The incidence of conjoined twins is so rare that few anesthesiologists have an opportunity of managing them. Especially in Korea, there are only a few reports describing the anesthetic management for surgical separation of newborn conjoined twins. We experienced the successful anesthetic management for surgical separation of thoraco-xiphopagus conjoined twins without any particular problems. After applying the noninvasive monitors (ECG, pulse oximeter), one of the twins (twinA) with congenital heart disease was administered with intravenous ketamine for induction of anesthesia and intubated without neuromuscular blocker. Anesthesia was maintained with N2O-O2 and hand ventilation using Mapleson D breathing circuit. After maintaining airway of the twinA, the twinB was intubated and maintained with the same manner. Eighteen days after the separation procedure, the twinA with congenital heart disease died and the other one, twinB has been alive with normal growth and development.

STUDY DESIGN: A prospective clinical study with radiologic assessment was conducted. OBJECTIVES: To analyze the height changes of the intervertebral disc and neural foramen and width changes of the neural foramen after anterior lumbar interbody fusion and posterior fixation in the lumbar spine. SUMMARY OF LITERATURE REVIEW : Anterior lumbar interbody fusion distracts the height of the intervertebral disc and neural foramen and the width of the neural foramen. MATERIALS AND METHODS: Minimal anterior lumbar interbody fusion and posterior fixation were performed in 20 cases from January 1999 to January 2001. The measuring factors were the height of the anterior and posterior discs, and the height and width of the neural foramen, measured with a caliper in 1mm reconstructive, computed tomography, sagittal images before and 6 months after anterior lumbar interbody fusion. The factors were independently measured by three different persons. RESULTS: The height of the anterior and posterior discs was increased by mean 32.2% and 40.5%, respectively. The height of the right and left neural foramen was increased by mean 15.7% and 18.3%, respectively. The width of the superior, middle and inferior neural foramen was increased by mean 20.6%, 30.3% and 38.6%, respectively. There were significant increases in all measuring factors after minimal anterior lumbar interbody fusion. CONCLUSIONS: Minimal anterior lumbar interbody fusion significantly increased the height of the anterior and posterior intervertebral discs, and the height and width of the neural foramen, and produced neural decompression.

BACKGROUND: Intrathecal (IT) neostigmine produces analgesia in animal and human. This study was designed to evaluate the efficacy and safety of IT neostigmine for post-cesarean section analgesia. METHODS: Forty-five women undergoing cesarean section under spinal anesthesia were randomly assigned into 3 groups to receive; normal saline 0.2 ml, or neostigmine 12.5 microgram, or neostigmine 25 microgram intrathecally with 0.5% hyperbaric bupivacaine 12 mg. Degrees of sensory and motor blocks, maternal hemodynamic changes, and side effects were recorded. Apgar scores and umbilical vein blood gas analysis (UVBGA) were checked for evaluation of fetal status. Postoperative analgesia was provided by intravenous patient-controlled analgesia (PCA) using fentanyl 500 microgram and ketorolac 150 mg in 100 ml. Pain scores with 10-cm visual analogue scale (VAS), time to first PCA use, cumulative PCA consumptions, and side effects were assessed at 1, 2, 4, 8, 12, 24, and 48 hr after IT injection. RESULTS: There were no significant differences among the three groups in characteristics of spinal anesthesia, maternal blood pressure and heart rate, Apgar scores, and UVBGA data. Compared to saline group, IT neostigmine significantly prolonged time to first PCA use and decreased 24 hr- and 48 hr-PCA consumptions (P<0.05). Pain scores in neostigmine groups were significantly lower than those in saline group for first 4 hr after which there were no differences among the three groups. There were significantly higher incidences of nausea and vomiting in neostigmine groups than in saline group. CONCLUSIONS: These data indicate that IT neostigmine can be an alternative postoperative analgesic without adverse fetal effects for cesarean section. However, high incidence of nausea and vomiting seem to limit its clinical usefulness. Further studies are necessary to enhance its analgesic effects and to decrease its adverse effects.

