Suction cannula (SC) is an important instrument for a neurosurgeon. Currently used suction control valves, kept in the sterile field, are controlled by the surgeon, for which he needs to leave the sur...
Seven SC with various diameters of their lumen and TH were used for the study. Suction pressures were measured with suction tip open, immersed in saline and TH open and closed. TH of 2 SC were made sm...
Pressure and diameter of ST or TH were related in opposite direction. As the diameter increases the pressure decreases. A strong negative association was observed between the diameter of TH and the pr...
TH diameter of SC is important to control suction pressure with any size of SC. One should use tear-drop type TH or appropriate diameter of the circular type of TH to contemplate safe microneurosurger...
The principles of chest drainage have not changed significantly since 1875 when Bülau introduced the idea of underwater drainage tube which became a trademark of thoracic surgery. We performed a prosp...
A multi-center, prospective, parallel group, randomized, controlled trial enrolling patients after thoracic procedures in which visceral pleura remained intact at the end of surgery between August 202...
During the study period, 111 patients were recruited. Eleven patients had negative Suction-seal test and were excluded by inserting a traditional underwater seal. The remaining 100 patients were rando...
The results of this study suggest that either omitting drain or inserting a low auto suction drain safely substitutes the one-way valve when the visceral pleura remains intact. Omitting drain or inser...
Suction pressure is one of the most important factors influencing the amount of tissue obtained during endoscopic ultrasound-guided fine-needle aspiration/biopsy (EUS-FNA/FNB). In this study we aimed ...
Different types of fine needles and suction techniques were used, including the slow pull technique (SPT), dry suction technique (DST), wet suction technique (WST), neutralizing negative pressure tech...
Actual suction pressure and weight of the suctioning liquid were lower using SPT than using DST, while they were higher when using WST compared with those using DST. In general, the actual suction pre...
WST is superior to SPT and DST in terms of actual suction pressure and weight of suctioning liquid. Diameter of the FNA needle was an important factor that may affect the actual suction pressure and w...
Surgery, by nature, involves blood loss. Thus, suction plays an important role in ensuring a clean operating view and ease of access. In ophthalmology, there is a void for an efficient and flexible su...
Blood loss is common during surgical procedures, especially in open cardiac surgery. Allogenic blood transfusion is associated with increased morbidity and mortality. Blood conservation programs in ca...
We evaluated magnetic resonance imaging (MRI) as a qualitative tool for detection of turbulence. MRI is sensitive to flow; this study uses velocity-compensated T1-weighted 3D MRI for turbulence detect...
Our standard control suction head Model A showed pronounced signs of turbulence at all flow rates measured, while turbulence was only detectable in our modified Models 1-3 at higher flow rates (Models...
The comparison of flow performance of surgical suction heads with different geometries via acceleration-sensitized 3D MRI revealed significant differences in turbulence development between our standar...
As the global community begins recovering from the COVID-19 pandemic, the challenges due to its aftermath remain. This health crisis has highlighted challenges associated with airborne pathogens and t...
This paper presents a novel suction device designed to counteract the spread of aerosols and droplets and be cost-effective and adaptable to diverse environments. We also conducted an experimental stu...
The device reduced airborne disease transmission risk, as evidenced by its capacity to decrease the half-life of aerosol volume from 23.6 minutes to 15.6 minutes, effectively capturing aerosol-sized d...
The experiment's findings confirm the suction device's capability to effectively remove droplets from the environment, making it a vital tool in enhancing indoor air quality. Given the sustained perfo...
To study the biometric modifications of the eyeball during suction in Laser assisted in Situ Keratomileusis (LASIK)....
Observational and cross-sectional study. We studied 43 patients who underwent surgery for myopia and myopic astigmatism. Mean age was 38.3 ± 11.5 years, and 19 were female (44.2%). Conventional LASIK ...
The mean spherical equivalent refractive error was -4.5 ± 2.3 diopters. During suction, the AQD did not change significantly (p = 0.231). However, AXL and VCL increased by 0.12 mm and 0.22 mm respecti...
Suction maneuvres during LASIK surgery produce changes of little magnitude in the eye globe, mainly a decrease in LT and an increase in VCL and AXL. Therefore, these modifications are expected to prod...
Dental procedures involving drilling and grinding can produce a significant amount of suspended aerosol particles (PM) and bioaerosols. This study aims to analyze the size and concentration of aerosol...
For this study, 100 extracted permanent teeth were collected and divided into three groups: without suction (n = 50), suction with forceful suction (n = 25), and suction with air disinfection machines...
When drilling and grinding were performed without vacuum, 0.75% of the aerosol particles generated were PM2.5-10, 78.25% of total suspended aerosol particles (TSP) were PM2.5, and 98.68% of TSP were P...
In conclusion, the air exchange system can reduce the aerosol particles generated during drilling and grinding. Comparing the two air exchange systems, it was found that the air disinfection machines ...
Epicardial ablation is an important approach in the management of patients with complex ventricular arrhythmias. Irrigated ablation catheters present a challenge in this potential space due to fluid a...
Consecutive patients undergoing epicardial ventricular tachycardia (VT) ablation at a single center were included. All patients underwent epicardial access via a subxiphoid approach with a single oper...
Eleven patients were included in this series. All patients underwent epicardial ablation with complete success achieved in 8 of the 11 patients and partial success in the remaining patients. Pericardi...
Dry suction water seal drainage systems can provide a safe strategy for efficient pericardial fluid management during epicardial VT ablation, potentially shortening procedure duration....
