ReviewEffectiveness of dexmedetomidine use in general anesthesia to prevent postoperative shivering: a systematic review.
Postanesthetic shivering remains a significant source of distress following general anesthesia. Despite numerous studies investigating pharmacologic prophylaxis for postanesthetic shivering, no gold standard medication has been identified. Prophylactic dexmedetomidine administration has been examined as a possible preventative treatment modality for postanesthetic shivering; however its effectiveness has not been established. ⋯ The prophylactic administration of intravenous dexmedetomidine reduces the incidence of postanesthetic shivering in patients undergoing general anesthesia.

How to advance prediction of postoperative delirium? A secondary analysis comparing three methods for very early assessment of elderly patients after surgery and early prediction of delirium.
Postoperative impairment of the cerebral function can appear immediately after general anesthesia and may be predictive for a postoperative delirium. We compared three tools assessing patients on recovery room admission in order to detect early signs of postoperative brain dysfunction: the Postanesthetic Recovery Score (PARS), the Richmond Agitation-Sedation Scale (RASS) and the Nursing Delirium Screening Scale (Nu-DESC). ⋯ The RASS and Nu-DESC were independent predictors for a delirium within seven postoperative days. Very early assessment of the cerebral function may help to advance detection, prevention and treatment of postoperative delirium in elderly patients.

Background and Objective. Vitamin C has antioxidant, neuroprotective, and neuromodulating effects. Recently, it showed antinociceptive effect as a result of the antioxidant properties. ⋯ Conclusion. This study shows high dose vitamin C infusion decreased postoperative pain during the first 24 h and reduced morphine consumption in the early postoperative period. Additional research needed to examine whether higher doses of vitamin C and longer infusion times can amplify these effects.

Intravenous (IV) fluids are used ubiquitously when children undergo surgical procedures. Until recently, Holliday and Segar's guidelines for calculating maintenance fluids dictated fluid management strategies in postoperative pediatric patients. An increased recognition of hospital-acquired hyponatremia and its associated morbidity has led to a critical re-examination of IV fluid management in this population. ⋯ Recent studies have established that, as they are administered in current practice, hypotonic maintenance fluids are associated with increased rates of hyponatremia. The best available data demonstrate that administration of isotonic fluid reduces hyponatremic risk. In this review, we discuss the collective data available on the subject and offer guidelines for fluid management and therapeutic monitoring.
