PurposeTo study the biometric modifications of the eyeball during suction in laser assisted in situ keratomileusis (LASIK).MethodsObservational 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 surgery with a manual microkeratome was performed. Before and during the suction maneuvre the following parameters were measured using an 11 MHz biometric probe: aqueous depth (AQD), lens thickness (LT), vitreous cavity length (VCL) and axial length (AXL). Paired t-test was used to compare the biometric measurements before and during suction.ResultsThe 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 respectively (p = 0.039 and <0.01) and LT decreased by 0.20 mm (p<0.01). AXL increased in 42% of the eyes and decreased in 16%, VCL increased in 70% of the eyes and decreased in 9%, and the LT was reduced in 67% of the eyes.ConclusionsSuction 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 produce minimal anatomic alterations. 相似文献

Suction devices are integral to the safe delivery of anaesthesia and critical care. They are involved in clearing and aspirating body fluids, blood and debris, as well as employed in scavenging waste gases and diathermy fumes, intraoperative cell salvage systems, and tertiary devices such as vacuum mattresses and specialized wound dressings. All suction devices require three essential components, namely a source of vacuum, a reservoir/collection vessel and suction tubing. Other components of a suction device include an on/off switch, a vacuum regulator, vacuum gauge, filters, an overflow safety trap, an overfill protection device in the collection vessel, and a catheter. Several different types of catheter are available for use in different clinical situations. Vacuum and flow are the main physical principles underlying suction devices. The source of vacuum may be a fixed centrally piped system or a portable device using electrical, pneumatic or manual power. Pneumatically powered suction devices utilize the Bernoulli principle and Venturi effect. The efficiency of each system depends upon principles of displacement, degree of negative pressure and time taken to reach this, the internal resistance of the suction apparatus and the viscosity of the material to be aspirated. 相似文献

目的研究取栓口形状、抽吸流量以及血流速度对旋切抽吸式取栓器血栓抽吸效果的影响,为旋切抽吸式取栓器的设计和优化提供理论支持。方法建立3种取栓口("L"、"8"和"0"型)模型,研究取栓口形状对取栓的影响;以"8"型取栓口为基础,设置不同抽吸流量(75、100、125、150 mL/min)以及不同血液入口流速(0~10 cm/s,间距为1 cm/s),分析抽吸流量和血液流速对取栓效果的影响。结果 "L"型取栓口无法均匀地抽吸血栓,"8"型与"0"型取栓口的取栓效果差别不大,但"8"型取栓口附壁血栓清除率优于"0"型取栓口。当抽吸流量大于100 mL/min时,继续增大抽吸流量对取栓效果的提升有限。当血液流速小于1 cm/s时,抽吸效果最佳;随着血流速度增加,取栓效果逐渐下降。结论取栓口的形状、抽吸流量以及血液流速对取栓效果影响明显。选择宽而短的取栓口形状设计、适当提高抽吸流量以及降低血液流速,对取栓效果的提升有显著影响。研究结果可为旋切抽吸式取栓器的优化设计作指导。 相似文献

Pressure injury often seriously affects the life quality of aged patients, especially the long-term bedridden casualties. Widely adopted by different disciplines, negative pressure suction has its role in pressure injury. Microskin implantation has been demonstrated powerful in increasing the expansion ratio of donor area-derived skin and accelerating wound healing by forming “skin islands”. The study was designed to evaluate the efficacy and safety of additional use of bedside microskin implantation in the palliative care of pressure injury of aged patients who cannot tolerate surgical treatment as a supplement for standard negative pressure suction. An open-label within-patient RCT was conducted in aged patients with pressure injury. Sixteen patients were enrolled. After granulation tissues formed, half of a pressure injury was randomised to receive the negative pressure suction as the control group, and the other half exposed to additional bedside microskin implantation as the experimental group. Efficacy was evaluated within 1 month after treatment, and the primary endpoints included the wound healing rate and pressure ulcer scale for healing (PUSH) scores. The secondary outcomes included survival rate of implanted microskin, pain intensity assessment, satisfaction surveys from patients or their family, and pressure ulcer healing complications. Sixteen patients completed the study. After 14 days of operation, 5.63 ± 1.78 out of 10 pieces of implanted microskin survived and formed neonatal epithelium. The wound healing rates of the control group and the experimental group at 1 month were (26.17 ± 9.03%) and (35.95 ± 16.02%), respectively (P < .01). The mean PUSH score before the surgery was 12.38 ± 2.23. At 1 month after surgery, the mean difference of PUSH score from baseline was 2.13 ± 0.96 in the control group and 2.81 ± 0.83 in the experimental group (P < .01). The treatment of microskin implantation did not cause additional pain or complications to the patients. Accompanied by a better ulcer status, the majority of patients or their guardians have a high degree of acceptance towards the microskin implantation. Bedside microskin implantation could accelerate wound healing with lower PUSH scores. As a complementary palliative treatment, supplementary microskin implantation is effective and well tolerated. 相似文献
