Sixty children undergoing inguinal or urogenital surgery were allocated randomly to three groups to receive a caudal injection of either 0.125% bupivacaine 0.75 mL kg-1 with 0.5% midazolam 50 micrograms kg-1 (n = 20) or with 1% morphine chlorhydrate 0.05 mg kg-1 (n = 20), or bupivacaine alone (n = 20) after surgery under general anaesthesia. There were no significant changes in heart rate, blood pressure, respiratory rate or oxygen haemoglobin saturation values in all groups, and there were no significant differences in the incidence of vomiting and pruritus between the groups (P > 0.05). Sedation scores were higher in the bupivacaine-midazolam and the bupivacaine-morphine groups than in the bupivacaine group at 8-12 h post-operatively (P < 0.01). The durations of analgesia were 21.15 +/- 1.2 h in the bupivacaine-midazolam group, 14.50 +/- 1.6 h in the bupivacaine-morphine group and 8.15 +/- 1.3 h in the bupivacaine group. Differences between the bupivacaine-midazolam group and the bupivacaine group (P < 0.001), the bupivacaine-midazolam group and the bupivacaine-morphine group (P < 0.01), and the bupivacaine-morphine group and the bupivacaine group (P < 0.01) were significant. It is suggested that caudal administration of a bupivacaine-midazolam mixture produces a longer duration of post-operative analgesia than a bupivacaine-morphine mixture and bupivacaine alone with sedation for 8-12 h post-operatively.
In this study, soluble receptor of interleukin-2, interleukin-8, creatine kinase, and creatine kinase MB isoenzyme levels were determined serially before, during, and after cardiopulmonary bypass in blood samples of 24 patients. Interleukin-2 receptor levels were 683+/-80 U/ml in the preoperative period and 640+/-60 U/ml during hypothermia. Subsequently, these levels increased significantly at the end of the procedure (791+/-70 U/ml, P<0.01), remaining elevated 1 h after (882+/-92 U/ml, P<0.001) and reaching peak values 24 h postoperatively (1,752+/-200 U/ml, P<0.001). Preoperative plasma values of interleukin-8 were 230+/-43 pg/ml. Interleukin-8 concentrations were 185+/-25 pg/ml during hypothermia. The peak interleukin-8 levels were observed at the end of cardiopulmonary bypass (754+/-94 pg/ml, P<0.001) and tended to decrease 1 h after the procedure (643+/-76 pg/ml, P<0.001), declining to preoperative values, 24 h postoperatively (273+/-41 pg/ml). Interleukin-2 receptor levels correlated well with creatine kinase levels during the procedure. Furthermore, creatine kinase MB levels were correlated with interleukin-2 receptor values only at the end and 1 h after completion of cardiopulmonary bypass. We concluded that interleukin-8 and Interleukin-2 receptor levels are elevated after cardiopulmonary bypass and may contribute to myocardial injury as reflected by increased levels of creatine kinase and creatine kinase MB and correlations between interleukin-2 receptor and both creatine kinase and creatine kinase MB levels.
Amaç: Bu çalışmada, yoğun bakım ünitemizde (YBÜ) takip edilen intoksikasyon olgularında uygulanan plazmaferez tedavisinin etkinliğinin değerlendirilmesi amaçlanmıştır. Yöntem: Ocak 2014-Aralık 2015 tarihleri arasında YBÜ'de takip edilen ve plazmaferez uygulanan intoksikasyon olgularının demografik özellikleri, plazmaferez öncesi ve sonrası AST, ALT, LDH, CK ve total bilirubin değerleri kaydedildi. Yapılan plazmaferez tedavisi öncesi ve sonrasına ait bu değerler karşılaştırılarak işlemin etkinliği değerlendirildi. Bulgular: Çalışmaya 38 hasta dahil edilmiş olup, medyan 5,5 (1-106) günlük yatış süresinin sonunda 32 (%84,2) hasta taburcu edilmiş, 6 (%15,8) hasta ise kaybedilmiştir. Bu hastalara toplamda 61 (minimum 1, maksimum 4) kez plazmaferez uygulandı. Plazmaferez öncesi ve sonrası AST, ALT, LDH, CK ve total bilirubin değerleri karşılaştırıldığında plazmaferez sonrası bu değerlerde istatistiksel anlamlı düşme belirlendi (sırasıyla; p değeri <0001, <0.001, <0,001, =0,014, <0,001). Medyan 5,5 günlük yatış süresi sonunda eksitus olan hastalarda plazmaferez öncesi AST ve ALT değerleri istatistiksel anlamlı olarak daha yüksek bulundu (sırasıyla p değeri = 0.014, 0,046). Sonuç: Yoğun bakım ünitesinde çoğunlukla intoksikasyon nedeni ile uyguladığımız plazmaferez tedavisi laboratuvar değerlerinde hızlı iyileşme sağlayan güvenli bir yöntemdir. Ancak geliş AST ve ALT değerleri çok yüksek olan hastalarda mortalite üzerine olumlu etkisi gösterilememiştir.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
