To provide optimal obstetric anesthetic care, it is essential for the anesthetist to know well the maternal physiological alterations produced by pregnancy, labor and paturition, physiology and pharmacology of the fetal placental complex and how these are altered by analgesics and anesthetics (Bonica, 1972). Recently, the tendency to cesarean section has increased; the cesarean section rate was 8.1. (Lee et al., 1974) and 15% (Dripps et al., 1977). Choice of regional or general anesthesia for cesarean section depends on many factors. As, the paturient is considered to have a full stomach, regional anesthesia is advantageous. However, if the indication is fetal distress or maternal hemorrhage, the necessity for rapid delivery overrides all other considerations. For elective cesarean section the choice of anesthesia largely relates to patients condition and physicans preference, although the somewhat. longer time required for delivery in a repeated cesarean section may indicates regional rather than general anesthesia (Dripps et al., 1977; James et al., 1977). The problem of anesthetic management of cesarean section was fetal depression due to sedatives, analgesics and anesthetics during delivery. In emergency cesarean section, the major problem in general anesthesia is aspiration of gastric contents and in regional anesthesia it is hypotension. Regarding fetal and neonatal depression associated with anesthesia, the effects of general or regional anesthesia or. the neonatal neurobehavioral status have been reported by many authors (Standley et al., 1974; Tronick et al., 1976; Hollmen et al., 1978). Thus we have made a clinical analysis of anesthesia for 300 cases by random sampling among 1725 cesarean sections. including emergency and elective operations, performed from July 1973 to June 1978 in Severance Hospital at Yonsei University College of Medicine. Clinical analysis was made of frequency of cesarean section, age distribution, parity, indication of cesarean section, physical status (A.S.A. classification), premedication, anesthetic method, relationship between Apgar score and the type of anesthesia, relationship between induction to delivery time and one minute Apgar score, time to initial blood pressure drop after spinal anesthesia, blood loss, the methods of cardiopulmonary resuscitation of the newborn, perinatal mortality and neonatal neurobehavioral states. The result are as follows: 1) The incidence of cesarean action was 18.4 percent of total deliveries and the tendency is increasing. 2) One minute Apgar score in spinal anesthesia is better than in general anesthesia (0. 01 < p < 0.025). 3) Blood loss in spinal anesthesia (566+/-146 ml) is less than in general anesthesia(796+/-388ml). 4) Blood pressure showed a drop within ten minutes in 83 percent of cases after induction of spinal anesthesia. 5) Perinatal mortality of general anesthesia (3.9%) is more than spinal anesthesia (1.9%). Even though clinical results of spinal anesthesia seem to be more favorable than those of general anesthesia, from the above observation it may be concluded that choice of anesthesia for cesarean section depends on each maternal condition and only one anesthetic method should not be exclusively used.

PURPOSE: To compare the mean deviation (MD) between monocular and integrated binocular visual field (BVF). METHODS: Thirty-six patients with glaucoma in at least 1 eye were recruited for the present study. Seventy-two threshold sensitivities of the BVF were obtained without additional visual field test by the Best Location and Binocular Summation methods using the 2 monocular visual fields of central 30degrees. The MD of the BVF was obtained by comparison to the value distribution in the age-matched population with normal BVF. After defining the better eye with the better MD value from the 2 eyes, comparison of the MDs between individual eyes and the integrated BVF were assessed. In addition, the MDs between the integrated BVF and actual BVF were compared in 11 patients. RESULTS: In patients with a mean age of 58.7 years, the MD of the better eye was -2.3 dB, and the worse eye was -4.9 dB (p < 0.01). There was a significant difference between the 2 MDs derived from Best Location and Binocular Summation (-1.7 and -2.0 dB, respectively p = 0.045). The MDs according to BVF more improved than the better eye (p < 0.01 for both). There was no significant difference in MDs between integrated BVF and actual BVF (-1.9 vs -2.0, -2.3 vs -2.0, respectively p > 0.1). CONCLUSIONS: The integrated BVF more improved than the better eye. When providing guidance to glaucoma patients regarding therapeutic decisions considering the MD of IVF may be important.

PURPOSE:It is important to evaluate the healing process of avascular necrosis (AVN) involving femoral head after treatment. The purpose of this study was to assess the usefulness of pinhole bone scintigraphy in the AVN of femoral head after surgery. MATERIALS AND METHODS: We analyzed the changing pattern of pinhole bone scintigram in 21 femoral heads of 16 patients (14 lesions/11 male, 7 lesions/5 female, mean age: 39.4 yrs) before and after multiple drilling or vascularized bone grafting for AVN of the femoral head. In all patients, pre-operative scintigrams were obtained at 1 to 3 months before treatment and the first post-operative scintigrams were obtained at 1 to 3 months after treatment. All patients were followed for 2 to 4 years after operation. RESULTS: The findings of the pinhole scintigrams were divided into three patterns: 1) curvilinear, 2) scattered spotty and 3) undetermined. The 10 of 11 lesions with curvilinear pattern had good postoperative clinical and radiological follow-up findings. However, all 6 lesions with scattered spotty pattern showed poor postoperative findings, which necessitated total hip joint replacement. Of the 4 lesions with undetermined pattern, 2 required total hip joint replacement. There was significant difference in postoperative prognosis between the curvilinear and scattered spotty patterns (p<0.05). CONCLUSION: We conclude that the pattern of pinhole bone scintigram obtained within 1 to 3 months after multiple drilling or vascularized bone graft operation is a useful prognostic indicator in the AVN of femoral head.

Paroxysmal nocturnal hemoglobinuria(PNH) is a rare, acquired disease involving multiple hematopoietic lines. Characteristics of PNH are intrinsic hemolytic anemia, iron deficiency anemia and venous thrombosis. report a case of PNH with characterostoc MR and CT findings. The signal intensity of renal cortex was lower than that of medulla on both T1- and T2- weighted MR imaging. On T2 weighted MR images, the liver showed very low signal intensity but the signal intensity of the spleen was normal. On precontrast CT the attenuation of renal cortex was higher than that of renal medulla and the attenuation of liver was higher than that of the spleen. These findings of MR imaging and CT were the result from the deposition of hemosiderin in the cells of proximal convoluted tubules and transfusional hemosiderosis of liver.
