The Anchoring-and-Adjustment Heuristic01:25

The Anchoring-and-Adjustment Heuristic

7.8K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Adjusting a Traverse01:12

Adjusting a Traverse

390
In the site survey of a four-sided traverse, internal angles are essential to ensure geometric accuracy. The survey revealed that the sum of the measured internal angles was 359 degrees and 48 minutes, which is 12 minutes less than the expected 360 degrees. This discrepancy signals an error likely arising from measurement inaccuracies during the fieldwork.To rectify this error, the adjustment process involved distributing the 12-minute shortfall equally across the four internal angles. By...

General Anesthesia: Overview

715
Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

Stages of General Anesthesia

1.8K
Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

Renal Failure: Dose Adjustments01:11

Renal Failure: Dose Adjustments

501
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...

Position-effect Variegation02:32

Position-effect Variegation

7.1K
In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.

Summary

Patient positioning (seated vs. supine) during strabismus surgery under topical anesthesia did not significantly affect ocular deviation. Most patients achieved favorable outcomes three months post-surgery, indicating position is not a predictor of success.

Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Strabismus Surgery

Background:

  • Strabismus surgery often involves adjustable sutures under topical anesthesia.
  • Patient positioning in the operating room may influence ocular alignment.
  • Understanding position-related effects is crucial for optimizing surgical outcomes.

Purpose of the Study:

  • To compare ocular deviation in patients undergoing adjustable strabismus surgery.
  • To evaluate the impact of patient position (seated vs. supine) on ocular alignment.
  • To determine if intraoperative position affects surgical outcomes.

Main Methods:

  • Prospective observational study of 30 strabismus patients.
  • Adjustable strabismus surgery performed under topical anesthesia.
  • Ocular deviation measured in seated and supine positions, pre- and post-operatively.

Main Results:

  • No statistically significant difference in ocular deviation between seated and supine positions.
  • Mean deviation in supine position: 8 pd (distance), 7.26 pd (near).
  • Mean deviation in seated position: 8.13 pd (distance), 8.5 pd (near).
  • Favorable outcomes achieved in 70% of patients at 3 months, increasing to 83.33% post-operatively.

Conclusions:

  • Patient position (seated or supine) during surgery does not significantly alter intraoperative ocular deviation.
  • Adjustable strabismus surgery under topical anesthesia yields favorable outcomes in the majority of cases.
  • Intraoperative ocular deviation measurements are not predictive of long-term surgical success.
