Abstract
The present study aimed at describing the profile of defining characteristics in patients with the nursing diagnosis "Fluid volume deficit" related to active loss of fluid secondary to burns. Data were collected by means of a tool, containing 29 possible defining characteristics of this diagnosis. Seven nurses, that worked at the Burnt Unit for at least five years ago, provided opinions about the degree to which each defining characteristic is indicative of this diagnosis. Nurses rated each defining characteristic of diagnosis being tested on a scale of zero to one. The results confirmed all, except one (increased body temperature) defining characteristics presented by NANDA for this diagnosis and indicated 10 new defining characteristics.

Abstract
Disturbances of the dopamine system are involved in the pathogenesis of idiopathic Parkinson's disease (PD). Although genetic factors may play a role in the etiology of PD, there is little direct evidence implicating a specific gene. We conducted a study to test the hypothesis that allelic variations of the dopamine receptors (D2, D3, D4) and the dopamine transporter (DAT) contribute to the susceptibility to PD. Association analyses of 70 Japanese PD patients and the same number of age-matched controls did not reveal any association between alleles of the D2, D3 or D4 receptor genes or the DAT gene and PD. Thus, our results suggest that factor(s) other than allelic variations of these key proteins in the dopamine system contribute to the susceptibility to PD.

Abstract
The risk of the future development of primary esophageal cancer after endoscopic esophageal mucosal resection of esophageal cancer is not known; hence, there are no established guidelines for follow-up surveillance programs. Simultaneous occurrence of multiple cancers associated with esophageal cancer is common among heavy drinkers who have the inactive form of aldehyde dehydrogenase-2 (ALDH2) as a risk factor. Thirty-four Japanese male alcoholics with intraepithelial or mucosal squamous cell carcinoma in the esophagus were treated by endoscopic esophageal mucosal resection, followed by endoscopy and esophageal iodine staining, to find the additional development of primary esophageal cancer. Primary esophageal squamous cell carcinoma was detected in nine patients (26.5%) at 3-21 months after the first cancer diagnosis. Cancer occurred more frequently in patients with inactive ALDH2 than it did in those with active ALDH2 [42.1% (8 of 19) versus 6.7% (1 of 15), P = 0.047], and it occurred more frequently in those with multiple esophageal cancers than it did in those without them [60.0% (6 of 10) versus 12.5% (3 of 24), P = 0.009]. Kaplan-Meier estimates of the proportions of patients with additional primary esophageal cancers showed that patients with inactive ALDH2 (P = 0.024) or multiple esophageal cancers (P = 0.007) had a significantly increased likelihood of the development of additional cancer. Close follow-up examinations using endoscopy and iodine staining are needed for such high-risk patients.

Abstract
The aggravation of bronchial asthma in today's urban child population was studied by an epidemiological study in order to elucidate the involvement of indoor air pollution in relation to housing style. The asthma group consisted of 210 children under 12 years old who had been recently diagnosed as having bronchial asthma and under the care of Osaka Prefectural Habikino Hospital. The non-asthma group consisted of 180 children under 12 years old who had been under care at Osaka Prefectural Hospital but had no present history of allergic symptom. The individual atmospheric environment and housing style were surveyed by questionnaire. Also, the amount of mite allergen (Dp: Dermatophagoides pteronyssinus, Df: Dermatophagoides farinae) in room and bedding dust and the concentration of cotinine in urine were examined as objective indicators for the load of environmental allergen and the indoor air pollution by tobacco smoke, respectively. In this study, bronchial asthma was classified into two types: atopic/non-atopic, according to whether Dp-specific immunoglobulin E (Dp-IgE) was present/absent (positive/negative). Thus, for the risk factors given above, their involvement in each type of asthma was examined by comparing the proportion of the exposed subjects between the three groups of atopic asthma, non-atopic asthma and non-asthma. As atopy is an important factor of child asthma, the relative risk (odds ratio) of Dp-IgE increase (atopy) was also determined for the same factors by logistic regression analysis in each of the asthma and non-asthma groups. The results are as follows: 1. Reinforced concrete housing material, which results in mal-ventilation, increased the load of indoor air pollutants such as tobacco smoke. 2. A higher amount of mite allergen in bedding dust increased Dp-IgE. 3. Heating with stove, which results in a higher room humidity as well as temperature, enhanced Dp proliferation and appeared to be involved in increasing the risk of atopic asthma. 4. Reinforced concrete housing material appeared to be involved in suppressing Dp-IgE and increasing the risk of non-atopic asthma. But some air pollutants such as tobacco smoke and mite allergen showed no relationship to these involvements.

