Background The use of isotonic electrolytic solutions for the intraoperative fluid management in children is largely recognized, but the exact composition still needs to be defined. Objectives The primary objective of this randomized controlled open trial was to compare the changes in chloride plasma concentration using two intraoperative isotonic fluid regimens (Sterofundin vs normal saline, both added with 1% of glucose) in children undergoing major surgery. Secondary objectives were to compare changes in other electrolytes, renal function, and the occurrence of hypoglycemia. Methods Children aged between 1 and 36 months, scheduled for major surgery, were randomized to receive Sterofundin or saline during the intraoperative time. Children with preoperative electrolyte abnormalities, hemodynamic instability, and severe renal or hepatic dysfunction were excluded. The primary outcome was the Δ of Cl− (Δ = change in plasma concentration between post- and pre-infusion), and secondary outcomes included Δ of other electrolytes and intraoperative hypoglycemia. Results A total of 240 patients were included in the two study sites and randomized to receive Sterofundin plus 1% glucose or normal saline plus 1% glucose, in a open fashion (229 were finally analyzed). Δ of Cl− and Mg++ was statistically less relevant in patients who received intraoperative Sterofundin, and Δ of the other electrolytes was comparable between the two study groups. Relative risk of hyperchloremia was significantly higher when large volumes were infused (over than 46.7 ml·kg−1), regardless of type of crystalloid infused. Hypoglycemia occurred in two of 229 patients. Conclusions Sterofundin is safer than normal saline in protecting young children undergoing major surgery against the risk of increasing plasma chlorides and the subsequent metabolic acidosis.

Objective: To present and compare with literature our experience with an electronic anesthesia-related incident reporting form as a quality control measure at Gaslini Children's Hospital over a 19-month period. Methods: All events that occurred between March 2009 and September 2010 were recorded. We adopted an electronic reporting form included in the online recording process of every anesthetic procedure. Events were divided into near misses and adverse events. Adverse events were further divided into incidents, minor events, and major events. Patients were divided into three age-groups: < 1, between 1 and 3, and >3 years. Results: A total of 12 850 anesthetics were performed. Eight (0.06%) near misses' and 108 (0.8%) adverse events were reported. Adverse events occurred more frequently in infants. Of 108 events, 35 (32.4%), 61 (56.5%), and 12 (11.1%) were classified as incidents, minor, and major events, respectively. Of all the adverse events, 66 (61%) were respiratory, 27 (25%) organizational, six (5%) drug-related, four (4%) cardiocirculatory, and five (5%) miscellaneous. Conclusions: Infants were at the highest risk to experience adverse events. Although experimental electronic incident reporting proved to be feasible, there is reason to suspect that there was underreporting of near misses. Overreporting of near miss events may be enhanced by easier and more straightforward reporting forms as well as by better education for anesthetic providers about the importance of recognizing and reporting near misses.

Clonidine has the potential to significantly prolong the duration of caudal epidural anesthesia. We investigated the effect of the addition of clonidine to the MLAC of levobupivacaine in a randomized controlled dose-response trial. A group of 120 children aged <6 years of age received caudal anesthesia with levobupivacaine and 1, 2, or 3 μg·kg of clonidine. The MLAC was determined according to a Dixon-Massey protocol. The primary outcome was effective surgical anesthesia. Secondary outcomes were the duration of postoperative analgesia, postoperative pain scores, clonidine side effects, and time to hospital discharge. The MLAC of caudal levobupivacaine was 0.106%, 0.077%, and 0.035% with 1, 2, and 3 μg·kg of clonidine, respectively. There were significant dose-dependent increases in median duration of analgesia. The incidence of delayed discharge, somnolence, and PONV was significantly increased in the 3 μg·kg of clonidine group. Clonidine produces a local anesthetic sparing effect with a dose-dependent decrease in levobupivacaine MLAC for caudal anesthesia. In addition, there is a dose-dependent prolongation of postoperative analgesia following lower abdominal surgery in children. A dose of 2 μg·kg of clonidine provides the optimum balance between improved analgesia and minimal side effects. [ABSTRACT FROM AUTHOR]
