A new benzodiazepine derivative, Rohypnol (Ro 5-4200), was used for management of general anesthesia with nitrous oxide, narcotics and muscle relaxants to evaluate the effect on the cardiovascular and respiratory system in 35 surgical patients. In each patient, we observed the blood pressure, pulse rate, minute volume and arterial blood gas analysis and also local effects, postoperative recovery state and amnesia. The results are as follows; 1) Induction dosage of Rohypnol was not constant as other benzodiazepines. 2) Rohypnol showed a little effect an the cardiovascular system. 3) The effects of Rohypnol on the respiratory system were negligible but slight depression was seen. 4) If respiration became shallower or apnea occured during induction with Rohypnol, it was preferred to use assisted or controlled ventilation with 100% oxygen. 5) It was thought better to give oxygen through a nasal catheter for prevention of decreased PaO2 in recovery room. 6) When we used the non-depolarizing muscular relaxants instead of S.C.C. for intubation, we observed that a significantly decreased amount of relaxant was needed for maintenance of general anesthesia.

Since 1966, Propanidid has been used not only for minor operative procedures but also as an induction agent. The present study was undertaken on 28 unselected cases from the daily operating schedule and blood gas analsis done before anesthesia and immediately after intubation with the aid of deporalizing muscle relaxants. Endotracheal intubation was performed intentionally preceding artificial oxygenation. The results of the blood gas study showed a mean PaO2 of 120. 2 mmHg, PaCO2-mean 41. 2 mmHg and pH-mean 7, 388 during respiratory depression following hyperpnea. As an induction agent, propanidid not only has no local complications but also gives smooth induction without excitatory phenomen and a rapid recovery. Further study on the interaction with nondeporalizing muscle relaxants is suggested.

This study was designed to evaluate the potential applicability of magnetic resonance imaging (MRI) for the diagnosis of acute renal vein thrombosis. Renal vein thrombosis was experimentally induced by surgical ligation of the left renal vein in a total of 21 rabbits. MRI was performed with a 0.5 Tesla superconductive magnetic system. Spin echo technique was used with varying TR and TE parameters. Spin echo images of the rabbit kidney were analysed for morphology and signal intensity. T1 and T2 relaxation times of the renal cortex and medulla were calculated from the images. After venous ligation, kidneys became enlarged. Low signal band along the outer medulla in T2 weighted images were characteristically shown from 1 hour to 3 days after ligation, Changes of cortex to medullar contrast (CMC) values were significant (p<0.05) in T1 - and T2- weighted images of the ligated side. T1 and T2 relaxation times were significantly prolonged (p<0.05) on the ligated side, both in the cortex and medulla from 1 hour to 2 weeks after the ligation, while T2 relaxation time on the contralateral side was significantly prolonged both in the cortex and medulla 2 weeks after venous ligation. The most useful MRI criteria for the diagnosis of renal vein thrombosis were enlarged renal size, and the low signal band along the outer medulla of ligated kidney. The relative intensity difference between cortex and medulla (CMC) in T1-and T2-weighted images, and T1 and T2 relaxation times were suggested to be the useful MR parameters for the diagnosis of acute renal vein thrombosis.

A variety of treatments has been used to correct long forehead and frontal alopecia. These include forehead reduction (scalp reduction), hair graft and flap transfer. Among these procedures, forehead reduction (scalp reduction) is the most simple and effective method. In this procedure, various fixation techniques of scalp flap to cranial bone are used to prevent retraction of the scalp. We used Sherlock (or Piranha) screw to anchor the scalp flap to cranial bone. Between August 1998 and May 2000, this technique had been performed for 37 patients. Average follow-up period was 15 months. For forehead reduction (scalp reduction), the scalp was elevated back to the occipital region through a pretrichial incision, and relaxation incisions of galea was made at a right angle to the vector of advancement. The Sherlock (or Piranha) screw was fixed to the cranial bone. The entire scalp was then repositioned anteriorly, advancing the hairline caudally and shortening the forehead. Retraction of the scalp was prevented by anchoring the galeal fascia to the cranial bone using Sherlock (or Piranha) screws. This technique allows sufficient advancement of the scalp and a tension-free closure. Postoperatively scar widening was less than that of other methods. There were not any infection, hematoma, hair loss nor permanent paresthesia on scalp. In 2 cases, screws were palpable and we removed a screw for 1 case. Advantages of using Sherlock (or Piranha) screw are that the procedure is easy and simple, and sufficient advancement of the scalp, tension-free closure, and less scar widening can be achieved. Disadvantages of this procedure include cost of screw and palpability of screw. In conclusion, by using Sherlock (or Piranha) screw, the procedure was simple and we could get aesthetically good results.

A 42 year-old male with a history of multidrug-resistant pulmonary tuberculosis suddenly developed massive hemoptysis. Embolization of a bronchial artery branch and the collateral systemic arteries did not resolve the recurrent bleeding. Spiral computerized tomography(spiral CT) of the chest showed contrast enhanced nodules within a large cavity at the left lower lobe in the arterial phase suggesting a Rasmussen aneurysm. A pulmonary angiogram showed abnormal vascular nodules at that site. Coils were deployed at both the proximal and distal vessels of this aneurysmal sac for embolization. Transcatheter arterial embolization is a safe and effective means of controlling bleeding from this pulmonary arterial pseudoaneurysm. Here we report a case of a Rasmussen aneurysm diagnosed by spiral CT, which was successfully treated by pulmonary arterial embolization with a coil.

Sine 1961, Dr. Safar postulated the new form of patient, so called "progressive patient care", the hospital service in all countries are fashioned with intensive therapy unit. Particulary the- World Federation Society of Anesthesiologists who have discusincerly at several International congress. we were interested from the literature and visited England, Denmark, United States. and Japan. Of course in Korea, the intensive therapy unit developed from the recovery room and is thus intimately oonnected with anesthesiologists. Here we reviewed with literature and introduced the activities af the intensive therapy unit of Hanyang University Hospital from May 1972 to October 1973, from the point view of the definition, building design, location, capacity, equipment, staff organization and charge of patient, several problems and regulations. Furthermore we recommended with the following new ideas for establishment in hospital of an intensive therapy. unit. a. The design should be arranged on the same floor (OR-RR-Anes.-1TU) and in central part of building. b. Several isolation rooms should be made in 1-T-U. c. One central monitoring system will serve each units. d. The 1-T-U equipment should be used with wall trolly system. e. The regulations of 1-T-U should be noted and advocated by all hospital members. f. The beds in 1-T-U should be arranged with open system.
