Korea is regarded as a country that provides a high level of medical services despite a low burden of public health insurance premiums. However, patients face the burden of covering the costs of medical services that are not covered by health insurance, and providers face difficulties because the price of the medical service guaranteed by the health insurance system is very low. In this situation, the government is trying to expand health insurance coverage in the form of the ‘preliminary coverage system’ also known as the ‘selective coverage system’. In this system the government sets the price for a particular health care service not covered by health insurance and then the patient pays for the majority (50% to 90%) of the cost. Although it is possible to manage information about the amount of medical service usage at the national level through this system, it still places a high economic burden on patients with low incomes. In addition, since medical providers are forced to receive uniformly undervalued prices, specialized technologies that have been optimized by medical research institutions are threatened with extinction. Therefore, the preliminary coverage system needs to be reviewed before implementation of expanded coverage within this framework. First, the concept of essential medical care should be established. Based on this concept, the percentage of the cost to be paid by patients should be derived. If the preliminary coverage system is applied to medical services that are not covered by health insurance, a reasonable classification system should be developed and applied along with pricing considering customary market prices.

Dexmedetomidine is a new selective alpha2-adrenoreceptor agonist that can be described as a useful, safe adjunct in neuroanesthesia and neurocritical care practice. This alpha2-adrenoreceptor agonist offers a unique "cooperative sedation" +/- anxiolysis and analgesia without respiratory depression. Cerebral effects are generally consistent with a desirable neurophysiological profile, including neuroprotective characteristics. In addition, sympatholytic and antinociceptive properties allow for hemodynamic stability at critical moments of neurosurgical stimulation. This paper reviews the pharmacokinetic profiles and current clinical uses of dexmedetomidine in the area of neurosurgery patient care.

Perioperative care process in a hospital is considerably complex, involving multiple subprocesses, healthcare professionals, and systems in support of surgical care. The perioperative process is often the primary source of hospital admissions, driving the dominant part of hospital margins and accounts for a major part of all adverse events occurring in hospitals. The recent trend stresses the importance of adopting patient-centered and quality-proven care in many medical fields. Further, the emphasis on changing from fee-for-service to fee-for-value is increasing. These changes present challenges to anesthesiologists who play a central role in perioperative medicine.Current Concepts: Anesthesiologists are in contact with many surgeons and patients and are positioned to improve clinical outcomes. They need to have up-to-date, evidence-based knowledges on perioperative clinical management and know-how to apply, organize and practice them into efficient pathways for optimal outcomes. To accomplish such purposes, anesthesiologists need to acquire communication skills to reason and convincing related personnel including surgeons and patients.Discussion and Conclusion: The recent changing climate of perioperative medicine calls upon anesthesiologists to acquire knowledges driving quality care and demands the application of communicative skills to accomplish the required tasks.

Ankylosing spondylitis is a chronic and systemic disease involving the axial skeleton. In patients with involved cervical spine ankylosing spondylitis, endotracheal intubation by direct laryngoscope may be difficult because they have a limitation of cervical movement and anatomical anomalies. We experienced the evaluation of thirteen patients with involved cervical spine ankylosing spondylitis by the Mallampati classification, Cormack and Lehane grade, thyromental distance and orolaryngeal angle. By Mallampati class and Cormack and Lehane grade, patients were almost class 3 or 4. Thyromental distance was 5.3 +/- 0.4 cm, and orolaryngeal angle was 90.4 +/- 8.0o.

