What is an Experiment?

17.8K
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

Thomson's e/m Experiment

6.7K
In a beam of charged particles created by a heated cathode, the particles move at different speeds. However, many applications need a beam with uniform particle speeds. An arrangement known as a velocity selector uses electric and magnetic fields to pick particles with a particular speed from the beam.
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The magnetic...

Controls in Experiments

16.8K
When conducting an experiment, it is crucial to have control to reduce bias and accurately measure the dependent variables. It also marks the results more reliable. Controls are elements in an experiment that have the same characteristics as the treatment groups but are not affected by the independent variable. By sorting these data into control and experimental conditions, the relationship between the dependent and independent variables can be drawn. A randomized experiment always includes a...

Randomized Experiments

The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Crossover Experiments

Crossover experiments, also called the repeated-measurements design, is a study design in which all experimental units are exposed to all treatments in different periods. Crossover experiments are generally used in psychology, the pharmaceutical industry, agriculture, and medicine.
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.

Summary
This summary is machine-generated.

Decompressive craniectomy (DC) can lead to hydrocephalus, particularly with lower Glasgow coma scores and larger craniectomy size. Shunt surgery before cranioplasty may prevent complications like hydrocephalus and epidural hygromas.

Area of Science:

  • Neurosurgery
  • Neurology
  • Critical Care Medicine

Background:

  • Decompressive craniectomy (DC) is a critical intervention for severe traumatic brain injury and cerebrovascular events.
  • Post-DC complications, including hydrocephalus and epidural hygromas, require careful management and can impact patient outcomes.

Purpose of the Study:

  • To investigate complications following decompressive craniectomy (DC) in patients with trauma or cerebrovascular disease.
  • To identify factors associated with ventriculomegaly and epidural hygromas post-DC.
  • To determine optimal treatment protocols for managing these complications.

Main Methods:

  • Retrospective analysis of clinical, radiological, and surgical data from 32 patients who underwent DC.
  • Recording of favorable and unfavorable outcomes, including the occurrence of ventriculomegaly and epidural hygromas.
  • Statistical analysis to identify associations between pre-operative/surgical factors and post-operative complications.

Main Results:

  • Ventriculomegaly was observed in 28.1% of patients post-DC, with 44.4% requiring shunt surgery.
  • Cranioplasty led to epidural hygromas in 44.8% of patients, necessitating surgery in some cases.
  • Lower Glasgow Coma Scale (GCS) scores, delayed cranioplasty, greater midline shift, and larger craniectomy size were significantly associated with ventriculomegaly.

Conclusions:

  • Lower GCS, delayed cranioplasty, increased midline shift, and larger craniectomy size are risk factors for hydrocephalus after DC.
  • Performing shunt surgery before cranioplasty, potentially in a single procedure, may help prevent hydrocephalus.
  • Epidural hygromas are common after cranioplasty and require careful monitoring and management.
