Immediate Anaesthetic Management for Fat Embolism During Surgery

Airway and Oxygenation Strategy

The American Society of Anesthesiologists recommends performing endotracheal intubation with the patient in head-up position (20-30 degrees) to optimize respiratory mechanics and reduce atelectasis 1
The Anaesthesia society suggests using pressure-controlled ventilation rather than volume-controlled ventilation, as this achieves greater tidal volumes for a given peak pressure 1
The American Thoracic Society recommends maintaining PEEP of 7-10 cm H2O continuously throughout the procedure to prevent airway closure and keep the lung open 1
Position patient in slight sitting/head-up position throughout surgery to allow increased abdominal excursion and lower airway pressures, as recommended by the Anaesthesia society 1

The American College of Surgeons recommends establishing two large-bore intravenous cannulae immediately, using ultrasound guidance if needed, and consider unusual sites (upper arm, anterior chest wall) given potential difficulty 1, 2

The Anaesthesia society recommends using short-acting agents exclusively (desflurane or sevoflurane over isoflurane, or propofol TCI) to allow rapid emergence and assessment of neurological status, as fat emboli can cause cerebral dysfunction 1, 3
Desflurane provides faster return of airway reflexes compared to sevoflurane and should be preferred, according to the Anaesthesia society 1, 2
The American Society of Anesthesiologists recommends implementing depth of anesthesia monitoring to limit anesthetic load and reduce risk of awareness 1, 4
The Anaesthesia society suggests using neuromuscular monitoring continuously to maintain appropriate block level and ensure complete reversal before emergence 1, 2
Reverse neuromuscular blockade completely using quantitative monitoring before attempting extubation, as respiratory mechanics are already severely compromised, as recommended by the Anaesthesia society 3, 2

The American Society of Anesthesiologists recommends implementing multimodal opioid-sparing analgesia (local anesthetics, regional techniques) to minimize respiratory depression in the setting of already compromised gas exchange 1, 3, 2
The American Pain Society recommends avoiding long-acting opioids given the risk of postoperative respiratory depression 4

The Anaesthesia society recommends only extubating when patient is fully awake with complete return of airway reflexes, breathing with good tidal volumes, and hemodynamically stable 3, 2
Perform extubation with patient in sitting position to maintain optimal respiratory mechanics, as recommended by the Anaesthesia society 3, 2
The American Thoracic Society recommends having nasopharyngeal airway available before emergence to mitigate partial airway obstruction 3, 2

The American Thoracic Society recommends continuing supplemental oxygen and monitoring oxygen saturations continuously, as fat embolism causes prolonged hypoxemia 3
The American Society of Anesthesiologists recommends observing for signs of hypoventilation, apnea, or hypopnea with associated desaturation requiring extended PACU monitoring 3, 2
