背景瑞芬太尼可以减轻全麻苏醒期时的咳嗽、躁动和血流动力学变化等不良反应。方法在一项前瞻性、随机、双盲临床试验中，60例接受鼻部手术的成人患者采用以瑞芬太尼为基础的麻醉方案。在苏醒期，瑞芬太尼组患者将瑞芬太尼用量减至维持量的1／10，而对照组患者则停止使用。结果两组患者的苏醒时间和气管拔管时间无明显区别。与对照组相比，瑞芬太尼组在苏醒期（输注速率：0．014±0．011μg·kg·min^-1）的咳嗽发生率（40％vs80％，P=0．002）和严重程度均明显减轻，不自主运动发生率降低（3．3％vs30％，P=0．006），心率较慢。结论在苏醒期使用小剂量瑞芬太尼不会延长苏醒时间，且降低气管插管所致咳嗽的发生率和严重程度。

Effect of Single- versus Double-Layer Uterine Closure during Caesarean Section on Niche Formation and Menstrual Irregularity

引用

Open Journal of Obstetrics and gynecology 2024年第1期14卷 57-68页

作者： Mohamed Samy Esraa Hussein fouad ghoneimy Walid Hitler Department of Obstetrics and gynaecology Faculty of Medicine Ain Shams University Cairo Egypt

Background: The myometrium at the location of the CS (caesarean section) scars, also known as residual myometrium thickness (RMT), is larger after a double-layer uterine closure procedure than following a single-layer one. It may lessen the formation of a niche that is the myometrium’s disruption at the location of the scar of the uterus. gynecological manifestations, obstetric problems in a future pregnancy and birth, and maybe subfertility are linked to thin RMT and a niche. Objective: To ascertain if double-layer unlocked closure of the uterus is better than single-layer one in terms of post-menstrual spotting and niche development following a first CS. Patients and Methods: In this randomized clinical study, 287 patients were evaluated for qualifying. Of all eligible individuals, 57 patients were excluded from the study based on the inclusion criteria. Results: The variation in ages, gestational age, body mass index (BMI), and cesarean section indications between the two assigned groups is statistically insignificant. However, postmenstrual spotting was statistically significantly more common in single-layer group compared to in double-group. The current study revealed ultrasound findings suggestive of niche formation was statistically significantly more common in single-layer group compared to in double-layer group. Conclusion: As evident from the current study, it demonstrates the advantages of double-layer unlocked closure of the uterus over single-layer one in terms of post-menstrual spotting and niche development following first-time cs. Thus, we deduced that fewer niches are formed, and fewer menstrual spotting occurs in the presence of double unlocked layers closure. To ascertain the impact of uterus closure method on post-operative niche development and the risk of obstetrics and gynaecological problems, further prospective trials with extended follow-up periods are required.

International Journal of Astronomy and Astrophysics 2024年第3期14卷 220-229页

作者： SH. M. Shehata Ahmed M. fouad R. M. Samir A. A. Shaker National Research Institute of Astronomy and geophysics (NRIAg) Helwan Egypt

This study investigates the X-ray properties and evolution of Type II supernovae (SNe II) observed by Swift, examining variations among supernovae and exploring their X-ray characteristics over time. We present the first X-ray study of the Type IIp supernova SN 2008ij using data from the Swift X-ray mission. This investigation focuses on its spectral properties, identifying an X-ray flux of 1.20 (+0.11, −0.10) × 10−13 erg/cm2/s and a plasma temperature of 4.76 (+1.22, −0.83) keV. Our study marks an advancement in understanding SN 2008ij, providing crucial results into its X-ray emission characteristics. These results lay the groundwork for future studies of Type IIp supernovae, offering a foundation for exploring their evolutionary and physical processes.
