Summary
Operating room delays increase throughout the day. This study examined nonoperating room anesthesia (NORA) tardiness, finding it worsened as the day progressed, except in diagnostic radiology, due to limited workflow improvements.
Area of Science:
- Anesthesiology
- Healthcare Management
- Medical Operations
Background:
- Operating room (OR) tardiness impacts surgical workflow and patient care.
- Previous studies indicate OR delays decrease as the day progresses.
- Nonoperating room anesthesia (NORA) services present unique scheduling challenges.
Purpose of the Study:
- To analyze tardiness trends in NORA services at the University of Vermont Medical Center.
- To identify patterns of delay across different NORA service lines throughout the surgical day.
- To understand factors contributing to NORA tardiness.
Main Methods:
- Retrospective analysis of NORA cases performed in the 2015 calendar year.
- Tardiness calculated by subtracting scheduled start times from actual start times.
- Data segmented by NORA service line and time of day.
Main Results:
- Overall NORA tardiness increased as the surgical day progressed.
- Diagnostic radiology was an exception, showing no significant increase in tardiness.
- Limited opportunities for tactical and operational workflow adjustments likely contributed to the observed trend.
Conclusions:
- NORA tardiness escalates throughout the day, unlike traditional OR cases.
- Diagnostic radiology NORA services may benefit from distinct operational strategies.
- Further investigation into workflow optimization for NORA services is warranted to mitigate delays.

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...

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...

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
1.5K
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

01:29Local Anesthetics: Clinical Application as Epidural Anesthesia
762
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...

01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
1.4K
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.

2.1K
Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...
