Comparative Study Clinical Trial
[Intravenous patient controlled analgesia combined with continuous thoracic epidural analgesia for post-thoracotomy pain].
We compared the efficacy of intravenous patient controlled analgesia of buprenorphine plus continuous thoracic epidural infusion of bupivacaine (IV-PCA group) with the efficacy of continuous thoracic epidural infusion of bupivacaine and buprenorphine (the TEA group). No patient in IV-PCA group required supplemental analgesics, while 90% of TEA group required supplemental intramuscular buprenorphine to relieve post-thoracotomy pain. In TEA group, 94% of the supplemental drugs were administered during night shifts. These results indicate that IV-PCA of buprenorphine combined with continuous thoracic epidural infusion of bupivacaine is more effective analgesic management than continuous TEA with buprenorphine and bupivacaine.

We report a case of unexpected difficult intubation in an adult caused by a laryngeal web. A 43-year-old woman with uterine myoma was scheduled for abdominal hysterectomy. After induction of anesthesia, the vocal cords were seen clearly under laryngoscopy. ⋯ Bronchoscopy revealed a very narrow airway below the level of vocal cords caused by a laryngeal web. Tracheostomy was performed. Two weeks later, tracheostomy was closed without any sequela.

A 76-year-old woman with thoracic aortic aneurysm involving distal aortic arch was scheduled for graft replacement from ascending to proximal aortic arch with endovascular stent graft to descending aorta. Surgical procedures were performed under median sternotomy with hypothermic systemic circulation arrest and selective cerebral perfusion. The stent graft composed of 30 mm Gianturco Z stent and 27.5 mm woven Dacron graft was introduced into the descending aorta under the guidance of transesophageal echocardiography (TEE) and fluoroscopy. ⋯ TEE was also useful to find the dislodgement of the stent graft after deployment. This surgical technique, being less invasive than conventional thoracotomy, would be indicated for elderly patients with distal aortic arch aneurysm. TEE is the vital imaging technique for placement of the stent graft, as well as for intraoperative cardiac monitoring.

We conducted an anesthetic management to perform tracheostomy and tracheolysis in a 33 year-old female with severe stenosis extending to the lower trachea and right main bronchus. The minimal diameter of the stenotic lesion of the trachea was 3 mm according to the preoperative examinations including tomography, CT scan and magnetic resonance imaging. ⋯ Total intravenous anesthesia with propofol and fentanyl could provide adequate depth of anesthesia during surgery and rapid recovery with good spontaneous respiration after the termination of the infusion. VV-ECMO was a useful method to support gas-exchange in a case not requiring circulatory assistance without uneven oxygenation sometimes observed in VA-ECMO.

We reported 131 cases of ambulatory surgery in adults mainly anaesthetized with propofol infusion. Without any premedication, anesthesia was induced with propofol and fentanyl. A laryngeal mask airway was inserted using intravenous injection of vecuronium. ⋯ In 25 patients (19%) analgesics were needed for postoperative pain. Although 3 patients (2.3%) were unsuccessful as ambulatory surgery due to excessive pain, all patients including these three could be discharged within 24 hours after surgery. We conclude that combined anesthesia with propofol, fentanyl and local anesthetic is suitable for ambulatory surgery in adults.
