Imprinting

Imprinting

Behavioral imprinting is observed in some newborn animals and occurs when they develop strong and specific attachments to another animal (usually a parent) following brief, early-life exposures. Offspring imprint onto parents within a brief period after birth or hatching; this time window is called the critical period. Once imprinting occurs, the bond established between the parents and their offspring is usually long-lasting.

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Nursing Implementation

Nursing Implementation

Implementation is the execution of the nursing care plan developed during the planning phase.
The five steps to implementing effective nursing care include reassessing the patient, reviewing and revising the existing nursing care plan, organizing the resources and care delivery, anticipating and preventing complications, and implementing nursing interventions.

Drug Dosing: Infants and Children

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Summary

Weaning centers may improve outcomes for patients needing mechanical ventilation. More UK-based research is needed to confirm if these specialized units are cost-effective and enhance patient recovery.

Area of Science:

Critical Care Medicine
Health Services Research
Respiratory Therapy

Background:

Over 5% of UK critical care beds are occupied by patients weaning from mechanical ventilation.
North American diagnosis related groups (DRGs) spurred the development of cost-effective regional weaning centers.
The UK's upcoming Payment By Results system may drive similar initiatives.

Purpose of the Study:

To review the evidence for weaning centers.
To present organizational and outcome data from two North American weaning centers.
To compare North American weaning centers with UK critical care units.

Main Methods:

Review of existing literature on weaning centers.
Analysis of organizational data (nurse:patient ratios, ancillary staff) from two North American centers.
Comparison of outcomes for ventilator-dependent patients in weaning centers versus standard critical care.

Main Results:

North American weaning centers differ significantly from UK critical care units in staffing.
Limited data suggest potential outcome benefits for ventilator-dependent patients in weaning centers.
Evidence is inconclusive, indicating a need for further investigation.

Conclusions:

Weaning centers show promise for improving outcomes in ventilator-dependent patients.
Organizational differences, particularly staffing, may influence effectiveness.
UK-based studies are essential to evaluate the efficacy and cost-effectiveness of weaning centers in the UK context.
