice for the treatment of acute heart failure (AHF) with overt fluid overload. We evaluated the feasibility of a new ultrafiltration device, the CHIARA (Congestive Heart Impairment Advanced Removal Approach) system, that utilizes a single-lumen cannula (17G, multi-hole) inserted in a peripheral vein of the arm. METHODS: In this multicenter, prospective, feasibility study, consecutive ultrafiltration treatments (lasting ≥6 hours and with an ultrafiltration rate ≥100ml/h) with the CHIARA device and a single peripheral venous approach were performed at 6 Italian hospitals...

INTRODUCTION: Closed suctioning is commonly used in the context of high-setting mechanical ventilation (MV), given its ability to prevent lung volume loss that otherwise accompanies open suctioning. However, closed suctioning systems (CSS) are not equivalent regarding components and capabilities, and thus this technique may be differentially effective to adequately clear patient secretions from an endotracheal tube (ETT), which is of paramount importance when the tube size makes the ETT particularly vulnerable to block by patient secretions...

BACKGROUND: Esophageal ulceration and fistula are complications of pulmonary vein isolation using thermal energy sources. Irreversible electroporation is a novel, nonthermal ablation modality for pulmonary vein isolation. A single 200 J application can create deep myocardial lesions. Acute and chronic effects of this new energy source on the esophagus are unknown. METHODS AND RESULTS: In 8 pigs (±70 kg), the suprasternal esophagus was surgically exposed. A linear suction device with a single 35-mm long and 6-mm wide protruding linear electrode inside a plastic suction cup was used for ablation...

BACKGROUND: Oro/nasopharyngeal suction is a method used to clear secretions from the oropharynx and nasopharynx through the application of negative pressure via a suction catheter or bulb syringe. Traditionally, airway oro/nasopharyngeal suction at birth has been used routinely to remove fluid rapidly from the oropharynx and nasopharynx in vigorous and non-vigorous infants at birth. Concerns relating to the reported adverse effects of oro/nasopharyngeal suctioning led to a practice review and routine oro/nasopharyngeal suctioning is no longer recommended for vigorous infants...

Historical innovations in mechanical thrombectomy devices and strategies for ischemic stroke have resulted in improved angiographic outcomes and better clinical outcomes. Various devices have been used, but the two most common approaches are aspiration thrombectomy and stent-retrieval thrombectomy. Aspiration thrombectomy has advanced from the traditional Penumbra system to forced arterial suction thrombectomy and a direct aspiration first-pass technique. Newer generation aspiration catheters with flexible distal tips and a larger bore have demonstrated faster and better recanalization relative to older devices...

Cavoatrial deep venous thrombosis (DVT) is diagnosed with increasing prevalence. It can be managed medically with anticoagulation or with directed interventions aimed to efficiently reduce the thrombus burden within the target venous segment. The type of management chosen depends greatly on the etiology and chronicity of the thrombosis, existing patient comorbidities, and the patient's tolerance to anticoagulants and thrombolytic agents. In addition to traditional percutaneous catheter-based pharmacomechanical thrombolysis, other catheter-based suction thrombectomy techniques have emerged in recent years...

OBJECTIVE: To introduce an emerging technique termed 'super-mini- percutaneous nephrolithotomy' (SMP) and describe its application in practice. METHODS: We described the technique of SMP in the treatment of renal stones with emphasis on the material, indications, technique procedure, advantages, and results. RESULTS: SMP refers to a 7 Ch. nephroscope placed through a 10-14 Ch. metal access sheath with functions of both irrigation and suction-evacuation, to achieve stone fragmentation via laser or pneumatic lithotripsy...

Health-care materials associated with infections are very common in hospital admitted patients. There are generally infected by contact with the catheter or other multipurpose devices which are contacted with microbes. The respiratory infections associated with the pathogens having strong biofilm forming ability on catheter surface, causes life-threatening in every year. Therefore, a catheter coating material is of great interest which inhibits the biofilm formation of pathogens on a catheter to prevent respiratory infections...

AIMS: Percutaneous structural heart therapies, such as mitral value repair, require site-specific transseptal access (TSA). This can be challenging for interventional cardiologists. We describe a TSA catheter (TSAC) that utilises suction for enhanced control and puncture accuracy. Here, we aim to evaluate the safety and efficacy of the device. METHODS AND RESULTS: Ex vivo interatrial septum preparations were dissected from swine (n=8) and diseased human hearts (n=6) to quantify TSAC suction and needle puncture force...

Bladder neck (BN) dissection is considered one of the most challenging steps during robot-assisted radical prostatectomy. Better understanding of the BN anatomy, coupled with a standardized approach may facilitate dissection while minimizing complications. We describe in this article the 4 anatomic spaces during standardized BN dissection, as well other technical maneuvers of managing difficult scenarios including treatment of a large median lobe or patients with previous transurethral resection of the prostate...

It is difficult to treat large internal carotid aneurysms with simple surgical clipping. Here, we present a retrograde suction decompression (RSD) procedure for large internal carotid aneurysms using a balloon guide catheter combined with a blood-returning circuit and a superficial temporal artery to middle cerebral artery (STA-MCA) bypass.All patients underwent an STA-MCA bypass before the temporary occlusion of the internal carotid artery (ICA). A 6-French sheath was inserted into the common carotid artery (CCA), and a 6-French Patrive balloon catheter was placed into the ICA 5 cm past the bifurcation...

Air embolism is often an iatrogenic complication which may occur in venous or arterial circulation depending on the port of entry. We present two cases in which air embolism occurred in venous and arterial circulation after contrast medium injection (CMI) and coronary artery bypass graft (CABG) surgery, respectively. In one case, accumulation of air bubbles was observed in the pulmonary artery after CMI. This was attributed to inadvertent injection of air owing to improper connection of the injector and the catheter...

AIM: The feasibility of videoscopic inguinal-iliac-obturator lymphadenectomy (VIIOL) was assessed in 20 patients with melanoma and compared with a retrospective sample of 24 patients undergoing standard 'open' technique (IIOL). RESULTS: No postoperative death occurred; the mean operative time was lower in the IIOL series (190 min vs. 302 min) but the quality of life was greatly improved in the VIIOL group thanks to earlier bladder catheter removal, no nasogastric suction, less pain, earlier mobilization, lower in-hospital stay, and earlier resumption of daily activities (27...

BACKGROUND: Although the use of temporary shunts in proximal extremity amputations has been reported, no study has described the use of temporary shunts in distal extremity amputations that require vein grafting. Moreover, the total volume of blood loss when temporary shunts are used has not been reported. The aim of this study was to investigate the applicability of a temporary shunt for distal extremity amputations requiring repair by vessel grafting with an ischemia time of >6 hours...
