Insights

This study found that intraocular pressure (IOP) in children remains clinically stable during general anesthesia with sevoflurane, regardless of face mask use or laryngeal mask airway insertion.

Area of Science:

  • Anesthesiology
  • Ophthalmology
  • Pediatric Care

Background:

  • Intraocular pressure (IOP) management is crucial during pediatric anesthesia.
  • Sevoflurane is a common anesthetic agent used in children.
  • The impact of airway management on IOP requires further investigation.

Purpose of the Study:

  • To compare intraocular pressure (IOP) in pediatric patients undergoing general anesthesia.
  • To evaluate the effect of face mask application versus laryngeal mask airway (LMA) insertion on IOP.
  • To assess IOP changes during sevoflurane-induced general anesthesia in children.

Main Methods:

  • A before-and-after study involving 35 pediatric patients.
  • Measurement of IOP, blood pressure, oxygen saturation, and heart rate.
  • Comparison of IOP with a face mask, no face mask, and after LMA insertion under sevoflurane anesthesia.

Main Results:

  • A statistically significant difference in IOP was observed between face mask application and LMA insertion (p < 0.05).
  • However, this difference was not clinically significant.
  • No significant clinical changes in IOP were noted across the different airway management techniques.

Conclusions:

  • Clinically, intraocular pressure (IOP) remains stable in children during general anesthesia with sevoflurane.
  • The use of a correctly sized face mask does not significantly alter IOP compared to LMA insertion or no face mask.
  • Anesthesia providers can be reassured regarding IOP stability with standard airway management in pediatric patients.

Stages of General Anesthesia

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...

Increased Intracranial Pressure l: Introduction

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
General Anesthesia: Overview01:24

General Anesthesia: Overview

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...
Inhalational Anesthetics: Overview01:20

Inhalational Anesthetics: Overview

Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...
Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...
