The objective was to evaluate if existence of hydrothorax in initial chest radiograph predicts treatment outcome in patients with primary spontaneous pneumothorax who received needle thoracostomy. ⋯ Hydropneumothorax, previous history of pneumothorax, and large size were independent predictors of failure of needle aspiration in treatment of primary spontaneous pneumothorax.

Bystander cardiopulmonary resuscitation (CPR) improves survival from out-of-hospital cardiac arrest, but rates and performance quality remain low. Although training laypeople is a primary educational goal, the optimal strategy is not well defined. This study aimed to determine whether a short training with real-time feedback was able to improve hands-only CPR among untrained citizens. ⋯ With a very brief training supported by hands-on instructor-led advice and visual feedback, naïve laypeople are able to perform good-quality CC-CPR. Simple instructions, feedback, and motivation were the key elements of this strategy, which could make feasible to train big numbers of citizens.

Ultrasound measurement of inferior vena cava collapse predicts propofol-induced hypotension.
Hypotension is a common side effect of propofol, but there are no reliable methods to determine which patients are at risk for significant propofol-induced hypotension (PIH). Ultrasound has been used to estimate volume status by visualization of inferior vena cava (IVC) collapse. This study explores whether IVC assessment by ultrasound can assist in predicting which patients may experience significant hypotension. ⋯ Patients with IVC-CI≥50% were more likely to develop significant hypotension from propofol. IVC ultrasound may be a useful tool to predict which patients are at increased risk for PIH.
