Scapholunate advanced collapse (SLAC) deformity most often occurs with chronic rotary scaphoid instability from scaphoiunate ligament tear and scaphoid fracture. Prior to 1984 when Watson HK reported his concept on SLAC wrist deformity, the most popular procedure for this pathology was scaphoid implant arthroplasty with or without midcarpal fusion. We have reviewed 15 cases of SLAC deformity treated with scaphoid excision and midcarpal fusion from 1984 to 1993. Among them, scaphoid implants made of silicone were inserted in 4 cases. Scaphoid implant arthroplsty without carpal fusion has been excluded. The mean period of follow-up was 8.8 years and the mean age of patients was 47.5 years. Males and right wrists were predominant. Wrist motion was 56% and grip power was 71% of the normal opposite side. On the average overall, 8 patients had no pain and 7 patients had mild pain. The grade of pain was minimal, 0.5 in grade (Rating system: no pain-0, mild- 1, moderate-2, severe-3). However, all of the 4 cases of limited carpal fusion with a scaphoid implant developed silicone particulate induced synovitis and pain. The procedure appears to be effective in maintaining function of the hand with minimal pain up to 5.8 years. However, silicone scaphoid implant appears not to be necessary and is not recommended with a limited carpal fusion for this pathology.

Motor evoked potentials(MEP) have been recently introduced as intraoperative monitoring of descending motor pathways. Transcranial electrical or magnetic MEP have been using clinically, but there are still some limitations of using in operating room. Furthermore, according to anesthetic regimens, MEP responses vary significantly. The authors observed the effects of the various anesthetics (thiopental, fentanyl, ketamine, nitrous oxide and isoflurane) on electocortical MEP in a patient who had been previously undertaken electrocortico-graphic grid insertion operation for seizure monitoring. Electromyographic responses were recorded from contralateral arm flexor and extensor using needle type electrode. Most anesthetics except ketamine decreased the amplitude of MEPs reversibly and there were differences in electromyographic responses according to measuring compound muscles.

The neuromuscular blocking effect of pipecuronium was evaluated in 35 patients under N2O-O2-isoflurane anesthesia with visual and/or tactile counts for the twitch of the adductor pollicis muscle in response to train-of-tour(TOF) stimulation of the ulnar nerve at the wrist. Group I, II and III were classified according to the initial dose of pipecuronium of 50, 80 and 100ug/kg, respectively. The additional dose, 30 ug/kg, was given in all three groups when the first twitch of TOF(T) reappeared. The onset time in Group I, II and III was 361.4+/-98.6, 218.7+/- 80.8 and 239.0+/-73.7 seconds, respectively. The onset time in Group I was significantly slower(p<0.005) than those in the other groups. All three doses of pipecuronium provided good to exceUent intubating condition in about 4 to 6 minutes after the administration of the initial dose. The time interval from the disappearance of T1 to the reappearance of T1 was 39.0+/-20.8 min in Group I, which was significantly longer(p<0.05) in Group II(67.7+/-26.4 min) or III(63.8+/-20.8 min). The cumulative effect of pipecuronium was evaluated by comparing the mean time intervals of an additional dose to the succeeding ones. The intervals between additional doses were independent of the size or duration of the initial dose. There were no significant differences in the intervals between additional doses. Heart rates, rhythms and mean arterial blood pressures were not significantly changed in any groups following the administration of pipecuronium In conclusion, pipecuronium bromide can be recommended as a long-acting neuromuscular blocking agent with an absence or minimum of cumulative and cardiovascular effects for patients in whom a long operation is scheduled and the cardiovascular stability is required.

The retrograde microorganismal colonization in the pharynx from stomach may cause the nosocomial pneumonia and that may be more likely when the gastric pH is relatively high. We tried to find out the relationships between the gastric pH and the incidence of nosocomial pneumonia with twenty patients intubated for longer than 48 hours at ICU. We achieved following results: 1) The incidence of the nosocomial pneumonia was twenty percent. 2) All the patients developed nosocomial pneumonia showed the gastric pH above 4.0. 3) In the patients intubated for longer than 5 days, the incidence of nosocomial pneumonia was 33.3% in contrast to 9.0% for less than 5 days. 4) With the sputum culture, the incidence of colonization was higher in the patients with gastric pH above 4.0 than that in the patients with gastric pH below 4.0(84.6% vs 58.1%). 5) With regard to the duration of intubation, the incidence of colonization was higher in the patients intubated for longer than 4 days than that in the patients intubated for less than 4 days(90% vs 50%). 6) The most common pathognomic organisms were astreptoccus and Pseudomonas aeroginosa. It is conculded that the nosocmial pneumonia might develop more frequently in the patients with gastric pH above 4.0 than in the patients with gastric pH below establishment of the relationship between the treatment of the stress ulcer and the nosocomial pneumonia.

