Arterial hypoxaemia is observed during operation and also in the recovery room. Hypoxaemia during operation may be due to altered pulmonary mechanical conditions, drug-induced physiological changes and technical errors. Early postoperative hypoxaemia is frequently observed after general anaesthesia and may, among other things, be due to diffusion hypoxaemia, hyperventilation-induced hypoventilation, residual curarization, hypoventilation induced by sedatives or analgesics and ventilation/perfusion alterations. The clinical significance of peroperative and early postoperative hypoxaemia is not yet elucidated and treatment consists primarily of increasing the oxygen concentration in the inspired air.

This article has discussed the phenomena of postoperative delirium in the PACU. Common causes have been reviewed and treatment strategies have been presented. Postoperative delirium is a challenging patient care problem that can jeopardize postoperative recovery. The critical care nurse who is astute to the possible causes of postoperative delirium and to treatments and interventions required will help to minimize the morbidity associated with postoperative delirium.

ReviewTotal hip arthroplasty. The role of antiinflammatory medications in the prevention of heterotopic ossification.
Postoperative prophylaxis with antiinflammatory medications, primarily indomethacin, is extremely effective in preventing the severest degrees of heterotopic ossification (HO) after a total hip arthroplasty (THA) and the recurrence of excised HO developed after a previous hip surgery. Prophylaxis with indomethacin should be given in 25-mg doses three times daily for at least three weeks, starting on the first postoperative morning. ⋯ However, although no major complications have been reported regarding the use of antiinflammatory medications in the prevention of HO after THA, orthopedic surgeons prescribing such treatment should be aware of their contraindications as well as early and late side effects. Since several antiinflammatory agents are reported to be effective in preventing HO, future reports dealing with HO after THA should always include information about the postoperative antiinflammatory treatment used.
