The patient is moved into the upright beach chair position in conjunction with the anesthesia staff to ensure that the patient does not become hypotensive during this positioning maneuver. We recommend cycling the blood pressure before raising the head to have accurate and current blood pressure data. Attention is then turned to the contralateral arm, which is placed in a padded arm holder LPS Arm Support, Arthrex to ensure that the wrist is in a neutral position and avoids compression of the ulnar nerve.
The positioner should allow for adequate external rotation of the operative shoulder. Once the patient is properly positioned , a final preparation timeout is performed to confirm the operative side for patient safety. Next, sterile preparation and draping can proceed. The operative extremity is prescrubbed with chlorhexidine solution. The forearm of the operative extremity is held while the surgeon cleans the skin with sterile 3M ChloraPrep CareFusion, San Diego, CA from the axilla to the hand and nipple to the medial border of the scapula.
The surgeon uses a sterile stockinette 3M Health Care, St. Paul, MN to cover the hand. A sterile plastic blue U-Drape U-drape, 3M Health Care is placed across the neck and down the chest and back to isolate the sterile field, followed by a second plastic blue U-Drape U-drape, 3M Health Care across the axilla and up the chest and back. A sterile drape with an arthroscopic fluid collection pocket and associated drain is then used 3M Health Care.
This drape will isolate anesthesia from the sterile field.https://deiprudearabas.ml/qenox-espiar-conversaciones-en.php

The surgeon will then use a pen on the skin for landmarks of the acromion, clavicle, and coracoid to determine the positions of the portals. Once these landmarks have been identified, one sheet of Ioband 3M Health Care is cut into quarters, and fixed to the edges of the operative area to prevent the drapes from pulling away from their position.
At the conclusion of patient positioning, the surgical team should change gloves and conduct a final preincision timeout. Arthroscopic shoulder surgery is highly effective at treating shoulder pathology and continues to grow in popularity because of its success.
Arthroscopy offers several advantages versus open procedures including decreased morbidity, length of hospital stay, and postoperative pain, in addition to improved cosmesis. The 2 positions that may be used when performing shoulder arthroscopy are the beach chair and lateral decubitus positions. The position chosen is chiefly dependent on surgeon preference and neither has been shown to be superior to the other. Cerebral hypoperfusion is a recognized and catastrophic complication of the beach chair position. However, Pohl and Cullen 15 reported that hyperextension and rotation or tilt of the head can decrease vertebral artery flow, resulting in infarcts in the distribution of the posterior cerebral artery.
Furthermore, Park and Kim 22 reported a case series of neuropraxia thought to have been caused by malposition of the head and neck in the beach chair position resulting in excess pressure on superficial nerves. Thus, the surgeon must be vigilant in assuring proper head alignment during patient positioning as well as proper padding of bony prominences. Finally, during sterile preparation of the surgical field, care should be taken to isolate the surgical field while maintaining satisfactory area to place the relevant portals.
The advantages of the beach chair position have been outlined in the literature as having a lower incidence of neuropathies, decreased risk of neurovascular complications during portal placement, decreased surgical time, easier conversion to an open procedure, and better visualization of the joint.
