Anévrisme IV : gestion infirmière
Une surveillance attentive de la rupture d’anévrisme est essentielle chez les patients subissant une chirurgie aortique.
Prise en charge infirmière pr…
Les soins infirmiers préopératoires pour les patients subissant une chirurgie endovasculaire comprennent l’évaluation régulière du pouls périphérique du patient et la surveillance des manifestations de rupture d’anévrisme, telles que la tachycardie, l’hypotension, la douleur dans les régions abdominale, l’aine, le dos ou le périumbilical et une masse abdominale pulsée.
Demandez au patient de consommer un régime liquide clair la veille de la chirurgie et de rester NPO après minuit avant la chirurgie.
Administrez des laxatifs oraux ou des lavements tels que prescrits et effectuez un nettoyage de la peau avec un agent antimicrobien la veille de l’opération.
Fournir des médicaments prescrits, tels que des antibiotiques.
Pour la prise en charge postopératoire des soins infirmiers, positionnez le patient en décubitus dorsal pendant 6 heures pour réduire la pression sur le site de ponction artérielle.
Surveiller les signes vitaux et effectuer des évaluations Doppler des pouls périphériques toutes les 15 minutes pendant les premières heures.
Évaluez le site d’accès pour détecter les saignements, les hématomes et les zones cyanosiques de forme irrégulière.
De plus, administrez de l’oxygène, des liquides intraveineux, des composants sanguins et des médicaments selon les prescriptions.

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.