Abstract
The aggravation of bronchial asthma in today's urban child population was studied by an epidemiological study in order to elucidate the involvement of food habits as well as individual factors such as age, sex, and history of atopic dermatitis, and the interaction with urban living environments. The asthma group consisted of 202 children under 12 years old who had been recently diagnosed as having bronchial asthma and under the care of Osaka Prefectural Habikino Hospital. The non-asthma group consisted of 81 children under 12 years old who had been under care at Osaka Prefectural Hospital but had no present history of allergic symptom. The individual factors and the urban living environments (atmospheric environment, housing style) were surveyed by questionnaire. Also, the mite (Dp: Dermatophagoides pteronyssinus, Df: Dermatophagoides farinae) specific immunoglobulin E (Dp-IgE, Df-IgE) and the composition of serum fatty acid were examined as objective indicators for atopy and dietary habits, respectively. In this study, bronchial asthma was classified into two types: atopic/non-atopic, according to whether Dp-IgE was present/absent (positive/negative). Thus, for the risk factors given above, their involvement in each type of asthma was examined. As atopy is an important factor of child asthma, the relative risk (odds ratio) of Dp-IgE increase (atopy) was also examined by logistic regression analysis in each of the asthma and non-asthma groups. The results are as follows: 1. As age increased, the risk of atopy increased but the risk of asthma decreased. 2. The risk of asthma increased as Dp-IgE rather than Df-IgE increased. 3. For the composition of serum fatty acid, the lower quartile ranking (LQR) group for a saturated fatty acid, stearic acid, and the upper quartile ranking (UQR) group for a mono-unsaturated fatty acid, oleic acid, had a higher risk of nonatopic asthma. 4. The LQR group for omega 6-poly-unsaturated fatty acid such as linoleic acid, had a lower risk of atopy. 5. The UQR group for a omega 3-poly-unsaturated fatty acid, eicosapentaenoic acid, had a higher risk of nonatopic asthma. The UQR of eicosapentaenoic acid and living environments within 25 m from a major road or housing of reinforced concrete structure showed involvement in synergistic increase in the risk of non-atopic asthma.

Abstract
We investigated the relationship between cardiac output and PETCO2 as well as blood PCO2 in 10 patients undergoing cardiac surgery of long duration under high-dose fentanyl anesthesia. After anesthetic induction, the minute ventilation was kept constant at 10 ml.kg-1 x 10 cycles.min-1 and a pulmonary artery catheter was inserted. PETCO2, PaCO2 and cardiac index (CI) were measured simultaneously. PaCO2 was corrected for body temperature, and alveolar dead space-to-tidal volume ratio was calculated as VD/VTalv = (PaCO2-PETCO2)/PaCO2. After body, temperature became stabilized, the measurements were started and repeated every 10 to 20 minutes during the prebypass period. One hundred and eight sets of data were taken from 10 patients. PETCO2 correlated positively with CI. Similarly, PaCO2 correlated positively with CI, but VD/VTalv, did not correlate with CI. PETCO2 correlated closely and positively with PaCO2, but it correlated negatively and only marginally with VD/VTalv. When examined in individual patients, PaCO2 correlated positively with PETCO2 in all patients, while VD/VTalv correlated negatively with PETCO2 only in 3 patients. By multiple regression analysis, VD/VTalv change accounted for only 22.3 +/- 15.0% of PETCO2 change, while PACO2 or PaCO2 change accounted for 77.6 +/- 15.0% of PETCO2 change. Decreased CI was associated with decreased CO2 delivery from the tissue to the lung (DCO2) and PaCO2 decreased with decreasing DCO2. Decreased CI was also associated with decreased oxygen uptake (VO2), and PaCO2 decreased with decreasing VO2. A decrease in CI resulted in an increase in VA/Q, and PaCO2 decreased when VA/Q increased. PETCO2 decreased when cardiac output decreased. A decrease in PACO2 explained the decrease in PETCO2 better than an increase in VD/VT did. Decreased cardiac output might cause hypocapnia through decreased CO2 delivery to the lung, decreased CO2 production and/or increased ventilation-to-perfusion ratio.

