A review of nosocomial septicaemia in paediatric intensive care in a tertiary referral setting was undertaken for a 33-month period (1988-90). This involved six units: Cardiothoracic surgery; Neonatal surgery; general medical; Renal dialysis/transplant; Haematology/Oncology and Infectious disease/Immunology. The latter two units undertake bone marrow transplantation. ⋯ Coagulase-negative staphylococci were the most frequent isolates overall (43% of episodes in pure culture, and a further 6% in combination with other organisms). Staphylococcus aureus was associated with 10% of episodes, Enterobacteriaceae with 9% and Pseudomonas spp. 6% among which environmental pseudomonads predominated. Anaerobes and Haemophilus influenzae were each isolated in less than 1% of episodes.

Randomized Controlled Trial Multicenter Study Clinical TrialHypothermia in the sepsis syndrome and clinical outcome. The Methylprednisolone Severe Sepsis Study Group.
To evaluate the consequences of clinical hypothermia associated with sepsis syndrome and septic shock. ⋯ This prospective study confirms that hypothermia associated with sepsis syndrome has a significant relationship to outcome manifest by increased frequency of shock and death from shock. This finding is in sharp contrast to the protective effects of induced hypothermia in septic animals and perhaps man.

Gastric intramucosal pH: a noninvasive method for the indirect measurement of tissue oxygenation.
Monitoring the adequacy of tissue oxygenation is an important goal in the care of the critically ill patient. Global alterations in tissue oxygenation are inferred from changes in systemic oxygen transport (defined as the product of cardiac output and arterial oxygen content) and total oxygen consumption. These parameters, however, cannot measure the level of oxygenation of specific tissue beds, in particular those that are first affected by hypoxia, such as the gastrointestinal tract and the kidneys. ⋯ Gastrointestinal tonometry is a relatively noninvasive device that appears capable of measuring metabolic changes produced by hypoxia. Because of the sensitive nature of the gastrointestinal mucosa, these changes often occur well in advance of other, more common, indices of hypoxia. The use of the tonometer may become a routine procedure in the overall monitoring of critically ill patients.
