Accidental Epidural Injection of Ondansetron : A case report / 대한마취과학회지

We encountered a case of an accidental epidural injection of ondansetron through an epidural catheter. No neurological complications were noted. This case highlights the need for more attention to minimize the risk of epidural injections.

Open Lock of the Jaw on Induction of Anesthesia: A case report / 대한마취과학회지

The temporomandibular joint can be dislocated during anesthesia as a result of excessive oral opening and direct laryngoscope handling. Occasionally, yawning can be observed during the induction of anesthesia with propofol. The forceful and voluntary yawning after a propofol injection can lead to a dislocation of the temporomandibular joint. We report a case of an anterior dislocation of the temporomandibular joint upon induction with propofol, which caused difficulties in mask ventilation and endotracheal intubation. Although intubation had been carried out successfully in this case, an unanticipated difficult airway can be confronted at anytime. Therefore, anesthesiologists should be aware of the management of a difficult airway and practice various methods according to a difficult airway algorithm.

Use of Nicardipine and Esmolol in the Anesthetic Management for Bilateral Pheochromocytoma: A case report / 대한마취과학회지

Pheochromocytoma stems from the chromaffin cell and mostly is located in the adrenal medulla. It is an important cause of secondary hypertension due to correction of hypertension by a resection of the tumor. Because it produces and secretes catecholamine, it bothers anesthesiologists with excessive hypertension, tachycardia and arrhythmia during the anesthetic period. Therefore, anesthetic management is directed to avoid these conditions. We report a case of bilateral pheochromocytoma successfully managed intraoperatively with an infusion of nicardipine and an intermittent esmolol injection.

Comparison between High Flow and Low Flow Anesthesia for Positive Pressure Ventilation in Pediatrics Using the Laryngeal Mask Airway / 대한마취과학회지

BACKGROUND: Low flow anesthesia provides many advantages, including reduced cost, conservation of body heat and airway humidity. This study was performed to compare low flow anesthesia with high flow anesthesia and to investigate whether the advantages of low flow anesthesia during positive pressure ventilation can be combined with the laryngeal mask airway in paralyzed pediatric patients. METHODS: Thirty-one pediatric patients of ASA physical status 1 or 2 were studied and divided into two groups according to the fresh gas flow (FGF) in the breathing system; low flow group (FGF approximation 1 L/min, n = 17) or high flow group (FGF approximation 4 L/min, n = 14). Each respiratory parameter was measured when a steady state was reached at 20 min after induction. RESULTS: There were no significant differences of respiratory data between the two groups except that the inspired oxygen concentration was lower in the low flow group than in the high flow group. Hemodynamic changes with the laryngeal mask airway insertion were not statistically significant. CONCLUSIONS: A laryngeal mask airway is an effective airway device for low flow anesthesia as well as for high flow anesthesia in paralyzed pediatric patients.