Abstract
Urinalysis was performed on nine body packers/smugglers who were referred to the emergency room of a hospital near the New Tokyo International Airport between September 1994 and February 1996. This analysis had rarely been used on suspected body packers in Japan. Only one of the nine body packers was a female. Foreign bodies were detected in the gastrointestinal tracts of the body packers by plain x-ray photography or computerized tomography, and the suspected drugs were cocaine (five cases), heroin (two cases), opiate (one case), and marijuana (one case). The results of urinalysis and confessions of the smugglers corresponded well for the latter three drugs (four cases). In two of the suspicious cocaine cases, opiates were detected along with cocaine by urinalysis, and the metabolites were confirmed by gas chromatography-mass spectrometry. The urinary screening tests of another two suspicious cocaine cases were negative. Opiates (morphine and codeine), but no cocaine metabolites, were detected in the urine of the subject who confessed to smuggling in cocaine only. It may be inferred from these results that urinalysis on body packers is beneficial to both the patient (body packer) and the physician in preventing the disastrous outcome of drug intoxication. It can also be concluded that there is a need for the prompt establishment of a protocol that includes urinalysis upon admission to the hospital for the management of body packers in Japan.

Abstract
To clarify the pathogenesis of the widely known but obscure syndrome of sudden death with hepatic fatty metamorphosis observed in alcohol abusers, we have scrutinized both the clinical and pathological data of 11 subjects who died under such circumstances between 1987 and 1993. Death followed several days of uninterrupted drinking often with little dietary intake. The notable clinical features on arrival at the emergency room were disturbance of consciousness (11/11), hypotension (4/6), hypothermia (3/5), hypoglycaemia (8/11), metabolic acidosis (6/6), renal dysfunction (11/11), and hyperammonaemia (5/5). The common hepatic pathology was the extensive appearance of numerous microvesicular fatty droplets in the hepatocytes together with varying degrees of macrovesicular fatty change; four subjects had an underlying cirrhosis. Death undoubtedly results from a variety of metabolic disturbances triggered by the combination of massive ethanol intake and starvation. The appearance of extensive microvesicular fatty change superimposed on macrovesicular fatty change was considered to be an associated phenomenon.

Abstract
We investigated the effects of cardiac output on PETCO2 in anesthetized patients. We studied 8 adult patients undergoing long-lasting lower abdominal surgery. Anesthesia was maintained with epidural combined with inhalational anesthesia. The minute ventilation volume was kept constant at 10 ml.kg-1 x 10 cycles.min-1. PETCO2, PaCO2, and cardiac index, (CI) by thermodilution method were measured simultaneously. PaCO2 was corrected for body temperature for comparison with PETCO2. Approximate value of alveolar dead space to tidal volume ratio was calculated as VD/ VTalv = (PaCO2-PETCO2)/PaCO2. The measurements were repeated every 10 to 20 minutes under the steady body temperature. One hundred and six sets of data were obtained from these patients. PETCO2 as well as PaCO2 correlated positively with CI, while VD/VTalv did not correlate with CI. PETCO2 correlated positively with PaCO2, while it did not correlate with VD/VTa1v. When examined in individual patients, PETCO2 correlated positively with CI in 7 patients. PaCO2 correlated positively with CI in 6 patients, while VD/VTa1v correlated negatively with CI only in 2 patients, in whom CI showed a large fluctuation. PaCO2 correlated positively with PETCO2 in 8 patient, while VD/VTa1v correlated negatively with PETCO2 only in 1 patient. By multiple regression analysis, VD/VTa1v change accounted for only 20.0 +/- 15.3% of PETCO2 change, while PACO2 or PaCO2 change accounted for 79.3 +/- 16.7%. Decreased CI was associated with a decrease in oxygen uptake (VO2), and PaCO2 correlated positively with VO2. Decreased CI was also associated with an increase in VA/Q, and PaCO2 correlated negatively with VA/Q. Thus, PETCO2 decreased with decreasing cardiac output. A decrease in PACO2 explained the decrease in PETCO2 better than an increase in VD/VT did. Decreased cardiac output caused hypocapnia through decreased CO2 production and/or increased ventilation to perfusion ratio i.e. relative hyperventilation.

Abstract
The goal of the present study was to compare the performance of two groups of nursing undergraduate students, submitted to two different teaching methods, in their ability to perform the intramuscular injection on clients needing the procedure. Both, control (CG) and experimental group (EG) (n = 35 each) were submitted to traditional method and instructional method respectively, according to the methodological procedure described by Nogueira (1995). The performance of the students was evaluated by a nurse who had no knowledge of the group each student belong. The nurse used the "check-list" in order to evaluate the performance of student. The results indicate that the time spent by the students of each group was approximately the same i.e. 9.4 min for CG and 9.3 for EG. The students of the control group showed ordinary performance (42.9%), good performance (48.9%) and very good performance (8.5%) whereas those of the EG showed ordinary performance (5.7%), good performance (60%) and very good performance (34.3%). The present results shows that the students are responsible by their own learning, motivating us to use new teaching methods on nursing undergraduate course.