BACKGROUND: The alpha2-agonist clonidine is an adjunct in general anesthesia. Clonidine constricts cerebral arteries and decreases cerebral blood flow (CBF), but does not alter cerebral metabolic rate (CMR). Thus cerebral ischemia is possible due to CBF/CMR imbalance. This study was designed to prove the effects of clonidine bolus up on CBF and CO2 reactivity in desflurane anesthesia. METHODS: Thirty patients were divided into a clonidine group (n = 15) and a control group (n = 15). Anesthesia was induced with thiopental and pancuronium, and maintained with 50% N2O/O2/ Desflurane. The jugular bulb was cannulated to measure jugular bulb oxygen saturation (SjO2). MAP and SjO2 were measured after induction, after clonidine (2 microgram/kg) or normal saline administration and during hyperventilation. RESULTS: After clonidine administration, MAP decreased from 95.7+/-9.8 mmHg to 81.1+/-6.3 mmHg and was 79.9+/-5.0 mmHg during hyperventilation. In the control group, the corresponding MAP values 95.7+/-9.8 mmHg, 81.1+/-6.3 mmHg and 79.9+/-5.0 mmHg. After clonidine administration, SjO2 was decreased from 84.7+/-3.7% to 81.1+/-5.2%, and was 71.5+/-8.4% during hyperventilation (P = 0.003, P = 0.000) and in control group, there were 95.7+/-9.8%, 81.1+/-6.3% and 79.9+/-5.0%, respectively. CO2 reactivity was expressed as a change of SjO2 per unit change of PaCO2, 1.15+/-1.19%/mmHg versus 1.43+/-0.98%/mmHg (P = 0.49). CONCLUSIONS: During desflurane anesthesia, clonidine-induced constriction of the cerebral arteries was demonstrated but CO2 reactivity was well preserved.

Freeman-Sheldon syndrome is a rare congenital myopathy principally characterized by facial and skeletal abnormalities. We report a case of a Freeman-Sheldon syndrome in 12-year-old girl correction of undergoing kyphoscoliosis under somatosensory evoked potential monitoring. She had a characteristic appearance of Freeman-Sheldon syndrome such as hypoplastic alae nasi, high narrow palate, marked microstomia with pursed lips and clenched fingers. On arriving at the operating room, she was intubated by awake nasotracheal intubation with fiberoptic bronchoscopy and anesthetized with propofol and fentanyl.

BACKGROUND: The combination of propofol and alfentanil for nonrelaxant intubation produces hypotension and bradycardia. N2O, a commonly used inhaled anesthetic, has been known to augment the anesthetic depth in propofol anesthesia. Conversely, N2O was reported to increase the incidences of opioid-induced cough and rigidity. This study was designed to evaluate the effect of additional N2O on propofol requirement and intubating conditions. METHODS: Eighty healthy premedicated female patients were divided into N2O group (n = 40) and non-N2O group (n = 40). In each group, they were randomly assigned to four subgroups according to the propofol dose (1.0-2.5 mg/kg). With or without N2O (FiN2O = 0.5), propofol and 30mug/kg of alfentanil were administered during the induction of anesthesia. Expired concentrations of N2O were measured. Intubation was the attempted and intubating condition was scored (0-6). Incidences of cough and rigidity were also recorded. Dose of propofol for smooth intubation (score > 5) was analyzed and compared between groups. The conditions for smooth intubation were analyzed with variables (expired concentration of N2O, dose of propofol, age, incidences of hypotension, bradycardia, cough and rigidity) by logistic regression. RESULTS: The expired concentration of N2O was 33.0-3.8%. Propofol ED50 for smooth intubation was 1.67 mg/kg (1.26-2.19) in the N2O group and 2.27 mg/kg (1.78-3.47) in the non-N2O group. A smooth intubating condition was correlated well with increased concentrations of N2O and doses of propofol and inversely correlated with incidences of cough and rigidity. However, we failed to prove a significant difference in incidences of hypotension, bradycardia, cough and rigidity between the two groups. CONCLUSIONS: We cannot reduce the propofol requirement for smooth intubation without relaxant by using N2O. The success rate of intubation was increased by additional N2O.

The purpose of a conculation is to seek the opinions and advice of those whom we recognize to be more expert in a particular field of medicine than we are. Most surgeons regard the anesthesiolgist as a conculatant. Thus we analyzed 308 cases of interdepartmental consulatation submitted to our department from June 1991 to Novermber 1991. All case were elective ones and emergent cases were excluded. The analysis were as follow. 1) The overall conculation rate were 11.5%. 2) The highest rate of consultation were requested from orthopedic surgery department(29.9%) followed by ophthalmology department(25.0%), neurosurgery department(24.6%) and urology department(13.4%). 3) Male was 42.8% and female was 57.2%. 4) Most requestered problem was hepatic diseases including elevated transaminase, hepatitis and liver cirrhosis(35.1%) and then cardiovascular problem was 20.5%. 5) Because of our opinion, 22 cases were postponed. 6) Consultation rate increased according to advancing of age.
