This is a case of cervical cord injury which is a rare complication of endotracheal intubation. A 32 year old muscular male with a short neck had a laparotomy for panperitonitis. He was tranfered to the recovery room after surgery, and the anesthetic procedure wase completed uneventfully. Endotracheal intubation was attempted on several occations on an emergency basis because of unexpected cyanosis associated with hiccups and vomiting in the recovery room. Therefore, his respiration was controlled by the respirator, but he was not able to breath spontaneously for several days. The condition was due to a cervical cord injury with signs of paralysis of the respiratory muscles and upper extremities. The mechanism and process was described.

Halothane is most easily blamed when a postoperative casef hepatitis occurs because it is most commonly used as an anesthetic agent and hepatitis has been intermittently reported for time. However, it is not easy to prove halothane induced the hepatitis clinically because there a long are many factors causing hepatitis. We had two cases of acute hepatitis developing following surgery. Case 1. A 49 year old male underwent surgery for femur fracture under halothane anesthesia. The preperative liver function tests were normal and the operation was uneventful. He developed epigastirc descomfor on the second postoperative day and jsundice with marked elevation of SGOT, SGPT, alkaline phosphatase and bilirubin on the 3rd day. Since the 7th postoperative day, the signs of acute renal failure with ascites became evident, therefore, dialysis was carried out. The died of acute respiratory and renal failure on the 20th postoperative day. We consider the nonA, nonB viral hepatitis infection as a possible cause in this case. Case 2. A 35 year old male had an operation for right femur fracture under repeated halothane anesthesia. On the 3rd day, he developed high fever of 39 degrees C. Liver function tests showed marked elevation of SGOT, SGPT, alkaline phosphatase and leukocytosis with eosinophilia, followed by gross jaundice. HBs Ag(-) and anti-HBs(+) were reported. He recovered gradually from the hepatitis and went home in good health on the 30th postoperative day. A possible cause of the hepatitis in this case was considered to be the halothane anesthetic.

Acid-base balances in the CSF have been reported by a number of groups during the past 20 years. The CSF contains only neligilbe concentrations of buffer anions other than HCO3(-). Acid-base balances in the CSF depend mainly on arterial PCO2 because arterial CO2 diffuses easily into the blood-brain barrier to form H2CO2 in the CSF. This study was primarily undertaken to observe the changes of pH, CO2 and HCO3(-) values in the CSF in the acute stage of hyperventilation. We have studied relatively healthy patients who were scheduled for surgery for cerebral aneuryams. Prior to induction of anesthesia, the radial artery was cannulated for and arterial line and blood samples taken and lumbar tapping was performed at the level of L3-4 using at 14 gause long needle, then a 18 gauze catheter was inserted through the needle. Pre-operative samples for gases were taken, then the patient was anesthetized and his repiration was controlled and maintained at the PaCO2 of 30 torr. The samples in both blood and CSF for gases were obtained at intervals of 15, 30, 45 and 60 minutes and observed and compared. The results were as follows: The PCO2 in CSF decreased as rapidly as the arterial PCO2 decreased by hyperventilation. The data obtained after hyperventilation of 45 minutes showed a significant decrease of CO2 value in the CSF as compared to the control group. The pH in the CSF increased as rapidly as the pH of the arterial blood. The arterial HCO3(-) decreased significantly in the groups of 15, 30 and 45 minutes and it was highly significant in the 60 minutes group, despite this the HCO3(-) in the CSF showed no significant changes in any of the groups. In conclusion as a result of this study, no visible metabolic compensation in the CSF for respiratory alkalosis was observed in an acute stage of hyperventilation.

Various anesthetic agents have been recommended for pheochromocytoma surgery. However, in general, no ideal anesthetic agent has been accepted as yet. The use of the well known agents, halothane still remains a contraversial issue for pheochromocytoma surgery. According to our experience and a review of the literature, it is strongly suggested that halothane is the anesthetic agent of choice among the anesthetic agents currently available. We believe that the incidence of arrythmia from halothane is not higher than that from other anesthetic agents and arrthmia is not caused primarily by halothane, but results mostly from endogenous catecholamines during surgery. In addition to these advantages, it is a rapid induction agent accompained by a peripheral vessel dilating effect. Lidocaine also is readily available to counteract the disadvantages of the arrythmic effect of halothane. We have had two uneventful cases of pheochromocytoma surgery. One was prepared with phenoxybeaxamine preoperatively and anesthetized with halothane. The other was not prepared with phenoxybeaxamine, but was anesthetized with halothane. The patient prepared with phenoxybeaxamine had prolonged hypotension for two days postoperatively and was treated with Neo-Synephrine drip. However, the patient wihout preoperative phenoxybeaxamine had no problem with his blood pressure post operatively. As a result of this experience, we believe the preoperative use of phenoxybeaxamine is not necessary, plus it also creates more problems with postoperative hypotension. Halothane can act as a vasodilator in place of phenoxybeaxamine during anesthesia. Therefore, halothane is currently the ideal anesthetic agent of choice without phenoxybeaxamine preparation when lidocaine is available.

