The specialty of anesthesiology has made extraordinary advances in anesthesia safety. Yet, anesthetic mortality and morbidity continue to be far from tolerable. Efforts to enhance safety in anesthesia must include adherence to explicit and implicit safety standards, must make use of equipment that offers modern safety features, must seek to detect and correct developing safety threats as early as possible and must have a structured system to analyze problems and to institute remedies to prevent their recurrence.

Correct indications are essential to perform surgical procedures. However, appropriate timing to achieve minimal rates of complications even in high-risk patients or major surgery is at the top of the priority list. Perioperative responsibility is divided between anaesthesiologists and surgeons. ⋯ Testing directed towards assessment of organ system functional reserve and identification of organs at risk rather than the diagnosis of a specific disease, is the primary goal of preoperative evaluation prior to surgery. These results are essential to prepare an effective anaesthetic plan. Along with increased patient comfort, the number of preoperative hospital days can be reduced by outpatient preoperative evaluation clinics.

The administration of paracetamol (in the US known as acetaminophen) to children and infants for postoperative pain after minor surgery is a well established and safe treatment option, if appropriately used. However, if paracetamol is dosed according to traditional recommendations (about 20 mg/kg body weight) frequently a sufficient analgetic effect cannot be achieved immediately after painful interventions. Recently, a higher initial dose (40 mg/kg body weight) was suggested for effective postoperative pain control, which seems especially important for children after ambulatory anesthesia, but may also be associated with certain risks to the patient. ⋯ In contrast, the risk for liver toxicity appears to be very low, if the daily paracetamol dose does not exceed 90 mg/kg body weight in otherwise healthy children, and if specific risk factors of the individual patient are always considered. This review discusses the recent publications on pharmacokinetics and -dynamics, the clinical use and dosing, as well as the risks and benefits of paracetamol for the treatment of postoperative pain in children and infants. Based on this information, specific dosing regimes for the postoperative period are suggested for neonates and infants, as well as for children in different age groups.
