Randomized Controlled Trial Comparative Study Clinical TrialComparison of diclofenac and tenoxicam for postoperative analgesia with and without fentanyl in children undergoing adenotonsillectomy or tonsillectomy.
127 children scheduled for elective tonsillectomy or adenotonsillectomy were studied. Anaesthesia was induced with propofol and maintained with a volatile agent. At induction the child received either rectal diclofenac 1 mg.kg-1 with or without fentanyl 0.75 microgram.kg-1 i.v., or intravenous tenoxicam 0.4 mg.kg-1 with or without fentanyl 0.75 microgram.kg-1 i.v. ⋯ Pain scores in the tenoxicam without fentanyl group were significantly higher in recovery (P < 0.05) than the diclofenac group without fentanyl and both fentanyl groups. This group required supplemental analgesia earlier although this was not significant. The pain scores in the diclofenac with fentanyl group were significantly lower at one h and four h than the group receiving diclofenac alone (P = 0.008 and 0.02 respectively).

Rett syndrome is a devastatingly disabling neurological disease that is only observed in girls. Scoliosis occurs in roughly half the girls and surgery may be required. ⋯ Sudden death may be a feature of the disease which occurred four weeks postoperatively in one case. Although a long QTc interval may be seen, it did not occur in any of our cases.

Randomized Controlled Trial Comparative Study Clinical TrialA comparison of 4.5% human albumin solution and Haemaccel in neonates undergoing major surgery.
In a randomized blinded study we compared two colloid solutions in 30 neonates undergoing major surgery. Fifteen neonates received 4.5% Human albumin solution (HAS) (mean volume 25.6 ml.kg-1, SD 9.5) and the others received Haemaccel (Hoechst) (24.9 ml.kg-1, SD 10). Pre and postoperative plasma albumin and haemoglobin concentrations and plasma colloid osmotic pressure (COP) were compared. ⋯ In the HAS group there was no significant change in either the plasma albumin concentration or COP. There was a small but significant decrease in the mean haemoglobin concentration from 15.92 to 14.35 g.dl-1 (mean difference 1.56, CI 0.57 to 2.55) after HAS. We conclude that HAS is the superior colloid for volume replacement in neonates undergoing surgery.

Case ReportsTotal spinal anaesthesia following caudal block with bupivacaine and buprenorphine.
This is a case report of an 18-month-old 10 kg child who presented for emergency repair of a recurrent diaphragmatic hernia with a history of craniofacial dystosis and was given a caudal block postoperatively with a combination of 4 ml of 0.5% bupivacaine and 2.5 micrograms.kg-1 buprenorphine made up to a total volume of 10 ml. An inadvertent dural puncture occurred resulting in total spinal block which was managed symptomatically. ⋯ The patient's exposure to a large intrathecal dose of buprenorphine did not lead to prolonged respiratory depression. The possibility of a midbrain insult due to a sudden rise in intracranial pressure is also discussed.

Case ReportsRespiratory depression following administration of low dose buprenorphine as postoperative analgesic after fentanyl balanced anaesthesia.
Opioids are among the most ancient and widely used drugs in anaesthesiology. The pharmacology of opioid analgesics and their receptors is a complex and not fully understood matter; even more complex are the interactions between different classes of opioids at both molecular and clinical levels. ⋯ This paper contains a clinical observation of respiratory depression following the administration of buprenorphine as postoperative analgesic after balanced anaesthesia with fentanyl. The observed case is interpreted in the light of the pharmacokinetics and pharmacodynamics of the different classes of opioid drugs (agonists, agonists-antagonists, antagonists) and of the interactions with their respective receptors.
