The cardiovaseular response evoked by tracheal intubation was observed in 69 patients undergoing elective surgery in whom anesthesia was induced with group A, B and C induction agents. Sixty nine ASA class 1 or 2 surgical patients were divided into three groups. Group A: thiopental 5 mg/kg (control) Group B: thiopental 2 mg/kg with midazolam 0.1 mg/kg Group C: midazolam 0.2 mg/kg Systolic and diastolic blood pressure, mean arterial pressure, heart rate and loss of eyelid reflex were measured in each group. There was a little difference in the cardiovascular changes between group A and C. But there was not a significant difference between group A and B and also between group B and C. The measured time until loss of eyelid reflex of the group C (55±30 sec) was considerably longer than other groups (Group A: 10±3 sec, Group B: 37±13 sec). The incidence of venous complication in three groups was low. Pain on injection and posto- perative nausea and vomiting was noted in one patient of the group A and B respectly, but no patient in the group C. There was no significant difference in the incidence of the postoperative local venous complication. On the whole, these results suggest that the difference between midazolam and thiopental had no apparent hemodynamic change. From the above results, both midazolam alone and midazolam combined with thiopental may be useful agents for induction of anesthesia.

We present a retroprospective study of traumatic spinal fractures. There were 83 cases of trumatic spinal fracture admitted to Chosun university hospital through the emergency medical center from January, l995 to December, 1995. The results were a.s follows; 1) In the methods of transportation, the 119 ambulance was the most comrnon and followed by the hospital ambulance, the 129 ambulance and the private vehicles in decreasing order. 2) Prehospital treatment was done in only 19 cases. 3) Associated injuries were developed in 93 cases from the 51 patients. Head injury was the most common and followed by the long bone fracture, the pelvic bone fracture and the abdominal injury, the multiple rib fractures with hemopneumothorax and the small bone fracture in decreasing order. 4) Fifty-nine percent of traumatic spinal fractures occurred at the age group of 20-40. Motor vehicle accidents were the leading cause of traumatic spinal fractures. 5) The most common site of traumatic spinal fracture is the thoracolumbar junction and lumbar spine and followed by cervical spine, thoracic spine in decreasing order. 6) 3.6% of all spinal cord injuries had resulted in complete and 16.9% in partial loss of sensation.

Propofol, by virtue of its favorable pharmacokinetic profile, has already achieved considerable popularity for induction and maintenance of anesthesia for short duration surgery. Short acting opioids are often used as part of balanced technique. Because of their similar pharmacodynamic characteristics(rapid onset and short duration of action), it seems that propofol and fentanyl would be a adequate complementary agents for total intravenous anesthesia when used in combination. The purpose of present study was to access the effect of fentanyl on the changes hemodynamic and respiratory responses when used in combination with propofol. Eighty patients of ASA grade l or 2 scheduled to undergo minor gynecological, abdominal and orthopedic procedures were allocated randomly to 4 groups. Group A, C was induced with pentothal sodium or propofol alone respectively and maintained using 60% nitrous oxide in oxygen. Cardiovascular and respiratory parameters were checked before induction, and 2, 4, 6, 8 minutes after injection. The results were as follows 1) Changes in mean arterial pressur, after 2 minutes were more significantly decreased in propofol with fentanyl group than propofol alone. 2) Changes in heart rate Minimal changes in propofol group, but showed significantly decrease in propofol-fentanyl group. 3) Resipiratory changes Propofol-fentanyl group produce a more frequent, long standing apnea than other group. 4) Side effect. Excitatory effects, and pain on injection were more frequent in propofol group than pentothal sodium group. Nausea, vomiting were more frequent in pentothal sodium group than propofol group.
