[Postoperative delirium after regional anesthesia].
1Division of Anesthesiology, Orthopedic Surgery Department, Zagreb University Hospital Center, Zagreb, Croatia.
Summary
Postoperative delirium is common after major surgery. While regional anesthesia may reduce its incidence, more research is needed to confirm its impact on preventing acute confusional states.
Area of Science:
- Anesthesiology
- Geriatrics
- Neuroscience
Context:
- Postoperative delirium (POD) is a frequent complication following major surgery, impacting patient recovery and outcomes.
- Identifying modifiable risk factors, such as anesthetic technique, is crucial for POD prevention strategies.
Purpose:
- To review current knowledge on risk factors for postoperative delirium.
- To evaluate the role and importance of anesthetic technique in the incidence of POD.
Summary:
- Patient factors (age, cognitive status, comorbidities) and perioperative events (hypotension, hypoxemia, pain) contribute to POD risk.
- While regional anesthesia may offer benefits over general anesthesia in reducing POD, evidence remains inconsistent.
- Further large-scale, randomized trials are necessary to establish definitive conclusions on anesthetic technique's influence on POD incidence.
Impact:
- Understanding POD risk factors aids in developing targeted prevention and management protocols.
- This review highlights the need for high-quality research to optimize anesthetic choices for minimizing postoperative delirium.
- Improved POD management can lead to better patient outcomes and reduced healthcare costs.

01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
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.

01:24General 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...

01:22Stages 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...
01:12Local Anesthetics: Adverse Effects
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

01:24Parenteral 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.
01:29Local 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...
