BACKGROUND: Keeping the operating field clean and visible is an important technique in neurosurgery. Continuous irrigation-suction (IS) of the surgical field is currently often done using devices available that are expensive and demand technical proficiency. We report a simple method of continuous ISusing widely available central venous catheter and controlled suction cannula. METHODS: We used a controlled suction cannula attached to a central suction system. Single lumen central venous catheter is passed through the key hole of a controlled suction cannula, which is connected to a continuous irrigation system...

We propose a mechanism of how stroke may be caused by thrombus aspiration during primary percutaneous coronary intervention (PPCI), and how it may be technique-dependent. Two recent meta-analyses report increased risk of stroke in patients undergoing routine thrombus aspiration during STEMI and the value of this technique has been controversial. The mechanism of stroke has not been fully explained. This case demonstrates 2 mechanisms by which aspiration might cause thrombus embolization. We recommend that if thrombus aspiration is performed during PPCI for STEMI, it should be done selectively and carefully...

BACKGROUND: Surgical clipping of paraclinoid aneurysm can be very difficult because strong adhesions may hinder the dissection of the perforators and surrounding anatomical structures from the aneurysm dome. We describe our experience with using retrograde suction decompression during the clipping of paraclinoid aneurysms and discuss the relative advantages and pitfalls. MATERIALS AND METHODS: This study included 23 patients with large and giant paraclinoid aneurysms who underwent surgical treatment consisting of direct clipping with suction decompression between March 2004 and August 2014...

OBJECTIVE Reservoirs integrated into hydrocephalus shunts are commonly used for the removal of CSF and for intra-ventricular pressure measurement. Pumping with the reservoir to diagnose shunt sufficiency is still a matter of controversy. The authors describe an improved flushing device and its characteristic features in vitro and in vivo. METHODS The flushing reservoir is constructed with a sapphire ball in a cage as a nonresistance valve to also enable the detection of distal occlusions. The most important reservoir parameters were investigated in vitro, simulating total and partial proximal and distal shunt occlusions...

BACKGROUND: Wave intensity analysis can distinguish proximal (propulsion) and distal (suction) influences on coronary blood flow and is purported to reflect myocardial performance and microvascular function. Quantifying the amplitude of the peak, backwards expansion wave (BEW) may have clinical utility. However, simultaneously acquired wave intensity analysis and left ventricular (LV) pressure-volume loop data, confirming the origin and effect of myocardial function on the BEW in humans, have not been previously reported...

BACKGROUND AND AIMS: EUS-guided FNA biopsy has been widely performed to aid in the diagnosis of submucosal tumors (SMTs). However, in cases of small tumors, the diagnostic yield of EUS-FNA is poor. Therefore, it is necessary to develop a new needle for the diagnosis. We developed a device with a new mechanism that we refer to as a drill needle aspiration biopsy (DNAB). The aim of this study was to evaluate the use of DNAB in resected gastric SMT specimens. METHODS: A drill needle with a sharp tip and wide ditch was inserted into a catheter for angiography...

BACKGROUND: The insertion of suction devices through endotracheal tubes (ETTs) increases airway resistance and the subsequent suctioning may reduce airway pressures and facilitate atelectasis. The aim of this study was to investigate how airway pressures and tidal volumes change when different combinations of suction equipment and ETT sizes are used, and to what extent unfavorable effects can be ameliorated by choice of ventilator settings. METHODS: A mechanical ventilator was connected to a lung model by ETTs of 9 mm, 8 mm or 7 mm internal diameter (ID) with a pressure transducer inserted distal to the ETT...

Hemostasis is a critical point in endoscopic sinus and skull base surgery. A variety of techniques are presently available for reducing intraoperative bleeding; however, several limitations of the classical instruments should be stated. For example, reaching bleeding points in an anatomically angled site with straightforward bipolar devices could be quite difficult. With the aim of solving this problem, we developed a simple system using a standard curved suction tube, a rubber catheter and a monopolar system...

BACKGROUND: Accumulation of secretions in the airways of patients with an endotracheal tube and mechanical ventilation will have serious consequences. One of the most common methods of airway clearance is endotracheal suctioning. In order to facilitate discharge of airway secretion resulting in promotion of gas exchange, chest physiotherapy techniques can be used at the time of expiration before suction. MATERIALS AND METHODS: In this clinical trial with a cross-over design, 50 mechanically ventilated patients admitted to intensive care units (ICUs) were randomly divided into two groups of thoracic squeezing...
