In our continuing research into the determinants of laparoscopic working space, the influence of small body size was investigated. ⋯ Working space in growing individuals is very limited. Eighty percent of the working space created by an IAP of 15mm Hg was already achieved at 10mm Hg, while cardiorespiratory side effects at an IAP of 8-10mm Hg seem acceptable. Prestretching of the abdominal wall significantly increased working space, even more so than in 20-kg pigs. As in 20-kg pigs, NMB had no significant effect on laparoscopic working space. Prestretching of the abdominal wall is a promising cheap, safe and easy strategy to increase laparoscopic working space, lessening the need for prolonged high-pressure pneumoperitoneum.

Shock index (SI) (heart rate/systolic blood pressure)>0.9 predicts mortality in adult trauma patients. We hypothesized that age adjusted SI could more accurately predict outcomes in children. ⋯ A pediatric specific shock index (SIPA) more accurately identifies children who are most severely injured, have intraabdominal injury requiring transfusion, and are at highest risk of death when compared to shock index unadjusted for age.

Thoracoscopic operations in neonates, such as repair of oesophageal atresia and tracheooesophageal fistula or congenital diaphragmatic hernia, can be associated with intraoperative acidosis and hypercapnia in the absence of hypoxia. These derangements in intraoperative gas exchanges seem to be related to the insufflation and absorption of medical CO2. The effects on the developing brain are unknown, and further prospective investigations are needed to elucidate whether different strategies should be implemented to avoid these intraoperative problems.

The Hugh Greenwood Lecture acknowledges the extremely generous support from Mr Greenwood that has enabled the BAPS to establish funds to advance paediatric surgical training in developing countries. In this Inaugural Lecture, Dr. Sekabira, the first Hugh Greenwood Fellow, describes the influence that this has had on his career and reviews the state of paediatric surgery in Uganda.

Helicopter emergency medical services (HEMS) are a common mode of transportation for pediatric trauma patients. We hypothesized that HEMS improve outcomes for traumatically injured children compared to ground emergency medical services (GEMS). ⋯ HEMS do not independently improve outcomes for traumatically injured children, and 22.3% of children transported by HEMS are not significantly injured. These factors should be considered when requesting HEMS for transport of traumatically injured children.
