  ABSTRACT: This paper discusses the efficacy and difficulty of the management of monitored anesthesia care (MAC) for inguinal hernia repairs using tumescent local anesthesia(TLA). Eighty patients were retrospectively divided into four groups (all n = 20) according to the drugs used; group P (propofol), group PF (propofol and fentanyl), group PFM (propofol, fentanyl and midazolam), group PR (propofol and remifentanyl). The four groups were analyzed in terms of the applied dose, airway use, wake-up test to determine whether hernia was repaired, postoperative pain and nausea. More propofol was administered in group P than in group PFM and PR. Although, airway was used for nine patients, there was no difference between the four groups. Postoperative pain and nausea also do not differ between the groups. One patient in group P showed unsuccessful repair with wake-up test. MAC shows a beneficial effect on inguinal hernia repairs under TLA. The rate of airway use was as high as eleven percent, and maintenance of the patients' airway requires attention. In terms of wake-up test, propofol combined with opioid administration may be more effective than propofol administration alone. There was no significant difference between the groups in pain and nausea, regardless at the use of fentanyl or remifentanil.

  ABSTRACT: A five-year-old boy with recurring tonsillitis and sleep apnea was admitted for tonsillectomy and tympanic membrane tubing. He presented with a history of bronchial asthma and hereditary spherocytosis without obvious cardiac failure symptoms. Anesthetic agents for induction included nitrous oxide, oxygen, and sevoflurane. Because oxygen saturation decreased immediately to 90%, tracheal intubation was performed. The patient began to wheeze. Sevoflurane concentration was increased but cardiac murmur (gallop), cold limbs and jugular vein distension were noted. Acute cardiac failure was diagnosed following a chest X-ray and cardiac echo showing an enlarged heart, CTR of 80%, left ventricular dilation, and contractile failure. Tympanic membrane tubing only was performed. Sevoflurane was discontinued and the patient was treated for the cardiac failure under an ICU oxygen tent. The patient was discharged when his general condition improved. He showed elevated levels of viral antibodies, suggesting myocarditis. Later he was treated for dilating cardiomyopathy before undergoing a heart transplant.
