Bronchospasm induced by propofol in a patient with sick house syndrome

IMPLICATIONS: Propofol is often used in patients with asthma, but it can induce bronchospasm. We report a patient with sick house syndrome (nonspecific complaints of mucosal irritation, headache, nausea, and chest symptoms) who suffered bronchospasm. This case suggests that propofol is not always a safe anesthetic for patients with asthma, especially drug-induced asthma.     

Sudden hypoxia during anesthesia in a patient with Kartagener's syndrome

We report a case of anesthesia in an adolescent with recurrent left pneumothorax, Kartagener's syndrome, and severe learning disability with behavioral difficulties. After induction of anesthesia, he rapidly developed severe desaturation as measured on pulse oximetry. Placement of an intercostal chest drain did not remedy the situation and he was found to have blocked the left main bronchus with viscous secretions. Subsequent suctioning relieved the obstruction. Despite successful postoperative thoracic epidural analgesia and minitracheostomy for bronchial toilet, he developed bronchopneumonia that resolved with antibiotics. We discuss anesthesia for patients with Kartagener's syndrome and for patients with pneumothorax.     

ECG changes during emergence from anesthesia in a patient with LEOPARD syndrome

LEOPARD syndrome is a rare congenital disease characterized by seven features. Besides the original clinical manifestations, hypertrophic cardiomyopathy was reported as an additional laboratory finding recently. We gave general anesthesia to a child of this syndrome, and encountered ECG changes during emergence from anesthesia. The diagnosis was made in her infancy, and had been receiving beta-blocker treatment ever since. The preoperative examination showed remarkable right axis deviation in ECG, and asymmetric ventricular septal hypertrophy in echocardiography. After the operation, several kinds of arrhythmia (i.e. atrioventricular junctional rhythm, atrioventricular dissociation, etc), were observed and they continued for a few minutes. Careful planning for the perioperative management of this syndrome is mandatory. The cardiomyopathy must be examined beforehand. We made an effort to prevent the extreme changes of pre- and after-load during the general anesthesia.     

Ventricular tachycardia during general anesthesia in a patient with congenital long QT syndrome

PURPOSE: Congenital long QT syndrome is characterized by a corrected QT interval of at least 440 msec on the electrocardiogram and has been associated with recurrent syncope, documented ventricular arrhythmia and sudden death. There have been numerous articles over the past 20 years describing isolated instances of surgical and anesthesia related complications but the general anesthetic management of the condition remains unclear. CLINICAL FEATURES: An 11-yr-old female with documented long QT syndrome, with two episodes of syncope in the past, was admitted for emergency drainage of left periorbital cellulitis. Anesthesia was induced with propofol, fentanyl and rocuronium, and initially maintained with nitrous oxide and halothane. After 20 min, the patient developed ventricular tachycardia (torsade de pointes). Lidocaine 1 mg.kg(-1) iv was given and the rhythm reverted to normal sinus. Halothane was discontinued and the surgery proceeded without further incident. CONCLUSIONS: Our review of the literature revealed that patients with long QT syndrome whose symptoms are well controlled prior to surgery tend to do well regardless of the anesthetic chosen. There are, however, theoretical reasons to avoid anesthetics which either sensitize the myocardium to catecholamines or which cause an increase in circulating levels of catecholamines.     

Discrepancy between electroencephalography and hemodynamics in a patient with Cockayne syndrome during general anesthesia

Cockayne syndrome is a kind of progeria with autosomal chromosome recessiveness described first by Cockayne in 1936. Patients with this syndrome were characterized by retarded growth, cerebral atrophy, and mental retardation. We experienced an anesthetic management of a patient with Cockayne syndrome, who underwent dental treatment twice. The primary concern was discrepancy between electroencephalography and hemodynamics. The values of bispectral index showed a sharp fall to 1 digit and suppression ratio more than 40, while hemodynamics was stable during induction of anesthesia with sevoflurane 8%. We should pay attention to anesthetic depth in the central nervous system in patients with Cockayne syndrome. Titration of anesthetics should be performed by the information from electroencephalography.     

Profound bradycardia with lidocaine during anesthesia induction in a silent sick sinus syndrome patient

Sick sinus syndrome is caused by sinus node dysfunction that renders it unable to function as a pacemaker. Patients with sick sinus syndrome are often asymptomatic or have symptoms that are mild and nonspecific. Lidocaine (0.5 mg/kg) injection is used for reduction of pain associated with intravenous injection of propofol. Episodes of marked bradycardia with sinus arrest after prophylactic lidocaine injection are reported in a 69-y-old man with no apparent preoperative cardiac disease or electrocardiographic abnormality. Surgery was postponed, and he was later diagnosed with sick sinus syndrome.     

Regional anesthesia for a patient with stiff-person syndrome

We report a case of stiff-person syndrome (SPS). A 65-year-old male underwent an emergency pacemaker implantation for syncope. With lidocaine infiltration under fentanyl and propofol sedation, the operation was completed without complications. Muscle rigidity and spasms are exacerbated by sensory and emotional stimuli in SPS. However, the present case suggests that regional anesthesia is also acceptable under adequate sedation.     

Considerations for general anesthesia combined with epidural anesthesia in a patient with stiff-person syndrome

We report the successful management of anesthesia in a patient with stiff-person syndrome (SPS) undergoing a thymectomy using a volatile anesthetic combined with epidural anesthesia. The anesthetic concern in patients with SPS is the possibility of postoperative hypotonia due to the presence of excessive γ-aminobutyric acid (GABA) resulting from an interaction between the anesthetic agents and preoperatively taken therapeutic drugs. Epidural anesthesia has the advantages of decreasing the required amount of anesthetics with GABAergic action, and relieving the postoperative pain that causes the symptoms of SPS. Epidural anesthesia could be a useful technique in SPS patients.     

Bronchospasm during crush induction with propofol under the Sellick maneuver in a patient for emergency laparotomy

A 61-year-old man was scheduled for an emergency laparotomy due to ileus. He had a history of asthma, but it was well controlled without medication. Anesthesia was induced with propofol and ketamine under the Sellick maneuver. Following administration of vecuronium, endotracheal intubation was performed. However, he could not be ventilated. We thought that the tube had been inserted into the esophagus, and re-intubation was performed. However he could not be ventilated as in the first trial. At that time, we suspected that bronchospasm had occurred. Bronchospasm improved rapidly using hyperventilation with 100% oxygen and 3-5% sevoflurane, and intravenous aminophylline. Because he had a history of asthma, propofol was relatively indicated from the point of smooth muscle relaxant effects. However we should consider the risk of bronchospasm in a patient with a history of asthma, even if we use propofol.