Hemodynamic variables in 8 verapamil pretreated patients(the verapamil pretreated group) were compared with those in 10 patients without pretreatment(the control group) during nitroglycerin(NTG) induced hypotension under halothane-N2O anesthesis. The results were as follows: 1) In the control group, there were statistically significant decreases in mean arterial pressure (MAP)(25%), pulmonary arterial pressure(PAP)(32%), pulmonary capillary wedge pressure(PCWP)(30%), central venous pressure(CVP)(33%), but the heart rate(HR), cardiac output(CO), cardiac index(CI) and stroke volume index(SVI) remained unchanged. After discontinuance of NTG, all parameters returned to baseline levels. 2) Verapamil alone produced a small decrease in MAP(6%) and CVP(9%), but other hemodynamic values did not change. 3) In the verapamil pretreated group, there were significant decreases in MAP(23%), PAP(30%), PCWP(27%), CVP(20%), SVR(24%) and PVR(31%), but HR, CO, CI, and SVI remained unchanged. 4) These results indicated that verapamil did not significantly affect the hemodynamic response to NTG under halothane-N2O Anesthesis.

BACKGROUND: Hypertension and tachycardia usually accompany laryngoscopy and tracheal intubation. Topical and intravenous lidocaine are used in an attempt to blunt these potentially adverse hemodynamic responses, but these effects of lidocaine are controversial. The purpose of this study is to evaluate whether intratracheal nebulized lidocaine and/or intravenous lidocaine attenuate circulatory stimulating response to tracheal intubation. METHODS: Sixty patients, ASA physical status I, scheduled elective surgery, were randomly assigned to receive a preintubation dose of either 5 mL of normal saline intravenously, 4 mL of 4% lidocaine by intratracheal nebulizer, 1.5 mg/kg of 2% lidocaine intravenously, or 4 mL of 4% lidocaine intratracheal nebulizer and 2% lidocaine of 1.5 mg/kg intravenouly. Induction of anesthesia was accomplished with 5 mg/kg of thiopental IV, and 1 mg/kg of succinylcholine was given. Laryngoscopy and intubation was performed, and anesthesia maintained with 2% enflurane in 50% nitrous oxide in oxygen. Blood pressure and heart rate were recorded at preinduction, after induction, and every minute until 5 min after intubation. RESULTS: Intratracheal nebulized lidocaine and/or intravenous lidocaine were effective in attenuating increases in systolic pressure with no detectable difference between them, and failed to attenuate increases in diastolic pressure and heart rate. And significant decrease in systolic pressure 3 min after intubation was detected in intratracheal and intravenous lidocaine group. CONCLUSIONS: These data suggest that intratracheal nebulized lidocaine or intravenous lidocaine is effective in attenuating increase in systolic pressure to tracheal intubation, but intratracheal and intravenous lidocaine has not synergistic effect.

The purpose of this study was to evaluate the shock absorbing effect of 4 restorative materials and intramobile connector. The damping effect of four restorative materials used to veneer test crown rigidly connected to IMZ implant and subjected to an impact force was measured. These materials included a gold alloy(stabilor G) : a noble metal ceramic alloy(Degudent H) : porcelain(Duceram) : composite resin(Dentacolor). In addition, this study compared damping effect of same restoretive materials after using polyoxymethylene intramobile connector(POM IMC). The result of this study suggest that : *In case of using metal IMC 1. Veneered composite resin(group IV) reduced the impact force by 75%, when compared to an equivalent thickness of porcelain(group III). Group IV reduced the impact force by 87% and 89%, respectively, when compared to Stabilor G(group I) and Degudent H(group II). 2. The impact force recorded was higher for the alloy with the higher elastic modulus.(Stabilor G, group I, Young's modulus 107 Gpa, versus Degudent H, Group II, Young's modulus 95 Gpa) 3. It took the longest time for composite resin veneered group(IV) to reach to peak force when compared group I, II, III. *In case of using POM IMC 4. The mean impact force recorded were reduced by 79%(group I), 78%(group II), 69%(group III), 84%(group IV), respectively, when compared to using metal IMC. 5. The time required to reach the peak force were increased by 78%(group I, II) 87% (group III), 34% (group IV), respectively, when compared to using metal IMC
