Awake nasotracheal intubation under bronchoscopic guidance and anesthetic management in a patient undergoing excision of an endotracheal mass

Abstract Noonan syndrome (NS) is an autosomal dominant disorder characterized by facial anomalies, short stature, chest deformity, congenital heart diseases, and other comorbidities. The challenges faced during anesthetic management of patients with NS could be due to congenital heart diseases, hemostatic disorders, and airway anomalies. Here we describe dental treatment under general anesthesia performed for a 28-year-old man with NS. He had characteristic features of NS along with mild pulmonary valve stenosis. Dental treatment under general anesthesia was performed successfully on 13 occasions with nasotracheal intubation under curve-tipped suction catheter guidance or insertion of a reinforced laryngeal mask airway. This case suggests that for patients with NS, who might present several challenges, dental anesthesiologists should consider the extent of the patient's disorders to enable them to perform dental treatment safely under general anesthesia.

Abstract Apert syndrome is a rare autosomal dominant disorder characterized by craniofacial abnormalities, craniosynostosis and syndactyly. Nasotracheal intubation for a patient with Apert syndrome can be a challenge because of abnormal facial anatomy. We experienced the anesthetic management of a patient with Apert syndrome who underwent partial resection of mandible and cleft palate repair with nasotracheal intubation. Nasotracheal intubation using a gastric tube and extubation using an airway exchange catheter proved useful in this case of airway compromise.

Probability Of Death

Background: Objective evaluation of the management of patients with ruptured infrarenal aortic aneurysm in emergency situations has been described rarely. Patients and methods: Fifty-two consecutive patients with ruptured infrarenal aortic aneurysm (mean age, 70.3 years; range, 56–89 years; SD 7.8) were admitted between January 1993 and March 1998. Emergency protocols, final reports, and follow-up data were analyzed retrospectively. APACHE II scores at admission and fifth postoperative day were assessed. Results: The time between the appearance of first symptoms and the referral of patients to the hospital was more than 5 hours in 37 patients (71%). Thirty-eight patients (71%) had signs of shock at time of admission. Ultrasound was performed in 81% of patients as the first diagnostic procedure. The most frequent site of aortic rupture was the left retroperitoneum (87%). Intraoperatively, acute left ventricular failure occurred in four patients, and cardiac arrest in two others. The postoperative course was complicated significantly in 34 patients. The overall mortality rate was 36.5% (n = 19). In 35 patients, APACHE II score was assessed, showing a probability of death of more than 40% in five patients and lower than 30% in 17 others. No patient showing probability of death of above 75% at the fifth postoperative day survived (n = 7). Conclusions: Ruptured aortic aneurysm demands surgical intervention. Clinical outcome is also influenced by preclinical and anesthetic management. The severity of disease as well as the patient’s prognosis can be approximated using APACHE II score. Treatment results of heterogenous patient groups can be compared.

Local anesthesia is a safe and less invasive anesthetic management for the endovascular approach to elective aortic aneurysm. We have successfully extended the indication of local anesthesia to a high-risk patient with leaking aneurysm and stable hemodynamics. Patient and methods: A 86 year old patient with renal insufficiency due to longstanding hypertension, coronary artery and chronic obstructive lung disease was transferred to our hospital with a leaking abdominal aortic aneurysm. Stable hemodynamics allowed to perform a fast CT scan, that confirmed the feasibility of endovascular repair. A bifurcated endograft (24mm x 12mm x 153mm) was implanted under local anesthesia. Results: The procedure was completed within 85 minutes without problems. The complete sealing of the aneurysm was confirmed by CT scan on the third postoperative day. Twenty months later, the patient is doing well and radiological control confirmed complete exclusion of the aneurysm. Discussion: The endoluminal treatment is a minimally invasive technique. It's feasibility can be rapidly assessed by CT scan. The transfemoral implantation can be performed under local anesthesia provided that hemodynamics are stable. This anesthetic management seems to be particularly advantageous for leaking abdominal aortic aneurysm since it doesn't change the hemodynamic situation in contrast to general anesthesia. Hemodynamic instability, abdominal distension or tenderness may indicate intraperitoneal rupture and conversion to open graft repair should be performed without delay.

Anesthesia for laboratory animals is a matter of biomedical concern and one of the most present dilemmas in the current bioethical debate. The use of anesthetic agents in experimental surgery aims at analgesia and restraining the animal, in order to achieve a reasonable degree of muscle relaxation and to produce sufficient analgesia. This practice requires the use of protocols for the administration of safe and efficient doses. Eight New Zealand rabbits were submitted to laparotomies demonstrating the surgical technique discipline of the local medical course. For pre-anesthetic medication, acepromazine 1 mg.kg-1 associated with ketamine 15 mg.kg-1 was used subcutaneously. Anesthesia was maintained with isoflurane and oxygen under a laryngeal mask in a Mapleson D anesthesia system and under spontaneous breathing. Hydration was performed with 10 ml.kg-1 saline every hour. A thermal mattress was used. Precordial stethoscope, pulse oximetry and clinical parameters were used for monitoring. For euthanasia, ketamine 10 mg.kg-1 associated with potassium chloride 19.1% 1 ml.kg-1 was used intravenously. The average weight of the rabbits was 2721.25 ± 275.01 grams and the duration of the anesthetic procedure was 120 ± 87 minutes. Discussion. In long-term anesthesia, such as laparotomies, the use of pre-anesthetic medication and then anesthetic induction by the combination of agents is recommended. However, anesthetic management requires monitoring to prevent insufficient or excessive doses from occurring.
