A case of severe visual loss following nitrous oxide anaesthesia in the presence of an intraocular perfluoropropane (C3F8) gas bubble is described. The diabetic patient had previously undergone vitreoretinal surgery at which time the gas had been inserted. The case highlights the use of long-acting intraocular gases in modern vitreoretinal surgery, and the measures that can be taken to prevent further such episodes.

Review Comparative Study
Applicability of risk scores for postoperative nausea and vomiting in adults to paediatric patients.
Scores to predict the occurrence of postoperative vomiting (PV) or nausea and vomiting (PONV) are well established in adult patients. The aim of this survey was to evaluate the applicability of risk scores developed and tested in adult patients in 983 paediatric patients (0-12 yr) undergoing various surgical procedures. ⋯ Specialized scores for children are required. These might use the history of PV, strabismus surgery, duration of anaesthesia > or =45 min, age > or =5 yr and administration of postoperative opioids as independent risk factors.

Randomized Controlled Trial Clinical Trial
Effect of pre-emptive ketamine on sensory changes and postoperative pain after thoracotomy: comparison of epidural and intramuscular routes.
In this study we have evaluated the efficacy of ketamine via i.m. and epidural routes for the control of post-thoracotomy pain. ⋯ The results of the present study demonstrate that pre-emptive epidural ketamine is effective in reducing intra- and postoperative analgesic requirements, hyperalgesia and touch allodynia.