Abstract
The results of toxicology screening of samples from 725 patients admitted to the Critical Care Medical Center (CCMC) of Nippon Medical School during a 10-month period from 1992-1993 (Group A) and a 4-month period from 1995-1996 (Group B) were discussed. We investigated the drug use of emergency patients using immunoassay. EMIT and Triage. The results were confirmed by Gas Chromatography/Mass Spectrometry (GC/MS). Blood samples were analyzed for ethanol (EtOH) by head space gas chromatography. Overall, 18% of the 725 cases tested positive for drugs, 13% for EtOH. Recently the positive rates of drugs and EtOH have been increasing. The positive rates for drugs in Group A and Group B were 15% and 23%, and EtOH were 11% and 17%, respectively. False positive cases caused by the cross-reactivity to analog were found in both EMIT and Triage. But the reliability of both methods was sufficient for clinical use. Rapid in easy toxicology screening can provide useful clinical information for patients admitted to a CCMC, especially for patients who have been injured, have sustained unknown-etiology consciousness disturbances, have CPAOA (Cardio Pulmonary Arrest on Arrival) or have committed drug abuse. We conclude that toxicology screening using immunoassay methods is suitable for use in an emergency center.

Abstract
We investigated the effects of low-dose prostaglandin E1 (PGE1) on serum and urinary concentrations of inorganic fluoride in 39 adult patients undergoing upper abdominal surgery. Anesthesia was maintained with a combination of N2O-O2-sevoflurane and thoracic epidural anesthesia. Twenty-two patients received infusion of PGE1 at a rate of 0.02 micrograms.kg-1.min-1 throughout surgery. Seventeen patients served as control by not receiving PGE1. Serum inorganic fluoride concentrations (FB) were determined before the induction of anesthesia and 0, 2 and 24 hours after the end of anesthesia. Urinary inorganic fluoride concentrations (FU) were determined before the induction of anesthesia, and 0, 24 and 48 hours after the end of anesthesia. These was no difference between PGE1 group and control group in anesthetic dose (MAC hours) of sevoflurane. In both groups, FB peaked at the end of anesthesia. In PGE1 group, UB peaked at the end of anesthesia, while in control group, it peaked 24 hours after anesthesia. There were differences between groups neither in FB nor in FU throughout the study period. The relationships between anesthetic dose and fluoride concentrations, however, differed significantly between the groups. In control group FB values of 0, 2 and 24 hours after anesthesia correlated positively with MAC hours, respectively, while in PGE1 group they did not. Similarly in control group, FU values of 24 and 48 hours after anesthesia correlated positively with MAC hours, respectively, while in PGE1 group, they did not. Thus in patients receiving high-dose sevoflurane, FB and FU tended to be lower in PGE1 group than in control group. In contrast, in PGE1 group, urinary excretion of fluoride during surgery correlated positively with MAC hours, while in control group, it did not. Urinary fluoride excretion during surgery was significantly greater in PGE1 group than in control group. These results suggested that PGE1 might prevent elevation of serum and urinary fluoride concentrations in patients receiving high-dose sevoflurane. This effect might result from enhanced urinary excretion of fluoride with PGE1.

