ANESTHESIA IN THE BEACH CHAIR POSITION 615 discussion The beach chair position 30-90 above the horizontal plane is widely used for orthopedic shoulder arthroscopy procedures as it offers advantages such as excellent intraarticular visualization and reduced brachial plexus strain.

25 beach chair position anaesthesia. 1 In 2005 Pohl and Cullen published a 4-patient case series describing catastrophic cerebral ischemia in patients undergoing shoulder surgery in the BCP. Neer Award 2012. However a recent systematic review comparing beach-chair and lateral decubitus positioning in posteriorinferior instability of the shoulder stated across included studies and regardless of patient position there were no reported incidences of neuropraxia stroke nonfatal pulmonary embolus vision loss cardiac arrest or other.

Agents with greater preservation of cerebral blood flow CBF to cerebral metabolic rate for oxygen CMR o2 ratio. It is helpful to place the trunk almost upright with an almost hanging arm to help reduce the fracture by ligamentotaxis and gravity. Hypotension can occur due to venous pooling in the lower limbs and the vasodilatory effects of general anaesthesia.

Et al4 compared the beach-chair position to the lateral decubitus position in patients undergoing shoulder surgery undergeneral anesthesia and found significant reduc-tions in cerebral oxygenation in patients in the beach-chair position as opposed to the lateral decubitus position. Anesthetic agents have distinct effects on cerebral hemodynamics and metabolism 14 15 which may have implications for beach chair positioning. Desaturation and the risk of neurologic injury associated with anesthesia and surgery in the beach chair position for shoulder surgery.

There were no neurological deficits but patients with CDEs showed a greater negative impact. POSITIONING OF THE UPPER EXTREMITY Iin supine position shoulder abduction should be limited to 90. 1 2 This position affords better intra-articular visualization and less risk of neurovascular trauma than when patients are placed in the lateral decubitus.

Reduce the pressure at the ulnar nerve canal When the arms are placed to the sides forearm should be placed on neutral position Whenever the arms in abduction and supported on boards the forearm shd be in supine or neutral position External pressure on radial n at humeral groove shall be avoided Positioning of the lowerextremity The lithotomy position. The incidence of cerebral desaturation events CDEs was 25. Hence while doing shoulder surgery in an upright position if a blood pressure reading for a cuff placed at the level of the heart is 12080 mmHg and there is 25 cm of elevation between it and the external auditory meatus the cerebral pressure is 10262.

During procedures in the BCP or sitting position the head should be secured in a neutral position to avoid flexion or extension. Approximately two-thirds of the 400000 shoulder surgery procedures performed annually in the United States are performed with the patients head elevated above the horizontal a position know as the beach chair position BCP. To be aware of potential cerebral monitoring options.

The blood pressure drop 5 min after beach chair position measured at the acoustic meatus level in the CDE group was higher compared to patients without CDEs p 0009 as was the rScO 2 p 0039 and the Vmax MCA p 0002. At our insti-tution we performed a small study with. The mechanism of neurologic injury in the beach chair position.

Most surgeons will request 2025 degrees of head elevation. To be aware of the latest research concerning patients at. Patient positioning and related concerns The beach chair position.

Bring the torso up into the beach chair position. The beach chair position allows better surgical visualization compared to lateral decubitus position but may be associated with catastrophic neurologic complications including stroke spinal cord ischemia and transient visual loss. 2 This series has prompted investigators to study how intraoperative management factors.

This is often used in shoulder procedures to facilitate surgical access and minimize bleeding. A prospective study on the effect of general anesthesia compared with regional anesthesia and sedation. Secure the head to an appropriate head rest and secure the oral tube.

The upper extremity must be freely movable. Although Tange et al7 reported that the use of the beach chair position under general. As a general rule a.

Lawn Chair Position modification of the standard supine position the lower and upper halves of the body are slightly elevated in relationship to the hips Better venous drainage better muscle relaxation 16. Hypoperfusion for patients anesthetized in the beach chair position. In the United States approximately two-thirds of these patients undergo anesthesia and surgery in the sitting or beach chair position BCP1 Although the BCP offers several advantages for the surgeon including reduced risk of neurovascular trauma ease of conversion to an open approach and excellent intra-articular visualization2 the sitting position introduces several challenges for the.

Although shoulder surgery can be conducted in the lateral decubitus position the majority of surgeons in the United States use the sitting or beach chair position BCP. To understand the various influences on cerebral oxygenation for patients anesthetized in the beach chair position. Beach chair position 17.
