Endoscopic Studies II: Thoracocentesis

Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
Intrauterine Drug Delivery Systems01:21

Intrauterine Drug Delivery Systems

Controlled-release systems for intravaginal and intrauterine drug delivery have been developed primarily for the administration of contraceptive steroid hormones. These delivery routes circumvent first-pass hepatic metabolism, thereby enhancing bioavailability and allowing for reduced systemic dosages compared to oral administration. Such approaches contribute to improved therapeutic efficacy and patient compliance, particularly in long-term contraceptive regimens.Intravaginal Drug Delivery...

Summary

The Peezy urine collection device did not reduce contamination rates in pregnant women compared to the standard clean catch method. This randomized trial found no significant difference in urine culture contamination between the two methods.

Area of Science:

  • Obstetrics and Gynecology
  • Infectious Diseases
  • Urology

Background:

  • Screening for asymptomatic bacteriuria in pregnancy is crucial to prevent complications like acute pyelonephritis.
  • The standard clean catch midstream urine collection method is prone to contamination, especially in patients with obesity.
  • The Peezy device, designed to minimize contamination, has not been previously studied in pregnant populations.

Purpose of the Study:

  • To compare urine culture contamination rates between the Peezy device and the standard clean catch method in pregnant women before 20 weeks' gestation.
  • To assess if the Peezy device's effectiveness in reducing contamination varies by body mass index (BMI).

Main Methods:

  • A randomized controlled trial involving adult English-speaking women undergoing prenatal care.
  • Participants were randomized to use either the Peezy device or the standard clean catch method for urine collection.
  • Intention-to-treat analysis was used to compare contamination rates, with stratification by BMI status.

Main Results:

  • The overall contamination rate was 61.3% for the standard clean catch group and 52.5% for the Peezy group.
  • No statistically significant difference in contamination rates was observed between the Peezy and clean catch groups (OR=0.7, 95% CI: 0.4-1.2, p=0.19).
  • Stratification by BMI did not reveal any significant difference in contamination rates between the groups.

Conclusions:

  • This study did not demonstrate a reduction in urine culture contamination rates using the Peezy device in pregnant women.
  • The findings suggest that the Peezy device may not be superior to the standard clean catch method for reducing contamination in this population.
  • Further research may be needed to explore alternative methods for improving urine sample quality in pregnant individuals.
