Morton White,a 68-Year-Old,ASA PS-2 Male with Early-Stage Prostatic Cancer,was Intubated

Morton White,a 68-year-old,ASA PS-2 male with early-stage prostatic cancer,was intubated and positioned for a robotic-assisted laparoscopic radical prostatectomy.The initial position for insertion of the trocars was supine with arms tucked and secured within under-mattress sled arm positioners padded with gel.His hands were placed in a natural position with the fingers wrapped around gauze rolls and touching his lateral thighs.The new anesthesia provider,who had never seen a robotic prostatectomy,was concerned about anesthesia implications when the patient would be repositioned into extreme Trendelenburg for the dissection and anastomosis.The circulating nurse assured her that they would implement protective measures and work together to ensure the best patient outcome.Select all of the potentially harmful effects of extreme 45-degree Trendelenburg in a robotic procedure.

A) Respiratory compromise and ventilation resistance,patient sliding,facial edema
B) Pelvic pressure from abdominal organs,finger injury from hands pressed against thighs,popliteal pressure within stirrups
C) Accidental deployment of unlocked OR bed remote control while instruments are inside patient,causing external and internal tissue injury
D) Heel pressure injury from stirrup boot,hyperabduction injury to the arms,pulmonary embolism
