Transmission-based Precautions I: Contact, Enteric, and Droplets

Transmission-based Precautions I: Contact, Enteric, and Droplets

Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Endoscopic Studies II: Thoracocentesis

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...

Area of Science:

Radiology
Medical Physics
Diagnostic Imaging

Background:

Enteroclysis is a radiographic examination of the small intestine.
This procedure delivers considerable radiation dose to patients.
Optimizing radiation dose in diagnostic imaging is crucial for patient safety.

Purpose of the Study:

To evaluate patient radiation dose during enteroclysis using thermoluminescent dosemeters (TLDs).
To estimate thyroid surface dose (TSD) and doses to radiosensitive organs.
To establish a local diagnostic reference level for dose optimization.

Main Methods:

A total of 46 patients undergoing enteroclysis were examined.
Patients were divided into two groups based on the digital X-ray machine used.
Radiation doses were measured using TLDs, including entrance surface dose (ESD) and TSD.

Main Results:

The mean entrance surface dose (ESD) was 601.2 ± 96.2 mGy.
The mean fluoroscopy time was 8.5 ± 3 min, and the mean TSD was 0.34 ± 0.6 mGy.
Dose values were found to be higher than those reported in existing literature.

Conclusions:

A local diagnostic reference level was introduced to guide patient dose optimization.
Findings highlight the need for strategies to reduce radiation exposure during enteroclysis.
Further research may focus on comparing different imaging protocols and equipment.
