Stellate Ganglion Block for the Treatment of Adult Onset Still's Disease: A case report / 대한마취과학회지

A 31-year-old woman was referred to our pain clinic department under the diagnosis of an adult onset Still's disease. She had been suffering from high fever, skin rash, multiple arthralgia, morning stiffness and lymph node enlargement for 16 months. She had taken conventional medication with steroid and NSAIDs, but the symptoms were a remittent nature. And also, she complained of systemic side effects of corticosteroids. Stellate ganglion block with 0.25% bupivacaine was performed 67 times for the treatment of adult onset Still's disease and then, her symptoms were improved eventually. We could discontinue steroid and NSAIDs, laboratory data were satisfactory. As we experienced an adult onset still's disease improved with stellate ganglion block, we report this case with a review of the literature.

Airway Obstruction Immediately after Endotracheal Intubation for Removal of Cervico-Mediastinal Cystic Hygroma: A case report / 대한마취과학회지

Abrupt increase in the size of cervico-mediastinal tumor due to infection or spontaneous hemorrhage into cyst can induce severe tracheal compression and therefore sudden death. A 5 year old boy, who had a history of URI, had an enlarging cystic hygroma on the right side of the neck and anterior mediastinum. Under diagnosis of the cervico-mediastinal cystic hygroma, surgical removal was scheduled. After induction of anesthesia, intubation was done without any difficulty. A few minutes later, signs of partial airway obstruction were appeared. And within a very short period, total airway occlusion occurred. The tracheal tube was removed and manual ventilation was performed with positive airway pressure, but ineffective. We attempted to puncture cricothyroid membrane with 14 Gauge needle in order to ventilate manually. As soon as we puncture cricothyroid membrane, straw-colored fluid, not air, gushed out through a needle. After aspiration of about 200ml of cystic fluid, the obstructive signs disappeared and the patency of the airway was maintained. Intraoperatively, no more airway problems occured and vital signs were stable. And postoperatively, patient had no specific complications and discharged on the 7th day after operation.

Pneumomediastinum, Subcutaneous Emphysema, Pneumoperitoneum and Pneumoretroperitoneum after Nephrectomy: A case report / 대한마취과학회지

Pneumomediastinum, air within the planes of the mediastinum, occurs in a wide variety of clinical settings. In the perioperative period, pneumomediastinum is caused by various anesthetic and surgical complications, but may appear spontaneously. When pneumomediastinum occurs with no apparent cause, it is referred to as a spontaneous pneumomediastinum. The suggested mechanism of spontaneous pneumomediastinum is rupture of marginal alveoli due to increased intraalveolar pressure and dissection of air along the bronchovascular sheath into the mediastinum. Predisposing factors include raised intrathoracic pressure, as with coughing, vomiting, and Valsalva maneuvers. The auther's case is presented of pneumomediastinum, with subcutaneous emphysema, pneumoperitoneum, and pneumoretroperitoneum, occurring one day postoperatively, in a 26-year-old female patient who underwent nephrectomy under general anesthesia. The patient was treated conservatively with oxygen and had an uneventful recovery. The authors discuss the possible causes and its management with a review of the relevant literature.

A Comparison of the Effect of Intravenous Patient - Controlled Analgesia vs. Intramuscular P.R.N Opioid Regimen on Heart Rate, Blood Pressure, Rate Pressure Product, and Visual Analogue Scale following Abdominal Hysterctomy / 대한마취과학회지

Previous studies have shown that patient-controlled analgesia(PCA) provides effective pain control in the postoperative patient. To compare the effect of pain relief on postoperative sympathetic responses and myocardial oxygen consumption, 40 healthy female patients undergoing abdominal hysterectomy were chosen randomly. They underwent pain management with either intravenous patient-controlled analgesia(IV PCA) or intermittent intramuscular opioid(IM P.R.N) regimen. Pain intensity(VAS), heart rate, blood pressure, and rate pressure product(RPP) were measured at predetermined time intervals for postoperative 72 hours after measurement of preoperative baseline values. Comparisons were then made between the two groups and among individuals within each group. IV-PCA improved postoperative pain relief(P<0.05), but did not suppress efficiently the heart rate, blood pressure, and RPP indicating sympathetic responses and myocardial oxygen consumption when compared with M P.R.N regimen. These variables were increased immediately and/or 30 minutes following the operation in both groups when compared with preoperative baseline value (P<0.05). These results suggest that improved pain relief per se by IV PCA had no mjor influence on the suppression of sympathetic responses and myocardial oxygen consumption and these responses were exaggerated during first 30 minutes after abdominal hysterectomy.

Anesthetic Management of a patient with Primary Aldosteronism caused by Adrenal Adenoma / 대한마취과학회지

Increased and inappropriate production of aldosterone from the adrenal gland is known as primary aldosteronism and leads to sodium retention with hypertension, suppression of plasma renin, and hypokalemia and its manifestations. It is due mainly to a solitary adenoma, bilateral hyperplasia, or rarely an adrenal carcinoms. Primary aldosteronism due to an adenoma is usually treated by surgical excision. Preoper-ative managements include the correction of hypokalemia, volume derangement, and metabolic alkalosis with spironolactone and the trestment of existing hypertension. The authors report a case of unilateral adrenalectomy and anesthetic considerations during perioperative periods.

Malignant Hyperthermia during General Anesthesia / 대한마취과학회지

Malignant hyperthermia is a genetically transmitted, catastrophic, hypermetabolic syndrome that is induced by potent volatile anesthetics and/or depolarizing muscle relaxants. It is now well established that the pathophysiology is related to a malfunction of the intracellular calcium homeostasis in skeletal muscle. Morbidity has been correlated to the duration of symptoms. Dantrolene decreased release of calcium from the sarcoplasmic reticulum. We recently encountered a fulminant case during halothane anesthesia. Anesthesia was induced with thiopental and succinylcholine without jaw tightness or stiffness. After induction, tachycardia, arrhythmias, increased end-tidal CO2, and high body temperature were noted. Arterial blood gas analysis showed a severe, mixed acidosis. Intensive treatment with body cooling was immediately initiated. But dantolene could not be available. The patient died of renal failure and disseminated intravascular coagulation 41 hours after induction of anesthesia.