Abstract
We investigated the effects of low-dose prostaglandin E1 (PGE1) on intra- and post-operative liver function in 109 adult patients undergoing upper abdominal surgery. Patients were divided into 2 groups; Control group (n = 42) and PGE1 group (n = 67). In PGE1 group, PGE1 was infused throughout surgery at a rate of 0.02 microgram kg-1 min-1. In both groups, anesthesia was maintained with a combination of inhalational and thoracic epidural anesthesia. Epidural anesthesia was maintained with 1.5% lidocaine infused epidurally at a constant rate (8 +/- 2 ml.hr-1). The continuous epidural infusion of lidocaine was initiated before surgery and discontinued at the end of surgery. Preoperative and postoperative liver function was evaluated with blood chemistry examination. Intraoperative liver function was evaluated in 84 patients (33 in control group and 51 in PGE1 group) by measuring plasma lidocaine concentration. Plasma lidocaine concentration was determined 1 and 3 hours after the initiation of lidocaine infusion and 0 and 2 hours after its termination. There were no differences between the groups in doses and infusion rates of lidocaine. In both groups, lidocaine concentration increased progressively as infusion was continued. Lidocaine concentration was significantly lower in PGE1 group than in control group at the end of the infusion. In 22 patients in control group and 35 in PGE1 group who received high-dose lidocaine (> 8 mg.kg-1), lidocaine concentration remained significantly lower in PGE1 group than in control group throughout the infusion period. The difference in lidocaine concentrations between the groups increased progressively as infusion was continued, though the doses and the infusion rates of lidocaine were not different between the groups. Postoperative liver function did not differ between the groups. Because removal of lidocaine from blood to liver parallels hepatic blood flow, the lower plasma lidocaine concentration in PGE1 group indicated that hepatic blood flow was higher and liver function was better-maintained with PGE1 during anesthesia and surgery. Low dose PGE1 thus improved intraoperative liver function during upper abdominal surgery.

Abstract
OBJECTIVE This study was designed to investigate in cognitively normal subjects the possible association between hypersensitive pupil dilation response to the cholinergic antagonist tropicamide and the presence of the apolipoprotein E epsilon 4 (APOE4) allele, a well-defined genetic risk factor for Alzheimer's disease. METHOD The authors measured tropicamide-induced changes in pupil area in 44 cognitively normal Japanese subjects with and without the APOE4 allele. RESULTS The subjects with the APOE4 allele had significantly greater increases in pupil area than the others. The significant correlation of changes in pupil area with age for the subjects with the APOE4 allele was lacking for those without this allele. CONCLUSIONS The results suggest that a hypersensitive pupil dilation response to tropicamide is already present in cognitively normal individuals with the APOE4 allele. This association also suggests the potential involvement of APOE4 in the mechanism of pupil dilation.

Abstract
We investigated the effects of low-dose prostaglandin E1 (PGE1) on intra- and post-operative renal function in 109 adult patients undergoing upper abdominal surgery. Anesthesia was maintained with a combination of thoracic epidural combined with inhalational anesthesia. Sixty-seven patients received PGE1 at a rate of 0.2 microgram.kg-1.min-1 throughout surgery. Forty-two patients, who did not receive PGE1, served as control. Pre- and post-operative renal function was evaluated with serum levels of BUN and creatinine (Cr), while intra-operative renal function was evaluated mainly with urine output and urine flow rate during anesthesia. Urinary Na excretion and creatinine clearance (Ccr) were determined during surgery in limited cases. Urine output and urine flow rate during anesthesia were greater in PGE1 group than in control group, whereas infusion volumes and infusion rates were not different between the groups. In PGE1 group, urine flow rate was greater during surgery than before surgery, while in control group, it was unchanged. Na excretion during anesthesia was also greater in PGE1 group than in control group. In control group, Na excretion and Ccr were smaller during surgery than before surgery, while in PGE1 group, they were unchanged. Postoperative serum BUN and creatinine levels were not different between the groups. Decreased Na excretion and decreased Ccr in control group indicated that renal function was depressed during surgery, whereas unchanged Ccr, unchanged Na excretion and increased urine flow rate in PGE1 group indicated that renal function was well-maintained during surgery with PGE1. Low-dose PGE1 thus prevented depression of renal function during surgical anesthesia.

Abstract
We investigated preoperative PaO2 and changes of PaO2/FIO2 (P/F) during the operation in 40 patients with gynecologic malignancies (ovarian cancer (O group) = 14 cases, endometrial cancer (E group) = 14 cases, cervical cancer (C group) = 12 cases). Preoperative chest X-ray and respiratory function test of our patients were within normal ranges (% VC > or = 80, % FEV 1.0 > or = 70). There were no differences among 3 groups in age, height, weight, % VC, or % FEV 1.0. Preoperative PaO2 values in the O group and E group were significantly lower than the normal value (100--age/4). Preoperative PaO2 and P/F values in the O group were significantly lower in comparison with those in the C group. We suggest, therefore, that it is necessary to measure preoperative PaO2 in patients with ovarian and endometrial cancer.

