Endotracheal administration for intraoperative acute massive pulmonary embolism during laparoscopic hepatectomy: A case report.

Introduction: Acute pulmonary embolism (APE) during an operation is a very urgent occurrence, especially when the patient with hemodynamic instability. Generally, drugs are administered intravenously; however, these drugs have little effects under most circumstances. We present a case of successful resuscitation in a patient with endotracheal administration. Patient concerns: A 67-year-old female presented for laparoscopic hepatectomy. Acute pulmonary gas embolism occurred during the operation with hemodynamic instability. The total amount of carbon dioxide and argon reached 300 mL. We used a novel way of administering drugs instead of intravenous administration for rescuing and the patient condition had improved greatly and was discharged from the hospital without any neurological deficits. Diagnoses: A diagnosis of APE was made because of a lot of gas was extracted out from central venous catheter and sudden observable decrease in end-tidal CO2. Interventions: These measures included endotracheal administration, position adjustment, manual ventilation, and gas extraction. Outcomes: The patient was discharged from the hospital and had no signs of neurological deficits. Conclusion: Intravenous administration may not the best appropriate way of administration when patients occurred APE. Endotracheal administration as a unique method may work wonders and has the value of research and application.
