Suction catheter

Impella is a mechanical circulatory support device of a catheter-based intravascular microaxial pump for left ventricular support and unloading. However, nonclinical studies assessing the effects of the extended duration of left ventricular unloading on cardiac recovery are lacking. An animal model using Impella implanted with a less invasive procedure to enable long-term support is required. This study aimed to evaluate the feasibility of an animal model for long-term support with Impella 5.5 implanted through carotid artery access in sheep...

BACKGROUND: Hepatic artery infusion pump (HAIP) with floxuridine/dexamethasone and systemic chemotherapy is an established treatment regimen, which had been reported about converting 47% of patients with stage 4 colorectal liver metastasis from unresectable to resectable.1,2 To this effect, HAIP chemotherapy contributes to prolonged survival of many patients, which otherwise may not have other treatment options. Biliary sclerosis, however, is a known complication of the HAIP treatment, which occurs in approximately 5...

BACKGROUND: Endotracheal suctioning in intubated or tracheotomized critically ill patients is a daily task of various professional groups in intensive and emergency medicine; however, a German language summary of current evidence is lacking. OBJECTIVE: The aim is to develop a narrative overview of current evidence on endotracheal suctioning of intubated or tracheotomized patients in the clinical setting. MATERIAL AND METHODS: A literature search was conducted in the databases Cinahl, Cochrane Library, Livivo, and Medline via PubMed by nurses with an academic degree...

Background: Some experts recommend specific ventilator settings during nebulization for mechanically ventilated patients, such as inspiratory pause, high inspiratory to expiratory ratio, and so on. However, it is unclear whether those settings improve aerosol delivery. Thus, we aimed to evaluate the impact of ventilator settings on aerosol delivery during mechanical ventilation (MV). Methods: Salbutamol (5.0 mg/2.5 mL) was nebulized by a vibrating mesh nebulizer (VMN) in an adult MV model. VMN was placed at the inlet of humidifier and 15 cm away from the Y-piece of the inspiratory limb...

Thrombotic occlusions of large blood vessels are increasingly treated with catheter based mechanical approaches, one of the most prominent being to employ aspiration to extract clots through a hollow catheter lumen. A central technical challenge for aspiration catheters is to achieve sufficient suction force to overcome the resistance of clot material entering into the distal tip. In this study, we examine the feasibility of inducing cavitation within hollow cylindrical transducers with a view to ultimately using them to degrade the mechanical integrity of thrombus within the tip of an aspiration catheter...

INTRODUCTION: Assess how urine chemistry tests are impacted by collection using a female external urinary catheter employing wicking and suction, to assess this catheter's potential as an alternative to transurethral catheters for collecting urine samples from incontinent patients. METHODS: We obtained 50 random 40 mL refrigerated urine specimens from excess volume submitted to the Michigan Medicine Biochemical Laboratory. Specimens were split into a 10 mL "control" sample simulating voided urine, and a 30 mL paired "wicked" sample applied dropwise to and collected from a fresh PureWick system simulating collection from an incontinent patient...

BACKGROUND: Endotracheal suctioning (ETS) is one of the most frequently performed invasive procedures in intensive care units (ICUs). This audit was aimed at studying current practices and knowledge regarding ETS in the Indian critical care setup, with the background aim of raising awareness regarding correct practices as per current recommendations in critically ill patients. MATERIALS AND METHODS: After registering the trial with the clinical trial registry, India, a structured audit questionnaire containing 20 questions pertaining to ETS was distributed through electronic media among resident doctors working in the ICUs across India...

INTRODUCTION AND IMPORTANCE: Intratracheal tumors account for approximately 0.2 % of respiratory tumors, including primary and secondary tumors. Secondary tumors of the upper trachea are most commonly derived from advanced thyroid cancer. Surgical resection is currently the general curative modality for thyroid cancer with tracheal invasion. Patients with tracheal tumors invading and protruding into the lumen may have reduced oxygen reserve capacity, leading to a shorter safe window for general anesthesia induction...

OBJECTIVE: We sought to investigate how priming the tube between air versus air mixed with saline ex vivo influenced suction force. We examined how priming the tube influenced peak suction force and time to achieve peak suction force between both modalities. METHODS: Using a Dwyer Instruments (Dwyer Instruments Inc., Michigan City, IN, USA), INC Digitial Pressure Gauge, we were able to connect a .072 inch aspiration catheter to a rotating hemostatic valve and to aspiration tubing...

BACKGROUND: To test the reliability and safety of a newly invented technique for minimally invasive percutaneous nephrolithotomy, intelligent pressure-controlled minimally invasive percutaneous nephrolithotomy (IPC-MPCNL). METHODS: Eighteen kidneys of nine female pigs were randomly divided into three groups. Those in Groups A and B underwent IPC-MPCNL through the new system composed of a pressure-measuring MPCNL suctioning sheath and an irrigation and suctioning platform with pressure feedback control...

We present a case of acute dyspnea due to postoperative oral bleeding after tonsillectomy, wherein a blood clot obscured the laryngeal structures to such an extent that no recognizable structures could be identified. A larger-bore suction catheter without side holes proved necessary to solve the problem. The case illustrates how a gradually forming blood clot can remain asymptomatic until reaching a size where it poses an airway threat and highlights the necessity for readily available larger-bore suction devices without side holes...

OBJECTIVE: The objective of this study is to characterize bladder mucosal trauma associated with intermittent catheterization with conventional eyelet catheters (CECs) and to assess if a microhole zone catheter (MHZC) design concept reduces this adverse effect. MATERIALS AND METHODS: A porcine model was developed to reflect human catheterization and bladder drainage. Nine pigs were randomized for catheterization with CEC ( n  = 6) or MHZC ( n  = 3)...

OBJECTIVES: Cesarean scar pregnancy (CSP) is a rare dangerous condition with still no consensus on standard treatment. Suction curettage has been used as the first-line treatment for CSP with controversial outcomes. This study evaluates efficacy of ultrasound-guided suction curettage (UGSC) followed by cervical-isthmic placement of silicon semirigid three-way foley catheter. MATERIALS AND METHODS: This study included 24 women with CSP. Preoperative ultrasound study was conducted...

OBJECTIVE: To design, develop and validate a new tool, called NEUMOBACT, to evaluate critical care nurses' knowledge and skills in ventilator-associated pneumonia (VAP) and catheter-related bacteraemia (CRB) prevention through simulation scenarios involving central venous catheter (CVC), endotracheal suctioning (ETS) and mechanically ventilated patient care (PC) stations. BACKGROUND: Simulation-based training is an excellent way for nurses to learn prevention measures in VAP and CRB...

Although robotic rectal resections are now widely performed, there are few robotic suction tools that can be easily used by console surgeons. It can therefore be difficult to maintain a clear visual field in the pelvis when there is effusion and bleeding from either a highly advanced cancer or from preoperative cancer treatment. In this report, we introduce our unique surgical technique that uses a soft catheter with a small gauze ball attached, inserted through the assistant port. This simple and inexpensive "instrument" can be used by the console surgeon as a retractor as well as a reliable suction device to secure their view of the operative field in the pelvis...

BACKGROUND: Open respiratory secretion suctioning with a catheter causes pain and injuries to the tracheobronchial mucosa in intubated patients. Mechanical insufflation-exsufflation (MI-E) aims at dragging secretions proximally non-invasively by generating a high peak expiratory airflow. Nebulized hypertonic saline with hyaluronic acid (HS-HA) facilitates suctioning by hydration. We assessed the safety and tolerance of a single session of airway clearance with MI-E and HS-HA in critically ill intubated patients...
