[Pediatric Pain Groups. Management related to pain in hospitalized children].
By means of multidisciplinary Pediatric Pain Groups in hospitals possibilities are created to implement recent knowledge about prevention of pain and relief of pain in children. The activities of these groups are amongst others: developing and testing pain protocols, applying systematic pain assessment and giving information about pediatric pain. These activities result in a reduction of pain in children and in prevention of needless suffering of pain in hospitalized children.

Postoperative analgesia and sedation following pediatric cardiac surgery using a constant infusion of ketamine.
Constant rate infusions of ketamine supplemented with intermittent doses of midazolam were given postoperatively to 10 children in order to provide analgesia and sedation during mechanical ventilation after cardiac surgery as well as during weaning from the ventilator and during spontaneous breathing. The aims of the study were to determine the pharmacokinetics of ketamine and evaluate the suitability of ketamine as an analgesic and sedative in postoperative pediatric cardiac patients. The children were between one week and 30 months old. ⋯ Norketamine did not reach a steady state, but at the end of the infusion, the mean plasma concentration was higher than that of ketamine. The elimination half-life of norketamine was estimated to be 6.0 +/- 1.8 hours. Both ketamine infusion regimens were supplemented with midazolam and provided similarly acceptable analgesia and sedation during mechanical ventilation and during and after weaning from the ventilator.(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Comparative Study Clinical Trial
Postoperative pulmonary complications. Epidural analgesia using bupivacaine and opioids versus parenteral opioids.
Different types of analgesia have been proposed for the prevention of postoperative respiratory complications. The aim of this prospective, double-blind randomized study was to compare the impact of epidural bupivacaine and opioids versus parenteral opioids on respiratory complications in patients who had undergone major abdominal surgery. ⋯ Epidural analgesia with a combination of local anesthetic and opioid improves patient comfort. However, this type of analgesia does not decrease the incidence of postoperative pulmonary complications, does not reduce the length of the hospital stay, and carries the risk of complications from episodic systemic hypotension.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of epidural tramadol and epidural morphine for postoperative analgesia.
The present study compared epidural tramadol with epidural morphine for postoperative analgesia in 20 patients undergoing major abdominal surgery. Intraoperatively, the patients were anaesthetized by a balanced technique of general anaesthesia combined with lumbar epidural lidocaine. In ten of the patients 100 mg tramadol diluted in 10 ml normal saline was also injected epidurally, while 4 mg epidural morphine was used in the other ten patients. ⋯ This was not associated with any increase in PaCO2 or a decrease of respiratory rate, suggesting that hypoxaemia rather than hypercarbia or decreased respiratory rate may be an earlier indicator of respiratory rate, suggesting that hypoxaemia rather than hypercarbia or decreased respiratory rate may be an earlier indicator of respiratory depression in patients breathing room air without oxygen supplementation. The absence of clinically relevant respiratory depression following epidural tramadol compared with epidural morphine may be attributed to the different mechanisms of their analgesic action. The results suggest that epidural tramadol can be used to provide prolonged postoperative analgesia without serious side effects.

Randomized Controlled Trial Clinical Trial
Epidural anaesthesia and analgesia do not affect energy expenditure after major abdominal surgery.
Our objective was to determine the effect of perioperative epidural anaesthesia and analgesia on the increase in energy expenditure which accompanies major elective abdominal surgery in a prospective, randomized study. Eight patients undergoing elective resections of the colon and/or rectum received general anaesthesia alone (nitrous oxide, oxygen, and isoflurane, supplemented with intravenous fentanyl to a maximum of 10 micrograms.kg-1), and 12 patients received perioperative epidural anaesthesia and analgesia using lidocaine (carbonated lidocaine 2% with epinephrine 1:200,000, 20 ml over 30 min) and morphine (preservative-free morphine 0.10 mg.kg-1 after catheter insertion and 0.05 to 0.10 mg.kg-1 every 12 hr as needed until the morning following surgery) via a lower lumbar catheter in addition to general anaesthesia. ⋯ Oxygen consumption, carbon dioxide production, and energy expenditure increased after surgery (all P < 0.001) but were very similar in the two groups (all P > or = 0.8) before and after surgery. Despite substantial effects on postoperative pain, we conclude that oxygen consumption and energy expenditure following major abdominal surgery are not diminished by perioperative epidural anaesthesia and analgesia.
