Nebulized dexmedetomidine in the treatment of obstetric post-dural puncture headache: two case reports.

Post-dural puncture headache (PDPH) is a debilitating complication of neuraxial anesthesia, particularly prevalent in obstetric patients, usually characterized by a postural headache. PDPH is hypothesized to result from cerebrospinal fluid leakage through a dural puncture, triggering symptoms like neck stiffness and subjective hearing changes. While conservative measures are common for treatment, more refractory cases may require invasive interventions such as an epidural blood patch (EBP).

A 75-year-old patient with autosomal dominant polycystic kidney disease (ADPKD) and hypertension was admitted to the hospital with abdominal pain secondary to a choledochal cyst resulting in biliary dilation. His hospital course was complicated by pneumonia, encephalopathy, and lower gastrointestinal bleeding (LGIB) that initially did not lead to hemodynamic compromise. To further evaluate the LGIB, a colonoscopy was performed, during which he experienced significant hypotension after being placed in the supine position and given anesthesia.

Increased blood pressure upon standing is considered a cardiovascular risk factor. We investigated the reproducibility of changes in aortic blood pressure, heart rate, stroke volume, cardiac output, and systemic vascular resistance during three passive head-up tilts (HUT) in 223 participants without cardiovascular medications (mean age 46 years, BMI 28 kg/m2, 54% male). Median time gap between the first and the second HUT was 9 weeks and the second and the third HUT 4 weeks.

Intermittent negative pressure is an emerging treatment for lower limb vascular disease but the specific physiological effects, particularly upon large artery haemodynamics are unclear. This study examined the influence of intermittent negative pressure upon popliteal artery shear rate during both supine and sitting postures. Eleven healthy participants (5 female; age: 28.

Background: The efficiency and productivity of dentists are affected due to musculoskeletal disorders. Efforts should be made to monitor and reduce these disorders so that proper relation is maintained between body and work.
Aims And Objectives: This research evaluates and compares the level of creatine kinase (CK) in operators working in ergonomically correct posture and incorrect posture using a newly developed digitalized alarm sensor attached to a dental operating stool.
