Routes of Persuasion

Routes of Persuasion

Persuasion is the process of changing our attitude toward something based on some kind of communication. Much of the persuasion we experience comes from outside forces. How do people convince others to change their attitudes, beliefs, and behaviors? What communications do you receive that attempt to persuade you to change your attitudes, beliefs, and behaviors?

Peritoneal Dialysis II: Peritoneal Dialysis Systems and Complications

Peritoneal dialysis (PD) is a medical process that removes waste products and excess fluid from the body using the peritoneal membrane as a natural filter.Peritoneal Dialysis MethodsSeveral methods can be used for peritoneal dialysis, including Acute Intermittent Peritoneal Dialysis, Continuous Ambulatory Peritoneal Dialysis, and Automated Peritoneal Dialysis, also known as Continuous Cyclic Peritoneal Dialysis.Acute Intermittent Peritoneal Dialysis (AIPD) is used for patients with uremic...

Routes of Drug Administration: Parenteral

Routes of Drug Administration: Parenteral

The administration of drugs via parenteral routes allows for direct drug introduction into the systemic circulation, resulting in high bioavailability because the medication bypasses the harsh conditions of the gastrointestinal tract and hepatic metabolism.
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...

Routes of Drug Administration: Overview

Routes of Drug Administration: Overview

Drug administration involves delivering drugs to the body through various routes, such as enteral, parenteral, and topical.
Enteral administration refers to drugs absorbed through the gastrointestinal tract. They can be swallowed (perorally), placed under the tongue (sublingually), or on the inner lining of the cheeks (buccally). Perorally administered drugs take time to be absorbed and have a slower onset of action. The rectal route is another form of enteral administration, which allows for...

Drug Delivery: Enteral Route

Drug Delivery: Enteral Route

The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.

Drug Delivery: Parenteral Route

Drug Delivery: Parenteral Route

The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...

Area of Science:

Nephrology
Cardiology
Internal Medicine

Background:

Diuretics are standard for refractory heart failure but often lead to diuretic resistance and electrolyte imbalances.
Peritoneal ultrafiltration presents a potential alternative for managing fluid overload and improving outcomes in these patients.

Purpose of the Study:

To evaluate the efficacy of peritoneal ultrafiltration in refractory heart failure patients.
To assess changes in functional status, renal parameters, left ventricular ejection fraction, hospitalization duration, and myocardial depressant factors.

Main Methods:

Prospective observational study in a tertiary care hospital's Nephrology Department.
30 patients with refractory heart failure underwent peritoneal ultrafiltration.
Data collected at baseline and 6 months post-intervention.

Main Results:

Significant improvement in New York Heart Association (NYHA) functional status (Class IV to III/IV, P < 0.001).
Marked reduction in hospital stay (75.8 to 7.8 days, P > 0.001).
Improvement in serum creatinine (3.18 to 2.16 mg/dl, P < 0.001) and left ventricular ejection fraction (29.3% to 48.5%, P < 0.0001).
Reduction in myocardial depressant factors (IL-1, IL-6, TNF alpha).

Conclusions:

Peritoneal ultrafiltration is an effective alternative for symptomatic chronic heart failure patients resistant to maximal medical therapy.
This approach can improve quality of life and reduce healthcare utilization.
