Anaesthesia for neurosurgery in the sitting position
1Department of Anaesthesia and Pain Management, Royal Melbourne Hospital, Parkville, Vic. 3050, Australia.
Summary
The sitting position aids posterior fossa and spine surgery but carries risks like air embolism and hypotension. Neuroanesthetists must manage these potential complications for patient safety.
Area of Science:
- Neurosurgery
- Anesthesiology
Background:
- The sitting position improves surgical access for posterior fossa and cervical spine procedures.
- This position presents significant anesthetic risks, including air embolism and hemodynamic instability.
Purpose of the Study:
- To review the advantages and disadvantages of the sitting position in neurosurgery.
- To outline the management of complications associated with the sitting position from a neuroanesthetist's viewpoint.
Main Methods:
- Literature review focusing on neuroanesthesia and surgical positioning.
- Analysis of risks and benefits of the sitting position in posterior fossa and spine surgery.
Main Results:
- Key advantages include enhanced surgical visualization and access.
- Major risks involve venous/arterial air embolism, hypotension-induced ischemia, and positioning complications.
Conclusions:
- Careful patient selection and vigilant neuroanesthetic management are crucial.
- Balancing surgical benefits with anesthetic risks is essential for safe application of the sitting position.

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
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
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...

01:24General 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...
01:24Parenteral 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.

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
