動脈瘤 IV: 看護管理
動脈瘤破裂の監視は、大動脈手術を受けている患者にとって重要です。
手術前の看護管理
動脈瘤破裂の兆候（顔面蒼白、脱力感、頻脈、低血圧、腹部、背中、鼠径部、または臍周辺の痛み、意識の変化、拍動性腹部腫瘤）について患者を継続的に監視します。患者の末梢脈拍を定期的に評価します。

血管内手術を受ける患者さんの術前看護ケアには、患者さんの末梢脈拍の定期的な評価や、頻脈、低血圧、腹部、鼠径部、背中部、臍周囲部の痛み、腹部の脈動などの動脈瘤破裂の兆候のモニタリングが含まれます。
手術前日に透明な流動食を摂取し、手術前の深夜以降もNPOに留まるように患者に指示します。
処方されたとおりに経口下剤または浣腸を投与し、手術の前日に抗菌剤による皮膚洗浄を行います。
抗生物質などの処方薬を提供します。
術後の看護管理のために、動脈穿刺部位への圧力を減らすために、患者を6時間仰臥位にします。
バイタルサインを監視し、最初の数時間は15分ごとに末梢パルスのドップラー評価を実行します。
出血、血腫、および不規則な形状のチアノーゼ領域のアクセス部位を評価します。
さらに、酸素、IV液、血液成分、および薬を注文どおりに投与します。

Q1: What are the key signs of aneurysm rupture that nurses should monitor before surgery?
Nurses must continuously monitor for clinical manifestations and diagnostic indicators of rupture, including tachycardia, hypotension, pallor, weakness, abdominal or back pain, changes in consciousness, and a pulsating abdominal mass. Regular assessment of peripheral pulses is essential. Immediate reporting of these signs enables rapid intervention and prevents life-threatening complications.
Q2: How should patients be prepared the day before endovascular aneurysm surgery?
Preoperative preparation includes instructing patients to consume a clear liquid diet and remain NPO after midnight. Administer prescribed oral laxatives or enemas and perform skin cleansing with antimicrobial agents. Provide prescribed medications, including intravenous antibiotics. These measures reduce infection risk, prevent aspiration, and ensure optimal surgical conditions.
Q3: Why is patient positioning critical during the immediate postoperative period after aneurysm repair?
Positioning the patient supine for 6 hours reduces pressure on the arterial puncture site, typically the femoral artery, preventing bleeding and hematoma formation. After 2 hours, the head of the bed may be elevated up to 45 degrees. This positioning strategy protects the access site while maintaining hemodynamic stability during early recovery.
Q4: What postoperative assessments should nurses perform on peripheral pulses and access sites?
Nurses perform Doppler assessments of peripheral pulses every 15 minutes initially, assessing femoral, posterior tibial, popliteal, and dorsalis pedis pulses for descending aorta surgeries. Continuously monitor the access site for bleeding, hematoma, and irregularly shaped cyanotic areas indicating embolization. Report any changes in pulse quality, vital signs, swelling, pain, or pulsation immediately.
Q5: How do nurses monitor for postimplantation syndrome after aneurysm repair?
Postimplantation syndrome presents with spontaneous fever, leukocytosis, and transient thrombocytopenia. Nurses monitor laboratory results for elevated white blood cell counts and assess vital signs regularly. Understanding these expected inflammatory responses helps distinguish normal postoperative reactions from infection, guiding appropriate clinical decision-making and patient management.
Q6: What fluid and medication management strategies support postoperative aneurysm repair recovery?
Administer IV fluids, electrolytes, and blood components as ordered to maintain adequate blood flow. Monitor central venous pressure and urine output hourly to assess hydration and perfusion status. Provide prescribed diuretics, antihypertensive agents, analgesics, and antidysrhythmics. Maintain continuous ECG monitoring and oxygen therapy to enhance myocardial oxygen supply and prevent complications.
Q7: How should nurses manage nasogastric tubes and promote bowel function after aneurysm surgery?
Connect the NG tube to low, intermittent suction to decompress the stomach, prevent aspiration, and reduce pressure on suture lines. Record the amount and character of NG output. Assess bowel sounds every 4 hours and encourage early ambulation to restore bowel function. Six hours postoperatively, patients may roll side to side and ambulate with assistance.
