Randomized Controlled Trial Comparative Study
Comparison of local anesthetic effect of lidocaine by jet injection vs needle infiltration in lumbar puncture.
Usual routes of drug administration are often painful and invasive. Nowadays, using jet injection has been introduced successfully, as a noninvasive and painless method of anesthetic delivery in performing different procedures. ⋯ Injecting lidocaine by jet injector is less painful than infiltrating it by needle and syringe.

Randomized Controlled Trial
Effect of head position on the success rate of blind intubation using intubating supraglottic airway devices.
To evaluate the effect of head position on the performance of intubating supraglottic airway devices, we compared the success rate of blind intubation in the head-elevated and the pillowless head positions with the LMA Fastrach and the air-Q, and the change of glottic visualization through the air-Q. ⋯ Although the head-elevated position improved glottic visualization in the air-Q, the head position had minimal influence on the success rate of blind intubation with either the Fastrach or the air-Q.

American tackle football is the most popular high-energy impact sport in the United States, with approximately 9 million participants competing annually. Previous epidemiologic studies of football-related injuries have generally focused on specific geographic areas or pediatric age groups. Our study sought to examine patient characteristics and outcomes, including hospital charges, among athletes presenting for emergency department (ED) treatment of football-related injury across all age groups in a large nationally representative data set. ⋯ In this nationally representative sample, most ED-treated injuries associated with football were not acutely life threatening and very few required major therapeutic intervention. This study provides a cross-sectional overview of ED presentation for acute football-related injury across age groups at the population level in recent years. Longitudinal studies may be warranted to examine associations between the patterns of injury observed in this study and long-term outcomes among American tackle football players.

Syncope and collapse (=presyncope) are 2 symptoms of pulmonary embolism (PE), which are suspected of being connected with poorer outcome, regardless of haemodynamic instability. However, pathomechanisms are not completely understood. We aimed to investigate these pathomechanisms in regard to blood pressure and heart rate of syncope/collapse in PE. ⋯ The pathomechanism of syncope/collapse in patients with acute PE seems to be connected with blood pressure fall, heart rate increase and RVD, in terms of cardiovascular syncope with reduced cardiac output and vasovagal reflex.
