Severe bronchospasm at the termination of the cardiopulmonary bypass period is an unusual but dangerous complication of open-heart surgery. We report a case of severe unilateral bronchospasm detected at the end of the bypass period on the basis of high airway pressures with remarkable difficulties to deflate the right lung and it was relieved with bronchodilator therapy by intrapulmonary percussive ventilation. Fiberoptic bronchoscopic examination revealed unobstructed, free tracheobnncheal airway and capnographic finding was obstructive pattern. As in the previously published cases, the exact cause of bronchospasm remains unknown in our patient as well, but the possible causes of the bronchospasm are described.

Although rare, intraoperative allergic reaction can lead to significant morbidity and mortality. Clinical diagnosis is difficult as there is a need to differentiate from other causes of perioperative adverse reactions, such as side effects of administered drugs, or patients' medical conditions which may present with bronchospasm or hypotension. Intraoperative allergic reaction may be triggered by various agents. Among those, opioid-induced allergic reaction is scarcely reported. We report a case of a patient who has previously had allergic reaction to meperidine and intraoperatively showed fentanyl induced anaphylaxis or anaphylactoid reaction with literature reviews.

BACKGROUND: Propofol inhibits postoperative bronchospasm. Ketamine prevents bronchospasm in asthmatic patients. The present study was designed to evaluate the effects and mechanisms of propofol and ketamine on tracheal smooth muscles. METHODS: After isolating guinea-pig tracheal preparations, the maximal tracheal tones were induced by smooth muscle constrictors(2 10 7 M carbachol, 10 5 M histamine, 30 mM K+ Krebs solution, 124 mM K+ Krebs solution). When tracheal tones stabilized, propofol or ketamine was added cumulatively to obtain the concentration-relaxation curves, and calculated the ED50 and ED95. RESULTS: Propofol and ketamine decreased maximal tracheal tones in the concentration-dependent manners. The ED50 and ED95 of propofol were lowest in the histamine group, highest in the 30 mM K+ Krebs solution group. The ED50 and ED95 of ketamine were lowest in the 124 mM K+ Krebs solution group, highest in the histamine group. CONCLUSIONS: The relaxant effects of propofol and ketamine involve with all receptors in nonspecific way. However, propofol may inhibit more strongly the histamine mediated mechanism of tracheal contraction and ketamine may involve more strongly with Ca++ channel.

Fatal anaphylactic reactions to protamine sulfate during cardiac surgery are very rare. We report a case of catastrophic bronchial spasm due to an anaphylactic reaction to protamine. The patient was managed successfully using a bronchodilator, steroid treatment, and extracorporeal membrane oxygenation.

Severe bronchospasm after injection of succinylcholine iodide intravenously occurred in a 28 year old female during emergency Cesarean section. This was confirmed by repeated administration of the succinylcholine iodide and its symptoms with several referances are reviewed.
