Radiological Investigation III: Pulmonary Angiogram and PET Scan

147
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Burn Injuries

2.7K
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

Renal Failure: Dose Adjustments01:11

Renal Failure: Dose Adjustments

146
In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...

Summary
This summary is machine-generated.

Trace element deficiencies in major burns patients were not corrected by updated repletion strategies. A data entry error in the computerized information system led to lower copper and selenium levels, highlighting the need for quality control.

Area of Science:

  • Critical care medicine
  • Nutritional science
  • Burn management

Background:

  • Major burns cause acute deficiencies in trace elements like copper, selenium, and zinc due to wound exudate.
  • Trace element repletion strategies can reduce infectious and surgical complications in burn patients.
  • Recent adjustments to trace element dosing protocols did not yield expected improvements.

Purpose of the Study:

  • To investigate the reasons behind the failure of a revised trace element repletion strategy in major burn patients.
  • To identify potential errors in trace element dosing or administration.
  • To ensure optimal trace element levels for improved patient outcomes.

Main Methods:

  • A retrospective cohort study involving critically ill major burn patients (burns >20% BSA).
  • Patients were divided into two periods: pre-dose change (2011-2015) and post-dose change (2017-2020).
  • Data on demographics, daily trace element delivery, and weekly blood levels were extracted from the Computerized Information System (CIS).

Main Results:

  • No significant differences in age or burn severity (BSA) between the two study periods.
  • Patients in the later period (Period B) showed significantly lower blood levels of copper (p=0.046) and selenium (p=0.031).
  • A critical error was identified: trace element salts' weight was entered instead of elemental weight in molar units within the CIS.

Conclusions:

  • The revised trace element repletion doses since 2017 led to decreased blood levels of copper and selenium.
  • A CIS customization error involving salt versus elemental weight was the root cause of the underdosing.
  • Systematic quality control and adherence to standard international units are essential to prevent such errors.
