Insights

Paediatric eye exams in an outpatient sedation unit are more cost-effective than those under general anaesthesia. While slightly fewer procedures were completed, significant savings were observed, making it a valuable alternative for children

Area of Science:

  • Ophthalmology
  • Health Economics
  • Pediatrics

Background:

  • Detailed pediatric eye examinations often require general anesthesia (GA) due to patient intolerance.
  • Assessing cost-effectiveness is crucial for optimizing healthcare resource allocation in pediatric eye care.

Purpose of the Study:

  • To evaluate the incremental cost-effectiveness of pediatric eye examinations performed in an outpatient sedation unit versus general anesthesia.
  • To compare the costs, adverse events, and success rates of two distinct examination settings.

Main Methods:

  • A societal perspective cost-effectiveness analysis was performed.
  • A retrospective cross-over cohort design included Canadian children under 7 years old.
  • Decision analysis modeled costs, adverse events, and successful procedures with sensitivity analyses.

Main Results:

  • Examinations under sedation (EUS) cost $406 per patient, while examinations under anesthesia (EUA) cost $1135.
  • EUS yielded 1.39 successful procedures per patient, compared to 2.06 for EUA.
  • EUA was $729 more expensive but resulted in 0.68 more successful procedures per child.

Conclusions:

  • Cross-over designs are effective for comparing intervention costs and effectiveness.
  • Pediatric ophthalmological exams in hospital outpatient clinics offer significant cost savings.
  • Outpatient sedation provides a cost-effective alternative to general anesthesia for pediatric eye examinations, despite a potential slight decrease in completed procedures.

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...

Parenteral Anesthetics: Overview01:24

Parenteral Anesthetics: Overview

Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.

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...

Local Anesthetics: Clinical Application as Epidural Anesthesia

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

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...
