Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy

Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in...

Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

Acute Kidney Injury V: Interprofessional Care

Acute Kidney Injury V: Interprofessional Care

Acute Kidney Injury (AKI) requires a collaborative healthcare approach to restore renal function and prevent complications. Essential management strategies involve monitoring fluid and electrolyte balance, adjusting medications, initiating dialysis when necessary, and providing nutritional support.Fluid and Electrolyte ManagementFluid Monitoring: Regularly monitoring body weight, central venous pressure, and urine output helps detect fluid imbalances early. Patient intake and output are...

Dialysis

Dialysis

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

Summary

Cyclodialysis, a ciliary muscle tear causing low eye pressure, is often trauma-related. Ultrasound biomicroscopy (UBM) effectively diagnosed a subtle case missed by gonioscopy, enabling successful surgical treatment.

Area of Science:

Ophthalmology
Ocular Trauma
Diagnostic Imaging

Background:

Cyclodialysis involves ciliary muscle separation from scleral insertion, leading to ocular hypotony.
Traumatisms are the primary cause of cyclodialysis.
Traditional diagnosis via gonioscopy is increasingly supplemented by advanced imaging.

Observation:

A 57-year-old male experienced severe left eye trauma from a radial saw, resulting in corneal perforation and vitreous hemorrhage.
Despite persistent ocular hypotony, gonioscopy revealed normal findings.
Ultrasound biomicroscopy (UBM) identified a small cyclodialysis measuring less than ten degrees.

Findings:

UBM proved superior to gonioscopy in diagnosing subtle cyclodialysis post-trauma.
Early diagnosis of cyclodialysis is crucial for managing ocular hypotony.

Implications:

This case highlights UBM's value in diagnosing traumatic cyclodialysis when gonioscopy is inconclusive.
Prompt surgical intervention for cyclodialysis can restore normal intraocular pressure and visual function.