Recently several reports have described the usefulness of meperidine as a sole agent for spinal anestaeaia. In this study, meperidine mixed with a 10% dextrose solution was used for a spinal anesthetic agent for Cesarean sections in twenty cases. The results from the meperidine spinal anesthesia were compared with lidocaine spinal anesthesia. The specific gravity was 1.043 with 5% lidocaine solusion and 1.029 with meperidine solution. Both were hyperbaric and very similar in baricity. Hypotension over 20% decre-ase in systolic blood pressure due to spinal aneshesia was found in nine out of 20 cases in the lidocaine group and eleven out of 20 cases in the meperidine group. A dose of ephed- rine used for hypotension was 14.+/-3.mg in the lidocaine group and 20.6+/-10.2mg in the meperidine group. The Apgar score was 10 in both groups at 5 minutes. The duration from the administration of the drug until the development of severe pain postoperatively was checked as 481.8+/-197.8 minutes in the meperidine group and 89.0+/-21.8 minutes in the lidocaine group (P<0.001) . As a result of thin study, it was concluded that meperidine can serve as an alternative agent for spinal anesthesia for a Cesarean section. The motor recovery from meperidine spinal anesthesia is shorter than lidocaine and the postoperative analgesic effect was very efficient and much longer than lidocaine, and no clinical signs of fetal depression with a good Apgar score were observed.

Intraspinal morphine anesthesis for open heart surgery was first publicized by Jeon early in 1986. We came to the conclusion that the anesthesia induced by an intraspinal morphine injection was satisfactory in anesthesia practice for open heart surgery and we have called this procedure, "Intraspinal Morphine Anesthesia". However, respiratory depression seemed to be most serious between 12~16hrs, after an intraspinal injection of morphine so that this technique is recommended only in patients who need controlled respiration for more than 12 hours because respiratory arrest occurs more commonly at that time. In other words intraspinal morphine anesthesia is absolutely not recommended in patients for simple operations. This study was undertaken to evaluate the effects of demerol injected in the subarachnoid space and to compare them with the effects of intraspinal morphine anesthesia. This attempt was made to take advantage of the rapid onset and short duration of demerol action for simple and short procedures. We had 32 cases scheduled for open heart surgery but those were all simple cases such as ASD and VSD in which controlled respiration was not expected to be needed. They were anesthetized mainly by intraspinal demerol and intravenous tranquilizers with 100% oxygen throughout the surgery. 1) The dosage of intraspinal demerol which ranged between 1~2 mg/kg did not seem to be proportional to the duration and potency of the drug. 2) Valium was administered intravenously to eliminate intraoperative awareness. Valium was preferred to Activan for simple cases. 3) The main action of demerol seemed to last 3~4 hours and no respiratory problems were observed 4 hours after the injection of demerol. 4) The onset of an anlgesic effect appeared at 5~7 minutes and the respiratory depression or arrest occuresd around10 minutes after the injection. 5) Cardiovascular dynamics appeared stable throughout the surgery except for transient bradycardia with mild hypotension whcih was seem occasionally. 6) Respiratory depression seemed to be no problem in the recovery room and ICU periods. 7)Somnolence lasts around 2~4 hours with no inadvertent resctions. 8) documented complications such as pruritus and voiding difficulty were not problems with the use of demerol for open heart surgery. 9) The aneshtesia induced by intraspinal demerol injection was satisfactory in anesthesia practice for simple cases. Therefore, we have called this procedure "Intraspinal Demerol Anesthesia". However, this technique sometimes is inconvenient in clinical practice because of its short action.

Balanced anesthesia is being equilibrated with the maintenance of light planes of anesthesia and the relatively free utilization of muscle relaxants to prevent untoward movement of the patient in response to surgical stimuli. However, muscle relaxants per se do not contributes to the state of hypnosis or analgesia. Therfore, awareness during modern anesthesia must be seriously taken. We have given anesthesia in 175 cases for cesarean section in order to investigate intraoperative awareness. Among the 175 anesthetic cases, 13 cases had awareness of pain and 19 cases had auditor awareness. Accordingly the total incidence of awareness in our investigation was 16% which was significantly high and should be considered in clinical anesthesia practice.

Voiding difficulty has been well documented as a complication after spinal anesthesia. This occurs somewhat more frequently after spinal anesthesia than after general anesthesia. However, the cause and mechanism of postspinal voiding difficulty has not been clarified, so in this study we have attempted to discover the mechanism of the voiding difficulty. Cystometry was performed on 30 healthy women who were scheduled for simple hystrectomy and the results were compared in three different groups. In the first group, cystometry was performed on 30 cases under only the premedication before the induction of anesthesia. In the second group, it waa performed on 14 cases under general anesthesia and in the 3 rd group, performed on 16 cases under spinal anesthesia. The results were as follows: 1) In the first group of 30 cases before anesthesia, the first voiding desire starts at approximately 150-250 ml (24 cases) and the average pressure of the bladder at the first voiding desire is approximately 5-10 cm H2O(19 cases). The volume at the maximum voiding desire is about 450-550ml(20 cases) and its pressure was 16-20cm H2O(12 patients). The average pressure tension curve of the cystometry was very similar to the normal one. 2) In the 2nd group of 16 cases under general anesthesia, measurement was not obtainable at the first and maximum voiding desire because they were under the effect of the anesthesia. The average pressure tension curve of the cystometry was lower than Group I (Fig. 1) and the critical volume which is designated as the volume at the point where the pressure of the bladder increased sharply in cystometry, was about 700ml which was larger than Group I. 3) In the 3 rd group of 16 cases, the cystornetry showed on the average pressure tension curve that the increase of the pressure was proportional to the volume in the bladder and no critical volume seems to be observed. It means that there is no contraction of the bladder muscle due to the paralysis of the sacral parasympathetic nerves which innervate the detrusor muacle of bladder. As a result of this study, we came to the conclusion that a cause of post-spinal urinary retension is the residual effect of local anesthetics prolonging the depression of the autonomic parasympathetic innervation system. These fibers from S2-S4 are very susceptible to analgesic solutions.