Abstract
We report five patients who developed intraoperative myocardial ischemia but were treated successfully with nicorandil. Case 1; An 84 year-old male underwent emergent laparotomy and ileolysis under inhalational plus thoracic epidural anesthesia. During his emergence from anesthesia, arterial pressure and heart rate increased abruptly due to excitement, leading to ST-T depression on V5 lead. Bradycardia and hypotension developed subsequently. Immediately after i.v. injections of nicorandil 4 mg and atropine 0.3 mg, ST-T change and hemodynamics improved dramatically. Case 2; A 67 year-old male underwent esophagectomy under inhalational plus thoracic epidural anesthesia. Following the completion of surgery, elevation of ST-T developed suddenly on lead II, though hemodynamics were not compromised. ST-T elevation disappeared immediately after nicorandil 6 mg and continuous infusion of nitroglycerin (TNG) was initiated. Case 3; A 71 year-old female underwent aortic valve replacement under high-dose fentanyl anesthesia. Shortly after starting cardiopulmonary bypass (CPB), ST-T segment on leads II and V5 was elevated suddenly. This was accompanied by severe pulmonary hypertension suggestive of severe left ventricular failure. Shortly after nicorandil 4 mg via a pulmonary artery (PA) catheter, ST-T segment returned to the baseline and pulmonary arterial pressure was normalized. Case 4; A 61 year-old male underwent coronary revascularization under high-dose fentanyl anesthesia. During weaning from CPB, elevation of ST-T segment occurred on leads II and V5. ST change improved, responding to nicorandil 6 mg en bolus via a PA catheter. Case 5; A 67 year-old male underwent coronary revascularization under high-dose fentanyl anesthesia. He was unable to be weaned from CPB for several hours because of frequent and repeated attacks of ventricular tachycardia and ventricular fibrillation. The arrhythmia did not respond to various kinds of treatments including intra-aortic balloon pumping and continuous infusions of inotropes, anti-arrhythmic drugs and anti-anginal drugs. In spite of repeated intracoronary injections of TNG, graft flow to the left anterior descending branch remained low at 40 ml.min-1. After an intracoronary injection of nicorandil 1 mg, however, blood flow increased to 100 ml.min-1, resulting in a marked reduction in frequency of ventricular arrhythmia. The patient came off bypass successfully. In each case, intraoperative myocardial ischemia was treated successfully with nicorandil. Neither hypotension nor arrhythmia resulted from its bolus injection. Nicorandil might be a useful therapeutic tool for myocardial ischemia during anesthesia.

Abstract
We describe a premature aging disorder in a 15-year-old girl with severe growth and developmental deficiency. Her clinical findings included osteosarcoma, nuclear and subcapsular cataracts, insulin-resistant diabetes mellitus, osteoporosis, epilepsy, foot ulcers, erythroid macrocytosis, and unusual facial appearance. Hyaluronic acid levels in serum and urine were normal. Cultured skin fibroblasts had a normal potential for in vitro growth. This finding represents a new and unique premature aging syndrome.

Abstract
We investigated the effects of low-dose prostaglandin E1 (PGE1) on circulation, respiration, and body temperature during surgical anesthesia. We studied 109 adult patients undergoing upper abdominal operations under thoracic epidural combined with inhalational anesthesia. Patients were divided into 2 groups; Control group (n = 42) and PGE1 group (n = 67). In PGE1 group, PGE1 infusion was started at the rate of 0.02 microgram.kg-1.min-1 before the induction of anesthesia and was terminated at the end of surgery. There were no differences between the groups in demographic, anesthetic and surgical characteristics. After treatment with PGE1, arterial pressure decreased slightly but significantly, resulting in lower arterial pressure in PGE1 group than in control group before the induction of anesthesia. After the induction of anesthesia, however, arterial pressure decreased significantly in both groups, and the differences in arterial pressure between the groups were not observed any more during surgery. Heart rate was not different between the groups throughout the study period. Intraoperative urine output was greater in PGE1 group than in control group. PaO2/FIO2 ratio was not different between the groups both before and during anesthesia. Rectal temperature remained slightly but significantly lower in PGE1 group throughout surgery. Rectal-to-palm temperature gradient tended to be smaller in PGE1 group 1 hour after the induction of anesthesia. Low-dose PGE1 reduced arterial pressure. However, the difference in arterial pressure between the groups was so small that the difference disappeared during surgery. Meanwhile, low-dose PGE1 increased urine output, suggesting that renal blood flow was better-maintained with PGE1. In spite of several investigations reporting an unfavorable effect of PGE1 on PaO2, low dose PGE1 did not affect PaO2 in this study. Finally low-dose PGE1 reduced core temperature, though slightly, probably through redistribution of the body heat.
