Ultrasound-guided fascia iliaca compartment block combined with general anesthesia for amputation in an acute myocardial infarction patient after percutaneous coronary intervention: A case report

BACKGROUND: Fascia iliaca compartment block is a technique that blocks three nerves, similar to a 3-in-1 nerve block. This block provides analgesia for patients undergoing lower limb surgery, and is a simple technique that is easy to implement. Here, we report a case of fascia iliaca compartment block in a patient with myocardial infarction who underwent emergency middle thigh amputation. CASE SUMMARY: A 78-year-old female patient weighing 38 kg with gangrene and occlusive peripheral atherosclerosis of the right leg underwent an emergency middle thigh amputation. The patient had a history of hypertension, coronary heart disease, cerebral infarction, anterior wall myocardial infarction, and had recently undergone percutaneous coronary intervention consisting of coronary angiography and right coronary artery stent implantation. Considering the patient's condition, an ultrasound-guided fascia iliaca compartment block combined with general anesthesia was implemented for amputation. The fascia iliaca compartment block provided analgesia for the operation, and reduced the dosage of general anesthetics. It also alleviated adverse cardiovascular effects caused by pain stress, and ensured the safety of the patient during the perioperative period. This block also provided postoperative analgesia. The patient had a good prognosis, and was subsequently discharged from hospital. CONCLUSION: Fascia iliaca compartment block provides surgical analgesia. It also alleviates adverse cardiovascular effects, and ensures patient safety during the perioperative period.