Continuous assessment of arterial oxygenation is important in the clinical management of critically ill patients. Analysis of arterial blood gas is reliable but is invasive and only provides intermittent informations. In order to determine the accuracy of pulse oximeters in ICU patients, arterial oxygen saturation was measured in 58 patients in ICU using two kinds of pulse oximeters (Ohmeda, CSI), while simutaneously analyzing arterial blood gases. The relationship between the pulse oximeters saturation (SpO2) and arterial oxygen saturation (SaO2) was evaluated, Group l consisted of 102 samples of SpO2 using an Ohmeda pulse oximter in 45 of 72 patients. Group ll included 102 samples of SpO2 using a CSl pulse oximeter in 45 of 72 patients. Both Ohmeda and CSI pulse oximeters were applied to 32 patients. Group lll had 204 samples, thE Sum of Groups l and ll. The results were as follow ; 1) The correlation coefficients of SpO2 to SaO2 in Groups l, ll and lll were 0.97, 0.90 and 0.96 (p < 0.775). 2) Mean difference between SaO2 and SpO2 in Groups l, ll and lll were almost within the limit of 1%. 3) The correlation coefficient of SpO2 between Ohmeda andcsr pulse oximeter was 0.79, and there was no mean difference between them in the 32 patients who were tested with both the Ohmeda and the CSI pulse oximeters. In conclusion, a pulse oximter is an accurate noninvasive device which assesses arterial oxygenation and provides information continuously. Wider clinical indication will follow.

Inhalation induction of anesthesia is seldom used in a routine adult practice because of the long induction time and the prolonged excitement phase with the risk of laryngospasm and vomiting. So in modern practice, anesthesia is usually administered intravenously and produces unconsclousness pleasantly. However there are situaions where intravenous induction may not be ideal, and where rapid induction is still desired. The author wanted to evaluate the clinical application of inhalation induction of halothane using a vital capacity breath as a substitute for intravenous induction of anesthesia. The patients in this study had an ASA physical status of l or ll and presented no cardiopulmonary disease or abnormal laboratory data. The patients were divided into two group: a control group(n=30) and an experimental group(n=30). Control group: Intravenous induction with thiopental sodium. Experimental group: Inhalation induction with halothane using a vital capacity breath. The results are as follows: 1) The control group consisted of 14 males and 16 females. The mean age was 37.8+/-11.5years, and the ages ranged from 16 to 65 years. The mean body weight was 59.8+/-8.0kg, and body weights ranged from 44 to 75kg. in the experimental group, there were 17 males and 13 females. The mean age was 28.9+/-13.7 years, and the ages ranged from 18 to 65 years. The mean body weight was 57.4+/-8.1 kg, and body weight ranged from 43+/-75kg. 2) In the experimental group, the apnea time ranged from 20 to 105 sec, with a mean of 44.5+/-20.4 sec. The mean induction time was 76.7+/-32.1sec. and induction time ranged from 20 to 150 sec. There was no relationship between apnea time and induction time. 3) The hemodynamic changes were as follows: a. There were significantly greater changes in blood pressure and pulse rate during intubation and postintubation in the control group than in the experimental group(p<0.05). b. There were significant changes in blood pressure and pulse rate in the control group(p<0.05), but seemed not to be hazardous clinically. 4) Induction was impossible in two patients in the experimental group due to profuse secretion or excitement. 5) The side effects in the experimental group included coughs(5 cases), arrythmias(4), excitements(4) and secretion(1), respectively. 6) Postanesthetic comments in the experimental group:27 of the 28 patients remembered the anesthetic smells: 3 pleasantly, 20 moderately and 4 unpleasantly. In conclusion, inhalation induction of halothane using a vital capacity breath is a safe, acceptable and practical alternative to intravenous induction in cooperative adult patients.
