Bispectral Index(BIS)およびTarget Controlled Infusion(TCI)を応用した新しい精密鎮静法を知的障害者歯科治療において試みた。ミダゾラムとプロポフォールの併用による静脈内鎮静法下での歯科治療を予定した3例を対象とした。処置内容等によりBIS値が変動したため、一定のBIS値を持続的に維持することは難しかったが、BIS値により浅鎮静および深鎮静を早期に予測することが可能であった。さらにTCIシステムを用いることにより、速やかに鎮静度を調節することができたため、至適鎮静度の維持は極めて容易であった。術中の合併症は、各症例で時折舌根沈下をみとめたがSpO2の低下は軽度で、下顎挙上にて対応可能であり、経鼻エアウェイ等が必要であった症例はなかった。また、術後合併症を認めたものはなく、全例が当日に帰宅可能であった。

自院における1999年4月から2004年3月までに行われた待機手術145例を対象に,手術室における同種輸血準備量,輸血実施状況,出血量およびcrossmatch-to-transfusion ratio(C/T比)を術式ごとに分類し,検討した.輸血実施率およびC/T比はType & Screen導入後は,導入前に比べて有意に少なく,いずれの時期でも出血量は術式に関係なく平均500ml以下であり,Type & Screenで問題なく対応できると思われた

In order to use transfusion blood effectively, maximum surgical blood order schedule (MSBOS) and Type and Screen (T & S) have been recommended. At Okayama University Dental Hospital, each responsible physician decided the blood preparation. A goal of this study was to analyze data related to transfusion during operation in Okayama University Dental Hospital, and compare it with the guidelines issued by the Ministry of Health, Labour and Welfare. Surgeries were divided into 6 categories: Tumorectomy, Tumorectomy and Neck dissection (ND), Radical and immediate reconstruction, Reconstruction, Benign tumorectomy, and Others. The cases were 145 cases operated from April 1, 1999 to March 31, 2004. Since Type and Screen (T & S) were introduced in the hospital in the middle of this period, the data were segregated by the introduction of the T & S. A transfusion ratio (percentage of transfusion per preparation) and ratio of cross-match to transfusion (C/T ratio) were calculated and compared with the guideline. Blood loss rate (> 600ml) was also figured out in each surgical category. Before the introduction of the T & S, in the "Radical and immediate reconstruction" category, transfusion ratio (percentage of transfusion per preparation) and ratio of cross-match and transfusion (C/T ratio) were 35.5% and 6.6, respectively. In the "Tumorectomy" category, the transfusion ratio and C/T ratio were 13.3% and 6.0, respectively. In the "Tumorectomy and ND" category the transfusion ratio and the C/T ratio were 7.9% and 24.9, respectively (Table 1, Fig. 2). In the "Radical and immediate reconstruction" category, much blood loss in occurred in 42% (Fig. 3) of the cases. Since the ideal value of the C/T ratio is 1.5 according to the guidelines, an amount of blood preparation before the introduction of the T & S was considered excessive in our facility (Fig. 1, 2). After the introduction of the T & S, all of the surgeries could be managed with the T & S (Table 2). However, in the "Radical and reconstruction" category, blood preparation should be considered for each case because of higher rate of large blood loss. Due to the introduction of the T & S, it became unnecessary to take the blood from the transfusion unit to an operation unit only for preparation. Thus, risks related to handling and transfer of blood can be reduced.

Analysis of autologous blood transfusion at the Okayama University Medical and Dental Hospital

Autologous transfusion is widely used in many surgical procedues because of its safety. It allows avoidance of infectious disease mediated by blood. At Okayama University Dental Hospital, cases of autologous transfusion has increased in the last several years. However, autologous transfsusion depends on the subjective judgement of the physician in charge of the patient. Therefore, we assessed the autologous transfusion in scheduled surgery performed in the last five years at our hospital. We investigated 198 cases. Most of the cases were repositioning of the mandible, the maxilla or both. The number of instances of each procedure were 93, 10 and 91, respectively. The mean values of blood loss were 169.9 ml, 232.5 ml and 330.2 ml, respectively (Fig. 1). The rates of cases in which blood loss was more than 600 ml were 4.3%, 0% and 11%, respectively (Fig. 2). The averages of amounts of autologous blood prepared were 409.6 ml, 382.2 ml and 448.3 ml, respectively (Fig. 3). For repositioning of both mandible and maxilla, a preserved autologous transfusion was prepared in 80.2% of the cases. For repositioning of the mandible, a dilutional autologous transfusion was prepared in 67.7% of the cases (Fig. 4). The preserved autologous transfusion was carried out in 9.5% of the cases involving repositioning of both mandible and maxilla, and in none of other repositioning surgeries (Fig. 5). Mean values of hemoglobin before surgeries in patients whose preserved autologous blood had been taken a couple of weeks prior to surgery were within normal range (Fig. 6). Since no homologous transfusion was necessary in any of the cases, we believe that one of the goals of autologous transfusion was achieved. However, preparing autologous transfusion may be done excessively for these procedures. Furthermore, since a small amount of dilutional autologous transfusion in our facility may not be effective, the preparation of autologous blood for the repositioning of the mandible should be re-assessed carefully.
