Comparative Study
Pulmonary function and inflammatory markers in patients undergoing coronary revascularisation with or without cardiopulmonary bypass.
Lung injury after cardiac surgery is believed to result from cardiopulmonary bypass and its pro-inflammatory effects. To test this hypothesis, we compared the oxygenation ratios, extravascular lung water indices and systemic and pulmonary tumour necrosis factor alpha (TNF-alpha) and interleukin (IL)-8 at predetermined intervals in coronary artery surgery patients with or without cardiopulmonary bypass. ⋯ Serum values of TNF-alpha and IL-8 increased in both groups but were higher in the cardiopulmonary bypass group (end of surgery: mean (SD) TNF-alpha 3.68 (2.5) vs 2.20 (1.2) pg.ml(-1) (p = 0.043 (CI 0.05-2.9)) and mean (SD) IL-8 19.45 (10.8) vs 6.31 (5.3) pg.ml(-1) (p = 0.001 (CI 6.9-19.3)). In broncho-alveolar lavage fluid, TNF-alpha and IL-8 increased in both groups with no differences between the groups.

Global Oximetry (GO) is an initiative launched recently in Uganda, India, the Philippines and Vietnam. The overall aims are to promote oximetry utilisation and reduce oximetry costs in lower income countries. Research objectives include studying the feasibility of cost reduction; overcoming non-cost barriers to global oximetry including issues of prioritization; education and guidelines; servicing and access to parts. Promotional objectives include creating new policy, influencing oximetry design, and setting new global standards for safer monitoring.

Randomized Controlled Trial
Comparison of the incidence and severity of cough induced by sufentanil and fentanyl: a prospective, randomised, double-blind study.
We compared the incidence and severity of cough following a bolus of sufentanil with that following fentanyl in 510 patients, randomly allocated to receive sufentanil 0.3 microg.kg(-1), fentanyl 3 microg.kg(-1) or 5 ml sterile water intravenously over 5 s. Coughing was graded depending on the number of coughs as mild (1-2), moderate (3-5) and severe (> 5). ⋯ Sufentanil was also associated with a lesser severity (p = 0.039) of coughing compared with fentanyl. We conclude that equipotent boluses of sufentanil and fentanyl increase the incidence of cough, although the incidence and severity of coughing with sufentanil are less than those with fentanyl.
