The treatment of tibial shaft fracture has become one of the most controversial subjects in orthopedic surgery. Comminuted, segmental and rotationally unstable fractures or bone defect at fraction site have problems of the fixation. The interlocking nail solve these problems. We have experienced 8 cases of the tibial shaft fractures treated with interlocking nail from 1986 to 1988. Authors analyzed these cases and out own clinical study. The results were as follows. 1. The average bone union rate was about 15 weeks. 2. The interval between operation and crutch walking was 4.3 weeks. 3. The merits of this operation were the short hospitalization and early adaptation of social activity. 4. The advantage is be able to do early ambulation without following muscular atrophy or joint stiffness. 5. The results were assessed on clinical examination and radiographic appearance by Hamza et al. An excellent results were 7 cases and good result was 1 case.

BACKGROUND: The large hemodynamic response induced by laryngoscopy and endotracheal intubation may cause serious cerebral complications. This study was performed to evaluate the effects of intralaryngotracheal 10% lidocaine spray on hemodynamic responses to endotracheal intubation for patients with a cerebral aneurysm. METHODS: Sixty patients with a cerebral aneurysm were randomly divided into three groups by lidocaine administration methods before endotracheal intubation: Group 1 (Control, 2% lidocaine 1.5 mg/kg, intravenous injection); Group 2 (10% lidocaine 1 mg/kg, intralaryngotracheal spray); Group 3 (10% lidocaine 1.5 mg/kg, intralaryngotracheal spray). Anesthesia was induced intravenously with midazolam (0.02 mg/kg) and thiopental sodium (2 - 3 mg/kg), and then maintained with 50% nitrous oxide in oxygen and 1.0 vol% isoflurane. Blood pressure and heart rate were measured preinduction, before laryngoscopy, immediately after epiglottis elevation, immediately after intubation and 3 minutes after intubation. Data were compared and analyzed within and between groups. RESULTS: Immediately after intubation, the increase in blood pressure and heart rate were blunted significantly in the groups 2 and 3 compared to the intravenous lidocaine injection group (P < 0.01). However, there were no significant hemodynamic changes between groups 2 and 3. CONCLUSIONS: The elevation of blood pressure and heart rate after endotracheal intubation can be prevented by intralaryngotracheal spray of 1 mg/kg of 10% lidocaine 3 minutes before endotracheal intubation.

BACKGROUND: We experienced unintentional hyperventilation during mechanical ventilation in pediatric general anesthesia. It is very difficult to decide respiratory rate or tidal volume with a patient's condition for adequate ventilation while respiratory gas monitoring is unavailable in many cases. Therefore, we studied to find a proper respiratory rate (RR) with a fixed tidal volume during mechanical ventilation in general anesthesia. METHODS: We studied 70 children weighing 10-30 kg during general anesthesia. An endotracheal tube was selected according to 3.5+age (yrs)/4. After intubation with midazolam, thiopental sodium and succinylcholine, mechanical ventilation was applied: tidal volume 8-10 ml/kg, peak inspiratory pressure 15-20 mmHg, RR 20 (infant), 18 (under 3 yrs), 16 (under 5 yrs), 14 (above 5 yrs) breaths/min. We adjusted the RR for a PetCO2 30 33 mmHg and arterial blood gas analysis was done 30 minutes each change. We calculated the RR for a PaCO2 of 36 mmHg according to the equation: RR (applied) = estimated RR estimated PaCO2/ideal PaCO2. In addition, the linear regression was analyzed between the age and RR. RESULTS: The estimated regression for RR using Pearson's correlation coefficient was as follows: RR = 19.25-0.07Xage (month). CONCLUSIONS: The equation (RR = 19.25-0.07Xage [month]) could be an index for safe ventilatory management without severe hyper- or hypo-carbia in the pediatric general anesthesia.

BACKGROUND: The recent expansion of knowledge about various ABO alleles has led to the need for a comprehensive measure to cover the numerous polymorphisms dispersed in the ABO gene. A few studies have examined the diversity of the O allele compared to A or B subgroup alleles, resulting in antigenic changes. This study investigated the relationship between the serologic and molecular genetic characteristics of the O alleles in the Korean population. METHODS: One hundred and five samples from healthy blood group O subjects were selected randomly. The isoagglutinin titer was measured using a tube agglutination and gel microcolumn assay. The ABO alleles were analyzed by sequencing exons 6 and 7 of the ABO gene. When the origin of a heterozygous nucleotide sequence was ambiguous, it was separated into a single allele using mono-allele amplification or cloning. RESULTS: The median IgM isoagglutinin titer was eight. In contrast, the median IgG anti-A and anti-B isoagglutinin titers were 64 and 32, respectively. The IgG isoagglutinin titer showed a significant increase with age (P<0.0001). Six O alleles were observed in 105 blood group O populations by sequencing. The O01 and O02 alleles were common (0.57, 0.36). Three rare O alleles (O04, O05, and O06) and one novel non-deletional O allele were found. CONCLUSION: The distribution of isoagglutinin titers of blood group O and the genetic frequency of O alleles in this study would form the basis of the development and interpretation of ABO genotyping and serologic workup in the Korean population.
