Randomized Controlled Trial Comparative Study
A randomized controlled trial comparing minichest tube and needle aspiration in outpatient management of primary spontaneous pneumothorax.
The aim of this study was to compare outcomes and complications associated with needle aspiration (NA) and minichest tube (MCT) insertion with Heimlich valve attachment in the treatment of primary spontaneous pneumothorax at an emergency department (ED). ⋯ Both MCT and NA allowed safe management of primary spontaneous pneumothorax in the outpatient setting.

Randomized Controlled Trial
High doses of warfarin are more beneficial than its low doses in patients with deep vein thrombosis.
The efficacy and safety of enoxaparin in outpatient treatment of deep vein thrombosis have been well studied. The present study aimed to compare the efficacy of a 10-mg loading dose of warfarin with 5 mg of the drug and enoxaparin in achieving the international normalized ratio (INR) range. ⋯ The 10-mg loading dose of warfarin induces the therapeutic range of INR earlier than the 5-mg dose without causing any significant difference in the side effects. More cases in the 10-mg group had INR levels higher than 3; the very dose, therefore, is recommended as the loading dose in cases of outpatients with deep vein thrombosis referring to the ED. Tight control of INR, after the third day of treatment, is also recommended in these cases.

Randomized Controlled Trial
Short- vs long-axis approach to ultrasound-guided peripheral intravenous access: a prospective randomized study.
The objective of the study was to determine if the short-axis approach and long-axis approach to ultrasound-guided peripheral intravenous access (USGPIV) differ in success rate, catheter insertion time, and number of needle sticks. ⋯ Short-axis USGPIV technique required less insertion time than the long-axis technique. Success rate was higher in the short-axis group, but this difference was not statistically significant. However, all of the failed IVs in the long axis were rescued successfully in short axis.
